Where internal combustion engined cars get energy from burning petrol or diesel, an electric vehicle gets its power directly from a big pack of batteries. These are much like a scaled up version of the lithium-ion (Li-ion) battery in your mobile phone - EVs don't use a single battery like a phone, they use instead a pack which is comprised of thousands of individual Li-ion cells working together. When the car's charging up, electricity is used to make chemical changes inside its batteries. When it's on the road, these changes are reversed to produce electricity. EV batteries undergo cycles of 'discharge' that occur when driving and 'charge' when the car's plugged in.The battery on an electric car is a proven technology that will last for many years. In our Sri Balaji Battery Service, we provide best quality EV batteries and recharge facility of EV batteries. Lead-acid batteries power the majority of e-rickshaws.
