The Intellimeter EVCMC is an EV Energy Management System built for Multi-Unit-Dwellings, Condos, Apartment Buildings, or Strata, that saves Home-Owner-Associations, expensive and lengthy utility service upgrades, by using the existing electrical capacity in the building, for EV Charging and maximizing in the most efficient way the energy distribution to ensure that every EV receives enough charge for the daily commute.

Intellimeter has developed the i-meter® EVCMC which is a demand controller for multiple Level II EV chargers. It is meant to share the car charging loads and expand the charging capabilities within the existing building constraints. The i-meter® EVCMC protects the existing infrastructure from overloads, and avoids excessive demand charges. Our EVCMC manages the existing capacity in the building, therefore, avoiding the unnecessary costly upgrade of the buildings' existing electrical infrastructure. It can also save a lot of money in the deployment of EV chargers in new construction by reducing the size of the main feeder. The EVCMC can be used with any charger and ensures that the existing capacity is never exceeded, protecting the building and maximizing the capacity among the EV's being charged.

Ultimately, the i-meter EVCMC allows building owners to triple the number of EV chargers they’d otherwise be able to deploy, without reworking the buildings' existing electrical infrastructure. The EVCMC combines a three phase 120/208VAC distribution panel board with multiple two-pole 40A breakers as required, one or two i-meter®45, individual contactors for each charger circuit and a controller that is programmable to manage the power and the time allocated for each charger.

Because of Intellimeter's experience in sub-metering, naturally, we provide a revenue grade, Measurement Canada and California approved and sealed meter which can be used for legal billing purposes for every charger. Intellimeter’s i-meter-45 metering module is at the core of the EVCMC. This is required in order to address the energy cost recovery from the common elements and to monitor the current draw of each of the charging circuits. As a redundancy mechanism, the EVCMC also monitors the mains of the feeder set aside for these chargers.

The i-meter EVCMC ensures the protection of the existing infrastructure, by alternating and distributing the power of multiple chargers. As a car is plugged into the charger and begins its charge, the i-meter® EVCMC tracks how much time the charger has been on. As more cars are plugged in, the i-meter® EVCMC monitors the total charge to ensure that the contracted demand or ampacity of the breaker is never exceeded. It does this by disconnecting the car chargers gradually, based on the amount of time they have been on, protecting the existing infrastructure and allowing the alternation and distribution of the power to multiple chargers. As the load diminishes, the car chargers are automatically connected again.
