The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.
[0045] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.
[0046] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.
[0048] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).
[0049] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.
[0050] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.
[0051] Battery cells can be cylindrical, flat, cuboid, or other shapes, and this application embodiment is not limited to any of these. Battery cells are generally classified into three types according to their packaging method: cylindrical battery cells, square battery cells, and pouch battery cells, and this application embodiment is not limited to any of these types either.
[0052] A battery cell includes a casing, electrode components, and electrolyte. The casing houses the electrode components and electrolyte. The electrode components consist of a positive electrode, a negative electrode, and a separator. The battery cell primarily functions by the movement of metal ions between the positive and negative electrode components.

[0053] The separator can be made of PP (polypropylene) or PE (polyethylene), etc. Furthermore, the electrode assembly can be a wound structure or a stacked structure; the embodiments of this application are not limited to these.
[0054] The technical solutions described in the embodiments of this application are applicable to various electrical devices that use individual battery cells, such as mobile phones, portable devices, laptops, electric vehicles, electric toys, power tools, vehicles, ships, and spacecraft, including aircraft, rockets, space shuttles, and spacecraft. Individual battery cells are used to store or provide electrical energy.
[0055] The battery apparatus mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells connected in series, parallel, or mixed connections via a busbar.
[0056] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells.
[0057] As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form an independent module. As another example, a battery module can be formed by bundling multiple battery cells together with cable ties.
[0058] In some embodiments, the battery device may be a battery pack, which includes a housing and one or more individual battery cells housed within the housing.
[0059] As an example, the battery cell assembly can be a battery module, and the battery cell assembly can be housed in the housing by fixing the battery module in the housing.
[0060] As an example, battery cell assemblies can also be housed in a housing by directly fixing multiple battery cells to the housing.
[0061] As an example, the enclosure may include a first enclosure and a second enclosure. The first enclosure and the second enclosure are fastened together to form a closed space inside the enclosure to house the individual battery cells. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first enclosure may be a top cover or a bottom plate.
[0062] As an example, the enclosure may include a top cover, a frame, and a bottom plate. The top cover and bottom plate are connected to the frame, creating an enclosed space inside the enclosure to house the individual battery cells.
[0063] In some embodiments, the housing may be part of the vehicle's chassis structure. For example, a portion of the housing may be at least a part of the vehicle's floor, or a portion of the housing may be at least a part of the vehicle's crossbeams and longitudinal beams.
[0064] The technical solutions described in the embodiments of this application are applicable to various electrical devices that use battery devices, such as mobile phones, portable devices, laptops, electric vehicles, electric toys, power tools, vehicles, ships, and spacecraft, etc. For example, spacecraft include airplanes, rockets, space shuttles, and spacecraft. The battery device is used to store or provide electrical energy.
[0065] The inventors discovered that in scenarios such as testing or training battery devices, devices with physical buttons are typically used to generate simulated commands to trigger the battery to output power. For example, a CAN communication signal generator includes a CAN communication module, a microcontroller module, an SD card storage module, a button module, a display module, and a step-down module. The SD card storage module, display module, and step-down module are all electrically connected to the microcontroller module. The step-down module is electrically connected to the input power supply via a connecting cable. The microcontroller module is signal-connected to the CAN line via the CAN communication module. The microcontroller module has eight buttons (potentiometer knobs) labeled A, B, C, D, E, F, G, and H, expandable up to a maximum of 16 knobs. Devices including the aforementioned CAN communication signal generator need to pre-write data into their memory. By operating the knobs or buttons, output signals corresponding to the stored data are generated, thereby triggering the Electronic Control Unit (ECU) to send commands.
[0066] However, the use of devices including the aforementioned CAN communication signal generator is rather inconvenient, and the method of modifying data is not flexible enough and is quite cumbersome. When data modification is required, the device needs to be connected to a host computer to modify the data stored in its memory. Therefore, additional hardware is required, including data cables, a CAN (Controller Area Network) box, a computer, and a host computer. Furthermore, to connect or use the data cables, CAN box, computer, and host computer, the device needs to have external or reserved interfaces, affecting the overall appearance and aesthetics of the device.
