(Central News Agency reporter Chang Chien-chung, Hsinchu, 30th) TSMC has launched a lithium iron battery generation upgrade plan. In the first quarter of this year, the first and second generation lithium iron battery management systems were fully upgraded to the third generation, which can precisely detect voltage, charge, current, temperature, and health, and transmit data in real time to the factory monitoring and data collection systems, enhancing energy storage safety and management efficiency.
TSMC stated in its newly released ESG (Environmental, Social, and Governance) e-newsletter that lithium iron batteries possess high energy efficiency, long cycle life, and environmental protection characteristics, making them important components for stable UPS operation and optimized energy efficiency.
After completing in-house production line verification in 2017, TSMC began using first-generation lithium iron batteries and monitored voltage through sampling boards to ensure system operation safety. In response to the IEC62619 industrial application secondary lithium-ion battery safety standard issued by the International Electrotechnical Commission, TSMC introduced second-generation lithium iron batteries in 2018. The battery management system (BMS) on these batteries, in addition to voltage, added monitoring functions for charge, temperature, and health, improving the overall monitoring capability of battery status.
To deepen its continuous investment in battery technology and comply with international regulations, in line with the NFPA855 standard for the installation of stationary energy storage systems issued by the U.S. National Fire Protection Association, TSMC began research on third-generation lithium iron battery applications with suppliers in 2019.
TSMC pointed out that the third-generation battery management system (BMS) has the function of monitoring key parameters such as voltage, charge, current, temperature, and health, and integrates with the factory's monitoring and data collection systems, achieving real-time data transmission and remote diagnosis. When an abnormality occurs, the fault point can be immediately determined, improving overall response efficiency by 25%.
TSMC stated that in 2024, it further conducted thermal runaway experiments on lithium iron batteries to verify their safety performance under extreme conditions, laying a reliable foundation for the upgrade of existing systems.
TSMC pointed out that while fully upgrading the lithium iron battery management system to the third generation, TSMC also developed a lithium iron battery switch interlock trip device. This device can automatically cut off the power supply of the lithium iron battery when the BMS detects a battery abnormality, avoiding potential hazards and improving system operation safety. The installation of the trip device is expected to be completed by 2027, embodying the commitment to the highest standards of battery safety.
In addition, to deepen internal and external understanding of water resource sustainable management, TSMC focuses on two major educational promotion themes: wafer fab water management actions and recycled water plant exploration journeys. Through diverse courses and guided tours, it promotes employee and public attention and support for water resource protection.
TSMC stated that as of April this year, the cumulative number of participants has exceeded 6,800. TSMC also collaborated with the TSMC Charity Foundation to organize a recycled water plant parent-child camp, injecting new vitality into promoting sustainable development concepts through parent-child learning and on-site exploration of recycled water plant operations.
