“A 9-minute charge time to reach 80% capacity on a 600 mile range battery?”
The amps to do that must be huge - tens of thousands. Wish they gave enough data so we could figure it out.
120kWh to take a model S sized vehicle from 0 to 80% if it had 600 miles of range.
Tesla S use 250 watt hours per mile so 600 miles is a 150kWh sized pack. 80% of that is 120kWh.
V4 supercharger standard maxed out in testing for it’s international certs at 1000 volts and 1000amps through the stock NACS plug my buddy Shaun is an engineer with Tesla Austin. They got their cert so they passed the safety tests. 1000V and 100amps is 1000kw
120kWh in 9 min is 6.66C so you need 792kw over 9min. Using the 800V standard pack voltage that all the majors are using now KIA Hyundai,Benz, BMW, VW...You then need 990 amps just under the limit of the latest V4 standards. There is your answer. Tesla also has the megacharger standard grow Cybertruck and TeslaSemi that’s 1000v and 3000amps but it’s liquid cooled megastandard plugs not passive cooled NACS plugs. 1 megawatt for NACS and 3 megawatts for megachargers. Megapacks hold 3.9 megawatts each so they would support 4 V4 superchargers or one megacharger at less than 1C rates on the packs which is not stressing them at all. They could do 4C and still have 2000 cycle lives if using LFP cells. With a 6 month payoff and 365 cycles per year you could do 4C and burn them out in 5 years with a 10 times ROI still $$$$ laugh all the way to the bank. Chargers are money making machines.
