Chevy Volt: Plug In Hybrid Electric Vehicles

The World's First Plug-In Hybrid!

 

Coined as a plug-in series hybrid vehicle it is being introduced under the General Motors Chevrolet Brand.

 

The Volt's propulsion system will be based on GM's new E-Flex platform which was derived from the General Motors advanced technology vehicles; GM AUTOnomy, the GM Hy-Wire and the Chevrolet Sequel.  With the Volt being the first step in reinventing the automobile.  


As GM is the first to create this technology other car manufacturers like Mercedes, Nissan, BMW, Honda, and Ford are becoming fast followers of this technology.  With more cars like this getting 100 miles per gallon and more (GM Estimates 240 MPG) the world of transportation will be changing fast.

 

GM has also expanded this revolutionary platform with the Cadillac Converj concept, the Opel Ampera Concept and the Vauxhaul Ampera Concept.

 

At an expected purchase price of $40,000 and an estimated 200 m.p.g. GM expects to sell all 10,000 of the first year's production run in the first year.

 

 


Unlike current commercially available hybrids, the actual propulsion of the Volt is accomplished by the electric motor, as the internal combustion engine (ICE) is not mechanically connected to the wheels. With fully charged batteries, this electric power may be sourced exclusively from its onboard lithium-ion batteries, for up to 40 miles (64 km), a distance capable of satisfying the daily commute of 75% of Americans, which averages around 33 miles (53 km).

After 40 miles (64 km), the range of the Volt will need to be extended through the use of a small 4-cylinder ICE which drives a 53 kW generator. The electrical power from the generator is then sent to either the electric motor or the batteries, depending on the state of charge (SOC) of the battery pack and the power demanded at the wheels. The distribution is controlled by the electronic control unit (ECU) of the vehicle. This effectively extends the Volt's potential range to as much as 640 miles (1,030 km) on a single tank of fuel(which could be potentially extended for longer trips through conventional refueling).
