A(n) ___ charger is commonly at a fixed location and supplies DC power directly to the batteries inside an EV.

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

Answer: (A)

Off-board charging refers to charging equipment that is external to the vehicle and typically installed at a fixed location. This setup can deliver DC power directly to the EV’s battery, bypassing the car’s onboard charger, which is why DC fast charging works quickly. Inside the vehicle, the onboard charger converts AC from a wall outlet or charging station into DC to store in the battery, so it doesn’t deliver DC directly to the battery from the outside. The terms pedestal-mounted or wall-mounted describe the physical mounting, not necessarily whether the power is DC or comes from outside the car. On-board indicates the charger is inside the vehicle, not located at a fixed external site.
