Description

Technical Field

[0001] This application relates to the field of battery thermal management technology, specifically to a wake-up device, a wake-up control method, a storage medium, an energy storage system, and an electrical device. Background Technology

[0002] Thermal runaway is a serious safety malfunction in battery systems. When a battery triggers thermal runaway, it instantly generates a large amount of high-temperature gas and heat, causing a sharp increase in internal pressure and temperature of the battery pack. If the high temperature and flame cannot be effectively isolated, it can trigger a chain reaction of thermal runaway reactions in adjacent batteries, i.e., heat propagation, which may eventually lead to a fire and explosion of the entire battery pack.

[0003] The Battery Management System (BMS) collects signals such as voltage, temperature, and pressure in real time when the vehicle is running (operating state) to determine if thermal runaway has occurred. However, when the vehicle is parked and the engine is off, the BMS enters a sleep mode to conserve power. In this state, most of the BMS's detection functions are disabled. If thermal runaway occurs at this time, the BMS cannot detect it and be woken up, thus failing to perform the corresponding fault operations.

[0004] In related technologies, BMS wake-up relies on an electronic wake-up signal emitted by a sensor, which has low reliability. Summary of the Invention

[0005] This application provides a wake-up device, a wake-up control method, a storage medium, an energy storage system, and an electrical device, which improves the reliability of wake-up BMS and at least partially solves the above-mentioned technical problems.

[0006] To achieve the above objectives, according to a first aspect of this application, a wake-up device is provided, connected between a wake-up power supply and a device to be woken up; the wake-up device includes: The valve is configured to have a first valve opening degree; and The power supply wake-up device is configured to have a conducting state that enables the wake-up power supply and the device to be woken up to interact electrically; The valve is connected between the wake-up power supply and the power supply wake-up device. When the valve is in the first valve opening position, the power supply wake-up device is in the conducting state to wake up the device to be woken up and execute the preset function.

[0007] The technical solution provided in this application embodiment includes a wake-up device comprising a valve and a power supply wake-up device. The valve is configured with a first valve opening, and the power supply wake-up device is configured to be in a conductive state that enables the wake-up power supply to interact with the device to be woken up. The valve is connected between the wake-up power supply and the power supply wake-up device. When the valve is in the first valve opening, the power supply wake-up device is in a conductive state to wake up the device to execute a preset function. Through the coordinated operation of the valve and the power supply wake-up device, electrical interaction between the wake-up power supply and the device to be woken up is achieved. The mechanical characteristics of the valve enable the conduction of the power supply wake-up device, thereby realizing electrical interaction between the device to be woken up and the wake-up power supply. This eliminates the need for a separate sensor to identify the valve state and transmit sensor signals, effectively reducing the structural complexity of the energy storage system.

[0008] Optionally, the valve is also configured to have a second valve opening degree; Specifically, when the valve is in the second valve opening position, the power supply wake-up device is in the off state, so that the wake-up power supply is disconnected from the device to be woken up.

[0009] By associating the second valve opening degree with the disconnected state of the power supply wake-up device, the power between the wake-up power supply and the device to be woken up can be kept in a state of disconnected power exchange, thus reducing the power consumption of the wake-up power supply.

[0010] Optionally, the power-on wake-up device includes: A first external conductive component is electrically connected to one of the wake-up power supply and the device to be woken up; and The second external conductive component is electrically connected to the wake-up power supply and another of the devices to be woken up. The valve is connected between the first external conductive component and the second external conductive component. When the valve is at the first valve opening degree, the first external conductive component and the second external conductive component are connected through the valve to make the power supply wake-up device in a conductive state; When the valve is in the second valve opening position, the first external conductive component is disconnected from the second external conductive component, so that the power supply wake-up device is in the off state.

[0011] By adopting the above technical solution, the power supply wake-up device is turned on through the physical connection between the first external conductive component, the valve, and the second external conductive component, without relying on sensor signals.

[0012] Optionally, the first valve opening degree includes the maximum opening degree of the valve, and the second valve opening degree includes the minimum opening degree of the valve.

[0013] The first valve opening degree in this embodiment includes the maximum valve opening degree, which refers to the maximum opening degree that the valve can reach after thermal runaway of the battery causes a sharp increase in the internal air pressure of the battery pack. At the maximum opening degree, the first external conductive component and the second external conductive component are electrically connected under the action of the valve, realizing the electrical energy interaction between the wake-up power supply and the device to be woken up. The second valve opening degree in this embodiment includes the minimum valve opening degree, which refers to the valve cover and valve seat being nearly completely sealed or having a small venting gap between them when the battery pack is operating normally (such as driving or charging) or under slight air pressure fluctuations (such as normal venting caused by ambient temperature changes). The first external conductive component and the second external conductive component are disconnected from the electrical connection, enabling disconnected electrical energy interaction between the wake-up power supply and the device to be woken up.

[0014] Optionally, the preset function includes at least one of the following: collecting temperature data of the valve; Collect battery temperature data; collect battery voltage data; collect battery internal pressure data.

[0015] In this embodiment, after the device to be woken up (i.e., the BMS) is woken up, it performs the acquisition of corresponding valve temperature data, battery voltage data, and battery internal pressure data. Then, it uses these data to determine whether the battery has experienced thermal runaway. This method improves the accuracy of determining whether a thermal runaway fault has occurred by not relying on a single data point.

[0016] Optionally, the wake-up device further includes: A temperature acquisition device is used to acquire the temperature data of the valve; The temperature acquisition device is located at the valve and is electrically connected to the device to be woken up.

[0017] Using the above scheme, when battery thermal runaway occurs, the generated high-temperature gas pushes the valve cover, causing the valve stem to move in the first direction to open the valve, while also directly heating the valve body. Therefore, the temperature data of the valve measured by the temperature acquisition device will also show a certain increase. When the valve temperature data exceeds a certain threshold, battery thermal runaway is confirmed, preventing false wake-ups caused by vibration leading to the valve having a first opening degree, further improving the reliability of the device to be woken up (i.e., the BMS).

[0018] Optionally, the valve is further configured to: when the internal air pressure of the energy storage system reaches a first air pressure threshold, the valve is placed at a first valve opening degree under the action of the air pressure.

[0019] Only when thermal runaway occurs, the battery of the energy storage system reacts violently and generates a large amount of high-pressure gas, causing the internal gas pressure of the energy storage system to rise sharply or even exceed the first gas pressure threshold. The valve will reach the first valve opening degree under the action of gas pressure, avoiding false wake-up of the device to be woken up (i.e., BMS) in non-fault scenarios and improving the accuracy of judgment.

[0020] According to a second aspect of this application, a wake-up control method is provided, applied to a wake-up device, the wake-up device including a valve and a power supply wake-up device, the valve being configured to have a first valve opening degree and connected between the wake-up power supply and the power supply wake-up device; the method includes: When the valve is at the first valve opening degree, the power supply wake-up device is in the conducting state to wake up the device to be woken up and execute the preset function.

[0021] Optionally, the power supply wake-up device includes: a first external conductive component electrically connected to one of the wake-up power supply and the device to be woken up; and a second external conductive component electrically connected to the other of the wake-up power supply and the device to be woken up; wherein the valve is connected between the first external conductive component and the second external conductive component; wherein when the valve is in a first valve opening position, the power supply wake-up device is in a conducting state, including: When the valve is at the first valve opening degree, the first external conductive component and the second external conductive component are connected through the valve to enable the power supply wake-up device to be in a conductive state.

[0022] Optionally, the valve is further configured to have a second valve opening degree; the method further includes: When the valve is in the second valve opening position, the power supply wake-up device is in the off state, so that the wake-up power supply is disconnected from the device to be woken up.

[0023] Optionally, when the valve is at the second valve opening degree, the power supply wake-up device is in a disconnected state, so that the wake-up power supply disconnects the power interaction with the device to be woken up, including: When the valve is in the second valve opening position, the first external conductive component is disconnected from the second external conductive component, so that the power supply wake-up device is in the off state.

[0024] According to a third aspect of this application, a computer-readable storage medium is provided, on which a computer program or instructions are stored, wherein the computer program or instructions, when executed by a processor, implement the wake-up control method as described above.

