Impacts of Regenerative Braking on Li-Ion Battery

Electric vehicles are the future of the automobile industry. Strategies must be devised for achieving a greater degree of energy conservation and further reducing our reliance on fossil fuel driven technology. Regenerative braking is one of the methods for moving forward in the said direction. In this paper, we are going to see the various effects of regenerative braking on the battery life of a vehicle. We have focused on various parameters of degradation of battery life, especially lithium-ion batteries which occur during regenerative braking such as variation in charging C-rate, variation in temperature, etc. and their dependency on the cycle life of the battery. We have found that charging the battery beyond a particular C-rate which usually happens during regenerative braking leads to degradation of battery life.
