Honeywell is to co-develop sensors that help prevent the conditions leading to thermal runaway and fires in electric vehicle batteries.
It is expanding its strategic alliance with Nexceris, developer of a lithium-ion gas detection system called the Li-ion Tamer, to detect the conditions that can cause extremely high temperatures within the battery cell and can result in a fire.
Many electric vehicles today use lithium-ion batteries as an energy source, which can pose rare but significant safety risks including fires that can impact drivers on the road, homeowners who may have EVs parked in their garages and shipping handlers transporting EVs to their final destinations. To help mitigate these risks, automobile manufacturers are looking to incorporate technology to provide enhanced safety.
Honeywell develops sensors used in battery management systems to monitor the health of EV batteries, gas detection solutions used throughout the manufacturing process and electrical safety personal protective equipment. The two signed the alliance deal in 2020 for energy storage applications, combining Honeywell’s very early warning smoke detection and the Li-ion Tamer off-gas detection technology to protect facilities of any size. The two are now extending this to electric vehicles.
“As the world transitions to electric powered vehicles, automakers are faced with the need to provide lithium-ion batteries that function properly and safely during all stages of their lifecycle. At Honeywell, we are supporting this transition with ready-now solutions to help our customers mitigate safety risks as they expand their electric vehicle portfolios,” said Victor Verissimo, general manager of the Transportation line of business of Honeywell Sensing and Safety Technologies.
“By collaborating with Nexceris to develop an enhanced suite of battery monitoring sensors, we will help automotive manufacturers strengthen their battery health monitoring systems with the ability to detect thermal runaway conditions even earlier.”
“Our work with Honeywell will help us empower the global transition to electric vehicles through enhanced battery monitoring,” said Kyle Shen, president and CEO, Nexceris. “Fires from lithium-ion batteries are dangerous and often difficult to contain after they start. By combining our shared expertise in battery sensing and gas detection technology with Honeywell’s extensive manufacturing capabilities, we will be working toward offering our vehicle manufacturing customers a more advanced safety solution and meeting the growing demand for lithium-ion batteries.”
