[0040] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0041] Embodiment 1

[0042] Please refer to the drawings Figure 1 - the drawings Figure 3 The energy storage device of the present application comprises a power module 1, a dehumidification module 2, a fire-fighting module 3 and a control module 4.

[0043] The power module 1 comprises a first power supply part and a second power supply part which are independently output. Specifically, the first power supply part and the second power supply part are both DC 24V.

[0044] The dehumidification module 2 is electrically connected with the first power supply part, so that the first power supply part supplies power for the dehumidification module 2.

[0045] The fire-fighting module 3 is electrically connected with the second power supply part, so that the second power supply part supplies power for the fire-fighting module 3.

[0046] The control module 4 is interlocked between the dehumidification module 2 and the fire-fighting module 3, and is used for selectively controlling the opening of the dehumidification module 2 or the fire-fighting module 3.

[0047] The energy storage device in the embodiment adopts the first power supply part to provide power supply for the dehumidification module 2, the second power supply part provides power supply for the fire-fighting module 3, and then through the control module 4, when the fire-fighting module 3 operates, the first power supply part is disconnected with the dehumidification module 2, that is, the dehumidification module 2 stops operating. When the fire-fighting module 3 completes the action, the first power supply part is connected with the dehumidification module 2, that is, the dehumidification module 2 normally operates to perform the dehumidification work. Through the setting, the phenomenon that the dehumidification module 2 and the fire-fighting module 3 start simultaneously can be avoided, and then the load power of the device can be reduced, the operation cost of the device is reduced, and at the same time, it can also ensure that the dehumidification module 2 operates in a reasonable period of time and ensures good dehumidification effect.

[0048] In addition, in the control of the energy storage device, the dehumidification device avoids operating in the spraying process of the fire-fighting module 3, which can effectively avoid the overuse of the dehumidification module 2, correspondingly improve the durability of the dehumidification module 2, and effectively prolong the service life of the dehumidification module 2.

[0049] In some embodiments, the control module 4 includes a relay 41 connected to the dehumidification module 2 and the fire-fighting module 3.

[0050] The specific connection between the fire-fighting module 3, the dehumidification module 2 and the power supply module 1 in the embodiment is that the relay 41 includes a normally closed contact L1 and a control coil RY, the normally closed contact L1 is connected between the first power supply part and the dehumidification module 2, the input end of the control coil RY is connected with the second power supply part, and the output end of the control coil RY is connected with the fire-fighting module 3. After the control coil RY is powered, it is attracted, so that the normally closed contact L1 is disconnected, and the normally open contact is closed.

[0051] The first power supply part includes a first positive terminal V1+ and a first negative terminal V1-; the second power supply part includes a second positive terminal V2+ and a second negative terminal V2-. The fire-fighting module 3 is provided with a control switch DO for controlling the opening and closing of the fire-fighting module 3.

[0052] The first positive terminal V1+ is connected with the positive terminal of the dehumidification module 2, the normally closed contact L1 is connected between the first negative terminal V1- and the negative terminal of the dehumidification module 2; the second positive terminal V2+ is connected with the input end of the control coil RY, the output end of the control coil RY is connected with one side of the control switch DO, the second negative terminal V2- is connected with the other side of the control switch DO, and the second negative terminal V2- is connected with the negative terminal of the fire-fighting module 3.

[0053] Specific operation is that when the energy storage device normally operates, the fire-fighting module 3 is not started, that is, the control switch DO is in a disconnected state, at this time the control coil RY in the dehumidification module 2 cannot be powered, the normally closed contact L1 is still closed to be powered, and the dehumidification module 2 is in a normal power supply mode.

[0054] When the fire-fighting module 3 is in the alarm spraying state, the fire-fighting module 3 is started, at this time, the control switch DO is in the closed state, the control coil RY of the relay 41 is powered and attracted, at this time, the normally closed contact L1 is switched to the open state, the dehumidification module 2 is in the power-off state and cannot work normally, so as to ensure that the dehumidifier cannot work simultaneously with the fire-fighting spraying, and effectively reduce the load power of the system.

[0055] When the fire-fighting module 3 is in the alarm spraying state, the fire-fighting module 3 is started, at this time, the control switch DO is in the closed state, the control coil RY of the relay 41 is powered and attracted, at this time, the normally closed contact L1 is switched to the open state, the dehumidification module 2 is in the power-off state and cannot work normally, so as to ensure that the dehumidifier cannot work simultaneously with the fire-fighting spraying, and effectively reduce the load power of the system.

