- Thorondor 9mo agoYes, but a car can't use electricity at 1 MV and converting the megawatt back to something lower than 1 MV still produces a lot of heat.
- nine_k 9mo ago1 megavolt means huuuge spark gaps, I'd say no less than 20", given dry air. This also means very thick insulation, very bulky and expensive switches and breakers, etc. Tesla 3MW charger uses 1250V DC: https://en.wikipedia.org/wiki/Megawatt_Charging_System https://en.wikipedia.org/wiki/Megawatt_Charging_System Liquid-cooled charging cables are a thing. too; one of many: https://www.mouser.com/new/phoenix-contact/phoenix-contact-500a-liquid-cooled-charging-cables/ https://www.mouser.com/new/phoenix-contact/phoenix-contact-5...
- loeg 9mo agoVehicle battery packs are 400-800V today; not 1MV.
