在(zai)饋(kui)(kui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系統4中(zhong)(zhong)(zhong)(zhong)(zhong)，基于(yu)從(cong)外(wai)部電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源9提供的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)，饋(kui)(kui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)置1中(zhong)(zhong)(zhong)(zhong)(zhong)的高(gao)頻(pin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)生成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路111將用于(yu)進行電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)輸送的預定高(gao)頻(pin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)(交流(liu)信號sac)提供至送電(dian)(dian)(dian)(dian)(dian)(dian)(dian)部110中(zhong)(zhong)(zhong)(zhong)(zhong)的送電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線圈(quan)l1以及電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容器c1p和(he)c1s(lc諧振電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路)。這(zhe)使得送電(dian)(dian)(dian)(dian)(dian)(dian)(dian)部110中(zhong)(zhong)(zhong)(zhong)(zhong)的送電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線圈(quan)l1中(zhong)(zhong)(zhong)(zhong)(zhong)產生磁(ci)場(磁(ci)通量)。此時，當作為饋(kui)(kui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)對象(xiang)設(she)備(bei)(充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)對象(xiang)設(she)備(bei))的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子設(she)備(bei)2a和(he)2b被放置于(yu)(或(huo)者被放置為接近(jin)于(yu))饋(kui)(kui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)置1的上(shang)(shang)表面(mian)(饋(kui)(kui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)表面(mian)s1)上(shang)(shang)時，在(zai)饋(kui)(kui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)表面(mian)s1的附近(jin)饋(kui)(kui)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)置1中(zhong)(zhong)(zhong)(zhong)(zhong)的送電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線圈(quan)l1與(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子設(she)備(bei)2a和(he)2b中(zhong)(zhong)(zhong)(zhong)(zhong)的受電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線圈(quan)l2相(xiang)互(hu)靠(kao)近(jin)。

以這(zhe)種(zhong)方(fang)式，當(dang)受(shou)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)圈(quan)l2被設(she)置成(cheng)(cheng)接(jie)近于(yu)生(sheng)成(cheng)(cheng)有磁(ci)場(磁(ci)通(tong)量(liang)(liang))的(de)(de)(de)送(song)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)圈(quan)l1時，通(tong)過(guo)受(shou)到由送(song)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)圈(quan)l1生(sheng)成(cheng)(cheng)的(de)(de)(de)磁(ci)通(tong)量(liang)(liang)的(de)(de)(de)感(gan)應而在受(shou)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)圈(quan)l2中(zhong)生(sheng)成(cheng)(cheng)了電(dian)(dian)(dian)(dian)動勢。換言之，由于(yu)電(dian)(dian)(dian)(dian)磁(ci)感(gan)應或(huo)磁(ci)共振，通(tong)過(guo)形成(cheng)(cheng)與送(song)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)圈(quan)l1和(he)受(shou)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)圈(quan)l2各者(zhe)的(de)(de)(de)交鏈而生(sheng)成(cheng)(cheng)了磁(ci)場。于(yu)是，進(jin)行了從送(song)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)圈(quan)l1側(ce)(ce)(ce)(初(chu)級(ji)(ji)側(ce)(ce)(ce)、饋(kui)電(dian)(dian)(dian)(dian)裝置1側(ce)(ce)(ce)或(huo)者(zhe)送(song)電(dian)(dian)(dian)(dian)部110側(ce)(ce)(ce))至(zhi)受(shou)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)圈(quan)l2側(ce)(ce)(ce)(次(ci)級(ji)(ji)側(ce)(ce)(ce)、電(dian)(dian)(dian)(dian)子設(she)備2a和(he)2b側(ce)(ce)(ce)或(huo)者(zhe)受(shou)電(dian)(dian)(dian)(dian)部210側(ce)(ce)(ce))的(de)(de)(de)電(dian)(dian)(dian)(dian)力輸送(song)(參(can)加(jia)圖2和(he)圖3中(zhong)的(de)(de)(de)箭(jian)頭p1)。此(ci)(ci)時，饋(kui)電(dian)(dian)(dian)(dian)裝置1側(ce)(ce)(ce)的(de)(de)(de)送(song)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)圈(quan)l1與電(dian)(dian)(dian)(dian)子設(she)備2a和(he)2b側(ce)(ce)(ce)的(de)(de)(de)受(shou)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)圈(quan)l2通(tong)過(guo)電(dian)(dian)(dian)(dian)磁(ci)感(gan)應等彼此(ci)(ci)磁(ci)耦合，以此(ci)(ci)使得在上述的(de)(de)(de)lc諧振電(dian)(dian)(dian)(dian)路中(zhong)進(jin)行lc諧振操作。

然(ran)后，在電(dian)(dian)(dian)(dian)(dian)子(zi)設備(bei)2a和2b的(de)各(ge)(ge)者(zhe)中(zhong)，通(tong)過(guo)受電(dian)(dian)(dian)(dian)(dian)線圈l2接受的(de)交流(liu)電(dian)(dian)(dian)(dian)(dian)被提供給整(zheng)流(liu)電(dian)(dian)(dian)(dian)(dian)路(lu)211、穩(wen)壓(ya)電(dian)(dian)(dian)(dian)(dian)路(lu)212和充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)路(lu)213，然(ran)后執行(xing)下面(mian)的(de)充電(dian)(dian)(dian)(dian)(dian)操作(zuo)。具體地，整(zheng)流(liu)電(dian)(dian)(dian)(dian)(dian)路(lu)211將上述交流(liu)電(dian)(dian)(dian)(dian)(dian)轉變成預定直流(liu)電(dian)(dian)(dian)(dian)(dian)，然(ran)后通(tong)過(guo)穩(wen)壓(ya)電(dian)(dian)(dian)(dian)(dian)路(lu)212進(jin)行(xing)穩(wen)壓(ya)操作(zuo)，然(ran)后充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)路(lu)213基于該直流(liu)電(dian)(dian)(dian)(dian)(dian)對電(dian)(dian)(dian)(dian)(dian)池214進(jin)行(xing)充電(dian)(dian)(dian)(dian)(dian)。以這種方(fang)式，在電(dian)(dian)(dian)(dian)(dian)子(zi)設備(bei)2a和2b的(de)各(ge)(ge)者(zhe)中(zhong)，基于通(tong)過(guo)受電(dian)(dian)(dian)(dian)(dian)部(bu)210接收的(de)電(dian)(dian)(dian)(dian)(dian)力而執行(xing)了充電(dian)(dian)(dian)(dian)(dian)操作(zuo)。

換(huan)言之，在(zai)本實施例中，在(zai)對(dui)電(dian)(dian)子設備(bei)2a和2b充電(dian)(dian)時，可以不需(xu)要例如與交流適配器等的(de)端子連接(jie)(jie)，并(bing)因(yin)此能夠通過僅將電(dian)(dian)子設備(bei)2a和2b放(fang)置于(或(huo)者(zhe)放(fang)置為接(jie)(jie)近于)饋(kui)電(dian)(dian)裝置1的(de)饋(kui)電(dian)(dian)表面s1上就輕(qing)易地(di)開(kai)始充電(dian)(dian)(進行非接(jie)(jie)觸式饋(kui)電(dian)(dian))。這減(jian)輕(qing)了(le)用戶的(de)負擔(dan)。

