Technical Field

[0002] In the context of encrypting the battery of terminal devices, there is currently no way to verify and identify the use of official battery protection boards and third-party battery cells. However, since third-party battery cells do not meet the performance requirements of official batteries, if the charging strategy of official battery cells is used without identifying the third-party battery cells, there is a huge risk of serious safety accidents such as fires and combustion, which also poses a great threat to the safety of users. Summary of the Invention
[0003] To overcome the problems existing in related technologies, this disclosure provides a battery verification method and a battery.
[0004] According to a first aspect of the present disclosure, a battery verification method is provided, comprising: obtaining a cell identification code corresponding to a target cell in a current device; the cell is provided with a communication device, and the cell identification code is pre-configured in the communication device; obtaining protection board information corresponding to a battery protection board in the current device; and verifying the target cell and the battery protection board based on the cell identification code and the protection board information to obtain a battery verification result.
[0005] In some embodiments, obtaining the cell identification code corresponding to the target cell in the current device includes: obtaining the cell identification code corresponding to the target cell through a first wireless connection between the current device and the communication device.
[0006] In some embodiments, obtaining the cell identification code corresponding to the target cell in the current device includes: obtaining the cell identification code corresponding to the target cell by obtaining a wired connection between the current device and the battery protection board; wherein the cell identification code is an identification code that the target cell has pre-sent to the battery protection board via a second wireless connection, and the second wireless connection is a wireless connection between the battery protection board and the communication device.
[0007] In some embodiments, obtaining the cell identification code corresponding to the target cell in the current device includes: triggering the operation of obtaining the cell identification code corresponding to the target cell in the current device when it is detected that the current device is connected to a power supply device and starts charging.
[0008] In some embodiments, the step of verifying the target battery cell and the battery protection board based on the cell identification code and the protection board information to obtain a battery verification result includes: obtaining a preset cell identification code and preset protection board information, wherein the preset cell identification code and the preset protection board information are information stored in the current device when the battery is first installed; comparing whether the cell identification code and the preset cell identification code, and the protection board information and the preset protection board information are consistent; if they are all consistent, then the battery verification result is that the current battery is a first-type battery.
[0009] In some embodiments, after verifying the target cell and the battery protection board based on the cell identification code and the protection board information to obtain the battery verification result, the method further includes: determining a charging strategy based on the battery verification result.
[0010] In some embodiments, the battery protection board is provided with an encryption chip, which is used to prevent the protection board information of the battery protection board and the cell identification code of the battery cell from being copied.
[0011] In some embodiments, the encryption chip is an ECC encryption authentication chip or a SHA encryption authentication chip.
[0012] According to a second aspect of the present disclosure, a battery is provided, including a battery cell, the battery cell being provided with a communication device, the communication device being configured with a battery cell identification code; a battery protection board electrically connected to the battery cell, and the battery protection board being provided with an encryption chip; and a housing covering the battery cell and the battery protection board.
[0013] In some embodiments, the communication device is configured with a wireless communication device, which includes one or more of Bluetooth, Zigbee, or UWB.
[0014] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:
[0015] First, by placing the communication device on the battery cell and storing the cell identification code in the communication device, the cell becomes an independent product that can communicate with the battery protection board and terminal equipment simultaneously, thereby avoiding third-party batteries.
[0016] Secondly, in addition to the battery protection board communicating with the battery cell and serving as the battery cell identification code, since the battery cell communicates directly with the terminal device, the terminal device can directly verify the battery cell identification code. Therefore, the terminal device can perform dual verification of the battery protection board and the battery cell, avoiding the drawback of the terminal device only verifying the battery protection board and not being able to verify the combination of the official battery protection board and the third-party battery.
[0017] Finally, the cell identification code is stored in the communication device, rather than printed on the surface or other structures of the cell. This allows the cell identification code to be directly and wirelessly transmitted to the battery protection board or terminal device, and it is also not easily worn away, thus avoiding situations where it is difficult to identify.
[0018] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description
[0019] The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments consistent with this disclosure and, together with the description, serve to explain the principles of this disclosure.

[0021] Figure 2 This is a schematic diagram illustrating a battery and terminal device assembly according to an exemplary embodiment.
[0022] Figure 3 This is a block diagram illustrating an apparatus according to an exemplary embodiment. Detailed Implementation
[0023] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.
[0024] In the context of encrypting the battery of terminal devices, there is currently no way to verify and identify the use of official battery protection boards and third-party battery cells. However, since third-party battery cells do not meet the performance requirements of official batteries, if the charging strategy of official battery cells is used without identifying the third-party battery cells, there is a huge risk of serious safety accidents such as fires and combustion, which also poses a great threat to the safety of users.
