The invention provides a double-low-voltage lithium battery control system and method, and belongs to the technical field of lithium batteries. The system comprises two low-voltage lithium batteries and a double-battery controller; the low-voltage lithium battery comprises a lithium battery module and a lithium battery protection plate, the lithium battery module comprises one or more battery cells; the lithium battery protection board is used for collecting working state parameters of the lithium battery module, sending the working state parameters of the lithium battery module to the double-battery controller, receiving a charging and discharging instruction sent by the double-battery controller, and controlling the lithium battery module to charge and discharge based on the charging and discharging instruction; and the double-battery controller is used for generating a corresponding charging and discharging instruction based on the working state parameter of the lithium battery module. The working state parameters collected by the lithium battery protection board are received through the double-battery controller, the corresponding charging and discharging instruction is generated, the lithium battery protection board is controlled to charge the lithium battery module, and the technical problem that the cost is high due to the fact that an existing double-battery control scheme is complex is solved.

    本发明提供一种双低压锂电池控制系统及方法,属于锂电池技术领域,该系统包括:两块低压锂电池和双电池控制器;低压锂电池,包括:锂电池模组和锂电池保护板;锂电池模组包括一个或者多个电芯;锂电池保护板,用于采集锂电池模组的工作状态参数,并将锂电池模组的工作状态参数发送至双电池控制器,且接收双电池控制器发送的充放电指令,基于充放电指令控制锂电池模组进行充放电;双电池控制器,用于基于锂电池模组的工作状态参数,生成对应的充放电指令。本发明通过一个双电池控制器接收锂电池保护板采集的工作状态参数,生成对应的充放电指令,控制锂电池保护板对锂电池模组进行充电,解决了现有的双电池控制方案复杂导致的成本高的技术问题。
