E-Mobility

Thanks to innovations in li-ion battery technology, fully sustainable transport via land, sea and air is now a realistic goal. eMobility is gaining momentum globally, transforming transportation from industrial freight down to micro-mobility.

As this e-revolution accelerates, ensuring li-ion battery safety and performance are more crucial than ever. Being able to prevent and mitigate thermal runaway is a particular concern for li-ion battery designers. At OE, we take pride in driving battery safety forward with advanced pressure relief solutions that offer both ongoing pressure equalization and emergency pressure relief.

In-House Design and Engineering

‍We design, build and test custom rupture discs to protect the lithium-ion battery cells, packs, and enclosures used in electric and hybrid vehicles. Our in-house design and engineering team has decades of experience, and specializes in creating custom solutions for environments with unique requirements.

Design Flexibility

‍Whether it's the harsh conditions of sea travel, the fluctuating altitudes and temperatures in aircraft, or the compact spaces within electric vehicles, we understand each project is unique. We will work with you and your teams to create a one-off design that integrates seamlessly with your requirements. We know that requirements can change rapidly - and sometimes dramatically! - in an R&D environment, so we approach any rupture disc request as a new project with scope to flexibly alter it as requirements develop.

Responsive Support

‍We provide on-site visits, face-to-face interactions, and immediate technical assistance through a small, agile team.

Space Optimization

We are experienced at addressing the space constraints associated with integrating lithium-ion batteries into the powertrains and other components of electric and hybrid vehicles. Our specialist rupture discs feature low-profile and space-saving designs to minimize the pressure relief footprint while maintaining full efficiency. Our Dual-Gard breather membrane technology combines pressure equalization with emergency pressure relief in a single device. Eliminating additional components means you have less inventory to manage and fewer components to assemble. This enables a less expensive battery enclosure, while the simple and clean battery design is quicker to assemble and easier to integrate.

Our OE Lion rupture disc range for eMobility offers standard and custom designs. We specialize in working with R&D teams to create a unique pressure relief solution that meets your specific requirements. Our designs help you overcome the constraints of lithium-ion battery design with ease. A customizable range of sizes, burst pressures, disc profiles and mounting arrangements allow us to easily integrate pressure relief into your design, whether you require:

• Low or very low pressures
• Low profile discs
• Very small discs
• Minimal space footprint
• Vent directly to atmosphere
• Vent to ductwork, exhaust systems or piping
