Technology Field

[0001] The present invention relates to a fire suppression system, and more specifically, to an agricultural battery fire suppression system capable of storing an agricultural battery inside a case and supplying water into the case to suppress a fire in the event of a fire in the agricultural battery. Background Technology

[0002] With the increasing technological development and demand for mobile devices such as smartphones, laptops, and digital cameras, technologies related to rechargeable secondary batteries are becoming more active. Furthermore, secondary batteries serve as an alternative energy source to fossil fuels that cause air pollutants and are being applied to electric vehicles (EVs), hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (P-HEVs), and energy storage systems (ESS).

[0003] Currently, widely used types of rechargeable batteries include lithium-ion batteries, lithium-polymer batteries, nickel-cadmium batteries, nickel-hydrogen batteries, and nickel-zinc batteries.

[0004] The operating voltage of these unit secondary battery cells, that is, unit battery cells, is approximately 2.0V to 5.0V. Therefore, if a higher output voltage is required, multiple battery cells may be connected in series to form a cell module assembly, and cell module assemblies may also be connected in series or parallel to form a battery module depending on the required output voltage or charge / discharge capacity. Furthermore, it is common to manufacture a battery pack by adding additional components using at least one of these battery modules.

[0005] Meanwhile, in the case of battery modules, there is a risk that the stability and efficiency of battery cells may deteriorate due to the heat generated during charging and discharging, and various methods are being applied to cool the battery modules to prevent this.

[0006] For example, an air-cooling system using cooling gas can be used, in which case it is common to be equipped with devices such as cooling fans.

[0007] When using the aforementioned cooling fan, it fails to perform its function in the event of a fire, so an alternative solution to improve this is required.

[0008] The aforementioned technical configuration is provided as background technology to aid in understanding the present invention and does not constitute prior art widely known in the technical field to which the present invention belongs. Prior art literature
