Energy Management Systems (EMS) provide visibility of energy usage and tools to manage, reduce and conserve consumption, It collects, stores, displays & analyzes data to optimize energy consumption of an equipment or of a property. On the other hand, Electric Vehicle Energy Management Systems, which also consists of an energy management system, focuses on the allocation of energy used in charging electric vehicles that need electricity to run. Let us take a closer look at these two management systems.
Energy Management Systems
Energy Management Systems are computer-aided systems that collect energy data from submetering devices in the field, and make it available through charts with graphics and energy analyzers for the purpose of simplifying, accelerating understanding and effective management of energy resources. They are generally used to manage energy in any type of building and help to:
- Understand energy consumption in real-time
- Detect leaks, equipment failures, outlier consumption, and other undetected faults.
- Set conservation targets through monitoring and controlling
- Develop an action plan to monitor frequently and easily
- Improve performance and energy efficiency
- Measure energy performance on fuel usage or wastage
- Plan fuel and energy purchases to minimize risks of price fluctuations
- Predict electrical system performances
- Participate in demand response programs
- Raise awareness in workforce and community on how to save water or electricity
- Increase accountability and reliability
- Reduce carbon footprint by encouraging an active participation in protecting the environment
- Save money by reducing costs and energy usage by cutting down on unnecessary consumption
- Used in Micro-grids (small scale systems)
Electric Vehicle Energy Management Systems (EVEMS)
Electric Vehicles (EVs) need access to electricity for their batteries to be charged. They typically rely on building electrical systems and or utility grids to recharge. Most buildings today have insufficient capacity to accommodate the electrical load of uncontrolled EV charging. EVEMS offers an opportunity to maximize the capacity of the existing electrical infrastructure by controlling the electric supply to the Electric Vehicle Supply Equipment- EVSE. Through the following processes:
- Connecting/Disconnecting
- Increasing/Decreasing
- Load Management
Electric Vehicle Energy Management Systems bring organizations closer to reducing the effects of gas emissions. They clear the main obstacle for EV adoption and EVSE deployment, the limited capacity in buildings, by maximizing the efficiency of electrical distribution by allocating the energy usage to charge in a smart way. EVEMS are smart systems that save natural resources that the earth so generously provides...
