In the Electric Vehicle industry, the hermetic sealing of components such as contactors, relays, circuits, and rapid charging systems offers several benefits, particularly in applications where thermal management and protection from environmental factors and long-term reliability are crucial.
Here are some of the key advantages:
Environmental Protection:
Hermetic sealing, vital for effective thermal management, provides a high degree of protection against environmental factors such as moisture, dust, dirt, and gases. This is essential for electronic devices used in harsh or unpredictable environments, including electric vehicle and aerospace applications.
Extended Lifespan:
Hermetic seals prevent external elements from entering the device, which can lead to corrosion and damage over time. As a result, hermetically sealed electronic devices tend to have a longer lifespan and improved reliability within electric vehicles.
Reduced Maintenance:
Hermetically sealed devices typically require less maintenance since they are less prone to wear and tear caused by environmental exposure. This is particularly important in critical applications where servicing may be difficult or costly.
Improved Performance:
Protection from environmental factors, crucial for effective thermal management, can lead to more stable and consistent performance of electronic components in electric vehicles. It helps maintain the functionality and accuracy of sensors, transducers, and other sensitive elements within the vehicle.
Inert Environment:
Hermetic sealing can create an inert internal environment, free from contaminants and gases, crucial for precise thermal management. This is particularly beneficial in applications like high voltage relay potting, staking of Li-ion battery cells, and encapsulation of motor windings.
Reliability in Extreme Conditions:
Hermetically sealed devices, essential for efficient thermal management, are well-suited for extreme temperatures due to weather which directly affect the performance of the electronic components in a vehicle.
Improved Safety:
Hermetic sealing can enhance safety in applications where failure could have serious consequences, such as in automotive control systems for electric vehicles.
