[0176] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0177] With the application of Internet of Things (IoT) technology in the field of power tools, many devices of the garden team can achieve communication with user terminals by setting up communication modules, thereby realizing data interaction, so that users can monitor and manage the working status of the equipment through the user terminal. However, in the prior art, the communication method between the device and the user terminal is often relatively simple, either using a communication module that can achieve long-distance communication, or using a communication module that can communicate within a short distance. The long-distance communication method has high communication reliability, but the cost of the communication module is high, which affects the market competitiveness of the product; the short-distance communication method has low communication module cost, but low communication reliability, and the device cannot communicate with the user terminal when the communication distance is exceeded. Therefore, affected by the cost factor of the communication module, in actual applications, it is often difficult to give equal consideration to communication reliability and cost issues.

[0178] In order to solve the above technical problems, the present application provides a device component, which includes a battery pack and a device provided with a device wireless communication module. The device can be electrically connected to the battery pack and transmit power, the battery pack can communicate with the device, and the battery pack is provided with a battery pack wireless communication module.

[0179] The battery pack is configured with a first battery pack communication mode and a second battery pack communication mode. In the first battery pack communication mode, the battery pack data is directly transmitted to the user terminal (also known as a mobile terminal) via the battery pack wireless communication module. In the second battery pack communication mode, the device receives the battery pack data and transmits it to the user terminal via the device wireless communication module. The device wireless communication module is configured to enable data transmission between the device and the user terminal within a first preset communication distance, and the battery pack wireless communication module is configured to enable data transmission between the battery pack and the user terminal within a second preset communication distance, wherein the first preset communication distance is greater than the second preset communication distance.

[0180] By rationally configuring communication modules for battery packs and devices and rationally configuring the communication methods between battery packs and devices and user terminals, the communication reliability between the battery packs and devices and user terminals can be effectively improved, allowing users to effectively monitor and manage the battery packs and devices at a low cost.

[0181] It is understandable that the device can be configured as a charging device that can be electrically connected to a battery pack and charge the battery pack, or it can be configured as other devices that can be electrically connected to a battery pack and provided with electrical energy by the battery pack, such as an electric tool.

[0182] The battery pack 10 can at least serve as a power source for a power tool. In practical applications, the power tool can be any of a lawn mower, brush cutter, edger, pruning shears, high-pressure washer, hair dryer, chain saw, push mower, multi-task tool, sprayer, and, of course, other power tools that require independent power modules for power supply, which are not listed here. In the scenario shown in Figure 8, when the battery pack 10 is connected to the power tool, it can provide power to the connected power tool.

[0183] Referring to Figure 1 , one embodiment of the present application provides a device assembly, comprising a battery pack 10 and a device. The device is configured as a charging device, capable of electrically connecting to and charging the battery pack 10, and capable of communicating with the battery pack 10 (when the device is configured as a charging device, the device assembly constitutes an energy system). The charging device is provided with a device wireless communication module, and the battery pack 10 is provided with a battery pack wireless communication module 101.

[0184] Furthermore, the charging device communicates with the battery pack 10 through wired communication to receive data from the battery pack 10. Specifically, the battery pack 10 and the charging device are provided with matching wired communication modules. When the battery pack 10 and the charging device are connected, the two exchange data through wired communication. Specifically, the charging device is configured with a device wired communication module, and the battery pack 10 is configured with a battery pack wired communication module 102. Among them, the wired communication module described in this embodiment can be any one of a serial communication module and a CAN communication module. Of course, it can also be other forms of wired transmission modules, which also fall within the scope of protection of the present invention without exceeding the scope of the core idea of ​​the present invention. Preferably, the wired communication module between the charging device and the battery pack 10 adopts a serial communication module or a CAN communication module.

[0185] The battery pack 10 is configured with a first battery pack communication mode and a second battery pack communication mode. In the first battery pack communication mode, battery pack data is transmitted directly to the user terminal 30 via the battery pack wireless communication module 101. In the second battery pack communication mode, the charging device receives the battery pack data and transmits it to the user terminal via the first wireless communication module 201. The device wireless communication module is configured to enable data transmission between the charging device and the user terminal 30 within a first predetermined communication distance, while the battery pack wireless communication module 101 is configured to enable data transmission between the battery pack 10 and the user terminal 30 within a second predetermined communication distance, where the first predetermined communication distance is greater than the second predetermined communication distance.

[0186] In this embodiment, the device wireless communication module can be a wireless communication module that can realize long-distance communication, and the battery pack wireless communication module 101 can be a wireless communication module that can communicate within a short range. The charging device can communicate with the user terminal 30 over a long distance through the device wireless communication module, and the battery pack 10 can communicate with the user terminal 30 within a short range through the battery pack wireless communication module 101. Specifically, the device wireless communication module can be one of a 3G module, a 4G module, a 5G module, a Lora module, a sigfox module, and a NB-IOT module. The battery pack wireless communication module 101 can be one of a Bluetooth module, a Zigbee module, a sub-1G module, and an RF433 module. Preferably, in this embodiment, the device wireless communication module adopts a 4G module, and the battery pack wireless communication module 101 adopts a Bluetooth module.

[0187] In the above embodiment, the charging device can be configured as an energy storage charging device 20, or as a battery pack charger 50.

[0188] 4 and 5 , when the charging device is configured as an energy storage charging device 20, the device assembly includes a battery pack 10 and the energy storage charging device 20. The energy storage charging device 20 is capable of electrically connecting to and charging the battery pack 10, and the battery pack 10 is capable of communicating with the energy storage charging device. The energy storage charging device 20 is equipped with a first charging device wireless communication module 201 (i.e., the device wireless communication module of the charging device described above).

[0189] In the first battery pack communication mode, the battery pack data is directly transmitted to the user terminal 30 through the battery pack wireless communication module 101; in the second battery pack communication mode, the energy storage charging device 20 receives the battery pack data and transmits it to the user terminal through the first charging device wireless communication module 201.

[0190] Furthermore, the energy storage charging device 20 is also equipped with a charging device wired communication module 202 (i.e., the device wired communication module of the aforementioned charging device). When the battery pack wired communication module 102 of the battery pack 10 is connected to the charging device wired communication module 202 of the energy storage charging device 20, the battery pack 10 and the energy storage charging device 20 can exchange data via wired communication.

[0191] As an example, the first charging device wireless communication module 201 can be a 3G module, a 4G module, a 5G module, a LoRa module, a SigmaFox module, or a NB-IoT module. The battery pack wireless communication module 101 can be a Bluetooth module, a Zigbee module, a sub-1G module, or an RF433 module. Preferably, in this embodiment, the first charging device wireless communication module 201 uses a 4G module, and the battery pack wireless communication module 101 uses a Bluetooth module.

[0192] The energy storage charging device 20 is usually used as a portable charging power source. The energy storage charging device 20 includes a battery module 210 and a charging module 220. The charging module 220 is provided with a charging interface 222. The battery module 210 is electrically connected to the charging module 220. The charging module 220 is at least used to convert the electrical energy of the battery module 210 and output the electrical energy to the outside through the charging interface 222 to charge the battery pack 10 connected to the charging interface 222. As shown in the scenario in Figure 6, for example, the battery pack 10 can be a handheld battery pack 10a, a backpack battery pack 10b, or other forms. It can be understood that the energy storage charging device 20, by providing the battery module 210, makes the charging process of the battery pack 10 no longer rely on the AC power supply, thereby meeting the power needs of the garden team during outdoor operations.

[0193] Specifically, the battery module 210 of the energy storage charging device 20 is detachably connected to the charging module 220. The charging module 220 is provided with a charging module housing 221, which also includes a first charging module 223, a second charging module 224, and an AC input interface 225. The charging interface 222 includes a first charging interface 222a, a second charging interface 222b, and a third charging interface 222c. The first charging interface 222a, the second charging interface 222b, and the third charging interface 222c are all provided on the charging module housing 221. Specifically, the first charging interface 222a, the second charging interface 222b, and the third charging interface 222c can each be connected to the battery pack 10 to charge the battery pack 10. Furthermore, the third charging interface 222c can also be connected to an inverter to output AC power to adapt to devices that require AC power. The third charging interface can also be connected to an adapter to charge devices with different charging interfaces. For example, as shown in Figure 7, the third charging interface 222c can be connected to the adapter 228 to charge the garden robot tool 60. Specifically, the adapter 228 includes a first interface 228a, a second interface 228b, and a first cable 228c connecting the first and second interfaces 228a, 228b. The first interface 228a is configured to interface with the third charging interface 222c of the charging device 20, while the second interface 228b is configured to interface with the charging interface of the gardening robot tool 60. The energy storage charging device 20 can output electrical energy through the third charging interface 222c and transmit the electrical energy to the gardening robot tool 60 via the adapter 228 for charging. The first charging module 223 has an input connected to the battery module 210 and outputs connected to the first, second, and third charging interfaces 222a, 222b, 222c. The first charging module 223 is configured to convert the DC power stored in the battery module 210 to charge the battery pack 10 or for use in other devices. Typically, the first charging module 223 performs voltage conversion, converting the voltage received at the input to an output voltage compatible with the battery pack 10. The input end of the second charging module 224 is connected to the AC input interface 225 for connecting to the mains power, and the output end is connected to the battery module 210. The second charging module 224 is used to convert the AC power provided by the mains power into DC power to charge the battery module 210. The energy storage charging device 20 provided in this embodiment can charge the battery pack 10 using the DC power of the battery module 210, and can also charge the battery module 210 using an AC power source, thereby meeting user needs in different scenarios.

[0194] 9 , when the charging device is configured as a battery pack charger 50, the device components include a battery pack 10 and a battery pack charger 50. The battery pack charger 50 is capable of electrically connecting to and charging the battery pack 10, and the battery pack 10 is capable of communicating with the battery pack charger 50. The battery pack charger 50 is configured with a first charger wireless communication module 502 (i.e., the device wireless communication module of the aforementioned charging device).

[0195] In the first battery pack communication mode, the battery pack data is directly transmitted to the user terminal 30 through the battery pack wireless communication module 101; in the second battery pack communication mode, the battery pack charger 50 receives the battery pack data and transmits it to the user terminal through the first charger wireless communication module 502.

[0196] Furthermore, the battery pack charger 50 is also equipped with a charger wired communication module 501 (i.e., the device wired communication module of the aforementioned charging device). When the battery pack wired communication module 102 of the battery pack 10 is connected to the charger wired communication module 501 of the battery pack charger 50, the battery pack 10 and the battery pack charger 50 can exchange data via wired communication.

[0197] The battery pack charger 50 is typically used to connect to the battery pack 10 to charge the battery pack 10. The battery pack charger 50 includes a charger housing 510, a battery pack charging interface 520 disposed on the charger housing 510, and a charging circuit disposed within the charger housing 510. The charging circuit is electrically connected to the battery pack charging interface 520. The charging circuit is used to connect to an external AC power source and convert the input AC power into DC power and output it through the battery pack charging interface 520 to charge the battery pack 10 connected to the battery pack charging interface 520.

