Which term describes an EV charging method where power is delivered directly to the battery from a separate charger unit located away from the car?

• A. Wall-mounted charger
• B. Off-board charger
• C. On-board charger
• D. Pedestal-mounted charger

Answer: (B)

In EV charging, the decisive factor is where the power conversion happens and how the power reaches the battery. When the power is delivered directly to the battery from a separate charger unit located away from the car, you’re dealing with an off-board charger. The charging station handles the energy conversion and provides energy straight to the battery, which is typical in DC fast charging where the battery receives DC power directly and bypasses the vehicle’s own onboard charger. This differs from an on-board charger, which is inside the vehicle and converts incoming AC from a wall outlet or charging station into DC for the battery; here the car’s own unit handles the conversion rather than an external unit. A wall-mounted or pedestal-mounted charger describes where the charging hardware is installed, but doesn’t by itself specify that the power is delivered to the battery from a separate unit away from the car, which is the essence of an off-board charger.
