| Abstract: | Specialized electric vehicle(EV) project of the national 863 project and Beijing Green Olympic project will improve EV development condition. According to the test of EV bus, the expressive form and generation principle of the battery pack imconsistency were studied; voltage inconsistency was mainly discussed. Regularities of distribution were generalized; commection of voltage inconsistency and service time was showed; theoretical nomal distribution and its basic parameters were determined; and conformity between theory and practice was verified. In the end, the measures were brought forward to prevent from enlarging the battery pack inconsistency. |
