A system that captures kinetic energy and converts it back into electrical energy to recharge the battery. — Regenerative braking increases energy efficiency.

Q: What does 'SOC' stand for in the context of EV batteries?

State of Charge — SOC represents the remaining battery capacity.

Q: What is the primary function of the inverter in an EV?

To convert DC power from the battery to AC power for the motor. — The inverter drives the AC motor.

Q: Which of the following is a common type of battery chemistry used in EVs?

Lithium-ion (Li-ion) — Li-ion offers high energy density and performance.

Q: What is the purpose of the on-board charger (OBC) in an EV?

To convert AC power from the grid to DC power to charge the battery. — OBC facilitates charging at home or public charging stations.

Q: What is the difference between Level 1 and Level 2 charging?

Level 1 is slower than Level 2, using a lower voltage and amperage. — Level 2 offers faster charging speeds than Level 1.

Q: What is the function of the DC-DC converter in an EV?

To convert the high-voltage DC from the battery to a lower voltage DC for auxiliary systems. — The DC-DC converter powers vehicle accessories.

Q: What is 'kW' a unit of measurement for, in the context of EVs?

Power — kW represents electrical power.
