Everything about Battery Electric Vehicle totally explained
The
battery electric vehicle, or
BEV, is a
vehicle that utilizes chemical
energy stored in
rechargeable battery packs, and
electric motors and
motor controllers instead of
internal combustion engines (ICEs). Some confusion arises because the industry often refers to BEVs when it means
electric cars.
Vehicles using both electric motors and
ICEs (
hybrid electric vehicles) are examples of
hybrid vehicles, and are not considered pure BEVs because they operate in a
charge-sustaining mode. Hybrid vehicles with batteries that can be charged externally to displace some or all of their ICE power and
gasoline fuel are called
plug-in hybrid electric vehicles (PHEV), and are pure BEVs during their
charge-depleting mode. BEVs include
automobiles,
light trucks, and
neighborhood electric vehicles.
Vehicles
The concept of battery electric vehicles is to charge batteries on board vehicles for propulsion using the electric grid. The main advantages of battery electric vehicles is that (1) no pollutants are emitted directly by the vehicle potentially reducing urban pollution and (2) gasoline is replaced by electricity, reducing dependency on foreign fossil fuels. The electricity stored within the battery can be generated by any source, including renewable, nuclear, natural gas, coal and petroleum. Battery electric cars are becoming more and more attractive with the advancement of new battery technology (Lithium Ion) that have higher power density (for example more range with less batteries). Battery electric vehicles provide a great alternative to reduce urban pollution, and decrease dependency on foreign fossil fuels.
Electric bus
Milk float
A common example of the battery electric vehicle is the
milk float. Since it makes many stops in delivering milk it's more practical to use an electric vehicle than an ICE, which would be idling much of the time.
Garbage Truck
With a similar driving pattern of a delivery vehicle like the Milk Float above, Garbage trucks are excellent candidates for electric drive. Most of their time is spent stopping, starting or idling. These activities are where
internal combustion engines are their least efficient. In preparation for the 2008 Olympic Games, 3,000 of the internal combustion engine garbage trucks in
Beijing were replaced with
lithium ion polymer battery pack electric drive trucks.
Pickup trucks
In early 2009, Phoenix Motorcars [*http://www.phoenixmotorcars.com/index.php] will be making both their SUT and SUV available for public purchase. One of the surviving electric vehicles from the late 1990s is the
Chevy S-10 electric pickup truck. Many other vehicles from this era, such as the
General Motors EV1 were recalled and destroyed. A newcomer is the
Miles Electric Vehicles ZX40ST electric truck now available in the United States.
Miles Electric Vehicles is based in
Santa Monica, California.
