Video: Enhancing EV battery packs with foams, adhesives and high-performance thermal materials
Effective thermal management is one of the most critical aspects of EV battery pack design. Engineers must not only ensure efficient heat dissipation during charging and discharging cycles but also maintain uniform temperature across all cells to optimize performance and extend battery life. This requires integrating advanced materials—such as flame-retardant foams, adhesives, and gap fillers—that… Read more »
