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. The global rise in electric vehicle (EV) adoption is driving the market. Government initiatives for zero-emission vehicles and increased consumer awareness of environmental sustainability have significantly boosted EV sales.
 

Electric Vehicle Relays Market

For instance, in 2023, electric car sales increased by 3.5 million units, reflecting a 35% year-on-year growth. The market saw over 250,000 new registrations weekly. Electric vehicles represented 18% of total car sales in 2023, up from 14% in 2022. Key markets like China, Europe, and North America have implemented strict emission standards and incentives for EV purchases. This shift has created a direct demand for EV-specific components, including high-voltage relays, as each EV requires multiple relays for safety and operational functions.
 

Stringent safety regulations in the automotive industry, particularly for EVs, are increasing the demand for high-quality relays. Organizations such as ISO and SAE have set specific standards for EV components, including electrical safety requirements. These regulations mandate the use of certified high-voltage relays to ensure proper isolation between high-voltage and low-voltage systems, protect against short circuits, and enable emergency power cut-off capabilities. Manufacturers must comply with these standards, driving consistent demand for advanced relay systems.
 

Electric Vehicle Relays Market Trends

The shift to higher voltage systems (800V and beyond) in EVs is driving demand for specialized relay solutions. Manufacturers are investing in R&D to develop relays that can handle these increased voltage levels safely. This trend is particularly prominent in premium EVs and commercial vehicles, where faster charging and improved performance are key priorities.
 

For instance, in June 2024, Pickering Electronics has showcased its range of high voltage (HV) reed relays in India EV Show 2024. Featured products include the Series 219 surface mount reed relay and the 5kV version of the single-in-line Series 104 reed relay. Additionally, Pickering will highlight other HV models, such as the Series 67 and 68 families, which utilize former-less coils for a compact size of 58.4 x 12.6 x 14.5mm.
 

As EVs become more compact, the demand to reduce the size and weight of electronic components intensifies, without sacrificing functionality or durability. Designers must innovate with miniaturized parts, efficient packaging, and advanced integration techniques to incorporate high-power switching capabilities into increasingly limited vehicle architecture spaces.
 

Electric Vehicle Relays Market Analysis

Electric Vehicle Relays Market Size, By Product, 2022-2034 (USD Billion)

Based on the product, the 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 demanding conditions of electric vehicles (EVs) such as high voltages, extreme temperatures, and constant vibrations necessitate mechanical relays that meet stringent reliability and lifecycle standards. Manufacturers are utilizing advanced materials, precision engineering, and rigorous testing to develop relays capable of withstanding over 1 million switching cycles, ensuring safety and performance throughout the vehicle's lifespan.
 

For instance, in May 2024, Japan-based FCL Components launched the FTR-E1-HC, a lightweight, high-voltage switching relay designed for automotive and power applications. The FTR-E1-HC features no specific polarity requirements for load terminal connections and consumes only 1.2 W at rated coil voltage. This design eliminates the need for a holding voltage coil drive circuit, reducing both costs and space requirements.
 

As EV powertrains become more powerful, relay technology must keep pace, handling higher voltages and currents. New mechanical relay designs now offer switching capacities of 450V and 100A or more, meeting the increasing electrical demands of fast charging, motor control, and battery management systems.
 

Electric Vehicle Relays Market Share, By Propulsion, 2024

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 with embedded sensors and digital connectivity are revolutionizing real-time monitoring of relay health, temperature, and performance.
 

In BEVs, these relays enable predictive maintenance by identifying potential issues before failures occur, reducing downtime and maintenance costs. By collecting data, they support predictive analytics, enhancing battery management and power system safety. These smart relays align with the trend of connected components in BEVs, promoting improved safety and efficiency.
 

As BEVs are designed for long lifespans, there is a growing focus on relay durability to match the vehicle's lifecycle. New relays are being developed to withstand frequent high-current switching and last longer under challenging conditions. Innovations in contact materials, such as wear-resistant alloys, and improved sealing mechanisms are extending relay life. This trend supports BEV reliability and reduces maintenance costs, benefiting both automakers and consumers seeking durable electric vehicles.
 

China Electric Vehicle Relays Market, 2022 – 2034, (USD Million)

China electric vehicle relays market accounted for 40% of the revenue share in 2024. China, the world's largest electric vehicle (EV) market, sees EVs making up over 20% of new car sales. This rapid adoption drives the market as automakers seek reliable high-voltage relay solutions for electric drivetrains. Strong consumer demand, government incentives, and infrastructure investments in China are fueling the need for advanced EV components like relays.
 

In Europe, stringent emissions regulations, such as the EU's CO2 reduction targets for new passenger cars, are accelerating the shift to electric vehicles. This regulatory environment is a key growth driver for the EV relay market. Automakers striving to meet these standards are increasing their demand for EV components, including relays, across Europe.
 

As North America's leading EV manufacturer, Tesla significantly impacts the regional EV relay market with its technological advancements and manufacturing scale. Suppliers must keep up with Tesla's evolving relay requirements. Tesla's market dominance and continuous innovation in EV design heavily influence the overall North American market.
