Engineering Chemistry: Unit V: b. Energy Storage Devices Electric vehicles are the vehicles that are powered on electric power. These are also referred to as battery electric vehicles. ELECTRIC VEHICLES Definition Electric vehicles are the vehicles that are powered on electric power. These are also referred to as battery electric vehicles.
A battery-electric vehicle (BEV) is entirely powered by an electric motor; they solely rely on their battery packs. The electric motor converts the stored electrical energy into mechanical energy to propel the vehicle.
When the vehicle slows down, the electric motor functions as a generator, converting some of the kinetic energy into electrical energy, which is then stored in the battery. This process helps to increase the vehicle's range. Charging: Plugging an electric power source into an EV allows you to recharge the battery.
There are many technologies suitable for electric vehicle energy storage systems but the rechargeable battery remains at the forefront of such options. The current long-range battery-electric vehicle mostly utilizes lithium-ion batteries in its energy storage system until other efficient battery options prove their practicality to be used in EVs.
