Charging

To enable widespread adoption of electric vehicles (EVs), manufacturers must prioritize advancements in charging capabilities. Consumers expect EV charging stations to deliver fast charging speeds, operate reliably in harsh environments, and seamlessly integrate with renewable energy sources – all while maintaining the highest safety standards. These complex requirements create significant engineering challenges that demand innovative material solutions.

Modern EV charging stations must efficiently charge batteries while managing heat, electromagnetic interference (EMI), environmental exposure, electrical insulation, and mechanical stress. Without proper materials, these systems face critical risks: overheating that degrades performance, EMI that disrupts operations, electrical shorts that compromise safety, and premature component failure from mechanical stress and corrosion. Failure to address these risks can result in increased downtime, higher maintenance costs, and reduced consumer confidence in EV technology. 

Qnity’s portfolio of advanced materials are designed to address these challenges and enable EV charger protection. For example:

• Thermal management materials efficiently dissipate heat from charging componentry, maintaining optimal operating temperatures and reducing the risk of dangerous overheating. 
• Laminates, films, and metallized connectors protect charging equipment from corrosion, mechanical stress, and environmental factors, improving the reliability and long-term durability of charging systems. 
• Specialized EMI shielding and absorption materials enhance clean signal transmission and protect sensitive components from EMI.
• High-performance electrical insulation materials provide critical safety barriers in high-voltage EV charging environments, reducing the risk of electrical shorts and arcing that can lead to fires. 

As manufacturers transition from today’s 400V battery systems to 800V systems that enable faster charging and higher performance, thermal, EMI, electrical, and mechanical challenges will continue to grow. Qnity’s portfolio empowers design engineers to develop safer, faster, and more sustainable EV charging solutions.
