Description

Fire Extinguishing Battery Test System The present invention relates to a battery test system capable of fire suppression, and more specifically, to a battery test system capable of suppressing a fire and preventing the spread of fire when a fire occurs in a battery during a battery test. Generally, an electric vehicle refers to a vehicle that generates driving force by using a high-voltage battery to supply electrical energy from the battery to an electric motor. Electric vehicles include pure electric vehicles (EVs), hybrid vehicles (HEVs), and rechargeable hybrid vehicles (PHEVs). While HEVs and PHEVs are classified as eco-friendly vehicles because they utilize both electricity and internal combustion engines and use some fossil fuels, pure electric vehicles can be considered eco-friendly vehicles because they do not use fossil fuels and produce almost no exhaust gas emissions or noise. The batteries primarily used in electric vehicles are lithium-ion rechargeable batteries. While lithium-ion rechargeable batteries have the advantages of having the highest unit cell voltage (3.0–3.7V) and excellent energy density among existing rechargeable batteries, they have the disadvantage of being susceptible to high current characteristics, overcharging, and over-discharging. Furthermore, if the separator that separates the main components of a lithium-ion battery—the cathode and anode—is damaged and the two electrodes come into contact, excessive current flows and heat is generated, which can lead to a fire. Additionally, because lithium-ion rechargeable batteries used in electric vehicles are subjected to repeated charging and discharging cycles, battery safety has emerged as a critical issue. As such, fires involving high-voltage batteries used in electric vehicles and the like are rapidly increasing due to problems such as overheating caused by repeated charging and discharging, internal short circuits connecting the batteries, and damage to chargers and separators. Since battery fires cause widespread damage to surrounding vehicles, facilities, and buildings, significant efforts and urgent improvements are required to protect valuable lives and property. In particular, there has been a problem where the spread of damage is exacerbated because the explosion of a battery generates ultra-high temperature thermal energy, flames (smoke), and flammable gases, making it nearly impossible to extinguish with fire extinguishers. A battery test system refers to a system that verifies the performance of a secondary battery and tests its safety by placing the battery on a test bed and repeatedly performing rapid charging and discharging. In particular, high-capacity charging and discharging devices generate a significant amount of heat due to overheating because they enable rapid charging and discharging of the battery, and consequently, there is a constant risk of fire. Although fire extinguishers are provided due to the risk of ignition during charging and discharging tests, there is a problem in that it is difficult to completely extinguish a lithium-ion battery using only a fire extinguisher.