[0025] According to a fourth aspect of this application, an energy storage system is provided, the energy storage system comprising a battery, a wake-up power supply, a device to be woken up, and a wake-up device as described above.

[0026] According to a fourth aspect of this application, a vehicle is provided, the vehicle including a wake-up device as described above, or an energy storage system as described above.

[0027] In summary, the technical solution provided in this application includes a wake-up device comprising a valve and a power supply wake-up device. The valve is configured with a first valve opening, and the power supply wake-up device is configured to have a conductive state that enables electrical interaction between the wake-up power supply and the device to be woken up. When the valve is at the first valve opening, the power supply wake-up device is in a conductive state to wake up the device to execute a preset function. Through the coordinated operation of the valve and the power supply wake-up device, electrical interaction between the wake-up power supply and the device to be woken up is achieved. The mechanical characteristics of the valve enable the conduction of the power supply wake-up device, thereby realizing electrical interaction between the device to be woken up and the wake-up power supply. This eliminates the need for a separate sensor to identify the valve state and transmit sensor signals, effectively reducing the structural complexity of the battery system.

In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0038] Based on the aforementioned background technology, a state identification system for explosion-proof valves is disclosed in related technologies. The identification system includes at least one mechanical explosion-proof valve, a thermal runaway acquisition module, a battery pack, and an explosion-proof valve state identification circuit. The mechanical explosion-proof valve and the thermal runaway acquisition module are mounted on the battery pack. The explosion-proof valve state identification circuit is connected to the continuity monitoring devices in all mechanical explosion-proof valves. By acquiring the circuit output signal output by the explosion-proof valve state identification circuit, which includes a valve opening wake-up signal output when the continuity monitoring device is in a connected state, the system acquires thermal runaway information collected by the thermal runaway acquisition module under the control of the valve opening wake-up signal, and determines the opening state of the mechanical explosion-proof valve based on the thermal runaway information.

[0039] In this identification system, the opening status of the explosion-proof valve is identified to output a valve opening wake-up signal, which is used to wake up the BMS. However, this wake-up method still relies on the transmission of sensor signals, requiring additional status identification circuits and signal processing modules. This results in a complex battery system structure and may reduce reliability, leading to response delays or false alarms in thermal runaway emergencies.

[0040] In view of this, embodiments of this application provide a wake-up device that can improve the accuracy of determining thermal runaway in a battery of an energy storage system.

[0041] According to a first aspect of this application, a wake-up device 200 is provided, which is connected between a wake-up power supply 10 and a device 40 to be woken up. The wake-up device 200 includes a valve 20 and a power supply wake-up device 30. In the embodiments of this application, the valve 20 is configured to have a first valve opening degree, and the power supply wake-up device 30 is configured to have a conducting state that enables the wake-up power supply 10 and the device 40 to be woken up to form an electrical interaction.

[0042] When valve 20 is in the first valve opening position, the power supply wake-up device 30 is in the conducting state to wake up the device 40 to perform the preset function.

[0043] The device to be woken up 40 includes a BMS400. After the BMS400 and the wake-up power supply 10 interact electrically, the BMS400 is woken up, enabling it to perform preset functions to determine whether thermal runaway has occurred. In the event of thermal runaway, it can take measures to prevent the spread of thermal runaway. This reduces the risk of fire and explosion of the energy storage system due to thermal runaway and improves the safety of the entire energy storage system.

[0044] In this embodiment, the energy storage system 1000 can be an energy storage system included in an electrical device. The energy storage system 1000 includes multiple batteries 300, which provide electrical energy to the electrical device. For example, the electrical device can be a vehicle, the energy storage system can be the vehicle's power battery pack, and the wake-up power supply 10 can be the vehicle's 12V low-voltage battery.

[0045] The wake-up power supply 10 refers to an independent, dedicated low-voltage power supply that provides the energy required to start the device 40 (i.e., BMS400) when it is in a dormant state. The function of the wake-up power supply 10 is to supply power to the device 40 (i.e., BMS400), enabling it to wake from its dormant state to normal operation, thereby determining whether the battery 300 of the energy storage system is in a thermal runaway state. The first valve opening degree of valve 20 refers to the degree to which valve 20 can open under air pressure. Opening valve 20 allows high-pressure gas to be discharged from the energy storage system 1000 and also enables the power supply wake-up device 30 to be in a conductive state. The opening degree of valve 20 is coupled with the internal air pressure within the energy storage system 1000.

[0046] The technical solution provided in this application embodiment includes a wake-up device 200 comprising a valve 20 and a power supply wake-up device 30. The valve 20 is configured to have a first valve opening degree, and the power supply wake-up device 30 is configured to have a conducting state that enables the wake-up power supply 10 to form an electrical energy interaction with the device to be woken up 40 (i.e., BMS400). When the valve 20 is in the first valve opening degree, the power supply wake-up device 30 is in the conducting state to wake up the device to be woken up 40 (i.e., BMS400) to perform a preset function.

[0047] By cooperating with the power supply wake-up device 30, the power exchange between the wake-up power supply 10 and the device to be woken up 40 (i.e., BMS400) is realized. The mechanical characteristics of the valve 20 are used to enable the power supply wake-up device 30 to conduct, thereby realizing the power exchange between the device to be woken up 40 and the wake-up power supply 10. There is no need to set up a separate sensor to identify the valve status for the transmission of sensor signals, which effectively reduces the structural complexity of the energy storage system.

[0048] It is understood that in this embodiment of the application, the mechanical action of valve 20 is coordinated with the circuit conduction of power supply wake-up device 30 to wake up the device 40 to be woken up. When the battery 300 included in the energy storage system triggers thermal runaway, the internal air pressure of the energy storage system will increase, causing valve 20 to open and be at the first valve opening degree, thereby enabling power supply wake-up device 30 to be in the conducting state before triggering the wake-up action. This avoids false wake-up in non-fault scenarios, further improves the accuracy of thermal runaway fault identification, avoids invalid warnings caused by misjudgment of a single signal, or the inability to smoothly transmit sensor signals.

[0049] In some embodiments, valve 20 is further configured to have a second valve opening; wherein, when valve 20 is in the second valve opening state, the power supply wake-up device 30 is in a disconnected state, so that the wake-up power supply 10 disconnects from the power interaction with the device to be woken up 40.

[0050] By associating the second valve opening of valve 20 with the disconnected state of power supply wake-up device 30, the power between wake-up power supply 10 and device 40 to be woken up (i.e. BMS400) can be kept in a state of disconnected power exchange, thereby reducing the power consumption of wake-up power supply 10.

[0051] One point to note is that in this embodiment, power supply wake-up is only triggered when the internal pressure of the energy storage system reaches a threshold and valve 20 reaches the first valve opening. On one hand, if the internal pressure of the energy storage system does not reach the pressure threshold, the opening of valve 20 will not reach the first valve opening. However, because there is a certain pressure inside the energy storage system, pressure relief is required, so valve 20 will open to a certain extent. In this case, the opening of valve 20 is less than the first valve opening but greater than the second valve opening, allowing the high-pressure gas inside the energy storage system to be discharged, meeting the pressure balance requirements of the energy storage system. On the other hand, this also prevents the device to be woken up 40 (i.e., BMS400) from being mistakenly woken up, ensuring the normal operation of the device to be woken up 40 (i.e., BMS400).

[0052] In some embodiments, the power-powered wake-up device 30 includes a first external conductive element 301 and a second external conductive element 302. In this embodiment, the first external conductive element 301 is electrically connected to one of the wake-up power supply 10 and the device to be woken up 40; the second external conductive element 302 is electrically connected to the other of the wake-up power supply 10 and the device to be woken up 40.

[0053] The valve 20 is connected between the first external conductive component 301 and the second external conductive component 302. When the valve 20 is in the first valve opening position, the first external conductive component 301 and the second external conductive component 302 are connected through the valve 20 to make the power supply wake-up device 30 in a conductive state. When the valve 20 is in the second valve opening position, the first external conductive component 301 and the second external conductive component 302 are disconnected to make the power supply wake-up device 30 in a disconnected state.

