Which component is not responsible for creating or transmitting high-voltage currents?

• A. Traction battery
• B. Inverter
• C. High-voltage cables
• D. Heated seats

Answer: (D)

High-voltage systems in electric vehicles rely on three main parts: the traction battery as the energy source, the inverter that converts that energy into the form used by the electric motor, and the high-voltage cables that physically carry the current between components. These are all involved in creating or transmitting high-voltage power. Heated seats, by contrast, are a low-voltage load. They typically run off the vehicle’s 12-volt system, or receive power through a DC-DC converter from the high-voltage battery, but they do not generate or carry high-voltage currents themselves. That makes heated seats the component that does not create or transmit high-voltage currents.
