If a thermal management system were added to maintain battery cell temperatures within a 20-30oC operating range year-round, the battery life is extended from 4.9 years to 7.0 years cycling the battery at 74% DOD. Life is improved to 10 years using the same thermal management and further restricting DOD to 54%.
