Electric vehicle batteries are rechargeable energy storage systems that power electric vehicles (EVs). They are primarily made of lithium-ion cells, which store and release electrical energy to drive the vehicle's electric motor. These batteries are designed to provide a long driving range and can be charged at home or at public charging stations. The performance of electric vehicle batteries is influenced by factors such as capacity, charging speed, and lifespan. As technology advances, manufacturers are working to improve battery efficiency and reduce costs, making EVs more accessible to consumers. Innovations in battery technology also aim to enhance sustainability and reduce environmental impact.
