Case Study
Le Laurier
After designating the individual approach as the preferred way to install charging stations in its charging policy, the syndicate of co-owners of the Laurier commissioned an energy capacity study and then realized that a global approach was needed to enable all co-owners to have access to a charging station without overloading the transformers. In addition to enabling all residents to charge their electric vehicles (EVs) at home and protecting the electrical infrastructure, the RVE technologies installed at Laurier added value to the condos, reassured future EV buyers and avoided internal conflicts and the administrative burden required of the condo board. The installation was masterfully carried out by the FFC Électrique team.

Challenge
Powering an electric vehicle charging infrastructure in a multi-unit building where the electric meters are located in the garage basement (accessible), while protecting the existing electrical infrastructure.
Solution
Using a homogenous solution was possible to power charging infrastructure between all units of this condo building and the EV chargers that were requested to be installed. Indeed, all meters are accessible, allowing the use of DCCs everywhere.
DCCs have been installed for all units of the building:
- DCC-9-BOX and DCC-11-BOX to provide charging infrastructure without installing chargers right away
- DCC-9 for units with an electrical panel of 125A and less wanting a charger now
A HUB by RVE has also been installed in the electrical room:
- The HUB installed with the DCCs protects the electrical infrastructure by providing dynamic, intelligent energy management based on actual charging station consumption and the available electrical capacity of infrastructure components. The HUB makes it possible to anticipate energy needs and offer the essential service of full charging to 100% of residents.
- Without the installation of the HUB in this multi-unit residential building, the main service entrance would have had to be upgraded for a capacity of 1232 kW (equivalent to 160 charging stations at 7,7 kW each). The work would have cost over $500,000, according to FFC Électrique, the master electrician specializing in the installation of charging stations who carried out the work. By contrast, the HUB costs around $20,000 (installation included), representing a saving of $480,000.
« We had an energy capacity study made on our transformers and with the results, we realized that we had to coordinate everything relating to the installation of electric vehicle charging stations. […] By installing the HUB, we can monitor and control our transformers, control the DCCs, and each co-owner is guaranteed to have […] enough capacity for charging their EV without affecting the electricity allocated to their condo unit. »
