Abstract: the new energy vehicle BMS thermal protection sensor research and development project team of Kemin sensor Innovation Research Institute has developed a low-cost, high-sensitivity and high reliability integrated high-voltage wire and temperature sensor failure prevention sensor module, which can better meet the requirements of high sensitivity and high reliability of the three-element battery thermal protection system widely used in New energy vehicles.

Recently, the first highly sensitive integrated sensor module used in new energy vehicle batteries and energy storage batteries in China was successfully developed in Shenzhen Kemin Innovation Research Institute. On August 2, 2018, in order to strengthen the research and development of new energy vehicle BMS thermal protection system and energy storage battery esbms thermal protection system sensors, the unveiling ceremony of Shenzhen Kemin sensor Co., Ltd. (hereinafter referred to as "Kemin sensor") and Shanghai Jiaotong University and South University of science and technology sensor joint innovation research institute was held in Kemin sensor Science Park.

Kong Weiting, chairman of Kemin sensing, said that it is of far-reaching significance for schools and enterprises to establish a joint innovation research institute. In the future, Kemin, Shanghai Jiaotong University and South University of science and technology will carry out comprehensive cooperation in industry, University and research in the fields of talent training, technology research and project development, make full use of the high-quality resources of universities and scientific and technological innovation enterprises, develop in-depth integration in talent training and scientific and technological research and development, and jointly create a new energy vehicle The high-tech R & D platform for sensors in energy storage batteries and Internet of things will provide strong talent support and technical support for the R & D of sensors in new energy vehicles, energy storage batteries and Internet of things in the country and Guangdong Province in the future.

According to the latest understanding, the new energy vehicle BMS thermal protection sensor research and development project team of Kemin sensor Innovation Research Institute has developed a low-cost, high-sensitivity and high reliability integrated high-voltage wire and temperature sensitive anti failure sensor module, which better meets the requirements of the three-element battery thermal protection system that is widely used in new energy vehicles for high sensitivity and high reliability, At the same time, the anti failure sensor module detects the heating temperature characteristics of the battery more accurately and timely, providing more accurate and timely thermal protection control information for the high-capacity ternary battery thermal protection control system. Kong Weiting introduced that this product is already in the reliability test stage. Before the end of the year, Kemin sensor will fully introduce this product to the market.

As a national high-tech manufacturer of temperature sensors and thermistors with independent intellectual property rights in China, after more than ten years of development, Kemin sensor has successfully shifted from home appliance sensor production to comprehensive industrial sensor production. At present, it has become the largest temperature sensor supplier of new energy vehicle battery thermal management system in China.

At present, the company has more than 40 national patented technologies, and has become a fixed point supporting provider for well-known enterprises such as Shenzhen BYD, BAIC, SAIC times, Wanxiang Group, Jinlong bus, Yutong Bus, Shenlong bus, Jianghuai Automobile, Zhongtai automobile and BIC battery, Tianjin Lishen and Guangyu group.
