How to prepare a building for electric vehicle charging: a document prepared by RVE
In Multi-Unit Residential Buildings (MURBs) and townhouses, the DCC solution allows for the supply of an Electric Vehicle Supply Equipment (EVSE) from the dwelling’s panelboard based on relaxations allowed by Rule 8-106(10) or 8-106(11) of the Canadian Electrical Code, Part I (CE Code) private electrical infrastructure. The DCC, which is an Electric Vehicle Management System (EVEMS) single-tier, monitors the current in the feeder supplying the panel of a dwelling and temporarily disconnects the connected charger when the current intensity reaches a pre-set threshold.
In the general context of installation, without use of the EVEMS under conditions listed in Rule 8-106(10) or (11), the CE Code Canadian electrical code currently requires that the EVSE load must be calculated with the demand factor of 100%.
In order to ensure that the distribution upstream of the dwelling panel feeder is not overloaded, it is necessery to:
Conduct an energy capacity study to determine how many EVSE can be installed before further action is required;
If the maximum amount of EVSE have been installed, put in place a long term strategy.
