FenrirIIIThe "standard" car charger is usually overkill—but your electrician might not know that [32:26]
blitzenI think “might be overkill” would be a better title and position than “usually overkill.”
There is absolutely a subset of EV drivers that could get by with a level 1 charger (ignoring time of day rates), but most people would fall behind anytime they drive further than the average number of miles. Sure, taking 10 hours to recharge your Chevy Bolt overnight when you’ve driven 40 miles is doable; 64 hours when you’ve returned home from a longer trip isn’t.
I own a PHEV, and installing a level 2 charge has been one of the best quality of life and financial changes.
fuzzzerdWhat kind of range do you have on that? I’ve been debating installing a l2 charger because overnight charging is usually good enough. I tend to get about 15-20 miles range tops on pure electric.
The way I explained it to my brother:
- technically just plug in to an existing outlet will work. Even if you didn’t keep up every day, you would get tot the weekend and make it up then
- but your garage already has a dryer outlet. Adapters are cheap and it will charge 4-5 times as fast
- but 50a level 2 charger is the same size as a stove outlet. Maybe a little longer wire run, and the “outlet” is more expensive, but it’s well worth the cost for the freedom, the flexibility, the convenience … and may even add to your house value
BuelldozerAs explained in the video you can’t run 50 amps ona dryer outlet. It’s 42 amps max.
RivalarrivalCan you cite a time stamp? I don’t want to watch a 30 minute video.
I’m very curious where “42 amps max” comes from, as NEMA outlets are rated for 15A, 20A, 30A, 50A, or 60A. 42A is a rather oddball number; I’d like some context for it.
Most dryer outlets are rated for 30A, NEMA 10-30, or 14-30.
Not the same person and cba to get a timestamp right now, but it’s the 80% rule - the electrical stuff isn’t designed to deliver the rated amperage continuously for hours on end, so for car charging, you’re apparently supposed to limit it to 80%. Now, 80% of 50 isn’t 42 but 40, so not sure if it’s a case of 80% not being a precise number or a mistake here, but it roughly checks out.
