What is the difference between hev and phev?

Answer 1

PHEV is an abbreviation for Plug-in Hybrid Electric Vehicle. These vehicles, like other Hybrid Electric Vehicles (HEVs) have an onboard internal combustion engine that charges batteries or otherwise provides electricity to an electric motor. This electric motor either assists the internal combustion engine (in parallel HEVs) or is the sole mechanical link to the wheels (in series HEVs). What makes a PHEV different from a HEV is its ability to charge the batteries by plugging the vehicle in. This feature has the advantage of allowing the vehicle to run for some distance without running the internal combustion engine at all-thus reducing the use of petroleum.

The difference between a PHEV and HEV is that-a PHEV has all the abilities of a HEV but also can charge its batteries by plugging in to grid-provided electricity. The primary advantage of this-is the effective increase in fuel efficiency.
