The key technology in Energy Management System of Electric Vehicle is researched in this paper. The hybrid power system constituted by the battery and the ultra-capacitor can combine the advantage of the high energy density of battery and the high power density of ultra-capacitor. Firstly, through the analysis of different structures, a suitable one is selected for this system. And then the importance of Energy Management System in the Electric Vehicle system is dissertated in this paper. Secondly, some theoretical study for the regenerative brake of electric vehicle has been expressed. Finally, the theory was verified by some result of system simulation and experiments.

Fuzzy Control Strategy

This thesis puts forward one optimal adaptive fuzzy control method based on the pure electric vehicle energy management system of the fuzzy control which has been founded already. By adding an optimizing researching model based on the conventional fuzzy control strategy, the thesis can pick up the valuable control rules based on the dynamic programming theory and also can adjust the parameter of the fuzzy controller automatically according to the system operating. These can make the sum of the energy loss reduce to the min. The experiment points out that this method makes the vehicle possess good economic performance in the same driving cycle.
