[0052] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0053] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0054] Please see Figures 1 to 14As shown, in this embodiment, the present invention proposes a battery and power tool management method and system to solve the aforementioned related problems. Specifically, the management system 100 includes a pairing module 10, an information query module 20, a connection query module 30, an upgrade module 40, and an interface display module 50. The pairing module 10 is used to pair the management system 100 with the battery 200 and / or the power tool to establish communication between the management system 100 and the battery 200 and / or the power tool. The information query module 20 is used to send a query command to the battery and / or the power tool after the management system is paired with the battery and / or the power tool to obtain the battery information. The system retrieves and / or displays the first information of the battery 200 and / or the power tool, determines whether the status of the battery 200 and / or the power tool is normal, and displays this information on the user interface. The connection query module 30 sends a query command to the battery to determine whether the battery 200 is connected to a power tool or charger. The upgrade module 40 sends an upgrade firmware command to the battery 200 and / or the power tool to update the firmware of the battery and / or the power tool. The interface display module 50 displays the first information and status of the battery 200 and / or the power tool, whether the battery is connected to a power tool or charger, and the firmware update progress of the battery and / or the power tool.

[0055] Please see Figures 1 to 4 As shown, in this embodiment, the management method includes:

[0056] The management system is paired with the battery and / or the power tool via the pairing module 10 to establish communication between them, facilitating data transmission. For example, the management system and the battery and / or the power tool can be paired via Bluetooth, or they can communicate over a network via the wireless communication devices of the management system and the battery and / or the power tool. The communication methods between the management system and the battery and / or the power tool include, but are not limited to, radio waves, Bluetooth, NFC (Near Field Communication), Wi-Fi, ZigBee, LoRa (Long Range Radio), LoRaWAN, Sigfox, etc.

[0057] Please see Figure 1 and Figure 2 As shown, in this embodiment, the management system and the battery are directly paired to establish communication; then the battery is connected to the power tool, so that the battery and the power tool establish communication, thereby realizing communication and data transmission between the management system and the power tool.

[0058] It should be noted that in the various management methods of the following embodiments, the management system sending corresponding instructions to the battery and / or the power tool to perform corresponding actions is based on the pairing and communication established between the management system and the battery and / or the power tool.

[0059] Please see Figures 1 to 6 As shown, in this embodiment, the management method includes:

[0060] After the management system completes pairing and establishes communication with the battery and / or the power tool, the information query module 20 in the management system sends a query command to the battery and / or the power tool to obtain the first information of the battery and / or the power tool, and determines whether the status of the battery and / or the power tool is normal. The normal or abnormal status and the first information are then returned to the management system and displayed on the user interface through the interface display module 50.

[0061] Please see Figures 1 to 6 As shown, in this embodiment, the management system can send a query command to the battery to obtain the battery's first information, such as the battery's temperature, power level, and lock status information, and determine whether the battery's current state is normal. The interface display module 50 displays the battery's temperature, power level, and lock status information on the user interface, and simultaneously displays whether the current battery state is normal or abnormal.

[0062] Please see Figures 1 to 6 As shown, in this embodiment, the management system can send a query command to the power tool to obtain first information about the power tool, such as the tool's total battery level, cutting mode, motor status, angle sensor status, speed, current continuous working time, and remaining battery life. The system can also determine whether the current state of the power tool is normal, and display the information such as the power tool's total battery level, cutting mode, current continuous working time, and remaining battery life on the user interface through the interface display module 50. At the same time, the system can also display whether the current state of the power tool is normal or abnormal, as well as the time when the abnormality occurred.

[0063] For example, please see Figure 7 As shown, the user interface displays detailed information about the current power tool, including its name, model, serial number, firmware version, etc.

[0064] For example, please see Figure 8 As shown, an error list is displayed on the user interface, which details the abnormal states that occurred in the power tools and / or batteries and the times when the abnormal states occurred.

[0065] From the above embodiments, the management system allows users to intuitively view and query relevant information and status of batteries and / or power tools. If the battery and / or power tool malfunctions, the management system can also promptly notify the user to improve safety and facilitate better use of the power tool.

[0066] Please see Figure 2 , Figure 3 and Figure 5 As shown in this embodiment, the management system can also send lock and unlock commands to the battery to lock or unlock the battery, and the interface display module 50 displays whether the battery is in a locked or unlocked state on the user interface, so that the user can control the battery individually.

[0067] Please see Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the management method further includes:

[0068] The management system sends a query command to the battery via the connection query module 30 to obtain the connection status of the battery with a power tool or charger. For example, if the battery is not connected to a power tool, the interface display module 50 displays only the battery's information and status on the user interface; if the battery is connected to a power tool, the interface display module 50 displays the battery's information and the power tool connected to it on the user interface.

