I'll bite. They dumped a lot of power in a small amount of time. Sounds like the perfect job for a mega capacitor to streamline deployments. Other than the successful technology, Mrs. Lincoln, what are your gripes?
Cool now at your busy "gas" station keep it working as the pile gets exhausted and you don't have the supporting grid to be able to deliver the needed power to keep it stocked with "gas".
At least not in Europe.
From what I read it's 1500 kW at 1000V or Peak use of 1.5 MW at 1000 A. That's a crazy amount of power.
You will exhaust your piles quickly, or they are enormous. So it's like "quick-charge" until we run out?
They simply use a few grid storage batteries. Chargers don't charge at 1.5MW 100% of time. You also have people driving in and out of the station. The math works out really well.
