Our block of 21 units has an individual lighting circuit to each parking bay, which is connected to a separate 20A breaker for each unit on the sub-boards. Initially there was just a switch for the lights, but some units have had power points installed.
Absolutely ideal situation to be in!
Lights in each parking bay would take almost nothing. A 15A socket would allow charging with the 10Amp portable EVSE charge cord that is supplied with most electric cars or can be purchased for a few hundred dollars. 15A charging, 50% faster, with a socket and 15A portable charge cord or a hard-wired unit set to a 15A limit is possible and they also don’t cost much. By limiting charging to 15A max. the building is unlikely to experience over-load problems and there might be that much new spare capacity anyway if people have replaced resistance heaters with heat pumps and got other more efficient electric devices.
Residents could be informed about options for time of use or other tariff structures that would provide a financial incentive to avoid charging on the evening peak.
The Owners Corporation has no administrative burden billing for charging from the common property supply.
Residents can proceed to getting an EV when it suits them rather than some being held back while others are not yet ready.
Perhaps all that is needed is a resolution to approve charging at up to 15A from each unit’s individual supply with the addition of a 15A socket or a wall-mounted EVSE outlet limited to 15A in each unit’s parking space with all repair and maintenance the responsibility of the relevant unit owner.
