"Here's the bad pin in the blink handle":

Image

I'm certified to inspect this type of crimp at Boeing 777 QA production. It is reject-able on many levels. The conductor strand insertion is obvious and serious. The sharp edge on the lower side is called flashing. A small sharp edge is ok, but this is way to much, caused by over crimping or mis-placement in the tool. The crimp position on the the crimp barrel measured from the end is good. But the all important inspection hole on the crimp barrel is absent. When I see the excessive stripping of the insulation, and no inspection hole to witness full insertion of the conductor, I suspect the conductor slid out while crimping. Only a cut-a-way cross section would answer that.

But the O-ring is a nice touch ;)

Interesting as I saw a blink was in the process of heating the plastic on the same pin today. I charged it for 3.5 hrs to come out and see (just a little) of plastic melted on the Blink. It is the same exact pin. I used that same charger in the morning for 2 hours but did not see the problem.

This 2nd Blink EVSE with similar problem now.

Yikes! Make sure to call Blink ASAP.

I'm finally testing charging w/ the Blink instead of the CT-500 as I'm contemplating car positions in the garage.

After about 45 minutes I measured around 130F with my infrared (pointing in the different spots of the nozzle.

I tried searching the relevant posts but search is failing me.

Thanks.

What's the ambient temp? It seems too hot. Measure your Chargepoint for a comparison.

Ambient was in the mid 70s. I will have to test again.

On my replaced Blink cord, the J1772 plug was still cool after 90 minutes charging the RAV4. The cable was warm, maybe 110f.

I retested. The outside was warm around 105F. The IR thermometer was reading highs of around 150F in the plug part (after I stopped charging and unplugged). Inserted a thermocouple in one of the EVSE plug and it also read over 150F.

That sounds a bit too hot to me. Be careful, and read this thread before you use that Blink j1772 nozzle again:

Also search for "blink melted"

I finally got around to calling Blink and they agreed that 150F was too warm and they're ordered a new cord set and will arrange a time do a swap. Their threshold appears to about 50C.
