Abstract

For optimizing the maintenance strategy of electric vehicle (EV) changers, it's necessary to have a comprehensive evaluation for it by using its monitoring data. From the battery, electrical machinery transmission and charge-discharge process, 26 characteristic quantities are chosen as EV changers operation state indicators, the common factor indicators are extracted by using the factor analysis method and then the EV changers state indicators are classified by the independent common factors; the classified indicators are screened by using stepwise regression analysis, and the indicators that contribute little to the evaluation result are excluded, thereby the EV changers operation state comprehensive evaluation system are established. Combined hierarchical structure of EV changers evaluation and radar map method, the layered radar map method is proposed for EV changers comprehensive evaluation.
