What is a PHEV and how is it different from a standard hybrid vehicle?
Both standard hybrids and Plug-in Hybrid Electric Vehicles (PHEVs) are powered by a combination of electricity and liquid fuels; however, PHEVs draw their charge from the engine and captured brake energy, as well as from the electrical grid when they are plugged into an electrical outlet. PHEVs also have a set of batteries that provide electricity to an electric motor, allowing the battery pack to be even further recharged by plugging-in.

PHEVs have traditional fuel tanks and internal combustion engines, so they do not face the range limitation of electric-only cars. As a result, the vehicles can travel up to 30 miles on electricity before using the standard, gas-electric operating system and get up to 100 miles or more per gallon.
