FAQ
-
Q Why must the short-circuit resistance be controlled below 5mΩ or 10mΩ?Most international standards such as UN38.3 require extremely low external short-circuit resistance to simulate the most severe extreme short-circuit conditions. If the internal resistance of the equipment circuit is too high, it will result in insufficient peak short-circuit current, making it impossible to truly and accurately evaluate the safety performance of the battery.
-
Q What is the impact of sampling frequency on the short-circuit test?The current change during the moment of battery short circuit is extremely intense and belongs to a microsecond-level transient process. If the sampling frequency is too low (for example, collecting once every 1 second), it will be impossible to capture the true peak current. This device supports the highest 1000Hz (1ms interval) high-speed sampling, which can fully record the entire process data curve.
-
Q Can the short-circuit resistance be switched according to different standards?Yes. We offer a multi-range resistance switching solution. Through software or manual insertion and removal of the switch, you can quickly switch between different specifications such as 5mΩ, 20mΩ, and 80mΩ, meeting various standard testing requirements.
-
Q What battery types are compatible with the TA-WDL-1000A short-circuit test chamber?The TA-WDL-1000A is designed to test polymer, cylindrical, and square battery cells, as well as EV and ESS battery modules. The test room size can be customized to accommodate different battery formats and capacities, from consumer-grade cells to large-scale EV battery modules.
-
Q How does the remote video surveillance option work?An optional monitoring camera is installed outside the explosion-proof window of the test chamber. It enables operators to remotely observe the testing status in real time without being physically present near the chamber. The camera features a resolution of at least 1080P and a pixel count of no less than 5 million for clear visibility.
-
Q What are the temperature control capabilities of the test chamber?The chamber supports a temperature range from room temperature +10°C up to 100°C, with a temperature rise rate of 5°C ± 2°C/min (non-linear adjustable). The temperature can be precisely adjusted in increments of 0.5°C, and temperature uniformity is maintained within ±2°C under unloaded conditions, ensuring consistent and reliable test environments.
