[0044] Figure 3 A schematic flow chart of the battery management method for an electric two-wheeled vehicle provided in this application.

[0045] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0046] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0047] As described in the background technology, the current lead-acid battery management system mainly manages the battery voltage, current and temperature. It cannot monitor the modification behavior and the installation of third-party batteries, and cannot effectively trace the original factory batteries, which brings great inconvenience to after-sales service.

[0048] The battery management method for an electric two-wheeled vehicle provided by the present application stores the identity information of the original battery group in the passive radio frequency identification tag on the original battery group in the electric two-wheeled vehicle. It is possible to determine whether the original battery group in the electric two-wheeled vehicle has been modified by reading the identity information of the battery group in the electric two-wheeled vehicle through the passive radio frequency identification reader in the battery management module. This enables the battery management module to perform identity recognition and authentication of the battery group at a low cost, effectively monitor modification behavior or third-party battery installation behavior, effectively conduct anti-counterfeiting and traceability of original batteries, and reduce the inconsistencies caused by after-sales service.

[0049] Figure 1 The schematic diagram of the structure of the electric bicycle provided in this application is as follows: Figure 1 As shown, the electric bicycle includes a battery management module 101 and a plurality of battery packs 102 (for example, four battery packs), the battery packs include battery cell groups, the battery cell groups are provided with passive radio frequency identification tags, and the battery management module 101 is provided with a passive radio frequency identification reader. The battery management module 101 is electrically connected to the battery cell groups in each battery pack 102, and the battery management module 101 can communicate with the radio frequency antenna in the passive radio frequency identification tag through the radio frequency antenna in the radio frequency identification reader. Therefore, the battery management module 101 can intermittently read the passive radio frequency identification tag on the battery cell group in the electric two-wheeled vehicle through the passive radio frequency identification reader in the battery management module. In the case that the passive radio frequency identification reader in the battery management module 101 fails to read the identity information of the battery cell group in the electric two-wheeled vehicle within a preset time, it is determined that the identity information of the battery cell group in the electric two-wheeled vehicle has failed to be read, and the corresponding information is reported to the server using the communication module on the electric two-wheeled vehicle, so as to determine that the original battery cell group in the electric two-wheeled vehicle has been modified.

[0050] Figure 2 A structural schematic diagram of the electric motorcycle provided in this application. The battery management method of the electric motorcycle is similar to that of the electric bicycle. The difference is that the number of battery packs of the electric motorcycle is greater than that of the electric bicycle to meet the higher energy and performance requirements of the electric motorcycle.

[0051] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0052] Figure 3 A flow chart of the battery management method for an electric two-wheeled vehicle provided in this application, such as Figure 3 As shown, the battery management method for an electric two-wheeled vehicle (e.g., an electric bicycle, an electric motorcycle, etc.) provided in the present application is applicable to a battery management module, in which a passive radio frequency identification reader is integrated, and the method comprises:

[0053] S101, intermittently reading a passive radio frequency identification tag on a battery pack in an electric two-wheeled vehicle through a passive radio frequency identification reader in a battery management module.

[0054] Among them, the passive radio frequency identification (RFID) tag on the original battery pack in the electric two-wheeled vehicle stores the identity information of the original battery pack; the battery management module is used to be electrically connected to the original battery pack.

[0055] For example, the battery management module may include a lead-acid battery management module, and accordingly, the battery cell group includes a lead-acid battery cell group; the battery management module may also include other battery management modules, such as a lithium battery management module, and accordingly, the battery cell group includes a lithium battery cell group.

[0056] In practical applications, the battery pack may include multiple battery cells connected in series or multiple battery cells connected in parallel. The number of battery cells may be determined based on voltage and capacity requirements.

