Earlier quoted context omitted.
CCS has a 500 amp cap in the spec, so here is a limit to how fast 400V batteries can be charged on public infrastructure. Going to 800V removes that limitation as well. Tesla doesn’t care since they control everything and can ramp up the amps, but all other cars that want to charge more than 200 kW need to have higher voltage batteries.
True, but all these cars are quite far from having a flat 200kW charging curve anyway.
Higher voltage also reduces power losses.
Not sure what you are arguing against here, to be honest - are you defending Tesla‘s system? Slow charging is one of the main arguments against EVs, it’s great that this is finally being fixed.
