Summary
This report was prepared by MarkLines based on patent information from the "Technical Information Distribution Service - swimy" provided by Toyota Technical Development Corporation (TTDC), and reports on recent technology topics surrounding the auto industry. The two business areas of TTDC are intellectual property (IP) and measurement control solutions. The IP side of TTDC is involved in the collection and analysis of information on automotive technology developments globally, and provides services such as consulting for research planning, applying for patents in foreign languages, and technical translation.
The development of wireless charging is progressing in countries around the world, and it is expected that with this technology electric vehicles will become even more widespread. Therefore, this report will present the technology trends of this technical area and development items that are being developed based on patent information on wireless charging technology for electric vehicles.
The number of patent applications was increasing from 2020 to 2021, but a downward trend is seen in 2022. By technology field, stationary wireless charging is the most common, but there are also many patent applications for wireless charging while driving. Development items include high-precision position control and power supply systems that respond to abnormalities, contactless power supply and vehicle management systems, and heat generation countermeasure technology for wireless charging devices.