[0025] To address the aforementioned technical problems, according to embodiments of this disclosure, a battery 10 verification method is provided. The battery 10 is used in a terminal device 100 and provides power to the terminal device 100. The terminal device 100 may be a mobile phone, computer, digital broadcasting terminal, messaging device, game console, tablet device, medical device, fitness device, personal digital assistant, translator, and wearable devices such as watches and bracelets. In this disclosure, a mobile phone is used as the terminal device 100 for description.
[0026] like Figure 1 As shown, the battery verification method includes the following steps: S11, obtaining the cell identification code corresponding to the target cell 11 in the current device; the cell 11 is equipped with a communication device, and the cell identification code is pre-configured in the communication device; S12, obtaining the protection board information corresponding to the battery protection board 12 in the current device; S13, verifying the target cell 11 and the battery protection board 12 based on the cell identification code and the protection board information, and obtaining the battery 10 verification result.
[0027] This disclosure installs a communication device pre-configured with a cell identification code on the cell 11 of the battery 10, enabling the cell 11 to communicate not only with the battery protection board 12 but also directly with the terminal device. This allows the terminal device to perform dual verification of the battery protection board 12 and the cell 11, avoiding the drawback of the terminal device only verifying the battery protection board 12 and being unable to verify the combination of the official battery protection board 12 and the third-party battery 10.
[0028] In the first embodiment, obtaining the cell identification code corresponding to the target cell 11 in the current device includes: obtaining the cell identification code corresponding to the target cell 11 through the first wireless connection between the current device and the communication device.
[0029] The current device directly connects wirelessly to the communication device of the battery cell 11 to obtain the battery cell identification code of the battery cell 11. It can directly verify the battery cell 11 without going through the battery protection board 12, thus avoiding the situation where the official battery protection board 12 is combined with the third-party battery cell 11.
[0030] In the second embodiment, obtaining the cell identification code corresponding to the target cell 11 in the current device includes: obtaining the cell identification code corresponding to the target cell 11 by obtaining the wired connection between the current device and the battery protection board 12; wherein, the cell identification code is the identification code that the target cell 11 has sent to the battery protection board 12 in advance through the second wireless connection, and the second wireless connection is the wireless connection between the battery protection board 12 and the communication device.
[0031] The battery cell 11 and the battery protection board 12 are connected via a second wireless connection. The battery cell identification code of the battery cell 11 is first transmitted to the battery protection board 12 through the communication device and stored by the battery protection board 12. Then, the battery protection board 12 transmits it to the current device through a wired connection.
[0032] In some embodiments, obtaining the cell identification code corresponding to the target cell 11 in the current device includes: when it is detected that the current device is connected to a power supply device and starts charging, triggering the operation of obtaining the cell identification code corresponding to the target cell 11 in the current device.
[0033] In addition, the device can trigger the process of obtaining the cell identification code corresponding to the target cell 11 within the device each time it is charged. Verification can also be performed at preset intervals, such as during the first charge within a preset time period.
[0034] In some embodiments, the target cell 11 and the battery protection board 12 are verified based on the cell identification code and protection board information to obtain the battery 10 verification result, including: obtaining a preset cell identification code and preset protection board information, which are information stored in the current device when the battery 10 is first installed; comparing whether the cell identification code and the preset cell identification code, and the protection board information and the preset protection board information are consistent; if they are all consistent, the battery 10 verification result is that the current battery 10 is a first type of battery 10.
[0035] When the battery 10 is installed for the first time, the battery protection board 12 stores the cell identification code of the original official battery cell 11. The current device stores the cell identification code of the battery cell 11 and the protection board information of the battery protection board 12.
[0036] In addition, the first type of battery 10 is the official battery 10. The official battery 10 can be the original battery 10 of the device (the official battery protection board 12 and the original official battery cell 11), or the official battery 10 can be a combination of the official battery protection board 12 and other official battery cells 11.
[0037] In some embodiments, after verifying the target cell 11 and the battery protection board 12 based on the cell identification code and protection board information to obtain the verification result of the battery 10, the method further includes: determining a charging strategy based on the verification result of the battery 10.
[0038] If it is an official Battery 10, charge it with a higher current; if it is not an official Battery 10, charge it with a lower current to avoid safety issues.
[0039] In some embodiments, the battery protection board 12 is provided with an encryption chip for storing the cell identification code of the battery cell 11 and preventing the protection board information of the battery protection board 12 and the cell identification code of the battery cell 11 from being copied.
