EV Batteries

Electric vehicle (EV) battery packs which are used in electric, hybrid and plug-in hybrid vehicles must perform reliably under a variety of conditions. They require reliable and trusted materials to perform optimally.

EV battery packs present numerous challenges for design engineers looking for ways to achieve safety targets while improving the range and battery life.

We can help improve and optimise battery pack performance with a variety of material solutions:

• Thermal Management Delay thermal propagation
• Bonding Reliably assemble components
• Environmental Seal Protect the battery from water, dust and debris
• Cooling Plate Cushion Pads Ensure contact with a consistent push force
• Electrical Isolation Control electrical charge
• NVH (noise, vibration and harshness) Bond, dampen and insulate in thin spaces
• Venting Enable the escape of heat and air

EV compression pads we work with are of particular interest to battery designers, as they offer a combination of compressive, thermal, and dielectric parameters in one solution. They offer uniform cell compression and have a great compression set resistance with minimal stress relaxation. These materials are fire retardant with UL94 V0 flammability standard and able to operate in wide range of temperatures. Their thermal runaway prevention is compliant with BESS safety standards VDE-AR-E 2510-50 and UL 9540A, among others. Our team of engineers will gladly discuss your standards and testing requirements.

Additionally, we offer high performance protection venting materials which allow pressure equalization or in case of a failure, rapid release of gases while keeping dust and moisture out of the enclosure. Designed with sintered structure, they are more robust than standard expanded PTFE filters. They are free of PFOA and complaint with (EC) 1907/2006 REACH / Regulation (EU) 2019/1021 POP.

All of our materials for batteries are available cut to a custom shape to fit your specific design requirements. Parafix is a preferred converter for leading raw material suppliers, such as 3M, Rogers Corporation and Porex, enabling us to offer the best price for top quality components. We hold a variety of ISO accreditations and make our components on state-of-the-art machines.

Parafix offers a selection of Pick and Place equipment which can automate the assembly of adhesive components, thus making your manufacturing more cost-effective and enhancing the quality.

We can help improve the range and life of EV batteries, while minimising complexity, volume and weight.
