Study on Dual-Energy Storage System Design for Pure Electric Vehicle

Abstract:

Under the energy structure dominated by coal in China at present, the development of electric vehicles is the best way to deal with the problems of energy, environment, climate change and sustainable development and the best choice to make the auto industry change from big country to powerful country. So far, driving mileage is still the bottleneck to restrict the pure electric vehicle commercialization. Making full use of the realization of finite energy source and improving the efficiency of the driving system and the regenerative braking are the urgent problems to be solved. Regarding to the dual-requirements for high-energy density and high-power density, the dual-energy storage system is designed to be a composition of battery and ultra-capacitor plus bi-direction DC/DC converter in parallel. The main-loop circuit of the dual-energy storage system is constructed, and the working states are analyzed.