[0198] As an example, the first charger wireless communication module 502 can be a 3G module, a 4G module, a 5G module, a LoRa module, a SigmaFox module, or a NB-IoT module. The battery pack wireless communication module 101 can be a Bluetooth module, a Zigbee module, a sub-1G module, or an RF433 module. Preferably, in this embodiment, the first charger wireless communication module 502 uses a 4G module, and the battery pack wireless communication module 101 uses a Bluetooth module.

[0199] It can be understood that in the above embodiment, the user terminal 30 is used to interact with the device in the device assembly, the battery pack 10 and other devices in the embodiments described later, and provide a human-computer interaction interface to the user. The human-computer interaction includes displaying the status information of the device, the battery pack 10 and other devices in the embodiments described later to the user and / or receiving control instructions for the device, the battery pack 10 and other devices in the embodiments described later input by the user.

[0200] Furthermore, as shown in FIG1 , the user terminal 30 includes an interactive terminal 301 and a cloud server 302 .

[0201] The interactive terminal 301 can be configured as a smartphone, a tablet computer, a laptop computer, or other smart wearable device, such as a smartwatch or smart bracelet. Preferably, the interactive terminal 301 is configured as a smartphone with a touch screen for human-computer interaction. Specific options for the interactive terminal 301 are not listed here; as long as they do not exceed the core concept of the present invention, they are also within the scope of protection of the present invention.

[0202] In this embodiment, the interactive terminal 301 is configured with a first terminal wireless communication module 301a capable of short-range communication and a second terminal wireless communication module 301b capable of long-range communication. As previously described, the battery pack 10 is configured with a battery pack wireless communication module 101 capable of short-range communication. The battery pack wireless communication module 101 is configured to match the first terminal wireless communication module 301a. The battery pack 10 can communicate with the interactive terminal 301 through the battery pack wireless communication module 101 and the first terminal wireless communication module 301a, thereby enabling data exchange between the battery pack 10 and the interactive terminal 301. Preferably, the first terminal wireless communication module 301a is a Bluetooth module that matches the battery pack wireless communication module, and the second terminal wireless communication module 301b can be configured as a 4G module, a 5G module, a WiFi module, etc.

[0203] The cloud server 302 can select a server with functions such as data storage, information interaction and device control according to actual application requirements, such as a cloud server based on the AWS cloud service platform. The specific implementation methods of the cloud server 302 are no longer listed here one by one. Under the premise of not exceeding the core idea of ​​the present invention, they also fall within the scope of protection of the present invention.

[0204] In this embodiment, the cloud server 302 is configured to be connected to the Internet via a network communication module. The device can be connected to the Internet via a device wireless communication module that enables long-distance communication. The Internet enables communication between the device and the cloud server 302, thereby enabling data exchange between the device and the cloud server 302. Specifically, the network communication module can be a wired communication form such as fiber optic communication, or other wireless communication forms such as 4G, 5G, and WiFi, which are not limited here. Preferably, the cloud server 302 is connected to the Internet via fiber optic communication.

[0205] Since the interactive terminal 301 can also connect to the Internet via the second terminal wireless communication module 301b capable of long-distance communication, it can then interact with the cloud server 302 via the Internet and share the corresponding data. Furthermore, since the cloud server 302 generally has a large data storage capacity, the interactive terminal 301 can also upload the interactive data it receives to the cloud server 302 to achieve data backup and ensure data storage security.

[0206] It is understandable that the battery pack 10 communicates with the user terminal 30 through different communication modes in different scenarios.

[0207] For the first battery pack communication mode, taking the interactive terminal 301 as a smartphone as an example, in a work scenario, equipment operators of a gardening team often work in a work area with handheld power tools. When the equipment operator carries the interactive terminal 301 with them, the interactive terminal 301 of the equipment operator has established an association with the battery pack 10 connected to their handheld power tool, and the Bluetooth function of the interactive terminal 301 of the equipment operator is turned on, the interactive terminal 301 is within the communication range of the second wireless communication module 101 of the battery pack 10. The battery pack 10 can establish communication with the user terminal 30 through the battery pack wireless communication module 101. At this time, the battery pack 10 can communicate with the user terminal 30 through the first battery pack communication mode. The data of the battery pack 10 is directly transmitted to the user terminal 30 through the first battery pack communication mode. In addition, the battery pack 10 may also be used in a scenario where it is connected to a battery pack charger 50 for charging, the battery pack 10 is in a working area, and the interaction terminal 301 of the device operator is still within the communication range of the battery pack wireless communication module 101; or the battery pack 10 may be used in a scenario where it is not connected to any power tool 40 or battery pack charger 50, the battery pack 10 is in a working area, and the interaction terminal 301 of the device operator is still within the communication range of the battery pack wireless communication module 101, at which point the battery pack 10 transmits the internally stored data of the battery pack 10 to the user terminal 30 via the first battery pack communication mode; or other application scenarios in which the battery pack 10 is actually used, which are not listed here. Among them, the communication range of the battery pack wireless communication module 101 is the communication range of the Bluetooth module.

[0208] For the second battery pack communication mode, when the battery pack 10 is low on power and needs to be charged, the battery pack 10 is separated from the power tool 40 and connected to the charging device for charging. At this time, the battery pack 10 and the charging device can establish communication in a wired communication manner. Since the charging device can establish communication with the user terminal 30 through the device wireless communication module, the battery pack 10 can communicate with the user terminal 30 through the second battery pack communication mode. The data of the battery pack 10 is first transmitted to the charging device through a wired communication manner, and then transmitted to the user terminal 30 through the device wireless communication module of the charging device; it can also be other application scenarios of the battery pack 10 during actual use, which are not listed here one by one.

[0209] In addition, it is understood that the data transmission between the battery pack 10 and the user terminal 30 is bidirectional, including both data transmission from the battery pack 10 to the user terminal 30 and data transmission from the user terminal 30 to the battery pack 10. The data transmission between the charging device and the user terminal 30 is also bidirectional, including both data transmission from the charging device to the user terminal 30 and data transmission from the user terminal 30 to the charging device.

[0210] As an example, the battery pack 10 transmits battery pack operating status data to the user terminal 30 via the battery pack wireless communication module 101, and receives battery pack control instruction data sent by the user terminal 30. Alternatively, the charging device receives the battery pack operating status data and transmits it to the user terminal 30 via the device wireless communication module, and the charging device receives the battery pack control instruction data sent by the user terminal 30 via the device wireless communication module and transmits it to the battery pack 10. The charging device transmits the charging device operating status data to the user terminal 30 via the device wireless communication module, and receives the charging device control instruction data sent by the user terminal 30.

[0211] In the device components of the present application, the battery pack 10 is configured with a first battery pack communication mode and a second battery pack communication mode. The first battery pack communication mode realizes short-distance communication of the battery pack, and the second battery pack communication mode realizes long-distance communication of the battery pack with the help of the device wireless communication module of the device. Compared with the existing technology, two data interaction modes are provided between the battery pack 10 and the user terminal 30. The two data interaction modes can realize data interaction between the battery pack 10 and the user terminal 30 in different scenarios, which can improve the reliability of data interaction between the battery pack and the user terminal, thereby ensuring that the user can effectively monitor and manage the battery pack 10.

[0212] Furthermore, due to the short-range communication mode, when the user carries the interactive terminal 301 away from the battery pack 10 and exceeds the communication distance of the battery pack wireless communication module 101, the battery pack 10 cannot establish communication with the interactive terminal 301. At this time, the battery pack is in an offline state. In this case, since the battery pack 10 itself has a certain amount of storage space, the battery pack will store the working status data when it is offline. In actual applications, the battery pack 10 can store its own data. At the same time, it can also store data of the power tool 40 or battery pack charger 50 connected to the battery pack 10. However, since the storage space of the battery pack 10 itself is limited, when the battery pack is offline for a long time, the data cannot be stored or the stored data is lost due to insufficient storage space, which affects the user's monitoring and management of the battery pack. In this case, taking the device configuration as a charging device as an example, when the battery pack 10 is connected to the charging device for charging, the battery pack 10 and the charging device establish communication via wired communication. The battery pack can then transmit data stored offline to the charging device, which is then further transmitted to the cloud server 302 via the device wireless communication module of the charging device. This allows the data from the battery pack 10 to be transmitted to the cloud server 302 via the charging device. Of course, data from the cloud server 302 can also be transmitted to the battery pack 10 via the reverse transmission method. Furthermore, depending on the actual situation, if the data received by the cloud server 302 needs to be displayed on the interactive terminal 301, or if the data received by the interactive terminal 301 needs to be stored or processed on the cloud server 302, the cloud server 302 and the interactive terminal 301 may further exchange data. Of course, when the battery pack 10 and the charging device are connected via wired communication, the battery pack 10 can also transmit real-time data from the battery pack 10 to the charging device, and the charging device can further transmit the real-time data from the battery pack 10 to the cloud server 302 via the device wireless communication module.

[0213] In the above embodiment, the data of the battery pack 10 includes at least the operating status data of the battery pack, which includes one or more of the current status information of the battery pack 10, charge and discharge parameter information, and battery pack fault information. The current status information of the battery pack includes the charge and discharge status information of the battery pack and the number of charge and discharge cycles. The charge and discharge status information is used to indicate whether the battery pack 10 is in a charging state, a discharging state, or a non-charge and discharge state. The charge and discharge parameter information includes one or more of the cell voltage, charge and discharge current, cell temperature, SOC, SOP, SOH, elapsed charge time, and remaining charge time. The battery pack fault information includes communication failure, temperature sensor abnormality, voltage abnormality, temperature abnormality, charge and discharge overcurrent fault, battery pack hardware failure, and mismatch between the battery pack and the tool.

[0214] In the above embodiment, the data of the energy storage charging device 20 at least includes the operating status data of the energy storage charging device, and the operating status data of the energy storage charging device includes one or more of the current status information of the charging device, charging and discharging parameter information, and charging device fault information. The current status information of the charging device includes the charging and discharging status information of the charging device and the number of charging and discharging cycles. The charging and discharging status information is used to indicate whether the energy storage charging device 20 is in a charging state, a discharging state, or a non-charging and discharging state. The charging and discharging parameter information includes one or more of voltage, current, temperature, SOC, SOP, SOH, charging time, and remaining charging time. The charging device fault information includes communication anomalies, relay failures, temperature anomalies, device charging system failures, charging interface current anomalies, built-in pack charging anomalies, and charging interface battery pack charging anomalies.

[0215] In the above embodiment, the data of the battery pack charger includes at least the working status data of the battery pack charger, and the working status data of the battery pack charger includes one or more of the charger operating parameters of the battery pack charger, the charging power in the charging state, the remaining charging time, the cumulative charging time and the number of charging times, the charging records, and the charger fault information.

