Infrastructure Upgrades for Inaccessible Meters for EV Charging in High Rise Homes
00:07 – In a setting where the meters for some units are inaccessible from the parking spaces, you will find the main switch and the main housing in the electrical room. These supply power to a transformer, to which the meters for the other units are connected. The same main housing also supplies power to the common areas meter, to which the transformer and the electrical panel for the common areas are connected.
00:34 – Before choosing the solution that will supply power to the charging stations, an energy capacity study must be carried out by an engineering firm in order to determine the unused capacity of the various electrical components which supply power to the building.
00:50 – Once the available electrical capacity is known, it then becomes possible to determine which power source can be used and whether new components will need to be added to the main electrical infrastructure in order to supply power to the charging stations.
01:06 – Power Supply Options
Power Supply From the Metering Centre
01:14 – When the unused electrical capacity of the main switch, main housing and transformer of a metering centre is sufficient, a second meter can be added for the units whose main meter is inaccessible. With these new meters, which will exclusively serve to recharge electric vehicles, it is then possible to run a cable to the desired parking space and supply power to the charging station
01:41 – Adding a column allows for the installation of six additional electricity meters. The total number of meters that can be added depends on two factors: the unused capacity of the electrical infrastructure and the physical space available.
01:57 – Please note that this solution is only permitted by certain electric utility distributors, and only when the main electricity meter of a unit is not accessible from the parking spaces.
