As I wrote in a similar thread...
““can be fully charged in five minutes”
Let’s see....
Assuming a battery of 100KWH (Tesla size). With 240 volts, you would need 100,000/240 = 417 amps for an hour. To do it in 5 minutes you would need 12 times that, or 5000 amps!!
If you use a voltage 4 times that which is what the superchargers use, you still would need to pump through 1250 amps. (Most houses are wired for 100-150 amps)
You would need a cable the size of a fire hose, and I doubt the battery could handle being flooded with all those electrons in such a short time.
Or did I screw up somewhere?”
Tesla superchargers, now, use 500 or 1000 volts. They say up to 1.2 MW in the V4 cabinet. Here is an article about them:
“According to Max de Zegher, Tesla’s Director of Charging, eight stalls require less than 1 MW 99% of the time: “Posts can peak up to 500kW for cars, but we need less than 1MW across 8 posts to deliver maximum power to cars 99% of the time.” This indicates that with a proper dynamic allocation of power, there should be no issues. Remember that the peak power values are often used only for a brief period.”
At a rate of 1.2 MW, the V4 cabinet would need about 8.33 minutes to deliver 100 kWhr. They can deliver the 1.2 MW for the Tesla Semi-truck.
It sounds fairly close to what Donut Labs is claiming. Their new motorcycle battery would only have about a 50 kWhr battery.
