To maximize the energy efficiency and driving range of electric vehicles (EVs), manufacturers are using higher voltage systems, which generate higher temperatures than conventional vehicles.
This means that choosing automotive materials that can stand up to high temperatures, high voltage, and longer periods between inspections is essential in the design of EVs.
Chemours Viton fluoroelastomers offer extruders, compression, and injection molders high-performance benefits for electric vehicle (EV) high-voltage cables.
High-voltage power cables are used for an EV’s electrical system, as they carry the high-voltage direct current (dc) power from the battery pack to the motor and power electronics. These cables are exposed to extreme temperatures and harsh chemicals, such as battery acid, which could cause them to degrade over time.
Viton is known for its excellent resistance to high temperatures, chemicals, and fuels. It’s been routinely used in applications in the automotive and aerospace industries that require high temperature and chemical resistance, such as seals and gaskets in fuel injection systems. But e-mobility technology can also benefit from Viton fluoroelastomers by insulating and sheathing high-voltage power cables.
Viton fluoroelastomers used in high-voltage EVs offers volume resistivity and dielectric strength. With mineral filled Viton compounds can reach a volume resistivity > 1013 Ohm*cm — while exhibiting dielectric strength above 20 kV/mm.
Features
Viton fluoroelastomers lend a unique combination of properties for superior reliability and long-lasting durability in high-voltage EV cable applications, including:
- Temperature resistance
- Volume resistivity
- Greater flexibility and elasticity
