Automotive Relay Market Size

The automotive relay market size as valued at USD 16.8 billion in 2024 and is projected to grow at a CAGR of 6.2% between 2025 and 2034. An increase in global vehicle production directly drives the market development. To manufacture a new vehicle, an automaker is required to integrate multiple relays for a variety of important functions. Passenger and commercial vehicle manufacturers are incorporating more and more electronic devices to improve safety, efficiency, and convenience which increases the need for automobiles. Modern vehicles increasingly use relays for power distribution, lighting, climate control, infotainment systems, and safety systems, therefore, more relays are deployed.
 

As an example, according to Statista, global production of motor vehicles increased by approximately 10.3% from 2022 to 2023 marking a recovery from the COVID-19 pandemic which had greatly impacted the auto industry. In 2019, approximately 92 million motor vehicles were manufactured around the globe and this figure increased to approximately 94 million in 2023.
 

The increasing adoption of electric vehicles (EVs) is one of the most important trends for the automotive relay market since EVs need high-performance relays to operate onboard controlled electric and electronic systems. Unlike people who drive internal combustion engine vehicles (ICE), EV drivers depend on high-voltage relays for battery management systems, motor control, power control, distribution systems and EV charging systems.
 

Consider the example where the International Energy Agency (IEA) states that sales of electric vehicles grew to almost 14 million units in 2023. In addition, the proportion of electric vehicles rose from 4% in 2020 to 18% in 2023. China ranks first in 2024, capturing 10.1 million within total car sales. According to IEA, many countries are developing new policies and developments which might result in saving 6 million barrels of oil per day by 2030.
 

Automotive Relay Market Trends

• With the miniaturization and increasing performance of relay components, the automotive relay industry is projected to grow as a result of the multi-functional modern vehicles.