[0054] By adopting the above technical solution, the power supply wake-up device 30 is turned on through the physical connection between the first external conductive component 301, the valve 20 and the second external conductive component 302, without relying on sensor signals.

[0055] It is understandable that when valve 20 is opened to the first valve opening degree, valve 20 can physically connect two external conductive parts 203 to form an electrical energy interaction circuit between the wake-up power supply 10 and the device to be woken up 40 (i.e., BMS400); when it is in the second opening degree, the mechanical physical connection is directly disconnected, so as to achieve the effect of conduction and disconnection from the physical level.

[0056] In some embodiments, the first valve opening includes the maximum opening of valve 20, and the second valve opening includes the minimum opening of valve 20.

[0057] It is understood that the first valve opening degree in this embodiment includes the maximum opening degree of valve 20, which refers to the maximum opening degree that valve 20 can reach after thermal runaway of battery 300 causes a sharp increase in gas pressure inside the energy storage system. At the maximum opening degree, the first external conductive component 301 and the second external conductive component 302 are electrically connected under the action of valve 20, realizing the electrical energy interaction between wake-up power supply 10 and device 40 to be woken up. The second valve opening degree in this embodiment includes the minimum opening degree of valve 20, which refers to the near-complete seal between valve cover 202 and valve seat 201 of valve 20 or a small exhaust gap between them under normal operation of energy storage system (such as use or charging) or slight gas pressure fluctuation (such as normal exhaust caused by ambient temperature change). The first external conductive component 301 and the second external conductive component 302 are disconnected from the electrical connection, so that the electrical energy interaction between wake-up power supply 10 and device 40 to be woken up is disconnected.

[0058] Exemplarily, the valve 20 in this embodiment includes a valve seat 201, a valve cover 202, a conductive element 203, a valve stem 204, an insulating connector 205, a reset element 210, and a conductive actuating element 215. The reset element 210 is sleeved on the valve stem 204, with one end abutting against the valve seat 201 and the other end abutting against the valve stem 204. The conductive element 203 is insulated from the valve stem 204 via the insulating connector 205, and the insulating connector 205, the valve cover 202, and the valve stem 204 form an integral unit. The conductive element 203 is movably connected to the valve stem 204. The conductive actuating element 215 applies a biasing force to the conductive element 203, enabling it to move in a second direction, thus giving the conductive actuating element 215 a tendency to move in the second direction to the conducting position 201a. The valve stem 204 passes through the through-space of the valve seat 201 and connects to the valve cover 202. The direction of movement of the conductive element 203 intersects the direction of movement of the valve stem 204.

[0059] When valve 20 is in the first valve opening position, after valve cover 202, valve stem 204, and insulating connector 205 move a certain distance along the first direction, conductive element 203 can move along the second direction to the conducting position 201a under the bias pressure provided by conductive element 215. In the conducting position 201a, conductive element 203 can be connected to the first external conductive element 301 and the second external conductive element 302 respectively. In this way, a current flow path is formed between the first external conductive element 301, conductive element 203, and second external conductive element 302. The first external conductive element 301 and the second external conductive element 302 are respectively connected to the wake-up power supply 10 and the device to be woken up 40. When the first external conductive element 301 and the second external conductive element 302 are electrically connected by conductive element 203, the power exchange between the wake-up power supply 10 and the device to be woken up 40 is realized, thereby waking up the device to be woken up 40 (i.e., BMS400).

[0060] It should be noted that in this embodiment, the second valve opening is at its minimum, thus forming a sealed connection between the valve cover 202 and the valve seat 201. This ensures the airtightness of the battery pack, preventing external substances (such as moisture and dust) from entering the energy storage system and avoiding corrosion or short-circuit risks to components such as batteries and wiring harnesses. When the valve 10 is at its first valve opening, the reset member 210 is compressed, allowing the valve stem 204 and the insulating connector 215 to tend to move away from the valve seat 201 along the first direction.

[0061] In some embodiments, the preset functions include at least one of the following: collecting temperature data of valve 20; collecting temperature data of battery 300; collecting voltage data of battery 300; and collecting pressure data inside battery 300.

[0062] In this embodiment, after the device to be woken up 40 (i.e., BMS400) is woken up, it performs the acquisition of temperature data of valve 20, voltage data of battery 300, and pressure data inside battery 300. Based on these data, it determines whether battery 300 has experienced thermal runaway. This method improves the accuracy of determining whether battery 300 has experienced thermal runaway by not relying on a single data point.

[0063] In this embodiment, the data acquisition of the device to be woken up 40 (i.e., BMS400) can be achieved by the temperature acquisition sensor, voltage sensor and pressure sensor included in the device to be woken up 40 (i.e. BMS400) to collect the temperature data of the battery 300 and the voltage data of the valve 20, so as to avoid monitoring failure due to the failure of a single sensor.

[0064] In some embodiments, the wake-up device 200 further includes a temperature acquisition device. The temperature acquisition device in this embodiment is used to acquire temperature data of the valve 20; wherein the temperature acquisition device is disposed on the valve 20 and electrically connected to the device to be woken up 40.

[0065] Using the above scheme, when thermal runaway of battery 300 occurs, the generated high-temperature gas pushes the valve cover 202 of valve 20, causing the valve stem 204 to move in the first direction, thus opening valve 20, and also directly heats the valve body. Therefore, the temperature data of valve 20 measured by the temperature acquisition device will also increase to a certain extent. When the temperature data of valve 20 exceeds a certain threshold, it is confirmed that thermal runaway of battery 300 has occurred, avoiding false wake-up of device 40 (i.e., BMS400) due to mechanical vibration causing valve 20 to have a first valve opening degree, thereby further improving the reliability of wake-up of device 40 (i.e., BMS400).

[0066] For example, in this embodiment of the application, there can be multiple valves 20, with one or more valves 20 provided for each battery 300. Since the temperature of a battery 300 that has experienced thermal runaway will increase rapidly, the temperature of the valves 20 provided for each battery 300 will change drastically (for example, the temperature will rise rapidly to above 80°C within ten seconds). By collecting the temperature data of each valve 20, the location of the battery 300 that has experienced thermal runaway can be identified, and targeted fault operations can be performed (such as alarm prompts, limiting the charging and discharging of the battery 300, cutting off the high-voltage circuit, and activating the fire extinguishing device).

[0067] It is understood that the temperature acquisition device in this embodiment may include a temperature acquisition element 303, which is disposed on the valve 20 and electrically connected to the device to be woken up 40 (BMS400). The temperature acquisition element 303 is capable of acquiring the temperature of the valve 20 and sending the acquired temperature to the device to be woken up 40 (BMS400). Exemplarily, the temperature acquisition element 303 may be a temperature sensor disposed on the second fixing member 207.

[0068] In some embodiments, valve 20 is further configured to: when the internal air pressure of the energy storage system 1000 reaches a first air pressure threshold, valve 20 is placed at a first valve opening degree under the action of air pressure.

[0069] When the battery 300 of the energy storage system is operating normally (such as during charging or driving), the internal air pressure will only fluctuate slightly due to changes in ambient temperature and slight gas production, which is far below the first air pressure threshold. The valve 20 always maintains the second opening (minimum valve 20 opening). The first external conductive component 301 and the second external conductive component 302 of the power supply wake-up device 30 remain disconnected, thus preventing accidental wake-up of the device to be woken up 40 (i.e., BMS400). Only when thermal runaway occurs will the battery 300 of the energy storage system react violently and generate a large amount of high-pressure gas, causing the air pressure inside the energy storage system to rise sharply or even exceed the first air pressure threshold. The valve 20 will reach the first valve opening under the action of air pressure, avoiding accidental wake-up of the device to be woken up 40 (i.e., BMS400) in non-fault scenarios and improving the accuracy of judgment.

[0070] It is understood that the valve 20 opening degree in the embodiments of this application is coupled with the gas pressure inside the energy storage system 1000.

