In multifamily buildings, an EVEMS (electric vehicle energy management system) can monitor multiple levels of the electrical infrastructure to ensure safety and optimize charging:
- Building infrastructure: This includes monitoring the building’s main electrical service, transformers, and distribution panels. The goal is to ensure that the integration of charging stations does not exceed the electrical capacity of this equipment.
- Unit infrastructure: If charging stations are individually powered (from the unit), the EVEMS can monitor each unit’s power consumption to prevent individual electrical panels from overloading.
- Shared charging infrastructure: If the building has dedicated charging infrastructure (e.g., a shared panel for charging stations), the system monitors the consumption of this set of equipment to ensure that it operates within safe limits.
The results of the energy capacity study are crucial in determining precisely which levels of infrastructure require monitoring by the EVEMS.In short, effective monitoring ensures that charging stations are integrated safely and optimally, taking into account the building’s actual capacity.
For monitoring to be fully effective, the information collected must be analyzed and lead to concrete actions. The next article will explore in detail how data analysis, performed locally or remotely, ensures the security and optimization of your charging infrastructure.
