Overview
The battery thermal impact test box is a professional test equipment used to evaluate the performance and safety of batteries under extreme temperature changes. The device simulates the reaction of batteries in a rapidly changing temperature environment, and is mainly used to test whether batteries can remain stable and safe under extreme temperature conditions. It is suitable for various types of batteries such as lithium-ion batteries and nickel-metal hydride batteries, especially for applications in demanding environments such as automotive, aerospace and military.
Features
1. Touch screen Control mode, easy to operate
2. Temperature range, from room temperature to 150 ℃, display accuracy +/- 0.1 ℃
3. The inner box is made of 304 stainless steel, which has strong durability
4. Fast heating rate, average heating rate 5 +/- 2 ℃/min (non-linear no-load)
5. Equipped with double-decked tempered Glass observation window for real-time monitoring
6. Built-in safety devices, including over-temperature alarm and MCCB overload protection
7. Explosion-proof design, including explosion-proof ports and explosion-proof door locks, to ensure test safety
Principle
The battery thermal impact test chamber simulates the extreme temperature environment by controlling the rapid change of internal temperature. The device is heated to the set temperature (such as 130 +/- 2 ° C) at an average heating rate of 5 +/- 2 ° C/min and maintained for a certain time to test the reaction of the battery at high temperature. The control system realizes the functions of temperature-to-timing and time-to-timing to ensure the accuracy of the test process, and finally evaluates the safety of the battery by observing whether it explodes, catches fire or deforms.
Applications
Automotive, aerospace, and military applications
Steps
1. Put the charged battery into the test chamber
2. Set temperature parameters, such as 130 +/- 2 ° C or 70 +/- 2 ° C
3. Start the device and heat up at a rate of 5 +/- 2 ° C/min
4. Maintain the specified time at the set temperature (e.g. 10 minutes or 7 hours)
5. After the test, remove the battery and chill down to room temperature
6. Check the battery for explosion, fire or physical deformation
Notice
Make sure the battery is fully charged before testing
Avoid opening the explosion-proof door during equipment operation to prevent accidents
Regularly check safety devices such as over-temperature alarm function
* After the test, the battery needs to be chilled down to room temperature before processing
Follow equipment specifications to avoid overloading
