The standard provides guidelines and specifications for the design, construction, and testing of WPT systems. It covers various aspects such as safety, performance, interoperability, and electromagnetic compatibility. Manufacturers and developers of WPT systems are required to comply with these standards to ensure the reliability and compatibility of their products.

One of the key elements of BS EN 61851 Part 22 is the communication protocol between the vehicle and the charging infrastructure. This protocol enables efficient power transfer, ensures safety during charging, and allows for authentication and control functionalities.

Benefits of BS EN 61851 Part 22

1. Convenience: Wireless charging eliminates the need for physical cables and connectors, making it more convenient for electric vehicle owners. Charging can be initiated simply by parking the vehicle over a designated charging pad.

2. Safety: The standard includes safety requirements to protect users from electrical hazards. It ensures that the charging system is properly grounded, has insulation measures, and can handle different environmental conditions.

3. Interoperability: BS EN 61851 Part 22 aims to establish interoperability between different WPT systems. This means that a vehicle equipped with a compatible receiver can charge on any charging pad that meets the standard, regardless of the manufacturer.

The Future of BS EN 61851 Part 22

As the adoption of electric vehicles continues to grow, the importance of standardization becomes evident. BS EN 61851 Part 22 sets a common framework that promotes the development and deployment of wireless charging infrastructure worldwide.

Furthermore, ongoing advancements in WPT technology are expected to improve efficiency, increase power transfer capabilities, and enhance overall user experience. The standard will continue to evolve alongside these technological developments to ensure seamless integration and increased adoption of wireless charging systems.
