the electric vehicles cannot be universal because of their short batteries life and driving range. An ultracapacitor and a DC/DC converter were added to the pure electric vehicles constituting the compound energy storage system. Analyzing the operating state of vehicles
an improved logic threshold control method is proposed for controlling compound energy storage system. The whole vehicle model is established by using AVL CRUISE software
and the energy management strategy is simulated under urban condition.With the Brushless Direct Current Motor in 48V and 5kW and its controller HPC300 as the carrier
the compound energy storage system and its energy management system were built.The simulation and experimental results show that the compound energy storage system and its energy management strategy can avoid the input and output of high current of batteries
improve the life of batteries and the driving range of electric vehicles.
