In recent years, with the acceleration of the automobile industry to the development of new energy-intelligent vehicles, the global sales of new energy vehicles began to continue to rise. In the face of more and more demands for new energy vehicles, the safety, stability, service life and endurance of the power battery system of new energy vehicles are undergoing constant tests.
Silicone rubber as a thermal conductive filling material with excellent thermal conductivity, insulation, and compression performance, shoulders the task to solve the “high temperature” problem generated by the power battery system for new energy vehicles. As new energy vehicle manufacturers pay more and more attention to the safety of power battery systems. The application of silicone rubber in power systems and automotive components is becoming more and more extensive and important.
Silicone rubber is used to reduce operating temperature, improve performance and optimize environmental sealing performance. Silicone rubber is widely used in various components of electric vehicles (EVS).
- Battery safety components
- Seal and gasket
- Airbag seal
- Radiator seal
- Window seal
- Performance Hose
The environmental benefit grows the popularity of electric vehicles, and so does the demand for silicone rubber that can strengthen the performance and safety of electric vehicles’ operation.
Silicone rubber offers environmental endurance and resistance to negative factors in the long run. So now more and more automotive manufacturers tend to pick silicone rubber as their material choice.
- High resistance to ozone, water, sunlight, and ultraviolet rays
- Tensile strength
- Well-performed Flexibility and temperatures resistance
- Excellent compression resistance to permanent deformation
- High electrical insulation
It is also flexible, safe, non-toxic, and high quality, which is popular and practiced in different fields, including aerospace, medical, health care, pharmaceutical, electronic, household, etc.
But how does silicone rubber improve the safety of electric cars? Several examples can support the questions.
The Advantage of Safety
There are many benefits to using silicone rubber to optimize the safety of electric vehicles, including:
- Maximum control of the thermal runaway
- Good thermal stability up to 230°C
- Strengthening fire prevention safety
- Reliable material quality
- well-adapted ability in harsh conditions
- Resistance to UV, Ozone, shock, moisture, and corrosion
All of these advantages are indispensable to the safety and performance of electric vehicles.
Electric vehicle manufacturers take safety very seriously and work by strict design regulations that are in place to ensure that electric vehicles can be safely driven and charged.
This is a major safety challenge for many electric vehicle manufacturers to prevent shock and vibration.
Addressing the issues of noise, shock and vibration can not only paves the way for smoother, quieter driving but also provides safer driving for drivers and passengers. Solving these problems will also help optimize the service life of electric vehicles and their component vehicles.
Silicone is an excellent vibration-damping material that is well-suited to help optimize noise and vibration control for electric vehicles, thereby improving safety and performance.
Thermal management of electric vehicles
Thermal management in electric vehicles is extremely important to ensure that thermal runaway does not occur inside the soft-pack battery. By eliminating any heat generated by the core components of the vehicle, the risk of overheating is reduced.
To ensure that components do not overheat and endanger safety, the heat generated in an electric vehicle must be dissipated quickly and efficiently from the core components.
Silicone rubber can be used to support the thermal management of electric vehicles due to its heat resistance properties, wide operating temperature range, and ability to provide thermal stability. It can still withstand extreme temperatures from high to low, with little change in physical properties
EV charging Safety
The unique property of silicone rubber helps secure EV chargers, protecting charging points from water, dust, and moisture damage, and ensuring that internal components such as PCBs provide reliable performance while minimizing risks such as overheating and fire.
In addition, silicone‘s surprisingly strong tolerance to weather and other factor make electric vehicle charging points can be used everywhere.
Silicone rubber is also popularly used to insulate EV battery cables due to its insulation and flame-retardant properties. Since the silicone rubber can withstand significant temperature changes, the cable can withstand the heat generated by the charger’s high voltage output.
