Challenges In Wiring Harnesses Connectors Electric Vehicles Market

The market for wiring harnesses and connectors for electric vehicles is dramatically contending with increasing complexities in electronic systems in vehicles; this comes along with all existing types of EV platforms. On the one hand, high-voltage and data-hungry architectures require lightweight yet very durable wiring that can handle more advanced power load capacities and connections. In this regard, it is a major hurdle to standardise wiring harnesses and connectors across the many vehicle models and electronic architectures, making it even more complex for suppliers and automakers in the design, manufacture, and integration processes. In other words, the fast pace of change in technology, along with the demand for miniaturisation, the production of heat-resistant recyclable materials, and so forth, is making manufacturing quite difficult to understand. All of these factors greatly increase the production costs and add to the complexity of the supply chain. Variability in regulation from region to region in the requirement standards frequently serves as a negative aspect, combined with inadequate EV infrastructure in certain markets and also a high dependence on imported components. All these factors, adding to the present challenges, would be trouble for global suppliers in the fast-evolving market.

Key Target Audience

The Wiring Harnesses and Connectors market for Electric Vehicles (EVs) targets primarily automobile original equipment manufacturers (OEMs) designing and manufacturing electric vehicles. These OEMs are the end consumers for wiring harness and connector vendors, as they integrate such components into their EV platforms in vehicle assembly. They drive specifications, volumes, and delivery schedules based on their production schedules and the specific electrical architecture of their EV models, which range from battery electric vehicles (BEVs) to plug-in hybrid electric vehicles (PHEVs).,, Apart from OEMs, the market indirectly addresses the interests of Tier 1 automotive suppliers developing and supplying systems integrated into EVs, such as batteries, power electronics, and charging systems. Such Tier 1s often purchase wiring harnesses and connectors and integrate them within their larger modules supplied to OEMs. As the EV aftermarket that supports maintenance and repair widens, there will be a growing consideration of independent repair shops and service centers as increasingly important second customers for replacement wiring harnesses and connectors. The sale of such wires and connectors will continue to be driven by the vehicle manufacturers themselves at the start and for quite some time.

Merger and acquisition

In recent years, the market for wiring harnesses and connectors for electric vehicles has recorded a lot of mergers and acquisitions (M&A) due to the fast-paced nature of the industry with rising demands for advanced and sustainable solutions. In September 2024, Luxshare Precision acquired a 50.1% stake in Leoni AG and full ownership of Leoni K for EUR 525.41 million, a strategic play to further its automotive presence. This will be a natural extension of Luxshare's core business in consumer electronics, with the objective being to exploit leverage from the sharing and synergy of resources in building a competitive edge in the global automotive wiring harness market. Furthermore, in June 2024, Sumitomo Electric announced the expansion of its production capacity in Mannheim, Germany, for the local manufacture of the highest-end 525 kV HVDC cables. Along with this, the company acquired a majority stake in Südkabel, a distinguished German high-voltage cable manufacturer. These strategic measures are complementary to the German government's net-zero aspirations and are aimed at developing Sumitomo Electric's record of accomplishment in high-voltage cable development. >
