Description

Technical Field

[0001] This invention relates to the field of energy storage system technology, and more specifically, to a fire protection system and control method for an energy storage container. Background Technology

[0002] In recent years, with the rapid development of energy storage technology, energy storage containers have been widely used in fields such as grid balancing and emergency backup power. However, the fire sprinklers inside existing energy storage containers are generally installed on the top of the container, which has little effect on controlling long-distance, single-point fires and cannot effectively extinguish and cool down the fire when the battery pack experiences thermal runaway, thus failing to meet fire protection requirements. This poses a serious challenge to the reliability and safety of energy storage containers. Summary of the Invention

[0003] In view of this, the present invention aims to propose a fire protection system and control method for energy storage containers to solve the problem that the prior art cannot effectively extinguish and cool down the fire when the battery pack experiences thermal runaway.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] A fire protection system for an energy storage container, comprising:

[0006] An energy storage container is provided with multiple battery clusters inside, each battery cluster includes multiple battery packs, each battery pack includes multiple battery cells, and the side wall of the energy storage container is provided with an automatic roller shutter door that can be automatically opened or closed for installing and removing battery packs.

[0007] The detection device is used to detect the status information of individual battery cells in real time.

[0008] Firefighting robots are used to remove abnormal battery packs from energy storage containers and transport them to designated locations. During the transport process, they can also extinguish and cool down battery packs that have experienced thermal runaway.

[0009] The control device, based on the status information fed back by the detection device, controls the working status of the fire-fighting robot and the automatic roller shutter door, and removes the abnormal battery pack.

[0010] The fire protection system of the energy storage container described in this application can promptly remove the abnormal battery pack and place it in a safe location when any battery pack in the energy storage container experiences thermal runaway, thereby preventing the fire from spreading inside the energy storage container.

[0011] Furthermore, the detection device includes a detection unit, a judgment unit, and a storage unit. The detection unit includes a current detection probe, a voltage detection probe, a temperature detection probe, a pressure detection probe, and a gas concentration detection probe. The current detection probe and the voltage detection probe are disposed on the surface of the battery cell and are used to detect the input / output current value and voltage value of the battery cell, respectively. The temperature detection probe, the pressure detection probe, and the gas concentration detection probe are disposed inside the battery cell and are used to detect the temperature value, pressure value, and gas concentration value inside the battery cell, respectively.

[0012] The judgment unit includes a current judgment unit, a voltage judgment unit, a temperature judgment unit, a pressure judgment unit, and a gas concentration judgment unit. The current judgment unit is used to judge the relationship between the input / output current value and the current setting value of the battery cell; the voltage judgment unit is used to judge the relationship between the input / output voltage value and the voltage setting value of the battery cell; the temperature judgment unit is used to judge the relationship between the temperature value and the temperature setting value of the battery cell; the pressure judgment unit is used to judge the relationship between the pressure value and the pressure setting value of the battery cell; and the gas concentration judgment unit is used to judge the relationship between the gas concentration value and the gas concentration setting value of the battery cell.

[0013] The storage unit is used to store the status values ​​and settings of individual battery cells.

[0014] This setup facilitates real-time monitoring of changes in temperature, pressure, and gas concentration within individual battery cells. It enables the timely detection of abnormal battery cells and allows for the implementation of safety measures before thermal runaway occurs, preventing the corresponding battery pack from experiencing thermal runaway and causing a fire.

[0015] Furthermore, the firefighting robot includes: a main body, the lower part of which is provided with a power chassis, the power chassis being used to drive the firefighting robot to move and to provide power to other components;

[0016] The front end of the main body is provided with a conveying device, which is used to lift and carry the battery pack.

[0017] The handling device is equipped with a fire-fighting device, which is used to extinguish and cool down abnormal battery packs during the handling process.

[0018] The main body is also equipped with a sensing device, a navigation device, a communication device, and a controller. The sensing device is used to detect the status information of the surrounding environment in real time and identify abnormal battery packs. The navigation device plans the movement path of the fire-fighting robot based on real-time satellite map information and status information fed back by the sensing device. The communication device is used to receive instructions from the control center and send working status information to the control center. The controller controls the working status of the power chassis, the handling device, and the fire-fighting device based on the information fed back by the communication device, the sensing device, and the navigation device, and handles abnormal battery packs for handling and fire extinguishing and cooling.

