Abstract: Aiming at the issue of fuel economy of hybrid electric vehicle(HEV), a testing method for energy saving indexes of electrical components was studied and design schemes of test benches were proposed for testing motors, contoller and power batteries. After the analysis of relevant national and overseas testing standards, brief testing methods for component energy saving indexes were presented. Based on summaries of energy\|saving technologies of HEV, test items related closely with fuel economy of HEVs were indicated and the energy saving indexes of the driving motor and power batteries under different working conditions were discussed. A motor and a set of power batteries as components in HEV were tested by the proposed test benches. And the influence on fuel economy of the vehicle drew from the test results about these two components was analyzed. The research results indicate that the production test of electric components of HEVs can improve the fuel economy of HEVs.

Key words: hybrid electric vehicle(HEV); components; fuel economy; testing technology
