aka a lightning bolt
Not really as large capacity capacitors (this one seems to be 4V) tend to be low voltage as well. You can touch the terminals without harm but attempting to short them is going to be, er, entertaining. I have accidentally touched a 200V capacitor and it was not fun.

That's interesting. What good is 4V in an EV? You'd need cables as thick as your arm to handle the amperage to do anything useful.
Otherwise, you can use a step-up voltage converter to generate a voltage as high as you want, in order to distribute power at greater distances. You can make bidirectional converters, which work as step-down converters for charging and as step-up converters for discharging.

I think of Styropyro's something like 400 car batteries wired together.

My EV has the opposite problem, something like half throw is full throttle and then the rest of the pedal does nothing. They do it for marketing reasons but I still don't like it
That’s annoying. The Genesis throttle maps are what you’d expect: Eco counteracts a leadfoot, Comfort has good pickup, Sport is borderline irresponsible in neighborhoods, Boost is unreasonably fun.
And no mention of the self discharge rate.
For a similar part in this class: Low Leakage Current as small as 1µA Low Self-discharge rate, 72 hours @ discharge https://abracon.com/datasheets/AHCR-S04R0S.pdf The more the Farads the higher the leakage. The higher the tempature the higher the leakage.
Dumb question but I though capacitors store energy and not power?
Power is just the time derivative of energy, like velocity is the time derivative of position. Both batteries and capacitors store energy, which they can release at some given peak and average power. Batteries tend to focus more on energy density (energy stored per weight), while capacitors tend to focus more on power density (rate of energy stored or released per weight).

You could have just said yes.
Another cool insight is around "dual" relationships in circuits. You can often think of some components as roughly analogous to each other, with a switch of current and voltage. For example, if you connect a capacitor in parallel with a power supply and load, the voltage across it will increase as a function of time until it reaches the power supply voltage. Similarly, if you connect an inductor in series with a power supply and load, the current through it will increase as a function of time until it reaches the current that would otherwise pass through the load.
Like most good analogies, it's not 100% airtight, but it provides useful insights.
