Description

Technical Field

[0001] The present invention relates to the technical field of containerized battery pack energy storage equipment, and in particular to a battery fire prevention system and a control method for an energy storage container. Background Art

[0002] With the development of the economy, my country's electricity demand has grown strongly, but energy generation based on wind and solar energy is greatly affected by geography and weather, and is indirect and volatile. When connected to the grid, a large-scale energy storage system is needed to regulate and control the quality of electricity. Energy storage containers have the advantages of high capacity, high reliability, high flexibility, and strong environmental adaptability. They have begun to be widely used on the power generation side, grid side, and user side of the power system. They have played an important role in helping the grid regulate power transmission and distribution, achieve peak shaving and valley filling, voltage and frequency regulation, alleviate grid congestion, and ensure load power consumption.

[0003] When a cell or battery module of an existing energy storage container fire protection system experiences thermal runaway, the main consideration is to use fire protection measures inside the container, which requires high system complexity and cannot reliably block the spread of heat. In extreme cases, a single cell may even experience thermal runaway, causing the entire box of batteries to burn.

[0004] Therefore, it is necessary to provide a device that can physically separate the battery pack that has thermal runaway, separate the battery cell or module with temperature runaway from the container, and suppress the spread of thermal runaway.

[0005] And because batteries burn very quickly, the control method of the fire protection system in the energy storage container also needs to be greatly changed;

[0006] The above-mentioned design of the energy storage container, its fire prevention and control system basically follows the fire protection design scheme of traditional buildings. In terms of the applicability of fire safety warning, there are three major drawbacks: First, in the detection part, the existing energy storage fire protection mainly uses the smoke temperature sensitivity as the basis for judging whether a fire has occurred. The detection quantity is relatively single, which will cause the battery to be completely thermally runaway. The generated temperature and smoke can only play an alarm role when it spreads to the entire cabin, and the fire signal cannot be detected at an early stage; secondly, in the fire suppression part, the existing energy storage fire protection mostly uses aerosols, dry powders, heptafluoropropane, etc. as fire extinguishing agents. Conventional spraying cannot work again after one spray, and can only extinguish the open flame for the first time, but cannot solve the problem of battery re-ignition, and cannot completely improve the thermal runaway phenomenon of the battery; finally, in the fire control strategy part, the existing energy storage fire control logic is either too simple or too complex, which can easily cause the battery to fail to operate after thermal runaway is triggered or to malfunction when the battery is working normally.

[0007] Therefore, in the face of the above-mentioned technical problems, how to provide a battery discharge system and fire warning control method suitable for energy storage containers, so as to achieve joint monitoring of smoke temperature sensitivity and multiple combustible gases, discharge the fire battery separately, give graded warnings, and perform linkage control, so as to achieve accurate detection of thermal runaway characteristic quantities, discharge the battery in time, and quickly cool down, has become an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0008] Therefore, the present invention is made in view of the above problems. The purpose of the present invention is to monitor the battery using a three-level alarm system, and to deal with the high-temperature battery pack in time when the third-level alarm occurs.

[0072] Embodiment 2

[0073] This embodiment provides a battery fire warning control method for an energy storage container as described in Embodiment 1.

[0074] Step S1: Acquire monitoring signals from various detectors. When the temperature sensor detects that the characteristic quantity of battery thermal runaway exceeds the standard, trigger a first-level alarm and take a first-level firefighting action. The first-level firefighting action is: upload the alarm information, battery parameters, and location information to the monitoring platform of the fire control room through the control cabinet and focus on displaying the relevant exceeding parameters on the local display and control unit;

[0075] Step S2: Continuously obtain monitoring signals from each detector. When the temperature sensor and the gas sensor detect that the characteristic quantity of battery thermal runaway continues to exceed the standard, a secondary alarm is triggered and a secondary firefighting action is taken. The secondary firefighting action is: the control cabinet is started, the air conditioning system quickly discharges the combustible gas in the battery compartment out of the box, and the BMS and PCS are linked to cut off the power of the dangerous battery, and the remaining batteries are reduced in power to limit the discharge power output or charging power input, and the hydraulic cylinder 15 and the hydraulic rod 152 are controlled to move so that the rotating plate 16 rotates with the rotating shaft 161 as the axis, and the sealing plate is controlled to move into the hydraulic sliding groove 172, and the hydraulic cylinder 2 18 is controlled to drive the explosion-proof plate to shrink and open the channel;

