Powering an electric vehicle charging infrastructure in a multi-unit building where the electric meters are located in the garage basement (accessible).
A capacity study was carried out by engineering firm CDI Groupe Conseil to assess the building’s residual energy capacity. The results of the report showed that there was insufficient capacity to connect all 43 32A chargers simultaneously.
The DCC charge controller solution was chosen, and the chargers installed were all limited to 20A to allow all residents to plug in their electric vehicles simultaneously, thus protecting the building’s electrical input.
DCCs were installed for all units in the building:
- DCC-9 for units with an electrical panel of 125A or less
- DCC-11 for units with a 200A electrical panel