[0057] In the embodiment of the present application, a passive RFID tag is provided on the original battery cell group in the electric two-wheeled vehicle, and the passive RFID tag on the original battery cell group stores the identity information of the original battery cell group. The passive RFID tag does not require a built-in power supply, has a low manufacturing cost, and its life span mainly depends on physical wear and environmental conditions, and has a long life span. In addition, a passive RFID reader is integrated in the battery management module, and the passive RFID reader can communicate with the passive RFID tag and read the information stored in the passive RFID tag. Then, the passive RFID tag on the battery cell group in the electric two-wheeled vehicle can be read by the passive RFID reader in the battery management module.

[0058] It should be noted that, when the original battery cell group in the electric two-wheeled vehicle has not been modified, the battery cell group in the electric two-wheeled vehicle is the original battery cell group; when the original battery cell group in the electric two-wheeled vehicle has been modified, the battery cell group in the electric two-wheeled vehicle is the modified battery cell group.

[0059] Accordingly, when the passive RFID reader in the battery management module reads the passive RFID tag on the battery pack in the electric two-wheeled vehicle, if the battery pack in the electric two-wheeled vehicle is the original battery pack and the battery management module is electrically connected to the original battery pack, the passive RFID reader can read the identity information of the battery pack in the electric two-wheeled vehicle. When the passive RFID reader in the battery management module reads the passive RFID tag on the battery pack in the electric two-wheeled vehicle, if the battery pack in the electric two-wheeled vehicle is a modified battery pack, no passive RFID tag is set on the modified battery pack, or a passive RFID tag is set on the modified battery pack but the passive RFID tag does not store the identity information of the modified battery pack, the passive RFID reader in the battery management module cannot read the identity information of the battery pack in the electric two-wheeled vehicle.

[0060] For example, the identity information of the battery pack may include the manufacturer, the production time, the serial number (SN), etc.

[0061] In some examples, the passive RFID tag on the battery cell group in the electric two-wheeled vehicle can be periodically read by the passive RFID reader in the battery management module, for example, the passive RFID tag on the battery cell group in the electric two-wheeled vehicle is read once every ten minutes; the passive RFID tag on the battery cell group in the electric two-wheeled vehicle can also be non-periodically read by the passive RFID reader in the battery management module.

[0062] S102. When the passive radio frequency identification reader in the battery management module fails to read the identity information of the battery cell group in the electric two-wheeled vehicle within a preset time, it is determined that the reading of the identity information of the battery cell group in the electric two-wheeled vehicle has failed, and the corresponding information is reported to the server by using the communication module on the electric two-wheeled vehicle to determine whether the original battery cell group in the electric two-wheeled vehicle has been modified.

[0063] For example, if the original battery cell group in the electric two-wheeled vehicle is modified, and no passive radio frequency identification tag is set on the modified battery cell group, or a passive radio frequency identification tag is set but the identity information of the modified battery cell group is not stored, the passive radio frequency identification reader in the battery management module cannot read the identity information of the battery cell group in the electric two-wheeled vehicle.

[0064] Therefore, in this step, when the passive radio frequency identification reader in the battery management module cannot read the identity information of the battery cell group in the electric two-wheeled vehicle within a preset time, it is determined that the reading of the identity information of the battery cell group in the electric two-wheeled vehicle has failed.

[0065] In some embodiments, if the passive radio frequency identification reader in the battery management module fails to read the identity information of any battery cell group within a preset time, it is determined that the reading of the identity information of the battery cell group in the electric two-wheeled vehicle has failed.

[0066] In other embodiments, considering that the original battery cell group in the electric two-wheeled vehicle has been modified, a passive radio frequency identification tag is provided on the modified battery cell group, and the passive radio frequency identification tag stores the identity information of the modified battery cell group. At this time, the passive radio frequency identification reader in the battery management module can read the identity information of the battery cell group in the electric two-wheeled vehicle, but the read identity information is not the identity information of the original battery cell group. If it is determined that the original battery cell group in the electric two-wheeled vehicle has not been modified, it will lead to an erroneous judgment.

