Final answer:
High voltage systems in electric and hybrid vehicles include the air conditioning compressor, electric power steering, and electric water pump. The auxiliary battery operates at a lower voltage and is not considered a high voltage system.
Step-by-step explanation:
Besides the Hybrid Electric Vehicle (HEV) and Electric Vehicle (EV) motor systems themselves, there are other systems within these vehicles that may use high voltage. Systems that can employ high voltage include:
- A - Air conditioning compressor: The compressor can be powered by high voltage electricity, especially in electric and hybrid vehicles where it is not driven by a belt attached to the engine.
- B - Electric power steering: This system may use high voltage to reduce effort and provide a better steering response.
- D - Electric water pump: Some electric or hybrid vehicles use high voltage for the water pump to efficiently manage the cooling system.
The auxiliary battery (Option C), typically operates at a lower voltage and is used for running the vehicle's accessories and not the main high voltage systems.
