Visited on Friday without charging.
The chargers are in parking Nord. There are no EV signs at the shopping center entrance where the lanes split into the various parkings, but there's a sign above the north entrance when it branches out. Better be on the left lane already at that point.
There are no gates and I didn't find any mention of price or parking closing time. There's a mention about a car scanner above the entrance, but I don't know what it would enforce since it doesn't seem like there's any payment or time limit.
For the closing time, since the only exit is through the store it probably closes at the same time. That's what the opening hours in M-CHARGE app also suggests.
The chargers are in the first row directly forwards after the entrance.
We see marks on the wall where the free mway chargers presumably were. I don't remember if I've ever seen any picture of the old setup.
