Description

Technical Field

[0001] The present application belongs to the technical field of energy storage systems, and in particular, relates to an energy storage system, a fault handling method, an electronic device, and a storage medium. Background Art

[0002] The safety of energy storage systems has always been a research focus, and the most critical safety issue of energy storage systems is the protection against thermal runaway and thermal spread. Since the problem of thermal runaway and thermal spread of energy storage systems has always existed, this problem restricts the development of energy storage systems. In related technologies, each energy storage unit communicates with the control unit through a single link, reports detection information through a single link, monitors each energy storage unit for faults based on the detection information, and handles the faulty energy storage unit in a timely manner through monitoring. Since the related technology uses a single link for communication, when there is a problem with the single link, the fault information cannot be reported in time, resulting in untimely fault handling, leading to thermal runaway and thermal spread of the entire energy storage system. In addition, in order to prevent and protect against thermal runaway and thermal spread, related In the technology, however, protection and protection are mainly carried out through heat insulation and short-time fire extinguishing design. For example, by adding technologies such as heat insulation materials to solve the safety problems of energy storage systems, but this method has weak effects and affects product performance (such as poor heat dissipation and larger size). For the built-in fire extinguishing device technology, a fire extinguisher is installed in the product, but installing a fire extinguisher in the product will affect the product design (such as safety regulations, size, appearance, cost control, etc.); and the fire extinguishing device can only play a role in a short period of time at the early stage of thermal runaway. In addition, the built-in fire extinguishing assembly involves environmental protection and other issues. The existing design can only passively play a limited isolation or protection role in the early stage of an accident, and cannot provide active and long-term effective high-security protection to disconnect and isolate the faulty unit from the normal working unit.

[0041] Based on the technical problems of related technologies, an embodiment of the present application provides an energy storage system, including: multiple energy storage units and a main control module, wherein two adjacent energy storage units are communicatively connected, and each energy storage unit is communicatively connected to the main control module, each energy storage unit includes a detection module, each detection module is used to detect detection information corresponding to each energy storage unit, and transmit the detection information to the main control module, and the main control module is used to perform detection and control based on the detection information corresponding to each energy storage unit.

Figure 1 As shown, there may be multiple energy storage units, energy storage unit A, energy storage unit B, energy storage unit C...energy storage unit N, and the communication connection between each energy storage unit includes: it may be a communication link for fault monitoring and processing signal transmission, and a fault monitoring signal transmission path 1 and a fault processing signal transmission path 1 are provided between each energy storage unit and the main control unit.

[0043] In the embodiment of the present application, the energy storage unit is a basic component of the energy storage system, which is used to store and release energy. The energy storage unit can be a battery pack, a supercapacitor pack, a flywheel energy storage device, etc. The main control module is the core control part of the energy storage system, which is responsible for receiving detection information from each energy storage unit and monitoring and controlling the energy storage system as a whole based on this information. The main control module can be a controller of the energy storage system, and the controller can be an electronic device. The electronic device is responsible for data processing and decision-making, the communication interface is used to communicate with the energy storage unit and other system components, and the storage unit is used to store system parameters, historical data, etc. The detection module is a component in the energy storage unit, which is used to detect the operating status of the energy storage unit in real time and transmit the detection information to the main control module. The detection module usually includes a sensor, which is responsible for collecting physical quantities such as voltage, current, temperature, gas, pressure, sound and light of the energy storage unit, and transmitting it to the main control module. The sensor can be a Hall sensor, a thermistor, a temperature sensor, a pressure sensor, a gas sensor, a sound and light sensor, etc. In the embodiment of the present application, the communication connection refers to the communication link established between two adjacent energy storage units and between the energy storage unit and the main control module. These communication links are used to transmit data such as detection information and control instructions to achieve information sharing and control coordination within the energy storage system. Communication connections can be achieved by wired or wireless methods. Wired methods include CAN bus, RS485, Ethernet, etc., and wireless methods include Wi-Fi, Bluetooth, Zigbee, etc.

