110 volt charging

Compré un SPLITVOLT que usa mi toma de 220 V (la de la secadora) en el garaje. Esto me da un nivel 2, aunque un poco menos potente debido a un margen de seguridad, pero mejor que el nivel 1. Así evito gastar miles de dólares en que un electricista instale una toma de 220 V adecuada. Espero que esto les sirva.

If I have it, that's perfect—no problem.

I purchased a SPLITVOLT which uses my 220 (dryer plug) in the carport. This gives me a level 2 but slightly less due to a buffer but better than level 1.

That is definitely L2 charging. 240V is L2... doesn't really matter what the amperage is. I carry a 16 amp L1/L2 EVSE with me when I travel. I could get away with 16 amp L2 charging at home almost all the time, even though I drive between 150 and 200 miles per day. On a dryer circuit, you can (and probably do) charge even faster (up to 24 amps).

Most people can plug in for about 12 hours a day at home. At 16 amps, that's about 40 kWh into the battery. Even in the winter, that should be over 100 miles in a Mach-E unless you're really hauling on the highway. In the summer, I could go about 180 miles on 40 kWh.

There are some other solutions for L2. For instance, if you have a dedicated 20 amp 120V receptacle (which is common in a garage or on the outside of a house), you can usually just connect it to a 20 amp 240V breaker and put a NEMA 6-20 receptacle in. The wiring is the same for 20 amp 120V and 20 amp 240V. You don't need a neutral for EV charging. You should wrap the last few inches of the white wire in red electrical tape so it is obvious that it is now a hot line. If you are not comfortable doing this, I would certainly get an electrician to do it. FYI, a dedicated receptacle means that it is the only receptacle/device on that circuit. Don't do this unless you are certain.

This has been said before, but worth repeating:
120V charging will cost you 15 to 20% more in electricity usage compared to 240V charging of 32A or more.

That is true, but for someone who drives few enough miles that 120V charging works for them, it would take forever for the savings to equal the average cost of an L2 installation.

Let's say they drive 20 miles per day, average 3.5 miles per kWh, and pay $0.20/kWh for electricity. After five years, that would be 36,500 miles. They would have used 10,428 kWh. That would cost $2,085 in electricity. So, if they spent 15% more on wasted energy to charge on 120V, that would be an extra $312 over those five years.

EDIT: Don't get me wrong -- L2 at home is ideal. If it doesn't cost too much to install it, that's what I would recommend. However, not everyone needs it, and the cost doesn't always make economic sense. When I was doing L2 installations, my favorite part was figuring out how to make a difficult home installation work for the least amount of money. In most commercial installations, they didn't care about any of that. Those installations were boring to me.

Correct. I wasn’t trying to say that no one should use L1 charging due to it‘s lower efficiency. Only that should be one of the factors to consider.

LOL I'd be lucky to break 10,000 mi in 5 years. City Condo, everything is nearby.
I typically do an 80% DC Fastcharge when down to 20% - about 4-5 weeks apart.