[0216] Compared to existing technologies, the battery pack 10 is equipped with two communication modes. This not only enables communication between the battery pack and the user terminal 30 in different scenarios, improving the reliability of data exchange between the two terminals and ensuring effective user monitoring and management of the battery pack 10 while maintaining low costs, but also prevents data loss in the battery pack 10 due to limited internal storage space when the battery pack is offline for extended periods. Furthermore, the communication mode in which battery pack data is transmitted to the user terminal via the device provides a communication link that can transmit battery pack 10 data to the user terminal 30 without being restricted by the use of the interactive terminal 301.

[0217] Furthermore, the battery pack data is divided into real-time data and historical data stored in the battery pack based on the real-time nature of the data. The battery pack data received by the device includes real-time data and historical data stored in the battery pack. It should be noted that real-time data refers to the current data after the battery pack is connected to the device, while historical data stored in the battery pack refers to data stored in the battery pack before the battery pack is connected to the device.

[0218] As previously described, the battery pack 10 communicates with the charging device via wired communication. The charging device is equipped with a device wired communication module, and the battery pack 10 is equipped with a battery pack wired communication module 102. Furthermore, the battery pack includes a first battery pack terminal, and the device includes a first device terminal. The first battery pack terminal and the first device terminal are electrically connected to form a data transmission path. Both real-time data from the battery pack and historical data stored in the battery pack are transmitted to the device via this data transmission path.

[0219] In this embodiment, the battery pack 10 includes a charging interface for connecting to a charging interface of a charging device. The battery pack charging interface includes a positive terminal, a negative terminal, an analog signal communication terminal, and a digital signal communication terminal. The charging interface of the charging device includes a positive terminal, a negative terminal, an analog signal communication terminal, and a digital signal communication terminal that match the charging interface of the battery pack.

[0220] As an example, the battery pack's charging interface includes a digital signal communication terminal, namely, the aforementioned first battery pack terminal. The charging device's charging interface also includes a digital signal communication terminal, namely, the aforementioned first charging device terminal. The first battery pack terminal and the first charging device terminal are electrically connected to form a data transmission path, and both the real-time data of the battery pack 10 and the historical data stored in the battery pack 10 are transmitted to the charging device via this data transmission path.

[0221] Specifically, the first battery pack terminal can be configured as a serial port terminal, and the first charging device terminal can be configured as a serial port terminal. The first battery pack terminal is used to electrically connect with the first charging device terminal to form a serial port signal transmission path. The real-time data of the battery pack and the historical data stored in the battery pack 10 are transmitted to the charging device through this serial port signal transmission path.

[0222] Alternatively, the first battery pack terminal and the first charging device terminal are both configured as CAN terminals, the CAN terminals of the battery pack 10 include a first CAN terminal and a second CAN terminal, and the CAN terminals of the charging device include a third CAN terminal and a fourth CAN terminal. The first CAN terminal is electrically connected to the third CAN terminal, and the second CAN terminal is electrically connected to the fourth CAN terminal to form a differential signal transmission path. The real-time data of the battery pack and the historical data stored in the battery pack 10 are both transmitted to the charging device through this differential signal transmission path.

[0223] As another example, the charging interface of the battery pack includes two digital signal communication terminals, and the charging interface of the charging device also includes two digital signal communication terminals.

[0224] Specifically, the two digital signal communication terminals of the battery pack 10 are a serial port terminal and a pair of CAN terminals, respectively, while the two communication terminals of the charging device are a serial port terminal and a pair of CAN terminals. When the battery pack 10 and the energy storage charging device 20 are connected, the serial port terminal of the battery pack 10 and the serial port terminal of the charging device are electrically connected to form a serial port signal transmission path, i.e., a serial port signal transmission path. The pair of CAN terminals of the battery pack 10 and the pair of CAN terminals of the charging device are electrically connected to form a differential signal transmission path. The battery pack 10 and the charging device select either the serial port signal transmission path or the differential signal transmission path to transmit the battery pack's real-time data and historical data stored within the battery pack 10. Furthermore, the differential signal transmission path is preferentially selected to transmit the battery pack's real-time data and historical data stored within the battery pack 10.

[0225] In the above-described embodiment, the charging device can be configured as an energy storage charging device 20 or as a battery pack charger 50. Taking the energy storage charging device 20 as an example, as shown in Figure 10, in this embodiment, the positive terminal, negative terminal, analog signal communication terminal, and digital signal communication terminal of the charging interface of the energy storage charging device 20 are configured in the form of electrodes. Specifically, the positive terminal is configured as a positive electrode electrode 201, the negative terminal is configured as a negative electrode electrode 202, the analog signal communication terminal is configured as an analog signal communication electrode 203, and the communication terminals are configured as a first digital signal communication electrode 204 and a second digital signal communication electrode 205. The energy storage charging device 20 has two digital communication modes, allowing it to communicate with two different types of battery packs 10. In this embodiment, the communication type of the first digital signal communication electrode 204 is serial communication, corresponding to the serial port terminal of the energy storage charging device 20, and the communication type of the second digital signal communication electrode 205 is differential communication. Specifically, the differential communication can be CAN (Controller Area Network) communication. The second digital signal communication electrode 205 has two plugs, 205a and 205b, corresponding to a pair of CAN terminals of the energy storage charging device 20. The plugs 205a and 205b are independent and insulated from each other. When the energy storage charging device 20 communicates with the battery pack 10, digital communication with the battery pack 10 is preferentially performed through the second digital communication electrode 205. When the second digital signal communication fails, the first digital signal communication electrode 204 is used to digitally communicate with the second energy storage module. The energy storage charging device 20 can establish communication with battery packs 10 with a variety of different interface structures, such as battery packs 10 that only include a serial communication module, battery packs 10 that include both a serial communication module and a CAN communication module, and battery packs 10 that only include a CAN communication module. This has a wider range of applications and can improve the compatibility of the energy storage charging device 20.

[0226] Accordingly, as shown in FIG11 , the positive terminal, negative terminal, analog signal communication terminal, and digital signal communication terminal of the charging interface of the battery pack provided in this embodiment are configured as contacts. Specifically, the positive terminal is configured as a positive contact 110, the negative terminal is configured as a negative contact 120, the analog signal communication terminal is configured as an analog signal communication contact 130, and the digital signal communication terminal is configured as a first digital signal communication contact 140 and a second digital signal communication contact 150. In this embodiment, the communication type of the first digital signal communication contact 304 is serial communication, corresponding to the serial port terminal of the battery pack 10, and the communication type of the second digital signal communication contact 150 is differential communication. Specifically, the differential communication may be CAN communication. The second digital signal communication contact 150 includes two independent contacts, namely, contact 150a and contact 150b, corresponding to a pair of CAN terminals of the battery pack 10. Contacts 150a and 150b are disposed in the same terminal slot, with an insulator disposed between them. When the battery pack 10 is directly inserted into the charging port of the charging device 20, the positive pole piece 201, the negative pole piece 202, the analog signal communication pole piece 203, the first digital signal communication pole piece 204 and the second digital signal communication pole piece 205 are respectively connected to the positive contact 110, the negative contact 120, the analog signal communication contact 130, the first digital signal communication contact 140 and the second digital signal communication contact 150.

[0227] Specifically, the charging interface of the energy storage charging device 20 is provided with a charging electrode, and the charging interface of the battery pack 10 is provided with an interface slot, each interface slot is provided with a charging contact. When the battery pack 10 is plugged into the energy storage charging device 20, the charging electrode at the end of the energy storage charging device 20 can be inserted into the interface slot on the side of the battery pack 10 and electrically connected to the charging contacts one by one.

[0228] Furthermore, the real-time data of the battery pack received by the charging device may include the charge and discharge status information of the battery pack 10, the number of charge and discharge cycles, the charge request current, the cell voltage, the cell temperature, the SOC, the SOP, the SOH, the charged time, the remaining charge time, the real-time fault information, etc. It should be noted that the charge request current, i.e., the charge and discharge current data of the battery pack 10 mentioned above, is the charge request current when the battery pack 10 is in the charging state, and the discharge current when the battery pack 10 is in the discharging state. That is to say, when the battery pack 10 is connected to the charging device for charging, the data is the charge request current. The historical data stored in the battery pack 10 may include historical faults of the battery pack 10, historical faults of the power tool stored in the battery pack 10, historical faults of the battery pack charger stored in the battery pack 10, the power tool usage record stored in the battery pack 10, the power tool industrial control data stored in the battery pack 10, and the charging record of the battery pack charger stored in the battery pack 10.

[0229] The above-mentioned real-time data of the battery pack and the historical data stored in the battery pack 10 are both transmitted to the device via a data transmission path. Furthermore, during the process of the battery pack 10 being connected to the device and transmitting power, the real-time data of the battery pack 10 and the historical data stored in the battery pack 10 are transmitted at different time periods. Taking the device as a charging device as an example, during the process of the battery pack 10 being connected to the charging device 20 and charging, the real-time data of the battery pack and the historical data stored in the battery pack 10 are transmitted at different time periods. It can be understood that by transmitting the real-time data of the battery pack and the historical data stored in the battery pack 10 via a data transmission path, the number of communication terminals set between the battery pack 10 and the device can be reduced, the terminal structure can be simplified, and the overall cost can be reduced. Furthermore, by transmitting the real-time data of the battery pack and the historical data stored in the battery pack 10 at different time periods during the process of the battery pack 10 being connected to the device and transmitting power, the idle time of the data transmission path can be fully utilized to transmit data, thereby improving data transmission efficiency.

[0230] 12 , in this embodiment, the communication method between the battery pack 10 and the charging device includes:

[0231] Step S121, the charging device detects the analog signal of the analog signal communication electrode of the charging interface to identify whether the charging interface is connected to the battery pack 10;

[0232] Step S122 , when the charging device recognizes that the charging interface is connected to the battery pack 10 , it establishes communication with the battery pack 10 and assigns an address to the battery pack 10 ;

[0233] In step S123 , the battery pack 10 and the charging device perform data exchange according to a preset data transmission method.

[0234] Furthermore, in step S121, when it is identified that the voltage value of the analog signal of the analog signal communication electrode is within the set voltage range and lasts for more than the set time, it is judged that the charging interface of the charging device is connected to the battery pack 10; preferably, when the voltage range is 0.98-2.2V and the duration is more than 500ms, it is judged that the charging interface of the charging device is connected to the battery pack 10.

[0235] Furthermore, in step S122 , the charging device and the battery pack 10 perform digital communication via the CAN terminal first. When the CAN communication fails, digital communication is performed via the serial port terminal.

