Seems like fast charging would be more of an issue for trucks, police cars, taxis, etc. that can’t be off the road charging for 4-8 hours because they’re not making money when they’re charging.
If someone is really concerned about recharging their luxury supercar in 4 minutes because they’re driving it cross-country or something, they are going to have a problem finding the special charging stations. If instead they’re just Matthew McConaughey wanting to take their Lincoln out on a spur-of-the-minute drive in a commercial, I doubt he needs to recharge it in 4 minutes (or that there’s a special recharging station on his route).

Maybe every object is a fuse in that case. Just talking out of my rear, cuz I don't really know.

I don't know what a short on a 100kwh equivalent capacitor would look like. Probably looks like a bomb. On 3/5/2019 10:11 AM, Mark Radabaugh wrote: Perhaps some type of supercap instead of a battery? That’s about the only way I could see truly fast charging time since you are not using a chemical reaction, just storing electrons. https://cleantechnica.com/2018/02/27/supercapacitor-research-promises-10-minute-charging-times-200-mile-range/ Safety should be interesting. That’s a hell of a lot of energy density with very little to rate limit converting it back to heat - talk about the potential for a really big boom.

Capable of up to 350KW, but would "typically" run in the 200KW range (give or take). To take advantage of the higher charge rates, the vehicle battery packs will need to be enhanced to allow them to take that amount of power. -- bp part15sbs{at}gmail{dot}com On Mon, Mar 4, 2019 at 4:01 PM Sterling Jacobson <sterl...@avative.net <mailto:sterl...@avative.net> > wrote: Again, I think they meant about 5 hours to charge, not just under four minutes, lol!

At 3.11 miles per kW that would be a 100 kWh battery. OK, within the realm of posibilities. 4:40 minutes to 80% battery capacity. So 280 seconds or .077 hours to dump 83 kWh into the battery. 83/.077=1067 kW So you have to have 1 Megawatt power source to charge? 2223 amps of 480 service.
