자동차용 릴레이 시장 : 시장 기회, 성장 촉진요인, 산업 동향 분석, 예측(2025-2034년)

The Global Automotive Relay Market reached USD 16.8 billion in 2024 and is projected to expand at a CAGR of 6.2% between 2025 and 2034. Rising global vehicle production is a major driver, as automakers integrate numerous relays into new vehicles to support critical functions. The demand for advanced electronic systems in passenger and commercial vehicles continues to increase, driving the need for efficient relays. Modern automobiles rely on relays for power distribution, lighting, climate control, infotainment, and safety systems, fueling the market's expansion. Additionally, the growing adoption of electric vehicles is shaping industry trends, as EVs require high-performance relays for battery management, motor control, and power distribution. Unlike traditional vehicles, EVs depend on high-voltage relays for safe and efficient operation, further stimulating market growth.

The market is categorized by vehicle type, with the passenger vehicle segment dominating in 2024, generating USD 12.4 billion. This segment is expected to grow at a CAGR of 6.6% throughout the forecast period. The increasing demand for comfort, safety, and advanced connectivity features in passenger cars is driving relay adoption. Consumers expect seamless operation of power windows, lighting systems, powertrain controls, and ADAS features, leading manufacturers to integrate more relays. Urbanization and rising disposable incomes in developing regions further support passenger vehicle sales, creating additional demand for automotive relays.

Segmented by propulsion type, the market includes internal combustion engine (ICE) and electric vehicles. In 2024, ICE vehicles accounted for 77% of market share. However, the EV segment is anticipated to expand at a CAGR of over 7.2% from 2025 to 2034. Gasoline- and diesel-powered vehicles require relays for engine management, HVAC systems, fuel control, and lighting functions. Despite this, the EV sector is experiencing substantial growth fueled by government incentives, strict emissions policies, and advancements in battery technology. These vehicles require high-voltage relays for battery management, charging, and power control, further driving market demand.

Based on application, automotive relays are classified into powertrain systems, body and comfort systems, safety and security systems, infotainment and connectivity, and battery management and charging systems. The body and comfort systems segment is expected to lead as automakers continue integrating electronic components for enhanced passenger convenience. Relays enable automated control of power windows, central locking, seat adjustments, sunroofs, and climate regulation. The luxury vehicle market's expansion, coupled with demand for high-end electronics, is accelerating relay usage in this category. Additionally, regulatory mandates for safety features such as automatic wipers, heated mirrors, and anti-pinch window mechanisms contribute to the increasing adoption of relays.

Geographically, the Asia Pacific region accounted for 45% of the market's revenue share in 2024. The region's strong vehicle production industry, along with increasing demand for high-voltage relays in electric and hybrid models, is boosting market growth. China, a key contributor, generated USD 3.41 billion in revenue, driven by the rapid expansion of its EV sector and high-volume automotive manufacturing.
