Electric vehicles can significantly reduce the emission of greenhouse gases. Consumers' preference for EVs because of affordability, less fuel cost, and environmental responsibility is increasing the demand for EVs. With increasing EV demand, wiring harnesses and connectors for the electric vehicle market have seen significant development. Therefore, worldwide EV adoption would boost market growth, especially as an electric vehicle needs three times as many wires as a conventional ICE vehicle. Furthermore, the expansion of EV infrastructure would provide further demand.

Growing Need for Automotive Safety Systems

Automotive active safety is a protective system that aids drivers in maintaining control of their vehicles, preventing or reducing traffic accidents, and improving their driving experience. The rise in consumer safety concerns and government-sponsored safety programs has increased the demand for trustworthy connectors in numerous vehicle systems. For example, car safety systems such as seatbelts, airbags, and brakes require a connection system with a retainer and a safety restraint system connector. As a result, the rising demand for vehicle safety systems directly impacts the need for wiring harnesses and connectors for electric vehicles, propelling the market expansion.

Global Wiring Harnesses and Connectors for Electric Vehicles Market Restraint:

Increase in Copper Prices

A recovery in global economic activity following a COVID-19 pandemic-induced recession, major stimulus packages in the U.S., and an increase in the use of green mobility (electric cars) have all contributed to the rise in demand for the industrial metal copper. Copper's widespread industrial use allows us to gauge the health of a nation's economy, and rising copper prices, according to analysts, indicate that the global economy is improving.

Most OEMs use copper as their prime metal choice to manufacture wiring harnesses owing to its flexibility and ease of molding. Moreover, the amount of copper used in an EV is two times that used in a traditional vehicle. Therefore, copper prices in the future are bound to ramp up, which would hinder the growth of the wiring harnesses and connectors market for EVs.

Global Wiring Harnesses and Connectors for Electric Vehicles Market Opportunities:

Weight Reduction of Wiring Harnesses and Connectors

In line with the power increase of the HEVs, PHEVs, and BEVs, a larger current is required, which has led to the expansion of the cross-section section of the wires. In consequence, wire weight gain is becoming an issue with EV manufacturers. The wire weight decrease is necessary to enhance the range of electric vehicles. Therefore, companies can use bulk aluminum wire to overcome these difficulties.

The aluminum wire for the cable harness protected by the tube requires flexibility for durable vibration and high-power conductivity. The weight gain problems brought on by using thicker copper wires can be resolved with the new aluminum material that satisfies both requirements. Moreover, the aluminum wire has a more significant temperature working range, making it all the more suitable for electric vehicles. Such factors create opportunities for the market's growth.
