The 2rd “Lithium-ion Battery Thermal Test Theme Seminar” and New Product Launch Conference were successfully held！

The second “Lithium-ion Battery Thermal Test Theme Seminar” and New Product Launch, held on June 23, 2022, in Hangzhou, China, marked a significant milestone in the realm of battery technology. Organized by the China Instrument and Control Society and hosted by Hangzhou Zeal Instruments Science & Technology Co., Ltd. (Zeal Instruments), along with Zhejiang Instrument Holding Group, the event attracted over 60 experts from various fields including lithium battery testing, battery materials, energy storage, and testing instrument technology. The seminar aimed to address the technical bottlenecks faced by the lithium-ion battery industry and explore avenues for advancement.

Keynote Insights: Addressing Critical Issues

Distinguished speakers such as Professor Wang Qingsong from the University of Science and Technology of China, Professor Fan Xiulin from Zhejiang University, Director He Yuanhua from the Civil Aviation Safety Engineering College of Civil Aviation University of China, Associate Professor Lin Chunjing from Chongqing University of Technology, Professor Zheng Siqi from Tsinghua University, Dr. Ma Tianyi, Technical Director of China Automotive Technology and Research Center, and senior engineer Zhou Fei from CSA Group shared their profound insights into enhancing battery safety through their respective research endeavors. Topics ranged from thermal management system design and optimization to the importance of accurate thermal property parameters such as thermal conductivity, specific heat capacity, and heat transfer coefficient.

Innovative Solutions for Testing Challenges

One of the significant challenges highlighted during the seminar was the lack of effective testing methods and instruments for measuring the thermal conductivity of battery cells, particularly for prismatic cells. While feasible methods exist for pouch cell testing, such as 3D thermal property analyzers and steady-state methods, there remains a gap in effective testing techniques for prismatic cells without dismantling the casing. This limitation has led to reliance on empirical values or theoretical models for estimation. Given the substantial presence of prismatic cells in sectors like electric vehicles and energy storage, accounting for over 80% of installations, the development of prismatic cell thermal conductivity testing technology is imperative.

Unveiling Innovative Solutions

In response to the pressing need for advancements in lithium-ion battery testing, Zeal Instruments unveiled their latest innovation—the Dual-state Thermal Parameter Tester, TCA 2SC-080. This groundbreaking instrument offers a novel approach to tackle the industry’s challenges in measuring critical thermal simulation parameters for hard-shell batteries. The TCA 2SC-080 utilizes a two-state testing method based on non-contact temperature measurement with infrared thermography and inverse modeling of heterogeneous heat transfer. This method enables simultaneous measurement of longitudinal and transverse thermal conductivity of the cell core, as well as the thermal contact resistance between the core and the shell.
