Question

A ________is one in which only one energy converter can provide propulsion power.

Answer 1

A series HEV is one in which only one energy converter can provide propulsion power.

• In a series hybrid, only an electric motor provides all propulsion power to wheels.
• It helps to optimize fuel economy.
• A downsized IC engine drives a generator, which supplements batteries and can charge them when they fall below a certain charge level.
• It also helps to reduce emissions.
