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.
