Charging Stations for Electric Vehicles

Charging stations and chargers for electric cars and other electric vehicles rely on adhesives: The capacitors, voltage regulators and resistors on the charging boards must be mounted reliably resistant to shock and vibration. With additional conformal coatings, these components can be protected from temperature fluctuations, moisture and other climatic factors. 

The same goes for the connector encapsulation in charging cables: Pin sealing protects the sensitive contacts and ensures efficient and fast charging of the batteries in the long term. Adhesives, sealants and casting compounds are ideally suited for these tasks. 

The requirements for resistance to environmental influences can depend on many factors: In some cases, hard, resistant epoxy resins are required; in others, a more flexible, low-stress connection is preferred. Beside environmental conditions, the choice of casting or bonding compound is determined by factors such as substrates, surface characteristics and coefficients of thermal expansion of the materials used.

The choice of process can also affect the product recommendation. Especially UV-curing products enable a particularly efficient and rapid bonding process. For bonding applications with shaded zones that cannot be reached by light, the dual-curing products provide the most reliable curing results.
