Accelerated aging test AAT is required to efficiently evaluate the operating life of lithium ion batteries LiB It can partially substitute traditional aging test which typically lasts for thousands of LiB charge discharge cycles A practical AAT should consider the operation condition features OCF in its aging models such as charge discharge rate ambient temperature ampere hour throughput and the time distribution of current rate TDOCR This paper proposes a new AAT method for optimizing both reduction in test time and TDOCR reconstruction An algorithm is designed to ensure the OCF equivalence of the AAT profile and the operating profile The limitations of aging stress threshold and the retention of TDOCR are mainly considered and addressed by the segmented equal scaling method SESM of feature reconstruction Based on the aging model featured by the Arrhenius formula the validity of the method is verified with typical FUDS profile and NEDC profile
