An Electric Vehicle Battery is a rechargeable energy storage device used to power the electric motors and auxiliary systems in electric vehicles. EV batteries are lithium-ion batteries known for their high energy density and rechargeability.
Increasing the volumetric energy density of batteries allows electric vehicles (EVs) to travel further without increasing the size of the battery pack. Conversely, it can allow an EV to travel the same distance with a smaller battery pack, thus saving space, weight, and manufacturing costs.
They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density. Compared to liquid fuels, most current battery technologies have much lower specific energy. This increases the weight of vehicles or reduces their range.
The energy density of an electric vehicle (EV) battery significantly influences its performance. Higher energy density means more energy stored per unit weight of the battery, leading to increased driving range or reduced weight for the same range.
The weight of an EV battery significantly contributes to the overall vehicle weight. Typically, passenger EVs range from 600kg to 2600kg in gross weight, with battery weights varying from 100kg to 550kg. A more powerful battery correlates with a greater weight, as it contains more energy.
In 2008, lithium-ion batteries had a volumetric energy density of 55 watt-hours per liter; by 2020, that had increased to 450 watt-hours per liter.