[0236] Furthermore, in step S123, the preset data transmission method may include the battery pack 10 proactively transmitting various types of real-time data of the battery pack 10 to the charging device at a set period, while the battery pack 10's historical data is transmitted to the charging device during idle periods of the data transmission path in response to query commands from the charging device. Specifically, as shown in FIG13 , each type of real-time data of the battery pack 10 is assigned a data reporting period. For example, the data reporting period for charging request current data may be 500ms. The battery pack 10 periodically reports the real-time data. After receiving the real-time data from the battery pack 10, the charging device sends a confirmation message confirming successful reporting to the battery pack 10. The battery pack 10 then marks the real-time data reporting status as successful, thus completing the transmission of the real-time data of the battery pack 10. As shown in Figure 14, when the data transmission path is idle, the charging device traverses the battery pack storage ID and sends a command to read the historical data of the battery pack 10 to the battery pack 10. The battery pack 10 receives and responds to the command, reads the historical data according to the storage ID, and transmits the historical data to the charging device. After receiving the historical data, the charging device sends a confirmation report success message to the battery pack 10. The battery pack 10 marks the historical data reporting success status, and the transmission of the historical data of the battery pack 10 is completed.

[0237] Furthermore, in order to avoid data transmission errors, when the battery pack 10 exchanges data with the charging device, one data transmission is completed before the next one is transmitted.

[0238] 2 and 8 , the battery pack 10 can be connected to and powered by a power tool 40, and the power tool 40 can communicate with the battery pack 10. The battery pack 10 can receive data from the power tool 40 and transmit it to the user terminal 30 via the battery pack wireless communication module 101.

[0239] As an example, the power tool 40 and the battery pack 10 communicate via wired communication when they are paired. Specifically, the power tool 40 and the battery pack 10 are provided with matching wired communication modules. When the power tool 40 and the battery pack 10 are paired, the two exchange data via wired communication. The battery pack 10 is configured with a battery pack wired communication module 102, and the power tool 40 is configured with a tool wired communication module 401. The battery pack 10 receives the power tool data through the battery pack wired communication module 102 and the tool wired communication module 401 and transmits it to the user terminal 30 through the battery pack wireless communication module 101. Among them, the wired communication module described in this embodiment can be any one of a serial communication module and a CAN communication module. Of course, it can also be other forms of wired transmission modules, which also fall within the scope of protection of the present invention without exceeding the scope of the core idea of ​​the present invention. Preferably, the battery pack wired communication module 102 and the tool wired communication module 401 adopt a serial communication module.

[0240] When the power tool 40 is connected to the battery pack 10, the battery pack 10 provides power to the power tool 40, meeting the power requirements of the power tool 40 during operation. In practical applications, the power tool 40 can be configured as one or more of a lawn mower, a brush cutter, an edger, pruning shears, a high-pressure washer, a hair dryer, a chain saw, a push mower, a multi-tasking tool, and a sprayer. Of course, other power tools 40 requiring independent power modules can also be configured. These are not listed here, but fall within the scope of the present invention without departing from the core concept of the present invention.

[0241] In this embodiment, the battery pack 10 can receive data from the power tool 40 and transmit it to the user terminal 30 via the battery pack wireless communication module 101. The power tool 40 can exchange data with the user terminal 30 without the need for a wireless communication module, effectively reducing production and / or usage costs.

[0242] Furthermore, two communication modes are also configured between the power tool 401 and the user terminal 30. The first is that the data of the power tool is transmitted to the battery pack 10 through wired communication, and then transmitted to the communication link of the user terminal 30 through the battery pack wireless communication module 101 of the battery pack 10; the second is that the data of the power tool 40 is transmitted to the battery pack 10 through wired communication, and then transmitted to the charging device by the battery pack 10 through wired communication, and then transmitted to the communication link of the user terminal 30 through the device wireless communication module of the charging device.

[0243] In this embodiment, the charging device can be either an energy storage charging device 20 or a battery pack charger 50. FIG2 illustrates the energy storage charging device 20 as an example, but the present invention is not limited thereto. The specific implementations of the energy storage charging device 20 and the battery pack charger 50 can be found in the previous embodiments and will not be further elaborated here.

[0244] It is understandable that the power tool 40 communicates with the user terminal 30 through different communication links in different scenarios.

[0245] 2 , taking the case where the power tool 40 transmits data to the user terminal 30 and the interactive terminal 301 is a smart phone as an example:

[0246] In a work scenario, equipment operators of a gardening team often use handheld power tools in a work area. When the equipment operator carries an interactive terminal 301, the interactive terminal 301 is associated with the battery pack 10 connected to the handheld power tool, and the Bluetooth function of the interactive terminal 301 is enabled, the interactive terminal 301 is within the communication range of the battery pack wireless communication module 101 of the battery pack 10. The battery pack 10 can establish communication with the user terminal 30 through the battery pack wireless communication module 101. When the battery pack 10 is connected to the power tool 40 to provide power to the power tool 40, data from the power tool 40 can be transmitted to the battery pack 10 via wired communication, and then transmitted to the user terminal 30 via the battery pack wireless communication module 101 of the battery pack 10. That is, the battery pack 10 receives data from the power tool 40 and transmits it to the user terminal 30 in real time. Other application scenarios of the power tool 40 during actual use are also possible, and are not listed here.

[0247] Accordingly, when the device operator does not carry the interactive terminal 301, or the interactive terminal 301 is not associated with the battery pack 10 connected to the handheld power tool, or the Bluetooth function is not enabled on the interactive terminal 301, the distance between the interactive terminal 301 and the battery pack 10 exceeds the communication range of the battery pack wireless communication module 101. In this case, the battery pack 10 cannot establish communication with the user terminal 30 through the battery pack wireless communication module 101. When the battery pack 10 is connected to the power tool 40 to provide power to the power tool 40, since the battery pack 10 itself has a certain amount of storage space, the battery pack 10 can receive the data stored in the power tool 40. That is, the data of the power tool 40 can be transmitted to the battery pack 10 for storage via wired communication. Then, when the battery pack 10 establishes communication with the user terminal 30 again, the stored data of the power tool 40 can be sent to the user terminal 30. It can be understood that the aforementioned battery pack 10 establishing communication with the user terminal 30 again can be a scenario in which the battery pack 10 establishes communication with the user terminal 30 again through the battery pack wireless communication module 101; it can also be a scenario in which the battery pack 10 is separated from the power tool 40 and connected to the charging device for charging when the battery pack 10 is low on power and needs to be charged. At this time, the battery pack 10 and the charging device can establish communication in a wired communication manner. Since the charging device can establish communication with the user terminal 30 through the device wireless communication module, the data of the power tool 40 stored in the battery pack 10 can be transmitted to the charging device via wired communication, and then transmitted to the user terminal 30 through the device wireless communication module of the charging device; it can also be other application scenarios of the power tool 40 during actual use, which are not listed here one by one.

[0248] In addition, it can be understood that the data transmission between the power tool 40 and the user terminal 30 is bidirectional, including both the power tool 40 transmitting data to the user terminal 30 and the user terminal 30 transmitting data to the power tool 40 .

[0249] As an example, the power tool 40 transmits working status data to the user terminal 30 through the battery pack 10 , and receives power tool control instruction data sent by the user terminal 30 through the battery pack 10 .

[0250] Furthermore, the data of the power tool 40 includes one or more of the following: industrial control data of the power tool 40, remaining power in the working state, remaining tool usage time, number of on / off cycles, cumulative working time, tool usage records, and tool fault information. The tool fault information includes circuit faults, communication faults, current faults, voltage faults, temperature faults, etc.

[0251] Compared to existing technologies, the power tool 40 is equipped with two communication modes. This not only enables communication between the power tool 40 and the user terminal 30 in different scenarios, improving the reliability of data exchange between the power tool 40 and the user terminal 30, ensuring that the user can effectively monitor and manage the power tool 40, but also achieving low costs. Furthermore, it also prevents the loss of power tool data stored in the battery pack 10 due to the limited internal storage space of the battery pack 10 when the battery pack 10 is offline for a long time. Furthermore, the communication mode in which data from the power tool 40 is transmitted to the user terminal via the battery pack and charging device provides a communication link that can transmit data from the power tool 40 to the user terminal 30 without being restricted by the use of the interactive terminal 301.

[0252] 3 and 9 , the battery pack 10 can be connected to and charged by the battery pack charger 50, and the battery pack charger 50 can communicate with the battery pack 10. The battery pack 10 can receive data from the battery pack charger 50 and transmit it to the user terminal 30 via the battery pack wireless communication module 101.

[0253] As an example, the battery pack charger 50 and the battery pack 10 communicate through wired communication when they are matched. Specifically, the battery pack charger 50 and the battery pack 10 are provided with matching wired communication modules. When the battery pack charger 50 and the battery pack 10 are matched, the two exchange data through wired communication. The battery pack 10 is configured with a battery pack wired communication module 102, and the battery pack charger 50 is configured with a charger wired communication module 501. Among them, the wired communication module described in this embodiment can be any one of a serial communication module and a CAN communication module. Of course, it can also be other forms of wired transmission modules. If it does not exceed the scope of the core idea of ​​the present invention, it also falls within the scope of protection of the present invention. Preferably, the battery pack wired communication module 102 and the charger wired communication module 501 adopt a serial communication module or a CAN communication module.

[0254] The specific implementation of the battery pack charger 50 can refer to the aforementioned embodiment and will not be described again here.

[0255] In this embodiment, the battery pack 10 can receive data from the battery pack charger 50 and transmit it to the user terminal 30 via the battery pack wireless communication module 101. The battery pack charger 50 can exchange data with the user terminal 30 without the need for a wireless communication module, effectively reducing production and / or usage costs.

[0256] Furthermore, two communication modes are also configured between the battery pack charger 50 and the user terminal 30. The first is that the data of the battery pack charger 50 is transmitted to the battery pack 10 through wired communication, and then transmitted to the communication link of the user terminal 30 through the battery pack wireless communication module 101 of the battery pack 10; the second is that the data of the battery pack charger 50 is transmitted to the battery pack 10 through wired communication, and then transmitted to the device by the battery pack 10 through wired communication, and then transmitted to the communication link of the user terminal 30 through the first wireless communication module of the device.

[0257] In this embodiment, the charging device may be an energy storage type charging device 20. The specific implementation of the energy storage type charging device 20 may refer to the above embodiment and will not be described in detail here.

[0258] It is understandable that the battery pack charger 50 communicates with the user terminal 30 through different communication modes in different scenarios.