此外，例如，如圖(tu)5所示，在(zai)這(zhe)(zhe)樣的(de)(de)饋(kui)(kui)電(dian)(dian)(dian)操作時，饋(kui)(kui)電(dian)(dian)(dian)期(qi)(qi)(qi)(qi)間(jian)(jian)(jian)tp(電(dian)(dian)(dian)池214的(de)(de)充(chong)電(dian)(dian)(dian)期(qi)(qi)(qi)(qi)間(jian)(jian)(jian))和(he)(he)通信(xin)(xin)(xin)期(qi)(qi)(qi)(qi)間(jian)(jian)(jian)tc(非充(chong)電(dian)(dian)(dian)期(qi)(qi)(qi)(qi)間(jian)(jian)(jian))是(shi)以分時的(de)(de)方式周(zhou)(zhou)期(qi)(qi)(qi)(qi)性(xing)地(或者非周(zhou)(zhou)期(qi)(qi)(qi)(qi)性(xing)地)設定(ding)的(de)(de)。換句話說，控(kong)制(zhi)部112和(he)(he)控(kong)制(zhi)部216進行(xing)控(kong)制(zhi)以使得饋(kui)(kui)電(dian)(dian)(dian)期(qi)(qi)(qi)(qi)間(jian)(jian)(jian)tp和(he)(he)通信(xin)(xin)(xin)期(qi)(qi)(qi)(qi)間(jian)(jian)(jian)tc被設定(ding)為是(shi)分時周(zhou)(zhou)期(qi)(qi)(qi)(qi)性(xing)的(de)(de)(或分時非周(zhou)(zhou)期(qi)(qi)(qi)(qi)性(xing)的(de)(de))。通信(xin)(xin)(xin)期(qi)(qi)(qi)(qi)間(jian)(jian)(jian)tc是(shi)這(zhe)(zhe)樣的(de)(de)期(qi)(qi)(qi)(qi)間(jian)(jian)(jian)：在(zai)該期(qi)(qi)(qi)(qi)間(jian)(jian)(jian)內，在(zai)初級側(ce)設備(饋(kui)(kui)電(dian)(dian)(dian)裝(zhuang)置1)與次級側(ce)設備(電(dian)(dian)(dian)子設備2a或2b)之間(jian)(jian)(jian)進行(xing)使用送電(dian)(dian)(dian)線(xian)圈(quan)l1和(he)(he)受電(dian)(dian)(dian)線(xian)圈(quan)l2的(de)(de)預訂相互(hu)通信(xin)(xin)(xin)操作(用于設備間(jian)(jian)(jian)的(de)(de)認證、饋(kui)(kui)電(dian)(dian)(dian)效率控(kong)制(zhi)等的(de)(de)通信(xin)(xin)(xin)操作)(參見(jian)圖(tu)2和(he)(he)圖(tu)3中的(de)(de)箭頭c1)。應(ying)注意，在(zai)本例中饋(kui)(kui)電(dian)(dian)(dian)期(qi)(qi)(qi)(qi)間(jian)(jian)(jian)tp與通信(xin)(xin)(xin)期(qi)(qi)(qi)(qi)間(jian)(jian)(jian)tc的(de)(de)時間(jian)(jian)(jian)比可(ke)以是(shi)例如饋(kui)(kui)電(dian)(dian)(dian)期(qi)(qi)(qi)(qi)間(jian)(jian)(jian)tp：通信(xin)(xin)(xin)期(qi)(qi)(qi)(qi)間(jian)(jian)(jian)tc＝約(yue)9：1。

在通(tong)(tong)信期間(jian)tc內，例如可以進(jin)行(xing)(xing)交流信號(hao)生成電(dian)路111中使用(yong)脈寬(kuan)調制(zhi)的(de)(de)通(tong)(tong)信操(cao)作。具體地(di)，基于預定(ding)的(de)(de)調制(zhi)數據(ju)設定(ding)通(tong)(tong)信期間(jian)tc內的(de)(de)控制(zhi)信號(hao)ctl的(de)(de)占空比，以此進(jin)行(xing)(xing)基于脈沖(chong)寬(kuan)度調制(zhi)的(de)(de)通(tong)(tong)信。應注意，理(li)論上在送電(dian)部(bu)110和受電(dian)部(bu)210的(de)(de)上述諧振操(cao)作期間(jian)難以進(jin)行(xing)(xing)頻率調制(zhi)。因此，使用(yong)這樣的(de)(de)脈沖(chong)寬(kuan)度調制(zhi)來容易地(di)實現通(tong)(tong)信操(cao)作。

(2.關于充電期間(jian)內(nei)的送(song)電電力)

此外，在本實施例的(de)(de)饋電(dian)系(xi)統(tong)4中，在基于以(yi)上述方式利用磁場(chang)的(de)(de)送(song)電(dian)時(shi)的(de)(de)送(song)電(dian)電(dian)力(li)(li)(li)而(er)進行對(dui)電(dian)子設備2a和2b各者中的(de)(de)電(dian)池214的(de)(de)充(chong)電(dian)的(de)(de)期間內(nei)(nei)(在充(chong)電(dian)期間內(nei)(nei)或在充(chong)電(dian)完(wan)成之前)，送(song)電(dian)電(dian)力(li)(li)(li)被(bei)(bei)減(jian)小并(bing)被(bei)(bei)抑(yi)(yi)制為低電(dian)力(li)(li)(li)。換言之，在這樣(yang)的(de)(de)充(chong)電(dian)期間內(nei)(nei)，饋電(dian)裝(zhuang)置(zhi)1的(de)(de)控制部(bu)112控制送(song)電(dian)部(bu)110執行的(de)(de)送(song)電(dian)操作，以(yi)使得送(song)電(dian)電(dian)力(li)(li)(li)被(bei)(bei)減(jian)小并(bing)且(qie)被(bei)(bei)抑(yi)(yi)制為低電(dian)力(li)(li)(li)。這樣(yang)控制的(de)(de)一個原(yuan)因如下。

具體地，首先，例(li)如(ru)(ru)(ru)，如(ru)(ru)(ru)圖(tu)(tu)6和(he)(he)圖(tu)(tu)7所(suo)示(shi)，當(dang)電(dian)(dian)(dian)(dian)池214由諸如(ru)(ru)(ru)鋰離(li)子電(dian)(dian)(dian)(dian)池等二(er)次(ci)電(dian)(dian)(dian)(dian)池構成(cheng)時(shi)，通常可(ke)(ke)以(yi)(yi)(yi)基(ji)于所(suo)謂的(de)(de)“cc-cv充(chong)電(dian)(dian)(dian)(dian)”進行對二(er)次(ci)電(dian)(dian)(dian)(dian)池的(de)(de)充(chong)電(dian)(dian)(dian)(dian)。換言之，進行充(chong)電(dian)(dian)(dian)(dian)控制(zhi)以(yi)(yi)(yi)使得恒(heng)壓充(chong)電(dian)(dian)(dian)(dian)(cv充(chong)電(dian)(dian)(dian)(dian))期間(jian)tcv被設(she)定為跟隨(sui)著恒(heng)流充(chong)電(dian)(dian)(dian)(dian)(cc充(chong)電(dian)(dian)(dian)(dian))期間(jian)tcc。在這(zhe)樣的(de)(de)cc-cv充(chong)電(dian)(dian)(dian)(dian)時(shi)，電(dian)(dian)(dian)(dian)池214的(de)(de)負(fu)載(zai)特性(充(chong)電(dian)(dian)(dian)(dian)時(shi)間(jian)與負(fu)載(zai)的(de)(de)大小之間(jian)的(de)(de)關系)可(ke)(ke)以(yi)(yi)(yi)例(li)如(ru)(ru)(ru)如(ru)(ru)(ru)圖(tu)(tu)6所(suo)示(shi)，充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)路213的(de)(de)負(fu)載(zai)特性可(ke)(ke)以(yi)(yi)(yi)例(li)如(ru)(ru)(ru)如(ru)(ru)(ru)圖(tu)(tu)7所(suo)示(shi)。換言之，如(ru)(ru)(ru)圖(tu)(tu)6和(he)(he)圖(tu)(tu)7中各(ge)者的(de)(de)虛線(xian)箭頭所(suo)示(shi)，隨(sui)著對電(dian)(dian)(dian)(dian)池214的(de)(de)充(chong)電(dian)(dian)(dian)(dian)的(de)(de)進行，送電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)力(li)(li)與充(chong)電(dian)(dian)(dian)(dian)時(shi)必要(yao)的(de)(de)電(dian)(dian)(dian)(dian)力(li)(li)之間(jian)出現(xian)差(cha)距(ju)(ju)，且如(ru)(ru)(ru)果差(cha)距(ju)(ju)保持不(bu)變，那么與該差(cha)距(ju)(ju)相對應的(de)(de)量就變成(cheng)“剩余電(dian)(dian)(dian)(dian)力(li)(li)((過剩的(de)(de)(不(bu)必要(yao)的(de)(de))送電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)力(li)(li))”。這(zhe)樣的(de)(de)剩余電(dian)(dian)(dian)(dian)力(li)(li)最終變成(cheng)使饋電(dian)(dian)(dian)(dian)裝置1以(yi)(yi)(yi)及電(dian)(dian)(dian)(dian)子設(she)備2a和(he)(he)2b發熱(re)的(de)(de)“熱(re)”，因此是一個問(wen)題。

