【 摘 要 】

Impact of initial open-circuited potential on the Consistency of Lithium ion battery was studied, and the results showed that the greater the initial open-circuit potential difference, the greater the discharge voltage difference between the two cells, and the greater the voltage gap between two cells, the more serious the battery pack performance degradation will be caused, the greater the probability of safety accidents, the more serious safety problem.
