Strategic Role of Relays Strengthens Across Electrified Drivetrains

Electric vehicle relays serve as critical switching and protection devices managing high-voltage circuits across traction motors, onboard chargers, and battery management systems. Their influence spans multiple automotive electronics segments, contributing:

8-10% of the global EV components market
6-7% of the battery management systems market
4-5% of the automotive safety & control systems market
2-3% of EV powertrain and drivetrain markets

As EVs evolve toward more compact, thermally efficient, and intelligent electronics, demand for high-performance relay systems-featuring enhanced arc suppression, isolation, and thermal durability-is accelerating.

Contactor Relays Lead Product Demand with 34% Market Share

The contactor relay segment-projected to secure 34% of revenue in 2025-will remain the dominant category due to its superior ability to manage high-voltage switching in EV powertrains. These relays ensure safe current flow during battery engagement, charging, and shut-off events. Their extensive integration in battery management systems, traction inverters, and fast-charging modules reinforces their market leadership.

The segment’s momentum is further supported by the shift toward modular EV platforms requiring compact, thermally robust, and arc-resistant relay architectures.

Passenger Vehicles to Capture 61% of 2025 Market Revenue

The passenger vehicles segment will account for 61% of the market in 2025, powered by accelerated production of electric cars worldwide. As passenger EV models integrate advanced infotainment, thermal management, and safety electronics, the need for reliable relay systems has intensified.

Global policy incentives, stricter fuel efficiency standards, and increasing affordability of electric passenger vehicles further contribute to segmental dominance.

BEVs to Maintain Largest Share with 66% Market Contribution

Battery electric vehicles (BEVs)-requiring a higher density of relays per unit-are set to dominate with 66% share in 2025. The shift toward fully electric powertrains, regulatory bans on internal combustion engine vehicles, and the scaling of high-capacity lithium-ion batteries continue to boost BEV production.

Growing integration of relays in regenerative braking, traction control, fast-charging, and battery protection circuits positions this segment at the forefront of long-term EV relay adoption.