[0069] Please see Figure 2 , Figures 3 to 7 , Figure 9 As shown, in this embodiment, the management method further includes:

[0070] The management system sends an upgrade firmware command to the battery and / or the power tool through the upgrade module 40 to update the firmware of the battery and / or the power tool. Specifically, the steps for updating the firmware of the battery and / or the power tool include:

[0071] S101. Obtain the current firmware version of the battery and / or the power tool, and determine whether the current firmware version is the latest version. For example, the upgrade module 40 can send a version query command to the battery and / or the power tool to obtain the current firmware version of the battery and / or the power tool, and determine whether the current version is the latest version.

[0072] S102. If it is not the latest version, obtain the latest version update package and send an upgrade firmware command to the battery and / or the power tool, so that the battery and / or the power tool enters the upgrade mode; for example, the latest version update package can be obtained from the server through the upgrade module 40 and an upgrade firmware command can be sent to the battery and / or the power tool, so that the battery and / or the power tool enters the upgrade mode.

[0073] S103. Send the update package to the battery and / or the power tool to update the firmware of the battery and / or the power tool, obtain the update progress of the battery and / or the power tool, and display it on the user interface. For example, the update module 40 sends the latest version update package to the battery and / or the power tool. After receiving all the contents of the update package, the battery and / or the power tool automatically updates, and the interface display module 50 displays the update progress of the battery and / or the power tool on the user interface.

[0074] Please see Figure 2 , Figures 3 to 7 , Figure 10 and Figure 11 As shown, in this embodiment, the battery and / or the power tool upgrade mode includes an official upgrade mode and a custom upgrade mode, wherein:

[0075] Please see Figure 10 As shown, if it is an official upgrade mode, the firmware update process includes:

[0076] S201, The management system sends an upgrade preparation command to the battery and / or the power tool through the upgrade module 40, so that the battery and / or the power tool enter the upgrade preparation mode;

[0077] S202, the upgrade module 40 sends a first instruction to the battery and / or the power tool, causing the battery and / or the power tool to enter the official upgrade mode;

[0078] S203, the upgrade module 40 sends the update package to the battery and / or the power tool to upgrade the battery and / or the power tool. After receiving all the contents of the update package, the battery and / or the power tool automatically updates, and the update progress of the battery and / or the power tool is displayed on the user interface through the interface display module 50.

[0079] Please see Figure 11As shown, in the custom upgrade mode, the update package is divided into multiple sub-update packages according to a preset number of bytes. These sub-update packages are transmitted one by one to the battery and / or power tool until all sub-update packages have been transmitted. This improves the stability of the update package transmission process, ensuring the smooth completion of the update process and preventing data loss due to transmission interruptions. Specifically, the firmware update process includes:

[0080] S301, The management system sends an upgrade preparation command to the battery and / or the power tool through the upgrade module 40, so that the battery and / or the power tool enters the upgrade preparation mode;

[0081] S302, The upgrade module 40 divides the update package into multiple sub-update packages according to a preset number of bytes;

[0082] S303, The upgrade module 40 sends a second instruction to the battery and / or the power tool, causing the battery and / or the power tool to enter a custom upgrade mode, and transmits the sub-update package to the battery and / or the power tool;

[0083] S304. Obtain a notification that the sub-update package transmission is complete, and then transmit the next sub-update package to the battery and / or the power tool.

[0084] S305. Repeat steps S303 and S304 until all sub-update packages are transmitted to upgrade the battery and / or the power tool. After all sub-update packages are transmitted, the upgrade module sends a transmission completion notification to the battery and / or the power tool to notify that the battery and / or the power tool update package transmission is complete, and the battery and / or the power tool is upgraded according to the update package.

[0085] It should also be noted that during the battery and / or power tool update process, the update progress of the battery and / or power tool is displayed on the user interface through the interface display module 50.

[0086] It should also be noted that before updating or upgrading the battery and / or the power tool, the battery's broadcast data 10 bytes need to be obtained through the upgrade module 40. The upgrade mode is selected based on the data 10 bytes. If it is 1, the official upgrade mode is selected; if it is 2, the custom upgrade mode is selected.

[0087] In some other embodiments, during the update process of the power tool, the update instructions and update package need to be sent to the battery first, and then forwarded to the power tool by the battery, so as to realize the update and upgrade of the power tool.

