Normas de EMC

Electromagnetic compatibility (EMC) standards define maximum allowable emissions and minimum required immunity for electronic equipment operating in shared electromagnetic environments. SiCore dock and receiver products must satisfy regional frameworks — EU EMC Directive via harmonized EN standards, FCC Part 15 and Part 18 in North America, and customer-specific industrial requirements from automotive and intralogistics OEMs. Wireless power at industrial power levels often falls outside consumer WPT convenience categories; classification as industrial equipment, power conversion apparatus, or dedicated charging infrastructure determines applicable limit tables.

Standards distinguish ports: AC mains input, DC output to vehicle battery, signal/control ports (CAN, Ethernet, IO), and enclosure radiated emissions. A floor-flush dock presents mains-conducted limits on the facility side and may require separate evaluation of radiated emissions from the pad surface and pit cavity. AGV receivers evaluate battery-port conducted emission and vehicle-mounted radiated profiles with the charging coil energized under representative alignment.

01Key standard families

• EN 61000-6-x: generic EMC immunity and emission for residential, commercial, and industrial environments — 6-2 emission, 6-4 industrial immunity common baselines.
• CISPR 11 / EN 55011: industrial, scientific, and medical equipment — group and class selection for high-power conversion products.
• CISPR 32 / EN 55032: multimedia and general ITE emission limits where control electronics dominate the spectral profile.
• IEC 61980 series: WPT for EV and industrial systems — alignment, interoperability, and EMC-relevant operating conditions.
• Automotive OEM specs (e.g., ISO 11452 derivatives, manufacturer EMC sheets): additional limits for AGV receivers integrated into customer vehicles.

02Classification and limit selection

Group 1 equipment uses RF energy internally without intentional radiation; Group 2 includes ISM and WPT systems with intentional radiated fields — limit tables and measurement distances differ. Class A permits higher emission for industrial non-residential use; Class B applies where residential proximity exists — rare for warehouse docks but relevant for pilot installations in mixed-use campuses. SiCore documents group/class selection per SKU with rationale tied to intended deployment environment and maximum operating power.

Harmonized standards under the EU EMC Directive require a Declaration of Conformity supported by technical documentation, risk analysis of foreseeable EM environments, and test evidence. North American certification paths may combine FCC equipment authorization with OSHA and NEC facility requirements — EMC is necessary but not sufficient for site acceptance.

03Test planning and documentation

SiCore EMC test plans define worst-case operating modes before chamber time: maximum charge power, worst alignment within spec, simultaneous CAN telemetry, and multi-pad crosstalk where applicable. Mode selection is justified in the technical file — regulators and OEM auditors reject 'best-case' operating points. Pre-scan reports from accredited or internal semi-anechoic facilities gate layout freeze; final compliance tests use identical firmware, filter BOM, and cable harness part numbers as production.
