❓ Frequently Asked Questions
-
Although all types of tests simulate battery short circuits, the FISC mandatory internal short circuit test (in accordance with JIS C 8714 and IEC 62133) has the highest accuracy and is the closest to the real manufacturing defect scenarios.
Conventional compression/needle puncture: This belongs to external severe damage, simulating severe deformation caused by external force impact.
FISC: This simulates spontaneous internal short circuits caused by the introduction of metal impurities (such as nickel chips) during production. It requires slowly applying pressure to the preset nickel sheet position in a temperature-controlled environment, with extremely high requirements for pressure control accuracy (0.1N level) and voltage drop detection sensitivity. -
According to the JIS C 8714 standard, the equipment needs to monitor voltage changes in real time. The testing equipment is equipped with a high-frequency data acquisition system:
Automatic shutdown trigger: When the battery voltage drops (typically 50mV), the servo motor is controlled to stop applying pressure and maintain pressure within milliseconds.
Dual judgment logic: It can simultaneously use pressure compliance (such as 800N) or displacement compliance as the shutdown conditions.
The high sensitivity control can avoid excessive pressure causing an external short circuit, accurately reproducing the instant when an internal short circuit occurs. -
This is precisely where the core difference lies between professional equipment and low-end equipment:
Precise servo control: Utilizing high-precision AC servo motors and precise ball screws, it can achieve ultra-smooth operation at speeds as low as 0.1mm/s, eliminating the common crawling and jitter problems in hydraulic systems.
High-precision load sensors: Pressure fluctuations are controlled within ±0.5%, fully meeting the strict requirements of standards for pressure application rate and pressure accuracy throughout the process. -
The tester is designed with precisely customized fixtures to accommodate a wide range of battery form factors, including cylindrical cells, prismatic (square) cells, and pouch-type batteries. The interchangeable pressure heads and fixture adapters ensure secure and consistent positioning for each battery type, enabling accurate and repeatable test results across different product lines.

The equipment incorporates multiple layers of safety protection to handle thermal runaway scenarios:
The explosion-proof steel enclosure with reinforced observation glass contains any sudden energy release. Integrated smoke detectors automatically trigger the exhaust ventilation system. Reserved fire suppression ports allow direct connection of nitrogen or CO₂ extinguishing systems. A dedicated pressure relief door prevents dangerous overpressure build-up inside the test chamber, ensuring operator safety at all times. -
Yes. The built-in software supports one-click export of complete test reports in both PDF and Excel formats, fully compliant with IEC and JIS reporting requirements. All recorded parameters — including pressure, voltage, temperature, and displacement — are synchronized and timestamped, making it straightforward to import data into existing QMS or laboratory information management systems (LIMS). Remote monitoring also allows real-time data access without being physically present at the equipment.
