18650鋰電(dian)池充(chong)電(dian)方法??　　一(yi)、智能充(chong)電(dian):??這是(shi)目(mu)前認為幻想的(de)充(chong)電(dian)治理方法，遵守本節開(kai)頭所說的(de)充(chong)電(dian)算(suan)法，集成到小片(pian)IC中(zhong)，周(zhou)邊電(dian)路簡單，牢(lao)固堅(jian)固，如TP4054/4055/4056/4057、TP4002/5000、MAX1879等。該芯(xin)片(pian)的(de)重要特點(dian)是(shi)在判斷(duan)是(shi)否充(chong)斥時(shi)(shi)同時(shi)(shi)監督電(dian)壓跟電(dian)流，結束充(chong)電(dian)，或者充(chong)電(dian)電(dian)流小于(通常在50mA左(zuo)右)結束充(chong)電(dian)，充(chong)斥后完全結束，不(bu)涓流浮動充(chong)電(dian)，但隨時(shi)(shi)監督電(dian)壓，電(dian)池電(dian)壓降(jiang)落到一(yi)定值后開(kai)端充(chong)電(dian)。??

　　二、恒(heng)壓充(chong)(chong)電(dian)(dian)(dian):??該方法與一品種似(si)，恒(heng)壓實(shi)際上是限度壓力，設定比較正確的高壓，而后逝世亡其電(dian)(dian)(dian)壓，不(bu)起誓，江(jiang)湖人稱傻(sha)瓜充(chong)(chong)電(dian)(dian)(dian)，該充(chong)(chong)電(dian)(dian)(dian)器正確地反過來(lai)結束(shu)電(dian)(dian)(dian)壓，低反而保險，高反過來(lai)依附維(wei)護板，裸電(dian)(dian)(dian)池當初(chu)的手機(ji)全能充(chong)(chong)電(dian)(dian)(dian)跟手電(dian)(dian)(dian)直接充(chong)(chong)電(dian)(dian)(dian)很(hen)常見，這個充(chong)(chong)電(dian)(dian)(dian)器的本錢不(bu)到一元(yuan)，都(dou)是由劣(lie)質(zhi)整(zheng)機(ji)組合而成，淘寶零售價格不(bu)同(tong)，不(bu)能說(shuo)能用(yong)多少。??

　　三、恒(heng)(heng)流(liu)充(chong)電(dian):??該(gai)(gai)方法仍源于(yu)上一(yi)(yi)個跟上一(yi)(yi)個電(dian)路，但限度了高充(chong)電(dian)電(dian)流(liu)，恒(heng)(heng)流(liu)恒(heng)(heng)壓(ya)實際上是(shi)限流(liu)限壓(ya)，該(gai)(gai)電(dian)路比較盛(sheng)行，如南孚、鑫宇(yu)流(liu)，充(chong)斥后不完全截(jie)止，改為涓(juan)流(liu)浮充(chong)——當初長時光的小電(dian)流(liu)充(chong)電(dian)??

　　四(si)、高壓充(chong)電(dian):??該(gai)充(chong)電(dian)方法無把持電(dian)路，直接(jie)用5V電(dian)源頭(或串二管降壓)充(chong)電(dian)帶維(wei)護板的電(dian)池(chi)，完全依附(fu)維(wei)護板的高壓限度(du)。特點(dian)是開端時電(dian)流大，而后逐步降落，隨時浮動(dong)。
