제어부(70)는 전력 사용후 배터리모듈들(11, 12, 13, 14) 상호간 전압 불균형을 해소할 수 있게 개별배터리관리부들(21, 22, 23, 24)의 동작을 각각 제어하며, 배터리모듈들(11, 12, 13, 14)을 각각 독립적으로 충전시킬 수 있다. The controller 70 controls the operation of the individual battery management units 21, 22, 23, and 24 to resolve voltage imbalance between the battery modules 11, 12, 13, and 14 after power is used, respectively, and the battery module s (11, 12, 13, 14) can be charged independently of each other.

일 예로, 제1개별출력부(31)를 사용한 후에 제3개별출력부를 사용하고자 하면, 제1개별출력부(31)에 전력을 공급하는 제1배터리모듈(11, 12, 13, 14)과 나머지 제2배터리모듈(11, 12, 13, 14) 내지 제3배터리모듈(11, 12, 13, 14) 상호간 전압 불균형이 발생하고, 제1배터리모듈(11, 12, 13, 14)의 용량 감소로 인해 제3개별출력부를 효율적으로 사용하기가 어렵다. 따라서, 각 배터리모듈(11, 12, 13, 14)의 방전 정보를 모니터링하고, 이 정보를 제어부에서 받아 용량이 감소한 해당 배터리모듈(11, 12, 13, 14)을 개별 충전함으로써 추후 전기기기를 사용시 안정적으로 전력을 공급할 수 있다.For example, if you want to use the third individual output unit after using the first individual output unit 31, the first battery module 11, 12, 13, 14 supplying power to the first individual output unit 31 and Voltage imbalance occurs between the remaining second battery modules (11, 12, 13, 14) to third battery modules (11, 12, 13, 14), and the capacity of the first battery modules (11, 12, 13, 14) Due to the reduction, it is difficult to efficiently use the third individual output unit. Therefore, by monitoring the discharge information of each battery module (11, 12, 13, 14), and receiving this information from the control unit, the corresponding battery module (11, 12, 13, 14) whose capacity is reduced is individually charged, so that the electric device can be stored later. Power can be supplied stably during use.
