Thoughts?

Customer sent photo of a chargepoint they plugged into a 50 amp kiln receptacle we did a year ago, fed from a Homeline 50. Said they weren't sure what amps they set it to. Going to inspect the circuit Tuesday for them, as I've seen a polestar burn up a 60 amp ge and kill a chatger. I feel like the issues with car chargers will be frequent. Already had 2 clients get the red light of death on wall connectors. Interesting.

I'm not a fan of those clip connections, especially when high current is travelling. Seems like a loose connections that caused resistance/heat.

I guess I'd need to know what setting the charger was set to. The early Tesla chargers that went up to 80 amps smoked a couple of my installs. The newer ones have been ok. I don't care for the idea of the latest gen Tesla ones need you to connect to wifi to adjust the charger output. The previous ones had switching for it that I remember. What I really hate is skimpy to no documentation delivered with products and all you get is one of those codes to scan or a link. Don't they realize even in affluent areas, there isn't always wifi or cell service available. The lousy pictograms and poorly translated text is crap.

I agree but those pressure clips do seem to have alot of pressure behind them.

I usually see those in hot tub control panels. Not a fan, but haven't seen one of those burn (yet).

I have noticed the newer ones having more pressure, let us know what you find..that is if there's a visible story on the melt down...

Polarity seems correct, it could be that only a few strands were inserted and the rest bent back as the cable was being pushed in.

Do these plug into a receptacle already there? It looks like you can order a couple of versions 14-50 or 6-50. Internal wiring should be able to handle any amp setting. Manufacturing defect?

They may have set it for 48 even though it's plugged into a 50 amp kiln receptacle. They tried to get me to make them a second invoice a year after install, saying car receptacle not kiln receptacle like the original ironically enough. I told them it was against company policy.

Yes probably. Cheap junk.

Theyre like tinned or soldered ends on the wall plug cord and those come preterminated. The installer puts the car charging cable under pressure clips which are also tinned.

And this one was a 6-50r.

That's right, thanks for kicking around the electrons in my memory. I am now thinking it was the soldering point to the board perhaps..mfr defect

So it burned up in a place that’s factory installed?

It appears so yes. I will go check breaker, split bolts and receptacle connections Tuesday

Most of my experience has been with Tesla. I've wired Porsche and some other off brand someone else provided. I wouldn't know whose to buy if it wasn't Tesla. We have a Tesla and I haven't bothered to put in a wall charger yet because the 120v has been keeping up with my wifes driving. Shes been working from home mostly so the 120v is fine.

Update appears to be a factory issue. Checked everything and everything was tight and safe.

 

[nrp3]

Going with a replacement or different brand?

Been there done that, several customers called.."my Tesla car tells me the plug gets too hot and reduces amperage and then stops charging"

Interesting. I have one of these to check on sometime.

They already had a replacement chargepoint

Same and I have one to replace next week. This particular wall connector is just shy of 3 yrs old.
So so green
