Electrical Insulation and Shielding Solutions for EV: How Saint-Gobain Materials and ABLE’s Converting Expertise Drive Electric Vehicle Innovation
The electric vehicle (EV) industry is evolving at an unprecedented pace. Advances in battery technology, fast-charging infrastructure, and vehicle electrification are transforming how people and businesses move. As EV manufacturers push for longer driving ranges, faster charging times, and higher energy densities, the need for reliable electrical insulation and shielding solutions has become more critical than ever.
Modern EVs operate with complex high-voltage systems that generate significant electrical, thermal, and electromagnetic demands. Without proper insulation and shielding, these systems can be vulnerable to electrical failures, thermal events, signal interference, and safety risks.
To meet these challenges, manufacturers rely on advanced materials engineered specifically for high-performance EV applications. Saint-Gobain is a trusted supplier of insulation and shielding materials that help improve battery safety, charging reliability, and system performance. When combined with ABLE’s precision converting expertise, these advanced materials can be transformed into custom-engineered components tailored to the evolving needs of electric vehicles.
The Growing Demands of Electric Vehicle Systems
Electric vehicles operate with significantly higher voltages and more complex electrical architectures than conventional internal combustion engine vehicles. Battery packs, power electronics, charging systems, electric motors, and onboard control units all require dependable protection against electrical, thermal, and environmental challenges.
As EV technology continues to evolve, manufacturers require electrical insulation and shielding solutions for EV that deliver:
- High dielectric strength for electrical safety
- Thermal resistance under demanding operating conditions
- Lightweight construction to improve vehicle efficiency
- Protection against electromagnetic interference (EMI)
- Long-term durability in harsh automotive environments
- Compatibility with automated manufacturing processes
What Makes EV Electrical Systems Different?
Electric vehicles typically run on a 400V to 800V electrical system, compared with conventional road vehicles, which generally have a 12V electrical system. Such increased voltage levels also put a greater demand on reliable EV electrical insulation against electrical leakage, short circuit, and system failure. Further, compact vehicle designs push electrical components into closer proximity, meaning it is essential for proper insulation and shielding to keep them safe and operating effectively. As EV technology advances, electrical systems must also withstand higher power demands while maintaining consistent reliability under extreme operating conditions.
Understanding Electrical Insulation in EV Applications
Electrical insulation materials are used throughout electric vehicle systems.
Battery Packs
Battery packs contain hundreds or thousands of individual cells operating in close proximity.
Insulation materials help:

The Role of Shielding Solutions in Electric Vehicles
With the continued integration of increasingly sophisticated electronics in EVs, shielding sensitive parts against electromagnetic interference (EMI) becomes more significant. EV shielding solutions reduce the unwanted electrical noise created by batteries, power electronics, inverters, and charging systems to help provide a stable vehicle system communication path. Good shielding also helps meet automotive electromagnetic compatibility (EMC) requirements and provides better system reliability.
