The invention discloses a multi-branch battery system high-voltage framework for a heavy truck, a control method, electronic equipment and a storage medium. The multi-branch battery system high-voltage framework comprises a plurality of battery branches and a whole truck all-in-one circuit, the battery branch comprises a battery pack, and a power supply loop, a high-voltage acquisition unit, a signal acquisition unit and a battery management unit are arranged in the battery pack. The whole vehicle all-in-one circuit comprises battery positive electrodes matched with the battery branches in number, battery negative electrodes matched with the battery branches in number, a charging positive electrode, a charging negative electrode, a motor port and a main battery management unit. According to the method, the voltage difference between multiple branches is solved through two methods including balance before discharging and charge balance, the problem of circulation between the branches is effectively solved, in addition, the problem of circulation between the branches and the problem of the voltage difference between the branches are considered in a combined mode, the method is more practical, the fault tolerance of the whole vehicle function is improved, and the cost of the whole vehicle is reduced. A single branch can be controlled to work, a high-voltage box structure is omitted, and the integration level of the whole vehicle is improved.

    本发明公开了一种重卡用多支路电池系统高压架构、控制方法、电子设备及存储介质,包括多个电池支路,整车多合一电路;所述电池支路包括:电池包,所述电池包内设置有电源回路,高压采集单元,信号采集单元,电池管理单元。所述整车多合一电路包括:与电池支路数量相匹配的电池正极,与电池支路数量相匹配的电池负极,充电正极,充电负极,电机端口,主电池管理单元。本发明通过两种方法解决多支路间电压差,包括放电前均衡和充电均衡,有效解决每个支路间的环流问题,另外,将解决每个支路间环流问题和多支路间电压差的问题进行了结合考虑,更具有实用性,提高了整车功能容错性,可以控制单支路进行工作,取消了高压盒结构,提高了整车集成度。
