The global electric vehicle (EV) revolution isn’t just about batteries, motors, and sleek new designs—it’s also about the hidden components making it all possible. One such hero is the humble relay, a critical device that manages high-voltage circuits inside electric cars, ensuring safe and reliable power distribution.
According to the latest industry outlook, the Electric Vehicle Relays Market is on track to soar from USD 3.7 billion in 2025 to USD 8.3 billion by 2035, growing at a compound annual growth rate (CAGR) of 8.4%. This rapid growth mirrors the surging demand for EVs worldwide, driven by stricter emission regulations, improved charging infrastructure, and the global shift toward sustainable mobility.
A Decade of Strong Growth Ahead
Between 2025 and 2030, the market is set to expand from USD 3.7 billion to USD 5.5 billion, adding nearly USD 1.8 billion in value. This early phase of growth will be fueled by the rising penetration of battery electric vehicles (BEVs) and hybrids, particularly across Asia-Pacific and Europe, where zero-emission mandates are gathering pace.
From 2030 to 2035, the market will accelerate further, climbing to USD 8.3 billion. Analysts expect stronger adoption of solid-state relays and thermal management solutions as vehicles increasingly shift to 800V and higher battery systems, enabling ultra-fast charging.
Why Relays Matter in the EV Boom
Think of relays as the traffic police inside an EV’s electrical highway. They direct current safely, protect against overloads, and isolate circuits when faults occur. With EVs operating at voltages of 400V to 800V—or even higher—reliability is non-negotiable.
Relays play crucial roles in:
- Battery Management Systems (BMS) – ensuring safe charging, discharging, and thermal protection.
- Drive Systems – managing high current for traction motors.
- Charging Infrastructure – supporting fast and ultra-fast charging.
- Safety Features – enabling emergency disconnect and interlock functions.
Key Segments Driving Growth
- By Product
The contactor relay segment is expected to dominate in 2025, commanding 34% of market revenue. Known for handling high current loads with mechanical isolation, these relays are indispensable for battery safety and protection during surges. - By Vehicle
Passenger cars will lead the way, capturing 61% of the market share in 2025. With consumer appetite for electric sedans, SUVs, and crossovers surging, automakers are integrating compact, noise-free relays to enhance driving experience. - By Propulsion
Battery electric vehicles (BEVs) will be the biggest contributors, holding a 66% share in 2025. Unlike hybrids, BEVs rely entirely on electronic systems, meaning they use more relays per vehicle.
