Based on a systematic analysis of the dual power supply for electrical vehicle powertrain and on its control strategy, a simplified control algorithm which meets both continuous and heavy duty vehicular power needs was designed and integrated into the BDC control software. With this main component and super-capacitor module as a second assistant power source, and battery as the first primary one, a dual power supply system for short distance electric vehicle was designed and tested. Through rational design and selection of the energy sources and their parameters and optimal matching of powertrain energies in system level, the electric vehicle installing super-capacitors as an auxiliary power source can not only improve the electric vehicle performance, but also increase its vehicle range.
