Research on Power Dividing Strategy for Hybrid Electric Vehicle

In order to eliminate negative effects of transient power demands, configurations and power source characters of series hybrid electric vehicles were analyzed. The power dividing strategy was established based on wavelet transform, and then it was tested in RT-LAB model to compare with the result of constant temperature control strategy. As it was shown in the simulation, the power dividing strategy had an advantage in power following. Meanwhile, power supply quality could be promoted and battery life could be extended.