[0071] In summary, the wake-up device 200 in this embodiment, through the mechanical connection between the valve 20 and the power supply wake-up device 30, does not rely on the transmission of sensor signals, thus avoiding signal transmission failure due to sensor malfunction. Even in extreme scenarios such as vehicle power failure or BMS400 hibernation, as long as thermal runaway causes the air pressure to reach the threshold, the valve 20 can still reliably open to the first valve opening degree under the action of air pressure, ensuring uninterrupted pressure relief and wake-up.

[0072] The following is an example to illustrate the valve 20 of the wake-up device 200 in an embodiment of this application.

[0073] like Figure 3 As shown, Figure 3 This is a schematic diagram of the overall structure of the valve 20 provided in an exemplary embodiment of this application.

[0074] See Figure 4 and Figure 5The valve 20 includes a valve seat 201, a valve cover 202, and a conductive element 203. The valve cover 202 is located on one side of the valve seat 201 along a first direction and is configured to move along the first direction under air pressure to give the valve 20 a first valve opening. The conductive element 203 is movably connected to the valve cover 202 and insulated from it, and is configured to move along a second direction to a conducting position 201a. When the valve 20 is at the first valve opening, the conductive element 203 can be in the conducting position 201a relative to the valve seat 201 to enable the wake-up power supply 10 to interact with the battery management system 300. The first direction and the second direction are intersecting.

[0075] Through the above technical solution, when valve 20 is in the first valve opening position, conductive element 203 can be in the conducting position 201a relative to valve seat 201 in the second direction, so that the wake-up power supply 10 and the device to be woken up 40 can form an electrical energy interaction, thereby achieving the effect of waking up the device to be woken up 40. That is, the conductive element 203 between the device to be woken up 40 and the wake-up power supply 10 can be reused on valve 20. While using the adjustment function of valve 20, the mechanical characteristics of valve 20 can also be used to realize the electrical energy interaction between the device to be woken up 40 and the wake-up power supply 10. There is no need to set up a separate sensor to identify the state of valve 20, and there is no need to transmit sensor signals to wake up the device to be woken up 40, which reduces the structural complexity of the energy storage system. The moving direction of valve cover 202 and the moving direction of conductive element 203 intersect, which makes the structure of valve 20 more compact and reduces the space occupied by valve 20, which is beneficial to the arrangement of battery 300.

[0076] It is understood that in this example, the conductive element 203 and the valve cover 202 are movably connected and insulated, meaning that the conductive element 203 and the valve cover 202 are movably assembled. The movement of the conductive element 203 along the second direction and the movement of the valve cover 202 along the first direction are independent movements, yet they are coupled. It should be noted that, for ease of description, please refer to... Figure 4 In this embodiment, the first direction refers to the X direction, and the second direction refers to the Y direction, which are perpendicular to each other. The conductive component 203 moves along the second direction Y, including moving along the Y1 and Y2 directions, and the valve cover 202 moves along the first direction X, including moving along the X1 and X2 directions. The specific direction of movement is determined by the gas pressure within the energy storage system.

[0077] It is understandable that valve 20 in this example can serve to relieve pressure, that is, to balance the pressure inside and outside the energy storage system 1000. The specific details of pressure relief will be described later and will not be repeated here.

[0078] In this example, see Figure 4 , Figure 6 , Figure 7 and Figure 8 The valve 20 further includes an insulating connector 205. In this embodiment, the insulating connector 205 is used to insulate the valve cover 202 and the conductive element 203; wherein, the insulating connector 205 and the valve cover 202 form an integral whole, and under the action of the force provided by the valve cover 202, it moves synchronously with the valve cover 202 along the first direction X.

[0079] By providing the insulating connector 205, the valve cover 202 and the conductive element 203 are insulated from each other, and the insulating connector 205 and the valve cover 202 form an integral unit. Under the force provided by the valve cover 202, the connector 205 moves synchronously with the valve cover 202 along the first direction X. On the one hand, under the action of the insulating connector 205, no electrical conduction path is formed between the conductive element 203 and the valve cover 202, ensuring that the conductive element 203 serves as a reliable conductive path between the wake-up power supply 10 and the device to be woken up 40 (i.e., BMS400). On the other hand, under the action of the force provided by the valve cover 202, the insulating connector 205 can move synchronously with the valve cover 202 along the first direction X, eliminating the need for an additional structure to drive the insulating connector 205 to move along the first direction X. This further improves the compactness of the valve 20 and reduces the volume occupied by the valve 20.

[0080] Taking the insulating connector 205 as an example, which can be constructed as a sheet-like structure with a rectangular shape, and the conductive element 203 as a block-like structure, this design increases the contact area between the insulating connector 205 and the conductive element 203, preventing accidental activation and potential power exchange between the wake-up power supply 10 and the BMS400, thus avoiding increased power consumption due to accidental wake-up of the BMS400. The insulating connector 205 can be made of an insulating material. In the second direction Y, the insulating connector 205 is located at one end of the conductive element 203.

[0081] In this example, see Figure 4 The insulating connector 205 is configured such that when the valve 20 is in the first valve opening position, the insulating connector 205 is in the released position 201e; wherein, when the insulating connector 205 is in the released position 201e, the conductive element 203 is in the conducting position 201a. This technical solution, on the one hand, requires the insulating connector 205 to move first to release the restriction on the conductive element 203, and then to bring the conductive element 203 into the conducting position 201a, ensuring reliable electrical energy exchange between the wake-up power supply 10 and the BMS400, avoiding wake-up failure of the BMS400 due to jamming or insufficient travel; on the other hand, it also avoids false wake-up caused by vibration of the insulating connector 205.

[0082] Understandably, see Figure 5In the first direction X, the insulating connector 205 abuts against the valve stem 204. Thus, when the valve stem 204 moves in the first direction, the insulating connector 205 can also move in the first direction, thereby enabling the insulating connector 205 to switch between the release position 201e and the isolation position 201c.

[0083] In this example, see Figure 9 The insulating connector 205 is further configured to be in an isolated position 201c relative to the valve seat 201. The conductive element 203 in this embodiment is further configured to be in a disconnected position 201d relative to the valve seat 201. When the insulating connector 205 is in the isolated position 201c, the conductive element 203 forms surface contact with the insulating connector 205, and the conductive element 203 is in the disconnected position 201d, so that the wake-up power supply 10 disconnects its power interaction with the battery 300 management system. By adopting this scheme, the conductive element 203 and the insulating connector 205 form surface contact, which increases the contact area between them. Thus, when the insulating connector 205 is in the isolated position 201c, the conductive element 203 can be in the disconnected position 201d. When the insulating connector 205 moves from the isolation position 201c to the release position 201e along the first direction, the insulating connector 205 and the conductive member 203 are in contact at the disconnected surface, thus releasing the restriction on the conductive member 203 and allowing the conductive member 203 to move from the disconnected position 201d to the conducting position 201a along the second direction Y.

[0084] Understandably, when the insulating connector 205 is in the isolated position 201c relative to the valve seat 201 and the conductive element 203 is in the disconnected position 201d, the valve 20 is in the second valve opening degree, making the valve 20 closed, and the conductive element 203 is in the disconnected position 201d. Thus, the power supply 10 and the BMS 400 are disconnected. When the valve 20 has a first valve opening degree, it is in the open state, and the conductive element 203 is in the conducting position 101a. Thus, the power supply 10 and the device to be woken up 40 exchange electrical energy to wake up the BMS 400.

[0085] It should be noted that in this embodiment, the opening degree of the first valve is greater than that of the second valve. Furthermore, during the process of switching valve 20 from the second valve opening degree to the first valve opening degree, valve 20 is in a gradually opening state, meaning the opening degree of valve 20 gradually increases. During this process, no electrical interaction occurs between the wake-up power supply 10 and the BMS400, meaning the BMS400 is not woken up.

[0086] In this example, see Figure 9When the insulating connector 205 is in the isolated position 201c and the conductive member 203 is in the disconnected position 201d, the projections of the insulating connector 205 and the conductive member 203 overlap on a projection plane perpendicular to the second direction Y. This ensures stable surface contact between the insulating connector 205 and the conductive member 203.

