Abstract

本申请公开充电补偿电路(100)包括第一开关单元(20)、第二开关单元(30)及控制单元(40)。第一开关单元(20)与第二电池单元(901b)相连接；第二开关单元(30)与第一电池单元(901a)相连接。当所述电池包(900)的充电电流达到预设充电电流时，控制单元(40)控制第二开关单元(30)闭合，并通过第二充电补偿电路对处于相对不饱和状态的第一电池单元(901a)进行充电补偿；或控制第一开关单元(20)闭合，并通过第一充电补偿电路对处于相对不饱和状态的所述第二电池单元(901b)进行补偿充电。本申请还提供一种电子装置(800)。本申请能够使得串联的第一电池单元(901a)和第二电池单元(901b)均达到充电饱和状态。
