Battery Technology for Electric Vehicles
An electrical battery comprises of one or more electrochemical cells that convert stored chemical energy into electrical energy using electrochemical processes. The energy density of such batteries is mentioned in Joule/kg or Watt-Hour/kg or Watt-Hour/Litre. Energy density denotes how much energy a battery can mass and provide for the vehicle with a given size of the battery. So the higher the Watt-Hour/kg the better the battery becomes for traction since the weight of the battery does play a significant role, especially in electric vehicles as the batteries need to be carried along. Batteries with higher energy density need less volume and weight, making it possible to develop light weight electric ...
