FAQ
1. What is the primary difference between the Forced Internal Short Circuit (FISC) test and standard crush or nail penetration tests?
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.
2. How does the tester accurately determine the "end of test" point to ensure compliance?
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.
3. How is the pressure precision maintained during the slow-speed compression process?
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.
