How Energy Storage in EVs Supports the Grid
In traditional EV charging, the charging station draws power from the grid and charges the EV battery. Withbidirectional charging, the EV has an internal inverter that takes DC power from battery storage and converts it to AC power. The EV then sends power back to the grid. This is referred to as vehicle-to-grid (V2G) technology.
