Anyone using Charging Stations?

Anyone using Charging Stations?

With the recent news of a garage fire from a bad connection and with news of the UMC connectors melting, I've been doing some more reading. Some have suggested having the car outside to charge and others have said to use the HPWC from Tesla. I've started to look at the Charging Stations from BOSCH, GE, and Siemens. Wanted to get a few suggestions forms others. Electrician comes out next week to install an outlet. So anyone using a wall charging station other than the Tesla model?

Leviton makes a variety of chargers for home use. I've had mine for about 15 months with no issues.

Where have you heard these suggestions? I prefer to charge inside.

We used a NEMA 6-50 before we got the HPWC. That is more than adequate for overnight charging as long as you have a competent electrician and tell them what your household power load is, what your breaker box is capable of and provide them with the information supplied by Tesla. If you don't know what to tell them about your breaker box you can send them a photo. They will want to know if you have electric heat, an electic stove, electric dryer, etc.

Check out your contractor through your state licensing agency to see if there were any complaints about their work. Make sure that they apply agree to apply for all necessary permits and that the work is followed up with an inspection from your local regulating agency. Verify that permit fees are included in the bid.

If you want a fancy outlet that can be used by all EVs you might look into the Clipper Creek products with a J-1772 outlet. They the best that I know of for AC charging.

Another idea would be to dial down the amps. I used to use a 40 amp circuit of unknown quality and manually dialed the charge down to 24 amps. The same as would be pulled from a 30 amp circuit. I have since had an HPWC installed.

I use a Nema 14-50 and it meets code for electric vehicle charging.

I just got the latest 5.8 patch and if the car detects irregularities in the power quality, such as you would get in an overheat, it deals back the current on its own.

Not worried.

A J1772 EVSE is a pain to use, since you have to use the adapter.

I initially noticed higher temps at the Nema 14-50 connector on the wall, I had my electrician come and redo the wiring since the standard recommends a higher gauge wire. I updated the wiring with a lower gauge and it reduced the higher temps at the wall.

Make sure your electrician knows that, whatever you install, it will be a "Continuos Use" circuit. I beleive if the circuit remains energized for more than 4-hours on a normal basis, they have to install wiring and circuit breakers rated for that type continuos use circuit according to NEC code.

A J1772 charger isn't a bad idea, but the one negative is that you can't pop open the charge port from the charge cable. Although lolchampcar is working on a solution for that.

The 50 amp plug on the travel cord works great. The HPWC also works great. I have used both and find for most people the 50 amp is really all you need. The HPWC is almost over kill unless you drive over 250 daily miles.

I have two blinks in the garage I used with Leafs before the Tesla. I stopped using them pretty quickly after the Tesla's arrived. You have to manually open the charge door from inside the car and when you unplug you have to release the charger cord from the adapter then pull the adapter out manually with only a small surface to grab onto.

The Tesla charge cords are designed to work with the Tesla and are super simple. Push the button on the end of the cord and the charge door pops open. Push the button to unplug and the cord releases with ease. If the car is locked you may have to unlock to release the cord ( I leave auto present handles off because I hate to wake up the car every time I walk by in the garage). Also with the adapter the cord sticks out further from the car increasing the chance of bumping into it walking by the car.

With Tesla there is no reason to buy a charger. Total waste of time and money.

My wife and I are both driving our cars in and out of the garage numerous times during the day. We may each plug in and unplug 5 or more times in a given day. We are just in the habit of plugging in every time so we don't forget and the cars always charged to 80%. The Tesla cords make this a two second process.

There is no reason for any other charge equipment. We have been charging EV's in the garage since 2010 with zero issues. Just like with all electrical circuits make sure they are properly sized and properly circuit protected. If you are worried about fire install a smoke detector in your garage. I do have monitored ADT smoke detectors in my garage.

I have a 40amp dedicated line into my garage. I have a Leviton J1772 (from when I had a Leaf) and a Nema 14-50. Both work fine with the Model S.

edcalis | 24 décembre 2013

I am using a GE charger, installed way back when I had the Volt. It worked perfectly, and still does with the S.

meespiri | 24 décembre 2013

To golftoday, Iam planning to do the same setup. Is your nema-14-50 a separate dedicated 50 amp breaker switch from your J1772? What is the breaker switch amp on your j1772?

