Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy storage, in particular to an energy storage battery box integrated with exhaust type fire extinguishing structure. BACKGROUND

[0002] The energy storage battery box is a compact and integrated small-sized electric energy package storage device, which is different from industrial large-capacity battery cabinets. The mainstream adopts lithium iron phosphate battery core, is matched with inverter, battery management system BMS and other core components, and is modularized designed. The energy storage battery box can be flexibly expanded according to the power demand. The core function of the energy storage battery box is to realize the storage and on-demand release of electric energy. When the power grid is powered off, the energy storage battery box can be seamlessly switched to provide emergency power supply for various key power equipment. When the energy storage battery box is matched with photovoltaic panels and other renewable energy devices, the energy storage battery box can store excess electric energy to avoid the waste of clean energy. At the same time, the energy storage battery box can utilize the difference between peak and valley electricity prices to charge in the low valley period and discharge in the peak period, thereby reducing the electricity cost. In terms of safety, the built-in BMS can monitor the battery voltage, temperature and other parameters in real time, has overcharge, overdischarge and overtemperature protection functions, and some products also have dustproof, waterproof and protective functions to ensure the operation safety. The energy storage battery box is an important equipment for improving the flexibility and stability of power supply.

[0003] In the Chinese patent with the application number CN114976470B, an energy storage battery box is disclosed, which comprises a battery pack and a fire safety assembly. The fire safety assembly comprises a bottom plate, an intermediate partition plate and a top plate. The bottom plate and the intermediate partition plate form a flow guide chamber, and the intermediate partition plate and the top plate form a fire chamber. By setting the flow guide chamber and the fire chamber as independent guide spaces, and by processing the thickness of the bottom of the first recess and the thickness of the bottom of the second recess, the fluid after thermal runaway is first broken through the first thinning part and guided out of the flow guide chamber, preventing the pressure in the battery cell unit from rising sharply and exploding. Then, when the impact force of the fluid continues to increase and breaks through the second thinning part, the fire fluid is introduced into the battery cell unit through the fire chamber for fire extinguishing, avoiding the problem of immediate release of fire fluid to prevent the outward release of high-temperature fluid, reducing the explosion risk of the battery cell unit, and improving the reliability of the entire energy storage battery box.

[0004] In the above-mentioned patent, when a fire occurs, the thermal runaway fluid is first guided to be discharged outward, and then the fire fluid is released through the fire chamber to cover and extinguish the fire inside. The battery packs in the existing energy storage battery box are tightly attached. In this process, both the high-temperature fluid generated by burning and the fire fluid used for extinguishing the fire will affect all battery packs without distinction, thereby causing the problem of reduced safety of the energy storage battery box.