[0044] In the embodiment of the present application, control refers to the scheduling and management operations performed by the main control module on the energy storage unit according to the detection information, such as charge and discharge control, balance control, protection control, etc. The main control module monitors and evaluates the operating status of the energy storage system in real time by receiving the detection information. When an abnormal state is detected, the main control module will take corresponding control measures to intervene to ensure the safe and stable operation of the energy storage system.

[0045] The energy storage system provided in the embodiment of the present application can ensure that detection information can be reported in a timely manner by realizing multi-link communication by setting a communication connection between two adjacent energy storage units in the energy storage system, and each energy storage unit is communicated with a main control module.

[0046] In some embodiments, each energy storage unit is provided with a cable interface, and a cable is provided between two adjacent energy storage units. The cables include at least: a communication cable and a cable for transmitting power. The cables between two adjacent energy storage units are connected via the cable interface. The energy storage system further includes: a connection and separation device, which is arranged on each energy storage unit, each connection and separation device corresponds to a cable interface, and is communicatively connected with the main control module and each energy storage unit, and each connection and separation device is used to receive control from the main control module and / or the energy storage unit where it is located to separate the corresponding cable from the cable interface.

[0047] In the embodiment of the present application, the cable interface is a component on the energy storage unit for connecting the cable. It is usually designed with a standardized interface form so as to connect with different types of cables. The cable interface can be located on the side, top or bottom of the energy storage unit. Exemplarily, the cable interface is located on the side of the energy storage unit.

[0048] Communication cables are used to transmit control signals and data information to ensure information synchronization and coordination between energy storage units; power cables are used to transmit electrical energy to achieve energy sharing and distribution between energy storage units. The connection and separation device is a mechanical or electronic device arranged on the energy storage unit, which is used to achieve the separation between the cable and the cable interface. The connection and separation device can disconnect the connection cable according to the control instruction of the main control module or the energy storage unit. Taking the electronic device as an example, the electronic device can be an electronic hydraulic element. When the cable interface is connected to the cable on the energy storage unit, one end of the electronic hydraulic element abuts against the cable. When the control instruction is issued by the main control module, the hydraulic component of the electronic hydraulic element works to separate the cable from the cable interface. When the connection and separation device is a mechanical device, the mechanical device can include a spring, and the main control device can control the spring to bounce and separate the cable from the cable interface. Figure 2 A schematic diagram of the location of a connection and separation device provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the connection and separation device 200 can also be arranged on the side of the energy storage unit 100 and adjacent to the cable interface.

[0049] The energy storage system provided in the embodiment of the present application is provided with a connection and separation device, which can remove the cable from the cable interface. When a fault occurs, the connection between different energy storage device units can be disconnected, and the electrical circuit connection can be fundamentally disconnected, which can effectively avoid the failure of a single or local energy storage device (such as high temperature, short circuit, heat spread, etc.).

[0050] In some embodiments, there are multiple types of cables, and there are multiple cable interfaces, and one end of each type of cable corresponds to a cable interface. In this design, each connection and separation device corresponds to a cable interface, so multiple connection and separation devices need to be provided.

[0051] In order to save costs and make the separation function of the connection separation device more reliable, in some embodiments, there are multiple cables, and the multiple cables are integrated together, and one end of the integrated cable corresponds to a cable interface integrating multiple interfaces.

[0052] In the embodiment of the present application, in order to improve the neatness, reliability and maintainability of the system, these different types of cables can be integrated together to form a unified cable bundle or cable assembly. This integration method can reduce the number of cables, reduce the complexity of the system, and facilitate wiring and management. And by integrating the various cables together, when separating through the connection and separation device, they can be separated as a whole, thereby improving the reliability during separation.