[0067] Therefore, when the passive radio frequency identification reader in the battery management module reads the identity information of the battery cell group in the electric two-wheeled vehicle, the read identity information of the battery cell group is compared with the identity information of the battery cell group stored in the battery management module. If the two are inconsistent, it is determined that the reading of the identity information of the battery cell group in the electric two-wheeled vehicle has failed, thereby being able to more accurately determine whether a modification event has occurred.

[0068] Correspondingly, when the identity information of the battery cell group read is consistent with the identity information of the battery cell group stored in the battery management module, it is determined that the identity information of the battery cell group in the electric two-wheeled vehicle is read successfully, so as to determine that the original battery cell group in the electric two-wheeled vehicle has not been modified.

[0069] In this step, after determining that the identity information of the battery pack in the electric two-wheeled vehicle has failed to be read, the communication module in the electric two-wheeled vehicle is used to report corresponding information to the server to determine that the original battery pack in the electric two-wheeled vehicle has been modified.

[0070] In some embodiments, the battery management module can be used to determine whether a modification event has occurred in the original battery group in the electric two-wheeled vehicle. Specifically, when it is determined that the identity information of the battery group in the electric two-wheeled vehicle has failed to be read, information about the modification event of the original battery group is generated, and the information about the modification event of the original battery group is reported to the server, so that the server records the modification event of the original battery group in the electric two-wheeled vehicle, thereby being able to effectively monitor the modification behavior and the third-party battery loading behavior, and provide guarantees for battery after-sales and anti-counterfeiting traceability. For example, when the modified battery group in the electric two-wheeled vehicle fails, it can be proved that the modified battery group has been modified. Among them, the information about the modification event of the original battery group may include modification event identification information, original battery group identity information, and electric two-wheeled vehicle identification information. Accordingly, the corresponding information reported to the server includes information about the modification event of the original battery group.

[0071] In other embodiments, the server can be used to determine whether the original battery cell group in the electric two-wheeled vehicle has been modified. Specifically, when it is determined that the reading of the identity information of the battery cell group in the electric two-wheeled vehicle has failed, the reading failure identification information, the original battery cell group identity information, and the electric two-wheeled vehicle identification information are reported to the server, so that the server determines that the original battery cell group in the electric two-wheeled vehicle has been modified based on the reading failure identification information, the original battery cell group identity information, and the electric two-wheeled vehicle identification information, and records the modification event of the original battery cell group in the electric two-wheeled vehicle. Accordingly, the corresponding information reported to the server includes the reading failure identification information, the original battery cell group identity information, and the electric two-wheeled vehicle identification information.

[0072] In some embodiments, after determining that the identity information of the battery pack in the electric two-wheeled vehicle is read successfully, the communication module in the electric two-wheeled vehicle can also be used to report corresponding information to the server to determine that the original battery pack in the electric two-wheeled vehicle has not been modified. The corresponding information here can include the reading success identification information, the original battery pack identity information and the electric two-wheeled vehicle identification information.

[0073] In some examples, the communication module may include a Bluetooth module or a network module to simplify operations and improve transmission efficiency. For example, the corresponding information can be sent to a mobile terminal bound to the electric two-wheeled vehicle through the Bluetooth module, and the corresponding information can be sent to a server through the mobile terminal. The corresponding information can also be sent to a mobile terminal bound to the electric two-wheeled vehicle through the network module, and the corresponding information can be sent to a server through the mobile terminal. The Bluetooth module can send the corresponding information to the mobile terminal through classic Bluetooth or low-power Bluetooth. The network module can send the corresponding information to the mobile terminal through wifi.

[0074] In other examples, the communication module may also include a cloud box (TBOX), a 4G card, a 5G card, etc.