為此(ci)，在本(ben)實施例(li)中(zhong)，在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池214的(de)(de)(de)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)期間內(nei)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子設備(bei)2a和2b均未被啟動的(de)(de)(de)期間內(nei)，控制部(bu)112進行用于使送電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力階(jie)梯式地(di)減小(xiao)(xiao)至(zhi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)必(bi)需(xu)的(de)(de)(de)最小(xiao)(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力值的(de)(de)(de)控制。此(ci)外，在充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)期間內(nei)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子設備(bei)自(zi)身未被啟動的(de)(de)(de)期間內(nei)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子設備(bei)2a和2b中(zhong)的(de)(de)(de)控制部(bu)216將(jiang)用于使送電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力階(jie)梯式地(di)減小(xiao)(xiao)至(zhi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)必(bi)需(xu)的(de)(de)(de)最小(xiao)(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力值的(de)(de)(de)請求通知給饋電(dian)(dian)(dian)(dian)(dian)(dian)(dian)裝(zhuang)置1(控制部(bu)112)側。

在(zai)該(gai)操作示例中(zhong)(zhong)，如(ru)圖(tu)中(zhong)(zhong)箭頭(tou)p21所示，響應于來(lai)自(zi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)設(she)備2a和2b中(zhong)(zhong)各者(控(kong)制(zhi)部216)的(de)(de)(de)請(qing)求，控(kong)制(zhi)部112通過一(yi)次一(yi)個等(deng)級地(di)減(jian)小(xiao)(或增大)送(song)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力來(lai)階梯式(shi)地(di)降低所述送(song)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力。這樣控(kong)制(zhi)的(de)(de)(de)一(yi)個原因(yin)如(ru)下。具(ju)體地(di)，首先，例如(ru)，當如(ru)該(gai)圖(tu)中(zhong)(zhong)的(de)(de)(de)箭頭(tou)p22所示地(di)減(jian)輕負載22時，諸(zhu)如(ru)上述的(de)(de)(de)輸(shu)入至(zhi)(zhi)穩(wen)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)212的(de)(de)(de)輸(shu)入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)v1等(deng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)可能(neng)上升。因(yin)此，限(xian)定(ding)該(gai)輸(shu)入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)v1的(de)(de)(de)最小(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)值(zhi)(稍后說明(ming)的(de)(de)(de)閾值(zhi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)vth1；確保(bao)穩(wen)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)212(例如(ru)，開關調節器)的(de)(de)(de)操作的(de)(de)(de)輸(shu)入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)v1的(de)(de)(de)大小(xiao))，并且將(jiang)送(song)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力逐漸(一(yi)次一(yi)個等(deng)級地(di))減(jian)小(xiao)至(zhi)(zhi)不低于該(gai)最小(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)值(zhi)的(de)(de)(de)程度。

(2-1.比較例)

然(ran)而，在當負載22的(de)(de)(de)輕載狀態(tai)繼續(xu)時(shi)這樣減小送(song)電電力的(de)(de)(de)情(qing)況下，當如圖(tu)中(zhong)的(de)(de)(de)箭頭p31所示地啟動(dong)(諸如通(tong)過定時(shi)器等的(de)(de)(de)自動(dong)啟動(dong)和(he)用戶的(de)(de)(de)手(shou)動(dong)啟動(dong)等等)電子設備2a和(he)2b中(zhong)的(de)(de)(de)各(ge)者(負載22)時(shi)，在比較例中(zhong)會出現下面的(de)(de)(de)問題。

具體地(di)，首先，此時(shi)的(de)送電電力(li)(li)(li)可能明顯(xian)低(di)于(yu)負(fu)(fu)載22所(suo)需(xu)的(de)最(zui)大電力(li)(li)(li)。在(zai)這樣(yang)的(de)過載的(de)情況下(xia)，盡管(guan)電力(li)(li)(li)對于(yu)充電電路(lu)213而言是必(bi)要的(de)，但是具有減小了的(de)送電電力(li)(li)(li)的(de)穩(wen)(wen)壓(ya)(ya)電路(lu)212(例(li)如，開關(guan)調(diao)節(jie)器(qi))無法將電力(li)(li)(li)提供(gong)給(gei)充電電路(lu)213。因此，通過利用累積在(zai)電池(chi)214中(zhong)的(de)一(yi)部分充電電力(li)(li)(li)，充電電路(lu)213將電力(li)(li)(li)提供(gong)給(gei)負(fu)(fu)載22。在(zai)這樣(yang)的(de)狀(zhuang)態下(xia)，輸(shu)入至(zhi)穩(wen)(wen)壓(ya)(ya)電路(lu)212的(de)輸(shu)入電壓(ya)(ya)v1突然下(xia)降(jiang)，并(bing)且(qie)穩(wen)(wen)壓(ya)(ya)電路(lu)212進入所(suo)謂的(de)uvlo(undervoltagelockout：欠壓(ya)(ya)鎖定)模式。換句話說，由開關(guan)調(diao)節(jie)器(qi)等構(gou)成(cheng)的(de)穩(wen)(wen)壓(ya)(ya)電路(lu)212停止其功(gong)能，并(bing)且(qie)不將電力(li)(li)(li)供(gong)給(gei)至(zhi)充電電路(lu)213。

在(zai)這(zhe)樣的(de)(de)uvlo模(mo)(mo)式下(xia)(xia)，處(chu)于(yu)啟(qi)(qi)動狀(zhuang)態中的(de)(de)負載(zai)(zai)22如上所(suo)述地(di)(di)被供給有來自充電(dian)(dian)電(dian)(dian)路213的(de)(de)一部分充電(dian)(dian)電(dian)(dian)力，且因此運行平穩。另一方面，uvlo模(mo)(mo)式下(xia)(xia)的(de)(de)穩壓電(dian)(dian)路212是非常輕的(de)(de)電(dian)(dian)負載(zai)(zai)。因此，在(zai)負載(zai)(zai)22的(de)(de)啟(qi)(qi)動期間(啟(qi)(qi)動狀(zhuang)態期間ton)內，如圖中的(de)(de)箭頭p103所(suo)示(shi)，因為即使負載(zai)(zai)22處(chu)于(yu)重載(zai)(zai)狀(zhuang)態穩壓電(dian)(dian)路212也(ye)是非常輕的(de)(de)負載(zai)(zai)，所(suo)以送電(dian)(dian)電(dian)(dian)力穩定地(di)(di)減小。

以(yi)這樣的(de)方式，在圖8的(de)(b)部分(fen)所(suo)示(shi)的(de)比(bi)較例(li)中，盡管有(you)必要增大(da)送電電力并且(qie)具(ju)有(you)足夠的(de)輸送能力，但(dan)是送電電力穩(wen)定地減小，且(qie)因此，電池(chi)214的(de)剩(sheng)余電量持續減小，這損害(hai)了(le)用戶的(de)便利性(xing)。

