2400W x number of occupants is still some series draw on their main panel.
Their point still stands that their mains would need an upgrade.
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.
Electrician here, no it would not need to upgrade your panel to add a charger. If you have an intermittent load, like a car charger, you can add it on to your panel provided you don’t run it along with your other high power, intermittent loads (clothes dryer, oven).
You literally can not charge a car 24/7, so if it is not a continuous load…
Im west coast Canada where central heat is more of a new home thing, every previous home has baseboard heat in every room. This is true in condos and town homes also. So every winter the grid handles every non new single family dwellings use of baseboard electric heat. I don’t see this being an issueto have an EV that can charge in late hours or at lower draw if needed
When I saw this post, I also thought about places like Camp, California, who weren’t so lucky in terms of having a safe electric infrastructure. I imagine it might be trickier to shift over in those types of areas.
It’s awesome that they managed that in BC. I hope more places gain that kind of stability.
