That is unnecessary. In NSW this would not work, because of the Cooper case, which makes a by-law that bans behavior that MIGHT create a problem invalid, and only permit restrictions in by-laws that actually are shown with evidence to create problems.
As a secretary of a NSW strata committee, and an electric car owner for the last 6 months, I can confirm that Type 1 charging is very satisfactory – namely installing a regular 3-pin socket in my parking bay on a circuit that runs through my Unit’s electricity meter. Electric cars can operate well with building power capacity limits, because the cars all (newer ones anyway) come with a function to re-charge on a time schedule. So a building with power capacity problems could have a by-law that electric cars may only be recharged using Type 1 recharging equipment, during off-peak hours – eg 8pm to 6am, for example, when little of the building’s power is being used.
Buildings hoping to avoid upgrading their power supply equipment are going to be disappointed – the government already has mandated that all electricity meters are to be changed to smart-type meters. This will involve replacing the old analogue meters with smart meters, adding a meter circuit-breaker, and often also replacing old non-compliant electricity switch-boards (eg, these can contain asbestos). Smart meters allow time-of-day rates, which make charging electric cars during off-peak times very sensible (at about half the cost of charging the car at the single rate).
But the charging circuits for cars should be put through the owner’s meter, and not using the common property power supply. Although there are solutions, like “ReadySteadyPlug” that allow common power circuits to be used, with users being individually billed for the power they consume. It is also possible to handle the use of common property power more simply, with a by-law that permits powering electric cars from the common power supply, upon application, with the owners submitting the power used readings from their cars, quarterly, and the OC on-charging a reasonable cost. But adding new circuits for owners sockets in the garage area will sometimes run into the same issue as above, with smart-meters, requiring the building to upgrade its switchboard (not to mention old switchboards often contain asbestos, so any work on it will require it to be replaced).
