Abstract
An energy storage system and a method for controlling the energy storage system, includes a plurality of energy storage units. The energy storage unit includes a plurality of battery cells, a plurality of balancing units, a voltage conversion unit, a first switch, a second switch, and a control unit. The control unit is configured to detect fault cases of the plurality of battery cells, and control open and closed states of the first switch and the second switch. According to the application, it can be ensured that each energy storage unit in the energy storage system can continuously work when a battery cell is faulty and when state of charge balance between battery cells is implemented, thereby greatly improving reliability of the energy storage system with low costs.
