Engineering research of super-capacitor and dynamic lithium battery combined electric vehicle

Super-capacitor is newly-developed energy storage equipment with the characteristics of high power density ,long life ,wide temperature and rapid charge/discharge properties. At the same time, electric vehicle has some technology bottleneck including the short batter life, large power discharging at the accelerating time for power-type battery and low energy reproducing at the stop time ,these disadvantages affect greatly the application of the electric vehicle that battery life and battery accelerating multi-Cylinder discharging at that instant .The paper introduces that performances of super-capacitor and dynamic lithium battery, the research result of super-capacitor and battery combined electric power and its application for electric vehicle are also presented.
