Dynamic equalization charging circuit of battery cell

The utility model relates to the technical field of batteries and particularly relates to the dynamic equalization charging circuit of a battery cell. According to the technical scheme of the utility model, the dynamic equalization charging circuit of the battery cell comprises a battery cell. One end of the battery cell is connected with a charging inductor L. The other end of the battery cell is electrically connected with one end of a controllable switch power device VT. The other end of the controllable switch power device VT is electrically connected with one end of a diode VD. The other end of the diode VD is electrically connected with one end of an energy-storage capacitor C. The charging processes of battery cells can be independently administrated, and the charging current/voltage can be controlled. In this way, all battery cells are enabled to work in an optimal state, so that the service life of battery cells is prolonged. Meanwhile, a faulted battery cell can be cut out, while the charging processes of all the other battery cells are not influenced at all. Therefore, the reliability of an entire battery pack is improved.