(2-2.本實(shi)施例)

因此(ci)，在(zai)(zai)本(ben)實施(shi)例的饋(kui)(kui)電(dian)(dian)(dian)(dian)系統4中(zhong)，當在(zai)(zai)電(dian)(dian)(dian)(dian)池214的充電(dian)(dian)(dian)(dian)期間(jian)內電(dian)(dian)(dian)(dian)子設(she)備2a和(he)2b中(zhong)的各者被啟動(dong)時，饋(kui)(kui)電(dian)(dian)(dian)(dian)裝置(zhi)1的控制(zhi)部(bu)112控制(zhi)送電(dian)(dian)(dian)(dian)部(bu)110的送電(dian)(dian)(dian)(dian)操作以增大送電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)力(見圖8的(c)部(bu)分中(zhong)的箭頭p32)。此(ci)外，一旦判定在(zai)(zai)這(zhe)樣的充電(dian)(dian)(dian)(dian)期間(jian)內電(dian)(dian)(dian)(dian)子設(she)備自身(shen)(負載(zai)22)被啟動(dong)，電(dian)(dian)(dian)(dian)子設(she)備2a和(he)2b中(zhong)的各者的控制(zhi)部(bu)216側(ce)就(jiu)將(jiang)用(yong)于增大送電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)力的請求通知給饋(kui)(kui)電(dian)(dian)(dian)(dian)裝置(zhi)1側(ce)(控制(zhi)部(bu)112)。

此(ci)時，通(tong)(tong)過利(li)用與(yu)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)設備2a和2b的(de)(de)通(tong)(tong)信，控制部112檢(jian)測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)設備2a和2b中(zhong)的(de)(de)各者是(shi)否處于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)池214的(de)(de)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)期(qi)間內，并且檢(jian)測(ce)電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)設備2a和2b中(zhong)的(de)(de)各者(負(fu)載22)是(shi)否處于(yu)啟動(dong)狀(zhuang)態。此(ci)外，通(tong)(tong)過利(li)用與(yu)饋電(dian)(dian)(dian)(dian)(dian)(dian)裝(zhuang)置1的(de)(de)通(tong)(tong)信，控制部216通(tong)(tong)知饋電(dian)(dian)(dian)(dian)(dian)(dian)裝(zhuang)置1(控制部112)側(ce)。在本實施例中(zhong)，對(dui)送(song)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)這(zhe)樣的(de)(de)控制造成(cheng)了(le)與(yu)比(bi)較例不同(tong)的(de)(de)如下(xia)結果。具體地(di)，如上所述，即使在充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)期(qi)間內送(song)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)被減小和抑制為(wei)低的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)，電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)設備2a和2b中(zhong)的(de)(de)各者也能(neng)夠容(rong)易地(di)借助于(yu)送(song)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)確保其設備自身啟動(dong)所必需的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)。

應(ying)注意，在這(zhe)個(ge)過(guo)程中，如(ru)圖8的(de)(c)部分中的(de)箭頭(tou)p33和(he)(he)對(dui)角陰影部分所(suo)示，在送電(dian)(dian)電(dian)(dian)力響應(ying)于(yu)增大(da)(da)送電(dian)(dian)電(dian)(dian)力的(de)請求而實(shi)際增大(da)(da)之前的(de)期(qi)間(jian)(jian)內(nei)，控制部216進行控制以使得(de)使用累積(ji)在電(dian)(dian)池(chi)214中的(de)一部分充電(dian)(dian)電(dian)(dian)力來進行負載(zai)22的(de)啟動操(cao)作(zuo)。這(zhe)是因為這(zhe)個(ge)期(qi)間(jian)(jian)對(dui)應(ying)于(yu)從(cong)電(dian)(dian)子設(she)備2a和(he)(he)2b側到(dao)饋電(dian)(dian)裝置1側的(de)通(tong)信的(de)時(shi)滯，且在這(zhe)個(ge)期(qi)間(jian)(jian)內(nei)，有必要通(tong)過(guo)從(cong)充電(dian)(dian)電(dian)(dian)力接收支持來進行啟動操(cao)作(zuo)。

(電子(zi)設備2a和2b中的示(shi)例性控制)

在這里(li)，圖9在流程(cheng)圖中(zhong)(zhong)圖示(shi)了電(dian)子設(she)備2a和2b的(de)(de)各者中(zhong)(zhong)的(de)(de)控(kong)制(zhi)部216的(de)(de)具體控(kong)制(zhi)示(shi)例(充電(dian)期(qi)間內的(de)(de)控(kong)制(zhi)示(shi)例)。在控(kong)制(zhi)示(shi)例中(zhong)(zhong)，首先，在受電(dian)部210中(zhong)(zhong)進行(xing)正常的(de)(de)受電(dian)操作(接收100％的(de)(de)送電(dian)電(dian)力的(de)(de)操作)(步(bu)驟(zou)s101)。

接著，控制(zhi)部216重置(初始化)預定的(de)受電(dian)(dian)計數器(count＝0：步驟s102)。其(qi)后(hou)，通過使用作為上述設備信(xin)息(xi)的(de)剩(sheng)余(yu)電(dian)(dian)量(liang)信(xin)息(xi)，控制(zhi)部216判(pan)(pan)斷電(dian)(dian)池(chi)214中(zhong)的(de)剩(sheng)余(yu)電(dian)(dian)量(liang)是(shi)否(fou)等于或大于預定閾值(zhi)，即，對電(dian)(dian)池(chi)214的(de)充電(dian)(dian)是(shi)否(fou)完成(步驟s103)。具(ju)體地，在這(zhe)里(li)，判(pan)(pan)斷電(dian)(dian)池(chi)電(dian)(dian)壓vb是(shi)否(fou)等于或大于預定閾值(zhi)電(dian)(dian)壓vth。

這(zhe)里，一(yi)旦判定電池(chi)電壓vb等于或大(da)于閾值電壓vth(步(bu)驟s103：是)，控制(zhi)部(bu)216就確(que)定完成了對電池(chi)214的(de)充(chong)電，并且將這(zhe)一(yi)結果通(tong)知給(將充(chong)電完成指(zhi)(zhi)令傳輸至)饋電裝置(zhi)1(控制(zhi)部(bu)112)側(ce)(步(bu)驟s104)。這(zhe)使圖(tu)9所示的(de)充(chong)電期間內的(de)由控制(zhi)部(bu)216進(jin)行的(de)控制(zhi)結束。應注(zhu)意，利用與饋電裝置(zhi)1的(de)通(tong)信(xin)進(jin)行這(zhe)個(ge)通(tong)知(充(chong)電完成指(zhi)(zhi)令)。

另(ling)一方面，一旦判定電(dian)(dian)(dian)池電(dian)(dian)(dian)壓vb小于(yu)閾(yu)(yu)值(zhi)電(dian)(dian)(dian)壓vth(步(bu)驟s103：否)，控制部216就確(que)定還沒(mei)有完成對電(dian)(dian)(dian)池214的(de)充電(dian)(dian)(dian)，并且(qie)使受電(dian)(dian)(dian)計(ji)(ji)數器(qi)的(de)值(zhi)增加1(count＝count+1：步(bu)驟s105)。控制部216然后判斷受電(dian)(dian)(dian)計(ji)(ji)數器(qi)的(de)值(zhi)是(shi)否等于(yu)或大于(yu)預定閾(yu)(yu)值(zhi)th(是(shi)否滿(man)足count≥th)(步(bu)驟s106)。

