[0002] With the rapid development of electric vehicles and other fields, battery safety has become a focus of public attention. Preventing battery fire failure is a critical step in ensuring battery system safety. New plastics must be able to withstand high temperatures and withstand jet flames exceeding 1000°C without burning through, achieving a higher level of flame resistance and effectively preventing the spread of fire. In the electronic control systems of batteries and home appliances, new plastics can directly replace mica boards or other thermosetting resin materials, improving battery fire resistance and reducing costs.

[0073] (3) Through the adjustment and positioning function of the guide rail group, it can clamp a variety of test samples and the flame ablation position of the test samples, and can also adjust the distance between the flame and the sample.

[0074] (4) The rotating cylinder 132 drives the fire baffle 131 to achieve isolation and ablation between the sample and the flame.

[0075] (5) Multiple gas passages are distributed inside the burner 121, and the opening and closing and flow of each gas passage are controlled by an electrical control system to achieve flame temperature and power control, as well as to simulate the jet flame effect when the battery is burning.

[0076] The design points of box 2 include:

[0077] (1) A test device 1 and a control mechanism 3 are installed inside. The test operation surface is equipped with a glass door test window 21 that can be opened and closed, an operation display screen 31, an extinguishing button 32, an ignition button 33, and a power switch 34.

The PLC controls the gas and supporting gas solenoid valves and flowmeters. Gas is first introduced into the burner at the set ignition flow rate. The igniter activates, igniting the flame. Ignition is considered successful when the ignition temperature reaches the set value. Then, the burner is introduced at the set flow rates for gas, supporting gas, and flame cooling gas. Observe the temperature measured by the flame damper temperature sensor. When the flame temperature reaches the required range, press the "Start Test" button on the control panel. The flame damper rotates, and the flame begins ablation of the sample. The control system simultaneously records the test time, gas flow rate, and sample backside temperature data. The test can optionally include a jet flame, along with the jet interval and duration, to simulate the impact resistance of the material under the high temperature of battery combustion. The ablation test duration can be set, and the flame automatically shuts down after the set duration. If the sample burns through or encounters other problems during the test, the flame must be manually stopped by clicking the flameout button.
