110 charging in the real world

No, you can replace the single pole breaker in the panel for an identical amperage double pole breaker. In this case being a 15a for safety. That simply doubles the voltage but keeps the same amperage which still doubles the wattage capable of being delivered because a lot of people don't know but the power that goes into your home is 240v but it gets split in half to 120 by a single pole breaker. But increasing the voltage and not the amperage is a free way of transmitting twice the wattage with the same awg. It's why powerlines are relatively skinny but can deliver a wallop of kilowatts. They are typically in the hundreds of thousands of volts but at a low amperage which then gets dropped down more and more the farther from the power station and closer to where it's to be supplied.

But there is a way to splice two completely separate 120v circuits back into 240v but that's kind of silly to me. But i can see myself doing that if i wanted some non obtrusive way of charging an EV or powering some kind of 240v appliance at a rental home with a dedicated laundry room and thus no 240v power in the garage without getting in trouble with the landlord.
I believe there are boxes you can buy that have 2 120v recepticles; you plug in 2 separate 120v sources and it outputs 240v. Or something like that. Personally, when I made the EV purchase decision, I understood that a dedicated 240v line would be needed.

I see, I guess this would work if the breaker is going only to one socket, instead of powering multiple sockets in the same room (or multiple bathroom with one GFCI).

Aside from the usual dryer and stove sockets, a breaker going to only one socket is uncommon, I've only ever seen it for large window/wall air conditioners that required their own circuit, and those are usually 240v anyway (and often not in a garage).

Yes it's why I mentioned having to find all the outlets that are fed by the circuit and either blocking them off entirely or just labeling it 240v only in my first post.
 
I have owned a 2017 Ford CMax Energi plug-in hybrid for six months now. It charges at home every night on a level 1 110 VAC charger. With the current warmer weather I am getting 25 miles to a charge, and it charges from 0-100% in five hours. Most days I work 6.6 miles from home, so the roundtrip is all done on 110 VAC charging. Other days I work 19 miles from home, plug it in to 110 VAC at work, and make the 38 mile roundtrip on those two charges. Some days I go to both jobsites for a 51 mile roundtrip. On those days I either stop at a level 2 charger for 30 minutes or just let the ICE start. My last fuel purchase was 27 March. I have 1650 miles on this tank of gas with just under half of it remaining.

Someone replied earlier that the answer "dependes upon your use case." This is a glimpse of mine, and 110 VAC charging works for me most of the time. That being said, I am going to install a level 2 charger in my garage to cover future needs. I also plan to see about plugging it in at the closer job to reduce my charging at home. Note that in six months of PHEV ownership I have never paid to use a level 2 charger, in spite of having used them at seven locations. Free level 2 charging is available if you take the time to look.

That seems a little sketchy to me. Those sources would need to be on separate breakers or no additional capacity would be realized. If those sources were on the same pole of the split phase, then a transformer would be needed to step it up to the required 240 VAC. It would be way beyond the capabilities of the average homeowner to figure out if two sources were on the opposite poles of a split phase system.
 
We have a home in Petaluma, 90 miles notrh, across the GG, in the wino country. If I drive the GS, which uses premium, it is gonna cost me $40. The V8 Tundra costs $50. Maybe more. The Model 3 Mid Range can do the round trip on one charge, which is fed with solar panels. My electric bill runs $9 per month.
 
I have owned over a dozen EVs over the years, but my wife and I especially like to use a 2012 Mitsubishi i-MiEV when it comes to driving around town in cooler weather (under 86 degrees).

No issues at all with Level 1 charging. However we do plug in our Chevy Bolt 5 miles away near a bank that is close to where the local retailers are. They offer 2 hours of free charging per session and we use multiple sessions since EVs are still kinda rare where we are.

A level one is fine for smaller vehicles with a smaller driving radius. Anything else you either need to supplement or upgrade your home amperage.

Your local utility may have a rebate program worth looking into.
 
Nothing. Gas stove, heat, hot water, and dryer. A few years ago I asked an electrician about upgrading the house to 200 amps to be able to support a dryer and stove and he ballparked $5-10K for the job.
That seems a bit steep unless you are a long way from the pole / transformer.

