Gas: Optional (See also: Flexible Fuel PHEV's).
Plug-In Hybrid Electric Vehicles (PHEV's) are outfitted with a battery pack sufficient to power the vehicle from 20 to 60 miles on battery charge alone. Considering that half the cars on America’s roads are driven 25 miles a day or less, a plug-in with a 25-mile range battery could eliminate gasoline use in the daily commute of millions of Americans. The cost of an equivalent electric gallon of gas is estimated to be less than $1.00.
PHEV technology is already available and functioning. DaimlerChrysler is producing a Sprinter Van prototype with an all-electric range of 20 miles. Also on the road are existing standard hybrids that have been converted to plug-ins.
The Difference Between Standard Hybrids and Plug-in Hybrids: Basically, PHEV's use the same technology as the popular hybrids on the road today, but have a larger battery that can be recharged by plugging into a standard home outlet. Click here for a dissertation on this subject.
Key PHEV Attributes:
- Gets about twice the fuel economy of a conventional vehicle and 30-50% better fuel economy than a standard hybrid. - Plugs into a standard (120-volt) home electrical outlet to receive charge. - Depending on design and battery size can be driven 20 to 60 miles without the use of gasoline. - Useful in a Vehicle-to-Grid (V2G) configuration during peak electric usage daylight summer hours by using EV batteries as reservoirs for night time electric grid power.
Flexible Fuel PHEV's
PHEV technology can also be combined with existing flexible fuel technology to increase fuel efficiency even further as well as further reduce greenhouse gases and imported oil.