[0075] In some embodiments, there are multiple original battery cell groups in the electric two-wheeled vehicle and each battery cell group is packaged independently, and the passive radio frequency identification tag on each original battery cell group stores the identity information of the corresponding battery cell group. The passive radio frequency identification card reader in the battery management module can intermittently read the passive radio frequency identification tag on each battery cell group in the electric two-wheeled vehicle to determine whether each battery cell group has been modified, so that the battery management module can realize the identity authentication of each battery cell group at a low cost, and effectively monitor the modification behavior or the third-party battery loading behavior.

[0076] Specifically, the passive RFID reader in the battery management module can intermittently read the passive RFID tag on each battery pack in the electric two-wheeled vehicle. For any battery pack, if the passive RFID reader fails to read the identity information of the battery pack within a preset time, it is determined that the reading of the identity information of the battery pack fails, and the communication module on the electric two-wheeled vehicle can be used to report the corresponding information to determine that the battery pack has been modified.

[0077] For example, the number of the original battery cell groups may be 4 to 6, for example, the number of the original battery cell groups in an electric bicycle is 4, and the number of the original battery cell groups in an electric motorcycle is 6.

[0078] The battery management method for an electric two-wheeled vehicle provided in an embodiment of the present application is characterized in that a passive radio frequency identification tag is provided on the original battery cell group in the electric two-wheeled vehicle, and the passive radio frequency identification tag stores the identity information of the original battery cell group. A passive radio frequency identification reader is integrated in the battery management module, and the passive radio frequency identification tag on the battery cell group in the electric two-wheeled vehicle can be read by the passive radio frequency identification reader in the battery management module. When the identity information of the battery cell group in the electric two-wheeled vehicle is not read within a preset time, it is determined that the reading of the identity information of the battery cell group in the electric two-wheeled vehicle has failed, and corresponding information is reported to the server to determine whether the original battery cell group in the electric two-wheeled vehicle has been modified, thereby realizing the low-cost identity recognition and authentication of the battery cell group by the battery management module, effectively monitoring the modification behavior or the third-party battery installation behavior, and effectively anti-counterfeiting and tracing the original factory-installed battery, thereby reducing the inconsistencies caused by after-sales.

[0079] Another embodiment of the present application provides a battery management method for an electric two-wheeled vehicle. After step S102 in the above embodiment, the method further includes at least one of the following steps:

[0080] S103. When it is determined that the original battery pack in the electric two-wheeled vehicle has been modified based on the information that the identity information of the battery pack in the electric two-wheeled vehicle has failed to be read, the information that the original battery pack has been modified is sent to the control system of the electric two-wheeled vehicle, so that the control system of the electric two-wheeled vehicle controls the instrument on the electric two-wheeled vehicle to display a warning message that the original battery pack has been modified.

[0081] In this step, when it is determined that the original battery pack in the electric two-wheeled vehicle has been modified, the battery management module sends information about the modification event of the original battery pack to the control system of the electric two-wheeled vehicle, so as to display the alarm information of the modification event of the original battery pack on the instrument in the electric two-wheeled vehicle, so as to promptly remind the user that the original battery pack in the electric two-wheeled vehicle has been modified. The modification event information may include modification event identification information, original battery pack identity information, and electric two-wheeled vehicle identification information.

[0082] S104. When it is determined that a modification event has occurred to the original battery pack in the electric two-wheeled vehicle based on the information that the identity information of the battery pack in the electric two-wheeled vehicle has failed to be read, the information that the modification event has occurred to the original battery pack is sent to the control system of the electric two-wheeled vehicle, so that the control system of the electric two-wheeled vehicle controls the motor of the driving wheel to cut off power.

[0083] In this step, when it is determined that the original battery pack in the electric two-wheeled vehicle has been modified, the battery management module sends information about the modification of the original battery pack to the control system of the electric two-wheeled vehicle, so that the control system controls the motor of the drive wheel to cut off the power, so as to control the electric two-wheeled vehicle not to move, thereby timely reminding the user that the original battery pack in the electric two-wheeled vehicle has been modified. The modification event information may include modification event identification information and power-off indication information of the motor controlling the drive wheel.

