    The fault current is going to be pretty high as well

    Not something to be used by the general public i would presume.

    Tesla SC is 480volt for 400v battery packs. Other manufacturers are looking at 800v battery packs!

    The V3 Super Charger is capped at 250kW
    Direct DC, bypassing the onboard AC/DC charger which only handles around 40 amps for home charging.

    Technical Details

    The Chargefox site at East Village Sydney features two 350kW capable Tritium chargers, plus an additional 50kW capable charger. At an average of 20kWh/100km the 350kW chargers can deliver up to 450km of range in 15 minutes, whilst the 50kW can deliver 60km in 15 minutes.
    Deceptive description - reading the above its likely 350kW/h. (Nameplate).

    Yes, it's very interesting. I assume it's per hour.

    350kW on a 480v SC is ~527 amps.

    That's why they are looking at 800v packs, for faster charging at lower amps.

    So with the chargeFox 350kW claim, you have to ask - at what voltage? The reality is, no EV on the market will let chargeFox put 350kW on a 400v pack. The charge rate is controlled by the car.


    The best you can get right now is the Tesla supercharger V3 which will give around 380amps to the long range Model 3 . The cable to car is a short run, and they are liquid cooled - apparently! Which allows for smaller gauge.

    Australia is still on V2 which is 120kW peak or ~180 amps. Minor
