Visited on Monday without charging.
The chargers are in the outside parking lot. There's a 90 minutes parking limit enforced by camera. There's no gate, so the chargers can probably be used outside of opening hours as well.
There's still the push button on the charger like at other Aldi, but the stickers don't mention the free charging time, so I guess this was discontinued. I'll need to test the button at an Aldi one of these days to see whether anything happens.
I was not able to take a good picture from the entrance because people kept parking in the no-parking area right in front of the entrance, blocking my view of the chargers.
This area isn't very pedestrian friendly. If you parked at the Migros and walk to Aldi like I did, there's a good chance you get run over. It's only 2 blocks away but the footpath changes side 2 times and there's a 4-way intersection where everyone exiting Migros has to drive through.
