Howdy Folks!
Loving the car so far, I mean, it's early into my ownership, but is has radically changed my perspective on vehicles.
So quick backstory, we scored a Wrangler 4xe, and wanted a L2 charger, shuffled through a few, but wound up - in expectation of a adding a Tesla to the garage - with a 40a Grizzl-E Smart (though not using any smart features at the moment). Great product, solid chassis, super heavy duty cables, 3 year warranty right out of the box, ~$479.
We got a new circuit installed, a 50a, with a short run to an N6-50 receptacle flush mounted, supposedly very reliable electrical contractor in town.
So it had been charging the Jeep at its max, 30a, works great, almost no issues, stays cool.
We added the M3P, and using the K1772 adapter, it fired right up, and charged the Tesla. However, at some point, like the 2nd time, I opened the Tesla app to check out the charging info, and it showed 32a/32a (around 237-238 volts). So it's like it's setting the max charge to 32a, vs. 40a. I tried it a few times, always the same, even confirmed the charging rate settings on the display.
Then I tried it a couple of times with the charging screen open, and I can see it actually starts at 40a, 0V, and 1-2 seconds later, switches down to 32a. FWIW, we have 250a service, and I've done this without anything else really running, just a few lights, maybe a TV or two (no washer/dryer, maybe AC[?]).
From a few posts here it sounds like maybe it might be a marginal install, and it's causing the Tesla to step down to the next level (as sort of a safety protocol). I have the same company sending over a service person on Friday, I guess they'll try a load test, maybe double check the grounding.
Anything else that could be passed on to them that might help with diagnosis?
I mean, I'm seeing 29 miles / hour, which is pretty solid, but I think I'm leaving another 8 miles/hour or so on the table by not utilizing the full 40a - plus, I have a small concern the lack of 40a may be indicative of an install that might have future issues.
Here's the setup, not really much to see, but I had a pic i posted at the Jeep forum handy
