Silicone adhesives for EV charging station assembly

In this article, we explore the best silicone adhesives used to assemble electric vehicle charging stations.

Electric vehicle charging station

An electric vehicle charging station is a unit capable of charging the batteries of plug-in electric vehicles. Electric vehicles will account for 12% of all vehicles on the road by 2030.

With this exponential increase in demand, electric vehicle charging points are becoming very common structures around us. Increased demand requires high-quality adhesives and sealants to assemble them, increase reliability and reduce maintenance and repair issues.

How silicones can optimise the production of electric vehicle charging stations

DOWSIL™ silicone adhesives and sealants have a long proven history of providing protection and thermal stability, as well as improving efficiency and reducing costs within the application process. In addition, silicone’s excellent weather resistance properties allow EV charging stations to be located anywhere, providing reliable performance regardless of the harsh conditions they endure.

Silicone technology is able to withstand UV radiation, maintain excellent flexibility over a wide temperature range, form watertight seals and exhibit dielectric properties. All these advantages make silicone a perfect material for sealing and assembling electric vehicle charging stations.

Types of silicone products applicable to charging stations

Silicone products applicable to electric vehicle charging stations include: foams, adhesive sealants and conformal coatings.

Foams

DOWSIL™ foams are excellent lightweight alternatives to traditional sealants and encapsulants, paving the way for more efficient processing. A common application for silicone foams is battery pack shielding.

Sealing adhesives

Silicone adhesives are used in a variety of applications, including vibration control of large capacitors, electromagnetic shielding, electronic component assembly and housing sealing. DOWSIL™ silicone adhesives are long-lasting and solvent-free.

Conformal coating for electronic protection

Silicone conformal coatings offer excellent stress reduction when used on delicate PCBs (printed circuit boards) during thermal cycles. Various application requirements can be met using DOWSIL™ conformal coatings thanks to their wide range of different viscosities.

Applications of silicone products on electric vehicle charging station

To meet the various assembly and protection requirements of electric vehicle charging stations, there are numerous silicone products with specific characteristics. Below, we explore the main types of DOWSIL™ solutions used in the sector.

Housing

Most charging stations consist of a metal frame that acts as a structure and covers that enclose this frame.

This set of covers can be locked/secured to the frame. Since most of these stations are exposed to weathering, the covers must be sealed.

Electronic protection and PCBs

Silicones enable electric vehicle charging station manufacturers to better protect their charging points from dust and moisture for more reliable performance over an extended period of time.

Due to the harsh conditions endured by charging points, it is essential that manufacturers guarantee reliable performance over a long period of time. 

Damp and dirty environments such as garages and car parks are notorious for faulty electronic products, making it essential that key players in the industry cover all aspects of protection, from circuit boards to product enclosures.

DOWSIL™ products for electric vehicle charging stations

Silicone products are used in various structural and electronic components of charging stations, improving their reliability and durability. Let’s see how they are applied in key points of the infrastructure.
