Hi Chuck,
Are you talking about level 1 or level 2 chargers at every parking spot?

Yes, I can’t imagine anyone would design a service that expects people to get 
up in the middle of the night to move their cars. That’s certainly not our 
design. We took into account that “overnight” would represent one block of 
charging time (whether you define “overnight" as 6PM - 6AM, 9PM - 9AM, 8PM - 
7AM, or variations on that theme). 

Cheers
Philip
