Automotive & EV EMC Testing

Automotive & EV EMC testing is performed to ensure the electromagnetic compatibility of electronic systems used in conventional, hybrid, and electric vehicles. Modern vehicles integrate a growing number of electronic subsystems, including engine control units (ECUs), battery management systems (BMS), onboard chargers, DC-DC converters, inverters, infotainment systems, telematics modules, radar sensors, and advanced driver-assistance systems (ADAS), all operating in proximity. EMC testing ensures that these systems function reliably without generating excessive electromagnetic emissions or being affected by external electromagnetic interference.

Testing typically includes radiated emissions, conducted emissions, radiated immunity, conducted immunity, electrostatic discharge (ESD), transient immunity, bulk current injection (BCI), and power line disturbance testing. These tests evaluate how the device under test (DUT) performs under electromagnetic disturbances commonly encountered in vehicle environments, including switching noise from power electronics, load dump events, RF exposure, and interference from onboard or nearby electronic systems.

Automotive EMC testing is commonly performed in accordance with standards such as CISPR 25, ISO 11452, ISO 7637, UNECE R10, and OEM-specific EMC requirements. These standards define test methods for measuring emissions and verifying immunity performance for automotive electronic components, EV powertrain systems, and vehicle-level assemblies.

Testing is conducted in specialized EMC facilities using equipment such as anechoic chambers, absorber-lined shielded enclosures, RF amplifiers, antennas, ESD simulators, transient generators, LISNs, and current injection probes. These controlled environments allow engineers to evaluate emissions, inject disturbances, and monitor system performance to ensure compliance with automotive EMC standards and reliable operation in real-world driving and charging conditions.
