Market Dynamics:

Growth Drivers: Electric Vehicle Production Growth and Voltage Architecture Transition

Growing production of battery-electric and plug-in hybrid vehicles is the key factor driving the Automotive High-Voltage Connectors Market, given that all such vehicles need a number of high-voltage connectors which are used in batteries, inverters, chargers, and motors of an electrified car, and these connectors simply does not exist in cars running on a conventional internal combustion engine. Such fundamental changes in vehicle architecture translate the growing production volumes of EVs into a growing content of connectors per vehicle, thus generating a solid growth tailwind regardless of any developments in the vehicle market. The strategy of automakers toward electrification in different regions will continue supporting this trend in the future.

Another factor driving the growth of the market will be the industry-wide move towards 800V and even higher voltage electrical systems from 400V systems, as manufacturers opt for higher voltage systems for their ability to achieve faster charging capability and lightweight vehicles using thinner cables. The new architecture will create a demand for newer types of connectors designed to withstand higher currents and heat loads, which will provide premium product solutions for those suppliers who manage to qualify themselves in the manufacture of advanced high-voltage connectors before others.

Restraints: Design Qualification Complexity and Raw Material Cost Volatility

Qualification testing needed for safety and reliability of automotive high-voltage connectors is one of the significant factors limiting market growth, because such connectors have to be qualified for vibrations, temperature cycling, moisture ingress, and electrical isolation capabilities in automotive conditions before obtaining automaker approval. Such qualification process prolongs the duration of product development and raises the bar on entering the market for smaller competitors, who wish to participate in automaker platform programs.

In addition, cost fluctuations of raw materials, such as copper and special engineering plastics, which are essential materials in manufacturing high-voltage connectors, pose additional cost challenges for suppliers during price negotiations with automakers. Smaller suppliers with a smaller scale of procurement are relatively more exposed to the cost’s changes compared to larger and more diversified manufacturers of connectors. Until cost fluctuations of raw materials will subside, some of the smaller suppliers will continue being concentrated in smaller-volume connector applications.

Opportunities: 800V Architecture Adoption and Commercial Vehicle Electrification

Fast-tracking the adoption of 800V and above voltage vehicle architectures presents a huge opportunity as suppliers who can qualify new connector designs before OEMs introduce their platforms will be able to achieve premium pricing and contracts based on vehicle life cycles. Suppliers who are developing 800V connector systems have the advantage of becoming leaders in the industry as the number of OEMs adopting higher voltage vehicle architectures increases.

There is an increased electrification of commercial vehicles such as vans, buses, and medium-duty trucks. This presents yet another path to growth as commercial electric vehicles need a higher number of high voltage connectors as compared to passenger vehicles due to large batteries and power distribution needs. There is great opportunity for suppliers to capture demand in this relatively untapped market through rugged, high current connector designs.
