Charging my Y with a NEMA 14-50

[SCYC]

Just got my new model y, had a NEMA 14-50 outlet installed, 220 V/40amp, in my garage. Its been charging at ~32 m/hr, was expecting about 20 m/hr, has anyone else seen this charging rate with a NEMA 14-50?

What voltage does it say on the screen when it's charging?

 

[Feathermerchan]

30 mph is about right at 40A. I used to charge that fast but discovered I didn't need to so I turned it down to 30A.

The Tesla website for the NEMA 14-50 adapter shows the Model Y charges at a rate of 29 mi/hr so you're doing pretty well at 32 mi/hr.

This is the normal charging rate. You are using the include UMC mobile charger and plugging into the nema 14-50 outlet, correct?
Also be aware that your charging rate will slow down as the battery nears full. This is automatically adjusted by the vehicle.

I am almost always exactly at 30, although I have seen higher (I think the highest I've observed was 33). The only time I remember seeing 29 is when I first the car and first plugged it it, but it went to 30 within a few minutes.

 

[Klau2]

the UMC mobile charger is max at 32 AMP. I use a ChargerPoint HomeFlex at home at 40AMP and gets about 37/38 mi/hr with it.

I get 27mph on the mobile charger with the Nema 14-50.

We have a fairly high load on the panel so that's acceptable to me.

No Im charging at different rates dependent of temp and how close to the end.

keeping the NEMA 14-50 plug plugged in to the power receptacle.

When not charging the vehicle I keep the plug from the Tesla mobile charger plugged in to the power outlet (240volt)

Anyone think thats an issue?

 

[Feathermerchan]

Nope. That's the way its meant to be.

It looks like you have the performance model, so that mphr is going to be less since the overall range is less with the same battery pack.

I am having a NEMA 14-50 outlet installed in preparation for eventual delivery of my Y. I plan to use the mobile charger that comes with the car. Do they supply a 14-50 adapter plug with the mobile charger?

 

[empiredown]

No. You’ll need to source that separately...

$35 at the Tesla store.

 

[Feathermerchan]

FYI I used a 6-50 because less wiring. Works just as good as 14-50.

I saw this on the Tesla web site. Has anyone seen faster charging with this cord vs standard cord with adapter?

The Corded Mobile Connector features a NEMA 14-50 plug and improved charging speeds (versus standard Gen 2 Mobile Connector with NEMA 5-15 adapter).

Compatible with Model S, Model 3, Model X and Model Y.

Includes:

1 x NEMA-14-50 corded mobile connector (with 20’ cable)

The Tesla website for the NEMA 14-50 adapter shows the Model Y charges at a rate of 29 mi/hr so you're doing pretty well at 32 mi/hr.

The Corded Mobile Connector can do 40A, the Gen 2 and newer can only do 32A even with the 14-50 adapter. The original Gen 1 Mobile Connectors could also do 40A (I have one of those I bought of eBay). It is no longer available and used different adapters though.

I get 35mph at 32 amps on my Model 3 with the portable wall connector -- so 30 mph sounds a little low to me.

It’s a function of voltage, which can range from 230 - 245 volts (or thereabout) depending on your home, the local grid and your proximity power generation facilities.
