Hybrid vehicles also use the motor as a generator to charge the battery.

• A. True
• B. False
• C. They use a separate alternator
• D. They generate heat for cabin warming

Answer: (D)

In a hybrid, the drive motor can operate as a generator. When the vehicle brakes or slows, the motor acts in reverse to convert some of the kinetic energy back into electrical energy, which is stored in the high‑voltage battery through the inverter. This regenerative charging is how the battery is replenished, creating a loop where energy used for propulsion can be recovered and reused. The cabin-heating idea isn’t how the battery gets charged—heating uses engine waste heat or electric heating, not charging the battery. So the statement about charging the battery with the motor acting as a generator is true.
