Description
Technical Field
The utility model relates to the technical field of battery thermal management, in particular to an energy storage and thermal management system with a fire-fighting and fire-extinguishing function.
Background
Along with the expansion of the market of the electrochemical energy storage power station, safety accidents are more and more. The lithium ion battery energy storage system is formed by connecting dozens of battery cells in series and parallel to form a battery box, a plurality of battery boxes are connected in series to form a battery pack string, and the battery pack string are integrally arranged in an energy storage battery cabinet in parallel. A large amount of energy is stored in a closed space in an energy storage system of the lithium ion battery, and the energy storage system has dangerous essence, thermal runaway is a root cause of potential safety hazards of the lithium ion battery, and chain reaction of side reaction caused by small organic molecules causes thermal runaway of the battery. In the fire spreading process, the thermal runaway of the first section of battery monomer is mainly caused, and the thermal runaway of adjacent battery monomers is caused by thermal mass transfer and thermal radiation, so that the fire accident of the whole lithium battery energy storage system is finally caused. The higher the energy density of the lithium ion battery material, the higher the safety risk, and the greater the risk of thermal runaway. To avoid a fire, the improvement and optimization from a single battery to the whole system are needed, a thermal management system and a fire-fighting system in an energy storage system are optimized, the occurrence of thermal runaway and thermal diffusion is controlled and even avoided, and timely and effective fire fighting is guaranteed.
The battery energy storage system mainly comprises a thermal management (namely heat exchange) system and a fire fighting system, wherein the thermal management system cools the battery energy storage system, and the fire fighting system is used for fire fighting and extinguishment when the battery energy storage system is out of control due to heat.
With the development of high-energy-density battery cells and the increase of the demand of large capacity of energy storage power stations, a thermal management system in an energy storage system plays an increasingly important role in the consistency and stability of a battery system, and the performance of the energy storage system is greatly influenced by the thermal management system. In a battery system, the temperature is an important factor influencing the aging of the lithium battery, and the proper working temperature can slow down the aging of the battery and simultaneously exert the optimal performance of the battery. In a battery energy storage system, thousands of battery monomers are integrated in one system, and the consistency of the performance of the monomers directly influences the overall performance and service life of a battery pack. The battery system has different natural heat dissipation conditions at different positions, and consistent working temperature needs to be created if consistent aging progress is obtained. However, the plurality of batteries are powered on at the same time, so that a heating phenomenon inevitably occurs, and particularly, in an environment with a high temperature, the heating phenomenon of the battery pack is serious, the batteries can be burnt excessively and even explode, so that a serious potential safety hazard exists, and the service life of the batteries is influenced.
At present, the cooling mode of the battery in the energy storage power station generally adopts two modes of air cooling and water cooling. The air cooling mainly depends on external cold air to cool the battery, so that the heat on the surface of the battery is taken away, but the cooling process is limited by many unstable factors such as air flow and wind speed, so that uneven heat dissipation is easily caused, and the working performance and the service life of the battery are influenced. The water cooling mainly takes away the heat of the battery through water flow to achieve the purpose of cooling, and the cooling mode is uniform, stable, safe and reliable in cooling.
Heptafluoropropane gas is commonly used for fire protection in a fire protection system, and hexafluoropropane, perfluorohexanone and the like are also used. Heptafluoropropane is a clean gas chemical fire extinguishing agent which mainly uses chemical fire extinguishing and has physical fire extinguishing function, and belongs to polyfluorinated alkane; it is colorless, odorless, low-toxicity, non-conductive, does not contaminate the protected object, and does not damage property and precision facilities. Heptafluoropropane is a halogenated alkane substitute, and a decomposition product generated in the fire extinguishing process is a weakly acidic gas, so that the environment is influenced and the greenhouse effect is generated when the decomposition product is discharged into the atmosphere. Although the inert gas is composed of gas naturally existing in the atmosphere, and is nontoxic and free of corrosive decomposition products, the smoke generated in a fire disaster affects the environment.
However, the thermal management system and the fire fighting system in the existing battery energy storage system are independent and information is not interconnected, so that the battery energy storage system occupies a large space and is high in cost.
