31、arily connected to the land vehicles battery. Ifthe cable is connected through a switch and therefore does not have a continuous path to the exteriorof the power packs enclosure, then the definition shall apply to the portion of cable that exits the powerpacks enclosure.5.5 BOOSTER FUNCTION When the

(A subset ofelectrochemical capacitors referred to as an “asymmetric electrochemical capaci

The unique highly-porouselectrode increases its surface area for holding charge resulting in much larger capacitance and energydensity than other types of capacitors. Electrochemical capacitors differ fr
40、om common electrolyticcapacitors in that they store charge at the liquid-solid interface of the electrodes when a potential isapplied rather than in a solid dielectric material covering the surfaces of the electrodes.
