1 Liter per second ~= 38.6 megawatts, for diesel.
I’ve never bothered paying attention to the flow rate in a fuel station, but it’s really fortunate that electric cars are fundamentally more efficient than combustion engines.
> Image result for gas station pump flow rate Light passenger vehicle pump up to about 50 litres (13 US gallons) per minute (the United States limits this to 10 US gallons (38 litres) per minute); pumps serving trucks and other large vehicles have a higher flow rate, up to 130 litres (34 US gallons) per minute in the UK. and 40 US gallons (150 litres) in the US.
So roughly 80 megawatts coming out of that diesel nozzle. Most impressive!
I've heard of CCS chargers in development that'll push 350kW (920V, 500A), which involves crazy stuff like liquid-cooled connectors. They flow 3M Novec through the cable.: https://ittcannon.com/core/medialibrary/ittcannon/website/li...
Pretty much any time fissionable material is moved probably beats it.
But yes, hydrocarbon chains are damned energy dense for chemical reactions.
Honestly one of the bigger issues is upgrading the electrical service at the depots to support the chargers. I worked on a prototype EV truck, and they had to software-limit the charger when first installed, because running flat-out it could draw more power than the entire rest of the prototype facility. They had to get the utility out to drop a new transformer before they could unleash the charger's full power.
The power you buy in a few gallons of diesel fuel is simply staggering.
