Home EV charging

[Midpack]

I don't have an EV yet but when I do I plan to just use the charger that comes with it and plug into the existing 110 V outlet in the garage. No need to upgrade unless you put on a lot of miles, I don't.

As long as you don’t drive more than about 30 miles/day that will work. Or you could find a fast charger on an exception basis, if you don’t drive more than 30 miles/day often.

My current daily average with the vehicle I bought in early 2022 is 15.1 miles. I'm definitely good for my normal daily driving, I just need a fast charger if I go on a road trip.

I think this is cool - EV charging through a smart meter socket adapter I.e. before the electric panel. It could be a cost effective solution for folks with < 200 amp service.So far it is Vermont only.

I'm guessing that if you have < 200 Amp service, the cables going to your house, the meter, and the transformer that feeds your house may not rated for 200 Amps, so that's not going to help - you still need to upgrade your service.

As ERD50 said.. it is the wire TO your house that is the problem, not your rating on your box...

Your box is supposed to be rated for that wire.. not the other way around...

You don't understand the product. It won't allow drawing more current than your service supports but will allow utilization of unused capacity. An alternative approach to the smart panels

I am not sure that will be a problem for the intended usage of this device. From what I understand the device senses the load and, if necessary, the device will cut off charging to the EV if the load exceeds what the service is rated for. When the total load drops and the demand sufficiently drops below the service amount, the charging resumes.

I’m not an electrician or electrical engineer so I could be wrong.

OHH, OK...

I had not read the review... if it only uses excess then it does sound like a good way to get what you need... and I assume it adjusts if something big kicks on in the house..

In the UK all EV chargers are required to use a “CT clamp” and limit the maximum current going to the house. Most houses here, including ours, are 240v with a 60amp fuse to the house, and an EV charger typically draws a maximum of 30amp (7.2 kW) but will cut back the power if the total current gets close to the 60amp maximum.

OK, I see now.
