Electrical mobility is an emerging mode of transportation, causing rapid growth of battery pack usage in electric vehicles. These battery packs were having limited working life to be used in electric Vehicles. In addition, the disposal is becoming as a major threat to an environment. So there is a need to increase the working life of battery pack used in electric vehicles, to reduce the burden on environment. In this regard, this paper is focused on studying the life cycle estimation of battery pack. Battery pack degradation was observed through its self-discharge pattern and also due to the urge in increasing the rate of charging. Research study was focused on understanding the degradation rate due to self-discharge and also due to fast charging patterns in battery packs. This degradation rate was used as the key factor in estimating the working life of battery pack for electric vehicle application. In this work, open circuit voltage approach was used for developing the predictive model
