I cannot get my MME to charge using the Porsche Mobile Charger that is used to charge the Porsche Taycan. I keep getting a Charge Station Fault message — am I doing something wrong? Are these chargers incompatible? Hoping im missing something silly. I am just turning the car off, and plugging the car in. The light on the port is blue for a few seconds before throwing the error and flashing orange. On the charge station it just says “Charge Connection Established.”

Does the Ford Mobile Charger work ok on this Mache E?

If the Porsche charger has a J-1772 connector, it should work on any electric vehicle for L2 charging.

If the Ford Mobile Charger works, and the Porsche Mobile Charger doesn't work, then...

I have not tried it yet, I typically charge at the Chargepoint charger in my building.

Ok just confirmed that the Ford charger works. Strange that the Porsche one doesn’t. Will do some more research and report back.

So I got it to charge by decreasing the charge power on the Porsche charger to 20A. Going to try to tune it up and see how high I can go. It failed at 40A and 32A but succeeded at 20A. Will report back.

MME can accept a max of 32a, so there must be an issue with internal communication setting the limit..... MME doesn't speak German ?! ;)

It ended up maybe having nothing to do with the amperage, it just seems to work 20% of the time intermittently. I gave up on it and am just setting up the Ford Charger when I charge there.
