세계의 자동차용 릴레이 시장 예측(-2032년) : 유형별, 차량 유형별, 전압별, 접점 구성별, 용도별, 지역별 분석

According to Stratistics MRC, the Global Automotive Relay Market is accounted for $16.11 billion in 2025 and is expected to reach $25.09 billion by 2032 growing at a CAGR of 6.53% during the forecast period. An automotive relay is an electromechanical or solid-state switching device used in vehicles to control high-current circuits with a low-current signal. It acts as an intermediary between the vehicle's control system, like switches or electronic control units (ECUs), and components such as headlights, fuel pumps, cooling fans, and starter motors. By using a small control current to operate the relay, it prevents heavy current from passing through delicate switches, enhancing safety and reliability. Automotive relays improve energy efficiency, reduce wiring complexity, and protect electrical components from overheating or damage, playing a critical role in modern vehicle electrical systems.

According to the International Energy Agency, new electric car registrations in the U.S. reached 1.4 million in 2023, marking a growth of over 40% from 2022.