[0087] In this example, see Figure 4 and Figure 9 The valve 20 further includes a valve stem 204 and a reset member 210. The valve stem 204 is located between the valve cover 202 and the insulating connector 205; the reset member 210 is movably connected between the valve seat 201 and the valve stem 204, and the reset member 210 is sleeved on the valve stem 204; wherein, the reset member 210 is configured to apply a force to the valve stem 204 so that the valve stem 204 tends to move away from the valve seat 201 in a first direction.

[0088] In this technical solution, the reset member 210 is sleeved on the valve stem 204 and applies a force to the valve stem 204, causing the valve stem 204 to tend to move away from the valve seat 201 along the first direction X1. This allows the valve stem 204 to move towards the valve seat 201 as the pressure within the energy storage system 1000 gradually decreases, using the force provided by the reset member 210 to move the valve cover 202 closer to the valve seat 201, thus resetting the valve cover 202. It also allows the conductive member 203 to move from the conducting position 201a to the disconnected position 201d along the second direction, thereby resetting the valve 20. Furthermore, the reset member 210 maintains the relative positional stability of the valve cover 202 and the valve seat 201, reducing the risk of leakage due to separation between the valve cover 202 and the valve 20 when the pressure inside the energy storage system 1000 has not reached a certain value, thus improving sealing performance.

[0089] As a more specific technical solution, refer to Figure 9In this embodiment, one end of the reset member 210 abuts against the valve seat 201, and the other end abuts against the valve stem 204. The valve seat 201 has a first through space 201b extending along the first direction X. Parts of the valve cover 202 and the valve stem 204 are located on both sides of the valve seat 201. The other part of the valve stem 204 can pass through the first through space 201b and connect to the valve cover 202. Since the valve seat 201 is fixedly mounted on the energy storage system 1000, for example, fixedly mounted on the housing of the energy storage system 1000, the reset member 210 is in a compressed state when the valve 20 is at the first valve opening degree and has a tendency to restore its shape. If the air pressure on the valve cover 202 gradually decreases, the reset member 210 can overcome the air pressure on the valve cover 202 to restore its shape, thereby driving the valve stem 204 to move away from the valve seat 201 along the first direction, while the valve cover 202 continuously moves closer to the valve seat 201, and finally realizes the reset of the valve cover 202, and the valve 20 is in the second valve opening degree.

[0090] Understandably, the second valve opening of valve 20 keeps valve 20 in a closed state, and the conductive element 203 is in the disconnected position 201d, thus disconnecting the electrical interaction between the wake-up power supply 10 and the device to be woken up 40. The first valve opening of valve 20 keeps valve 20 in an open state, and the conductive element 203 is in the conductive position 101a, thus establishing electrical interaction between the wake-up power supply 10 and the device to be woken up 40 to wake up BMS400.

[0091] For example, refer to Figures 14 to 17 The reset member 210 can be constructed as a columnar spring. The valve seat 201 includes an outer ring body 2011 and an inner ring body 2012 that are spaced apart and concentrically arranged, and three arms 2013 located between the outer ring body 2011 and the inner ring body 2012. The inner ring body 2012 defines a first through space 201b. One end of the columnar spring abuts against the inner ring body 2012. The end of the valve stem 204 passes through the first through space 201b and is connected to the valve cover 202.

[0092] In this example, see Figure 9 and Figure 10 The valve 20 further includes a conductive element 215. In this embodiment, the conductive element 215 is connected to the conductive element 203. The conductive element 215 is configured to provide a force to the conductive element 203 in the second direction Y, so that the conductive element 203 tends to move from the disconnected position 201d to the connected position 201a along the second direction Y1.

[0093] By setting the conductive element 215, on the one hand, it provides a driving force for the movement of the conductive element 203 along the second direction Y. When the insulating connector 205 moves from the isolation position 201c to the release position 201e along the first direction X2, the insulating connector 205 releases the restriction on the movement of the conductive element 203 along the second direction Y1. Thus, the conductive element 215 drives the conductive element 203 to move along the second direction Y1 from the disconnect position 201d to the conduction position 201a, thereby achieving the effect of electrical energy interaction between the wake-up power supply 10 and the BMS400. On the other hand, the force provided by the conductive element 215 ensures that the conductive element 203 can remain in the conduction position 201a after reaching the conduction position 201a. Furthermore, the way the conductive element 215 drives the conductive element 203 to move along the second direction Y1 does not depend on any external power supply or electronic control signal. As long as the mechanical constraint is released, the driving action will occur, reducing the use of sensor elements.

[0094] For example, the conductive element 215 in the embodiments of this application can be constructed as a conductive spring, and more specifically, it can be constructed as a metal columnar spring.

[0095] Since the valve cover 202, valve stem 204, and insulating connector 205 form a single unit, the insulating connector 205 will also return to the isolation position 201c. As a further technical solution, in the embodiments of this application, see... Figure 4 The insulating connector 205 is provided with a first guide slope 2051 at one end near the conductive member 203, and the conductive member 203 is provided with a second guide slope 2031. When the conductive member 203 is in the conducting position 201a, as the pressure in the energy storage system 1000 gradually decreases, under the action of the reset member 210, the first guide slope 2051 can act and be inserted into the second guide slope 2031 of the conductive member 203. This can overcome the force exerted on the conductive member 203 by the conductive member 215, and the conductive member 203 can move from the conducting position 101a to the disconnected position 201d along the second direction Y2, while the insulating connector 205 also moves from the released position 201e to the isolated position 201c.

[0096] In this example, see Figures 9 to 13 The valve 20 includes a first fixing member 206 and a second fixing member 207. In this embodiment, the first fixing member 206 is fixedly disposed relative to the valve seat 201 and provides a first receiving space 206a. The second fixing member 207 is fixedly disposed relative to the first fixing member 206 and provides a second receiving space 207a communicating with the first receiving space 206a.

[0097] The valve stem 204 is located in the first accommodating space 206a, the conductive element 203 is located in the second accommodating space 207a, the conductive actuating element 215 is movably connected between the second fixing element 207 and the conductive element 203, and a portion of the insulating connecting element 205 is located in the first accommodating space 206a and a portion of the insulating connecting element 205 is located in the second accommodating space 207a.

[0098] In this embodiment, the first receiving space 206a of the first fixing member 206 can partially accommodate the valve stem 204 and the insulating connector 205, while the second receiving space 207a of the second fixing member 207 can accommodate the conductive member 203 and the remaining part of the insulating connector 205. The spatial structure arrangement of the first fixing member 206 and the second fixing member 207 is reasonable and facilitates assembly and disassembly.

[0099] See Figure 9 , Figure 11 In this embodiment of the application, the first fixing member 206 and the second fixing member 207 are both constructed as rotating bodies that rotate around the center line 20b. The rotating bodies have a first accommodating space 206a and a second accommodating space 207a. The first accommodating space 206a of the first fixing member 206 is open at both ends, and the second accommodating space 207a of the second fixing member 207 is open at one end. In this way, the first accommodating space 206a and the second accommodating space 207a can be connected.

[0100] It should be noted that the first fixing member 206 and the second fixing member 207 in the embodiments of this application are both made of insulating material.

[0101] In this example, see Figure 4 The power-powered wake-up device 30 includes a first external conductive element 301 connected to one of the wake-up power supply 10 and the battery 300 management system; a second external conductive element 302 is configured to connect to the other of the wake-up power supply 10 and the battery 300 management system. (See also...) Figure 4 In this embodiment, the conductive element 203 is located between the first external conductive element 301 and the second external conductive element 302. When the insulating connector 205 is in the isolated position 201c, a portion of the insulating connector 205 is located between the conductive element 203 and the second external conductive element 302; when the insulating connector 205 is in the released position 201e, the conductive actuating element 215 and the conductive element 203 are respectively connected to the first external conductive element 301 and the second external conductive element 302.

[0102] By adopting this technical solution, the wake-up power supply 10 and BMS400 are connected respectively through the first external conductive component 301 and the second external conductive component 302. In this way, when the valve 20 is in the first valve opening position, the conductive component 203 is in the conducting position 201a so as to connect the first external conductive component 301 and the second external conductive component 302. Thus, a complete conductive path is formed, avoiding the interruption of power transmission between the wake-up power supply 10 and the device to be woken up 40 (i.e., BMS400) due to poor contact or unstable connection, thereby improving the reliability of the electrical connection.

