Which battery in an electric car is considered high-voltage?

• A. 12-volt auxiliary battery
• B. Starter battery
• C. Traction battery
• D. Nickel-metal hydride battery

Answer: (C)

In an electric car, there are two battery systems: a high-voltage traction battery and a low-voltage 12-volt system. The traction battery is the main energy source for propulsion, delivering hundreds of volts to the electric motors to drive the car. That makes it the high-voltage battery. The 12-volt auxiliary battery powers lights, controls, and other accessories, and is much lower in voltage, so it isn’t considered high voltage. Nickel-metal hydride is a chemistry type that has been used in some vehicles, but the term “high-voltage battery” in this context refers to the traction pack powering the drivetrain.