[0056] Through the above setting, the overall circuit design is reasonable and simple, the existing circuit can be improved, the operation and maintenance are simple and convenient, the function is practical, the fire-fighting module 3 and the dehumidification module 2 cannot work simultaneously, the load power of the equipment is effectively reduced, and the operation cost is reduced.

[0057] Embodiment 2:

[0058] The difference between this embodiment and embodiment 1 is that, please refer to Figures 4-6 The control module 4 of this embodiment includes a relay 41 and a battery manager BMS, the input pipe of the battery manager BMS is connected with the fire-fighting module 3, the output end of the battery manager BMS is connected with the relay 41, and the relay 41 is connected with the dehumidification module 2.

[0059] The specific connection between the fire-fighting module 3, the dehumidification module 2 and the power module 1 in this embodiment is as follows:

[0060] The relay 41 includes a normally closed contact L1 and a control coil RY, the normally closed contact L1 is connected between the first power supply part and the dehumidification module 2, the control coil RY is connected with the output end of the battery manager BMS, and the input end of the battery manager BMS is connected with the fire-fighting module 3.

[0061] The first power supply part includes a first positive end V1+ and a first negative end V1-, and the second power supply part includes a second positive end V2+ and a second negative end V2-. The fire-fighting module 3 is provided with a control switch DO, which is used to control the opening and closing of the fire-fighting module 3. The battery manager BMS is provided with a spraying ON end, a spraying COM end, a positive output end OUT+ and a negative output end OUT-.

[0062] The first positive terminal V1+ is connected to the positive terminal of the dehumidification module 2, and the normally closed contact L1 is connected between the first negative terminal V1- and the negative terminal of the dehumidification module 2; the input terminal of the control coil RY is connected to the positive output terminal OUT+, the output terminal of the control coil RY is connected to the negative output terminal OUT-, the spray COM terminal is connected to one end of the control switch DO, and the spray ON terminal is connected to the other end of the control switch DO; the second positive terminal V2+ is connected to the positive terminal of the fire protection module 3, and the second negative terminal V2- is connected to the negative terminal of the fire protection module 3.

[0063] Specifically, the operation is as follows: When the energy storage device is working normally, the fire protection module 3 is not activated, and its control switch DO is in the open state. At this time, the normally closed contact L1 of the relay 41 is in the normally closed state, and the dehumidification module 2 is in normal power supply operation.

[0064] When the fire alarm module 3 triggers an alarm, it activates. At this time, the control switch DO closes, outputting a dry contact signal to the spray ON and spray COM terminals of the battery management system (BMS). When the BMS receives the dry contact signal from the control switch DO, it determines that the fire alarm module 3 has started. Simultaneously, it outputs 24V power to the control coil RY of relay 41 through the positive output terminal OUT+ and the negative output terminal OUT-. The control coil RY of relay 41 is energized and engages, causing the normally closed contact L1 to open. The dehumidifier module 2 is de-energized and cannot operate normally, thus ensuring that the dehumidifier does not operate simultaneously with the fire alarm, reducing the system's load power.

[0065] When fire-fighting module 3 finishes spraying, its control switch DO is disconnected. The spray ON and spray COM terminals of the battery management system (BMS) receive a dry contact signal and release, disconnecting the power supply from the positive output terminal OUT+ and the negative output terminal OUT- to relay 41. The control coil RY of relay 41 is de-energized, and its normally closed contact L1 is in the normally closed state. Dehumidification module 2 is then re-energized and resumes normal operation.

[0066] This embodiment uses a battery module to control the dehumidification module 2. Similarly, the control strategy of the battery module can be used to simultaneously control the fire suppression module 3 to prevent it from operating at the same time, further reducing the system's load power and lowering equipment operating costs. Furthermore, this control method features a clever and simplified structural design, facilitating widespread application.

[0067] Example 3:

[0068] This embodiment is based on the above embodiment; please refer to [link / reference]. Figure 7 It provides energy storage systems, including energy storage devices as described above.

[0069] The energy storage system in the embodiment can effectively avoid the simultaneous operation of the fire-fighting module 3 and the dehumidification module 2, reduce the load power of the energy storage system, and further reduce the operation cost.

[0070] Moreover, since the dehumidification module 2 is not operated during the operation of the fire-fighting module 3, the dehumidification module 2 can be ensured to be operated at a suitable time period, the dehumidification effect is effectively ensured, and the service life of the dehumidification module 2 can be correspondingly prolonged.