[0040] Based on the same inventive concept, this disclosure also provides a battery for use in terminal device 100.
[0041] Furthermore, Figure 2 This is a schematic diagram illustrating the assembly of a battery and a terminal device 100 according to an exemplary embodiment. Figure 2As shown, the battery 10 includes: a battery cell 11, the battery cell 11 is provided with a communication device, the communication device is configured with a battery cell identification code; a battery protection board 12 is electrically connected to the battery cell 11, and the battery protection board 12 is provided with an encryption chip; and a housing, which is wrapped around the battery cell 11 and the battery protection board 12.
[0042] Specifically, the battery 10 includes a cell 11, a battery protection board 12, and a casing (not shown in the figure).
[0043] Among them, cell 11 refers to a single electrochemical cell 11 containing positive and negative electrodes, which generally cannot be used directly. The quality of cell 11 directly determines the quality of rechargeable battery 10. Cell 11 is divided into three types: aluminum-cased cell, pouch cell (also known as "polymer cell"), and cylindrical cell. Mobile phone batteries 10 usually use aluminum-cased cells, Bluetooth and other digital products mostly use pouch cells, and laptop batteries use a series and parallel combination of cylindrical cells.
[0044] The battery protection board 12 is electrically connected to the battery cell 11 and is an integrated battery protection board 12 that protects the rechargeable lithium battery 10. The battery protection board 12 is used to prevent damage to the battery 10 and extend its lifespan. The battery protection board 12 is similar to a fuse or circuit breaker in household appliances. Because the materials of the lithium battery 10 itself dictate that it cannot be overcharged, over-discharged, over-currented, short-circuited, or charged and discharged at excessively high temperatures, the battery protection board 12 provides the most stable and effective protection measures in the event of extreme problems with the battery 10, thereby preventing accidents.
[0045] The battery protection board 12 is electrically connected to the terminal device 100. When the battery 10 is installed in the terminal device 100, the terminal device 100 identifies and binds the battery protection board 12. The terminal device 100 can identify whether the battery 10 is an original battery 10 or an official battery 10 by identifying the battery protection board 12.
[0046] If the battery is identified as a non-original or non-official battery 10, the terminal device 100 may prevent the terminal device 100 from starting up, or the terminal device 100 may adopt a non-official battery 10 charging strategy, such as limiting the charging current or voltage, so that the third-party battery 10 cannot achieve fast charging and other functions. This avoids the use of the same charging strategy as the original or official battery 10, which could lead to serious safety accidents such as fire, explosion, etc., and improves the safety of users when using the third-party battery 10.
[0047] The battery protection board 12 is equipped with an encryption chip. In some embodiments, the encryption chip is an ECC encryption authentication chip or a SHA encryption authentication chip. The encryption chip on the battery protection board 12 can protect the battery cell 11 while also encrypting the battery 10, thereby protecting user security.
[0048] The Elliptic Curve Cryptography (ECC) algorithm requires minimal computation while providing high encryption strength. ECC achieves its intended high encryption strength with a relatively short key, thus offering the highest security strength per bit. The Secure Hash Algorithm (SHA) is primarily applicable to the Digital Signature Algorithm (DSA) defined in the Digital Signature Standard (DSS).
[0049] The casing surrounds the battery protection board 12 and the battery cell 11, and the casing plays a protective role. The battery protection board 12 can keep the battery protection board 12 and the battery cell 11 in a relatively stable state and prevent them from falling apart, and prevent the battery protection board 12 and the battery cell 11 from being bumped and worn by external parts, thus extending the service life of the battery 10.
[0050] Furthermore, the battery cell 11 is provided with a communication device, which is configured with a battery cell identification code. In some embodiments, the communication device is located at the end of the battery cell 11, specifically, the communication device is located inside the battery cell 11. The communication device is configured with a battery cell identification code.
[0051] By installing a communication device on the battery cell 11 of the battery 10 and storing the cell identification code in the communication device, the battery cell 11 becomes an independent product. The battery cell 11 can communicate with the battery protection board 12 through the communication device, and the battery cell 11 can also communicate directly with the terminal device 100 through the communication device.
[0052] Furthermore, to prevent the communication device from affecting the battery cell 11, a shielding device can be installed between the communication device and the battery cell 11 to avoid signal interference from the communication device to the battery cell 11.
