Best installation of 2 ev chargers in garage?

Getting 2 nema 14-50 outlets 40amps installed on my new build. Builder is charging me $530 each. Which seems like a good deal to me. But I won’t own an EV for the next 5 years at least. But would like to future proof. The garage is double car garage. We usually back in our vehicles. But can drive in if necessary. What would the best placements be for the outlets?

I'd suggest near the garage door. This allows you to charge outside as well, running cord under the garage door. If they will put one on either side is good. If you've got two garage door could install them in the middle that would be the most flexible option.

I'd also insist on 6 guage or larger maybe even 4 as this will allows you to install a higher amp charger if you wanted. Builder will use smallest wire they can.

Pretty sure they would just say no about larger gauge. And it’s only a single door double garage. But I attached a pic of the garage. Best to install which location red or blue?

Rough in conduit to the front and rear, if you're future proofing 5 years out, you minus while go for it.

Why would they say no? You're the customer.

6AWG is better for future proofing as cars are constantly improving their battery capacities. Larger battery EV's charge at 48A, so you'd need a 60A breaker and 6AWG wire. Currently there is no EV that can charge at 80A to require 4AWG wire, that was once upon a time when older Tesla Model S/X's had dual on-board chargers but they don't carry that feature any more. Where you place your chargers should depend on what vehicle you intend on getting. Some cars have their charge ports at the very front, some have them at the far back. If you back in and your charge port is at the very front, that's not very intuitive. I personally have mine 3/4 away from the garage door to the wall and it reaches the cars parked outside no problem.

In order to even charge at 48A, you'd need an EVSE, not a 14-50 outlet.

This^ Personally I would wait until you get your EV car in the future before you decide on this. I've bought a new build and had 200A circuit. It was an easy run for the tech and they charged me $700 (although I got a MY LR and my wife was adamant about buying the Tesla Wall Charger). So the tech ran the wires to my point of selection and installed the wall charger at 48A. With the cost of technician, the inspection was included as well.

Right now we moved into a TH closer to my work, so I've relocated the TWC to this house and since we only have 100A circuit, we can only use up to 32A on the TWC. Which now is perfect because my Jeep 4XE charges with the wall charger (adapter needed) at 32A.

I have a new build with a garage similar size to yours. The widths of these new build garages car hardly be called a two-car garage; especially ones with side entries. The stairs takes up about 2-3ft of space leaving you with effectively ~14-15ft to squeeze 2 cars. As for your placements, they look fine.

The builder replied, they will see what the gauge of wire is. But they can also upgrade from 40 amps to 50 amps for additional $433. Is it worth it?

if it's my new built I would go for the 50amp, these things tend to cost a lot more to retrofit after the fact.

So I might be the minority here, but if you are planning to park your EV inside the garage, I would actually install one of those chargers in the front of the garage. The reason is that if you want to come from the house through the garage and go out the garage door, that charging cable you have to step over is a tripping hazard.

We have 3 EV chargers (2 x 14-50 receptacles and a Tesla Gen 2 Wall Charger) and they are all on the wall with the garage door and I had the same idea that I could charge outside or inside. I have yet to ever do that, but even if we did, only really would need 1 of them to be able to do that. While I am careful about the cables, I am thinking of relocating the ones closest to the house entrance door to the front wall so we don't have to step over the wires to get out of the garage doors. As they sit currently, we have bikes and stuff that need to roll over the wire if a car is charging. If the charger was on the wall in front, it would avoid the ancillary traffic.

Our EVSEs just plug into the 14-50 receptacles and our PHEV's limit the current draw, but our TWC is hardwired and charges at 72A.

My thought would be that the location by the porch/foyer is not ideal. You’ll be at risk of tripping over plugged in cords or simply be annoyed walking over them every time you enter/exit the house via the garage. Think about stepping over a cord every time going out to shovel the driveway in winter, putting out garbage/recycling, using the second vehicle on the other side if the first one is still plugged in, etc, etc.

The location for one opposite side near front of the garage is fine. This location can service a vehicle inside the garage or a vehicle outside the garage without the need for a mega-long cord. And it won’t be in the way of regular foot traffic coming/going via the garage.

In lieu of the porch/foyer location either keep it on that wall but move it closer to the 45 degree jag - or - my preferred suggestion would be along the dining room wall in the centre. The centre location would be convenient for charging a vehicle parked on either side of the garage. It will also be flexible to charging any charge port location without draping the cord over a vehicle. There’s no standardization of charge port location so a centre mounted cable can easily be plugged into a port on the left/right/center of a vehicle in either parking spot.

Take a minute to consider the charging port location of some of the current crop of EV's:

Kia EV6: Rear Right corner
Ioniq 5: Rear Right corner
Mach E: Front Left fender
Teslas: Rear Left corner
Porsche Taycan: Front Left Fender and Front Right Fender
Nissan Leaf: Front Bumper
Rivian: Front Left Fender
F-150 Lightning: Front Left Fender
VW ID.4: Rear Right Quarter Panel

You'll notice that most of this list is front left or rear right. There is really only a couple outliers doing something different - Tesla and Nissan.

I consider front left and rear right are somewhat interchangeable, because in a garage you can pull in frontwards or backwards, which puts the charger at the same location in your garage when you pull in. So considering that, what I'd suggest for the left spot, is that you put the charger on the left wall to the north of the door. The charger for the right spot is in a good location already.

If you had for example an Ioniq 5, you could then pull it in backwards in the left spot, and it would be lined up with the charger. In the right spot you could pull it in forwards, and it would also be lined up with the charger. If you had a F-150 lightning, the reverse would be true. Pull it in frontwards in the left spot or backwards in the right spot.

just an FYI, a 17 ft wide garage is tiny... you should see if you can increase the width.. You can only fit two cars in there, and there will be zero room for storage on the sides..

Mine is 18' and I can get 2 SUV's in, but one I have to park very close to the wall on the passenger side.

17' would be really tight indeed unless one was a compact car.
