Shangchi Motor Controller: Technological breakthroughs lead new changes in the industry

In the current wave of the automotive industry accelerating its transformation to new energy, the motor controller is one of the core components of electric vehicles, and its technological innovation is crucial to improving the performance and safety of the whole vehicle. Recently, Shangchi Motor Controller has made a series of major breakthroughs in technology research and development, which has attracted widespread attention from both inside and outside the industry. ​
According to information from the State Intellectual Property Office, a patent (publication number CN119938087A) applied by Shanghai Automotive Group Co., Ltd. entitled “Controller Upgrade Method, System, Equipment and Medium” provides reliable protection for the upgrade process of the motor controller. The uniqueness of this patent is that when the controller encounters an abnormal power outage or reset during the upgrade process, after it is powered on or reset again, it can accurately determine the current installation status of the upgrade file based on the current hash value, the benchmark hash value of the corresponding data segment in the benchmark file, and the target hash value of the corresponding data segment in the upgrade file, and continue to install the remaining data segments from the determined restart data segment without restarting the entire upgrade process. This innovation greatly improves the stability and convenience of motor controller upgrades, reduces the time waste and potential risks caused by upgrade abnormalities, and brings users a smoother user experience.

At the same time, the patent for “A safety state processing circuit for electric vehicle motor controller” (authorization announcement number CN115534689B) jointly obtained by Shanghai Automotive Electric Drive Co., Ltd., Shanghai Electric Drive Co., Ltd. and Shanghai Automotive Electric Drive Engineering Technology Research Center Co., Ltd. further demonstrates the excellent performance of Shangchi motor controller in safety performance. The safety state processing circuit involved in this patent can accurately monitor and effectively process the safety state of the motor controller under various complex working conditions, building a solid defense line for the safe operation of electric vehicles. ​
In terms of heat dissipation technology, the “assembly structure of a motor controller and an all-in-one IGBT tube heat dissipation” technology developed by Suzhou Yiqu Intelligent Technology Co., Ltd. provides an innovative solution to solve the problem of high power and difficult heat dissipation of the motor controller. This technology optimizes the installation process of the IGBT module, efficiently conducts the heat generated by the IGBT module when it is working to the aluminum substrate, and significantly improves the heat dissipation efficiency of the IGBT module. This not only helps to extend the service life of the IGBT module, but also effectively improves the overall stability and reliability of the motor controller, providing strong support for the performance of the motor controller under high-load operating environments.​
These technological breakthroughs of Shangchi Motor Controller not only lay a solid foundation for improving the competitiveness of its own products, but also inject new vitality into the technological development of the entire electric vehicle industry. With the gradual application and promotion of these innovative technologies, it is expected to promote the comprehensive improvement of electric vehicles in terms of performance, safety and user experience, and help the new energy vehicle industry move towards a more prosperous development stage.