[0053] In some embodiments, the energy storage system further includes: an isolation device, the isolation device is arranged on each energy storage unit, each isolation device corresponds to a cable interface, the isolation device is communicatively connected with the main control module and each energy storage unit, and each isolation device is used to receive the control of the main control module and / or the energy storage unit where it is located to move so as to close the cable interface corresponding to each isolation device. In the embodiment of the present application, the main function of the isolation device is to close the cable interface when necessary, and the isolation device is designed to be movable, and the movement can be achieved by a mechanical mechanism (such as a slide rail, a hinge, etc.) or an electric drive device. After receiving the control command from the main control module or the energy storage unit where it is located, the isolation device can automatically move to a specified position to close or open the cable interface.

[0054] In the present application, see Figure 2 The isolation device can also be arranged on the side of each energy storage unit and adjacent to the cable interface.

[0055] In the embodiment of the present application, when the main control module or the energy storage unit needs to close a certain cable interface, a control instruction is sent to the corresponding isolation device. After receiving the instruction, the isolation device performs a corresponding movement action according to the instruction requirements, and the isolation device moves to the closed position.

[0056] In an embodiment of the present application, when a fault is detected in a certain energy storage unit, in order to avoid the impact of the energy storage unit on other energy storage units, the cable interface connected to the unit can be closed by controlling the isolation device to prevent the fault from spreading to other units.

[0057] Based on the aforementioned energy storage system, the present application embodiment provides a fault handling method that can be applied to electronic devices such as mobile phones, tablet computers, wearable devices, augmented reality (AR) / virtual reality (VR) devices, laptop computers, ultra-mobile personal computers (UMPC), netbooks, personal digital assistants (PDA), etc. The present application embodiment does not impose any restrictions on the specific type of electronic devices, and the electronic device can be the main control module in the above energy storage system. The main control module can be the controller of the energy storage system.

[0058] The present application embodiment provides a fault handling method, which is described below by taking the main control module of an electronic device as an example. Figure 3 A schematic diagram of a troubleshooting method for implementing this application is shown in FIG. Figure 3 As shown, the troubleshooting methods include:

[0059] Step S101, acquiring detection information of each energy storage unit.

[0060] In the embodiment of the present application, the detection information may include: one or more of voltage, current, temperature, gas, pressure, sound and light, etc. The electronic device may communicate with the detection modules on each energy storage unit to obtain the detection information from each detection module.

[0061] Step S102: performing fault detection on each energy storage unit based on the detection information of each energy storage unit.

[0062] In the embodiment of the present application, the detection information can be analyzed according to the preset fault judgment rules and algorithms to determine whether there is a fault. The fault judgment rules may include threshold judgment rules, and the thresholds corresponding to the various detection parameters can be set. Fault detection is performed by comparing the thresholds corresponding to the various detection information. Taking the threshold judgment rules as an example, when gas, sound and light are detected, it can be considered that there is a fault. When the voltage, current, temperature, and pressure exceed the threshold, it is considered that there is a fault. If the voltage, current, temperature, and pressure are within the set threshold range, it is considered that there is no fault.

[0063] The detection method provided in the embodiment of the present application, by setting a communication connection between two adjacent energy storage units in the energy storage system, and each energy storage unit is communicated with the main control module, can realize multi-link communication, and can ensure that fault information can be reported in a timely manner, so that the fault can be detected in time, so that the fault can be prevented in time.

[0064] In some embodiments, the fault judgment rules may also include: trend analysis, pattern recognition and other methods. Trend analysis is a method of predicting or explaining phenomena by observing the changing trend of data over time. In fault judgment, trend analysis is usually used to monitor the operating status of equipment or systems and predict potential faults. Within a certain time range, by detecting the trend of data, the regular changes behind the data are discovered, and thus the fault is predicted through trend analysis. For example, if the temperature of a certain energy storage unit is far away from the trend, it is considered that there is a fault.