[0088] In the above embodiments, the management system can upgrade the firmware of the battery and / or power tools, avoiding the problem that traditional garden tools cannot be intelligently updated with firmware, thus failing to bring users the new functions included in the new firmware, and requiring the purchase of new tools, resulting in resource waste. Furthermore, the update progress of the battery and / or the power tools can be displayed on the user interface, which helps users to make better use of the power tools.

[0089] Please see Figure 2 , Figure 3 , Figure 12 and Figure 13 As shown, in this embodiment, the management method further includes:

[0090] S401. Obtain the usage time of easily worn parts on the power tool, and determine whether the usage time is greater than the preset replacement time;

[0091] Please see Figure 2 , Figure 3 , Figure 12 and Figure 13 As shown, the information query module 20 obtains the usage time of a certain vulnerable part on the power tool. This usage time is calculated from the first use of the vulnerable part, and it is determined whether the usage time is greater than a preset replacement time. In this embodiment, the preset replacement time is set to, for example, 15 days. It should be noted that in some other embodiments, the time the power tool is in an unused state is not included in the usage time.

[0092] S402. If so, notify the user to replace the consumable part. After the replacement is completed, the management system recalculates the service life of the consumable part.

[0093] Please see Figure 2 , Figure 3 , Figure 12 and Figure 13 As shown, if the usage time exceeds the preset replacement time, the user is notified to replace the consumable part. After replacement, the management system is notified to complete the replacement, allowing the management system to recalculate the usage time of the consumable part. The usage time of the consumable part is then displayed in the user interface through the interface display module 40. For example, the user interface may display a consumables and maintenance interface, which records the current status or remaining lifespan of each component in detail to promptly remind the user to replace it.

[0094] In the above embodiments, the management system can display the usage time of the consumable parts in the user interface, so that users can intuitively view the usage time of each consumable part, thereby reminding users to replace the consumable parts in a timely manner, which helps users to make better use of the power tool.

[0095] Please see Figure 1 As shown, in this embodiment, the management method further includes:

[0096] The management system retrieves the location of the power tool at preset intervals, such as every 5 minutes, and displays the location of the power tool on the user interface so that the management system can obtain the location information of the last time the tool was used, making it convenient for the user to find the tool.

[0097] Please see Figure 1 and Figure 14 As shown, in this embodiment, the management method further includes:

[0098] The management system can display the cumulative usage time of the power tool and the reduced carbon dioxide emissions on the user interface through the interface display module 40. In some other embodiments, the user interface can also display the amount of carbon dioxide emissions reduced by the power tool equivalent to the number of trees that were not felled, so that users can intuitively feel the energy-saving and emission-reduction effect and improve their environmental awareness.

[0099] Please see Figure 3 As shown, in this embodiment, the management method further includes:

[0100] The management system sends a PCB serial number retrieval command to the battery, and then forwards the command to the power tool via the battery to obtain the power tool's PCB serial number. This allows the user to view each battery and its corresponding power tool, facilitating user management of both. The management system compares the retrieved PCB serial number with data in its database to determine the type of power tool.

[0101] Please see Figure 1 As shown, in this embodiment, the management method further includes:

[0102] An energy-saving command is sent to the power tool. Upon receiving the command, the power tool returns to charging and automatically shuts down upon completion of charging. Specifically, the management system sends an energy-saving command to the paired power tool. Upon receiving the command, the power tool returns to charging and automatically shuts down upon completion of charging, disconnecting the power tool from the server and turning off all indicator lights to achieve energy saving. The server is used to store user data, forward commands from the management system to the power tool to drive it to perform corresponding tasks, and return the execution results to the management system after the power tool completes the execution.

[0103] In the above embodiments, users can remotely activate the energy-saving mode through the management system, so that the lawnmower returns to the charging station to charge and automatically shuts off after being fully charged, in order to prevent the battery from running low on power, thereby avoiding increased battery wear and shortening battery life, and at the same time avoiding energy waste.

[0104] In summary, this invention proposes a management method and system for batteries and power tools. The management system allows users to intuitively view and query relevant information and status of batteries and / or power tools. If a battery or power tool malfunctions, the management system can promptly notify the user to improve safety. Furthermore, the management system can upgrade the firmware of batteries and / or power tools, and it can display the usage time of consumable parts in the user interface, allowing users to intuitively view the usage time of each consumable part and thus promptly reminding them to replace it. This facilitates better management and utilization of the batteries and power tools.

[0105] This invention proposes a battery and power tool management method and system. Through the management system, users can remotely activate the energy-saving mode, which allows the lawnmower to return to the charging station for charging. Once fully charged, the lawnmower will automatically shut down to prevent the battery from running low on power, thereby avoiding increased battery wear and shortening battery life, and also preventing energy waste.