[0019] Firefighting robots can promptly remove abnormal battery packs and move them to designated locations to prevent the fire from spreading.

[0020] Furthermore, the sensing device includes a temperature sensor, a smoke sensor, an optical camera, and a laser rangefinder. The temperature sensor is used to detect the temperature of the battery pack and locate abnormal battery packs. The smoke sensor is used to detect the smoke concentration information of the surrounding environment and assist in locating abnormal battery packs. The optical camera is used to send real-time video information of the scene to the control center and assist the control center in remotely controlling the fire-fighting robot. The laser rangefinder is used to detect the distance between the fire-fighting robot and surrounding objects in real time and assist the navigation device in planning the movement path of the fire-fighting robot.

[0021] This setup allows firefighting robots to move quickly, promptly remove abnormal battery packs, and transport them to designated locations, reducing the probability of fire spreading.

[0022] Furthermore, the battery pack is equipped with a self-locking device, which is used to fix the battery pack and the support frame inside the energy storage container together, and the self-locking device can automatically unlock and lock under the control of the control device.

[0023] This setup facilitates the automated disassembly and transport of abnormal battery packs by firefighting robots, greatly improving work efficiency.

[0024] Furthermore, it also includes magnetic terminal blocks, which include male and female connectors that are magnetically connected together. The battery pack has terminals on its side wall, which are inclined on the side wall. The female connector is located on the terminals, and the male connector is connected to other battery packs via wires.

[0025] This setup facilitates automated disassembly of the battery pack, improving disassembly efficiency.

[0026] Furthermore, a control method for an energy storage container fire protection system, employing the aforementioned energy storage container fire protection system, includes the following steps:

[0027] Step 1: The fire protection system is activated, and the status values ​​of each battery cell are monitored in real time. The control mode information is obtained based on the alarm status range where the difference between the status value and the set value lies.

[0028] Step 2: Adjust the working status of automatic rolling shutters, fire robots and self-locking devices in the fire protection system according to the control mode information, and at the same time control abnormal battery packs to go offline;

[0029] Among them, the state values ​​include T 温度 p 压力 Q 浓度 I 电流 and U 电压 The settings include T 设定 p 设定 Q 设定 I 设定 and U 设定 T 温度 p is the internal temperature value of a single battery cell. 压力 Q represents the internal pressure value of a single battery cell. 浓度 I represents the internal gas concentration value of a single battery cell. 电流 U represents the input / output current value of a single battery cell. 电压 T represents the input / output voltage value of a single battery cell. 设定 The internal temperature value of the battery cell set by the user, p 设定 The internal pressure value of a single battery cell set by the user, Q 设定 The internal gas concentration value of the battery cell set by the user, I 设定 The current value of a single battery cell set by the user, U 设定 The voltage value of a single battery cell set by the user.

[0030] This control method can quickly and accurately locate abnormal battery packs and take appropriate isolation and fire extinguishing measures to prevent fires from occurring inside the energy storage container.

[0031] Furthermore, in step 1, when the difference between the state value of a battery cell and the set value is detected to be within the first alarm range, control mode A is executed;

[0032] When the difference between the state value of a battery cell and the set value is detected to be within the second alarm range, control mode B is executed;

[0033] The first alarm interval is set as follows: when T b >T 温度 -T 设定≥T a 、 or P b >P 压力 -P 设定 ≥P a 、 or Q b >Q 浓度 -Q 设定 ≥Q a 、 or I b >I 电流 -I 设定 ≥I a 、 or U b >U 电压 -U 设定 ≥U a Any one of the following is true and lasts for a duration of t1;

[0034] The second alarm interval is set as follows: when T c >T 温度 -T 设定 ≥T b 、 or P c >P 压力 -P 设定 ≥P b 、 or Q c >Q 浓度 -Q 设定 ≥Q b 、 or I c >I 电流 -I 设定 ≥I b 、 or U c >U 电压 -U 设定 ≥U b Any one of the following is true and lasts for a duration of t1;

[0035] T a T b and T c To separate the internal temperature value T of the battery cell 温度 With the set temperature value T 设定 Temperature threshold P for the interval containing the difference a P b and P c To separate the internal pressure value P of the battery cell 压力 With the set pressure value P 设定 The pressure threshold Q in the interval containing the difference a Q b and Q c To separate the internal gas concentration value Q of the battery cell 浓度 With the set gas concentration value Q 设定 The gas concentration threshold within the range of the difference, I a I band I c To separate the input / output current values ​​I of individual battery cells 电流 With the set current value I 设定 The current threshold value, U, within the range of the difference. a U b and U c To separate the input / output voltage values ​​U of individual battery cells 电压 With the set voltage value U 设定 The voltage threshold of the interval containing the difference.

