Model Y LR Seven Seater RED
I just received my P85 I purchased used. Electrician working on getting my HPWC installed. However, I tried using my Chevy Volt 240V charger using the J1772 adapter. The car says starting to charge then says stopping charge. Am I doing something wrong? I'm I supposed to change something on the car. Since I bought this car used I haven't had anyone go over the details with me.
 
Did you have a Tesla delivery specialist go over the details of the car with you when it was delivered?

What messages (if any) do you see in the car when you try to charge?

You can always call Tesla Service, and they can pull up the telemetry for your car while you are on the phone with them. They should be able to tell you what is going on.
 
Congrats on your purchase! I agree Tesla service / roadside assistance should be able to help you, but here are a couple DIY things to look at:

* When it stops charging, what color is the lighted ring around the charge port?
* You can tap the battery icon at the top of the 17" screen and set the maximum number of amps that the car will pull from each charger. Try reducing it by a couple. It's possible (although I think unlikely) that the car thinks it can draw more power than it should.
* Take a look at plugshare.com or recargo.com to see if there's a public J1772 charger nearby. If one of those works then you can likely rule out a problem with your J1772 adapter.
* If you have a standard 110-120V outlet nearby, try that too. If that works then most likely the charge port and charger internals in the car are ok.
 
No I had it delivered by a Shipping company out of NJ. Bought it direct from an owner. I think I got it working. On the screen it says max 15A when I decrease the amp to 10 it starts charging and says full charge in 11.5hrs. My HPWC should be up and running in about 1 hour. The electrician is finishing the install as we speak.

The charger I'm using is the 240V for the Chevy Volt I think its a 40amp circuit.

Now to figure out the rest of the car.

The Volt charger can't go over about 10amps so you have to keep it around that level.

First, change your screen from 15A to 40A. Secondly, before spending money on installing HPWC, ensure that you have dual chargers in your P85. If you do not have dual chargers, you are wasting your money on HPWC, as HPWC charges at double the speed at 80A, in that scenario you want to change your screen/configuration from 15A to 80A, but ensure that you have at least the capacity for 100A on dedicated circuit to your charge port. Hope this helps.

Actually, having a dedicated HPWC is a good thing even if you only have a 40 or 50 Amp circuit. This is because it's hardwired so there is no stress on the connector between the UMC and the NEMA 14-50 (or what ever you might have). Also, there is wear and tear from plugging/unplugging the UMC. There have been cases where the UMC/14-50 connection has had heating problems and damaged the connectors. It's not clear if the recent garage fire was caused by that. I think the hardwired HPWC is the safest approach.

As for the hanger. I'd put it where it will be the least likely to get banged into. Hard to tell where it is from your pictures. I have mine mounted between the two garage doors and park nose in so that the charge port is about 3 feet from the HPWC. I have the hanger right below it. FWIW, you will never get the cord and plug to hang nice and neatly just with the standard hanger.

I only have 80A for my HPWC so am limited to 64 Amps charging. This is still pretty good.

HPWC from Tesla does cost some money. As for charge port, it should always be a dedicated (hardwired) connection.
Please go through the forum, there is seldom a need to plug/unplug the UMC from charging point at home. I am sorry, but I do not understand your point with plugging/unplugging. Are you talking about power source or cars Chargeport?

Guys, to avoid confusion, you all should stop referring to the above units as "chargers". They're EVSEs.

See diagram at My Nissan Leaf Forum View topic - Range issues. Even though that's for a Leaf, the principles are all basically the same. For L1 and L2 AC charging, the charger is on-board the car. The UMC, HPWC, whatever the OP's using from his Volt are all EVSEs. You'll notice the C in UMC and HPWC does not stand for "charger".

You'll also notice that at Model S Design Studio | Tesla Motors, when you select High Power Home Charging you get:
Outfit Model S with a second onboard charger and install the High Power Wall Connector in your garage. This combo lets owners charge quickly at home and ensures your Mobile Connector is always in the trunk for charging on the go.

For Supercharging in your case (CHAdeMO on the Leaf) DC FC, that charger isn't on-board the car.

I've posted My Nissan Leaf Forum View topic - Talk to me about charging/EVSE and charging stations and similar posts numerous times so people can get the terminology straight and have a better understanding.

Artsci, we have no idea which EVSE the OP is using w/his Volt. Are you telling me it's a 10 amp @ 240 volt max EVSE? If so, that's pretty lame. I've seen Volts charging using the Chargepoint EVSEs at my work pulling ~ 3.1 kW (or was it 3.1 to 3.3 kW?) @ 208 volts, so 10 amps @ 240 volts is only 2.4 kW, which would be lame.
