I think the charge rates show
I think the charge rates show a lack of understanding of the low costs of running EV's generally. Property owners mots likely have never owned or even seen an EV when planning the installation at a property. If you ask a gasoline driver is $2.50 a reasonable cost for fuel they will say it's a bargain and call any EV owner a cheep skate when he points out the charge is too high.
EV' owners, unless desperate for a charge, will simply pass up the EVSE's that charge these rates. I imagine property managers will be both disappointed and bemused at the lack of use their equipment will get.
For a large mall, offering free charges will attract business. Charging a fee will not.
The only EVSE's that should attract a fee are Level 3 chargers.
