Overview
IEC 62827-3:2016 - Wireless power transfer – Management – Part 3: Multiple source control management (IEC) defines methods and procedures for coordinating multiple wireless power sources in a spatial wireless power-transfer system based on magnetic resonance technology. The standard focuses on forming groups of power sources (WPMS-S networks) and managing power delivery to multiple receiving devices (WPMS-D) to achieve efficient, reliable spatial wireless power transfer.
Key topics and technical requirements
- Group formation and topology: Procedures to form and manage groups of power sources (WPMS-S and WPMS-SN) that communicate over wired or wireless networks to cooperate in a shared spatial area.
- Power transfer condition setting and sharing: Methods to set, share and control wireless power transmitting conditions (e.g., power level, phase) across multiple sources to optimize delivery to receiving devices.
- Device identification and authentication: Requirements and procedures for identifying and authenticating WPMS-Ds before initiating power transfer.
- Position detection and power mapping: Procedures for detecting WPMS-D positions in the spatial zone and mapping power-transfer areas and communication areas to manage coverage and efficiency.
- Wireless power distribution and synchronization: Guidelines for distributing power among multiple sources and synchronizing magnetic fields (magnetic resonance coupling) across sources to prevent interference and improve efficiency.
- Control messaging and states: Defined message types and interaction sequences for negotiation, notification, suspension, resumption, and termination of power transfer between WPMS-S and WPMS-D.
- Reconfiguration and fault handling: Processes to handle dynamic events such as appearance/disappearance of sources or devices, completion/resumption of charging, flat-battery scenarios, and orderly termination of power transfer.
- Interoperability and management functions: Overall model for a wireless power management system, including required functionalities for cooperative control.
Practical applications and users
IEC 62827-3 is intended for organizations and professionals designing, deploying, or testing spatial wireless charging and management systems, particularly those using magnetic resonance:
- Device manufacturers (audio, video and multimedia equipment noted in the standard)
- OEMs and system integrators building multi-coil or multi-transmitter wireless charging platforms
- Smart home, office and public-charging solution providers deploying spatial wireless power for multiple devices
- Standards engineers, test labs and certification bodies validating interoperability, safety and management behavior
- Network and control-software developers implementing WPMS messaging and synchronization logic
Implementing IEC 62827-3 helps ensure coordinated, efficient wireless power distribution in environments where multiple power sources and multiple receivers operate simultaneously.
