A useful thing for an Owners Corporation to have is a staged EV charging plan. For the first few early adopters, it would not cause any problem to do something formalised but simple and temporary such as allowing the use of ordinary common property power points with conditions attached. Those conditions could include a simple kWh counter in line so that the EV driver can reimburse the OC for the costs or a reasonable estimate of costs based on milage.
Another condition would be recognition that such arrangements are temporary until EV numbers are higher and a more sophisticated arrangement may be needed. More sophisticated arrangements could include a building load management system to share the available supply capacity among networked charging outlets by slowing down or stopping charging during the evening peak and speeding up charging as the demand from the rest of the building is reduced during the day and night.