[0076] Step S3: Continuously obtain the monitoring signals of each detector. On the basis of maintaining the triggering of the second-level alarm, if the battery thermal runaway continues to escalate, the third-level alarm is triggered and the third-level firefighting action is taken. Among them, the third-level firefighting action is: the control cabinet controls the BMS to disconnect the circuit, the PCS is shut down, all batteries are powered off, the sound and light alarm 143 is started, and the electric push rod 68 on the layer where the out-of-control battery pack 60 is located is controlled to retract, and the lifting plate 65 is rotated and lifted with the rotating shaft 2 655 as the axis through the external expansion plate 652 and the external expansion plate 653, so that the battery pack 60 and the screw 601 move together, and the screw 601 will drive the arc-shaped slide plate 66 to move together. The gear 671 meshes with the rack 632, which causes the rotating ring 67 to rotate. The rotation of the rotating ring 67 will discharge the screw 601 through the inner screw hole 672, thereby disengaging the battery pack 60. The battery pack 60 will slide on the roller 2 654 to the rotating plate 16, and then the roller 1 163 on the rotating plate 16 will slide into the slide-out groove 133, the hydraulic sliding groove 172 will retract the sealing plate 173, the hydraulic cylinder 2 18 will retract the explosion-proof plate 181, and the battery pack 60 will enter the bottom opening 111 from the sliding opening 123, and enter the explosion-proof groove 113 along the internal slide 112. The control cabinet 30 controls the fire cabinet 40 to continuously inject perfluorohexanone into the explosion-proof groove 113;

[0077] Step S4: Control the electric push rod 68, the hydraulic cylinder 1 15, and the hydraulic cylinder 2 18 to return to their original positions, so that the rotating plate, the sealing plate, and the explosion-proof plate return to their original positions, and the explosion-proof groove is sealed.

10. A battery fire warning control method for an energy storage container, characterized in that: A battery fire warning processing system for an energy storage container according to any one of claims 1 to 9, comprising the following steps: S1: Acquire monitoring signals from various detectors. When the temperature sensor detects that the characteristic quantity of battery thermal runaway exceeds the standard, trigger a first-level alarm and take a first-level firefighting action. The first-level firefighting action is: upload the alarm information, battery parameters, and location information to the monitoring platform of the fire control room through the control cabinet (30) and focus on displaying the relevant exceeding parameters on the local display and control unit; S2: Continuously obtain monitoring signals from each detector. When the temperature sensor and the gas sensor detect that the characteristic quantity of battery thermal runaway continues to exceed the standard, a second-level alarm is triggered and a second-level firefighting action is taken. The second-level firefighting action is: the control cabinet (30) is started, the air conditioning system quickly discharges the combustible gas in the battery compartment out of the box, and the BMS and PCS are linked to cut off the power of the dangerous battery, and the power of the remaining batteries is reduced to limit the discharge power output or charging power input, and the hydraulic cylinder 1 (15) and the hydraulic rod (152) are controlled to move so that the rotating plate (16) rotates around the rotating shaft (161) as the axis, and the sealing plate is controlled to move into the hydraulic sliding groove (172). The second hydraulic cylinder (18) is controlled to drive the explosion-proof plate (181) to contract and open the channel; S3: Continuously obtain the monitoring signals of each detector. On the basis of maintaining the triggering of the second-level alarm, if the battery thermal runaway continues to escalate, the third-level alarm is triggered and the third-level firefighting action is taken. Among them, the third-level firefighting action is: the control cabinet (30) controls the BMS to disconnect the circuit, the PCS is shut down, all batteries are powered off, the sound and light alarm (143) is started, and the electric push rod (68) on the layer where the out-of-control battery pack (60) is located is controlled to retract, and the lifting plate (65) is rotated and lifted with the second rotating shaft (655) as the axis through the external expansion plate (652) and the external expansion plate (653), so that the battery pack (60) and the screw (601) move together, and the screw (601) drives the arc-shaped slide plate (66) to move together. Due to the gear (671) and the rack (63 2) engagement, which causes the rotating ring (67) to rotate. The rotation of the rotating ring (67) discharges the screw (601) through the inner screw hole (672), thereby causing the battery pack (60) to detach. The battery pack (60) slides on the second roller (654) to the rotating plate (16), and then slides on the first roller (163) on the rotating plate (16) to the slide-out groove (133). The hydraulic sliding groove (172) retracts the sealing plate (173), and the second hydraulic cylinder (18) retracts the explosion-proof plate (181). The battery pack (60) enters the bottom opening (111) from the sliding opening (123), and enters the explosion-proof groove (113) along the internal slideway (112). The control cabinet (30) controls the fire cabinet (40) to continuously inject perfluorohexanone into the explosion-proof groove (113); S4: Control the electric push rod (68), hydraulic cylinder 1 (15), and hydraulic cylinder 2 (18) to return to their original positions, so that the rotating plate, the sealing plate, and the explosion-proof plate (181) return to their original positions, and the explosion-proof groove is sealed.
