Abstract:A new type storage energy element, hybrid super-capacitor, is introduced, which can be used for pulse source system. The hybrid super-capacitor is composed of anodes of electrolytic capacitor and cathodes of electrochemical capacitor, so it has the characteristics of high working voltage and low inner resistance. When the hybrid super-capacitors are connected in proper series and parallel to form storage energy device, the device has the perfect performances of high energy density and fast charging and discharging, and can meet the needs of pulse power technology. A power source was designed for electric vehicle, which is based on the hybrid super-capacitors and batteries in parallel connection. The simulation and experiment results show that it can export high peak power and peak current, achieve the optimal matching of output energy, attain the best ratio of performance and price.
