Performance of battery cells in an electric vehicle (EV) highly depends on environmental temperature. However, many studies do not consider its regional or seasonal characteristics. These characteristics can have a significant impact on the EV battery life in California, where there is a large variation of climate across the state. In some regions, the maximum ambient temperature can cause a rapid life degradation of the battery cells. In this study, we investigated the environmental temperature effects of six major cities in California on the capacity fade of the EV battery cells. A numerical model of an automotive battery pack and cycle-life model of a lithium-ion battery cell were implemented to predict the cell temperature and its corresponding capacity loss. The numerical results demonstrated the regional and seasonal effects of environmental temperature must be considered to prevent rapid life degradation in the automotive battery cells.
