    I 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.

      Yep the difference for our setup was going from 12-18 hour full charge times (Level 1) to about 6 hours on Level 2. L1 charger could only put out 12 amps at 120v, and while the L2 charger can do up to 50A of 240v power, our vehicle can only use about a third of that capacity at max draw.

      So as the video’s topic covers, we didn’t need a 50A circuit for Level 2 charging on our limited vehicle. But I put in a full 50A circuit anyway so now I can eventually upgrade our other car to electric or PHEV and be ready for whatever those need.

      Agreed, and that headline is needlessly inflammatory . Looking at my EV mileage , I could almost certainly get away with just plugging into a standard outlet. However the level 2 charger means that even if I screw it up, I can be mostly charged in a couple of hours. It’s been really effective at helping me get over what range anxiety I had. It’s really helped keep car usage as a somewhat impulse thing, rather than a process: I’m ready to go anywhere anytime.

      It also means I can charge multiple EVs, if I wanted to.

        If you screw up, you can usually get to a charger a few blocks away and snag 50% of your battery in 20 minutes.

        I charge entirely off of a standard 120 outlet, and it easily handles my daily and weekly travel needs, along with my partner’s numerous errands and extra trips throughout the week.

            Gonna go out on a limb here, and guess that people living in a cabin where the electricity only works a few hours a week aren’t going to buy an electric car.

            As for access to public chargers… I just spent the weekend in a rural area and had no problem finding a charger within 20 miles of me.

      What 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

            I believe dryer outlets are typically 30a@240v. That’s a nice step up than a standard outlet and simple math shows 4x the power of 15a@120v

            If you have one in your garage, then you already have an outlet that can do faster charging than a standard outlet.

            Just like you technically don’t need a 50a level 2 charger, you may not have to settle for a standard outlet. I bought a heavy duty extension cable with adapters for several different outlet types.

            Can 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.
