Implementation of Frequency-Approach-Based Energy Management for EVs Using Typhoon HIL402

Using Hybrid Energy Storage System (HESSbattery and super capacitor) to extend the lifespan of batteries and travelled distances has been selected by many research laboratories in the world. This is particularly due to the fact that batteries have high energy density, but its lifespan is reduced when operating with electric currents with high harmonics. In this paper, we use Fast Fourier transform Analyzer of the traction current as the basis to distribute the suitable current of battery and super capacitor. The algorithm has been simulated in Matlab then implemented in DSP card to control a electric vehicle (EV) that is emulated in signal Hardware in the loop (S-HIL) HIL402 of Typhoon. Results show that HESS can increase the battery lifetime as well as extend the running distance per charge compared to the case of using only battery. The S-HIL system should be a good and effective tool for further researches on energy management of EVs.