[0259] 3 , taking the case where the battery pack charger 50 transmits data to the user terminal 30 and the interactive terminal 301 is a smartphone as an example:

[0260] In a work scenario, the equipment operators of a gardening team often work within a work area. The battery pack 10, battery pack charger 50, etc. carried by the gardening team are all placed near the work area. When the equipment operator carries an interactive terminal 301, the interactive terminal 301 of the equipment operator has established an association with the battery pack 10, and the Bluetooth function of the interactive terminal 301 of the equipment operator is turned on, the interactive terminal 301 is within the communication range of the battery pack wireless communication module 101 of the battery pack 10. The battery pack 10 can establish communication with the user terminal 30 through the battery pack wireless communication module 101. When the battery pack 10 is connected to the battery pack charger 50 for charging, the data of the battery pack charger 50 can be transmitted to the battery pack 10 via wired communication, and then transmitted to the user terminal 30 via the battery pack wireless communication module 101 of the battery pack 10. That is, the battery pack 10 receives the data of the battery pack charger 50 and transmits it to the user terminal 30 in real time. Other application scenarios of the battery pack charger 50 in actual use can also be used, which are not listed here.

[0261] Accordingly, when the device operator does not carry the interactive terminal 301, or the interactive terminal 301 of the device operator is not associated with the battery pack 10, or the Bluetooth function of the interactive terminal 301 of the device operator is not enabled, the distance between the interactive terminal 301 and the battery pack 10 exceeds the communication range of the second wireless communication module 101. At this time, the battery pack 10 cannot establish communication with the user terminal 30 through the battery pack wireless communication module 101. When the battery pack 10 is connected to the battery pack charger 50 for charging, since the battery pack 10 itself has a certain amount of storage space, the battery pack 10 can receive the data stored in the battery pack charger 50. That is, the data of the battery pack charger 50 can be transmitted to the battery pack 10 for storage via wired communication. Then, when the battery pack 10 establishes communication with the user terminal 30 again, the stored data of the battery pack charger 50 is sent to the user terminal 30. It can be understood that the aforementioned battery pack 10 establishing communication with the user terminal 30 again can be a scenario in which the battery pack 10 establishes communication with the user terminal 30 again through the battery pack wireless communication module 101; it can also be a usage scenario in which the battery pack 10 is separated from the power tool 40 and connected to the charging device for charging when the battery pack 10 is low on power and needs to be charged. At this time, the battery pack 10 and the charging device can establish communication in a wired communication manner. Since the charging device can establish communication with the user terminal 30 through the device wireless communication module, the data of the battery pack charger 50 stored in the battery pack 10 can be transmitted to the charging device through wired communication, and then transmitted to the user terminal 30 through the device wireless communication module of the charging device; it can also be other application scenarios of the battery pack charger 50 during actual use, which are not listed here one by one.

[0262] In addition, it can be understood that the data transmission between the battery pack charger 50 and the user terminal 30 is bidirectional, including both the battery pack charger 50 transmitting data to the user terminal 30 and the user terminal 30 transmitting data to the battery pack charger 50 .

[0263] As an example, the battery pack charger 50 transmits operating status data to the user terminal 30 through the battery pack 10 , and receives battery pack charger control instruction data sent by the user terminal 30 through the battery pack 10 .

[0264] Furthermore, the data of the battery pack charger 50 includes one or more of the charger operating parameters of the battery pack charger 50, the charging power in the charging state, the remaining charging time, the cumulative charging time and the number of charging times, the charging records, and the charger fault information. The charger fault information includes communication failure, circuit abnormality, temperature abnormality, battery compartment abnormality, etc.

[0265] Compared to existing technologies, the battery pack charger 50 is configured with two communication modes. This not only enables communication between the battery pack charger 50 and the user terminal 30 in different scenarios, improving the reliability of data exchange between the battery pack charger 50 and the user terminal 30, ensuring that users can effectively monitor and manage the battery pack charger 50, but also achieving low costs. Furthermore, it also prevents the loss of battery pack charger data stored in the battery pack 10 due to the limited internal storage space of the battery pack 10 when the battery pack 10 is offline for an extended period of time. Furthermore, the communication mode in which data from the battery pack charger 50 is transmitted to the user terminal via the battery pack and the charging device provides a communication link that can transmit data from the battery pack charger 50 to the user terminal 30 without being restricted by the use of the interactive terminal 301.

[0266] In summary, by configuring the device with a wireless communication module capable of long-distance communication, configuring the battery pack 10 with a wireless communication module capable of short-distance communication, and rationally configuring the communication methods between the battery pack, the device, and the user terminal, the device assembly effectively improves the reliability of communication between the battery pack, the device, and the user terminal, enabling users to effectively monitor and manage the battery pack and device. Furthermore, by efficiently utilizing the communication modules, low costs can be achieved. Furthermore, in addition to establishing reliable communication between the battery pack 10, the device, and the user terminal 30, data from the power tool 40 or battery charger 50 connected to the battery pack 10 can also be transferred. Based on this communication method, at least data from the battery pack 10, the device, the power tool 40, and the battery charger 50 can be displayed on the user terminal 30, and the user terminal 30 can control the functions of the battery pack 10, the device, the power tool 40, and the battery charger 50. This facilitates comprehensive monitoring and management of the battery pack 10, the device, the power tool 40, and the battery charger 50 by the user terminal 30. For example, by monitoring fault information during charging, discharging, or use of the battery pack 10, device, power tool 40, or battery pack charger 50 and reporting it to the user terminal 30, the user can immediately be informed of the fault status and promptly troubleshoot the fault to avoid affecting the normal use of the battery pack 10, device, power tool 40, or battery pack charger 50. Specifically, the fault information is transmitted in the form of a code, with different codes corresponding to different faults.

[0267] In other embodiments, the device assembly of the present application can also be configured as a power tool 40, with the battery pack 10 electrically connected to the power tool 40 and providing the power required for its operation. In this embodiment, the power tool 40 is equipped with the aforementioned device wireless communication module, and the battery pack 10 is equipped with a battery pack wireless communication module 101, enabling the battery pack 10 to communicate with the power tool 40 via wired communication. In the first battery pack communication mode, battery pack data is directly transmitted to the user terminal 30 via the battery pack wireless communication module 101; in the second battery pack communication mode, the power tool 40 receives the battery pack data and transmits it to the user terminal 30 via the device wireless communication module. The specific communication methods among the power tool 40, battery pack 10, and user terminal 30, as well as between them, can be referred to in the previous embodiments and will not be elaborated here.

[0268] The present application also provides a device system, which includes a first device, a battery pack and a central device provided with a first wireless communication module. The battery pack can be connected to the first device and provide power for the operation of the first device, and the battery pack can communicate with the first device. The central device and the first device are configured as devices that perform different work tasks; the central device can be electrically connected to the battery pack and transmit power, and the battery pack can communicate with the central device.

[0269] Both the data from the first device and the data from the battery pack can be transmitted to the user terminal via the first wireless communication module of the hub device. When the battery pack is connected to the first device, the battery pack receives and stores the data from the first device. When the battery pack is in communication with the hub device, the hub device receives the data from the battery pack and the data from the first device stored in the battery pack and transmits it to the user terminal via the first wireless communication module.

[0270] Wherein, the first device is configured as an electric tool.

[0271] It is understandable that the central device can be configured as a charging device that can be electrically connected to the battery pack and charge the battery pack, or it can be configured as an inverter or other device that can be electrically connected to the battery pack and provided with power by the battery pack.

[0272] In the device system of the present application, in addition to the central device provided with the first wireless communication module, the device system further includes a first type of device capable of communicating directly with the central device via wired communication, a second type of device capable of communicating with the first type of device via wired communication, and a third type of device capable of communicating with the central device via wireless communication. Of course, the device system may selectively include one or more of the first type of device, the second type of device, and the third type of device.

The data of the third type of device can be transmitted to the central device through the wireless communication module and the second wireless communication module of the third type of device, and transmitted to the user terminal through the first wireless communication module of the central device.

[0274] The power tool 40 may be one or more of a lawn mower, a brush cutter, an edge trimmer, a pruning shear, a high-pressure washer, a hair dryer, a chain saw, a push mower, a multi-tasking tool, and a sprayer. Of course, other power tools that require independent power modules may also be used, which are not listed here one by one.

[0275] The battery pack 10 can at least be used as a power source for the power tool 40 . In the application scenario shown in FIG8 , when the battery pack 10 is connected to the power tool 40 , the battery pack 10 can provide electrical energy to the connected power tool 40 .

[0276] 15 , an embodiment of the present application provides a device system, which includes a power tool, a battery pack, and a hub device equipped with a first wireless communication module. The hub device is configured as a charging device (i.e., the device system includes a peripheral device system and an energy system, wherein the peripheral device system includes a power tool, and the energy system includes a battery pack and a charging device). The battery pack can be connected to the power tool and power the power tool, and the battery pack can communicate with the power tool; the charging device can be electrically connected to the battery pack and charge the battery pack, and the battery pack can communicate with the charging device. Furthermore, the battery pack 10 communicates with the power tool 40 via wired communication to receive data from the power tool 40, and the charging device communicates with the battery pack 10 via wired communication to receive data from the battery pack 10.

[0277] Specifically, the battery pack 10 and the power tool 40 are provided with matching wired communication modules.

If it does not exceed the scope of the core idea of ​​the present invention, it also falls within the scope of protection of the present invention. Preferably, the wired communication module between the charging device and the battery pack 10 adopts a serial communication module or a CAN communication module.

[0279] Both power tool data and battery pack data can be transmitted to the user terminal 30 via the charging device's first wireless communication module. When the battery pack 10 is connected to the power tool 40, the battery pack 10 receives and stores the power tool 40 data.

Preferably, in this embodiment, the first wireless communication module adopts a 4G module.

[0281] In the above embodiment, the charging device can be configured as an energy storage charging device 20, or as a battery pack charger 50.

[0284] Furthermore, the energy storage charging device 20 is also equipped with a charging device wired communication module 202 (i.e., the device wired communication module of the aforementioned charging device). When the battery pack wired communication module 102 of the battery pack 10 is connected to the charging device wired communication module 202 of the energy storage charging device 20, the battery pack 10 and the energy storage charging device 20 can exchange data via wired communication.

For example, the battery pack 10 can be a handheld battery pack 10a, a backpack battery pack 10b, or other forms. It can be understood that the energy storage charging device 20, by providing the battery module 210, makes the charging process of the battery pack 10 no longer dependent on the AC power supply, thereby meeting the electricity needs of the garden team during outdoor work.

The battery pack charger 50 is provided with a first charger wireless communication module 502 (i.e., the first wireless communication module of the charging device described above).

[0288] Both the power tool data and the battery pack data can be transmitted to the user terminal 30 via the first charger wireless communication module 502 of the battery pack charger 50. When the battery pack 10 is connected to the power tool 40, the battery pack 10 receives and stores the data from the power tool 40. When the battery pack 10 is communicatively connected to the energy storage charging device 20, the battery pack charger 50 receives the battery pack data and the power tool data stored in the battery pack 10 and transmits them to the user terminal 30 via the first charger wireless communication module 502.

[0289] Furthermore, the battery pack charger 50 is also equipped with a charger wired communication module 501 (i.e., the device wired communication module of the aforementioned charging device). When the battery pack wired communication module 102 of the battery pack 10 is connected to the charger wired communication module 501 of the battery pack charger 50, the battery pack 10 and the battery pack charger 50 can exchange data via wired communication.

