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).
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.
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.
That seems a bit steep unless you are a long way from the pole / transformer.
Yes. That's how it's done. Something like this.
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.
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.
Was that person me?!
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.
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.
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.
