Visited on Monday without charging.
The chargers are in the perimeter of the DMV. There's no branding for a CPO, except for the Partino QR codes.
The signs through the parking say you can only park here on business with the DMV. But this probably pre-dates the charging stations and the chargers don't have any signage of their own.
The parking spots have numbers, but I did not find any parking meter. Parking seems to be free. Maybe the numbers are there so you can say where you car is to the personal.
There is no gate, so it's probably possible to charge around the clock.