[0290] Preferably, in this embodiment, the first charger wireless communication module 502 is configured as a 4G module, and the charger wired communication module 501 and the battery pack wired communication module 102 use a serial communication module and / or a CAN communication module.

[0291] The battery pack charger 50 is typically used to connect to the battery pack 10 to charge the battery pack 10. The battery pack charger 50 includes a charger housing 510, a battery pack charging interface 520 disposed on the charger housing 510, and a charging circuit disposed within the charger housing 510. The charging circuit is electrically connected to the battery pack charging interface 520. The charging circuit is used to connect to an external AC power source and convert the input AC power into DC power and output it through the battery pack charging interface 520 to charge the battery pack 10 connected to the battery pack charging interface 520.

[0292] It will be understood that in the above-described embodiments, the user terminal 30 is used to exchange data with the power tool 40, battery pack 10, hub device, and other devices in the device system described below, and to provide a human-computer interaction interface to the user.

The specific implementation of the user terminal 30 can be found in the aforementioned device component embodiments and will not be further described here.

[0293] The specific application scenarios of this embodiment are as follows: When the battery pack 10 is connected to the power tool 40, it provides the power required for the power tool 40 to operate. When the battery pack 10 is unable to establish communication with the user terminal 30, the battery pack 10 receives and stores data from the power tool 40 via wired communication, while also storing its own data. When the battery pack 10 is separated from the power tool 40 and connected to a charging device for charging, the charging device receives the power tool 40 data and its own data stored in the battery pack 10 via wired communication and transmits them to the user terminal 30 via the first wireless communication module. This enables offline transmission of data from the power tool 40 and the battery pack 10. Neither the battery pack 10 nor the power tool 40 requires a wireless communication module; the charging device's first wireless communication module can transmit data from the power tool 40 and the battery pack 10 to the user terminal 30, effectively reducing communication costs. In addition, it should be noted that the battery pack 10 cannot establish communication with the user terminal 30. This may be because the battery 10 does not have a communication module that can communicate with the user terminal 30, or it may be that the battery pack 10 has a communication module that can communicate with the user terminal 30, but the distance between the battery pack 10 and the user terminal 30 exceeds the communication distance of the communication module, and therefore communication cannot be established.

[0294] Furthermore, it is understood that data transmission between the battery pack 10, the power tool 40, and the user terminal 30 is bidirectional, including both data transmission from the battery pack 10 and the power tool 40 to the user terminal 30, and data transmission from the user terminal 30 to the battery pack 10 and the power tool 40, such as control instructions for the battery pack 10 and the power tool 40. The operating status data of the charging device itself can also be transmitted to the user terminal 30 via the first wireless communication module, and data transmission between the charging device and the user terminal 30 is also bidirectional, including both data transmission from the charging device to the user terminal 30, and data transmission from the user terminal 30 to the charging device, such as control instructions for the charging device.

[0295] On the basis of the above embodiments, referring to Figures 9 and 16, the device system also includes a second device, and the data of the second device can also be transmitted to the user terminal 30 through the first wireless communication module of the central device. The second device is configured as a battery pack charger 50 (that is, the peripheral device system also includes a battery pack charger), and the battery pack charger 50 can communicate with the battery pack 10.

[0296] The battery pack charger 50 includes a charger housing 510, a battery pack charging interface 520 provided on the charger housing 510, and a charging circuit provided in the charger housing 510. The charging circuit is electrically connected to the battery pack charging interface 520. The charging circuit is used to connect to an external AC power source and convert the input AC power into DC power and output it through the battery pack charging interface 520 to charge the battery pack 10 connected to the battery pack charging interface 520.

[0297] When the battery pack 10 is connected to the battery pack charger 50, the battery pack 10 receives and stores data from the battery pack charger 50. When the battery pack 10 is in communication with the hub device, the hub device receives the battery pack data and the battery pack charger data stored in the battery pack and transmits it to the user terminal via the first wireless communication module. It will be understood that the battery pack charger in this embodiment belongs to the aforementioned second category of devices.

[0298] Furthermore, the second device is configured to perform different tasks from the first device and the central device. In this embodiment, the first device is configured as a power tool 40, and the central device is configured as an energy storage charging device 20. The specific implementation of the energy storage charging device 20 can be referred to in the previous embodiment and will not be repeated here.

[0299] Furthermore, the battery pack 10 communicates with the battery pack charger 50 through wired communication to receive data from the battery pack charger 50. Specifically, the battery pack 10 and the battery pack charger 50 are provided with matching wired communication modules. When the battery pack 10 and the battery pack charger 50 are connected, the two exchange data through wired communication. Specifically, the battery pack charger 50 is configured with a charger wired communication module 501, and the battery pack 10 is configured with a battery pack wired communication module 102. Among them, the wired communication module described in this embodiment can be any one of a serial communication module and a CAN communication module. Of course, it can also be other forms of wired transmission modules. Without exceeding the scope of the core idea of ​​the present invention, it also falls within the scope of protection of the present invention. Preferably, the charger wired communication module 501 and the battery pack wired communication module 102 adopt a serial communication module or a CAN communication module.

[0300] The data of the battery pack 10 and the data of the battery pack charger 50 can be transmitted to the user terminal 30 via the first charging device wireless communication module 201 of the energy storage charging device 20 .

[0301] Specifically, when the battery pack 10 is connected to the battery pack charger 50, the battery pack 10 receives and stores data from the battery pack charger 50 via wired communication, while also storing its own data. When the battery pack 10 is communicatively connected to the energy storage charging device 20, the energy storage charging device 20 receives the battery pack data and the battery pack charger data stored in the battery pack and transmits them to the user terminal 30 via the first charging device wireless communication module 201. This enables offline transmission of the battery pack 10 data and the battery pack charger 50 data.

[0302] The specific application scenario of this embodiment is as follows: when the battery pack 10 is connected to the battery pack charger 50, the battery pack 10 is charged by the battery pack charger 50. If the battery pack 10 cannot establish communication with the user terminal 30, the battery pack 10 receives and stores data from the battery pack charger 50 via wired communication, and also stores its own data. When the battery pack 10 is separated from the battery pack charger 50 and reconnected to the charging interface 222 of the energy storage charging device 20 for charging, the energy storage charging device 20 receives the data stored in the battery pack 10 from the battery pack charger 50 and its own data via wired communication, and transmits them to the user terminal 30 via the first charging device wireless communication module 201. Neither the battery pack 10 nor the battery pack charger 50 requires a wireless communication module. The first charging device wireless communication module 201 of the energy storage charging device 20 can transmit the data from the battery pack charger 50 and the battery pack 10 to the user terminal 30, effectively reducing communication costs. In addition, it should be noted that the battery pack 10 cannot establish communication with the user terminal 30. This may be because the battery 10 does not have a communication module that can communicate with the user terminal 30, or it may be that the battery pack 10 has a communication module that can communicate with the user terminal 30, but the distance between the battery pack 10 and the user terminal 30 exceeds the communication distance of the communication module, and therefore communication cannot be established.

[0303] In another embodiment, the device system further includes a third device based on the above embodiment, the first wireless communication module includes a short-range wireless communication module and a long-range wireless communication module, the third device is provided with a second wireless communication module that can be matched and connected with the short-range wireless communication module, and the third device can only communicate with the hub device through the second wireless communication module and the short-range wireless communication module;

[0304] The data of the third device is transmitted to the hub device via the second wireless communication module and the short-range wireless communication module, and then transmitted to the user terminal via the long-range wireless communication module of the hub device. It is understood that the communication distance of the long-range wireless communication module is greater than that of the short-range wireless communication module, and the third device belongs to the aforementioned third category of devices.

[0305] As an example, referring to FIG. 26 , the third device is configured as a battery pack charger 50 , and the battery pack charger 50 is provided with a second battery charger wireless communication module 503 (ie, the second wireless communication module of the aforementioned third device).

[0306] The battery pack charger 50 includes a charger housing 510, a battery pack charging interface 520 provided on the charger housing 510, and a charging circuit provided in the charger housing 510. The charging circuit is electrically connected to the battery pack charging interface 520. The charging circuit is used to connect to an external AC power source and convert the input AC power into DC power and output it through the battery pack charging interface 520 to charge the battery pack 10 connected to the battery pack charging interface 520.

[0307] The data of the battery pack charger 50 can be transmitted to the hub device through the second wireless communication module and the short-range wireless communication module, and transmitted to the user terminal through the long-range wireless communication module of the hub device.

[0308] In this embodiment, the central device is configured as an energy storage charging device 20, which includes a first charging device wireless communication module 201 (that is, a long-distance wireless communication module of the aforementioned first wireless communication module) and a second charging device wireless communication module 203 (that is, a short-distance wireless communication module of the aforementioned first wireless communication module).

[0309] The data of the battery pack charger can be transmitted to the energy storage charging device 20 through the second charger wireless communication module 503 and the second charging device wireless communication module 203, and transmitted to the user terminal through the first charging device wireless communication module 201 of the energy storage charging device 20.

[0310] Furthermore, the first charging device wireless communication module 201 can be configured as a wireless communication module capable of long-distance communication, and can be one of a 3G module, a 4G module, a 5G module, a Lora module, a SigmaFox module, and a NB-IoT module.

A port overload indicates an AC output port overload.

[0346] Take one of the application scenarios of the power manager 70 as an example.

[0347] When gardening teams work outdoors, AC power outlets are often scarce. When multiple electrical devices require AC power, a power manager 70 can be used to direct a single AC power source to multiple AC output terminals 720, providing AC power to multiple devices. For example, the power manager wireless communication module 701 and the charging device wireless communication module 203 both utilize Bluetooth modules.

[0351] Furthermore, the user terminal is configured with an application. When the power manager 70 is connected to the charging device 20, the application can select a method for data interaction between the user terminal 30 and the power manager 70. The methods for data interaction between the user terminal 30 and the power manager 70 include at least: the user terminal 30 directly interacting with the power manager 70, and the user terminal 30 interacting with the power manager 70 through the charging device 20.

[0352] Specifically, when the power manager 70 establishes communication with the user terminal 30 in a data exchange mode, if a switch is needed, the user can manually switch through the application of the user terminal 30.

It is understood that the battery pack belongs to the aforementioned first category of devices, the power tool belongs to the aforementioned second category of devices, and the inverter and power manager belong to the aforementioned third category of devices. It is understood that, as in the aforementioned embodiment, the energy storage charging device 20 is equipped with a long-range communication module and a short-range communication module, and can communicate with the battery pack 10 via wired communication. This enables data exchange between the power tool 40, the battery pack 10, the power manager 70, and the inverter 80, i.e., the aforementioned three categories of devices, and the user terminal 30. Similarly, the battery pack charger 50 of this embodiment can realize data interaction between the power tool 40, the battery pack 10, the power manager 70 and the inverter 80 and the user terminal 30 in the same communication manner, which will not be repeated here.

