The global electric vehicle relay market size was valued at USD 3.18 billion in 2022. The market is projected to grow from USD 5.34 billion in 2023 to USD 12.45 billion by 2030, exhibiting a CAGR of 16.6% during the forecast period.

An automotive relay is a digital or electromechanical managed switch designed for DC voltage in passenger consolation systems. Relay controls power levels in harsh environments. It works with electromagnetism, an electric-powered switch transforming small electric energy into large currents. The conversion occurs while an electrical current shifts on electromagnets to change the current circuits while operating functions in electric vehicles.

The number of relays in the vehicle depends on the features added to the electric vehicle. The market is set to witness significant growth in the upcoming years. This is due to increasing demand for electric vehicles, rise in technological developments, and the surging demand for advanced vehicle applications. Further, the increase in demand for safety features is expected to drive the market expansion during the forecast period.


Market Showed Signs of Recovery Post-COVID-19 Owing to Positive Steps from OEMs to Boost EV Adoption

The COVID-19 pandemic severely affected the automotive relay industry due to enforcement of lockdown restrictions across various countries.

The COVID-19 pandemic significantly impacted the market during 2020 and 2021. The pandemic harshly impacted the automotive, defense, and aerospace industries. The automobile industry was highly affected due to a sudden decline in the sales of all types of vehicles. However, the sales of electric vehicles, including battery and hybrid electric vehicles improved post-June 2020 as lockdowns were implemented in most countries. The declining sales of electric vehicles directly affected the EV relay market. During the pandemic, the demand for relays was high due to increasing sales of electric vehicles. The sales of electric vehicles (BEVs & HEVs) were mainly dominant during the post-pandemic period. The market growth is attributed to increasing technology and OEM’s launches of new EV models in the coming years.

Rising Demand for Higher Switching Capacity Relays for Electric and Hybrid Vehicles is a Prominent Trend

The electric vehicle relay manufacturers have been focusing on enhancing the efficiency and performance of their products. The companies are focused on reducing power losses, enhancing switching capabilities, increasing reliability, and extending the lifespan of relays to meet the demand for electric vehicles. The high-voltage DC components are essential for electric and hybrid vehicles. The HVDC relay is crucial in electric cars, trucks, vans, and buses. The pre-charge relay and the main contractors are part of the Battery Disconnect Unit (BDU), protecting the electronics and securing safety. These developments increase the global market size. Moreover, the demand for HVDC relays is anticipated to increase exponentially with the global trend of expansion of renewable energy. The relays are deployed across various applications in electric vehicles. These comprise battery management systems, HVAC, electric power steering, inverter control, safety systems, and others, which require an appropriate design for switching the relay on or off. Thus, the rising demand for higher switching capacity relays for electric and hybrid vehicles is expected to boost the electric vehicle relay market growth.


Increasing Adoption of Advanced Technology for Safety Concerns and Comfortable Vehicles to Boost Market Growth

The need for safer and more comfortable vehicles has been a longstanding concern in the automotive industry. Manufacturers continuously focus on addressing these requirements. This has increased the usage of relays in such electronic systems. The growth is attributed to the rising adoption of advanced technologies, such as ADAS, which delivers adaptive cruise control, lane-keeping assistance, automatic emergency braking, and blind-spot detection, which are becoming increasingly common in modern technologies. These systems enhance safety by assisting drivers and mitigating the risk of accidents.

For instance, in July 2023, MG Motor India revealed a new variant of its ZS electric vehicle. The new vehicle delivers new Autonomous Level-2; the system works at low, medium, and high levels of sensitivity and haptic, audio, and visual warning levels. The ADAS package includes Traffic Jam Assist (TJA), Forward Collision Warning (FCW), and Speed Assist System (SAS). The adoption of advanced technologies is directly proportional to the demand for relays. The increasing demand for such applications in upcoming electric vehicles and active developments for such advanced features will drive the growth of the market during the forecast period.


Inconsistency in Design and Limited Switching Capacity May Hamper the Market Growth

Lack of a standardized relay design can lead to compatibility issues. Various manufacturers may have variations in their relays' pin configurations, mounting arrangements, or terminal assignments. This can make it challenging to interchange relays from different manufacturers or even within the same vehicle model. It may require additional modification or adapters to fit a specific relay into an exciting system, which can increase complexity and potential errors during installation or replacement. Thus, the incompatibility of relays hampers the market growth.

Furthermore, lack of standardized designs can result in variations in relay characteristics such as coil voltage, contact ratings, contact materials, and switching times. This can lead to relay performance and behavior inconsistencies across different vehicles and applications. The lack of uniformity can make it difficult to compare or predict the relay's performance and suitability for specific requirements, potentially impacting reliability and system performance. Therefore, it has become difficult for relay manufacturers to develop standard relay designs. These factors may hinder the industry growth to some extent.
