Metis Engineering Ltd, a UK-based company in Bristol, has developed a suite of innovative sensors to address the pressing challenges of battery safety and emissions monitoring in industries like automotive, energy storage, and HVAC. The new range includes Cell Guard, a sensor that provides real-time monitoring of battery health, detecting issues like cell venting, moisture ingress, pressure changes, and hydrogen generation. Integrated CAN communication allows for early detection of potential failures, crucial for advanced battery management systems. H Guard, another sensor, specializes in detecting hydrogen gas in vehicles and refueling stations, while Air Wise monitors NOx and CO2 levels in HVAC systems. Founder Joe Holdsworth emphasized the significance of lithium-ion batteries and hydrogen technology in the shift towards clean energy. The sensors from Metis Engineering are critical in ensuring safe operations and supporting global climate goals by offering solutions that enhance emissions control. These sensors are already in use in various applications, ranging from high-performance electric aircraft to motorsport events like Formula E and the World Rally Championship, as well as in energy storage systems and autonomous vehicles. The innovative technology provided by Metis Engineering is set to revolutionize how engineers monitor and mitigate risks within battery packs and hydrogen systems.
