Frequently Asked Questions (FAQ)
1. What should be done if the contactor gets "stuck" and the current cannot be cut off?
This is a common safety hazard existing in high-current testing. To address this, the equipment adopts a dual physical disconnection protection mechanism: in addition to the main contactor, an emergency safety air switch or physical fuse device is configured. In case of abnormal contact welding, forced power-off is instantly executed via the secondary circuit.
2. How does the equipment capture the instantaneous peak value of short-circuit current?
The short-circuit current surges at a millisecond level. The system uses a ultra-high-speed data acquisition module (100kHz+) paired with specialized high-frequency current sensors (such as Rogowski coils and precision non-inductive shunts) to flawlessly capture real-time peak current waveforms.
3. Can different battery voltage levels be tested on the same unit?
Yes. The system supports wide-range voltage test configurations (DC 5V up to 1500V). Operators can simply set custom safety cutoff thresholds and voltage ranges via the software control panel to test varying battery cells, modules, or packs.
4. Can the internal short-circuit resistance value be customized?
Yes, we offer both fixed ultra-low resistance options (<5mΩ for standard vacuum contactors) and adjustable resistance configurations (1mΩ to 100mΩ or higher) using temperature-stable constantan alloy elements to satisfy different international testing standards.
5. What explosion-proof customization options are available for battery failure tests?
We offer explosion-proof test chambers ranging in volume from 1m³ to 12m³ with steel plate wall thicknesses from 5mm up to 12mm (single or double-layered), complete with integrated automated smoke exhaust, fire suppression, and pressure relief vents.
6. How is test data exported and integrated into laboratory management systems (LIMS)?
The test machine is equipped with standard high-speed Ethernet interfaces and supports standard communication protocols. Test logs, raw curves (V, I, T), and result reports can be automatically exported in CSV, Excel, or direct database link formats.
