How paid commerical places work, you pay on the charging device with either your phone or credit/debit card. Tesla Super Chargers are done via the Telsa app.
My condo you need to let security know you want to charge so they know which unit to bill. Until they input that, no flow of juice starts.
How I see the most effective way if they do charge, then go with the credit card machine on the unit, like how you do for gas.No condo will install chargers at every stall. This would cost way too much. Instead a section of the garage with like 5-10 charging stations. But now this will cut into the developers profit because these are 10 less parking stalls they can sell for new buildings.
You can actually charge an EV with a standard 110-120V outlet.
it's much slower than using a car charger, and commercially it avoids being able to allocate that amount of electricity to someone who needs to pay for their charging time. So, the condo is going to have to lock down ALL their accessible outlets to prevent "energy theft" unless they are okay with everyone subsidizing "Green Energy" for those who opt-in.
Since electricity isn't free, and in a condo environment everyone shares the cost of common area electricity usage, it's going to take some degree of investment and monitoring to make sure the people benefitting are the only one's paying.
Energy is a funny thing. There's always a trade-off. If you go with this type vs. others, it might be what's most effective, but it also costs the most. Going another route means it's cleaner and less harmful to the planet (theoretically), but it's less convenient, less effective, has limitations, and is not readily available wherever you need it. And on and on it goes.
Maybe the condo associations need to write Biden and request subsidies for these Green Energy vampires that suck more than their fair share of electricity while not paying the per-gallon-of-gas state and federal taxes they used to?