[0065] In some embodiments, after step S102, the method further includes:

[0066] Step S103, when it is determined based on the detection information that the target energy storage unit has a fault, controlling the connection and separation device on the target energy storage unit and / or the connection and separation device on the energy storage unit adjacent to the target energy storage unit to separate the target energy storage unit from the energy storage unit adjacent to the target energy storage unit.

[0067] In the embodiment of the present application, the target energy storage unit may be any energy storage unit in the energy storage system, and fault judgment rules and algorithms may be used to determine whether the energy storage unit has a fault. If a fault is determined, the energy storage unit is the target energy storage unit.

[0068] In an embodiment of the present application, the main control module can send a control instruction to the connection and separation device on the target energy storage unit to activate the connection and separation device. After receiving the instruction, the connection and separation device starts to act through an internal driving mechanism (such as a motor, an electromagnet, etc.). When the connection and separation device moves to a predetermined position, it separates the connection between the cable and the cable interface, thereby separating the target energy storage unit from the energy storage unit adjacent to the target energy storage unit.

[0069] In some embodiments, the main control module may also send a control instruction to the connection and separation device on the energy storage unit adjacent to the target energy storage unit to activate the connection and separation device, and after receiving the instruction, the connection and separation device starts to operate through an internal driving mechanism (such as a motor, an electromagnet, etc.). When the connection and separation device moves to a predetermined position, it disconnects the cable from the cable interface, thereby separating the target energy storage unit from the energy storage unit adjacent to the target energy storage unit.

[0070] In some embodiments, the main control module can also simultaneously send control instructions to the connection and separation device on the target energy storage unit and to the connection and separation device on the energy storage unit adjacent to the target energy storage unit, thereby separating the target energy storage unit from the energy storage unit adjacent to the target energy storage unit.

[0071] In the embodiment of the present application, the connection and separation device can also feedback status information, and the status information includes: whether the separation is successful and whether there is a fault, etc. If there is a fault, an alarm signal can be output.

[0072] The method provided in the embodiment of the present application, when it is determined based on the detection information that a target energy storage unit has a fault, controls the connection and separation device on the target energy storage unit and / or the connection and separation device on the energy storage unit adjacent to the target energy storage unit to separate the target energy storage unit from the energy storage unit adjacent to the target energy storage unit, thereby disconnecting the connection between the faulty energy storage units and fundamentally disconnecting the electrical circuit connection, which can effectively avoid the fault of a single or local energy storage unit (such as high temperature, short circuit, heat spread, etc.) and fundamentally cut off the propagation of the fault in the electrical and communication connection circuits.

[0073] In some embodiments, after step S103, the method further includes:

[0074] Step S104: Control the isolation device on the target energy storage unit and / or the isolation device on the energy storage unit adjacent to the target energy storage unit to isolate the target energy storage unit from the energy storage unit adjacent to the target energy storage unit.

[0075] In an embodiment of the present application, when it is determined that a certain target energy storage unit has a fault and needs to be isolated from the system, in addition to directly separating the connection between the cable and the cable interface, the isolation device on the target energy storage unit and / or the isolation device on the energy storage unit adjacent to the target energy storage unit is controlled to isolate the target energy storage unit from the energy storage units adjacent to the target energy storage unit to close the cable interface on the target energy storage unit, thereby isolating the target energy storage unit from the energy storage units adjacent to the target energy storage unit.

[0076] In the embodiment of the present application, the main control module can send a control instruction to the isolation device on the target energy storage unit. After receiving the control instruction, the driving mechanism (such as a motor, an electromagnet, a pneumatic device, etc.) inside the isolation device starts to move, pushing the isolation device to move along a preset track or path. When the isolation device moves to a predetermined position, it will form a physical closure or isolation with the cable interface.

