Hybrid energy storage devices and processing method thereof

The present invention is a hybrid vehicle (HEV: Hybrid Electric Vehicle) relates to, or structure and operation method of the hybrid energy storage device of the electric vehicle (EV) hybrid energy storage devices that are used in, the present invention is connected to the generator and ultra-capacitor for storing the generated electric energy; And a battery for storing electric energy along with the ultra-capacitor; Energy management system for generating a switching control signal detecting the remaining capacity of the ultracapacitor and the battery and, according to the detected remaining capacity and whether or not the regenerative braking; And a one-way power converter to charge the battery when the discharging energy of the ultra-capacitor dynamic braking in response to the switching control signal generated from the energy management system; If the remaining capacity of the battery or regenerative braking in response to the switching control signal generated from the energy management system is not less than a certain value it is to implement the hybrid energy storage device to switch separating the battery and power supply line. Hybrid energy storage device, an ultracapacitor, the battery, a one-way power converter
