What is An EVEMS or Energy Management System? Why do I need one?

1. Electric Vehicle Energy Management Systems (EVEMS): These systems are responsible for controlling the electricity used by electric vehicle charging equipment to ensure they do not overload (or take too much power from) any part of the electrical structure in a home or building.

2. Why Do I Need One?: It saves the cost of upgrading an electrical panel or service. Why? When you charge an electric vehicle (EV), it typically requires 32 to 80 amps to operate. If you directly connect the EV charger to your home’s electrical panel without an energy manager, it likely would overload the electrical system. That is because most homes have electrical supply limitations (usually 60, 100 or 200 amps), and adding an EV charger could exceed that limitation at peak usage times. This can cause power outages, damage or even a fire.

3. The Solution: Instead of upgrading your entire electrical panel at great cost, you can use an EVEMS or Energy Management System. This system intelligently manages the power flow to the EV charger. It can connect or disconnect, power as needed to maintain safety. By doing so, it is a code compliant way of preventing the overloading of your panel and ensures safe charging without requiring an expensive panel upgrade. Its like a 24 hour guard for the electrical structure in your home.

In summary, using Energy Management is a cheaper, and simpler way of charging your electric vehicle while keeping your home’s electrical system safe and secure! It will save money and time when installing EV chargers.
