IEC PAS 61980-5:2024 PDF

Overview - IEC PAS 61980-5:2024 (D-WPT for EVs)

IEC PAS 61980-5:2024 defines interoperability and safety requirements for dynamic wireless power transfer (D-WPT) systems that deliver energy to electric road vehicles via magnetic field (MF‑D‑WPT) while vehicles are in motion. The document applies to off‑board supply equipment designed to charge the RESS (rechargeable energy storage system) and/or other on‑board electrical systems, operating at supply voltage ratings per IEC 60038 (up to 1 000 V AC and up to 1 500 V DC). It is intended for systems interoperable with EV devices meeting ISO 5474‑4 and ISO 5474‑6.

Key topics and technical requirements

• System scope and classification
  • Compatibility classes and installation types for MF‑D‑WPT.
• General supply device requirements
  • Architecture of off‑board equipment and required power transfer behavior.
  • Input voltage and kVA levels, and output power (including conditions when stationary).
• Power transfer characteristics
  • Requirements for dynamic power transfer phases, alignment, and how speed of travel affects transfer.
  • Methods for measuring efficiency in D‑WPT (dynamic measurement procedures are specified).
• Frequency and EMC
  • Frequency requirements and electromagnetic compatibility (EMC) provisions to limit interference and ensure reliable operation.
• Safety and protection
  • Electrical safety, protection against electric shock, heating effects of foreign objects, constructional strength, and marking/instructions.
• Communication and interoperability
  • Requirements for control/communication between off‑board supply and vehicle for secure, interoperable charging.
• Test, service and installation
  • Procedures and test conditions; annexes provide reference EV power and coil configurations for verification.
• Informative annexes
  • Annexes A–D include reference EVPCs, multi‑phase and transversal coil topologies, magnetic field distributions, and mechanical/electrical schematics useful for testing and design.

Practical applications and users

IEC PAS 61980‑5 is practical for:

• EV infrastructure designers and roadway integrators implementing dynamic wireless charging lanes.
• EV manufacturers and power electronics suppliers ensuring interoperability with off‑board D‑WPT systems.
• Utilities and transport authorities planning large‑scale electric road infrastructure.
• Test laboratories and certification bodies validating safety, EMC, and performance of MF‑D‑WPT installations.
• Regulators, city planners, and system integrators evaluating standards compliance for public deployments.

Related standards

• IEC 60038 (standard supply voltage ratings)
• ISO 5474‑4 and ISO 5474‑6 (vehicle-side device compatibility)
• Other parts of IEC 61980 series (WPT system family)
