It’s almost not worth the hassle for level 1 charging because it’s so slow though. Might as well put in a level 2, and even then, you’re not often charging every night unless you’re putting serious miles on your EV daily. I’d say one level 2 charger for four occupants/EVs would be reasonable.
If everyone trickle charges every day it’s make a more even draw from the gird which is easier to supply. The equipment is also cheaper for the car/parking space owner.
It is my understanding that “level 1” charging is 110V 12A 60Hz AC? AKA just plug it into a normal residential wall socket like a toaster? I wonder which one presents more of a load on the power grid, charging an EV like that overnight, or owning a water bed.
Usually yes, level 1 is plugging into a typical 110V socket. You can also adjust the amperage draw on some chargers. I can go from 6 to 12 A in 2 A increments on the one that came with my ioniq 5.
Level 2 is 220V and 25-80 A (<20kW).
Level 3 is technically anything above 20 kW, but usually 50 kW is the floor. These are the EV-specific fast chargers or Tesla’s Superchargers.
An EV on level 1 (or 2) is a continuous load, so I’d imagine probably easier to handle than an intermittent load.
