Below is a brief summary of a number of options to source power for EV charging. This is not intended to provide a complete list, but rather provide ideas that a strata can work through and develop their own solution.
Keep in mind that a building strategy will often involve more than one charging option depending on the individual apartment, car bays, proximity to infrastructure etc.
Standard Power Point
Apartments and multi-dwelling buildings
Charging from a standard power point in apartments and multi-dwelling buildings will likely increase overall power consumption and in this circumstance should not be considered.
Townhouse or single dwellings
If you are in a townhouse or single dwelling, then charging via an existing power point may be possible. Advice from an electrician should be sought to ensure the circuit has sufficient capacity.
Power Sourced from Apartment or Owner's Meter
It may be practical to run power cable from either the owner's meter or the apartment switchboard. In both of these cases, consumption will be billed to the owner.
If necessary, a load monitoring device can be installed which enables the EV charging circuit ONLY when the apartment has spare capacity. This ensures the apartment can not exceed design limits.
Power Outlet from Air Conditioner
Some apartments have their external air-conditioner units located in the basement, not far from the owner's parking bay. In this instance, a device may be installed that redirects the AC power circuit to an EV charger, but only when the AC is not in use. Because the power circuit can only run either the air conditioner or the charger (and never both), there is no additional power load on the apartment or building.
Load Managed System
A load management systems enables chargers to be installed without a negative impact on the general electricity supply by maintaining the overall load with the design parameters for the supply. See Load Managed Charging for more detail.
