I'm inclined to think it is an EVSE issue and not an Leaf issue.
1 - That EVSE had just previously reported a ground fault error message.
2 - What can the car realistically do back to the EVSE that it wouldn't be designed to handle and would be able to do so if it was working properly? The fact that unit died and smoked means the issue is in that unit. The car's systems likely just got in the way of a nasty spike from an improperly grounded and malfunctioning EVSE.
Of course, I'm not an engineer. Any of you have counter points on the above logic?
Of past issues with the Leaf and AV units, etc., were those issues of the car not charging from them? Or were those issues of the unit dying and killing the car too? I would think the former as that could reasonably easily be fixed with a Leaf firmware update. But the later would be more of an EVSE issue. So I think this must be different than that issue.
The thread is about a CHAdeMO unit, which means this is not an EVSE, but rather we are talking about a charger. IMO, the potential for damage is much higher with a charger since the power levels of the sources on both sides of the connection are so much higher. As such, any violation of the handshaking which occurs with CHAdeMO can be catastrophic. With an EVSE, typically it is only the on-board charger and the AC wiring to it which are at risk.
