Abstract: At present, the applications of motive batteries in EV are extensively used, because of complicate circumstance the consistency of Li-ion batteries are severely descented. If it is not used for quality evaluation and maintenance measure, cycle life is badly decreased. It is basis of Li-ion batteriy’s property and scientific service and maintenance analysis of motive Li-ion batteries system, using data acquisition of motive Li-ion battery. It is important effect to improve quality of motive Li-ion batteries in service and property analysis, at the same time it is influence for performance of EV. In this paper, the development and applied fields of quality evaluation of motive Li-ion battery is introduced.

Key words: Consistency, Quality evaluation, Data acquisition, Cycle life
