That is, the terminal end of the first path providing unit (21) can be inserted into the internal module (111) of the battery pack (110) so that the fire extinguishing operation on the battery cells (112) can be effectively performed.

[0055] A nozzle may be provided at the end of the first path providing unit (21) to spray fire extinguishing agent onto the battery cells (112) inside the module (111).

[0057] A one-way nozzle may be provided at the end of the second path providing unit (22).

[0064] The automatic fire extinguishing method of the automatic fire extinguishing device (1) may include a temperature identification step of identifying a first temperature value and a second temperature value, which are real-time temperatures of a measurement target, according to S100. For example, the control unit (50) may identify the first temperature value and the second temperature value, which are real-time temperatures of at least one measurement target, using the first temperature sensor and the second temperature sensor of the temperature sensor unit (40), respectively. Specifically, for example, the control unit (50) may identify the real-time temperature of the battery pack (110) using the first temperature sensor and the second temperature sensor of the first temperature sensor unit (41). The control unit (50) may similarly perform real-time temperature identification for the battery pack (110) for the motor (120) and the inverter (130).

[0065] The automatic fire extinguishing method of the automatic fire extinguishing device (1) may include a step of determining whether each of the first temperature value and the second temperature value exceeds a threshold temperature value, according to S110.

[0066] If the control unit (50) determines that each of the first temperature value and the second temperature value exceeds the threshold temperature value, it can perform the operation according to S120.

[0067] If the control unit (50) determines that each of the first temperature value and the second temperature value does not exceed the threshold temperature value, it can perform the operation according to S130.

[0068] The automatic fire extinguishing method of the automatic fire extinguishing device (1) may include a step of spraying a fire extinguishing agent according to S120. The control unit (50) may control the valve unit (30) to open the path providing unit (20) when each of the first temperature value and the second temperature value exceeds a threshold temperature value, so that the fire extinguishing agent may be sprayed toward at least one measurement target from the end of the path providing unit (20). Specifically, for example, the control unit (50) may control the first valve unit (31) to open the first path providing unit (21) so that the fire extinguishing agent may be sprayed to the battery pack (110) when it is determined that each of the first temperature value and the second temperature value for the battery pack (110) exceeds a threshold temperature value. The control unit (50) may similarly perform the control operation of the first valve unit (31) for the battery pack (110) for the motor (120) and the inverter (130).

[0069] The automatic fire extinguishing method of the automatic fire extinguishing device (1) can determine whether some of the temperature values ​​satisfy the temperature conditions according to S130.

[0070] If the control unit (50) determines that one of the first temperature value and the second temperature value for the battery pack (110) exceeds the threshold temperature value, it can perform the operation according to S140.

[0071] The control unit (50) can terminate the operation if it determines that neither the first temperature value nor the second temperature value for the battery pack (110) exceeds the threshold temperature value.

[0072] If the control unit (50) determines that one of the first temperature value and the second temperature value for the battery pack (110) exceeds the threshold temperature value, the control unit (50) may provide a warning notification to the user according to S140. For example, if one of the first temperature value and the second temperature value exceeds the threshold temperature value, the control unit (50) may provide a warning notification for at least one measurement target to the user through the user interface (70).

[0073] For example, if the control unit (50) determines that only one of the first temperature value and the second temperature value for the battery pack (110) exceeds the threshold temperature value, the control unit (50) may provide a warning notification for the battery pack (110) to the user through the user interface (70). The control unit (50) may similarly perform the warning notification operation for the battery pack (110) for the motor (120) and the inverter (130).

[0074] The control unit (50) can open the valve unit (30) so that the extinguishing agent is sprayed when it obtains a spray input, which is a manual input from the user, through the user interface (70). For example, the user interface (70) is provided to obtain a spray input from the user to spray the extinguishing agent, and the control unit (50), when it obtains the spray input, can open the valve unit (30) so that the extinguishing agent is sprayed. As another example, when at least one of the first temperature value, the second temperature value, and the gas generation amount exceeds a threshold value including a critical temperature value and a critical generation amount, the control unit (50) can provide a warning notification to the user so that it can obtain a spray input, which is a manual input for at least one measurement target, through the user interface (70). At this time, the user can manually input the spray input through the user interface (70), and the control unit (50), when it obtains the spray input, can open the valve unit (30) so that the extinguishing agent is sprayed.

[0075] By spraying the fire extinguishing agent according to the temperature identification of the automatic fire extinguishing device (1) described above, fire and the spread of fire to measurement objects such as the battery pack (110), motor (120), and inverter (130) can be quickly prevented.

[0079] A first nozzle (21-1) may be provided at the end of the first path providing unit (21). The first nozzle (21-1) may be a wide-angle nozzle or a multi-directional nozzle for spraying the fire extinguishing agent over a wide area from the upper portion of the battery cells (112).

[0080] According to a structure such as Fig. 4, digestion work on battery cells (112) can be effectively performed over a wide area.

[0081] Referring to FIG. 5, the terminal portion of the first path providing unit (21) can be designed to be positioned between the internal battery cells (112) of the battery module (111).

[0082] A second nozzle (21-2) may be provided at the end of the first path providing unit (21). The second nozzle (21-2) may be positioned between battery cells (112) and may spray a fire extinguishing agent on surrounding battery cells (112). The second nozzle (21-2) may be a multidirectional nozzle (e.g., a twin nozzle) for concentrated spraying on surrounding battery cells (112).

[0083] According to a structure such as Fig. 5, the digestion operation can be intensively performed on the battery cells (112) around the nozzle.

[0084] Referring to FIG. 6, the terminal portion of the first path providing unit (21) may extend between the internal battery cells (112) of the battery module (111). At this time, a first nozzle (21-1) and a second nozzle (21-2) may be installed at a predetermined interval at the terminal portion of the first path providing unit (21). Specifically, the first nozzle (21-1) may be installed to be positioned above the battery cells (112), and the second nozzle (21-2) may be installed to be positioned between the battery cells (112).