[0036] This control method can take corresponding safety management measures according to the status of the battery pack, which can not only maintain the normal operation of the energy storage container to the maximum extent, but also minimize safety risks.

[0037] Furthermore, when the system is in the first alarm range, it enters control mode A and executes the following steps:

[0038] A1: Remove the abnormal battery cell from the production line and proceed to A2;

[0039] A2: Continuously monitor abnormal battery cells. Once the parameters of the abnormal battery cell return to normal, bring the corresponding battery cell back online.

[0040] This control method can isolate abnormal battery cells in a timely manner, improving the safety of system operation.

[0041] Furthermore, when the system is in the second alarm zone, it enters control mode B and executes the following steps:

[0042] B1: Remove the corresponding battery pack from the production line and proceed to B2;

[0043] B2: Open the automatic rolling door of the energy storage container, and at the same time start the fire-fighting robot to take out the corresponding battery pack and move it to the designated location.

[0044] This control method can remove the battery pack from the energy storage container and move it to a safe location when an anomaly occurs, thus preventing a fire inside the energy storage container.

[0045] Compared with the prior art, the fire protection system and control method of the energy storage container described in this invention have the following advantages: when any battery pack in the energy storage container experiences thermal runaway, the abnormal battery pack can be removed in time and placed in a safe location, thus preventing the fire from spreading inside the energy storage container.

The automatic roller shutter door 11 can be automatically opened or closed for installing and removing battery packs 100.

[0068] The detection device is used to detect the status information of individual battery cells in real time.

[0069] Firefighting robot 2 is used to remove abnormal battery pack 100 from energy storage container 1 and transport it to a set location. During the transportation process, it can extinguish and cool down the battery pack 100 that has thermal runaway.

[0070] The control device, based on the status information fed back by the detection device, controls the working status of the fire robot 2 and the automatic roller shutter door 11 to remove the abnormal battery pack 100.

[0071] The fire protection system of the energy storage container described in this application can promptly remove the abnormal battery pack 100 and place it in a safe location when any battery pack 100 in the energy storage container 1 experiences thermal runaway, thereby preventing the fire from spreading inside the energy storage container 1.

[0072] As a preferred example of the present invention, the detection device includes a detection unit, a judgment unit, and a storage unit. The detection unit includes a current detection probe, a voltage detection probe, a temperature detection probe, a pressure detection probe, and a gas concentration detection probe. The current detection probe and the voltage detection probe are disposed on the surface of the battery cell and are used to detect the input / output current value and voltage value of the battery cell, respectively. The temperature detection probe, the pressure detection probe, and the gas concentration detection probe are disposed inside the battery cell and are used to detect the temperature value, pressure value, and gas concentration value inside the battery cell, respectively.

[0073] The judgment unit includes a current judgment unit, a voltage judgment unit, a temperature judgment unit, a pressure judgment unit, and a gas concentration judgment unit.

[0074] The storage unit is used to store the status values ​​and settings of individual battery cells.

[0075] Specifically, this setup facilitates real-time monitoring of changes in temperature, pressure, and gas concentration within individual battery cells, enabling timely detection of abnormal battery cells and allowing for safety measures to be taken before thermal runaway occurs, thus preventing the corresponding battery pack 100 from experiencing thermal runaway and causing a fire.

[0076] A control method for a fire protection system of an energy storage container, employing the fire protection system of the energy storage container 1 described above, is characterized by comprising the following steps:

[0077] Step 1: The fire protection system is activated, and the status values ​​of each battery cell are monitored in real time. The control mode information is obtained based on the alarm status range where the difference between the status value and the set value lies.

