I see a lot of PiPs on campus at work. They usually insist on charging from a row of 6.6 kW Eaton stations, but are typically good about moving their vehicles. Take today for example, there were three Leafs and an ActiveE charging from 120V outlets. Meanwhile, several PiPs and Volts were gracing the Eaton row :roll:Image

I'm glad to hear that Toyota is flying out an engineer to look at the Rav. This could very well be on them and Tesla. Tony is a power user, literally. But what would the average consumer do? These things should be robust, and require no brain power to use. Plugin, charge, drive, repeat.

Anecdotal info FWIW:
I did one charge on a RAV4 from my garage Blink. Extended range mode from about 1/3 of a "tank".
The handle got noticeably warm and yes the RAV4 charge inlet is much higher than my LEAF which puts more cable weight
on the connector and attachment. It wasn't so warm that I was concerned and I've since inspected my Blink pins and all looks normal. But, thanks for the heads-up (and gory pics) Tony, it's something for us to keep an eye on when we have Teslas, RAV4s and LEAFs in our garages.

melted pins is sign of a major failure in design. Quality of the components might be suspect, but good design can override that. seems to me a fuse, circuit breaker or something on either the car, the EVSE or both should have done something before the option to charge the car is destroyed.

IMM, the car should be able to accept a fairly liberal tolerance of plugs and fits. they might all be J-1772 but different manufacturers, different materials, tolerances, etc. the car should be able to handle all that.

this reminds me of a GM a co-worker had. 3 times, it died on him in the middle of rush hour traffic on the Tacoma Narrows Bridge. this was in 96-97 before the other span was put up. One cant even begin to understand the disruption of traffic in an area where its very difficult to get emergency vehicles on the bridge.

but basically what was happening is a $2000 computer was being damaged by various causes (no real determination was ever found) He eventually lemon-lawed the van after about 18 months. I happen to run into him one day about 5 years ago and he stated that there was a recall a few years after that that required installation of a $15 fusible link which ran to the same computer.

no way to know if both were related but he was pretty convinced

Interesting that the picture looks like the female contacts remained stuck on the car's male pins when the handle was pulled out.
I noticed you're still working with polymers.

Toyota has none in stock, and it's from Tesla. So, they are trying to get one from Fremont.

Aha, the plot thickens. It's possible that it's a Delphi inlet then, and not Yazaki. Especially, if it came from Tesla. Hope you can get it replaced soon.

Sorry! Speaking of which, does this look vaguely familiar (ignore the wiring for the moment):

Yes, I believe that's how a cord set with an inlet would look like. Think "J1772 extension cord".
