[0032] The present application embodiment first provides a container-type energy storage system. Figure 1 , Figure 1 A schematic structural diagram of a containerized energy storage system provided in an embodiment of the present application.

[0033] like Figure 1 As shown, the containerized energy storage system may include a main box 11 , several sealed sub-boxes 12 , a fire protection module 13 and a control module 14 .

[0034] The number of the sub-boxes 12 may be greater than or equal to two. In practical applications, the number of the sub-boxes 12 may be set according to actual needs and is not specifically limited here.

[0035] In the container-type energy storage system, each sub-box 12 can be arranged in the main box 11, and each sub-box 12 can include several energy storage batteries. In actual applications, the several energy storage batteries can include retired batteries.

[0036] In the containerized energy storage system, the control module 14 can be connected to each sub-box 12 and the fire protection module 13 respectively.

[0037] In the container-type energy storage system, the fire-fighting module 13 can be connected to each sub-box 12 respectively.

[0038] The control module 14 may be configured to respectively obtain preset parameters of each sub-box 12 and determine a target sub-box 12 that requires fire protection among the sub-boxes 12 based on the preset parameters.

[0039] After determining the target sub-box 12 that needs to be fire-fighted among the sub-boxes 12 , the control module 14 can also be used to send a control signal to the fire-fighting module 13 to control the fire-fighting module 13 to perform fire-fighting processing on the target sub-box 12 .

[0040] The fire protection module 13 may be configured to receive a control signal sent by the control module 14 and perform fire protection processing on the target sub-box 12 according to the received control signal.

[0041] In a possible implementation, the fire fighting module 13 may include a water immersion fire fighting submodule, which may be connected to each sub-box 12 respectively and used to fill the target sub-box 12 with water.

[0042] The water immersion fire fighting submodule for flooding the target sub-box 12 has the following advantages: First, since the fire extinguishing medium used by the water immersion fire fighting submodule is water, it is environmentally friendly and meets the needs of green development.

[0043] Secondly, the fire extinguishing effect of flooding the target sub-box 12 with water is better, and it can ensure that the target sub-box 12 will not re-ignite as much as possible.

[0044] In a possible implementation, the water immersion fire fighting submodule may include a water storage tank, a circulation pump, and a sprinkler unit.

[0045] In the water immersion fire fighting sub-module, the circulation pump can be connected to the water storage tank and the sprinkler unit respectively, and the sprinkler unit can be connected to each sub-box 12 respectively.

[0046] Water tanks can be used to store water.

[0047] The circulation pump can be used to transfer the water in the water storage tank to the spray unit when the target sub-box 12 needs to be irrigated.

[0048] The spray unit can be used to irrigate the target sub-box 12 with water.

[0049] In a possible implementation, the fire fighting module 13 may further include a gas fire fighting submodule.

[0050] The gas fire fighting submodule 132 may be connected to each sub-box 12 respectively, and the gas fire fighting submodule 132 may be used to release fire fighting gas to the target sub-box 12 .

[0051] Exemplarily, the firefighting gas may be perfluorohexanone.

[0052] In the embodiment of the present application, since each sub-box 12 is sealed, after the water immersion fire fighting sub-module 131 fills the target sub-box 12 with water, the target sub-box 12 can prevent water from flowing to other sub-boxes 12. Therefore, when a fire occurs in some energy storage batteries in the target sub-box 12, it can avoid affecting some energy storage batteries in other sub-boxes 12.

[0053] Similarly, since each sub-box 12 is sealed, after the gas fire fighting sub-module releases the fire fighting gas to the target sub-box 12, the target sub-box 12 can prevent the fire fighting gas from reaching other sub-boxes 12, thereby avoiding affecting some energy storage batteries in other sub-boxes 12 when a fire occurs in some energy storage batteries in the target sub-box 12.

[0054] From the above, it can be seen that the container-type energy storage system of the embodiment of the present application is provided with several sealed sub-boxes, fire protection modules and control modules in the main box. Each sub-box includes several energy storage batteries. The control module is connected to each sub-box and the fire protection module. The fire protection module is connected to each sub-box respectively. The preset parameters of each sub-box are obtained through the control module. According to the preset parameters, the target sub-box that needs to be extinguished in each sub-box is determined, and the target sub-box is subjected to fire protection treatment through the fire protection module. By using the container-type energy storage system provided by the present application, the impact of a fire in some energy storage batteries on other energy storage batteries can be minimized, thereby improving the reuse efficiency of retired batteries.

[0055] In one possible implementation, the control module 14 may include a smoke sensor, a combustible gas sensor, an ambient temperature sensor, and a control unit.

