Electric vehicles in multi-unit buildings: calculating how many can be plugged in

To determine whether a building has the available capacity to supply all the charging stations required for the electrification of parking spaces, a load calculation must be carried out on the building’s existing electrical infrastructure.

This load calculation is therefore the first step in designing a charging strategy for a multi-unit building.

There are different methods available to carry out this load calculation: one method uses nominal data (section 8 of the Quebec Electrical Code), the other uses measured data (art. 8-106 8 of the Quebec Electrical Code). Read the article published in the Corporation des maîtres électriciens du Québec (CMEQ) E2Q magazine to understand these different methods and how to apply them.