Preferably, the battery charger 50 includes a Bluetooth module, a 4G module, and a WiFi module. Based on this, the communication method between the various devices in the device system can be inferred from the aforementioned embodiments and will not be further elaborated here.

[0386] It should be noted that the device system of the present application can be any one or more combinations of the aforementioned embodiments.

[0387] In one embodiment, referring to FIG30 , the device system of the present application includes an energy storage charging device 20, a battery pack charger 50, an electric tool 40, a battery pack 10, a power manager 70, an inverter 80, and a garden robot tool 60, i.e., all of the devices described in the aforementioned embodiments. The battery pack charger 50 and the energy storage charging device 20 are both equipped with long-range and short-range wireless communication modules, and can both serve as hub devices to enable data exchange between the aforementioned first, second, and third category devices and the user terminal. The communication method between each device and the user terminal 30 can be inferred from the aforementioned embodiments and will not be further described here.

[0388] In combination with the aforementioned embodiments, it can be seen that in the device system provided by the present application, by providing a wireless communication module capable of long-distance communication in the central device, the central device establishes communication with the user terminal, and can transmit data from the battery pack 10, the power tool 40, the battery pack charger 50, the power manager 70, and the inverter 80 to the user terminal 30, thereby enabling data interaction between all devices in the device system and the user terminal 30. That is, in the device system, a suitable device is selected as the central device, and the central device is used as the communication hub of the device system. The first, second, and third category devices in the device system, as described above, can all achieve data interaction with the user terminal with the help of the wireless communication module of the central device. While enabling monitoring and management of the devices through the user terminal 30, the communication cost of the system can be effectively reduced, avoiding the cost increase caused by configuring wireless communication modules for all devices in the device system.

[0389] In other embodiments, in the device system of the present application, the hub device can also be configured as an inverter 80. The battery pack can be electrically connected to the inverter 80 and discharged through the inverter 80, and the inverter 80 can communicate with the battery pack 10. The battery pack 10 can be connected to the power tool 40 and power the power tool 40, and the battery pack 10 can communicate with the power tool 40. The inverter 80 is provided with an inverter wireless communication module 801.

[0390] The data of the power tool 40 and the data of the battery pack 10 can be transmitted to the user terminal 30 via the inverter wireless communication module 801 of the inverter 80. When the battery pack 10 is connected to the power tool 40, the battery pack 10 receives and stores the data of the power tool 40. When the battery pack 10 is in communication with the inverter 80, the inverter 80 receives the data of the battery pack 10 and the data of the power tool 40 stored in the battery pack 10 and transmits them to the user terminal 30 via the inverter wireless communication module 801.

[0391] The specific implementation of the inverter can be referred to the above embodiment and will not be repeated here. Furthermore, in this embodiment, the inverter 80 communicates with the battery pack 10 via wired communication, preferably using a serial communication module and / or a CAN communication module, and the inverter wireless communication module 801 uses a Bluetooth module.

[0392] In the above embodiments, the parameter types specifically included in the battery pack data, the power tool data, the energy storage charging device data, and the battery pack charger data can refer to the limitations of the aforementioned device component embodiments and will not be repeated here.

[0393] Furthermore, the battery pack data is divided into real-time data and historical data stored in the battery pack based on the real-time nature of the data. The battery pack data received by the device includes real-time data and historical data stored in the battery pack. It should be noted that real-time data refers to the current data after the battery pack is connected to the device, while historical data stored in the battery pack refers to data stored in the battery pack before the battery pack is connected to the device.

[0394] As previously described, the battery pack 10 communicates with the charging device via wired communication. The charging device is equipped with a device wired communication module, and the battery pack 10 is equipped with a battery pack wired communication module 102. Furthermore, the battery pack includes a first battery pack terminal, and the device includes a first device terminal. The first battery pack terminal and the first device terminal are electrically connected to form a data transmission path. Both real-time data from the battery pack and historical data stored in the battery pack are transmitted to the device via this data transmission path.

[0395] In this embodiment, the battery pack 10 includes a charging interface for connecting to a charging interface of a charging device. The battery pack charging interface includes a positive terminal, a negative terminal, an analog signal communication terminal, and a digital signal communication terminal. The charging interface of the charging device includes a positive terminal, a negative terminal, an analog signal communication terminal, and a digital signal communication terminal that match the charging interface of the battery pack.

[0396] As an example, the battery pack's charging interface includes a digital signal communication terminal, namely, the aforementioned first battery pack terminal. The charging device's charging interface also includes a digital signal communication terminal, namely, the aforementioned first charging device terminal. The first battery pack terminal and the first charging device terminal are electrically connected to form a data transmission path, and both the real-time data of the battery pack 10 and the historical data stored in the battery pack 10 are transmitted to the charging device via this data transmission path.

[0397] Specifically, the first battery pack terminal can be configured as a serial port terminal, and the first charging device terminal can be configured as a serial port terminal. The first battery pack terminal is used to electrically connect with the first charging device terminal to form a serial port signal transmission path. The real-time data of the battery pack and the historical data stored in the battery pack 10 are transmitted to the charging device through this serial port signal transmission path.

[0398] Alternatively, the first battery pack terminal and the first charging device terminal are both configured as CAN terminals, the CAN terminals of the battery pack 10 include a first CAN terminal and a second CAN terminal, and the CAN terminals of the charging device include a third CAN terminal and a fourth CAN terminal. The first CAN terminal is electrically connected to the third CAN terminal, and the second CAN terminal is electrically connected to the fourth CAN terminal to form a differential signal transmission path. The real-time data of the battery pack and the historical data stored in the battery pack 10 are both transmitted to the charging device through this differential signal transmission path.

[0399] As another example, the charging interface of the battery pack includes two digital signal communication terminals, and the charging interface of the charging device also includes two digital signal communication terminals.

[0400] Specifically, the two digital signal communication terminals of the battery pack 10 are a serial port terminal and a pair of CAN terminals, respectively, while the two communication terminals of the charging device are a serial port terminal and a pair of CAN terminals. When the battery pack 10 and the energy storage charging device 20 are connected, the serial port terminal of the battery pack 10 and the serial port terminal of the charging device are electrically connected to form a serial port signal transmission path, i.e., a serial port signal transmission path. The pair of CAN terminals of the battery pack 10 and the pair of CAN terminals of the charging device are electrically connected to form a differential signal transmission path. The battery pack 10 and the charging device select either the serial port signal transmission path or the differential signal transmission path to transmit the battery pack's real-time data and historical data stored within the battery pack 10. Furthermore, the differential signal transmission path is preferentially selected to transmit the battery pack's real-time data and historical data stored within the battery pack 10.

[0401] Furthermore, the specific data types included in the real-time data of the battery pack 10 and the historical data stored in the battery pack 10, the specific implementation methods of the charging interface of the charging device and the charging interface of the battery pack, the communication method between the battery pack 10 and the charging device, and the specific transmission method of the real-time data of the battery pack 10 and the historical data stored in the battery pack 10 can be referred to the limitations of the aforementioned device component embodiments and will not be repeated here.

[0402] It should be noted that the communication links of each embodiment of the device system can be set up separately or in combination with the communication links of any embodiment. When a combined setting is adopted, the communication links between the devices in the device system can be enriched, providing more communication paths for the devices to transmit data, thereby effectively ensuring reliable data transmission and reducing communication costs.

[0403] It should be noted that the energy storage charging device 20, battery pack 10, power tool 40, battery pack charger 50, inverter 80, power manager 50, garden robot tool 60, interactive terminal 301, and cloud server 302 in the above embodiment, in addition to the communication module, are also provided with a control module and a storage unit. The control module is electrically connected to the communication module, and the control module is used to transmit data to other devices through the communication module, or to receive data transmitted by other devices through the communication module. The control module is electrically connected to the storage unit, and is used to store the acquired data in the storage unit, or to retrieve the data stored in the storage unit. Specifically, the control module can be configured as a single-chip microcomputer, MCU, etc. with data receiving and processing functions, and the communication module includes a wired communication module and a wireless communication module of each device, which will not be described in detail here.

[0404] It should be noted that the data of the ×× device mentioned in this application (such as battery pack data, power tool data, battery pack charger data, power manager data, inverter data, etc.) should be understood as at least part of the data of the ×× device.

[0405] Furthermore, the power tool 40, battery pack 10, battery pack charger 50, energy storage charging device 20, power manager 70, inverter 80, and garden robot tool 60 in the above-described embodiment are each configured with a unique identification code. The power tool 40, battery pack 10, battery pack charger 50, energy storage charging device 20, power manager 70, inverter 80, and garden robot tool 60 can establish an association with the user terminal 30 via their respective identification codes. In this embodiment, the interactive terminal 301 is configured with an application 301c. This application 301c enables the interactive terminal 301 to associate with the device and establish communication using the device's identification code. Specifically, the identification code is preferably in the form of a serial number, which has a unique corresponding QR code. The QR code is attached to the device in a pasted or printed form. Based on the application 301c, the device can be associated with the application 301c by entering the device serial number or scanning the code. Of course, other methods are also possible, such as searching for devices via Bluetooth, which are not listed here. After the application 301c is associated with the device, the device can establish communication with the user terminal 30, and the status of the device or function control can be performed through the application 301c.

[0406] The device components and equipment systems of the aforementioned embodiments effectively improve the reliability of communication between the battery pack 10, the energy storage charging device 20, the power tool 40, the battery pack charger 50, the power manager 70, and the inverter 80 by rationally configuring communication modules for each device in the device components and equipment system, and rationally configuring the communication methods between the energy storage charging device 20, the battery pack 10, the power tool 40, the battery pack charger 50, the power manager 70, and the inverter 80. This allows users to effectively monitor and manage the energy storage charging device 20, the battery pack 10, the power tool 40, the battery pack charger 50, the power manager 70, and the inverter 80. Furthermore, by efficiently utilizing the communication modules, low costs can be achieved. Furthermore, wired monitoring and management of the garden robot tool 60 can also be performed via the user terminal 30.

[0407] The energy storage charging device 20, battery pack 10, power tool 40, battery pack charger 50, power manager 70, inverter 80, and garden robot tool 60 can store working status data in the user terminal 30 by interacting with the user terminal 30; when the user terminal 30 is provided with a display interface, the corresponding device data can be displayed on the user terminal 30 so that the user can more intuitively know the operating status of the corresponding device; when the user terminal 30 is provided with a control panel or a touch interface, the corresponding device can be remotely controlled by sending configuration data or control instructions through the user terminal 30, so that various functions of the corresponding device can be controlled according to actual needs, such as charging control of the device, device search, etc., which facilitates the user to comprehensively monitor and manage the device.

[0408] In one embodiment, based on the above-mentioned device components or equipment system, the charging mode of the energy storage charging device 20 can be controlled through the user terminal 30 .