在這里，當判(pan)定受電(dian)計(ji)(ji)數器(qi)的(de)值(zhi)小于閾(yu)值(zhi)th(count<th)(步(bu)驟s106：否)時，流(liu)程(cheng)返回到上述的(de)步(bu)驟s103。另(ling)一方面，一旦判(pan)定受電(dian)計(ji)(ji)數器(qi)的(de)值(zhi)等于或大于閾(yu)值(zhi)th(count≥th)(步(bu)驟s106：是)，控制部216隨后就通(tong)過使用作為設備信息的(de)上述啟動(dong)狀態(tai)信息來判(pan)斷設備自身(負載22)是否被啟動(dong)(步(bu)驟s107)。

在這里(li)，一旦判定負載(zai)22被啟動(dong)(dong)(步驟s107：是)，控(kong)(kong)制部216就如(ru)上所述(shu)地(di)將用(yong)于增大供電電力(li)(li)的(de)請求(qiu)通(tong)知給(將必需送電電力(li)(li)請求(qiu)指令發送至)饋(kui)電裝(zhuang)置(zhi)1側(控(kong)(kong)制部112)(步驟s108)。換句話(hua)說，控(kong)(kong)制部216將請求(qiu)通(tong)知給饋(kui)電裝(zhuang)置(zhi)1側，以使供電電力(li)(li)達到啟動(dong)(dong)時所必需的(de)電力(li)(li)值。這個通(tong)知(必需送電電力(li)(li)請求(qiu)指令)也是利用(yong)與饋(kui)電裝(zhuang)置(zhi)1的(de)通(tong)信(xin)而進行的(de)。應注(zhu)意，流程此(ci)后返回(hui)至上述(shu)的(de)步驟s102。

另一方面，一旦判定負載22沒有(you)被(bei)啟動(步(bu)驟(zou)s107：否)，控制部216隨后就判斷輸(shu)入(ru)至(zhi)穩壓(ya)(ya)電(dian)(dian)(dian)路(lu)212的輸(shu)入(ru)電(dian)(dian)(dian)壓(ya)(ya)v1是大(da)于還是小(xiao)于與充電(dian)(dian)(dian)必需的最小(xiao)電(dian)(dian)(dian)力(li)值(zhi)相(xiang)對應(ying)(ying)(ying)的閾(yu)值(zhi)電(dian)(dian)(dian)壓(ya)(ya)vth1(步(bu)驟(zou)s109)。應(ying)(ying)(ying)注(zhu)意，如上所述(shu)，閾(yu)值(zhi)電(dian)(dian)(dian)壓(ya)(ya)vth1對應(ying)(ying)(ying)于輸(shu)入(ru)電(dian)(dian)(dian)壓(ya)(ya)v1的這樣的大(da)小(xiao)：該輸(shu)入(ru)電(dian)(dian)(dian)壓(ya)(ya)v1的大(da)小(xiao)確保穩壓(ya)(ya)電(dian)(dian)(dian)路(lu)212(例如，開(kai)關調(diao)節器(qi))的操(cao)作。

在(zai)這(zhe)里，當輸入電(dian)(dian)壓v1大于(yu)(yu)閾值電(dian)(dian)壓vth1(v1>vth1，步(bu)驟s109：是)時，控(kong)制(zhi)部216確定(ding)送(song)電(dian)(dian)電(dian)(dian)力(li)大于(yu)(yu)充電(dian)(dian)必需(xu)的(de)(de)(de)(de)最小(xiao)電(dian)(dian)力(li)值，并且將(jiang)用于(yu)(yu)使供電(dian)(dian)電(dian)(dian)力(li)減小(xiao)一(yi)(yi)個等(deng)級的(de)(de)(de)(de)請求通(tong)(tong)知給饋電(dian)(dian)裝置(zhi)1(控(kong)制(zhi)部112)側(ce)。換句話說(shuo)，控(kong)制(zhi)部216向(xiang)饋電(dian)(dian)裝置(zhi)1側(ce)發送(song)必需(xu)送(song)電(dian)(dian)電(dian)(dian)力(li)降低一(yi)(yi)個等(deng)級的(de)(de)(de)(de)請求指(zhi)令(步(bu)驟s110)。這(zhe)個通(tong)(tong)知(必需(xu)送(song)電(dian)(dian)電(dian)(dian)力(li)降低一(yi)(yi)個等(deng)級的(de)(de)(de)(de)請求指(zhi)令)也是利用與饋電(dian)(dian)裝置(zhi)1的(de)(de)(de)(de)通(tong)(tong)信來(lai)進行的(de)(de)(de)(de)。應注意(yi)，流程此(ci)后返(fan)回到(dao)上述(shu)的(de)(de)(de)(de)步(bu)驟s102。

另一方面，當輸入電(dian)(dian)(dian)壓(ya)v1小(xiao)于(yu)(yu)閾值電(dian)(dian)(dian)壓(ya)vth1(v1<vth1，步驟s109：否)時，控(kong)制部(bu)216確定(ding)送電(dian)(dian)(dian)電(dian)(dian)(dian)力小(xiao)于(yu)(yu)充電(dian)(dian)(dian)必需的最小(xiao)電(dian)(dian)(dian)力值，并且(qie)將用于(yu)(yu)使送電(dian)(dian)(dian)電(dian)(dian)(dian)力增大一個等(deng)級的請(qing)求(qiu)通知(zhi)給饋電(dian)(dian)(dian)裝置1(控(kong)制部(bu)112)側。換句話(hua)說(shuo)，控(kong)制部(bu)216向饋電(dian)(dian)(dian)裝置1側發送必需送電(dian)(dian)(dian)電(dian)(dian)(dian)力上升一個等(deng)級的請(qing)求(qiu)指(zhi)令(步驟s111)。這個通知(zhi)(必需送電(dian)(dian)(dian)電(dian)(dian)(dian)力上升一個等(deng)級的請(qing)求(qiu)指(zhi)令)也(ye)是利用與饋電(dian)(dian)(dian)裝置1的通信來進(jin)行的。應注(zhu)意，流程(cheng)此后返(fan)回到(dao)上述(shu)的步驟s102。

以這樣的方(fang)式，在基于送電(dian)電(dian)力進行對電(dian)池214充(chong)電(dian)的充(chong)電(dian)期

備2a和(he)電(dian)(dian)子(zi)設(she)備2b中(zhong)的(de)各者向饋(kui)電(dian)(dian)裝(zhuang)置1側通知用于(yu)增大送電(dian)(dian)電(dian)(dian)力的(de)請求。即(ji)使(shi)(shi)如上所述(shu)地在充電(dian)(dian)期間內送電(dian)(dian)電(dian)(dian)力被減小和(he)抑制(zhi)成低電(dian)(dian)力，上述(shu)方式仍使(shi)(shi)得(de)饋(kui)電(dian)(dian)裝(zhuang)置1側增大供電(dian)(dian)電(dian)(dian)力。因此，在電(dian)(dian)子(zi)設(she)備2a和(he)2b的(de)各者中(zhong)，這使(shi)(shi)得(de)能(neng)夠容易地借助(zhu)于(yu)送電(dian)(dian)電(dian)(dian)力來確(que)保設(she)備自身啟動所需的(de)電(dian)(dian)力。

(饋電(dian)(dian)裝置1中的送電(dian)(dian)控(kong)制示例)

另一方(fang)面，圖10在(zai)(zai)流程(cheng)圖中(zhong)圖示了饋電(dian)(dian)裝置1中(zhong)的(de)(de)控(kong)(kong)制(zhi)部112的(de)(de)具體送電(dian)(dian)控(kong)(kong)制(zhi)示例(li)(充電(dian)(dian)期間內的(de)(de)送電(dian)(dian)控(kong)(kong)制(zhi)示例(li))。在(zai)(zai)送電(dian)(dian)控(kong)(kong)制(zhi)示例(li)中(zhong)，首先(xian)，在(zai)(zai)送電(dian)(dian)部110中(zhong)執行正常的(de)(de)送電(dian)(dian)操作(zuo)(傳(chuan)送100％的(de)(de)送電(dian)(dian)電(dian)(dian)力的(de)(de)操作(zuo))(步驟s201)。

