e-Axle Technology Trends

Patent application trends for Tesla and Huawei



  This report created by MarkLines focuses on a number of recent technical topics surrounding the automotive industry and is based on patent information from the “Technology Information Distribution Service - swimy” obtained by the Toyota Technical Development Corporation (TTDC). The two business areas of TTDC are intellectual property and measurement control solutions. The intellectual property (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.

  Technical trends of e-Axles, which integrate a transmission or differential gear (gearbox) with a motor, were investigated for this report based on patent information.

  The author selected two distinctive companies and examined their development trends, and confirmed the existence of a company that developed e-Axles around 2010 and has not developed since then, and a Chinese supplier that rapidly started development in 2020. In particular, it was confirmed that the trends of Chinese suppliers supported the content described in MarkLines' supplier information.
