With the steady increase in the number of electric vehicles in Quebec, condominiums, multi-unit residential buildings and residential complexes must adapt to residents' new expectations. However, installing several charging stations often represents a challenge because of the electrical capacity limits of existing buildings.
It is in this context that the Energy Management System for Electric Vehicles (SGÉVÉ) becomes an essential tool. This technology makes it possible to optimize the use of available electricity, reduce infrastructure costs and facilitate the deployment of charging stations in multi-unit residential buildings.
Adding charging stations to a collective residential building raises several technical and financial issues.
Most existing buildings were not designed to power several electric vehicles simultaneously.
Without an energy management solution, adding charging stations may require:
These investments can quickly drive up project costs.
In buildings that use a shared electricity meter, it can be difficult to determine each user's consumption precisely.
Administrators must then find a fair and transparent method for allocating costs.
Integrating charging stations often requires physical adaptations to parking spaces, particularly in buildings that have already been constructed.
Without an intelligent system, the simultaneous charging of several vehicles can create significant consumption peaks and lead to higher electricity costs.
An Energy Management System for Electric Vehicles (SGÉVÉ) is an intelligent platform that controls and optimizes the distribution of electricity between several charging stations.
Its role is to automatically allocate the available power in order to prevent overloads and maximize the use of the existing infrastructure.
The system:
This approach makes it possible to install more charging stations without increasing the building's electrical capacity.
One of the main advantages of the SGÉVÉ is its ability to efficiently use the power already available in the building.
The system uses the unused capacity of the main panel to power the charging stations without affecting the building's other equipment.
The SGÉVÉ continuously measures:
This monitoring allows instant adjustments when electrical demand varies.
Using the OCPP protocol (Open Charge Point Protocol), the system communicates with the charging stations in order to:
The SGÉVÉ often makes it possible to add several charging stations without having to modify the building's electrical service entrance.
This approach significantly reduces deployment costs.
By avoiding major work such as:
owners can save tens of thousands of dollars.
Centralized charging management can make it possible to take advantage of more beneficial rate structures offered by Hydro-Québec.
For example:
Each charging station acts as an individual meter.
The system can:
The SGÉVÉ is designed to evolve.
It becomes possible to gradually add new charging stations without having to rethink the entire electrical installation.
The SGÉVÉ acts as a true charging control centre.
The charging stations are connected to the SGÉVÉ via:
Wireless communication between the charging stations and the management platform.
The OCPP protocol allows charging stations from different brands to communicate with the management system in a standardized way.
This compatibility provides greater flexibility when choosing equipment.
When several vehicles are plugged in simultaneously, the system:
When the building's general consumption decreases:
Most modern platforms include a web portal or mobile application.
Managers can view:
The system makes it possible to:
Platforms can automatically generate:

For condominiums and multi-unit residential buildings, the SGÉVÉ is often the key that makes the project technically and financially viable.
Faced with the rapid increase in the number of electric vehicles, multi-unit residential buildings must find effective solutions to offer charging to their residents. The Energy Management System for Electric Vehicles (SGÉVÉ) makes it possible to meet this challenge by optimizing existing electrical capacity, reducing infrastructure costs and simplifying the day-to-day management of charging stations.
Thanks to its expertise in transportation electrification, energy management and charging station installation, Bornes Québec supports condominiums, property managers and developers in designing scalable, high-performance projects adapted to tomorrow's needs.
