Quick Charging fails - DTC code - B2820 0028

[Evoforce]

I in fact have a Harbor Freight 12 volt load tester and it has worked for years testing hundreds of times. Sometimes they are on sale or have 20% off coupons in their circulars. I don't have a clue about the bad reviews. Maybe they had a bad batch. Mine has worked flawlessly. It is a resistive coil in a metal box with a built in gauge and a toggle switch to apply the load through the resistive wire. Similar to turning on a toaster which runs current through wire coils to heat your toast.

The tools that I previously mentioned are still good to have on hand in any case. AutoZone or O'Reilly can tell you if your battery is good and is performing as to it's rating. Others that I know, say that the warranty is not as good on the Dealers battery as a replacement from AutoZone. You more than likely have a 3ish year old battery. Did you put it on the charger to top it off to see it's readings? Attach your 12 volt, charger with black lead to good metal ground (not battery) red to battery positive, check your settings, then plug it in to the wall. When done, unplug from the wall first then remove charge leads.

I couldn't find my other meter to test it and since the battery was at least 4 years old and reading 11v on my limited tester, I got a replacement. $98 from my Nissan dealership. I cleared the codes, using Leaf Spy Pro, like I used to do each time before testing the QC and all the DTC would return. This time they have all gone and I've been using QC down the street on three different days for the past week and I've not any the DTC come back. Either I'm on a good luck run and those codes, including something about brakes, are just waiting to pop back up again at any moment or the original responder was right, they were all related to my accessory battery.

I update this post if i get the DTC codes back and QC charging complains about "car must be turned off: when it was off.

I am getting error code on a quick charge station; "cannot charge car, needs to be powered off

However, If I move the Leaf to the next quick charge station, it works fine, every time.

Other EV's seem to have the same issue on the same charging station, but not all.

The station owners refuse to send someone out, because the station works for 'some' cars, so they blame my 2016 Nissan Leaf.

Why would the problem be the car, when I can move over to the next station 10 feet away, and that one always works fine?

I think you've nailed it, the cars do testing on the line for ground and pilot things, stuff I don't understand. but if more than 1 car fails on it, it's not your car. you're follow the scientific method here and found that the owner is not. UNless each of the cars have a weak, 12v batteries, I don't know what you can say. the true is that this station is the issue, or the wiring to that station.
