摘要:In order to identify index system property of battery management system, index system reconstruction and index weights reassignment are performed based on industrial and national standards, using multi-the analytic hierarchy process. The result shows that: compared to vehicle industry standard of seventeen technical indexes, new national standard have thirty-three indexes. And index system is rebuilt as two layers, where the first layer includes five indexes. By using of judge matrix, characteristic vector and consistent verify, all indexes weight and their consequences are confirmed. In the first layer, the index of performance of estimation, calculation and diagnose shows the maximum weight of 0.4283, and electrical adaptability has the minimum weight of 0.0710.
