Darn, we are still at 6.6kw charging... How could anyone even imagine that we will be able to charge our Leafs in 2 minutes in the near future????.....
Yeah and I want a Jet Pack to go to work..
Tesla charges at 110kW now. Porsche will be charging at 300 next year.
Just to be clear, Porsche has never said their vehicle will except 350 kW of power. They may have said it will be able to use a charging station that is capable of 350 kW, but then so is a Nissan LEAF or a Mitsubishi iMiev.
I’m going to be saying this a lot in the coming years, the placarded maximum charge rate of the station has very little to do with how fast it will charge your car.
A Tesla charge station can DC output 365a * 400v = 147kW, yet no Tesla car can charge over 120kW. Those same cars absolutley can charge at either 365a, or 400v, just not at both the same time.
The same is true of a Chevy Bolt EV, Nissan LEAF, BMW i3, or eGolf, or any number of other vehicles restricted to 125a. Virtually all public DC charge stations are physically capable of 500v, but no car Is.
So, while the charger is technically capable of 125a at 500v = 62.5 kW, all those cars listed above charge below 50 kW. Why? Because none of the cars are capable of more than 400v. In addition, none of them are capable of handling the rated 125 amps at their max battery voltage. Again, no car is charging at 125a * 400v = 50kW (well, there is one… the Tesla Roadster with a 416v battery).
It’s quite probable that should the CCS group ever publicly release their data, we will find that the maximum amperage is 400 and the maximum voltage will be 850 to 900:
