Abstract Over the last decade, a combined effect of various circumstances such as Climate Change, Rapid Urbanisation, Advancement in Battery Chemistry and concerns of Energy security have created a conducive environment for adoption of Electric Vehicles across the Globe. In India adoption of Electric Vehicles is aimed towards meeting tightening emission norms, addressing last mile connectivity in rural India and creating new employment opportunities. Government of India has several initiatives and incentives for promoting EVs across India. For Electric Vehicles Battery Cells are used with High Energy Density (200–220 Wh/kg). The end of life of Batteries is defined when there is a capacity fade by 20%-30%. Factors such as higher ambient temperature adversely impact the available life of Batteries in EV. This is important in particularly Indian Scenario where the ambient temperature in summer is considerably higher. After 20–30% capacity fade, the Batteries are not suitable to be used for mobility applications because of requirement of high power throughput. In this regard, it is important to explore additional applications for reuse of EV batteries by possibly giving them a second life in non-mobility related applications[1]. This paper has done a literature survey to obtain condition of Lithium Ion Batteries after their useful life in Electric Vehicles. A study has been presented to judge the suitability of these Lithium Ion Batteries in Grid Connected applications. Top |
