The invention discloses a system and method for parallel battery charging. The battery management system is provided with a first charging circuit including a first switch to connect the first battery pack to a power source. The second charging circuit includes a second switch to connect the second battery pack to the power source, wherein the second charging circuit is arranged in parallel with the first charging circuit. The discharge circuit includes a discharge switch to connect the first battery pack and the second battery pack in series. The processor is programmed to: turn off the power-off switch; receiving an input indicative of a first battery voltage and a second battery voltage; closing the first switch and opening the second switch in response to the first battery voltage being less than the second battery voltage; and closing the first switch and closing the second switch in response to the first battery voltage being approximately equal to the second battery voltage.

    本申请公开了用于并行电池组充电的系统和方法。电池管理系统设置有包括第一开关的第一充电电路以将第一电池组连接到电源。第二充电电路包括第二开关以将第二电池组连接到电源,其中第二充电电路与第一充电电路并联地布置。放电电路包括放电开关以串联地连接第一电池组和第二电池组。处理器被编程为:断开放电开关;接收指示第一电池电压和第二电池电压的输入;响应于第一电池电压小于第二电池电压而闭合第一开关并断开第二开关;以及响应于第一电池电压近似等于第二电池电压而闭合第一开关并闭合第二开关。