[0084] It should be noted that when it is determined that the original battery pack in the electric two-wheeled vehicle has been modified based on the information that the identity information in the electric two-wheeled vehicle has failed to be read, step S103 may be executed, step S104 may be executed, or both may be executed.

[0085] The battery management method for an electric two-wheeled vehicle provided in the embodiment of the present application, when it is determined that the original battery pack in the electric two-wheeled vehicle has been modified, controls the instrument on the electric two-wheeled vehicle to display an alarm message that the original battery pack has been modified, and can also control the power supply of the motor of the driving wheel to cut off the power, so as to promptly notify the user that the original battery pack in the electric two-wheeled vehicle has been modified, thereby protecting the rights and interests of the user.

[0086] Another embodiment of the present application provides a battery management method for an electric two-wheeled vehicle. After step S101 in the above embodiment, the method further includes the following steps:

[0087] S106. When the passive radio frequency identification tag reader in the battery management module successfully reads the identity information of the battery pack in the electric two-wheeled vehicle within a preset time, the battery status information of the battery pack in the electric two-wheeled vehicle is written into the passive radio frequency identification tag on the battery pack in the electric two-wheeled vehicle.

[0088] The battery status information includes at least one of the number of cycles, health status and activation time.

[0089] In this step, the passive radio frequency identification tag on the battery pack in the electric two-wheeled vehicle is used to record key information such as the number of cycles, state of health (SOH), activation time, etc. of the battery pack in the electric two-wheeled vehicle, so that the battery status information can be quickly obtained during maintenance and inspection, further providing protection for battery after-sales and anti-counterfeiting traceability.

[0090] In some embodiments, the number of original battery cell groups in the electric two-wheeled vehicle may be multiple, and if each original battery cell group has not been modified, the passive radio frequency identification reader in the battery management module can successfully read the identity information of each battery cell group in the electric two-wheeled vehicle within a preset time. If the passive radio frequency identification reader in the battery management module successfully reads the identity information of each battery cell group in the electric two-wheeled vehicle within a preset time, the battery status information of each battery cell group in the electric two-wheeled vehicle is written into the passive radio frequency identification tag on the corresponding battery cell group.

[0091] Accordingly, when it is necessary to inspect the battery pack, the passive RFID reader in the battery management module can read the passive RFID tag on each battery pack, and determine whether each battery pack is abnormal based on the battery status information read from the passive RFID tag. When an abnormality occurs in the battery pack, the communication module on the electric two-wheeled vehicle can be used to report the corresponding information to the server so that the abnormal battery pack can be repaired or replaced in time. For example, the identification information of the abnormal battery pack and the electric vehicle identification information can be reported to the server.

[0092] Another embodiment of the present application provides a battery management method for an electric two-wheeled vehicle. Before step S101 in the above embodiment, the method further includes the following steps:

[0093] S107, sending a radio signal through the passive radio frequency identification reader in the battery management module.

[0094] Among them, the passive radio frequency identification tag on the battery pack in the electric two-wheeled vehicle can send a response signal after receiving the radio signal sent by the passive radio frequency identification reader.

[0095] S108, upon receiving a response signal from the passive radio frequency identification tag on the battery pack, establishing a reading channel between the passive radio frequency identification reader and the battery pack, and encrypting the reading channel.

[0096] Accordingly, the passive RFID reader in the battery management module can intermittently read the passive RFID tag on the battery pack in the electric two-wheeled vehicle according to the encrypted reading channel. The passive RFID tag on the battery pack in the electric two-wheeled vehicle can be intermittently read according to the encrypted reading channel.

[0097] In some embodiments, when there are multiple battery packs in the electric two-wheeled vehicle, a reading channel can be established between the passive RFID reader and the passive device identification tag on each battery pack, and each reading channel can be encrypted. Then, the passive RFID reader in the battery management module can intermittently read the passive RFID tag on the corresponding battery pack according to each encrypted reading channel.

