Oh, I see; the 1000 miles/hour is the rate at which driving range is being added. That sounds impressive because it has never been an issue how quickly driving range is added to IC cars when the fuel tanks are being filled. It's just another bogus stat to make electric cars seem impressive.
So, in the way of comparison:
High speed diesel fuel dispensers operate at 23 gallons/minute (1380 gal/hr), so when I am filling the tank in my diesel pickup, which gets 17 mpg, I am adding range at the rate of 23,460 miles/hour. (And this number is easily changed by increasing the flow rate of the pump; I have seen references to fuel dispenser flow rates of 60 gpm.)
See, diesel fuel is 23 times better than electricity!
OR,
What is the flow rate of potential energy when I am filling my tank at 23 gpm? Diesel fuel density is 7 lb/gal, so the mass flow rate is 161 lb/min. Converting to metric, that is 73 kg/min. The energy content of diesel fuel is typically 43 MJ/kg, so the energy flow rate is 3139 MJ/min. Converting to kilowatts: 3139000 kJ/min x 1min/60sec = 52317 kW. This is 209 times the energy flow rate of the Tesla V3 charger.
