Battery safety has hit the headlines in many countries after a series of uncontrolled fire incidents. Metis Engineering Ltd, a UK, Bristol-based company, has produced a range of innovative sensors for monitoring batteries in the automotive industry, including a battery safety sensor, which prevents thermal runaway of lithium-ion battery packs.
The new family of configurable CAN-based environmental sensors includes the products Cell Guard, H Guard, and Air Wise. The are designed to address the critical challenges of safety, emissions monitoring, and operational efficiency in Static Energy Storage, EV and HVAC industries. These sensors are set to redefine how engineers monitor and mitigate risks within battery packs and hydrogen systems.
Cell Guard provides real-time monitoring of LFP and NMC battery health, including early detection of cell venting and moisture ingress, dewpoint, pressure changes, shock loads and hydrogen generated by electrolysis within battery packs. Integrated CAN communication makes this sensor useful for advanced battery management systems to detect potential points of failure before they escalate. Metis said that Cell Guard is the key to predictive battery health management and provides vital information for Battery Passports.
H Guard is designed to detect even the smallest traces of hydrogen gas in hydrogen-powered vehicles, fuel cells, or refuelling stations, while Air Wise is a high-precision sensor designed to detect NOx and CO2 levels within HVAC systems.
Joe Holdsworth, Founder and CEO at Metis Engineering said: “Lithium-ion batteries and hydrogen technology are playing a vital role in the clean energy transition. The need for enhanced emissions control in various sectors is growing and our sensors offer critical solutions that ensure safe operations while supporting global climate goals.”
Metis Engineering’s sensors are in use in a wide range of applications including; Bloodhound LSR, Brompton Bicycles, high-performance electric aircraft, motorsport: Formula E, the World Rally Championship, Energy Storage Systems and autonomous vehicles.