[0409] Specifically, referring to Figures 22 and 23, the energy storage charging device 20 is configured with a normal charging mode and a fast charging mode. The output power of a single charging interface in the fast charging mode is greater than the output power of a single charging interface in the normal charging mode. When the user urgently needs to use the battery pack, the fast charging mode can be turned on. When the user does not urgently need to use the battery pack, the normal charging mode can be turned on, which can meet the user's usage needs in different scenarios.

[0410] The interactive terminal 301 is configured with an application 301c, which has a fast charging mode trigger switch. When the user turns on the fast charging mode trigger switch through the application 301c, the interactive terminal 301 sends a fast charging instruction to the energy storage charging device 20 through the second terminal wireless communication module 301b. When the fast charging mode trigger switch is turned off, the interactive terminal 301 sends a normal charging instruction to the energy storage charging device 20 through the second terminal wireless communication module 301b.

[0411] As previously described, the energy storage charging device 20 includes a battery module 210 and a charging module 220. The charging module 220 includes a first charging module 223, a second charging module 224, and multiple charging interfaces 222. Each of the multiple charging interfaces 222 can be connected to the battery pack 10 to charge the battery pack 10. In this embodiment, the first charging module 223 further includes multiple charging units. The input end of each charging unit is electrically connected to the battery module 210, and the output end of each charging unit is connected to at least one charging interface, so that multiple charging units can charge the battery pack 10 simultaneously or separately. The energy storage charging device 20 also includes a control module 226 and a switch module 227. The switch module 227 is connected between the multiple charging units and the multiple charging interfaces and is used to selectively connect the multiple charging units and the multiple charging interfaces. The control module 226 is electrically connected to the switch module 227 and is used to output control signals to control the switching of each switch of the switch module 227. The control module 226 is also used to receive and respond to the charging mode switching instructions sent by the user, and control the energy storage charging device 20 to switch between normal charging mode and fast charging mode, that is, to control the charging interface of the energy storage charging device 20 to output different power to charge the battery pack 10.

[0412] For example, the first charging module 223 may include two charging units, each of which is connected to a charging interface, or each of which is connected to two charging interfaces, or one of the charging units is connected to one charging interface and the other is connected to two charging interfaces. Alternatively, the first charging module 223 may include three charging units, each of which is connected to one or more charging interfaces, etc. The number of charging units and charging interfaces can be set according to the charging requirements and the size of the energy storage charging device 20, and this application does not impose any restrictions.

[0413] As a specific example, as shown in Figure 22, the first charging module 223 includes two charging units, namely a first charging unit 223a and a second charging unit 223b, and the charging interface 222 includes three charging interfaces, namely a first charging interface 222a, a second charging interface 222b, and a third charging interface 222c. The switch module 227 can be a switch network composed of multiple switches. The control module 226 can control the two charging units to output power in parallel or individually to one or more charging interfaces by controlling the multiple switches of the switch module 227 to turn on or off.

[0414] The energy storage charging device 20 is quickly charged and controlled by the user terminal 30, specifically including the following steps:

[0415] Step S231: When the user turns on the fast charging mode trigger switch through the application 301c of the interactive terminal 301, the interactive terminal 301 responds to the user operation and sends a fast charging instruction to the energy storage charging device 20;

[0416] Step S232: After receiving the fast charging instruction, the energy storage charging device 20 starts the fast charging mode;

[0417] Step S233 , the control module 226 determines a control strategy for the switch module 227 based on the charging parameters requested by the battery pack;

[0418] In step S234 , the control module 226 controls the switch module 227 to output electric energy through the fast charging interface to quickly charge the battery pack 10 .

[0419] Specifically, in step S233 , the charging parameter requested by the battery pack may be a requested charging current, a requested charging power, or other parameters representing the charging capability.

[0420] It should be noted that the requested charging parameters of the battery pack 10 are determined by combining the maximum charging parameters that the charging device can output and the maximum charging parameters allowed by the battery pack 10. Therefore, since in fast charging mode, the energy storage charging device 20 can connect the first and second charging units in parallel to output to a single charging interface, while in normal charging mode, the two charging units need to output to multiple charging interfaces. Therefore, the maximum charging parameter that the energy storage charging device 20 can output from a single charging interface in fast charging mode is greater than the maximum charging parameter that the energy storage charging device 20 can output from a single charging interface in normal charging mode. Consequently, the battery pack 10 can select a larger requested charging parameter within its maximum allowed charging parameter range to achieve fast charging.

[0421] In this embodiment, the control strategy for the switch module 227 is determined based on the charging power requested by the battery pack as an example.

[0422] In fast charging mode, the control module 226 obtains the requested charging power of the battery pack 10 and compares it with the maximum output power of a single charging unit. When the requested charging power is less than or equal to the maximum output power of a single charging unit, the output power of a single charging unit can meet the fast charging requirements of the battery pack 10, and the control module 226 controls the single charging unit to charge the battery pack 10. When the requested charging power is greater than the maximum output power of a single charging unit, the combined output power of multiple charging units is required to meet the fast charging requirements. In this case, the control module 226 controls at least two charging units to charge the battery pack 10 in parallel. It should be understood that in fast charging mode, the number of units connected in parallel can be selected based on the requested charging power of the battery pack 10 and is not limited to two. In fast charging mode, the maximum output power of the first charging module 223 is no less than 3.6 kW. For example, the maximum output power of the first charging module 223 can be 3.6 kW, 4 kW, 4.8 kW, 6 kW, or 7.2 kW.

[0423] Specifically, in step S234, a charging interface of the energy storage charging device 20 can be preset as a fast charging interface, or the user can select and set it when starting the fast charging mode. In this embodiment, the first charging interface 222a is preset as a fast charging interface. In the fast charging mode, the energy storage charging device 20 quickly charges the battery pack 10 connected to the first charging interface 222a.

[0424] In normal charging mode, the output power of a single charging unit can meet the charging needs of the battery pack 10, so the control module 226 controls the single charging unit to charge the battery pack 10 connected to its charging interface. Exemplarily, the energy storage charging device 20 charges the battery pack 10 connected to the first charging interface 222a via the first charging unit 131, and / or alternately charges the battery pack 10 connected to the second charging interface 222b and the third charging interface 222c via the second charging unit 132. In normal charging mode, the maximum output power of the charging unit to a single charging interface is not less than 1.8 kW. Exemplarily, the maximum output power of a single charging interface is between 1.8 kW and 3.6 kW. For example, the maximum output power can be 1.8 kW, 2 kW, 2.4 kW, 3 kW, or 3.6 kW.

[0425] In normal charging mode, for a 0.2KWH battery pack 10, the energy storage charging device 20 can be fully charged in 8-15 minutes, and the empty battery pack 10 can be charged to 80% of the rated capacity in 5-12 minutes. For a 0.6KWH battery pack 10, the energy storage charging device 20 can be fully charged in 13-25 minutes, and the empty battery pack 10 can be charged to 80% of the rated capacity in 9-22 minutes. In fast charging mode, for a 0.2KWH battery pack 10, the energy storage charging device can be fully charged in 4-7 minutes, and for a 0.6KWH battery pack 10, the energy storage charging device can be fully charged in 8-15 minutes. Therefore, when the garden team urgently needs the battery pack 10, the fast charging mode can be turned on to reduce the waiting time for electricity.

[0426] Furthermore, in this embodiment, the charging mode switching of the energy storage charging device 20 can be remotely controlled through the user terminal 30, which is convenient for user operation.

[0427] 22 and 24 , based on the aforementioned energy system or device system, economic charging control can be performed on the energy storage charging device 20 via the user terminal 30. Since the power grid has peak and valley electricity price periods, to improve charging efficiency, the energy storage charging device 20 is configured with an economic charging mode to save electricity costs.

[0428] Specifically, the circuit structure of the energy storage charging device 20 is shown in the embodiment of FIG20 , and includes a battery module 210, a second charging module 224, an AC input interface 225, and a control module 226. Preferably, the second charging module 224 uses an AC / DC module, and the control module 226 is connected to and controls the opening and closing of the second charging module 224.

[0429] The interactive terminal 301 is equipped with an application 301c, which includes an entry for configuring economic charging mode data and an entry for triggering economic charging mode. The entry for configuring economic charging mode data includes an entry for setting low-cost periods and a entry for setting a maximum charging end time. Users can use the low-cost periods and maximum charging end time settings in application 301c to configure economic charging parameters. The maximum charging end time is the user-set time when the user next needs to use the energy storage charging device 20. The economic charging mode trigger is used to send an economic charging instruction to the charging device 20 in response to a user trigger operation.

[0430] When the user triggers the economic charging mode entry through the application, the interactive terminal 301 sends an economic charging instruction to the energy storage charging device 20 via the second terminal wireless communication module 301b. The energy storage charging device 20 receives the economic charging instruction, saves the economic charging parameters, activates the economic charging mode, and then determines the current economic charging status.

[0431] When economic charging is turned on but has not entered the valley time period, the energy storage charging device 20 calculates the time length T1 required for the battery module 210 to be fully charged and the valley time period length T2 before the latest charging end time, and compares the two. When the time length T1 required for the battery module 210 to be fully charged is greater than the valley time period length T2 before the latest charging end time, the energy storage charging device 20 calculates the economic charging start time point and starts economic charging at this time point, where the economic charging start time point t = the valley time period start time point t1 - (T1 - T2); otherwise, economic charging starts at the valley time period start time point t1.

[0432] When economic charging is turned on and the vehicle has entered the trough period, it will immediately enter economic charging.

[0433] When the economical charging is turned off, the battery module 210 is charged using the AC power supply as normal.

[0434] Specifically, after receiving the economic charging instruction, the energy storage charging device turns off the second charging module, namely the ACDC module. When it is determined that immediate charging is required or when the calculated start time arrives, the second charging module is turned on and enters the economic charging mode to charge the battery module through AC power.

[0435] This embodiment can effectively improve the economy of charging by setting an economic charging mode. Furthermore, by setting the latest charging time and calculating the most economical and fully charged time period based on the low electricity price period, the latest charging end time and the user's own power information, the user can ensure that the battery module 210 of the energy storage charging device 20 can be fully charged before the set latest charging end time, which is convenient for the user's subsequent use. Furthermore, if the energy storage charging device 20 does not start charging at the calculated charging start time, or a power outage occurs when the battery is not fully charged, the control module 226 will send a charging reminder message to the user terminal 30, reminding the user to check the reason for not starting charging or abnormal power outage, so as to avoid the device not being charged due to the user forgetting to plug in or other abnormalities affecting subsequent use.

[0436] It should be noted that the economical charging control is not only applicable to the energy storage charging device 20 , but also to the garden robot tool 60 , which are not listed here one by one.

[0437] In one embodiment, based on the above-mentioned device components or equipment system, the device search function can be implemented through the user terminal 30.
