鎳氫電池充電管理說明

DS2715非常適合于成本敏感的充電應用，鎳氫電池可(ke)(ke)(ke)(ke)以在(zai)(zai)系統(tong)內(nei)部(bu)，或(huo)在(zai)(zai)一個特殊的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)包內(nei)。它經(jing)過(guo)(guo)優化，可(ke)(ke)(ke)(ke)對1至(zhi)10個串(chuan)連(lian)鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)進行安全(quan)(quan)可(ke)(ke)(ke)(ke)靠的充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。DS2715具有一個內(nei)部(bu)增益模(mo)(mo)塊，可(ke)(ke)(ke)(ke)用(yong)(yong)(yong)作(zuo)比(bi)較器或(huo)控制充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的跨(kua)阻(zu)放(fang)大器。DS2715可(ke)(ke)(ke)(ke)配置(zhi)為(wei)開關(guan)型DC充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器、線性電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)調節器或(huo)開關(guan)模(mo)(mo)式電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)源。DS2715對深(shen)度放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)首先進行預調理，然后進入全(quan)(quan)速充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)模(mo)(mo)式。DS2715采用(yong)(yong)(yong)dT/dt技(ji)術中止(zhi)全(quan)(quan)速充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。需要外(wai)接一個熱(re)敏電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)來檢(jian)測dT/dt。溫度過(guo)(guo)高、溫度過(guo)(guo)低及(ji)過(guo)(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓檢(jian)測功能可(ke)(ke)(ke)(ke)防止(zhi)在(zai)(zai)不安全(quan)(quan)的環境條件下對電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)進行充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。用(yong)(yong)(yong)戶(hu)可(ke)(ke)(ke)(ke)選的充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)定時器適合于0.167°C至(zhi)2°C的充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)速率。快充(chong)、滿(man)充(chong)和充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)完成(cheng)等模(mo)(mo)式的整(zheng)合實現了(le)高度可(ke)(ke)(ke)(ke)靠、安全(quan)(quan)的鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)模(mo)(mo)式下DS2715進入低功耗睡眠狀態，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)向負載放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。
