Capacitor series circuit and energy storage system

Abstract

This utility model relates to the technical field of power supply circuits, mainly providing a capacitor series circuit and an energy storage system. The circuit includes a first capacitor, a first detection module, a first consumption module, a second capacitor, a second detection module, and a second consumption module. The first and second capacitors are connected in series. The first detection module is connected to both the first capacitor and the first consumption module. The second detection module is connected to both the second capacitor and the second consumption module. The first consumption module, the second consumption module, the first capacitor, and the second capacitor are also used to connect to a power supply. Both the first and second capacitors are used to receive and store the power supply voltage. The first and second detection modules are used to detect the voltage stored in the corresponding capacitors. When the stored voltage exceeds a preset voltage, the corresponding consumption module is controlled to start working, thereby consuming the voltage stored in the corresponding capacitor. This ensures that the two capacitors are in a voltage equalization state, improving the safety of the energy storage system.
