They act as a battery impact protection barrier to enhance consumer safety and reduce battery-related warranty costs. Boyd’s wide variety of closed and open cell foam options are highly resilient and meet the needs of many different temperature and environmental exposure applications.
Protect EV batteries against collision impact, harsh road conditions, and temperature extremes with rugged, resilient compression pads. Battery compression pads layer between battery cells and around the battery module to compensate for swelling forces and mechanical shock, friction, and extreme road vibration.
Sealing the EV battery enclosure protects the battery and cells against liquid, gas, and particulate intrusion to ensure long battery life. Leverage specialty materials and smart gasket design to both waterproof and seal EV battery housings, eliminate noise, vibration, and harshness (NVH), and optimize reliability and performance.
The safety of first responders is as important as that of the vehicle’s occupants. While EVs and their battery casings are designed to prevent any penetration of the pack that disrupts the cells in a crash, that is not always possible and the HVIL cannot eliminate the resulting hazards.
Proactively absorb impact, vibration and movement in the battery. Efficiently dissipate battery cell heat. Incorporate a flame or heat barrier in cell design to quickly isolate extreme heat or fire in the unlikely event battery safety design features fail to prevent cell-to-cell propagation.
Electrical safety depends to a large degree on the ability to isolate the battery and the entire high-voltage circuit, with different solutions for different situations, one battery developer says.