[0067] Based on the above considerations, and in order to solve the problem of inconvenient use of devices for triggering battery device output in scenarios such as testing or training of battery devices, the inventors, after in-depth research, designed a battery triggering device, including an input device and a message generation device; the message generation device includes a wireless communication module and a control module; the wireless communication module is wirelessly connected to the input device; the wireless communication module is used to acquire target data sent by the input device; the message generation device is connected to the wireless communication module; the message generation device is used to generate a target signal based on the target data and output the target signal to the management device of the target battery device; the target signal is used to trigger the target battery device to output electrical energy.
[0068] Based on this structure of the battery-triggered device, different target data can be sent to the message generator through the input device, making it easier to modify the data and improve the convenience of using the battery-triggered device. Furthermore, it is possible to wirelessly modify, store, or delete the data sent by the message generator without ensuring safety or making any changes to the wiring harness or disassembly, thereby achieving specific functions.
[0069] The battery triggering device, teaching aid, and testing system according to embodiments of this application are described below with reference to Figures 1-9.
[0070] Referring to Figure 1, a battery triggering device 100 includes an input device 110 and a message generating device 120; the message generating device 120 includes a wireless communication module 121 and a control module 122.
[0071] In practical implementation, the battery triggering device 100 provided in this application embodiment can be used to simulate triggering of a target battery device. The target battery device can be any type of battery device. The battery device can be a power battery or an energy storage battery, etc. The battery device may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells, which are connected in series, parallel, or mixed connections via a busbar component.
[0072] The input device 110 and the message generating device 120 are separate structures, and the input device 110 and the message generating device 120 can communicate and connect wirelessly.
[0073] The input device 110 can be used for user input of target data. The message generating device 120 can generate a target signal to trigger the target battery device to output electrical energy based on the target data input by the user. The target data may include message information corresponding one-to-one with the message generating device 120.
[0074] In some embodiments, the input device 110 may include a display, a keyboard, and / or a mouse. The display may show a graphical user interface (GUI). Based on the GUI, users can more conveniently input data using a keyboard and / or mouse. In some embodiments, the keyboard may include a virtual keyboard and / or a physical keyboard. In some embodiments, the mouse may include a virtual mouse and / or a physical mouse.
[0075] In some embodiments, data for generating target signals by message generation device 120 can be modified and saved by inputting data through input device 110, thereby solving the problem of rewriting and saving data.
[0076] In some embodiments, the message generating device 120 may include a wireless communication module 121 and a control module 122. The wireless communication module 121 can wirelessly communicate with the input device 110, thereby receiving data input by the user through the input device 110. The control module 122 can generate a signal to trigger the target battery device to output power based on the data input by the user.
[0077] The wireless communication module 121 is wirelessly connected to the input device 110; the wireless communication module 121 is used to acquire target data sent by the input device 110.
[0078] In actual implementation, the wireless communication module 121 and the input device 110 can communicate wirelessly.
[0079] In some embodiments, the wireless communication module 121 may include at least one of the following: Wi-Fi module, Bluetooth module, Zigbee module, 5G (5th Generation Mobile Communication Technology) module, NB-IoT (Narrow Band Internet of Things) module, and LoRa (Long Range Radio) module.
[0080] For example, the wireless communication module 121 may include a Wi-Fi module. The Wi-Fi module can be used for complete and self-contained Wi-Fi network functionality. The Wi-Fi module can integrate an antenna switch, a radio frequency balun, a power amplifier, a low-noise amplifier, a filter, and a power management module. The Wi-Fi module can achieve rapid switching between sleep and wake-up modes and adaptive radio frequency adjustments for low-power operation, thus achieving energy saving. The Wi-Fi module can have fault diagnosis and radio frequency coexistence mechanisms to eliminate interference from cellular communication signals, Bluetooth signals, DDR (Double Data Rate Synchronous Dynamic Random Access Memory), LVDS (Low-Voltage Differential Signaling), and LCD (Liquid Crystal Display) signals. The Wi-Fi module supports the TCP / IP protocol and fully complies with the 802.11b / g / n WLAN MAC protocol. It supports Basic Service Set (BSS) STA operation and SoftAP operation under the Distributed Coordination Function (DCF). The Wi-Fi module can optimize effective operating time by minimizing host interaction to achieve power management.
