Of those considering an electric car purchase, 50% view the average battery life at 100,000 miles or more, and 46% believe average battery life lasts 65,000 miles or less. Cycle life is based on the depth of discharge (DoD). Shallow DoD prolongs cycle life. Cycle life is based on battery receiving regular maintenance to prevent memory. Ultra-fast charge batteries are made for a special pupose. (See BU-401a: Fast and Ultra-fast Chargers) Self-discharge is highest immediately after charge. NiCd loses 10% in the

Generally, the capacity of a lithium-ion battery is stable for a while. Then it takes a sharp turn downward. The plummet point varies widely, as most 21st-century consumers know.

Electric vehicles (EVs) in severe cold regions face the real demand for fast charging under low temperatures, but low-temperature environments with high C-rate fast charging can lead to severe lithium plating of the anode material, resulting in rapid degradation of the lithium-ion battery (LIB). In this paper, by constructing an electrode–thermal model coupling solid electrolyte interphase result in end-of-life have already been found, depending on how the cell is used. Such information would enable a product designer to either extend life or predict life based upon the usage pattern. However, parameterization of the degradation models remains as a major challenge, and requires the attention of the international battery community. 1 . 395 108 142 401 399 229 287 242
