Battery Combustion Test Chamber

After the battery has been fully charged in accordance with the test method specified in Section 4.5.1, place the battery on the wire mesh of the test fixture. If the battery slips off during the test, use a single metal wire to secure the battery sample to the wire mesh. If this does not occur, do not bundle the battery. Apply heat to the battery with a flame and stop heating when any of the following three conditions is met:

1. Battery explosion;

2. The battery is completely burned;

3. Continuous heating for 30 minutes, provided that the battery has neither caught fire nor exploded.

1. The test net is made of stainless steel, making it easy to clean and maintain.

2. The front of the enclosure features a visible tempered glass observation window.

3. A smoke exhaust sleeve is installed at the rear of the enclosure. It can be connected to an external exhaust duct to quickly discharge hot air generated during the test.

4. Ignition can be controlled remotely via a remote control.

The bottom of the protective compartment is equipped with universal casters for easy handling and positioning.
