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.
