Temperature Control Short Circuit Test Chamber

The temperature control short-circuit testing chamber is a dedicated battery safety testing equipment that integrates a precise temperature control environment box and a large current short-circuit circuit. Its core function is to simulate an external short circuit occurring in the battery at the set temperature (normal temperature / high temperature), and to assess whether there is fire, explosion or overheating.

Key Features

(1) High-precision resistance compensation: Automatically compensates for the internal resistance of the circuit, ensuring that the total internal resistance is strictly less than 5mΩ.

(2) Data acquisition and traceability: Automatically records current, voltage, and temperature curves, and can directly export the test report.

(3) Remote control system: Supports remote control by a computer in the separate compartment, ensuring the safety of the operators.

(4) High-current arc extinguishing technology: Effectively suppresses the arc when cutting off high current, protecting the contacts from being burned.

FAQ

1.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.
2.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.
3.Can the short-circuit resistance be switched according to different standards?

OK. 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.
