Enhance your EV Battery design with PORON EVExtend® 

A vehicle’s operating environment is full of forces that can wreak havoc on a battery system — mechanical stress, shocks, and vibrations are all part of the equation.

While electric vehicles (EVs) do provide a much smoother ride compared to traditional gas engines, the battery pack — particularly pouch, prismatic and solid state batteries — still requires adequate cushioning and shock absorption for safe and reliable operation. All the while, these high energy batteries require consistent pressure. 

Enter the battery pad. PORON EVExtend® Battery Pad Material provides the required level of firmness required in higher-energy batteries used in EV and hybrid vehicles, offering long-term performance and functionality in your EV vehicle design. 

In this blog, we’ll outline what it does and how it will enhance battery performance and safety, and how SRP can customize it for your needs. 

What is PORON EVExtend Battery Pad Material?

PORON EVExtend Battery Pad Material is a high-performance option that’s designed to endure the stresses that are unique to the EV operating environment. 

EV battery cells expand and contract to a great degree during charging and discharging cycles. To address this, PORON EVExtend® provides the right balance of compression set resistance and stress relaxation. It’s compressible material that offers that just-right, Goldilocks level performance by: 

  • Flexing with the cycles of expansion and contraction
  • Maintaining adequate pressure to hold batteries securely in place. 

But its main advantage comes from its durability. EVExtend is built to maintain a high level of performance, maintaining that cushioning and protection throughout the life of the battery. 

Benefits of PORON EVExtend 

  • Constant pushback force: Maintains steady pressure to hold cell batteries in place. 
  • Dynamic response: Adapts to fluctuations during charging and discharging cycling. 
  • Extended life: Retains compression and maintains original thickness for the life of the battery.  
  • Temperature resilience: Operates under a wide range of temperatures, from -20 degrees Celsius to 121 C.  (Recommend constant use 90 C.)
