Overview
IEC PAS 61980-6:2025 defines communication and activity requirements for magnetic field dynamic wireless power transfer (MF-D-WPT) systems used to charge electric vehicles (EVs) while in motion. This Publicly Available Specification focuses on the operational and functional characteristics of MF‑D‑WPT communications and the associated positioning system needed to enable safe, interoperable dynamic wireless charging. It is intended to be applied together with IEC PAS 61980-5 and ISO 5474-6, ensuring supply devices and EV devices interoperate according to shared protocols and procedures.
Key topics and technical requirements
- Communication architecture and procedures: message sequences and state transitions for session setup, service request, compatibility checks, authentication, pairing, and termination.
- Power management signalling: unidirectional and bidirectional wireless signalling (including P2PS - point-to-point signalling) for negotiating and controlling power delivery.
- Positioning and alignment checks: functional requirements for lateral alignment, magnetic coupling verification, and positioning system interactions necessary for continuous dynamic charging.
- Power transfer operations: definitions for power transfer start/stop, inter‑inverter segment switching, stand-by and active power states, and controlled power transfer trajectories.
- Safety monitoring and diagnostics: ongoing monitoring, exception handling, wake‑up after power outage, and safety state transitions to protect vehicle and infrastructure.
- System architecture and components: informative annexes on supply-device to primary-device configurations, P2PS sensors, communication layers (vehicle ↔ supply ↔ cloud), segment switching strategies and use cases.
- State diagrams and sequences: comprehensive state models for supply devices (D‑SECC) and EV devices (D‑EVCC) to standardize behavior during dynamic sessions.
Applications and who should use this standard
IEC PAS 61980-6 is practical for organizations involved in:
- EV OEMs and power electronics designers developing onboard EV communication/control units for dynamic charging.
- Infrastructure providers and operators deploying MF‑D‑WPT lanes, primary coils, and segment control systems.
- Wireless charging system suppliers implementing P2PS, positioning sensors, and inter‑inverter switching.
- Testing and certification bodies validating interoperability, safety monitoring and communication protocols.
- City planners, transport authorities and utilities evaluating dynamic charging deployment scenarios and integration with grid/cloud management.
Use cases include highway or urban dynamic charging corridors, bus rapid transit charging, and pilot deployments where vehicles receive power while moving.
