The invention relates to the technical field of electric vehicles, and discloses a control method and device for a range extending system of an electric crane, the range extending system and a medium, and the method comprises the steps that after a high voltage increasing instruction of a whole vehicle controller is received, battery state information of each battery is obtained; screening the plurality of batteries based on the battery state information, and determining a target power supply battery; and controlling the target power supply battery to be connected with the motor controller so as to supply power to a motor of the electric crane through the motor controller. After the whole vehicle controller issues the high-voltage instruction, the battery management unit is used for obtaining the battery state information of each battery, the appropriate target power supply battery is screened out and controlled to be connected with the motor controller, a large-electric-quantity battery with redundant electric quantity and high cost does not need to be arranged for the electric crane, and the vehicle purchasing cost is reduced. The target power supply battery is used for supplying power to the motor of the electric crane, range-extending work is achieved, and the requirements of different clients for different application scenes can be met.
本发明涉及电动车辆技术领域,公开了电动起重机增程系统的控制方法、装置、增程系统及介质,方法包括:在接收到整车控制器的上高压指令后,获取每个电池的电池状态信息;基于电池状态信息对多个电池进行筛选,确定目标供电电池;控制目标供电电池与电机控制器相连接,以通过电机控制器向电动起重机的电机进行供电。本发明在整车控制器下达上高压指令后,通过利用电池管理单元获取每个电池的电池状态信息,筛选出合适的目标供电电池并控制其与电机控制器相连接,无需为电动起重机设置电量冗余、成本较高的大电量电池,降低了购车成本。利用目标供电电池为电动起重机的电机进行供电,实现增程式工作,能满足不同客户不同应用场景的需求。