[0103] Understandably, see Figure 4 When the insulating connector 205 is in the released position 201e, it releases its electrical isolation function from the conductive element 203 and the second external conductive element 302. In this case, the conductive element 215 and the conductive element 203 are respectively connected to the first external conductive element 301 and the second external conductive element 302, thus establishing the current path between the conductive elements 215 and 203 and the first and second external conductive elements 301 and 302. (See reference...) Figure 9 When the insulating connector 205 is in the isolated position 201c, a portion of the insulating connector 205 is located between the conductive element 203 and the second external conductive element 302. In this case, the insulating connector 205 serves to electrically isolate the conductive element 203 and the second external conductive element 302. For example, the first external conductive element 301 is connected to the wake-up power supply 10, and the second external conductive element 302 is connected to the device to be woken up 40.

[0104] In this example, see Figure 9 The conductive member 203 is provided with a third receiving space 203a along the second direction to accommodate the conductive member 215. Part of the conductive member 215 is connected to the first external conductive member 301, and part is connected to the conductive member 203. When the conductive member 203 moves along the second direction to the conducting position 201a, part of the conductive member 215 is located outside the third receiving space 203a, and the end of the conductive member 203 away from the insulating connector 205 is separated from the first external conductive member 301, while the end of the conductive member 203 near the insulating connector 205 forms a surface contact with the second external conductive member 302.

[0105] Through the above technical solution, on the one hand, at least a portion of the conductive element 215 is located within the third accommodating space 203a of the conductive element 203, and part of the conductive element 215 is connected to the first external conductive element 301, and part is connected to the conductive element 203, forming a module with the conductive element 215 and the conductive element 203 as a whole, which can save the space occupied by the valve 20 in the second direction and improve the compactness of the valve 20; on the other hand, when the conductive element 203 moves to the conducting position 201a along the second direction, the conductive element... Part of component 215 is located outside the third receiving space 203a, and the end of conductive component 203 away from insulating connector 205 is separated from the first external conductive component 301, which realizes the effect of conductive component 203 moving from disconnected position 201d to conductive position 201a, making the movement more stable; on the other hand, the end of conductive component 203 near insulating connector 205 forms a surface contact with the second external conductive component 302, which can increase the contact area between conductive component 203 and the second external conductive component 302, and avoid wake-up failure due to poor contact.

[0106] It should be noted that when the insulating connector 205 is in the isolation position 201c in this embodiment, the conductive member 215 is compressed and stores a certain amount of elastic potential energy; when the insulating connector 205 is removed from between the conductive member 203 and the second external connector to move to the release position 201e, the end of the conductive member 203 away from the insulating connector 205 is separated from the first external conductive member 301, and the end of the conductive member 203 near the insulating connector 205 forms a surface contact with the second external conductive member 302, which improves the stability of current transmission.

[0107] See below Figure 9 The specific configuration and structure of the first external conductive component 301 and the second external conductive component 302 of the power supply wake-up device 30 are described.

[0108] In this example, valve 20 has a centerline 20b, and a first external conductive element 301 and a second external conductive element 302 are symmetrically arranged about the centerline 20b on the second fixing element 207. This ensures that the connection between the first external conductive element 301 and the second external conductive element 302 and the conductive element 203 and the conductive action element 215 is consistent, for example, the contact area and contact points are the same, maintaining consistent conductivity.

[0109] In this example, see Figure 9 At least one of the first external conductive member 301 and the second external conductive member 302 includes: a first sub-external conductive member 3001 located in the second receiving space 207a; and a second sub-external conductive member 3002 connected to the first sub-external conductive member 3001.

[0110] Among them, reference Figure 9 and Figure 11 The second fixing member 207 has a guide channel 207c that runs through the first direction. A portion of the second external conductive member 3002 passes through the guide channel 207c and is connected to the wake-up power supply 10 or the device to be woken up 40 (i.e., BMS400).

[0111] By adopting this technical solution, the corresponding external conductive components are segmented to enable reasonable arrangement of the external conductive components within a limited space, avoiding interference with other structures, such as valve cover 202 and conductive component 203.

[0112] The first external conductive component 3001 serves as a conductive connection, while the second external conductive component 3002 serves as a connector to the outside (including the wake-up power supply 10 and the device to be woken up 40 (i.e., BMS400)).

[0113] For example, the first external conductive component 3001 and the second external conductive component 3002 are separately configured. See also Figure 9 In the embodiments of this application, the first sub-external conductive element 3001 included in the first external conductive element 301 and the second external conductive element 302 is constructed as a sheet structure with a rectangular shape. The second sub-external conductive element 3002 can be a wire, one end of which is in contact with the sheet structure of the first sub-external conductive element 203.

[0114] In order to form a stable connection between the first sub-external conductive element 3001 and the second sub-external conductive element 3002, in this example, the projection of the first sub-external conductive element 3001 on the projection plane perpendicular to the second direction overlaps with the projection of the second sub-external conductive element 3002 on the projection plane.

[0115] Thus, along the second direction Y, the first sub-external conductive component 3001 is located on one side of the second sub-external conductive component 3002, and the two are in contact, which can ensure that a stable connection is formed between them.

[0116] Regarding the contact between the first external conductive component 3001 and the second external conductive component 3002, it can be understood that the first external conductive component 3001 is attached between the second external conductive component 3002. This increases the contact area between the first external conductive component 3001 and the second external conductive component 3002, enabling a more stable electrical energy interaction between the wake-up power supply 10 and the BMS400.

[0117] To better establish a stable connection between the first external conductive component 3001 and the second fixing component 207, in this example, see... Figures 11 to 13A insertion groove 207b can be formed on the body of the second fixing member 207 along the first direction, corresponding to the first sub-external conductive member 3001. The insertion groove 207b is connected to the second receiving space 207a, and a portion of the first sub-external conductive member 3001 is located within the insertion groove 207b. The width of the insertion groove 207b is equal to or slightly greater than the thickness of the first sub-external conductive member 3001. The length of the insertion groove 207b is equal to or slightly greater than the width of the first sub-external conductive member 3001. The depth of the insertion groove 207b is equal to or slightly greater than the length of the first sub-external conductive member 3001. In this way, the first sub-external conductive member 3001 can be stably positioned within the insertion groove 207b.

[0118] It should be noted that the limitations on the width, length and depth of the insertion slot 207b refer to the conformal fit between the insertion slot 207b and the first external conductive component 3001, so that the two can achieve a stable connection.

[0119] Reference Figures 11 to 13 The wall of the second receiving space 207a that defines the second fastener 207 is an irregular wall structure. The irregular wall includes two opposing first walls and two opposing second walls. Along the second direction Y, the first walls are located on one side of the second walls and are arranged adjacent to each other. The first walls and the second walls are arranged in a stepped manner. The two first walls can define the first sub-receiving space, and the two second walls can define the second sub-receiving space.

[0120] When the insulating connector 205 is in the isolated position 201c, part of the insulating connector 205 is located in the second sub-accommodating space, and the conductive member 203 is located in the first sub-accommodating space; when the insulating connector 205 moves to the release position 201e in the X2 direction along the first direction, the insulating connector 205 exits from the second sub-accommodating space, making room for the conductive member 203, so that part of the conductive member 203 is located in the first sub-accommodating space and part of it is located in the second sub-accommodating space, and forms a surface contact with the first sub-external conductive member 3001 in the insertion slot 207b.

[0121] In order to better establish a stable connection between the second external conductive component 3002 and the second fixing component 207, the end of the first external conductive component 3001 is in contact with the bottom of the insertion groove 207b, which can limit the displacement of the first external conductive component 3001 along the X1 direction of the first direction.

