I have a Tesla wall charger with adapter 80 amp how can I check to see what it is delivering?

Yep, I’ve got the one on the bottom of those diagrams.

Ive got a 80A charger and I use a Teslatap with it. I get 16-17kW when I use it as long as my 2nd linked 80A charger is free.

11kW amounts to roughly 48A...

Things I would check..

1) That I have an ER. You did say Er platinum but you also said you had to buy a Pro Charger, and I tho if it they came with all ERs..or yours could be used to. But felt it was important to point out as standard range charges slower.

I have a 2022 Platinum which is extended range bought used 8k miles so bought the Pro charger from ford

2) Check the panel. 80A charger should be on a 100A breaker. If you’re not, you’re not setup to deliver 80A despite having an 80A charger.

My tesla charger is installed on his own 100amp circuit and is set to 80 amps, My tesla Model X charges at 72amps no problem every day.

3) Check the wall charger. There’s settings to adjust the charging speed. Check to make sure the electrician actually enabled 80A vs another.

The charger is set at 80amps verified by my Model X charging at 72 amps (46miles/hr) no problem.

4) If there’s a 2nd linked charger, check to see if the one you’re using is setup as primary. Also try charging it with the 2nd charger free as connecting two cars at once will cause load sharing of 80A between two vehicles.

I dont have a second charger installed as of yet because my panel is out of space. I have the FOrd Charger Pro but is there a way to essentially put a switch between the two and just change where power diverts to so I use one or the other when installing rather than both together would much rather fast charging rather than 2 at same time.

5) Not a check but an awareness, keep in mind it depends on weather. The truck can take time to ramp sometimes, preventing full speeds until the battery is at an optimal temperature.

At 80A you should see 16-17kW. definitely not seeing that from 18% battery to 100% it took 8hrs 37 min the day before the other post above

If you’ve eliminated the charger than it’s your adapter or your truck.

Here’s some pictures of my equipment:

To note, I did not start off with a Teslatap. I started off with a Lectron which worked…but even at 48A tripped my charger heat sensor several times.

Here’s my app immediately upon plug in showing 3KW.

It ramped to 6KW within 30 seconds and -4KW within one minute - temps were favorable. It’s taken as much as 10 minutes to ramp before.

The truck paused to do an update before eventually hitting the 16KW I’ve been accustomed to seeing.

@Yellow Buddy you've got a V2 Wall Connector. We still don’t know what version the OP has because he hasn’t told us.

Yup I do, only the V1s and V2s were capable of 80A. So 50% shot…

I have a TeslaTap for my Mach-E. When I got the Lightning, I balked at the price for the Tesla Tap Lightning version, and bought a Stellar adapter from A2ZEV.

I tested it at a Tesla destination charger, and it worked fine for the 5 minutes I had it running. I have no experience with it at 80amps, but they have tested it and claim it works fine (I spoke to the owner).

Also, view Tesla Wall Connector power and temperatures by using the Android app Tewamo, or the Apple app Wall Monitor?

Tesla wall charger has a MAX compatibility of an 60A circuit breaker. That being said, that same charger will receive up to 60A, but the car will only see 48A as a max (80% of incoming amperage). Regardless if you have a 100A/80A breaker... your wall charger will only ever see 60A. I suspect this is dangerous as well, since your charger will never trip the 100A/80A circuit.

So I imagine the most you will ever get out of a Tesla wall charger is 48A to the vehicle.

P.S. - YES. I own a Tesla v3 wall charger and use the Lectron adapter running at 48A. I also charger our Tesla with this same wall charger, so I do have some experience with this.

When I clicked on it it said 11 kw/h. I dont understand why so slow, on an 80 amp charger, both charger and adapter are 80 amp. Does ford limit it because i have not installed the Pro charger , I was trying to avoid having major electrical with two chargers for both cars.

The onboard charger does not support 80amp charging. The ford charge station pro uses the ccs port, not just j1772. And no Tesla actually supports 80 amp charging as far as I know. Is your vehicle a standard range? Is that why you do not have the charge station pro?

Not entirely correct.
Tesla Gen 1/2 does 80A
Your circuit is 60A to handle a continuous load of 50A (heat etc.) not because that's how much you supply to the charger, the charger won't "recieve" 60A unless it's capable of/set to 60A, in which case a 60A circuit is too small.

The OP has a Lightning Platinum, which has an ER battery and 2 onboard AC to DC chargers, which can process up to 80 amps AC current through the J1772 connection.

The Lighting CCS-1 port DC pins are only used at home to EXPORT DC power from the trucks battery pack, through the FCSP to a Home Integration System [HIS], it does not channel any AC power into the truck.

Ok, didn’t know the CCS pins scenario. But this is right from Teslas website…

also here,

everything seems on the up and up. Lastly to anyone that does not know, in the wall connector software you also have to set the amperage of the circuit. But looks like it’s set correctly for 60 which is max.

No, I had the Ford Charge Pro wall charger (but already sold it). Not interested in chargers all over my garage, and since we already have a Tesla, and a Tesla wall charger, I just use the Lectron adapter... and don't mind the battery charging a little slower. Probably a healthier solution for the battery long term. Not a problem.

Snap on the adapter, charge the Lightning. Remove the adapter, cabled reaches over to the Tesla too. Easy.

 

[Shawnson]

It’s what I do. Works well for me too. But the poster was concerned about charging speeds. I have my ford charger still in the box but if I can figure out a way to get the Tesla charger to the opposite side at the front it will be handy for charging on the driveway so I might pull the ford out of the box one day.

You just keep doubling down huh?

You're quoting Tesla's website..but you're late to the Tesla party. By the time you got in, Tesla nerfed the chargers and the cars. As an OG Tesla owner, let me link you to the Gen 2 details here:
https://www.tesla.com/support/charging/gen-2-wall-connector

If you're still skeptical, feel free to refer to post #32 where I posted a picture of my 80A enabled Lightning using a 80A TeslaTap Adapter, on my 80A Gen2 load sharing Tesla Wall Connector.

Also...wireless/app capability only started on Gen3. Not available on the Gen1 and 2. We poor unfortunate souls had to open up the wall connector to manually set the dial. You can find the instructions here, as well as see that the "D" setting is for 80A output: https://www.tesla.com/sites/default...tor_installation_manual_80A_en_US.pdf#page=23

And since OP said he installed the wall connector in 2016, it would either be a Gen1 v2, or a Gen 2 wall connector. Both of which are 80A capable.
