Visited on Sunday without charging.
There's no gate closing the parking on Sunday, and I didn't see any sign forbidding parking outside business hours. The parking meter lists paid hours, and Sunday is not included, so I guess it's allowed and free? This means the DC chargers are accessible 24/7. Someone was actually charging.
I have not noticed during my last visit, but it looks like the newer charger on the left might have the contactless reader integrated into the screen, as there are 3 lights for the reader animation. But there was no standby blue light so I doubt it's activated. I didn't try plugging in, I'll try again another time.
