The Wireless Power Consortium (WPC) has presented Qi 2.1, a significant further development of the wireless charging standard. A key feature of this version is the integration of a movable charging coil that automatically aligns itself optimally with the device. This innovation promises more efficient charging processes and expands the range of applications, particularly in the automotive sector.
Highlights
- Automatic alignment of the charging coil for higher charging efficiency.
- Improved compatibility with various smartphone sizes and models.
- Particularly advantageous for use in vehicles.
Technical innovations of Qi 2.1
The Qi charging standard has established itself as the market leader in the field of wireless charging options. It is not only used for conventional wireless chargers. Manufacturers in the automotive industry also rely on the convenient charging option in the driver’s cockpit. Qi 2.1 is now the latest update, as reported by 9to5google and others. The movable charging coil in particular is a real highlight.
The technology developed by Panasonic makes it possible to move the charging coil in the charger using a motor and automatically align it with the charging coil integrated in the smartphone. An electrical detection grid identifies the position of the smartphone so that the charging coil can be adjusted accordingly. This precise alignment minimizes energy loss and shortens charging times.
Possible applications in the automotive sector
The integration of Qi 2.1 in vehicles offers considerable advantages. Drivers can simply place their smartphone in the charging cradle without having to worry about exact positioning. The movable charging coil adjusts automatically, allowing the device to be charged safely and efficiently even when the vehicle is moving.
If the concept works, this will not only prevent frustration. After all, it is annoying if the smartphone is not charged after an hour-long journey due to an incorrect position in the charging cradle. It also increases comfort and safety, as there are no distractions caused by manual adjustments.
Compatibility and future prospects
Although the Qi2 standard is already supported by some manufacturers such as Apple, its distribution is still limited. The introduction of Qi 2.1 could accelerate acceptance as the technology improves compatibility with a wide range of smartphone models.
This is particularly relevant in the automotive sector, where different user devices need to be taken into account. However, there is currently no concrete information on when the first vehicles will be equipped with this technology.
Conclusion
Qi 2.1 represents a significant advance in the field of wireless charging. The motorized, movable charging coil enables optimal alignment with the smartphone, which increases charging efficiency and convenience for users. This technology offers promising potential applications in the automotive sector in particular. It remains to be seen when and in which vehicle models Qi 2.1 will be used for the first time.
