EV SAFETY MONITORS
Nexceris’ Sensors Unit has been developing safety monitors to detect hydrogen and lithium-ion emissions for years.
In July 2025, Nexceris, sold its Li-ion Tamer® off-gas monitoring solution to Honeywell. Li-ion Tamer® is the industry’s premier technology for preventing thermal runaway events in lithium-ion (Li-ion) batteries.
The Li-ion Tamer® products were developed by the dedicated team at Nexceris. Our dual passions for safety and supporting the growth of clean alternative energy led us down the path of the Li-ion Tamer® development.
First conceived as a safety device for nuclear submarines, the product has evolved into products and conceptual products for the marine, transportation, grid storage, residential energy, and laboratory safety markets. Our work with the U.S. Navy resulted in an expanded team of developers that included DNV-GL and Beckett Energy Systems in work funded by the U.S. Department of Energy. This was followed by several efforts aimed at making our service ships safe. More recently, we worked with the Federal Aviation Administration to study ways of detecting battery issues in aviation.
Nexceris: Advancing the Safety of Electric Vehicles Through Innovation
As the global automotive industry accelerates toward an electrified future, ensuring the safety of electric vehicles (EVs) remains a critical challenge—especially when it comes to the fire risks posed by lithium-ion batteries. Recognizing these concerns, Nexceris is leading the charge in EV safety with its pioneering Li-ion Tamer® EV technology.
At the heart of Nexceris’ mission is a commitment to protecting lives and assets through proactive battery safety solutions. The Li-ion Tamer EV system is the industry’s most comprehensive early warning solution, uniquely capable of detecting all major types of lithium-ion battery failure—including thermal runaway precursors that other systems miss. This game-changing capability empowers EV manufacturers to act before a critical event occurs, significantly reducing fire risk and increasing consumer confidence.
Collaborating with Global OEMs for a Safer EV Ecosystem
Nexceris works closely with top-tier automotive OEMs around the world, integrating Li-ion Tamer sensors directly into their EV battery packs. This collaboration ensures that safety is embedded at the design level—not retrofitted as an afterthought.
Our sensors are engineered for seamless integration:
- Control board-mounted configurations offer system-level visibility and integration with battery management systems.
- Packaged sensor units come with built-in connectors for easy installation and rapid deployment.
By equipping EV platforms with our advanced detection technology, Nexceris supports OEMs in meeting stringent safety regulations, advancing sustainable mobility, and achieving their electrification targets without compromise.
In 2010, NTM Sensors was formed as a business unit of Nexceris to actuate our vision of providing specialized sensing systems for these neglected markets and providing better sensing options to manufacturers. Through our extensive work in emerging technologies and environmental markets, we recognized a large deficiency in quality safety sensors and monitoring systems suited for these markets. For such tailored markets, like the ones in which we work, you need tailored products. So, we resolved to create innovative and highly selective sensors designed specifically for the advanced technologies and environmental markets in which we were working.
NTM Sensors leveraged its unique chemi-resistive sensing technology to launch its initial product – the NTM SenseH2® hydrogen sensor. It has since produced the NTM SenseH2®-R hydrogen sensor and has several more products in the works.