Question: MPH?? Charging? Explain. MW or mW per hour?

"
Our 2018 Model 3 Mid Range RWD charges at a whopping rate of 4 MPH on 110v. I had a NEMA 14-50 recepticle installed which delivers 30 to 32 MPH at 32A. The AWD cars can uses a little more amperage.
If you have an unused 3 prong dryer outlet, my understanding that delivers 20 to 25 MPH"

MPH is a rough charging speed that is displayed. It makes it easy for people to understand. Of course it is faster on a low battery and slows past, say 80%. Here is my screen charging at home on the NEMA 14-50 and mobile charger that came with the car. I just plugged it in and it is ramping to 32A. The car uses the internal charger at home but bypasses it and uses the Supercharger charger when charging at a Tesla Supercharger. Much faster. I think I got 80 or 90 miles in 10 minutes (maybe 15?) or something like that.

Around here the utility is responsible for everything to the meter base (if underground) or the weatherhead (if overhead)--there wouldn't be any additional cost from the electrician for being a long way from the pole / transformer. As far as I recall, there wouldn't be any from the utility either if there's already an existing service.

MPH is how many miles of range you gain on a charger. My veicle gains 5 miles per hour on a 110 VAC home charger and 10 MPH on a 240 VAC level 2 charger.

EVs and PHEVs have a battery acceptance rate measured in killowatts per hour. My car has a very modest 3.3 KW/H acceptance rate. True EVs like the Tesla Model 3 have far higher acceptance rates and can gain over 30 miles of range on a level 2 charger. They also are compatible with level 3 fast cgargers that can deliver 350 KW/H. Understanding battery acceptance rate is key to any decision on joining the ranks of EV owners.
 
I ran into a guy who seemed very level headed. He said he only uses 110-volt charging at home for his Nissan Leaf, which he supplements with commercial chargers when roaming further afield. For those who do this, what's the real-world performance you are getting from 110-volt charging at home? One reason I ask is that our 160-year-old house only has 60-amp service, and the cost of upgrading that plus significant rewiring would be a big hit before we could even consider installing a 240-volt charger. Another reason is that places I frequent have no chargers, but it would be possible to plug in to 110 at some of them.
Was that person me?!

110v 20amp circuit, 1.4kWH charger charges at about 4 miles per hour. Bought the car believing I'd add another 220v outlet in the garage, but I never had to.
 
Ah thanks - makes sense.

I can tell you a 2022 Leaf charges very slowly on 120V. A couple days until fully charged.
This is a misleading statement. The car is not at 0% every time you plug it in at your house. After a usual day of driving my leaf was fully charged in 4-5 hours. But yes, if it were at 0% battery it would take almost 2 days to charge on 110/120.

OK my rental Leaf was around 15% and it took until at some point on the second night at my brother's house to come close to full charge.

The previous renter was supposed to turn it in above 85% charged, that didn't happen.
 
Yes. That's how it's done. Something like this.
Thanks for sharing. I think it's kind of silly, but then I know how to add circuits to my house. One would need to try multiple outlets in order to find two on opposite poles of the split phase. After that, one needs to consider how may homeowners understand ampacity vs AWG and the distance limitations. 12 AWG extension cords would be needed to safely implement that solution, but most are 14 or 16 AWG. I imagine that the non technical users of this device are going to have some hot extension cords if they don't read the directions carefully.

I'll be running 6/2 AWG copper to the garage for a distance of under 40 feet using a 50 amp double pole breaker. I have reason to believe that on Father's Day I will receive a level 2 charger. Not sure if it will be a 7.2 or 9.6 KW model, but I will be wiring for the latter.

Yeah, I tell people if you are gonna own an EV, understand all your needs and requisite costs. Do it right and do not underestimate things. I think this type of solution is a kludge at best, but I know very little about this stuff. I had a union electrician run 60' of #6 copper to the garage. $600 all in, including tip. Wire was expensive, like $200.
