Annular/serial charging pile power intelligent switching charging method and device and computer equipment

The invention relates to an annular/serial charging pile power intelligent switching charging method and device and computer equipment. The method comprises the steps that whether a target charging gun exists or not is detected, the required power of the target charging gun is larger than the charging power capable of being output by a target power module, and the target power module is connected with the target charging gun; and if the target charging gun exists, controlling all or part of the plurality of power supply modules to output charging power to the target power supply module from the power supply module directly connected with the target power supply module according to a preset power supply sequence, and the target power supply module supplies power to the target charging gun based on the charging power of the target power supply module and the charging power input by other power supply modules. By adopting the method, automatic switching can be performed according to the required power of each ch
