摘要：In order to solve the problems that lithium-ion power battery cannot reflect state of health(SOH) in sorting process , the parameters which can reflect the battery SOH, such as capacity, AC resistance and self-discharge current, were used as the input vector of battery sorting model, fuzzy c-means clustering analysis and support vector machine based on cross validation algorithm to the battery for classification and recognition were used, and lithium power battery sorting model was established and the same batch of power battery were separating tested and according to the experimental results, batteries was divided into groups. The test results showed that: battery electrochemistry was having a good consistency. The variation of capacitance was less than 5% while there was 1500 cycle life.
