This work investigates the target-oriented design of an experimental, accelerated aging characterization of lithium-ion cells as an initial step in the design process of traction batteries for electric vehicles. In various test series, the relevance of static and dynamic loads in the operating modes parking, charging, and driving for cell aging is evaluated. Furthermore, potentials for accelerating the calendar and cyclic aging are evaluated regarding their effect on the aging mechanisms and modes involved as well as the achievable acceleration factors.
