Development of supercapacitor hybrid electric vehicle
In 2000, the Honda FCX fuel cell vehicle used electric double layer capacitors as the traction batteries to replace the original nickel-metal hydride batteries on its previous models (Fig. 6). The supercapacitor achieved an energy density of 3.9 Wh/kg (2.7–1.35 V discharge) and an output power density of 1500 W/kg.
