Where did you pull that 1440Wh number from? The battery in my plug-in hybrid is 20kWh, and that's still small compared to a full EV.

Ah shit, I googled the number but it looks like I got the number for a battery in an internal combustion engine car, apologies. I'm an electronics person, not a car person

Understandable. Just for the sake of comparison to a smartphone 120W fast charger, level 1 EV chargers (which can still take days to fully charge a completely drained EV) will generally deliver between 1000 and 1500W. Level 2 (the fastest you'll typically see installed in people's homes) range from about 7kW to 19kW. Level 3 fast chargers typically operate from about 60 to 250kW and unlike level 1 and 2 which deliver AC to the car to be handled by the vehicles internal rectifier/charger, level 3 delivers DC.