接著，控制(zhi)部(bu)112判斷(duan)是否(fou)接收到來自(zi)電(dian)子(zi)設備(bei)2a和2b中各者(zhe)(控制(zhi)部(bu)216)側的預(yu)定(ding)指令(ling)(是否(fou)為(wei)特(te)定(ding)請求提供通知(zhi))(步(bu)驟(zou)s202)。在這里，當判定(ding)沒有接收到指令(ling)(步(bu)驟(zou)s202：否(fou))時，重(zhong)復步(bu)驟(zou)s202。

另一方面，一旦判(pan)定接收(shou)到(dao)指(zhi)(zhi)令(步驟(zou)(zou)s202：是)，控制部(bu)112隨后就通過對指(zhi)(zhi)令的內容進行解碼來識(shi)別(bie)指(zhi)(zhi)令的內容(步驟(zou)(zou)s203)。其后，控制部(bu)112判(pan)斷(duan)是否(fou)完(wan)成(cheng)(cheng)對電池214的充電(是否(fou)接收(shou)到(dao)上述的充電完(wan)成(cheng)(cheng)指(zhi)(zhi)令)(步驟(zou)(zou)s204)。

在這(zhe)里，一旦判定完成了(le)充(chong)電(dian)(dian)(dian)(步驟s204：是)，控(kong)制部(bu)112隨后就執行送(song)(song)電(dian)(dian)(dian)控(kong)制，以停止(zhi)(zhi)送(song)(song)電(dian)(dian)(dian)部(bu)110的送(song)(song)電(dian)(dian)(dian)操作(步驟s205)。這(zhe)防(fang)止(zhi)(zhi)了(le)對電(dian)(dian)(dian)子設備2a和2b的無用的(不必(bi)要的)送(song)(song)電(dian)(dian)(dian)(充(chong)電(dian)(dian)(dian))，從而避免由(you)于剩余的送(song)(song)電(dian)(dian)(dian)電(dian)(dian)(dian)力而造成的熱(re)等(deng)。然后完成了(le)圖10所示的充(chong)電(dian)(dian)(dian)期間內(nei)的由(you)控(kong)制部(bu)112進行的送(song)(song)電(dian)(dian)(dian)控(kong)制。

另一(yi)方面(mian)，一(yi)旦判定還沒有完成充(chong)電(dian)(步驟s204：否)，控制部112隨后就基于指令的(de)內(nei)容(上述的(de)啟(qi)動狀態信(xin)息(xi))判斷電(dian)子(zi)設(she)備(bei)(電(dian)子(zi)設(she)備(bei)2a或電(dian)子(zi)設(she)備(bei)2b中的(de)負載22)是否被啟(qi)動(步驟s206)。

在(zai)這里(li)，一旦判定電(dian)(dian)子設(she)備(負載)被啟動(步驟s206：是)，控制(zhi)部(bu)112隨(sui)后(hou)就控制(zhi)送(song)(song)電(dian)(dian)電(dian)(dian)力(li)(li)以使送(song)(song)電(dian)(dian)電(dian)(dian)力(li)(li)達到設(she)備側要求的(de)(de)(de)(de)(在(zai)上(shang)(shang)述的(de)(de)(de)(de)必(bi)(bi)需送(song)(song)電(dian)(dian)電(dian)(dian)力(li)(li)請求指令中(zhong)所要求的(de)(de)(de)(de))啟動所必(bi)(bi)需的(de)(de)(de)(de)電(dian)(dian)力(li)(li)值。因(yin)此(ci)，送(song)(song)電(dian)(dian)部(bu)110進(jin)行(xing)基(ji)于這樣的(de)(de)(de)(de)必(bi)(bi)需的(de)(de)(de)(de)電(dian)(dian)力(li)(li)值的(de)(de)(de)(de)送(song)(song)電(dian)(dian)(步驟s207)。應(ying)注意，流程隨(sui)后(hou)返回至上(shang)(shang)述的(de)(de)(de)(de)步驟s202。

另(ling)一(yi)方(fang)面，一(yi)旦(dan)判定(ding)電(dian)(dian)(dian)(dian)子設備(負(fu)載22)沒有(you)被(bei)啟動(dong)(步(bu)驟s206：否(fou))，控制(zhi)部112隨后就(jiu)基于指(zhi)(zhi)令(ling)(ling)的(de)(de)(de)內(nei)容判斷是(shi)否(fou)提供(gong)了送電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)力(li)(li)降低一(yi)個(ge)等級(ji)的(de)(de)(de)請(qing)求(步(bu)驟s208)。換(huan)句話說，判斷是(shi)否(fou)接收(shou)到(dao)上(shang)述(shu)的(de)(de)(de)必需(xu)送電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)力(li)(li)降低一(yi)個(ge)等級(ji)的(de)(de)(de)請(qing)求指(zhi)(zhi)令(ling)(ling)指(zhi)(zhi)令(ling)(ling)，或(huo)是(shi)否(fou)接收(shou)到(dao)上(shang)述(shu)的(de)(de)(de)必需(xu)送電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)力(li)(li)上(shang)升一(yi)個(ge)等級(ji)的(de)(de)(de)請(qing)求指(zhi)(zhi)令(ling)(ling)。

在(zai)這里(li)，一(yi)旦判定(ding)提供了送(song)電(dian)電(dian)力(li)降(jiang)低(di)一(yi)個(ge)(ge)等(deng)(deng)(deng)級(ji)的請求(一(yi)旦判定(ding)接收到必需送(song)電(dian)電(dian)力(li)降(jiang)低(di)一(yi)個(ge)(ge)等(deng)(deng)(deng)級(ji)的請求指(zhi)令(ling))(步(bu)驟s208：是)，控制部(bu)(bu)112就控制送(song)電(dian)電(dian)力(li)以使送(song)電(dian)電(dian)力(li)減小一(yi)個(ge)(ge)等(deng)(deng)(deng)級(ji)。因此，送(song)電(dian)部(bu)(bu)110進行基(ji)于減小了一(yi)個(ge)(ge)等(deng)(deng)(deng)級(ji)的送(song)電(dian)電(dian)力(li)的送(song)電(dian)(步(bu)驟s209)。應注意，流程隨后返回到上(shang)述的步(bu)驟s202。

另一(yi)方面，一(yi)旦判定沒(mei)有提供送(song)(song)電(dian)電(dian)力(li)(li)降低一(yi)個(ge)(ge)等級(ji)的請求(接(jie)收(shou)到必需(xu)送(song)(song)電(dian)電(dian)力(li)(li)上(shang)升一(yi)個(ge)(ge)等級(ji)的請求指令(ling))(步(bu)驟(zou)s208：否)，控制部(bu)112就控制送(song)(song)電(dian)電(dian)力(li)(li)以使送(song)(song)電(dian)電(dian)力(li)(li)增大(da)一(yi)個(ge)(ge)等級(ji)。因此(ci)，送(song)(song)電(dian)部(bu)110進行基于增大(da)了一(yi)個(ge)(ge)等級(ji)的送(song)(song)電(dian)電(dian)力(li)(li)的送(song)(song)電(dian)(步(bu)驟(zou)s210)。應注意，流程隨(sui)后返回(hui)至上(shang)述的步(bu)驟(zou)s202。

