The battery life is one of the central challenges in the development of electric vehicles. This thesis investigates the aging of lithium-ion batteries in electric vehicle applications based on extensive experimental aging studies, which reproduced up to 200,000 km of driving. Several methods for nondestructive aging diagnostics were applied to identify the dominant aging mechanisms for calendar and cycle aging. Based on the results of the aging studies, optimized operational strategies were derived which prolong the battery life.
