U.S. automotive relay market size and growth rate, 2023 - 2030

Electric automotive parts have diversified, thereby increasing the number of relays used for switching; different features are required for each relay. Further miniaturization and high contact capability development are needed, especially in the Electric Control Unit (ECU), where there are restrictions in mounting space due to the presence of a cluster of relays. A high degree of reliability in relays is required from a safety point of view. Components equipped with features such as latching, low noise, and ultra-miniaturization have gained prominence owing to the need to provide switching technology for the latest generation of electronic functions in a car.

The average number of relays installed per vehicle is expected to increase over the forecast period due to the growing adoption of sophisticated electronic equipment and increased emphasis on safety and security. Switching supplementary devices required for safety, security, communications, and infotainment requires additional relays apart from those used in powertrain systems. Increased developments in PCB relays to decrease the overall vehicular weight for increasing fuel efficiency are expected to fill market growth over the forecast period.

With the automotive industry's transition from hardware to software-oriented vehicles, the average number of software and electronics per vehicle is rising rapidly. New features are integrated into vehicles using electronic devices with a wide range of application areas, such as safety management, powertrain, comfort, and infotainment, which employ automotive relays. This is expected to boost the demand in the market during the forecast period.

Passenger safety is another important factor in driving the adoption of automated automobile systems. Vehicle safety features have contributed remarkably to reducing road accidents and fatalities over the last few decades. Also, the automotive industry is working to transform consumers' driving experience. Smarter cars capable of performing self-diagnosis are gaining popularity and are anticipated to augment the market's growth during the forecast period.

The lack of standardization and highly competitive players in relay manufacturing hinder the growth of the global market. During the operation of an automotive relay, large amounts of heat are generated, and other factors, such as durability limitations and switching noise, are expected to hamper the market growth.

The growing demand for hybrid and electric vehicles with advanced, lightweight, and high-performance relays is compelling manufacturers to invest in solid-state relays compared to traditional large electromechanical relays. Thus, this is anticipated to act as an opportunity for the market to grow.

Product Insights

Based on the product, the global market is segmented into PCB relay, plug-in relay, high voltage relay, and others. The PCB relay segment captured the largest revenue share of over 64.7% in 2022 and is expected to grow at the fastest CAGR of 8.4% during the forecast period. It's used in most electronic applications such as ABS, cruise control, doors, power steering, power windows, and sunroof. In regions such as Europe and North America, they are used majorly. However, in regions such as Asia-Oceania and RoW, Tier-1 manufacturers and OEMs still prefer plug-in versions.

Furthermore, the rising demand for electric and hybrid vehicles is driving the growth of PCB relays in the market. These eco-friendly vehicles heavily rely on electronic systems for efficient power management and control. PCB relays are vital vehicle types in electric vehicle charging systems, battery management systems, and motor control units, ensuring these vehicles' safe and reliable operation.

The high voltage relay segment is expected to grow significantly at a CAGR of 8.2% during the forecast period. High voltage relays are also estimated to increase as they have many applications in electric and hybrid electric vehicles. Automotive manufacturers and OEMs integrate the relays in the vehicle’s circuit based on the respective applications. They form tie-ups and alliances with service centers to ensure proper maintenance and replacement of components.

Vehicle Type Insights

Based on vehicle type, the market is segmented into passenger vehicles, commercial vehicles, and electric vehicles. The passenger vehicles segment accounted for the largest revenue share of around 58.7% in 2022. A positive factor responsible for the segment's growth is the increasing demand for electronic e-fuse over electromagnetic alternatives due to the modernization of vehicles. Furthermore, the continuous advancements in automotive technology have led to the integration of sophisticated electronic features and systems in passenger vehicles. Modern passenger vehicles have numerous electronic vehicle types that require reliable and efficient power distribution.

The electric vehicles segment is estimated to register the fastest CAGR of 15.8% over the forecast period.Many European countries follow incentive-based programs for promoting EVs. Countries such as Germany and Austria offer tax exemptions and reductions. France and the U.K. offered bonus payments to EV buyers and discounts on insurance. Governments also provide lucrative offers to promote the selling and usage of EVs. Tax benefits are provided at the time of purchase.

Further, the extent of the exemption depends on the size of the batteries used in the vehicle. For instance, in 2021, Norway implemented a comprehensive package of tax incentives to promote the adoption of zero-emission vehicles (ZEVs). These incentives include exemptions from registration tax, value-added tax (VAT), and motor fuel taxes for ZEVs. Additionally, road taxes, ferry fees, and parking fees for ZEVs have been reduced by at least 50%. These fiscal measures have played a crucial role in driving the demand for ZEVs and increasing their market share in the country's car fleet. Government projections indicate that by 2030, the number of ZEVs in Norway could reach 1.25 million, compared to 225,000 without these incentives.

In the U.S., insurance companies provide discounts on insurance policies to customers, and utility companies offer low electricity rates. In addition, few states offer credits to electric vehicle manufacturers and buyers for their costs and purchase of charging equipment. The Federal Government offers tax credits of up to USD 7,500 for Plug-in Electric Vehicles (PEVs).

Application Insights

Based on application, the market is segmented into resistive loads, capacitive loads, and inductive loads. The capacitive loads segment accounted for the largest revenue share of 52.3% in 2022. Automotive electronics consist of semiconductor devices used to do multiple functions in a car. A car's various safety and comfort systems would not have been possible without electronics. Electronic systems drive some basic applications in modern cars, requiring relays for efficient operation. These include a door lock system, power window, air conditioner, wiper, and fuel injection.

The electronic applications are more in the passenger car than in the LCV segment. This is due to the increasing demand for premium cars with advanced features. Modern vehicles feature a multitude of intelligent systems that increase all safety aspects and driving comforts. Navigation systems with interactive traffic condition interfaces have become common even in mid-sized cars. Passive and active safety systems, such as airbags, belt tensioners, and antiskid brake/traction control, have increased the average number of relays per vehicle.

Global automotive relay market share and size, 2022

In high-spec cars, the value of the electric and electronic components sums up to almost a quarter of the total vehicle value. The wiring length can reach several thousand meters with as many connection systems between harnesses, ECU's and actuators. The vehicle's overall reliability is critical for switching lights, motors, heaters, and ECUs.

The resistive loads segment is estimated to register the fastest CAGR of 8.5% over the forecast period. Increasing emphasis on energy efficiency and sustainability in the automotive industry drives the segment growth in the market. Resistive loads, such as LED lighting and energy-efficient climate control systems, are becoming more prevalent in vehicles. As automakers strive to improve fuel efficiency and reduce environmental impact, the demand for relays in resistive load applications is expected to grow.

Regional Insights
