Which statement best describes charging requirements for BEVs and HEVs?

Which statement best describes charging requirements for BEVs and HEVs?

• A. BEVs require external charging to operate; HEVs do not require external charging and rely mainly on the gasoline engine and braking for energy.
• B. BEVs and HEVs both require external charging to operate.
• C. HEVs require external charging, while BEVs generate energy from braking.
• D. BEVs operate without any charging through the gasoline engine.

Answer: (A)

Charging needs differ between BEVs and HEVs. BEVs rely entirely on electricity stored in their battery packs and must be charged from an external power source to operate. They do not use a gasoline engine to drive the wheels. HEVs combine a gasoline engine with an electric motor, and their battery is charged during operation by the engine and by regenerative braking, so they can run without plugging in. Because BEVs require external charging while HEVs can operate without it and rely on the engine and braking for energy, the described statement is the best description of their charging behavior. (Note: plug-in hybrids exist, which do require external charging, but that’s a different category.)