以(yi)這(zhe)樣的(de)(de)方式，當具(ju)有電(dian)(dian)(dian)(dian)池(chi)214的(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)設備(電(dian)(dian)(dian)(dian)子(zi)(zi)設備2a或(huo)電(dian)(dian)(dian)(dian)子(zi)(zi)設備2b)在(zai)(zai)基于送(song)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)力(li)進(jin)行對電(dian)(dian)(dian)(dian)池(chi)214充(chong)電(dian)(dian)(dian)(dian)的(de)(de)充(chong)電(dian)(dian)(dian)(dian)期(qi)間內被啟動時，控制送(song)電(dian)(dian)(dian)(dian)操作以(yi)增大(da)送(song)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)力(li)。這(zhe)使得即使如上所述(shu)地在(zai)(zai)充(chong)電(dian)(dian)(dian)(dian)期(qi)間內送(song)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)力(li)被減小和(he)抑制成(cheng)低電(dian)(dian)(dian)(dian)力(li)，在(zai)(zai)電(dian)(dian)(dian)(dian)子(zi)(zi)設備2a和(he)2b的(de)(de)各者中仍能夠(gou)容易地借助于送(song)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)力(li)確保設備自身(shen)啟動所需的(de)(de)電(dian)(dian)(dian)(dian)力(li)。

如(ru)上(shang)所述，在本(ben)實施例中，當具有電(dian)(dian)(dian)池(chi)214的(de)(de)(de)電(dian)(dian)(dian)子設備(電(dian)(dian)(dian)子設備2a或電(dian)(dian)(dian)子設備2b)在基于(yu)送(song)電(dian)(dian)(dian)電(dian)(dian)(dian)力(li)(li)進行對電(dian)(dian)(dian)池(chi)214充(chong)電(dian)(dian)(dian)的(de)(de)(de)充(chong)電(dian)(dian)(dian)期間(jian)內(nei)(nei)被(bei)(bei)啟動(dong)時(shi)，控(kong)制部112控(kong)制送(song)電(dian)(dian)(dian)操作以增(zeng)大送(song)電(dian)(dian)(dian)電(dian)(dian)(dian)力(li)(li)。此外，當在這樣的(de)(de)(de)充(chong)電(dian)(dian)(dian)期間(jian)內(nei)(nei)設備自身(電(dian)(dian)(dian)子設備2a或電(dian)(dian)(dian)子設備2b)被(bei)(bei)啟動(dong)時(shi)，控(kong)制部216將用于(yu)增(zeng)大送(song)電(dian)(dian)(dian)電(dian)(dian)(dian)力(li)(li)的(de)(de)(de)請求通(tong)知給(gei)饋電(dian)(dian)(dian)裝(zhuang)(zhuang)置(zhi)1側。這使(shi)得(de)即使(shi)在充(chong)電(dian)(dian)(dian)期間(jian)內(nei)(nei)送(song)電(dian)(dian)(dian)電(dian)(dian)(dian)力(li)(li)被(bei)(bei)減(jian)小和抑(yi)制成低電(dian)(dian)(dian)力(li)(li)，仍使(shi)饋電(dian)(dian)(dian)裝(zhuang)(zhuang)置(zhi)1側增(zeng)大送(song)電(dian)(dian)(dian)電(dian)(dian)(dian)力(li)(li)。因此，使(shi)得(de)在電(dian)(dian)(dian)子設備2a和2b的(de)(de)(de)各(ge)者中能夠容易地(di)借(jie)助于(yu)送(song)電(dian)(dian)(dian)電(dian)(dian)(dian)力(li)(li)確保(bao)設備自身啟動(dong)所需(xu)的(de)(de)(de)電(dian)(dian)(dian)力(li)(li)。因此，當進行利(li)(li)用磁(ci)場的(de)(de)(de)電(dian)(dian)(dian)力(li)(li)輸(shu)送(song)時(shi)，能夠提高(gao)用戶的(de)(de)(de)便利(li)(li)性。

應注意，在本(ben)實施例中(zhong)，超過負(fu)載(zai)22的(de)啟動(dong)必需最大電(dian)力(li)的(de)送電(dian)電(dian)力(li)(包含與電(dian)池214中(zhong)的(de)充(chong)電(dian)電(dian)力(li)的(de)組合)是控制(zhi)部112和216中(zhong)各者的(de)控制(zhi)的(de)條件。因此，當不(bu)滿足這(zhe)樣的(de)電(dian)力(li)平(ping)衡時，根(gen)據電(dian)池214的(de)剩(sheng)余電(dian)量，在啟動(dong)負(fu)載(zai)22時等可以(yi)優選(xuan)限(xian)制(zhi)(無(wu)效(xiao)化(hua))負(fu)載(zai)22的(de)一部分功能。這(zhe)是因為(wei)：在沒有(you)這(zhe)樣的(de)限(xian)制(zhi)(無(wu)效(xiao)化(hua))的(de)情況下，電(dian)池214的(de)充(chong)電(dian)電(dian)力(li)逐漸減小。

[變型例]

上面已經參照實施例說明了本(ben)發(fa)明的技術(shu)，但(dan)是本(ben)發(fa)明不限于這(zhe)樣的實施例且可以進(jin)行各(ge)種變(bian)型。

例如(ru)，在上述(shu)的(de)(de)實(shi)施例中(zhong)，已經使(shi)用(yong)(yong)(yong)各(ge)種線(xian)(xian)(xian)(xian)圈(quan)(quan)(送電線(xian)(xian)(xian)(xian)圈(quan)(quan)和(he)受電線(xian)(xian)(xian)(xian)圈(quan)(quan))進行說明，但(dan)是各(ge)種類型(xing)的(de)(de)構(gou)造可以用(yong)(yong)(yong)作這些(xie)線(xian)(xian)(xian)(xian)圈(quan)(quan)的(de)(de)構(gou)造(形(xing)(xing)(xing)狀(zhuang))。換句(ju)話(hua)說，每個線(xian)(xian)(xian)(xian)圈(quan)(quan)可以具(ju)有(you)例如(ru)如(ru)下的(de)(de)形(xing)(xing)(xing)狀(zhuang)：螺(luo)(luo)(luo)旋形(xing)(xing)(xing)狀(zhuang)、環路(lu)(lu)形(xing)(xing)(xing)狀(zhuang)、使(shi)用(yong)(yong)(yong)磁性物質的(de)(de)條形(xing)(xing)(xing)形(xing)(xing)(xing)狀(zhuang)、螺(luo)(luo)(luo)旋線(xian)(xian)(xian)(xian)圈(quan)(quan)被折疊成(cheng)兩層的(de)(de)α繞線(xian)(xian)(xian)(xian)形(xing)(xing)(xing)狀(zhuang)、具(ju)有(you)更多層的(de)(de)螺(luo)(luo)(luo)旋形(xing)(xing)(xing)狀(zhuang)以及繞線(xian)(xian)(xian)(xian)在厚度方(fang)向(xiang)上被卷繞的(de)(de)垂(chui)直螺(luo)(luo)(luo)旋形(xing)(xing)(xing)狀(zhuang)等(deng)。此外，每個線(xian)(xian)(xian)(xian)圈(quan)(quan)不僅可以是使(shi)用(yong)(yong)(yong)具(ju)有(you)導(dao)電性的(de)(de)線(xian)(xian)(xian)(xian)材構(gou)成(cheng)的(de)(de)繞線(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)圈(quan)(quan)，而且(qie)可以是具(ju)有(you)導(dao)電性的(de)(de)且(qie)使(shi)用(yong)(yong)(yong)例如(ru)印刷電路(lu)(lu)板和(he)柔性印刷電路(lu)(lu)板等(deng)構(gou)成(cheng)的(de)(de)圖案線(xian)(xian)(xian)(xian)圈(quan)(quan)。

此外，在上述的(de)實施例(li)(li)中，已經將電(dian)(dian)子(zi)設(she)備說明為饋電(dian)(dian)對象設(she)備的(de)例(li)(li)子(zi)，但(dan)是(shi)饋電(dian)(dian)對象設(she)備不限(xian)于此且可(ke)以是(shi)電(dian)(dian)子(zi)設(she)備以外的(de)任何類型(xing)的(de)饋電(dian)(dian)對象設(she)備(例(li)(li)如，諸如電(dian)(dian)車等車輛)。