[0056] The smoke sensor, the combustible gas sensor and the ambient temperature sensor may all be provided in each sub-box 12 , and the smoke sensor, the combustible gas sensor and the ambient temperature sensor may all be connected to the control unit.

[0057] The smoke sensor may be used to detect whether smoke exists in each sub-box 12 , and may send data describing whether smoke exists in the corresponding sub-box 12 to the control unit.

[0058] The combustible gas sensor may be used to detect whether combustible gas exists in each sub-box 12 , and may send data describing whether combustible gas exists in the corresponding sub-box 12 to the control unit.

[0059] In a possible implementation, the combustible gas may include but is not limited to carbon monoxide and hydrogen, and based on this, the combustible gas sensor may include a carbon monoxide sensor and a hydrogen sensor.

[0060] The ambient temperature sensor may be used to detect the ambient temperature in each sub-box 12 and may send data describing the ambient temperature in the corresponding sub-box 12 to the control unit.

[0061] The control unit can receive data sent by the smoke sensor, the combustible gas sensor and the ambient temperature sensor respectively, and after receiving the data sent by the smoke sensor, the combustible gas sensor and the ambient temperature sensor, determine the target sub-box 12 according to the data sent by the smoke sensor, the combustible gas sensor and the ambient temperature sensor.

[0062] In a possible implementation, the control module 14 may further include a battery management unit, wherein the battery management unit may be connected to each energy storage battery in each sub-box 12 respectively, and the battery management unit may also be connected to the control unit.

[0063] The battery management unit may be used to obtain preset parameters of each energy storage battery and may send the preset parameters of each energy storage battery to the control unit.

[0064] Exemplarily, the preset parameters may include but are not limited to voltage, current, and battery temperature, etc. Based on this, the battery management unit can be used to obtain the voltage, current, and battery temperature of each energy storage battery, and can send the voltage, current, and battery temperature of each energy storage battery to the control unit.

[0065] The control unit may also be configured to determine the target sub-box 12 based on the preset parameters of each energy storage battery sent by the battery management unit.

[0066] In an embodiment of the present application, the control unit can determine the target sub-box 12 based on the data sent by the smoke sensor, the combustible gas sensor and the ambient temperature sensor, combined with the preset parameters of each energy storage battery sent by the battery management unit.

[0067] In one possible implementation, the containerized energy storage system may further include an audible and visual alarm.

[0068] The sound and light alarm may be connected to the control module 14 . Specifically, the sound and light alarm may be connected to the control unit in the control module 14 . In addition, the sound and light alarm may be arranged on the main box 11 .

[0069] The sound and light alarm device can be used to receive the alarm signal sent by the control unit in the control module 14, and output the sound and light alarm signal after receiving the alarm signal.

[0070] In a possible implementation, the containerized energy storage system may further include a monitoring unit.

[0071] The monitoring unit may be connected to each sub-box 12 respectively.

[0072] The monitoring unit may be used to obtain real-time images in each sub-box 12 and send the real-time images in each sub-box 12 to the user.

[0073] The following combination Figure 1 , the working mode of the containerized energy storage system provided in the embodiment of the present application is exemplified:

[0074] During the operation of the containerized energy storage system, the control unit can determine the target sub-box 12 where a fire may occur based on the data sent by the smoke sensor, combustible gas sensor and ambient temperature sensor, as well as the preset parameters of each energy storage battery sent by the battery management unit.

[0075] After determining the target sub-box 12, the control unit may first control the gas fire fighting sub-module to release fire fighting gas to the target sub-box 12. The control unit may also output an audible and visual alarm signal to the user through the audible and visual alarm.

[0076] After receiving the sound and light alarm signal, the user can determine whether it is necessary to flood the target sub-box 12 with water through the water immersion fire fighting sub-module based on the real-time image of the target sub-box 12 sent by the monitoring unit.

[0077] If the user determines that the target sub-box 12 needs to be flooded with water by the water immersion fire fighting sub-module, the user can send a water flooding signal to the control unit to instruct the control unit to control the water immersion fire fighting sub-module to flood the target sub-box 12 with water.

[0078] In addition, the control unit can also obtain the real-time image of the target sub-box 12 output by the monitoring unit. Afterwards, the control unit can determine whether it is necessary to irrigate the target sub-box 12 through the water immersion fire fighting sub-module based on the real-time image of the target sub-box 12.

[0079] If the control unit determines that the target sub-box 12 needs to be flooded with water by the water immersion fire fighting sub-module, the control unit may control the water immersion fire fighting sub-module to flood the target sub-box 12 with water.
