The Automotive Division of the Society of Plastics Engineers (SPE) has unveiled the finalists for its 52nd annual Automotive Innovation Awards. The safety category features entries from GM and Ford, two from the former and one from the latter. One of the GM entries is profiled below. All of the winners will be announced on Nov. 8, 2023, during the awards gala.
Intumescent Terminal Covers
OEM make and model: 2023 General Motors Co. Cadillac Lyriq and GMC Hummer
Tier supplier: Auto-Kabel Group
Processor: Molded Precision Components
Material supplier: Pyrophobic Systems
Material: Lithium Prevent 200 polyvinyl chloride (PVC)
Process: Injection molding
A specially formulated flexible and intumescent PVC is designed to prevent arcing during thermal runaway events in high-voltage EV batteries. The high-temperature, high-voltage insulator is used to injection mold various terminal caps and barriers. Safety is increased during thermal runaway since the material maintains high dielectric strength, reducing arcing risk and ignition of gases, and forms a structured char barrier, helping reduce spread of fire from one module to another.
