[0036] An electric vehicle (1) may be a vehicle that can be moved based on electric energy. The electric vehicle (1) may be equipped with a battery pack (2), and the vehicle may be driven using the electric energy stored in the battery pack (2). The battery pack (2) may have battery modules built into it, and the battery modules may have battery cells built into them. The electric vehicle (1) illustrated in Fig. 1 may be an electric bus, but may not be limited thereto.

[0037] If the electric vehicle (1) is an electric bus, the battery pack (2) may be placed on the upper part of the vehicle body. In a structure where the battery pack (2) is placed on the upper part of the vehicle body, if a fire or fire risk occurs in the battery pack (2), it may be difficult to take immediate action from the outside unless a fire extinguishing system optimized for the structure is built in.

[0038] The electric vehicle (1) may include an automatic fire extinguishing device (10). If the electric vehicle (1) is equipped with an automatic fire extinguishing device (10), even if a fire risk occurs in the battery pack (2), immediate extinguishment can be achieved inside the electric vehicle (1).

If the sensor (14) senses temperature in different ways, the temperature of the battery pack (2) and / or modules can be sensed more accurately.

[0046] When the sensor (14) includes multiple sensors, each sensor may include multiple sensors capable of sensing in different ways.

[0047] The automatic fire extinguishing device (10) may include a control unit.

[0048] The control unit can be electrically connected to the digestion unit (11), the driving unit (12), and the sensor (14).

[0056] When the sensor (14) includes a plurality of sensors, the automatic fire extinguishing device (10) can control the fire extinguishing cover (110) to cover the battery pack (2) when each of the first temperature value and the second temperature value exceeds a specific temperature.

[0057] The automatic fire extinguishing method of the automatic fire extinguishing device (10) may include a fire extinguishing agent spraying step according to S130. For example, the automatic fire extinguishing device (10) may spray the fire extinguishing agent onto the battery pack (2) after the battery pack (2) is covered by the fire extinguishing cover (110).

[0058] If it is determined that the temperature measurement value does not exceed a specific temperature, the operation according to S140 can be performed.

[0059] The automatic fire extinguishing method of the automatic fire extinguishing device (10) may include a step of determining whether some of the modules satisfy the temperature conditions according to S140. If the automatic fire extinguishing device (10) determines that some of the modules exceed a specific temperature in the step according to S140, it may perform an operation according to S150.

[0060] The automatic fire extinguishing method of the automatic fire extinguishing device (10) may include a step of providing a warning notification according to S150. For example, the automatic fire extinguishing device (10) may provide a warning notification to the user for the modules via a user interface when one of the first temperature value and the second temperature value exceeds a specific temperature.

[0061] The automatic fire extinguishing method of the automatic fire extinguishing device (10) may include a manual mode that operates based on a user's manual input. For example, the control unit may control the fire extinguishing cover (110) to cover the battery pack (2) when the user's manual input is obtained through the user interface (70). Specifically, the automatic fire extinguishing device (10) may provide the user with a warning notification through the user interface to obtain the user's manual input when one of the first temperature value and the second temperature value exceeds a specific temperature. Alternatively, the user interface of the automatic fire extinguishing device (10) may be arranged to obtain the user's manual input regardless of whether the first temperature value and the second temperature value exceed the specific temperature.

[0062] As described above, the automatic fire extinguishing device (10) can control the fire extinguishing cover (110) to cover the battery pack (2) when obtaining a user's manual input through the user interface. Accordingly, the fire extinguishing operation can also be performed according to the user's manual operation.

[0063] As described above, the automatic fire extinguishing device (10) automatically extinguishes the battery pack (2) using the automatic fire extinguishing method described above, thereby enabling rapid and immediate fire prevention through structural deformation in response to fire hazards. Furthermore, the automatic fire extinguishing device (10) can effectively prevent fires through rapid spraying of extinguishing agents in response to fire hazards.

Accordingly, even if the connecting member (13) is melted by high heat, the fire cover (110) can stably cover the battery pack (2) by being supported by the rotation shaft support (220).

[0070] The storage unit (100) may be installed on one side of the battery pack (2), and the driving unit (12) may be installed on the other side of the battery pack (2).
