Installed a 40amp car charger (slrpnk.net)

Installed a 40amp circuit for the EVs after charging a PHEV for 5 years and a BEV truck for almost a year on a single 15amp circuit.

50ft x 8 AWG x 4 wires isn't cheap ($1.32/ft with tax), plus conduit, straps, breaker, wet location boxes and outlet cover and the extra cost for an EV rated outlet.

Wasn't room between the post and the garage door king stud for a flush mount box, oh well.

I'll pay the electrician for a proper hard-wired charger when we upgrade service and run it from the main panel instead.

Really depends on how much somebody drives. I could probably squeak by on 1.2kw but the peace of mind of being able to crank it up to 11kw just in case is nice, doubly goes for the charger getting its own circuit. Typically I limit the charge to 2kw and the car is good to go overnight.

What size car battery have you? Mine is 64kw and I have a 7kwh charger at home. Overnight is ok but I cant imagine 1.2-2 being good enough.

77.4kwh iirc. The car doesn't get a ton of miles every day, probably no more than 8kwh on average. It's only when there's a trip planned that requires a full charge do I bump up the charger power limits to be ready in time.

Practical, sounds good

Slower charging is better for the battery anyway.
