Some members will remember that I had issues with charging my EV3 which I collected in December. The car is currently in the garage and I have a courtesy car to give them a chance to resolve it. Having tried charging on other chargers away from home (both fast charge on DC and slower charges on 7 kw, 22kw using AC) I have been able to confirm to the garage that when fast charging there is no problem, but anything using the AC port causes issues. E.g. on a 22kw it was only charging at 3.4 kw, on a 42 kw AC only it was charging at 10.3 kw. I have saved all of the screenshots from the App and provided them. I am also now charging the replacement courtesy car on my home charger with no issues. Just wonder if anyone else has had this issue since I last posted? Thanks in advance

That looks okay, but sometimes for me it needed a continuous charge of a few hours to see the step down. As time went on the step down tended to occur sooner on average. Too soon to draw a conclusive opinion, I would suggest keep monitoring and recording what happens. I only involved the dealer after it became reasonably predictable and I had some screen shots to show them.

Re AC home charging.
I bought my EV3LR in May 2025.
I had 2 breakdown events which were eventually resolved as there was a 12v battery fault which was replaced.
Since day one I have had interruptions in the overnight home charging and failure to charge to the full 70%.
I use the current setting of 60% as interruptions are described with 90 and 100% current settings.
The dealership service department doesn’t Seem to have much understanding of the AC charging aspect so any comments are appreciated.
