評述:

CN3705是PWM減壓形勢鋰(li)離子動(dong)力干蓄(xu)電(dian)池箱(xiang)或磷(lin)酸鐵鋰(li)離子動(dong)力干蓄(xu)電(dian)池箱(xiang)進行(xing)快充辦集成化用電(dian)線路，自力對單節(jie)或多節(jie)鋰(li)離子動(dong)力干蓄(xu)電(dian)池箱(xiang)或磷(lin)酸鐵鋰(li)離子動(dong)力干蓄(xu)電(dian)池箱(xiang)進行(xing)快充停(ting)掉(diao)主動(dong)權辦，遵循封(feng)裝類型外觀小，基本(ben)元電(dian)器(qi)元件少和根據(ju)簡短等優勢。

CN3705具備恒流和恒壓充電情勢，很是合適鋰電池或磷酸鐵鋰電池的充電。在恒壓充電情勢，恒壓充電電壓由內部電阻分壓收集設置；在恒流充電情勢，充電電流經由過程一個內部電阻設置。

其他副作用構成輸出的(de)低(di)電(dian)流值鎖存，電(dian)板水溫監測器，電(dian)板端過(guo)壓掩(yan)體和快充運行唆使等(deng)。
