DCC provides electricians with a simplified installation process for electric vehicle chargers where the electrical panel is at full capacity.
DCC units, or Demand Charge Controllers for electric vehicles, are safety devices with programmable components that protect the electrical distribution circuit. The devices prevent major electrical infrastructure upgrades by allowing the addition of a charger on a panel at full capacity.
Designed with electricians in mind, DCC units do not affect the buildings load calculation.
Should the electrical demand of the main breaker exceed 80%, the controllers prevent the circuit from overloading by momentarily turning off the power to the charger. In practice, common charging habits rarely trip the safety device as most owners plug in while sleeping when energy consumption is at its lowest.
Installing a DCC is the rough equivalent of adding a conventional oven to a home from scratch.
Devices can be wall or ceiling mounted; exterior installations require 3R configurations.
