Home Charging Solutions

Home Charging Solutions

Although it would be nice to install a charging station inside my garage, I don't think that is going to work for a variety of reasons. Has anyone looked into alternative solutions that would be appropriate for an outdoor residential installation. I think GE offers a charging station, but it looks like it might be only for commercial applications. The on-line Tesla Shop indicates that information regarding the home charging connector for the Model S will be released at a later date. Has anyone heard whether they are considering an outdoor unit?

The charger is supposed to be ok indoor or out. It can charge up to 240V at 80 Amps. This counts as a level 2 charger or you can do like dad did to get me to visit and put a NEMA 14-50 plug with ground down outside with a cover.

Just curious why you would wan a home charging station? The battery pack does best with slow charging so I would think that a 220 outlet would be plenty to keep yoru car topped up at minimal cost.

My local electric company, after confering with Tesla, recommended a single phase, 240 volt, 90 amp instalation. That can be done indoor or out.

I'm pretty sure you can tell the car to draw less than the available amps, so the home charging station just provides a way to fast charge when you need it via a purpose built device.

When don't need the fast charge (90% of the time for me, for instance), then just tell the car to charge slowly. =)

Hard part will be remembering to flip back and forth.

My local electric company points to this for charging station installers - I found it to be very useful in understanding a lot of this:

In Europe(Belgium) we have 3 phase 220V 32A. I think I will use that to charge.

Thanks mklcolvin. That is very helpful.

@ steven.maes yes I have the plug already installed in my garage
on advise of a Tesla Rep here

+1 mklcolvin. Thanks for the link.

Just curious: why is the in garage charger undesirable? Other than possibly a slight increase in insurance, I can't come up with any viable reason to not have a charger inside the garage.

Unless you don't HAVE a garage. I think I could see the problem there:)

The battery does best over a long period of time with slow charging. Thus a 220 or even 110 circuit will work for most situations very well. Tesla says the more high speed charging done, the shorter the battery life. Unless you are driving very long distances every day and need massive amounts of charging, it seems to be counterproductive to install and use a high power charger.

Thanks for all the responses. They were very helpful. In response to Vawlkus, I am usually first out in the morning and last home at night, so getting the Model S into the garage every day would involve moving my wife's car, which is not very practical. It sounds like a 220volt outlet installed outside will work nicely for our situation.

As I will be re-furbishing my garage in the next two years, I'm also planning using a 220 to charge. My concern is that the outlet is at the nose-end of the car, and I want to mount the charging cables thru my rafters and have the two ends drop down for use. I'm not sure if the default charging cables are long enough.

The ambulances at the hospital I have worked at have retracable cords mounted on the ceiling that eject when the vehicle is start. That would be a cool home charger setup. The only thing to remember is to plug it in.

Either way I will be mounting the cable across the ceiling and leaving it dangle about 2' off the floor on a bungy cord.

Vawlkus | 19 April, 2012

Um Sindell, the Model S plug in is behind one of the rear tail lights, not up front like the Nissan Leaf.

As for the degradation of the battery due to high charging, that's the high speed DC charging, not the home charging options. Shunting 60 - 85 kwh into a battery in less than an hour is what ages a battery :)

One reason to have it outside is so I can charge my Model S in your driveway when I'm passing through town. ;-)

I'll happily return the favor.

NJS1207 | 19 April, 2012

It's a deal, MandL. Mi charger es su charger.

I plan on charging in my garage with 220. I wanted to have the charging cable hang down from the rafters, but realized that the garage door (which is the typical segmented overhead variety) would get in the way. Perhaps a 'boom' sticking out of the sidewall of the garage just below the level of the garage door will allow the charging cable to effectively drop down from the 'ceiling'. This way we won't trip on it, and we can still walk by the Model S on that side while charging.
