Patents.2024101731385 | 2024202874269
- The top cover of the box integrates a fire-fighting shared air circuit and TVOC monitoring probe, which automatically activates the fire-fighting system in case of thermal runaway of the battery.
- In the event of thermal runaway of the battery, the gaseous electrolyte ejected from the battery enters the fire-sharing air path through the top cover of the case.
- Cooling down and liquefying the gaseous electrolyte of the battery eruption using firefighting solutions.
- Adsorption, filtration and recycling of liquefied hazardous gases through purification and adsorption tanks.
- Ensure that the smoke emission is orderly and controllable, without leakage, and fundamentally solve the problem of thermal runaway of the battery.

- The system monitors the gas composition and state of the battery tank in real time through a variety of sensors to ensure timely response and treatment in the event of thermal runaway.
- Gas monitoring: TVOC monitoring probe detects the gas in the battery box in real time, confirms the explosion status and triggers the alarm.
- Pressure Detection: Pressure sensors synchronously monitor the gas pressure in the pipeline, providing additional thermal runaway judgment basis.
- Thermal runaway treatment: After confirming thermal runaway, fire-fighting measures are automatically activated, and fire-fighting solution is injected to cool down and filter the smoke to prevent explosion and fire.
- Liquid level monitoring: Liquid level sensors ensure that the fire-fighting solution is sufficient to guarantee the continuous and effective operation of the system.
Sino-Australia Energy Storage Multi-Cell Thermal Runaway Experiment Video
Sino-Australia Energy Storage commissioned the Tianjin Fire Research Institute of the Ministry of Emergency Management to conduct a third-party on-site witnessing test of the system in late 2024, and the test process of the two thermally uncontrolled cores of the deflagration fumes to complete the effective control of the treatment, and at the same time, the site of the external source of ignition did not produce the phenomenon of combustion and explosion, and the test has been a complete success. Lithium battery fire is essentially a gas fire, similar to liquefied petroleum gas fire, with "first explosion after combustion" characteristics. Traditional clean gas extinguishing agent for this type of gas fire has no obvious fire fighting effect. Sino-Australia Energy Storage has successfully developed a four-dimensional active water-circulating gas circuit fire-fighting system at the electric core level, through the core sub-systems - four-dimensional active monitoring system, PACK built-in water-circulating fire-fighting gas circuit for lithium batteries after thermal runaway to achieve an orderly and controllable cycle of adsorption and treatment of the combustible fumes, to fundamentally solve the battery thermal runaway fires and the risk of explosions. Risks.
