TacSense Technology empowers the upgrading of new energy vehicles

This demo day event is a platform for Xiaomi to fully showcase its industry chain partners, realize business collaboration and cooperation of Xiaomi industry chain companies through the platform, and display and dock potential partners, hoping to continue to create long-term strategic and wealth value for Xiaomi industry chain enterprises, and jointly strive to use technology to make our lives better.

The theme of the event was automotive electronics, and the heads of Xiaomi Auto and business partners in the industry chain 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 been deeply involved in the force dimension monitoring of the whole power battery industry chain such as battery cell manufacturers, vehicle manufacturers, testing institutions and universities, and has accumulated rich experience in application scenarios and production and testing data.

In this demo day event, TacSense Technology successfully exhibited the TAS pressure distribution measurement system for real-time monitoring of power battery expansion force. Wang Xiaoyang, CEO of TacSense Technology, introduced the application of TAS pressure distribution measurement system in the expansion force monitoring of the whole life cycle of power batteries to Lei Jun, founder, chairman and CEO of Xiaomi Group, and senior managers of Xiaomi. Partners in the automotive electronics industry chain affirm that TacSense Technology is in the right direction to improve the safety of power batteries. Chen Xu, Industrial Sales Director of TacSense Technology, and a number of industry-leading power battery companies had full exchanges at the 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 Academician Ouyang Minggao, a power battery expert from Tsinghua University, 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 in this project show that there is a strong correlation between battery expansion force and battery safety. Professor Lu Languang, the main leader of the team, said that in the process of battery charging and discharging, the TAS pressure distribution measurement system of TacSense Technology is used to intervene in the expansion force monitoring of the whole life cycle of the battery, which can effectively judge the aging degree of the battery and infer the internal lithium separation state, and carry out safety early warning through the force dimension before the battery fails or causes safety risks, so as to ensure that the algorithm can warn the battery explosion and fire risk earlier and protect the safety of users. In addition, the big data research based on the force dimension will also provide new data dimensions for the BMS algorithm, such as the real-time adjustment of the charging current according to the expansion force during the fast charging process, so as to ensure battery safety and protect battery life while improving charging efficiency.
