Smoke from National Energy Storage System Testing Center Was from Large-Scale Combustion Test, Says Ministry of Economic Affairs
Thick smoke billowed from the National Energy Storage System Testing Center in Miaoli this afternoon, raising public concern. The Bureau of Standards, Metrology and Inspection (BSMI) of the Ministry of Economic Affairs explained tonight that this was a large-scale combustion safety test on a battery cabinet sample submitted by a manufacturer. The smoke produced after combustion is a possible phenomenon, and safety monitoring and smoke extraction mechanisms were activated according to standard operating procedures. There were no injuries and no equipment was damaged.

(Central News Agency, Taipei, 14th) Thick smoke billowed from the National Energy Storage System Testing Center in Miaoli this afternoon, raising public concern. The Bureau of Standards, Metrology and Inspection (BSMI) of the Ministry of Economic Affairs explained tonight that this was a large-scale combustion safety test on a battery cabinet sample submitted by a manufacturer. The smoke produced after combustion is a possible phenomenon, and safety monitoring and smoke extraction mechanisms were activated according to standard operating procedures. There were no injuries and no equipment was damaged.
The BSMI pointed out in a press release that the National Energy Storage System Testing Center is a professional laboratory for conducting safety tests on energy storage systems and related battery products. This time, a large-scale combustion safety test was conducted in accordance with national standards. The main purpose was to simulate a battery thermal runaway scenario to observe the subsequent fire and smoke conditions.
The BSMI stated that the above test data will be converted into relevant scientific data and parameters, which will serve as an important basis for future fire safety design and risk management of energy storage products.
Regarding public safety concerns, the BSMI emphasized that the test was conducted in a dedicated combustion test laboratory with 50-centimeter-thick walls and a complete fire safety design. During the test, the actual installation scenario of an energy storage container was simulated, and fire-resistant gypsum boards were installed around the sample for protection.
The BSMI said that since large-scale combustion tests may produce a large amount of smoke, the fire department was notified before execution, and safety monitoring and smoke extraction procedures were carried out according to standard procedures. This incident did not cause any damage to the test equipment, and the function of the testing center and subsequent testing services are not affected.
The National Energy Storage System Testing Center was inaugurated in the Tongluo Science Park in December 2024. The BSMI stated in a press release at the time that after its opening, it became the largest energy storage system safety testing laboratory in the country. It has completed the construction of fire, combustion, vibration, and environmental testing laboratories, has the most complete testing items, and has the capacity for 360 kW/360 kWh energy storage system safety testing, making it a world-class energy storage system safety testing laboratory.
