The invention relates to a power supply loop control method and device and a power supply loop, and relates to the technical field of power supply. The power supply loop comprises a first battery pack, a second battery pack, a connection control element and a loop control element, the control method comprises the following steps: controlling the on-off state of each control element in the connection control elements, so that the first battery pack and the second battery pack are in different target connection states; according to a target control strategy corresponding to the target connection state, the working state of the loop control element in the time sequence is controlled; wherein the time point for controlling the on-off state of the control element is before the time point for controlling the loop control element. By using the control method of the power supply loop provided by the invention, the working states of the connection control element and the loop control element on the time sequence are defined after the connection control element is added, so that the high-voltage power-on and power-off process is smoothly completed.

    本公开涉及一种供电回路的控制方法、装置与供电回路,涉及供电技术领域。该供电回路包括:第一电池组、第二电池组、连接控制件与回路控制件;该控制方法包括:控制该连接控制件中各个控制件的开关状态,以使该第一电池组与该第二电池组处于不同的目标连接状态;以该目标连接状态对应的目标控制策略,控制该回路控制件在时序上的工作状态;其中,控制该控制件的开关状态的时间点位于控制该回路控制件的时间点之前。使用本公开提出的供电回路的控制方法,定义了增加连接控制件后,连接控制件与回路控制件在时序上的工作状态,以顺利完成高压上下电过程。
