The only way would be the battery doing it, as it is the only thing capable of the required current. I just do not see how the load can happen in our dongle and then dissipater.

The COTS part of the charger is WADUKS WA360 we have an adapter that verifies communication to the battery before letting the voltage connect.

Thanks. To be clear, there is no way the customer could plug this in backwards without physically modifying the cable. This modification would be very noticeable and it would not be able to be hidden. This has not happened with these. Late friday I did get some good high temperatures...

Yes that is the cable.

there are 20 and 30A fuses, but fuses usually are spec'd at blowing at 250% rating after by 1 min.

Yes this is the question! My charger is limited to 10A, and I have tested ~20 of them. My battery can do more current, but thinking of a mechanism for this to be causing this issue. That is why I am asking to try to knock loose some data points and know approximately what current would cause...

My wire is 16 AWG (264 cores of 40 AWG) with 0.010 FEP Insulation. I have the insulation and the MJF nylon that it is touching melting! How much current would I need to have to get to these temperatures with this wire? This wire is inclosed inside the MJF nylon case, so figure for no air flow.
