Not all electric car batteries are the same. EV battery packs come in different sizes and their capacity is measured in kilowatt hours (kWh). Generally, the larger the capacity in kWh, the longer the range of the EV.
The chemical composition of batteries will also vary between cars and manufacturers.
Among the different battery types, Lithium-ion batteries are the most popular with a longer lifespan than most other batteries. They’re also generally cheaper to produce, generate less heat during charging and can be charged to 100% with little battery damage.
