RVE DCC-12 EV Energy Management System
May 14, 2026
The DCC-12 is a patented Electric Vehicle Energy Management System (EVEMS) that allows a charger to be connected directly to an electrical panel which would otherwise not have sufficient capacity to allow the connection.
Features
- Avoids upgrading an electrical panel that is at full capacity
- Direct billing according to the energy consumed (kWh) by electric vehicles
- No additional load on the home’s electrical panel
- Installation with electrical loads up to 100 A
- Circuit switching feature (load miser) allowing two loads to be installed on the same circuit breaker while preventing them from operating simultaneously
- Ideal for single-family homes
- NEMA-3R enclosure for indoor or outdoor installation
- CSA and UL listed
- No built-in circuit breaker acting as an intermediary between the charger and the DCC
- Made in Canada
How it Works
- Real-time reading of the total panel power consumption with pre-wired current transformers (CT);
- Detects when total power consumption exceeds 80% of main circuit breaker capacity and temporarily de-energizes the EV charger;
- Automatically re-energizes the EV charger when the total power consumption is less than 80% of main circuit breaker capacity for more than 15 minutes.
Installation Context
Install a DCC-12 so that you can connect an EV charger directly to the main power supply of the home and when
- This electrical panel has a maximum capacity of 200A;
- This electrical panel has already reached its maximum capacity;
For an installation in a multi-unit residential building, try the DCC-11.
