The challenge in energy management systems

  • By providing better information to users regarding energy consumption, better decisions may be made to assist in energy consumption reduction
  • Global Energy Management Systems Market size is expected to reach US$ 62.3 billion by 2023 (Market&Market)
  • Industrial energy management system market, as indicated by Future Market Insights, is projected to reach a market value of over US$ 50,300 Mn by the end of 2028
  • Some of the challenges of such systems in the market is the desire to strike a balance between the complexity of the system, the costs, and the precision
  • Reduced complexity will lead to lower costs, but will also lead to lower precision, and without the proper precision, the information provided loses its value
  • Most existing systems use high precision sensors such as current transformers
  • Need to improve existing systems for measuring energy consumption in various environments (industrial, commercial and residential)

System for measuring of electrical energy consumption

  • A system for measuring electricity consumption of an environment having a plurality of electrical appliances, including plurality of measuring devices for connection to a wire between one of the plurality of electrical appliances and one of a plurality of corresponding circuit breakers
  • A non-invasive, low power consumption miniature wire/wireless current sensor
  • The sensor measures the magnetic field (Hall effect) for monitoring the flow of electricity at multiple levels of granularity (utility meters, electrical panels, subpanels, and equipment)
  • Wired or wirelessly send the information back to a central gateway
  • The central gateway is responsible for receiving information from multiple sensors, processing it and routing it to an analytics platform
  • This allows detailed real-time and historical energy usage data observation through various type services: cloud-based analytics software or advanced metering infrastructure
  • The gateway can be integrated in an existing home/commercial/industrial power usage display architecture
  • Technology developed by prof. Ghyslain Gagnon at École de Technologie supérieure

Competitive advantages

  • Easy to install and setup: Tens of sensors can be deployed in a few minutes
  • Compact overall size: 2”w x 1.6”h x 0.4”d (5cm x 4cm x 1cm)
  • Real time data collection: an optimized proprietary protocol based on ZigBee and MiWi IEEE 802. 15. 4 standards
  • Low power consumption: at one measure per second and one data transfer every two minutes
  • Non-invasive: the casing fits easily to an electric wire without need for any disconnection
  • High repeatability: auto-calibration algorithms provide a precision of around 99.98% (stdev of 0.3A with a measurement cycle of 10s)
  • Cost effective: sensors cost <$5 for 1M+ units and gateways’ cost < $50 for 100K + units
  • Wide current measurement range: 0-100A and 0-230V, supporting both US and EU AC frequencies

Market applications

  • Applications in industrial, commercial and residential facilities markets as a standalone product or integrated in an existing commercial solution

Business opportunity 

  • PCT has been filed on April 29th 2013
  • US patent has been filed on November 10th 2014
  • An industrialized and ready for commercialization technology
  • A proven product already deployed and tested in various installations
