A cell balancing device 100 is provided with: a capacitance adjusting circuit 10 which includes a plurality of series-connected switch elements 11 and resistors 12 connected in parallel with battery cells 210, and which is capable of adjusting the capacitance of each battery cell 210; a processor 40; and a watchdog unit 60 which monitors the processor 40 and resets the processor 40 if an abnormality arises in the processor 40. The processor 40 transitions to a sleep state when a vehicle ignition is turned off, and adjusts the capacitance of each battery cell 210 in the sleep state by controlling the switch elements 11, and when adjusting the capacitances of the battery cells 210, the processor 40 sets the number of battery cells 210 to be discharged simultaneously to a prescribed number such that a current flowing through the processor 40 is less than a prescribed value.

    电池均衡装置(100)包括:容量调整电路(10),其包含多个与各电池单元(210)并联连接的、串联连接的开关元件(11)和电阻(12),能够调整各电池单元(210)的容量;处理器(40);以及看门狗部(60),其监视处理器(40),在处理器(40)处于异常情况时使处理器(40)复位。处理器(40)随着车辆的点火装置关闭而转变为睡眠状态,且在睡眠状态下对开关元件(11)进行控制,来调整各电池单元(210)的容量,处理器(40)在调整各电池单元(210)的容量时,将同时放电的电池单元(210)的个数设定为规定数,使得流经处理器(40)的电流低于规定值。
