MINNEAPOLIS--(BUSINESS WIRE)--Donaldson Company, Inc. (NYSE: DCI), a worldwide manufacturer of venting solutions for automotive systems, now offers the Dual-Stage Battery Vent. This new high-performance battery pack vent helps provide protection from water, dirt, contaminants and automotive fluids, while equalizing pressure of the battery pack—two functions that support the life of batteries and their enclosures.
“Our new Dual-Stage Battery Vent is designed to meet the unique requirements of automotive battery packs: the need to protect the battery pack housing from excess over- or under-pressure under normal conditions, and the need to expel large amounts of gases quickly if a thermal runaway event begins within the battery pack,” said Nathan Malek, general manager of Donaldson Global Venting Solutions.
The first stage of the Dual-Stage Battery Vent equalizes pressure while preventing the ingress of water and contaminants. Second stage venting activates if rapid pressure and heat build-up occur, fully opening the vent and allowing expanding gases to escape, which deters further damage to the remaining battery cells.
The Dual-Stage Battery Vent includes valuable design improvements over current one-way valves. Under certain circumstances, one-way valves might unintentionally open, allowing debris or water to enter, causing sealing issues or harm to the battery pack. The Donaldson streamlined Dual-Stage Battery Vent design avoids the use of a valve, rubber flap or any other mechanical device. Instead, it attaches directly to a housing via a quarter-turn bayonet installation and uses Donaldson’s proprietary Tetratex® ePTFE membrane to help keep debris and water out of the battery pack. In addition to exceptional protection from contaminants and over- or under-pressure, the Donaldson Dual-Stage Battery Vent allows gases and pressure to release during thermal runaway.
The Dual-Stage Battery Vent complements Donaldson’s growing automotive venting product line, which includes Snap-Fit, Screw-Fit, Press-Fit, Tube-Fit and Weld-Fit vents for numerous other vehicle components: from powertrains and headlights to sensors and fluid reservoirs.