[0078] Step 2: Adjust the working status of the automatic rolling shutter door 11, fire robot 2 and self-locking device 3 in the fire protection system according to the control mode information, and at the same time control the abnormal battery pack 100 to go offline;

[0079] Among them, the state values ​​include T 温度 p 压力 Q 浓度 I 电流 and U 电压 The settings include T 设定 p 设定 Q 设定 I 设定 and U 设定 T 温度 p is the internal temperature value of a single battery cell. 压力 Q represents the internal pressure value of a single battery cell. 浓度 I represents the internal gas concentration value of a single battery cell. 电流 U represents the input / output current value of a single battery cell. 电压 T represents the input / output voltage value of a single battery cell. 设定 The internal temperature value of the battery cell set by the user, p 设定 The internal pressure value of a single battery cell set by the user, Q 设定 The internal gas concentration value of the battery cell set by the user, I 设定 The current value of a single battery cell set by the user, U 设定 The voltage value of a single battery cell set by the user.

[0080] Specifically, this control method can quickly and accurately locate abnormal battery packs 100 and take corresponding isolation and fire extinguishing measures for the corresponding battery packs 100 to prevent fires from occurring inside the energy storage container 1.

[0081] As a preferred example of the present invention, in step 1, when the difference between the state value of a battery cell and the set value is detected to be within the first alarm range, control mode A is executed;

[0082] When the difference between the state value of a battery cell and the set value is detected to be within the second alarm range, control mode B is executed;

[0083] The first alarm interval is set as follows: when T b >T 温度 -T 设定 ≥T a 、 or P b >P 压力 -P 设定 ≥P a 、 or Q b >Q 浓度 -Q 设定 ≥Qa 、 or I b >I 电流 -I 设定 ≥I a 、 or U b >U 电压 -U 设定 ≥U a Any one of the following is true and lasts for a duration of t1;

[0086] Specifically, this control method can take corresponding safety management measures according to the status of the battery pack 100, which can both maximize the normal operation of the energy storage container 1 and minimize safety risks.

[0087] As a preferred example of the present invention, when the system is in the first alarm range, the energy storage system enters control mode A and performs the following steps:

[0088] A1: Remove the abnormal battery cell from the production line and proceed to A2;

[0089] A2: Continuously monitor abnormal battery cells. Once the parameters of the abnormal battery cell return to normal, bring the corresponding battery cell back online.

[0090] Specifically, this control method can isolate abnormal battery cells in a timely manner, improving the safety of system operation.

[0091] Preferably, this application employs a dynamically reconfigurable battery system, which enables any single battery cell to be offline or online. The dynamically reconfigurable battery system is existing technology and will not be described in detail here.

This setting facilitates the fire-fighting robot 2 to automatically disassemble and transport the abnormal battery pack 100, greatly improving work efficiency.

[0113] Specifically, when the fire-fighting robot 2 disassembles and moves the abnormal battery pack 100, the magnetic terminal block on the battery pack 100 will be disconnected by force. This setting facilitates the automated disassembly of the battery pack 100 and improves disassembly efficiency.

[0114] As a preferred example of the present invention, the female connector 42 is provided with a mounting groove 420, and a female conductor 421 is provided at the bottom of the mounting groove 420.

[0116] As a preferred example of the present invention, the female connector 42 is provided with a first magnet 422, which is disposed at the bottom of the mounting groove 420 for magnetic connection with the male connector 41.

[0117] This configuration facilitates magnetic connection between the female connector 42 and the male connector 41.

[0123] As a preferred example of the present invention, the female conductor 421 is provided with a receiving groove 423 for receiving the male conductor 411.

[0124] This arrangement allows for sufficient contact between the male conductor 411 and the female conductor 421, thereby improving conductivity.

[0125] As a preferred example of the present invention, the side wall of the mounting groove 420 is provided with a slot 424, and the side wall of the male connector 41 is provided with a protrusion 413. The protrusion 413 and the slot 424 cooperate to engage and fix the male connector 41 and the female connector 42 together.

[0126] This configuration enhances the robustness of the connection between the male connector 41 and the female connector 42.

[0127] As a preferred example of the present invention, the side wall of the male connector 41 is provided with a second magnet 412, and the side wall of the mounting groove 420 is provided with a first magnet 422.
