Energy storage systems like batteries are essential for electric vehicles and plug-in hybrid electric vehicles. Electric vehicle batteries can be either primary batteries or secondary rechargeable batteries, which are used to power battery electric vehicles. Electric vehicle batteries differ from starter batteries as they are designed to provide sustained power over long periods of time and must be safe, high-power, high-capacity, small and light, low-cost, and have a long life. Common electric vehicle battery types include lithium-ion, lead-acid, nickel-cadmium, and nickel-metal hydride batteries.

2. 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.

4. 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.
