The utility model can perform various types of energy storage and discharge working modes. The first is a grid-connected discharge working mode. Before use, the second bidirectional AC / DC module 5 needs to be connected to the power grid 7. The energy flow enters the first bidirectional AC / DC module 4 and the second bidirectional AC / DC module 5 through the battery pack 1, and then enters the power grid 7 through the first bidirectional AC / DC module 4 and the second bidirectional AC / DC module 5, completing the grid-connected discharge after connecting to the power grid 7. The second is an off-grid discharge working mode. The power grid 7 is connected to the load. The energy flow enters the first bidirectional AC / DC module 4 and the second bidirectional AC / DC module 5 through the battery pack 1, enters the power grid 7 through the first bidirectional AC / DC module 4 and the second bidirectional AC / DC module 5, and then enters the load through the power grid 7, thereby realizing charging of off-grid load equipment.
