Top Ten Things to Know about Plug-in Hybrids

1) Plug-in Hybrid Electric Vehicles (PHEVs) are hybrids with high capacity batteries that can be charged by plugging them into an electrical outlet or charging station. PHEVs can store enough electricity from the power grid to significantly reduce their petroleum consumption under typical driving conditions.

2) There are two basic PHEV configurations:

Series PHEVs, also called Extended Range Electric Vehicles (EREVs). Only the electric motor turns the wheels; the gasoline engine is only used to generate electricity. Series PHEVs can run solely on electricity until the battery needs to be recharged. The gasoline engine will then generate the electricity needed to power the electric motor. For shorter trips, these vehicles might use no gasoline at all.
Parallel or Blended PHEVs. Both the engine and electric motor are mechanically connected to the wheels, and both propel the vehicle under most driving conditions. Electric-only operation usually occurs only at low speeds.

3) PHEVs also have different battery capacities, allowing some to travel farther on electricity than others. PHEV fuel economy, like that of electric vehicles and regular hybrids, can be sensitive to driving style, driving conditions, and accessory use.

4) PHEVs eliminate the problem of range anxiety associated will all-electric vehicles, because the combustion engine works as a backup when the batteries are depleted, giving PHEVs driving range comparable to other vehicles with gasoline tanks.

5) The environmental benefits of plug-in hybrids and electric vehicles increase if they are powered by electricity from ‘green’ sources such as solar, wind or small-scale hydroelectricity
