  1. What is the maximum continuous current permitted for AC Level 2 charging under SAE J1772?

    Answer: 80 A

    SAE J1772 allows AC Level 2 charging up to 80 A.

  2. Which component monitors individual cell voltages, temperatures, and state of charge in an EV traction battery?

    Answer: Battery management system (BMS)

    The BMS tracks cell conditions and protects the pack from overcharge, overdischarge, and overheating.

  3. During regenerative braking, what happens to the vehicle's kinetic energy?

    Answer: It is converted to electrical energy and stored in the battery

    The traction motor acts as a generator, converting kinetic energy into electricity that recharges the battery.

  4. An EV battery is rated at 75 kWh. What does this figure describe?

    Answer: Energy storage capacity

    Kilowatt-hours measure energy, so 75 kWh is the battery's storage capacity.

  5. During a DC fast-charging session, where does the AC-to-DC conversion take place?

    Answer: Inside the off-board DC charging equipment

    DC fast chargers contain their own rectifiers and deliver DC directly to the battery, bypassing the onboard charger.

  6. What is thermal runaway in a lithium-ion battery?

    Answer: A self-sustaining reaction where rising temperature releases more heat

    Thermal runaway is a chain reaction in which heat triggers reactions that produce more heat, which can lead to fire.

  7. Which vehicle type has both an internal combustion engine and a battery that can be recharged from an external outlet?

    Answer: Plug-in hybrid electric vehicle (PHEV)

    A PHEV combines a gasoline engine with a battery charged by plugging into EVSE.
