| Faced to the problem of the energy sources shortness and environment pollution, hybrid electric vehicle, an intergraded-vehicle between custom engine vehicle and electric vehicle, has become hot point of the global automobile industries research and development because of its theoretic feasible and unique technical advantages. However, evaluating and improving HEV performances, especially dynamic and economical performance, not only needs theoretic simulation but also needs vast test datum analyzing. And vehicle battery, as one of the two HEV energy sources, is always the feeble section of the HEV, because performance difference of the each battery module in series directly affects the whole performance of the battery group and HEV.Firstly, the paper discusses test theory of the Hybrid electronic vehicle (HEV), making an outline of the HEV test, and stresses on the comparing and analyzing of the dynamic and economical performance between several kind of EQ6110HEV and custom engine vehicle by the test datum, validating advantage of this HEV control policies, drawing out oil measurement ways on the feature of conmuns high-pressure engine, drawing out way to improve road test rules based on diposaling result of city-bus city-drving data. Then, the paper analyzes vehicle battery charge-discharge stage during the HEV performance test, validating battery group performance and put up the necessity of design battery management. And the paper analyzes battery's performance and capability form the battery electrochemistry reaction theories, building battery remnant energy measuring model, modifying the define of the battery SOC, analyzing each parameter which influencing battery performances, drawing out calculating method of battery SOC and its malfunction diagnosing and policies of the battery thermal management. At last, the paper gives structure of the battery management's hardware and software, providing theoretic base for its further research and design.
