So I love the kick you get when you slam the accelerator but then you get a depressing huge orange mountain in your consumption chart. I understand this mainly comes from pulling hard on batteries and Peukert's law.
So why doesn't Tesla put in capacitor that could give max power for a few seconds; maybe 5s... after that you start breaking the law anyway. That would:
1- avoid losses due to pulling hard on batteries and Peukert's law = get the fun and the efficiency
2- make regen more efficient and available in freezing weather as recharging a capacitor is more efficient than recharging a battery
A few seconds of capacitors shouldn't take too much space or weight (300kW x 5s = 1500kWs = 0.42 kWh)
At 10Wh/kg you would need 40 kg of capacitors + some power electronics (10-20kg? I dont know). Seems manageable.
Capacitors either charge from battery or only on regen (customizable in user settings).
If the capacitor is empty then you just pull on the battery as normal and get the fun but without the efficiency.
I'm not sure what catastrophic failure of this 0.4 kWh capacitor would look like. I know capacitors discharge super fast and can vaporize cables but 0.4kWh could be small enough to limit the "catastrophicness" of failure.
And then you get the fun and the efficiency... you could even have cool beeping sounds telling you when you could get your next "free kick". so why didn't they do it?!
