I also have doubts about that one. Too high a CV (power) product in the case of a catastrophic event during charge or discharge raises the prospect of serious arcflash injuries where the vaporized component itself (supercapacitor, charging station, anything close to them) is converted to a conductive plasma that can cause extensive second and third degree burns, fires and even electrical explosions in case of a catastrophic failure. The maximum current to private residences is limited for just this reason. I’m not sure how a much higher charge rates would be permitted for an electric vehicle even if technically feasible.
