　　TacSense Technology | Enabling the Upgrade of New Energy Vehicles
　　This demo day event is a platform for Xiaomi to fully display its industry chain partners. Through this platform, the business collaboration and cooperation of Xiaomi industry chain companies will be realized, and potential partners will be displayed and connected, hoping to continue to create long-term development for Xiaomi industry chain enterprises. Strategy and wealth value, working together to make our lives better with technology.
　　The theme of this event is automotive electronics. The person in charge of Xiaomi Auto and business partners in the industry chain have mentioned the importance of power battery safety in the three-electric system of electric vehicles. In order to improve the safety of power batteries, TacSense Technology has increased R&D investment in response to the needs of power battery expansion force detection, and invested a lot of engineering resources to support customers in product applications. At present, TacSense Technology has deeply participated in the force dimension monitoring of the entire power battery industry chain such as battery cell manufacturers, OEMs, testing institutions and universities, and has accumulated rich experience in application scenarios and production testing data.
　　In this demo day event, TacSense Technology successfully exhibited the TAS pressure distribution measurement system applied to real-time monitoring of power battery expansion force. TacSense Technology CEO Wang Xiaoyang introduced the application of the TAS pressure distribution measurement system in the expansion force monitoring of the power battery throughout the life cycle to Lei Jun, the founder, chairman and CEO of Xiaomi Group, and senior managers of Xiaomi. The partners of the automotive electronics industry chain affirm that TacSense Technology is in the right direction in improving the safety of power batteries. Chen Xu, the industrial sales director of TacSense Technology, and a number of industry-leading power battery companies had full exchanges at this event and gained positive business cooperation.

　　Power Battery Safety | Background Introduction
　　With the reports of major fire accidents caused by battery safety in various places, battery safety issues have received more and more attention. In September 2021, TacSense Technology and the intelligent battery sensor research team of Tsinghua University power battery expert Ouyang Minggao academician team had a full exchange on the application of TacSense Technology's TAS pressure distribution measurement system in power battery safety. Multiple sets of experimental data on this subject show that the battery expansion force has a strong correlation with battery safety. Professor Lu Languang, the main leader of the team, said that during the charging and discharging process of the battery, using the TAS pressure distribution measurement system of TacSense Technology to intervene in the expansion force monitoring of the battery life cycle can effectively judge the aging degree of the battery and infer the internal lithium precipitation state. Before the battery fails or a safety risk occurs, a safety warning is carried out through the force dimension, so as to ensure that the algorithm can warn the battery explosion and fire risk earlier and protect the life safety of the user. In addition, the big data research based on the force dimension will also provide a new data dimension for the BMS algorithm. For example, the charging current can be adjusted in real time according to the expansion force during the fast charging process, which can improve the charging efficiency while ensuring battery safety and protecting battery life.