[0077] In some embodiments, the main control module can send a control instruction to the isolation device on the energy storage unit adjacent to the target energy storage unit. The isolation device on the energy storage unit is close to the isolation device on the target energy storage unit. The driving mechanism (such as a motor, an electromagnet, a pneumatic device, etc.) inside the isolation device starts to move, pushing the isolation device to move along a preset track or path. When the isolation device moves to a predetermined position, it will form a physical closure or isolation with the cable interface, thereby isolating the target energy storage unit from the energy storage unit adjacent to the target energy storage unit.

[0078] In some embodiments, the main control module may also simultaneously send control instructions to an isolation device on a target energy storage unit and to an isolation device on an energy storage unit adjacent to the target energy storage unit, thereby isolating the target energy storage unit from the energy storage units adjacent to the target energy storage unit.

[0079] The method provided in the embodiment of the present application isolates the target energy storage unit from the energy storage units adjacent to the target energy storage unit by controlling the isolation device on the target energy storage unit and / or the isolation device on the energy storage unit adjacent to the target energy storage unit, so that the target energy storage unit forms an independent unit, thereby greatly improving the safety of the energy storage system.

[0080] Based on the foregoing embodiments, an embodiment of the present application provides an application scenario. During the operation of the energy storage system, when a target energy storage unit experiences thermal runaway, the cable can be separated from the cable interface by controlling the connection separation device and then isolated by an isolation device, thereby avoiding thermal runaway and improving the safety of the energy storage system.

[0081] In some embodiments, after step S102, the method further includes:

[0082] Step S105 : when it is determined based on the detection information that the target energy storage unit has a fault, determine the fault level based on the detection information.

[0083] In the embodiment of the present application, the fault level is the severity of the fault evaluated based on the detection information. The classification of fault levels can be formulated according to actual needs and system characteristics, and usually includes minor faults, serious faults, etc. By analyzing the detection information, such as abnormal changes in the detection information, the degree of fault of the energy storage unit can be evaluated and the fault level can be determined. For example, when sound, light, gas, etc. are detected, it can be considered that the degree of fault is high and the fault level is high. Different temperature, voltage, and current ranges can be set to correspond to different fault levels, and the fault level is determined by determining the ranges corresponding to the temperature, voltage, and current in the detection information.

[0084] In the embodiment of the present application, the fault level may include: a first fault level and a second fault level, the first fault level is lower than the second fault level, for example, the first fault level may be a minor fault, and the second fault level may be a major fault.

[0085] Step S106, when the fault level is the first fault level, controlling the connection and separation device on the target energy storage unit and / or the connection and separation device on the energy storage unit adjacent to the target energy storage unit to separate the target energy storage unit from the energy storage unit adjacent to the target energy storage unit.

[0086] In an embodiment of the present application, when it is determined that the target energy storage unit has a first fault level (minor fault), an instruction can be sent to the connection and separation device through the control system to cause it to perform a separation operation, thereby separating the cable connected to the target energy storage device from the corresponding cable interface, thereby separating the target energy storage unit from the energy storage unit adjacent to the target energy storage unit.

[0087] Step S107, when the fault level is the second fault level, controlling the connection and separation device on the target energy storage unit and / or the connection and separation device on the energy storage unit adjacent to the target energy storage unit to separate the target energy storage unit from the energy storage unit adjacent to the target energy storage unit, and controlling the isolation device on the target energy storage unit and / or the isolation device on the energy storage unit adjacent to the target energy storage unit to isolate the target energy storage unit from the energy storage unit adjacent to the target energy storage unit, wherein the fault degree of the first fault level is less than the fault degree of the second fault level.

[0088] In the embodiment of the present application, the control system can send an instruction to the connection and separation device to make it perform a separation operation to separate the cable from the corresponding cable interface, and then send an instruction to the isolation device to move it to a predetermined position and close the cable interface.

[0089] The method provided in the embodiment of the present application can improve the safety of the energy storage system by determining different fault levels to achieve different protection modes, multiple passive protection designs, and multiple active protection designs.

[0090] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