此(ci)外，在上(shang)述(shu)(shu)(shu)的(de)(de)(de)(de)實施例中(zhong)(zhong)，已(yi)經具(ju)體地說(shuo)明(ming)了饋電(dian)(dian)(dian)(dian)(dian)裝置和(he)電(dian)(dian)(dian)(dian)(dian)子(zi)設(she)(she)備(bei)(bei)的(de)(de)(de)(de)每個組件。然(ran)而(er)(er)，不必要設(she)(she)置所有(you)的(de)(de)(de)(de)組件，或還可(ke)以(yi)(yi)(yi)設(she)(she)置其它(ta)組件。例如，可(ke)以(yi)(yi)(yi)在饋電(dian)(dian)(dian)(dian)(dian)裝置和(he)/或電(dian)(dian)(dian)(dian)(dian)子(zi)設(she)(she)備(bei)(bei)中(zhong)(zhong)提(ti)供(gong)通信(xin)功(gong)能(neng)、執行(xing)(xing)某種(zhong)類(lei)型的(de)(de)(de)(de)控(kong)(kong)制的(de)(de)(de)(de)功(gong)能(neng)、顯示功(gong)能(neng)、驗證次級側設(she)(she)備(bei)(bei)的(de)(de)(de)(de)功(gong)能(neng)、檢(jian)測(ce)諸如異種(zhong)金(jin)屬等(deng)(deng)混(hun)合物的(de)(de)(de)(de)功(gong)能(neng)以(yi)(yi)(yi)及諸如此(ci)類(lei)的(de)(de)(de)(de)功(gong)能(neng)。此(ci)外，可(ke)以(yi)(yi)(yi)僅在預定(ding)(ding)的(de)(de)(de)(de)條件下進(jin)(jin)行(xing)(xing)上(shang)述(shu)(shu)(shu)實施例中(zhong)(zhong)的(de)(de)(de)(de)送(song)(song)電(dian)(dian)(dian)(dian)(dian)控(kong)(kong)制(當作為饋電(dian)(dian)(dian)(dian)(dian)對象設(she)(she)備(bei)(bei)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)設(she)(she)備(bei)(bei)在充(chong)電(dian)(dian)(dian)(dian)(dian)期(qi)間(jian)內(nei)被啟(qi)(qi)(qi)動(dong)時(shi)增大送(song)(song)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)力的(de)(de)(de)(de)控(kong)(kong)制)，而(er)(er)不是在啟(qi)(qi)(qi)動(dong)電(dian)(dian)(dian)(dian)(dian)子(zi)設(she)(she)備(bei)(bei)時(shi)一律進(jin)(jin)行(xing)(xing)這樣的(de)(de)(de)(de)送(song)(song)電(dian)(dian)(dian)(dian)(dian)控(kong)(kong)制。例如，在進(jin)(jin)行(xing)(xing)事先規定(ding)(ding)的(de)(de)(de)(de)預定(ding)(ding)順序(操作)的(de)(de)(de)(de)情況(kuang)(kuang)下，即使當電(dian)(dian)(dian)(dian)(dian)子(zi)設(she)(she)備(bei)(bei)被啟(qi)(qi)(qi)動(dong)時(shi)也(ye)可(ke)以(yi)(yi)(yi)禁止上(shang)述(shu)(shu)(shu)的(de)(de)(de)(de)送(song)(song)電(dian)(dian)(dian)(dian)(dian)控(kong)(kong)制的(de)(de)(de)(de)執行(xing)(xing)。換(huan)句話說(shuo)，例如，當在上(shang)述(shu)(shu)(shu)的(de)(de)(de)(de)預定(ding)(ding)序列以(yi)(yi)(yi)外的(de)(de)(de)(de)任(ren)何情況(kuang)(kuang)下啟(qi)(qi)(qi)動(dong)電(dian)(dian)(dian)(dian)(dian)子(zi)設(she)(she)備(bei)(bei)時(shi)(諸如當用(yong)戶通過按壓電(dian)(dian)(dian)(dian)(dian)子(zi)設(she)(she)備(bei)(bei)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)源按鈕來啟(qi)(qi)(qi)動(dong)電(dian)(dian)(dian)(dian)(dian)子(zi)設(she)(she)備(bei)(bei)時(shi)等(deng)(deng))，可(ke)以(yi)(yi)(yi)執行(xing)(xing)上(shang)述(shu)(shu)(shu)的(de)(de)(de)(de)送(song)(song)電(dian)(dian)(dian)(dian)(dian)控(kong)(kong)制。

此(ci)外，上(shang)面(mian)已經通過主要采用饋電(dian)系(xi)統中設置有多(duo)個(ge)(兩個(ge)或以上(shang))電(dian)子設備的(de)情況作為示例(li)說明(ming)了實施例(li)。然而，不限(xian)于(yu)這種情況，饋電(dian)系(xi)統中可以僅(jin)有一個(ge)電(dian)子設備。

此(ci)外(wai)，上面(mian)已經通過采用(yong)(yong)用(yong)(yong)于(yu)(yu)諸如移動電話等的小型電子(zi)(zi)設備(bei)(ce設備(bei))的充(chong)電托(tuo)盤(pan)作(zuo)為(wei)饋電裝置(zhi)的示(shi)例說明了實施(shi)例。然而，饋電裝置(zhi)不限于(yu)(yu)這樣的家用(yong)(yong)充(chong)電托(tuo)盤(pan)，且可以應(ying)用(yong)(yong)于(yu)(yu)各(ge)種類型電子(zi)(zi)設備(bei)的電池充(chong)電器(qi)。此(ci)外(wai)，對(dui)于(yu)(yu)饋電裝置(zhi)而言，不一定是托(tuo)盤(pan)且可以是例如所謂的托(tuo)架(jia)等電子(zi)(zi)設備(bei)用(yong)(yong)支架(jia)。

(使(shi)用電場進行非接觸式電力輸(shu)送的(de)饋電系統的(de)示例)

此(ci)外(wai)，已經通過采用如下(xia)(xia)的(de)(de)(de)非接觸式(shi)饋(kui)(kui)電系(xi)統的(de)(de)(de)情況(kuang)作為(wei)示(shi)例提供了上述實施例：該非接觸式(shi)饋(kui)(kui)電系(xi)統利用磁(ci)場(chang)(chang)進(jin)行從(cong)作為(wei)初級(ji)(ji)側(ce)(ce)(ce)設(she)備(bei)(bei)的(de)(de)(de)饋(kui)(kui)電裝置(zhi)到作為(wei)次級(ji)(ji)側(ce)(ce)(ce)設(she)備(bei)(bei)的(de)(de)(de)電子設(she)備(bei)(bei)的(de)(de)(de)非接觸式(shi)電力輸送(song)(饋(kui)(kui)電)。但本發明不限于(yu)此(ci)。換句話(hua)說，本發明的(de)(de)(de)內(nei)容也(ye)可(ke)應用于(yu)利用電場(chang)(chang)(電場(chang)(chang)耦合)進(jin)行從(cong)作為(wei)初級(ji)(ji)側(ce)(ce)(ce)設(she)備(bei)(bei)的(de)(de)(de)饋(kui)(kui)電裝置(zhi)到作為(wei)次級(ji)(ji)側(ce)(ce)(ce)設(she)備(bei)(bei)的(de)(de)(de)電子設(she)備(bei)(bei)的(de)(de)(de)非接觸式(shi)電力輸送(song)的(de)(de)(de)饋(kui)(kui)電系(xi)統。在這種情況(kuang)下(xia)(xia)，能夠獲得類似于(yu)上述實施例的(de)(de)(de)效(xiao)果(guo)。
