80kWh battery 10 minutes 80*(60/10)=480kW Not gonna happen.

  Tesla’s V3 super chargers charge at 250kW, IIRC VW/Audi are working on a 500kW charging for their (s)HV cars. The Kia EV6 which is pretty much on the market already supports 350kW charging with 800v DC chargers… they demonstrated 70% charge in only 18min with a production car and a production charger. So I don’t see why 480kw would be unrealistic especially with a new cathode technology. Whether this one works or not I don’t know but the 480kW isn’t some limit that can’t be broken because we are already reaching it with existing batteries.

    Even Tesla has hinted towards a 1 MW charger for their electric Semi. https://insideevs.com/news/509506/tesla-semi-megacharger-frito-lay/ https://insideevs.com/news/509506/tesla-semi-megacharger-fri... Likely to be installed soon, so 480W definitely isn’t out of the question.

      the installation sooner or later depends on the installer and the conditions to be able to install a qualified power supply:https://www.couponxoo.com/electric-coupon-code https://www.couponxoo.com/electric-coupon-code

      yes 480w should be widely used in all configurations on computer equipment :yes 480w should be widely used in all configurations on computer equipment bị

    Makes you appreciate how much potential energy there is in a tank full of gasoline. A long row of rapid charging electric cars can give a smelting plant run for its money

All those promises are the reason why I struggle to buy an EV today. I would totally be able to manage the tradeoffs (charging time, autonomy…) since I’d have another vehicle. But I have the feeling that years to come (5-10) are going to be game changing and that the car I would buy today could lose its resale value rapidly.

  > the car I would buy today could lose its resale value rapidly So like any other car after 5 years? People somehow got used to Tesla’s maintaining their value mainly because they didn’t really changed the design much so it’s hard to tell which year it is and that they were and somewhat still are supply limited.

    > So like any other car after 5 years? Maybe it's a judgment error from me but I'd say more. There is this popular belief (which tends to be proven wrong with time) that batteries lose a lot of capacity with time. As for Tesla, it's a edge case since Tesla as a "luxury" branding. I'm thinking about other manufacturers since I don't want to put this much on a "second" car. In France we have a pretty successful EV car named Renault Zoé, I think I'll to start with this one, it have Ok specs and can be found used under 10k€.

      I'm curious is that final price, with taxes and battery? New ones in Poland start (!) at almost 3x that, and used ones under 10k€ are only damaged and/or without battery. At your price it may make sense as a "car to commute".