[0098] In this embodiment, a reading channel is established between the passive RFID reader and the passive RFID tag on the battery pack, and the reading channel is encrypted. When the passive RFID tag is read using the reading channel, data security can be improved.

[0099] The present application also provides a battery management module, including a passive radio frequency identification reader, a controller and a memory, wherein a computer program is stored in the memory. When the computer program is executed by a processor, the controller executes the above-mentioned battery management method for an electric two-wheeled vehicle to determine whether an original battery cell group in the electric two-wheeled vehicle has been modified based on the reading result of the passive radio frequency identification reader.

[0100] It should be noted that the battery management module can not only perform the above-mentioned battery management method for electric two-wheeled vehicles, but also perform multiple functions, including temperature acquisition, total voltage acquisition, current acquisition and charging protection. Temperature acquisition is used to monitor the temperature of the battery to prevent overheating or overcooling, both of which may have a negative impact on battery performance and safety. Total voltage acquisition is used to measure the total voltage of the entire battery pack to ensure that the battery operates within the correct voltage range. Current acquisition is used to monitor the charge and discharge current of the battery to ensure that the current is within a safe range. Charging protection is used to prevent the battery voltage from exceeding its maximum safe voltage to avoid battery damage or danger.

[0101] In addition, the battery management module can operate normally under low-power supply support. For example, the battery management system of the lead-acid battery can minimize its own energy consumption while providing comprehensive battery management and protection functions, so it can operate normally under low-power supply support.

[0102] Furthermore, since the passive RFID reader in the battery management module needs to communicate with the passive RFID tag on the battery cell group, the battery management module may further include a RF antenna interface to achieve communication with the passive RFID tag.

[0103] In some embodiments, the battery management module may also write battery status information of the battery pack into a passive radio frequency identification tag on the battery pack, wherein the battery status information includes at least one of the number of cycles, health status, and activation time.

[0104] In some embodiments, the battery management module may also encrypt the reading channel between the passive RFID reader and the passive RFID tag.

[0105] In some embodiments, the passive RFID reader includes an antenna and a processing module. The antenna is used to communicate with the passive RFID tag on the battery pack; the processing module is used to obtain the identity information of the battery pack according to the communication signal. The antenna and the processing module can obtain the identity information of the battery pack that is not stored in the RFID tag.

[0106] In some embodiments, the processing module reuses the controller, thereby reducing space and saving hardware costs.

[0107] In some embodiments, the processing module includes an encryption module, so that the reading channel between the passive RFID reader and the passive RFID tag can be encrypted to improve the security of transmitted data.

[0108] The present application also provides an electric two-wheeled vehicle, comprising a communication module, at least one battery cell group, and the above-mentioned battery management module, each battery cell group is provided with a passive radio frequency identification tag, and the passive radio frequency identification tag is used to communicate with a passive radio frequency identification reader in the battery management module; in the case of multiple battery cell groups, each battery cell group is provided with its own housing; each battery cell group is electrically connected to the battery management module, and the battery management module is connected to the communication module; the communication module is used to directly or indirectly connect to a server.

[0109] In some embodiments, each cell group is a lead-acid battery cell group, thereby solving the problem that current lead-acid battery cell groups are difficult to effectively monitor modification and third-party battery installation, and difficult to effectively trace the original factory batteries.

[0110] The present application also provides a handheld card reader device, which reuses the passive radio frequency identification reader of the battery management module.

[0111] The handheld card reader device provided in the embodiment of the present application can scan the passive radio frequency identification tag and obtain the information in the passive radio frequency identification tag when the passive device identification reader in the battery management module cannot locate the problem battery, so that the problem battery can be found according to the information in the passive device identification tag obtained by the handheld card reader device, so as to replace the problem battery after sales. For example, the problem battery can be found manually.

[0112] In some embodiments, the handheld card reader device includes a networking module for obtaining record information of the battery cell from a server.
