The demand for advanced safety and comfort features in modern automobiles, such as ADAS (Advance Driver Assistance System), infotainment systems, and HVAC (Heating, Ventilation, and Air Conditioning) systems, is increasing. Relays are essential for managing a vehicle's electrical systems, and as more people opt for these cutting-edge technologies, the demand for relays is anticipated to increase.

  • For instance, LG Magna e-Powertrain has announced the launch of its latest manufacturing plant in Ramos Arizpe, Mexico. The facility will specialize in producing inverters, motors, and onboard chargers, with the primary aim of supporting General Motors' electric vehicle (EV) manufacturing operations.

The market for automotive relays is anticipated to grow as autonomous vehicle use rises. Relays are important for managing the intricate network of electrical systems that autonomous vehicles require to operate. The need for automotive relays is anticipated to surge dramatically along with the demand for autonomous vehicles.

COVID-19 has significantly impacted the automotive relay market. Governments worldwide implemented strict import-export bans on raw materials used in the manufacturing of automotive components for a substantial portion of the pandemic year. This sudden restriction led to a sudden decrease in the availability of essential raw materials for automotive relays. The COVID-19 pandemic had a severe impact on aviation production and sales, causing detrimental effects on the automotive relay market. This, in turn, resulted in significant disruptions to supply chains and production schedules. Global governments imposed rigorous lockdowns and mandated social distancing measures to curb the spread of the virus. Thus, the automotive relay market is anticipated to experience rapid growth in the coming years.

Relays in electric automotive components require unique features for each one to meet Electric Control Unit (ECU) requirements. Advancements in miniaturization and high contact capability are essential to overcome space constraints. Highly reliable relays are essential for safety assurance. Components with attributes like latching, low noise, and ultra-miniaturization are necessary for advanced switching technology in vehicles.

Industry Dynamics

Growth Drivers

  • Growing demand of hybrid and electrical vehicles will drive the growth of the market

The market growth of automotive relay is primarily driven by the increasing demand of hybrid and electric vehicles. The rise in components used in electric vehicles has led to a higher demand for relays that are designed for switching purposes. Each relay must have unique characteristics that are tailored to its specific needs. Advancements in technology are especially necessary to achieve high contact capacity and miniaturization, particularly in the Electric Control Unit (ECU), where a cluster of relays limits the available mounting space. Reliability is paramount for safety reasons. As the need for switching technology to accommodate the latest electrical functions in vehicles increases, components that feature characteristics like low noise, ultra-miniaturization, and latching have become more popular.

More relays are anticipated to be fitted per car due to the increased use of electronic equipment and emphasis on safety. Additional relays are required for auxiliary devices. Advancements in PCB relays are anticipated to boost market growth by reducing vehicle weight and enhancing fuel economy.

The automotive relay market has experienced substantial growth due to the increasing demand for luxury vehicles, the rising adoption of electric vehicles, and the growing penetration of automotive safety technologies. This growth can be attributed to the increasing use of electronic components in vehicles and the preference of consumers for electronic relays over electromagnetic relays.
