Everyone wanting to use the chargers pays the $15/month plus the usage charge. Our usage charge is $0.93 per hour of charging at 220v, 30 amps. I'm not sure how that translates to a per kWh cost, but generally my X takes about 9 hours to charge overnight from 20% to 90% at a cost of $8 to $9 per charge. Right now, there's only four subscribers to our chargers and, as more are added, the monthly $15 fee to EverCharge will increase. When it gets to the point that we need more than the two chargers, I believe the HOA will have to fund the installation costs, but EverCharge will provide the additional chargers at no additional cost (other than the monthly $15 fee). It seems this monthly fee arrangement may become quite lucrative for EverCharge!
