2. Introduction Energy storage systems, usually batteries, are essential for all electrical vehicles, plug in hybrid electric vehicles. An electric vehicle battery (EVB) or traction battery can be either a primary ( eg.material , air) battery or a secondary battery ( rechargable battrey is used for propulsion of Battery electric vehicles BEVs) Electric vehicle batteries differ from starting and ignition (SLI) batteries because they are designed to give power over sustained periods of time EV batteries requirements safe,high power,high capasity , small and light, large formal, long life low over all cost.

3. Types of ev batteries Lithium ion battery Lead-acid battery Nickel-Cadmium battery Nickel-metal hydride battery

4. Lithium-ion battery INTRODUCTION A lithium ion battery is a family of recharegable battery type in which lithium ion move from the – ve electrode to the + ve electrode during discharge and back when charging.
