Abstract

This application pertains to the field of power electronics technology and provides a power supply circuit for a battery management system of an energy storage system, an energy storage valve, and an energy storage station. When an energy storage submodule (10) where the battery management system in the power supply circuit for the battery management system is located operates normally, a battery module (Bat) of the energy storage submodule (10) is selected to supply power to the battery management system. When the energy storage submodule (10) where the battery management system is located is bypassed, energy storage submodules (10') other than the energy storage submodule (10) where the battery management system is located are selected to supply power to the battery management system, thereby mitigating the issue of over-discharge in the battery module (Bat) of the bypassed energy storage submodule (10) due to the continuous consumption of the battery management system. Furthermore, all battery management systems within the energy storage submodule (10) are controlled to be powered by batteries of electric cabinets (100) where the battery management systems are located, allowing for the charge level uniformity of the electric cabinets (100) in the same energy storage submodule (10).
