Energy storage power supply, parallel control device for energy storage power supplies, and parallel control method for energy storage power supplies

Abstract

Provided are an energy storage power supply, a parallel control device for energy storage power supplies, and a parallel control method for energy storage power supplies. The energy storage power supply includes: a battery module, which is configured to store electric energy or output the electric energy; an inverter module electrically connected to the battery module, where the inverter module is configured to convert a direct current of the battery module into an alternating current; an output module electrically connected to the inverter module, where the output module is configured to output the alternating current after the inverter module is turned on; a communication module wirelessly communicated with another energy storage power supply; and a processor module electrically connected to the inverter module, the output module and the communication module, respectively, where the processor module is configured to control on-off of the output module. In the energy storage power supply, the parallel control device for energy storage power supplies, and the parallel control method for energy storage power supplies provided by embodiments of the present disclosure, when energy storage power supplies are connected in parallel, interference of a power line to a communication signal can be effectively reduced, thereby improving the parallel effect of energy storage power supplies; and the energy storage power supplies do not need to be provided with interfaces for connecting communication lines, thereby reducing the number of interfaces of the energy storage power supplies.
