The medium-large energy storage system is usually formed by assembling batteries into modules, then the modules are assembled into packs, then the packs form high-voltage or (and) high-energy battery clusters in a series-parallel connection mode for use, and then the plurality of battery clusters form the large energy storage system in a series-parallel connection mode. And with the increase of lithium ion battery energy density, the safety problem is also more outstanding, and lithium ion battery often causes the thermal runaway and leads to catching fire even explosion because of product defect or misuse, consequently often needs to adopt fire control facility in order to ensure safe energy storage system.
The existing fire extinguishing system generally has various fire sensors to detect the fire alarm information of an energy storage system in real time, when the fire alarm is acquired, a protection system sends corresponding instructions to a controller according to the information to process, and the existing fire extinguishing system comprises a heptafluoropropane fire extinguishing system, a perfluorohexanone fire extinguishing system, high-pressure water mist, water spray and the like.
According to the technical scheme, on one hand, fire safety signals are transmitted in a multi-stage mode or a single-path mode, transmission is slow, unreliable factors exist in the transmission process, and the optimal fire fighting time or fire fighting errors are missed when the response is slow; on the other hand, the method for treating the fire-fighting problem is single, and a large amount of fire-fighting agent is needed to have excessive fire-fighting or destructive fire-fighting, so that equipment is unnecessarily damaged; thirdly, when adopting at Pack internally mounted miniature fire-fighting equipment, can cause the change of Pack structure to it is difficult to carry out fire protection to specific thermal runaway battery accurately.
