Batteries

Batteries[edit]

lithium ion polymer battery prototypes. Newer Li-poly cells provide up to 130 Wh/kg and last through thousands of charging cycles.

An electric-vehicle battery (EVB) in addition to the traction battery speciality systems used for industrial (or recreational) vehicles, are batteries used to power the propulsion system of a battery electric vehicle (BEVs). These batteries are usually a secondary (rechargeable) battery, and are typically lithium-ion batteries. Traction batteries, specifically designed with a high ampere-hour capacity, are used in forklifts, electric golf carts, riding floor scrubbers, electric motorcycles, electric cars, trucks, vans, and other electric vehicles.[75][76]

Efficiency[edit]

EVs convert over 59–62% of grid energy to the wheels. Conventional gasoline vehicles convert around 17–21%.[77]

Charging[edit]

Grid capacity[edit]

If almost all road vehicles were electric it would increase global demand for electricity by up to 25% by 2050 compared to 2020.[78] However, overall energy consumption and emissions would diminish because of the higher efficiency of EVs over the entire cycle, and the reduction in energy needed to refine fossil fuels.
