The technical name for these products is EVSE (Electric Vehicle Supply Equipment), commonly called a charging station or charging dock. These charging stations are built into the EV charging standard for electrical safety; first for the user, then the vehicle and then the power grid. The charging stations primary function is as electrical safety equipment. A standard home charging station, whether it is a Level 1 (120V) station or a Level 2 (240V) station, will provide pass through AC power to the vehicle for charging. The vehicle will convert this AC power to DC power and utilize that to recharge the batteries, the actual charger is on-board the vehicle. A charging station implements several layers of redundant safety features to protect the user from potential electrical hazards while connecting and disconnecting the station to the vehicle for charging. Once connected to the vehicle the station will inform the vehicle that power is available and at what level. From that point the vehicle takes over, initiates and takes full control of the power transfer, unless an electrical fault occurs, in which case the station will stop the power transfer immediately.