[0081] In some embodiments, the structure of the Wi-Fi module can be as shown in Figure 2. Figure 2 shows the main pins and peripheral circuitry of the Wi-Fi module. Here, 3.3V indicates that the input voltage of the Wi-Fi module is 3.3V, but those skilled in the art will understand that the input voltage of the Wi-Fi module can be other values. Figure 2 also shows the numbers and parameters of components such as capacitors and resistors in the Wi-Fi module; for example, C15 and R7 are the component numbers, and 475 and 10K are the capacitance and resistance values, respectively.
[0082] In some embodiments, after the message generating device 120 is powered on, the wireless communication module 121 can generate a wireless signal (e.g., a Wi-Fi module generates a Wi-Fi signal or a 5G module generates a 5G signal), and the input device 110 can connect to the message generating device 120 based on the aforementioned wireless signal.
[0083] In some embodiments, the message generating device 120 may have a connection verification function to verify the devices connected to it in order to ensure security.
[0084] The control module 122 is connected to the wireless communication module 121; the control module 122 is provided with a wired communication interface for connecting to the management device 130 of the target battery device; the control module is used to generate a target signal based on the target data and output the target signal to the management device; the target signal is used to trigger the target battery device to output electrical energy.
[0085] In actual operation, the control module 122 can be connected to the wireless communication module 121 via wired or wireless means, so that target data can be transmitted to the control module 122 through the wireless communication module 121.
[0086] In some embodiments, the control module 122 may be housed in the same housing as the wireless communication module 121.
[0087] The control module 122 may include a wired communication interface. This wired communication interface allows connection between the message generating device 120 and the management device of the target battery device. The management device of the target battery device may be a BMS or a BMU.
[0088] The control module 122 can convert the target data into a target signal. The target signal can conform to the communication protocol used by the wired communication interface. In some embodiments, the target signal is an extended frame or a standard frame. The extended frame or standard frame signal can have different baud rates and / or conform to different protocols. In some embodiments, the extended frame can be an extended frame commonly used in related technologies, and the standard frame can be a standard frame commonly used in related technologies.
[0089] It is understandable that the input device 110 can modify and save instruction data, thereby realizing the modification and saving of target data, thus solving the problem of inconvenient data rewriting and saving in related technologies.
[0090] The specific type of the communication protocol described above is not limited in the embodiments of this application. For example, the communication protocol can be the CAN protocol, and the target signal can be two analog CAN signals (which can be denoted as CANH and CANL, or CAN-H and CAN-L, respectively); or the communication protocol can be the Local Interconnect Network (LIN) protocol, and the target signal can be a LIN signal.
[0091] Understandably, after receiving the target signal transmitted by the message device, the battery management system can control the target battery to receive high voltage and output electrical energy, thereby meeting the high voltage requirement of the target battery, provided that the power-on conditions are met.
[0092] Understandably, after the target battery is powered on at high voltage, the functional integrity of the high-voltage contactor and other devices can be monitored.
[0093] According to the battery triggering device provided in this application embodiment, the input device is wirelessly connected to the wireless communication module of the message generator. The target data input by the input device is transmitted to the control module of the message generator through the wireless communication module. Based on the target data, the control module generates a target signal and outputs the target signal to the management device of the target battery device to trigger the target battery device to output power. This eliminates the need for expensive and bulky wiring harnesses, resulting in a simpler and more aesthetically pleasing layout. It eliminates the need for external or reserved interfaces, leading to a more attractive overall device appearance and easier and faster fault diagnosis and repair. Under the premise of ensuring safety and without any changes to the wiring harness or disassembly, a simple and compact message generator, in conjunction with a dedicated input device, can wirelessly modify, store, and delete the data transmitted by the message generator to achieve specific functions. Data modification is simpler, more convenient, and more flexible, making the entire device more convenient to use. Furthermore, by using the message generator, the connection of components such as the drive system, vehicle controller, and DC / DC converter can be reduced, lowering the failure rate during device power-on or use and reducing safety risks during high-voltage power-on of the battery device.
[0094] In some embodiments, the control module 122 includes a controller 1221 and a transceiver 1222.
[0095] In actual implementation, the control module 122 can be composed of a controller 1221 and a transceiver 1222, etc.
[0096] The controller 1221 is connected to the wireless communication module 121; the controller 1221 is used to generate target messages based on target data.
[0097] In actual operation, the controller 1221 and the wireless communication module 121 can be connected by wired or wireless means to obtain the target data sent by the input device 110.