[0122] Regarding the guide channel 207c extending along the first direction X of the second fastener 207, see [reference needed]. Figure 12A through groove can be opened on part of the second fixing member 207 along the first direction. The inner wall of the through groove defines a guide channel 207c, and this through groove is connected to the insertion groove 207b. On the projection plane perpendicular to the second direction Y, the orthographic projection of the wall of the through groove and the orthographic projection of the wall of the insertion groove 207b are overlapped. In this way, it can be ensured that the projection of the first sub-external conductive member 3001 on the projection plane overlaps with the projection of the second sub-external conductive member 3002 on the projection plane.

[0123] In this example, see Figure 4 The valve 20 also includes a protective cover 211. In this embodiment, the protective cover 211 is fitted onto the reset member 210; wherein, the first fixing member 206 is connected to the valve seat 201 through the protective cover 211.

[0124] By setting up a protective cover 211, solid particles can be ejected after the battery experiences thermal runaway. The protective cover 211 isolates the solid particles from entering the gap of the reset member 210, preventing them from hindering the compression of the reset member 210, which in turn prevents the conductive member 203 from moving smoothly to the conducting position 101a.

[0125] See Figure 4 As a more specific technical solution, part of the protective cover 211 is located within the first receiving space 206a, and part is located outside the first receiving space 206a. Both ends of the protective cover 211 abut against the valve seat 201 and the first fixing member 206, respectively. This restricts the displacement of the protective cover 211 relative to the valve seat 201 or the first fixing member 206 along the first direction. For example, one end of the protective cover 211 abuts against the inner ring body 2012, and the other end abuts against the first fixing member 206.

[0126] It should be noted that in this embodiment of the application, along the first direction X, a through groove 20c is correspondingly opened on the protective cover 211 and the first fixing member 206. Part of the insulating connector 205 passes through the through groove 20c and abuts against the valve stem 204. It can be understood that the cross-sectional shape of the through groove 20c conformally matches the cross-sectional shape of the insulating connector 205.

[0127] In this example, when valve 20 is in the first valve opening position, a first exhaust passage 20a communicating with the outside is formed between valve seat 201 and valve cover 202.

[0128] After thermal runaway of the battery, the internal pressure of the energy storage system 1000 increases, the reset member 210 is further compressed, and the high-pressure gas pushes the valve cover 202 to move away from the valve seat 201 in the first direction. The high-pressure gas inside the energy storage system 1000 is discharged from the first exhaust channel 20a between the valve cover 202 and the valve seat 201. In this way, the gas pressure inside and outside the energy storage system 1000 can be balanced.

[0129] To improve the sealing performance between valve seat 201 and valve cover 202, in this example, see... Figure 14 and Figure 15 Valve 20 also includes a sealing ring 214 connected between valve seat 201 and valve cover 202. For a more specific technical solution, see [reference needed]. Figure 17 A sealing groove 2011a can be formed on the outer ring body 2011 of the valve seat 201 around the circumference of the valve seat 201. Part of the sealing ring 214 is located in the sealing groove 2011a, and part of it protrudes from the sealing groove 2011a along the first direction X. In this way, when the valve 20 is in the second valve opening position, the side of the valve cover 202 facing the valve seat 201 can abut against the sealing ring 214 to achieve a sealed connection between the valve cover 202 and the valve seat 201.

[0130] For example, in the embodiments of this application, the inner peripheral wall of the outer ring body 2011 of the valve seat 201 is provided with a first inner peripheral wall surface 201f and a second inner peripheral wall surface 201g. The inner diameter of the first inner peripheral wall surface 201f is larger than the inner diameter of the second inner peripheral wall surface 201g, so that a stepped structure can be formed. Then the shape formed by the path of the first exhaust channel 20a described above is an L-shaped exhaust.

[0131] See Figure 4 When valve 20 is in the first valve opening position, the first exhaust channel 20a is connected to the outside of the energy storage system 1000.

[0132] In this example, see Figure 10 The valve stem 204 is provided with a second exhaust channel 204a that communicates with the outside, and the valve cover 202 is also provided with a third exhaust channel 202b that communicates with the second exhaust channel 204a. The protective cover 211 is provided with at least one first through hole 211a, and the valve stem 204 is provided with at least one second through hole 204b that communicates with the first through hole 211a. The first through hole 211a and the second through hole 204b are sequentially connected to the second exhaust channel 204a and the third exhaust channel 202b.

[0133] With this technical solution, the first through hole 211a, the second through hole 204b, the second exhaust channel 204a, and the third exhaust channel 202b are sequentially connected to form a complete exhaust path. The first through hole 211a guides the high-pressure gas in the energy storage system 1000 into the protective space 211b of the protective cover 211, and then into the second exhaust channel 204a along the second through hole 204b. The gas then enters the third exhaust channel 202b of the valve cover 202 along the second exhaust channel 204a, and is discharged from the energy storage system 1000 through the third exhaust channel 202b.

[0134] It should be noted that the valve cover 202 in this embodiment is a valve cover assembly, see reference. Figure 14 , Figure 15 , Figure 16 and Figure 17 It includes a valve cover body 2021 and a valve cover cover 2022. The valve cover body 2021 has a second through space 2021a and a valve cover body space 202c that extend along a first direction X. The second through space 2021a communicates with the valve cover body space 202c. The valve cover cover 2022 is located on the side of the valve cover body 2021 away from the valve stem 204 and covers the valve cover body 2021. A portion of the valve stem 204 passes through the first through space 201b and the second through space 2021a so that the third exhaust channel 202b of the valve cover 202 can communicate with the valve cover body space 202c.

[0135] For example, the valve cover 2022 has multiple first sub-exhaust channels 2022a, and the valve cover body 2021 has multiple second sub-exhaust channels 2021b. When the valve cover 2022 covers the valve cover body 2021, the first sub-exhaust channels 2022a and the second sub-exhaust channels 2021b are arranged in a one-to-one correspondence to form a third exhaust channel 202b. In this way, the gas pressure inside the energy storage system 1000 can be balanced.

[0136] See Figure 4 When valve 20 is in the first valve opening position, the third exhaust channel 202b is connected to the outside of the energy storage system 1000.

[0137] refer to Figure 18 When valve 20 is in the second valve opening position, a fourth venting channel 20d, communicating with the outside, is formed between valve seat 201 and valve cover 202. The third venting channel 202b can communicate with the outside of the energy storage system 1000 through the fourth venting channel 20d.

[0138] The fourth exhaust passage 20d will be explained in detail below.

[0139] During normal operation of the energy storage system 1000, a small amount of high-pressure gas will be generated within the system. Therefore, in order to ensure that valve 20 is in the second valve opening position, some of the gas inside the energy storage system 1000 can be discharged to the external environment to balance the gas inside and outside the system. In this embodiment, reference is made to... Figure 16 and Figure 17In this embodiment, the inner circumferential wall of the outer ring body 2011 of the valve seat 201 is provided with a first inner circumferential wall surface 201f and a second inner circumferential wall surface 201g. The inner diameter of the first inner circumferential wall surface 201f is larger than the inner diameter of the second inner circumferential wall surface 201g. The maximum outer diameter of the valve cover 2022 is slightly smaller than the inner diameter of the first inner circumferential wall surface 201f, and the maximum outer diameter of the valve cover body 2021 is also slightly smaller than the inner diameter of the second inner circumferential wall surface 201g. Thus, referring to... Figure 18 The valve cover body 2021 and valve cover body 2022 of the valve cover 202 form a fourth exhaust channel 20d with a stepped structure (L-shaped) arranged around the center line 20b, and the fourth exhaust channel 20d is connected to the outside, while the fourth exhaust channel 20d is connected to the third exhaust channel 202b.

[0140] Therefore, refer to Figure 18 When valve 20 is in the second valve opening position, a self-exhaust channel is formed: inside the energy storage system 1000 → first through hole 211a of the protective cover 211 → protective space 211b → second through hole 204b → second exhaust channel 204a → valve cover body space 202c → third exhaust channel 202b (first sub-exhaust channel 2022a → second sub-exhaust channel 2021b) → fourth exhaust channel 20d → outside. This achieves the effect of balancing the internal and external pressures of the energy storage system 1000 when valve 20 is in the second valve opening position, and also achieves the effect of depressurizing the energy storage system 1000.

