[Oeva-list] Siemens EVSE

Is there precedent for EVSE’s frying the pilot signal diode?  Assuming so, how rare and which make of cars & EVSE’s were involved?

I can see this being the Achilles heel of J1772 if EVSE designs can over-current or over-voltage a diode that is so embedded on-board that the charging unit has to be replaced.

Have him test it on a Blink to make sure the Siemens didn't fry the pilot signal diode on the Leaf. If the Blink won't charge it the internal charger will need to be replaced.

One of my coworkers got a great lease deal on a Leaf a few months ago. He bought a Siemens EVSE from a local home store and installed it himself and everything was working great. 


As so many people do, they fell in love with EVs. So they traded in their other car for a Volt. Now they are a two plug-in car family. 


Then this week, the Leaf stopped working with the Siemens charger. The Volt works with the Siemens and the Leaf works with its trickle. It is just the combination of the Siemens and the Leaf that fails.


Have any of you seen anything like this? 


I suggested that he contact Nissan right away.
