BMW GS 95002-3:2015

Electromagnetic Compatibility (EMC) Requirements and tests on components above 60 V nominal voltage

BMW GS 95002-3:2015 is a specialized standard outlining Electromagnetic Compatibility (EMC) requirements and test procedures for automotive components that operate at a nominal voltage exceeding 60 V. Developed by BMW for its in-house and supplier use, this document ensures that high-voltage (HV) systems within vehicles meet stringent EMC criteria, maintaining reliable performance and minimizing interference with other on-board or external systems.

Key aspects of BMW GS 95002-3:2015 include:

1. Scope and Applicability

   • Focuses on the above 60 V subsystem environment in electrified, hybrid, or other specialized vehicle architectures.
   • Provides requirements for both conducted and radiated emissions and immunity, preventing disruption to or from auxiliary systems like on-board electronics, infotainment, sensors, and more.

2. Test Conditions and Levels

   • Specifies frequency ranges, waveforms, and amplitudes to be used in validating emissions control and susceptibility.
   • Details test setups (e.g., bench-based or vehicle-level) and measurement methodologies necessary to achieve repeatable and consistent results.

3. Critical Safety Considerations

   • Addresses HV component safety due to elevated voltage levels, integrating measures for isolation, grounding, shielding, and protective circuitry to guard both the component and the surrounding environment from unintended interference or electric shock risks.

4. Performance Metrics

   • Requires that devices demonstrate continuous, reliable operation during and after exposure to prescribed EMC stress conditions.
   • Defines acceptance criteria for performance under transient or surge conditions, ensuring robust behavior over the component’s operational life cycle.

5. Documentation and Compliance

   • Mandates thorough test plans, procedures, and reports, ensuring traceability and proof of compliance for BMW’s internal verification processes.
   • Often used alongside industry-recognized EMC standards to align BMW’s vehicle systems with globally accepted automotive and regulatory requirements.

By meeting BMW GS 95002-3:2015, suppliers and engineers confirm that their high-voltage components integrate seamlessly and safely into BMW’s electrical architecture. This ensures minimal electromagnetic interference, reliable powertrain operation, and a consistent customer experience—key factors in the success and trustworthiness of BMW’s advanced vehicle platforms.
