Yup, not an issue. When you're charging at 120kW the whole car hums and cooling system is going full-tilt. Pretty incredible to see 400VDC @ 300A go straight in

- VLM 10y agoIf you run the math its only roughly 170 continuous horsepower running thru those power cables, assuming 100% efficiency etc. If they added another order of magnitude or two to that charge rate, then it would be impressive.
- sammydavis 10y agoYou have to take into account that the electric motor in a tesla is more efficient than a gas motor (3-4x). The reasoning is that a gallon of has has about 33.6kwh in a gallon (see wikipedia (https://en.wikipedia.org/wiki/Miles_per_gallon_gasoline_equivalent https://en.wikipedia.org/wiki/Miles_per_gallon_gasoline_equi...). A tesla has 75 or 85 or 90 kwh onboard, so that's at most 3 gallons of gas! Another way to think of it is that mpg equivalent of evs is around 90-100 mpg. The model S is a huge heavy car, and look how far it can go on 85kwh.
