Control circuit of energy storage system

Abstract

The utility model discloses a control circuit of an energy storage system. The control circuit of the energy storage system comprises a battery cell module, a control module and a reversing module, wherein the battery cell module, the control module and the reversing module are connected in sequence; the battery cell module comprises n modularized battery cell control units, and each modularized battery cell control unit comprises a battery cell, a first switch and a second switch; the cell is connected in series with the first switch and then connected in parallel with the second switch; n is a positive integer; the first first switch and the first second switch are connected to serve as a first end of the battery cell module, and the nth battery cell and the nth second switch are connected to serve as a second end of the battery cell module; the control module is in communication connection with the modular battery cell control unit and the reversing module, and the control module is used for controlling on or off of the first reversing switch, the second reversing switch, the third reversing switch and the fourth reversing switch. The utility model realizes the mixed use of new and old battery cells.
