Electric Vehicle Relays Market Size - By Product, By Vehicle, By Propulsion, By Application, By Sales Channel, Analysis, Share, Growth Forecast, 2025 – 2034

Electric Vehicle Relays Market Size

The global electric vehicle relays market size was valued at USD 3.4 billion in 2024 and is projected to grow at a CAGR of 8.4% between 2025 and 2034. With the rapid adoption of electric vehicles and government policies supporting zero-emission vehicles is driving the growth of the market. Consumer awareness regarding sustainability is also playing a major role in increasing EV sales across the globe.
 

For instance, in the year 2023, the sales of electric cars grew by 3.5 million units, which is 35% from the previous year. The peak sales figures resulted in over 250,000 registrations every week. Comparatively, only 14% of total car sales in 2022 were electric, whereas 18% in 2023. Many developed nations such as China and Europe, along with North America, have put into place strong incentives and emission targets. These policies have laid out an increasing direct demand for EV components such as high voltage relays, as every electric vehicle on average requires multiple relays for safety and operational functions.
 

The automobile industry, especially for EVs, is becoming more focused on safety, and this is resulting in an increased need for quality relays. ISO and SAE have a set standard for components of EVs, which also includes electrical safety measures. As a result of these measures, certified high-voltage relays are needed so that proper isolation from high-voltage systems is achieved, as well as protection against short circuits and enabling emergency power to be switched off. These compliance measures boost the demand for advanced relay systems on a continuous basis.
 

Electric Vehicle Relays Market Trends

The shift to higher charging voltages in electric vehicles (at 800V and beyond), there is a corresponding need for sophisticated relay solutions. It follows that manufacturers are focusing their development and production investments into building relays for these new high voltage applications safely. This movement is especially predominant in premium EVs as well as in commercial vehicles because there is a demand for faster charging and improved performance.
 

An illustration of this is available when Pickering Electronics launched their lineup of high voltage (HV) reed relays for the Indian market on June 2024 at the EV Show 2024. These include the Series 219, a surface mount reed relay, and a harnessed version of the single-in-line Series 104 reed relay rated at 5kV. Other high voltage models are being developed, such as the Series 67 and 68 family, which have former-less coils for small size 58.4 x 12.6 x 14.5mm.
 

Along with the growing popularity of EVs comes the need to build devices whose size and weight are minimized, but strength and usability are not compromised. Hence, designers are forced to work with miniaturized parts, efficient packaging, and advanced integration of high-power switching into the confined space of a vehicle’s architecture.
 

Electric Vehicle Relays Market Analysis

Based on the product, the electric vehicle relays market is segmented into contactor relay, relay module, solid-state, and mechanical relay. In 2024, the mechanical segment accounted for over 45% of the market share and is expected to exceed USD 3 billion by 2034.
 

• The subpar requirements for mechanical relays invariably include high operating voltages, temperature extremes, and constant vibrational forces which, without question, feature on electric vehicles. These mechanical relays are undoubtedly strained with life cycle and reliability hurdles that are incredibly stringent in their usefulness.
   
• In a bid to address these issues, manufacturers are combining advanced material application, precision engineering, and extensive testing to create relays that can withstand more than a million switches. This construction drastically increases the safety and performance of the vehicle throughout its lifetime.
   
• As an example, in May 2024, Japan-based FCL Components released the FTR-E1-HC, a high switching voltage relay which is both lightweight and designed for automotive and power applications. The FTR-E1-HC has load terminals with no polarity constraints and uses just 1.2 watts when switched on with the coil voltage. This specific design negates the need for a holding coil drive circuit, which significantly reduces costs and utilization of space.
   
• Current EV powertrains are becoming increasingly more serviceable and as such, relay technologies need to evolve now more than ever. Technological limits are being pushed further and newer mechanical relays are now able to switch 450V with over 100 amps, allowing them to meet the present high powering requirements of fast charging, motor control, and extensive battery management systems.
   

Based on the propulsion, the electric vehicle relays market is divided into battery electric vehicles, plug-in hybrid electric vehicles, and hybrid electric vehicles. By 2034, the battery electric vehicle segment is expected to exceed USD 3 billion due to several key factors.
 

• Smart relays integrated with sensors and digital connectivity are advancing the ability to monitor the health of a relay in real-time as well as temperature and performance.
   
• In BEVs, these relays facilitate maintenance strategies such as prognosis to issues prior to failures, thus lowering the downtime and associated maintenance costs. Smart relays collect data that enhance the algorithms which manage the battery and the safety of the power system, supporting BEV component usage. These changes are in line with the trend of smart relay components in BEVs, which increase safety and efficiency.
   
• Given the focus on the longevity of the BEV, which encompasses a vehicle's lifecycle, there is now a major emphasis on relay durability. Their development includes aggressive current switching in duration and endurance to extreme conditions. Innovations include contact materials such as wear-resistant alloys, more comprehensive sealing, which adds to the relay’s life.
   
• Such developments work towards the reliability of the BEVs while at the same time improving the economy by decreasing the maintenance costs and satisfying users looking for heavy-duty electric automobiles.
   

In 2024, the China electric vehicle relays market dominating accounted for over 40% revenue share in the Asia Pacific. The Asia Pacific electric vehicle (EV) market is dominated by China, accounting for a market share greater than 40% in 2024.
 

• China is the leading region within the Asia Pacific market for EVs and has seen over 20% of new car sales within the region. This progressive EV relay market accelerates even more as manufacturers pursue dependable high-voltage relays compatible with electric drivetrains.
   
• Large volumes of relays as advanced EV components are much needed in China owing to the strong consumer base and government incentives along with infrastructural investments.
   
• Within Europe, electric vehicles' adoption is gaining momentum due to the strict emissions controls such as those in the EU aimed at minimizing CO2 emissions from new passenger vehicles. This unconventional approach is a strong incentive for the growth of the EV relay market. In an effort to comply with these rules, automotive manufacturers are raising their EV-related components such as relays procurement throughout Europe.
   
• As the largest U.S. electric vehicle manufacturer, Tesla is a leader in the charge emission relays market for EVs in this region, benefiting them through the volume of fabrications and technological solutions. The evolution of Tesla's relays has a direct impact on the entire supply chain of EVs in NA. Therefore, Tesla's market position and design changes to the EVs enormously impact the NA EV relay market.
