What is a Capacitor? A capacitor is a two-terminal passive electrical component that can store electrical energy in an electric field.This effect of a capacitor is known as capacitance. Whilst some capacitance may exists between any two electrical conductors in a circuit, capacitors are components designed to add capacitance to a circuit.
Development of supercapacitor hybrid electric vehicle
The functions of the energy storage system in the gasoline hybrid electric vehicle and the fuel cell vehicle are quite similar (Fig. 2). The energy storage system mainly acts as a power buffer, which is intended to provide short-term charging and discharging peak power. The typical charging and discharging time are 10 s.