If you are stuck, if you have lots of time, otherwise waiting hours to charge makes public charging stations something I don't think about because I see them as useless.

Mhotep | 24 décembre 2013

Thanks for the input everyone. I think I will push forward with using a charging station between the model s and the outlet. Main reason is cover with the USB and stress to it over time.

Have a Nema 14-50 installed meeting the specifications and got the 5.8.4 update yesterday.
Charging inside.
Why would i put my car outside to recharge?
Trust the system considering I meet the specs.

I bought this Siemens unit from Amazon:

I have a NEMA14-50 receptacle in my garage and had the electrician put a NEMA 14-50 plug on the Siemens unit. We needed a Level 2 charging station as we also own a Leaf. The nice thing about this unit is that you can take it anywhere. You could even plug it into an RV receptacle. It has essentially become the equivalent of a Model S mobile charger for the Leaf.

Mhoptip. I thought I would use my charge station also but dumped them both for the Tesla cord within a few weeks. Save your money and don't buy a charge station until you have used the car for a few weeks.

A charge station serves no purpose with a Tesla and just gets in the way.

If you insist on a charge station hard wire a HPWC and set it for the amps your house wiring can safely deliver. Third party chargers are a waste with a Tesla. They provide no value and just make charging less convenient.

I'm using the Leviton EVB40-PST 9.6KW Charging Station primarily for comes with a 15 foot cord so I don't have to pull mine out every time I get home. I didn't go with the Tesla model because I wasn't going to do the 80-amp to really take advantage of it and just in case we ever get a different (i.e. non-Tesla) EV, it has the more general J1772 connection. We have a 2-car garage so I put the Leviton on one side and have a 40amp 240vac outlet on the other side...they are on the same circuit as we only have the one EV right now so I'll either be using the Leviton or the outlet, but never both.

I have used both the Nema 14/50 that comes with the car and the HPWC . Plus nearly every other combination. We use the HPWC every day except for trips . The advantages are numerous. 1 the HPWC gives you access to plug in your car any time even with out you key in your pocket. 2, the HPWC as mentioned by others allows variable charging options . 3 The HPWC has a lot of tech inside that protects your car and your electrical systems such as variable power settings and fusing options all too make your experience a safe and easy one. Lets face it you no longer have to frequent the ARCO log jambs or wait in line at the Mini Mart. Step up to your new way of living use the Tesla stuff . My Christmas list has a variety of adapters for my togo bag to match even more situations safely.

Just a hint we all have more to learn about charging coming soon watch your updates. Tesla is taking care of you and your amazing electric car!

Hire an electrician and ask that he/she have a second person look over the work. I personally looked over the work and he did an excellent job. (My degree is electrical engineering so I was a good candidate to look it over myself.)

We ran thicker gauge wire and put all the wiring in industrial conduit that is completely sealed all the way to the box. We also used a brand new circuit breaker and make sure the everything was double-checked.

There will be more garage fires but that doesn't mean your house is more at risk. Basically, you can't apply statistics if you're just looking at total garage fires vs installs. There are many more factors that need to be considered.

The dedicated 240 40 amp line comes into a junction box in the garage. It then splits to the Leviton J1772 and to the Nema 14-50. For me, a 40 amp line is more than enough. I easily charge to whatever I need overnight . I've never had the problem of not being able to charge fast enough with the Tesla. I did have that issue a few times with my Leaf. Sorry, but I don't have details on the breaker.

I have an OpenEVSE that I built and installed for my car (with dual chargers) and my wife uses the standard Tesla charge cord plugged into a NEMA 14-50 (the socket for which I installed).

The key to all of this is that resistance makes for heat. If the wire gage to the plug or the quality of wiring at the plug is not up to par, you will generate heat. Too much heat means melting and even more leads to fires. It is not clear to me that the UMC has any issues at all as all the melting I have read about has been at the plug adaptor leading me to suspect the plug. I say this because, if there was a conductor size issue leading to over heating in the UMC, it would be there for all of them not just a select few. This does not rule out a manufacturing defect.

In short, feel around your installation periodically though out a charge session. If things are getting warm anywhere (or you get shocked), stop and investigate. If it is getting warm enough to melt something, you'll know it straight away.

Lastly, the door popping key fob is done :)

My electrician said splitting the line between a nema 14-50 and anything else is not to code- that each charging system needs its own breaker.
