Screws for electric vehicle charger assembly

Electric vehicle (EV) technology and new concepts in electromobility are driving us towards a future of low carbon transport at an ever greater pace. It is, of course, a revolution in mobility that will also require easy access to EV chargers in public places and at home, which is why the growth in EV adoption crucially depends on the industry’s ability to meet this battery charging demand.

Mirroring the approach of vehicle manufacturers across the globe, who are innovating in all areas of vehicle design by utilising advanced screws for joining lightweight plastics, the rapid scale up of EV wall charger production is moving forward with greater efficiency and continuously improving quality.

With the EJOT range of screws, optimising the assembly of wall charging units is easy. The capability of our fasteners to streamline production through their versatility and provide long term cost savings, whilst also delivering higher joining performance, will help EV charger manufacturers to satisfy the growing market sustainably.

At EJOT, we understand the multiple design objectives of EV wall charger designers and manufacturers extremely well, because we serve numerous other industrial sectors with comparable challenges – sectors where assembly uses similar materials at similar volumes. So finding a solution that works for the 50 or so fastening elements used in the assembly of every EV charging station is readily available within our screw range.

We have particular expertise in reliably joining plastics, composite materials and foams. Our range spans metal screws for plastics, plastic screws, friction-weld systems, plastic fasteners and removable fasteners – all of which are designed to provide high strength joints to ensure the finished product achieves the robustness and longevity sought in the design.

One EJOT screw that is particularly well-suited to EV charger assembly is the EVO PT S. Such are the capabilities of this screw that it can offer huge scope for greater standardisation throughout product assembly – one screw size can be used for multiple fixing points. And it is a product with proven product performance too.

The EVO PT S screw for direct fastening in plastics provides its standardisation potential due to an insertion-depth-independent installation torque. Where normally various screw dimensions for different fastening points in the wall charging station are used, with EVO PT S only one screw size is required.

By reducing the number of different screws required, manufacturers of EV chargers can simplify installation, ordering and stockholding. Streamlining all these process engineers-out cost and potentially improves productivity of the whole operation. And in addition, the EJOT EVO CALC® prognosis program is also available to designers to use in the development phase for advance computation of the screw joints – this helps saves time and costs.

EVO PT S typifies how using EJOT screws to both reduce the number of parts needed and achieve higher screw performance means greater ROI for EV charging unit manufacturers.
