I think charging cables would melt from such currents. Or you would need a superconductor charging cables for your supercapacitors. Super everything :)

- geon 10y agoThicker cables? Or would they be too heavy?
- emeraldd 10y agoThere will be a physical limit when you attach the cables to the capacitor. At some point, the cable will be larger than the capacitor itself. Also, there are internal components (i.e. the leads attaching to the 'plates') that will become limiting factors. All that to say, there's a physical limit to how much bigger you can make the cables and actually still attach them to the capacitor.
- geon 10y agoAt some point, the thermal capacity of the cables will approach that of the brake discs of a normal car. They rarely get hot enough to melt, even though they pretty much absorb the entire braking power. I'd calculate the resistance of copper cables vs car mass and delta v, but I'm too lazy.
- fzzzy 10y agoCould use higher voltages instead.
- achr2 10y agoNot for supercaps, most have a breakdown voltage below 5 V.
