You should speak to your condo association and get an estimate for an electrical car charging infrastructure in your parking garage. Current Electrical Contractors had done 3 such installations in the last two years. We partner with Evercharge evercharge.net They sell a product that allows many vehicles to be charging at the same time. There needs to be an installation of the infrastructure for these to be plugged in to. We specialize in the infrastructure for Evercharge. We then run power from the electrical panels that we install on each level of the parking garage to the Evercharge smart EV chargers. The customer can swipe a credit card and pays only for the electricity being used from that unit. Evercharge pays the electrical bill for the meter that feeds the infrastructure. These EV chargers are all linked together wirelessly. The engineers at Evercharge set them up so that up to a certain capacity of the main breaker feeding the panel on that floor everyone gets 100% charge. When too many people are plugged in the charge to each vehicle is reduced by the same amount so that everyone gets a charge just not at 100%.
