Energy storage module, power supply system and control method of energy storage module

Abstract

The application discloses an energy storage module, a power supply system and a control method of the energy storage module. The energy storage module comprises a bidirectional DC / DC converter and an energy storage unit. The first end of the bidirectional DC / DC converter is connected with the energy storage unit. The control method comprises the following steps: when the load of a power module connected with the second end of the bidirectional DC / DC converter is in an idle state, the energy storage module is controlled to work in a charging mode, and the input current of the power module is compensated according to a specific condition by selecting a full-power compensation mode or a reduced-power compensation mode.
