When charging:

●Charging adopts switching constant current source, which has higher energy conversion efficiency than traditional linear constant current source;

●Energy flow direction: (power grid + energy generated by discharge equipment) → AC/DC two-way inverter power supply → constant current source module → battery

When discharging:

●Energy flow direction during discharge: battery→constant current source module→AC/DC two-way inverter power supply→battery→(discharging equipment + grid)

●When discharging, most of the energy will flow through the factory's AC bus to the charging equipment and other energy-consuming equipment (such as air conditioning, lighting, office equipment, etc.), and there is still excess energy that will be fed back to the grid.