[0098] After the controller 1221 acquires the target data, it can process the target data and assemble the target message based on the target data.
[0099] In some embodiments, the controller 1221 may be a device with data processing capabilities, such as a CPU (Central Processing Unit) or an FPGA (Field Programmable Gate Array).
[0100] In some embodiments, the controller 1221 may employ any type of CPU.
[0101] For example, the controller 1221 can use the CPU shown in Figure 3. Figure 3 shows the main pins and peripheral circuitry of the CPU. Here, 3.3V indicates that the input voltage of the CPU module is 3.3V, but those skilled in the art will understand that the input voltage of the CPU module can be other values. Figure 3 also shows the numbers and parameters of components such as capacitors and resistors in the CPU; for example, C80 and R100 are the component numbers, and 22P and 10K are the capacitance and resistance values, respectively.
[0102] This CPU can use a 32-bit RISC (Reduced Instruction Set Computer) core, with a maximum operating frequency of 72MHz. It can also integrate high-speed memory and employ prefetching to improve instruction access speed. The CPU's system architecture allows multiple buses to operate synchronously, and it provides rich peripheral functions and enhanced I / O ports. Furthermore, the CPU can integrate a 12-bit ADC (Analog-to-Digital Converter) module (e.g., an ADC module with a conversion time of less than 1μs), a 12-bit DAC (Digital-to-Analog Converter) module, four 16-bit general-purpose timers, and multi-channel touch button capacitive sensing (TKey), among other devices or functions. The CPU may also include at least one of the following standard communication interfaces: I2C (Inter-Integrated Circuit) interface, SPI (Serial Peripheral Interface) interface, USART (Universal Synchronous / Asynchronous Receiver / Transmitter) interface, CAN interface, and USB 2.0 full-speed interface (for full / low-speed communication).
[0103] The CPU's core, DMA (Direct Memory Access) module, and SRAM (Static Random-Access Memory) interact through multiple buses. The CPU can also be configured with a Flash access prefetch mechanism to accelerate code execution and integrate a general-purpose DMA controller to reduce CPU load and improve efficiency. Furthermore, the CPU can utilize a multi-level clock management mechanism to reduce peripheral workload, while incorporating data protection and clock switching protection mechanisms to enhance system stability.
[0104] The transceiver 1222 can be connected to the CPU via a CAN interface for data transmission and control. The wireless communication module 121 can be connected to the CPU via a USART interface for data transmission and control.
[0105] Transceiver 1222 is connected to controller 1221; transceiver 1221 is used to convert target messages into target signals.
[0106] In actual operation, the controller 1221 can also be connected to the transceiver 1222 via wired or wireless means to output the target message to the transceiver 1222.
[0107] Transceiver 1222 can convert received target messages into target signals of extended frames or standard frames according to its own communication protocol. Transceiver 1222 can also be connected to the management device of the target battery device through a wired communication interface (such as a CAN interface or a LIN interface) to output the aforementioned target signals to the management device of the target battery device.
[0108] In some embodiments, transceiver 1222 can be a CAN transceiver. A CAN transceiver is typically in the form of a CAN transceiver chip. Using a CAN transceiver can improve the stability of the CAN signal and the transmission distance.
[0109] In some embodiments, the aforementioned CAN transceiver chip can be a high-speed CAN transceiver chip with isolation. This chip serves as an interface between the CAN protocol controller and the physical bus, enabling differential signal transmission between the bus and the CAN protocol controller. All necessary CAN isolation and CAN transceiver components can be integrated internally. The chip is fully compliant with the ISO 11898 standard and interoperable with other CAN transceiver products that conform to the ISO 11898 standard. In some embodiments, the chip also conforms to AEC-Q100 certification, has built-in over-temperature and over-current protection, allows at least 110 nodes to connect to the bus, and can achieve speeds up to 1 Mbps.
[0110] For example, a CAN transceiver chip can use the CPU shown in Figure 4. Figure 4 shows the main pins and peripheral circuitry of this CAN transceiver chip.

[0113] In actual operation, the battery-triggered device can be powered internally by a power supply device 140 with the ability to store or output electrical energy, which supplies power to the message generator 120. It is understood that the power supply device 140 can be connected to the message generator 120 via a power cord to supply power and ensure the normal operation of the message generator 120.
