What Is Bidirectional Charging? Understanding the Benefits for Both Drivers and Businesses

EV Connect

In one-directional charging, alternating current (AC) electricity is converted to direct current (DC) energy that’s stored in an EV battery to power the car. Vehicle to load (V2L) : This is probably the most common type of bidirectional charging available today. This can further reduce your utility costs.