[0141] It is understood that in this embodiment of the application, the sealing ring 214 can ensure the sealing between the valve cover body 2021 and the valve seat 201 when the valve 10 is in the second valve opening position.

[0142] See Figure 9 and Figure 10 The valve cover 202 also includes a waterproof membrane 2023, located at the outlet of the second exhaust channel 204a of the valve stem 204. The waterproof membrane 2023 has good air permeability. On the one hand, it can prevent water from entering the energy storage system 1000. On the other hand, it can also play a role in ventilation. Gas in the second exhaust channel 204a of the valve stem 204 can enter the valve cover body space 202c through the waterproof membrane 2023 and finally be discharged to the outside, balancing the internal and external pressure of the energy storage system 1000.

[0143] The third exhaust passage 202b of the valve cover 202 can work in conjunction with the first exhaust passage 20a between the valve cover 202 and the valve seat 201 to improve exhaust efficiency, and exhaust can be achieved by utilizing the structure of the valve 20 itself without the need to add an additional drainage passage.

[0144] When valve 20 is in the second valve opening position, the third exhaust channel 202b can be connected to the outside of the energy storage system 1000 through the fourth exhaust channel 20d to improve exhaust efficiency and balance the internal and external air pressure of the energy storage system 1000.

[0145] The principle of valve 20 in this embodiment will be explained below with an example. In this example, the device to be woken up 40 is a BMS400, the wake-up power supply 10 is a low-voltage power supply, the reset member 210 is a columnar spring, the conductive member 203 is a conductive block, the conductive action member 215 is a conductive spring, the insulating connector 205 is an insulating sheet, one second external conductive member 3002 is a first conductive wire harness, another second external conductive member 3002 is a second conductive wire harness, one first external conductive member 3001 is a first conductive sheet, one first external conductive member 3001 is a second conductive sheet, and the wake-up power supply 10 is an external low-voltage power supply. The insulating sheet is located between the conductive block and the first conductive sheet.

[0146] The first conductive harness connects to an external low-voltage power supply, and the second conductive harness connects to the low-voltage power supply interface of the BMS400. In the absence of thermal runaway, the conductive block and the first conductive sheet are separated by the insulating sheet, and the first and second conductive harnesses are in an open-circuit state. When the battery 300 triggers thermal runaway, the internal pressure of the energy storage system 1000 increases. The high-pressure gas pushes the valve cover 202 away from the valve seat 201 (i.e., moving along the X2 direction), compressing the columnar spring. Simultaneously, the valve cover 202 drives the valve stem 204 and the insulating sheet to move closer to the valve seat 201 (i.e., moving along the X2 direction). At the same time, the conductive block, under the action of the conductive spring, moves along the second direction towards the conductive sheet on one side (i.e., the Y1 direction). After the conductive block contacts the first conductive sheet, the conductive spring maintains its connection with the second conductive sheet. Thus, the first and second conductive sheets are connected, the external low-voltage power supply is turned on to the BMS400, and the BMS400 is activated.

[0147] According to the second aspect of this application, please refer to Figure 19 and Figure 20 , Figure 19 This is a flowchart of a wake-up control method provided in an embodiment of this application. The wake-up control method in this example is applied to a wake-up device, which includes a valve 20 and a power supply wake-up device. The valve and power supply wake-up device in this example are the aforementioned valve and power supply wake-up device; their specific structures are not described in detail here. The valve is configured to have a first valve opening degree and is connected between the wake-up power supply and the power supply wake-up device. Figure 20 As shown, the wake-up control method may include the following step S60.

[0148] Step S60: When the valve is in the first valve opening position, the power supply wake-up device is in the conducting state to wake up the device to be woken up and execute the preset function.

[0149] As mentioned above, the power supply wake-up device is in the conduction state, which enables the wake-up power supply to interact with the device to be woken up, so as to wake up the device to perform preset functions.

[0150] By coordinating the valve and the power supply wake-up device, the electrical energy interaction between the wake-up power supply and the device to be woken up is realized. The mechanical characteristics of the valve enable the power supply wake-up device to conduct, thereby realizing the electrical energy interaction between the device to be woken up and the wake-up power supply. There is no need to set up a separate sensor to identify the valve status and transmit sensor signals, which effectively reduces the structural complexity of the energy storage system.

[0151] In some embodiments, step S60 can be implemented by the following steps: Step S61: When the valve is in the first valve opening position, the first external conductive component and the second external conductive component are connected through the valve to make the power supply wake-up device in the conducting state.

[0152] The first external conductive component and the second external conductive component are connected through a valve to put the power supply wake-up device in a conductive state. This means that the first external conductive component and the second external conductive component are connected through conductive components to form a current flow path. In this way, the current flow path between the wake-up power supply and the device to be woken up (i.e., BMS) is also connected, and the two realize electrical energy interaction to wake up the device to be woken up (i.e., BMS) to perform fault operation and avoid thermal runaway of the battery pack.

[0153] In some embodiments, please refer to Figure 21 , Figure 20 This is a flowchart of another wake-up control method provided in an embodiment of this application. The wake-up control method further includes step S70.

[0154] Step S70: When the valve is in the second valve opening position, the power supply wake-up device is in the off state so that the wake-up power supply and the device to be woken up are disconnected from the power interaction.

[0155] When the power supply wake-up device is in the off state, it means that the valve moves away from the valve seat in the first direction from the open position to disconnect the electrical connection between the first external conductive component and the second external conductive component. The current flow path between the two is disconnected, thus disconnecting the current flow path between the wake-up power supply and the device to be woken up (i.e., BMS), and the two disconnect the electrical energy interaction.

[0156] Disconnecting the power exchange between the wake-up power supply and the device to be woken up (i.e., BMS) does not mean that the device to be woken up (i.e., BMS) enters a sleep state. The device to be woken up (i.e., BMS) can be in working state and perform corresponding fault operations (such as performing battery cooling operations).

[0157] Understandably, when the valve switches from the first valve opening to the second valve opening, meaning the device to be woken up (i.e., the BMS) has been woken up and completed the fault operation, even if the internal air pressure of the battery pack has not reached the first air pressure threshold, the device to be woken up (i.e., the BMS) will not directly enter a sleep state after completing the fault operation. This is because, after the device to be woken up (i.e., the BMS) completes the fault operation, the battery temperature may not be at its optimal operating temperature (the optimal operating temperature can be a specific temperature value or a range). Therefore, the device to be woken up (i.e., the BMS) will continue to cool the battery to bring it back to its optimal operating temperature.

[0158] In some embodiments, step S70 can be implemented by the following steps: Step S71: When the valve is in the second valve opening position, the first external conductive component is disconnected from the second external conductive component so that the power supply wake-up device is in the off state.

[0159] It should be noted that steps S61 and S71 in the embodiments of this application can be executed alternately.

[0160] For example, in the initial stage, the valve is in the second valve opening position. When the air pressure in the battery pack gradually increases or rapidly increases to the first air pressure threshold, the valve cover moves along the first direction under the action of air pressure, thereby driving the valve stem, insulating connector, and conductive component to move along the first direction. The conductive component can move to a position where it is connected to the first and second external conductive components. In this way, the first and second external conductive components can be connected. Thus, the connection between the first and second external conductive components enables the power supply wake-up device to be in a conductive state, realizing the power exchange between the wake-up power supply and the device to be woken up (i.e., BMS), waking up the device to be woken up (i.e., BMS) to perform the corresponding fault operation.

[0161] As the device to be woken up (i.e., BMS) malfunctions, in step S71, after the air pressure in the battery pack gradually decreases from the first air pressure threshold, under the bias pressure provided by the reset component, the valve stem and valve cover can move towards the valve seat in the first direction. The insulating connector is inserted between the conductive component and one of the external conductive components, thereby enabling the conductive component to move from the conducting position to the disconnected position in the second direction, so that the conductive component and one of the external conductive components are electrically isolated. The valve is in the second valve opening, and the connection between the first external conductive component and the second external conductive component is disconnected. The power interaction between the wake-up power supply and the device to be woken up (i.e., BMS) is disconnected, avoiding continuous power consumption of the wake-up power supply.
