It is amazing how poorly designed they are and how many blatant errors they made! It is not a charger that you will ever be able to rely on always being functional... (Heck, not even being functional a majority of the time!) Nissan should be ashamed!


I would take a guess that the Nissan brand chargers main goal when it was designed was to be as cheap as possible to sell as many dealers as possible on the idea of putting in a quick charger.

Am I defending it or saying that it is not crap? No, but they probably had a good clue what they were doing and made it as cheap as possible to land the Nissan contract and get as many out there as they could.

What Nissan should be ashamed of is not making sure it gets updated. The simple answer would be a temp sensor that puts it in a reduced power mode, the better answer would be an revised cooling system. However from previous comments we can see the only owners who care are for those with units that make money!

Out of my own curiosity does anyone now how long the charger is out for if it has the temp error? Does it need to be serviced, reset or simply cool down?

If the unit trips on temp error it needs to have the filter(s) cleaned.
There are some fairly easy to service primary filters and some internal filters that require special trained technician for service.
Should NOT be used any more until they are cleaned.

But unfortunately that did not happen at many dealers.

Unit would cool down and start working. Not sure how long cool down took as it never happened while charging my LEAF.

But with multiple thermal cycles the components eventually fail.
So in Chattanooga the $12,000 unit (which Nissan bought) needs a $5,000 repair.
Dealer won't pay and so far dealer hasn't gotten Nissan to do anything.

A lot of the Chattanooga unit tripping was when used by a Tesla.
The unit is 44 kW and with LEAF use rarely operated at 44 kW for more than five minutes.
But with Tesla would sit at 44 kW for a long time and often trip on temperature.

Now it is dead and all we have in Chattanooga is L2.
All of the DCQC are broken and the only one that might be repaired is the one at Sears.

The CHadeMo DC fast charger at the Nissan Dealership in O'Fallon, IL has been down, do to it overheating, every time have been there. The loyalty manager told us that it was a very common problem with Chademo DC chargers. I'm relieved to see that this is a common problem, because I thought that sounded fishy. But I'm also quite surprised, & annoyed, to learn that Nissan hasn't managed to take care of the problem if it is that common.

The loyalty manager should look into cleaning or replacing the unit's air filters. It's unreal how auto dealerships can't conceive that these things might have maintenance requirements.
I noticed you're still working with polymers.
