Energy storage fire protection

The principle of large-scale fire testing is to evaluate the safety of an actual energy storage system or its components in terms of thermal runaway, fire spread and toxic gas release by simulating the behavior of the system under extreme fire conditions. The single or multiple cells in the PACK are triggered by heating, and the thermal runaway gas is ignited by the ignition needle or spray gun flame. The combustion of the gas in the chamber again triggers the thermal uncontrolled spread of the cell, and the results of the continuous burning of the flame are observed.

Through this test, we can fully understand the reaction mechanism of the energy storage system in the fire, the flame propagation path and the effectiveness of the fire extinguishing system, so as to evaluate the safety performance of the system and make suggestions for improvement.

The main objective of the large-scale fire testing is to verify the performance of the energy storage system under extreme fire conditions by simulating the performance of the energy storage system under extreme fire conditions. Test whether the unit system cabinet explosion-proof blowout meets the requirements of the actual scene, whether the system cabinet can control the fire within the initiation unit, ensure thermal runaway or fire does not spread to adjacent units, and whether the planned safety spacing can meet the requirements under such harsh conditions.

This test provides the basis for design optimization, policy development and safety standards to ensure that energy storage systems can reduce fire spread, control thermal runaway, avoid explosions, and effectively protect people and property in the event of a fire.