[0053] The communication device is equipped with a cell identification code, which is a unique identifier for each cell 11. This code allows identification of the unique battery 10 corresponding to either the terminal device 100 or the battery protection board 12. The cell identification code prevents the reuse of cells 11, ensures that the terminal device 100 can recognize the official battery 10, and restricts the functionality of third-party batteries 10, thereby guaranteeing user safety.
[0054] When the battery 10, consisting of the battery cell 11 and the battery protection board 12, is first installed in the terminal device 100, since the battery cell 11 is connected to both the protection board and the terminal device 100 via a communication device, and the communication device is equipped with the battery cell identification code of the battery cell 11, either the battery protection board 12 or the terminal device 100 can recognize the battery cell identification code of the battery cell 11, thus binding the battery protection board 12 to the battery cell 11, and the terminal device 100 also binding the battery cell 11. In addition, as can be seen from the above, the terminal device 100 also recognizes the corresponding battery protection board 12 and binds the battery protection board 12.
[0055] At this time, the battery cell 11 is bound and matched with the battery protection board 12, the battery cell 11 is bound and matched with the terminal device 100, and the battery protection board 12 is bound and matched with the terminal device 100. The battery protection board 12 records and stores the cell identification code of the battery cell 11, the terminal device 100 also records the cell identification code of the battery cell 11, and the terminal device 100 also records information about the battery protection board 12.
[0056] When battery 10 is reinstalled, battery protection board 12 identifies the reinstalled battery 10 and compares it with the stored and bound cell identification code. If they match, the verification is successful. Terminal device 100 identifies and verifies the information of battery protection board 12. If they match, the verification is successful. At this time, only when terminal device 100 verifies battery protection board 12 and battery protection board 12 verifies cell 11 is the reinstalled battery 10 verified as the first-time installed battery 10; otherwise, it is considered a non-first-time installed battery 10.
[0057] As can be seen from the above, in addition to the battery protection board 12 being communicatively connected to the battery cell 11 and serving as the battery cell identification code for identifying the battery cell 11, since the battery cell 11 is directly communicatively connected to the terminal device 100, the terminal device 100 can directly verify the battery cell identification code of the battery cell 11. Therefore, the terminal device 100 can perform dual verification of the battery protection board 12 and the battery cell 11, avoiding the drawback that when the terminal device 100 only verifies the battery protection board 12, it cannot verify the combination of the official battery protection board 12 and the third-party battery 10.
[0058] Furthermore, the cell identification code is not a physical structure engraved or printed on the outer surface of the cell 11, but rather a digital symbol or code stored within the communication device. Because the cell identification code is stored in the communication device, rather than printed on the surface of the cell 11, it can be directly and wirelessly transmitted to the battery protection board 12 or the terminal device 100. It is also less prone to wear and tear, reducing the steps involved in manufacturing the cell 11 and avoiding the problem of blurred or illegible cell identification codes created by engraving or printing.
[0059] Furthermore, the communication device is equipped with a wireless communication device. In some embodiments, the wireless communication device includes one or more of Bluetooth, Zigbee, or UWB. In some embodiments, the battery cell 11 and the battery protection board 12 are wirelessly connected.
[0060] Bluetooth technology is a short-range wireless connection technology that allows you to connect to the internet without cables and access the internet wirelessly.
[0061] ZigBee, also known as Purple Bee, is a low-speed, short-range wireless network protocol. Its underlying media access layer and physical layer are based on the IEEE 802.15.4 standard. Key features include low speed, low power consumption, low cost, support for a large number of network nodes, support for various network topologies, low complexity, speed, reliability, and security.
[0062] Ultra-wideband (UWB) technology is a wireless carrier communication technology that does not use sinusoidal carriers but instead uses nanosecond-level non-sinusoidal narrow pulses to transmit data, thus occupying a very wide spectrum.
[0063] It should be noted that the above wireless communication devices are merely exemplary and are not intended to limit the scope of protection of this disclosure. In other embodiments, those skilled in the art can also use other wireless communication methods to connect the battery cell 11 to the battery protection board 12 and the terminal device 100 respectively.
[0064] In addition, the communication device can also be configured as a wired communication device, that is, the battery cell 11 is connected to the battery protection board 12 and the terminal device 100 via wired communication, which is not limited here. In this embodiment, the battery protection board 12 is connected to the terminal device 100 via wired communication. In some embodiments, the battery protection board 12 can also be connected to the terminal device 100 via wireless communication, which is also not limited here.
[0065] It is understood that the battery 10 provided in this disclosure embodiment includes hardware structures and / or software modules corresponding to each function in order to achieve the above-mentioned functions. In conjunction with the units and algorithm steps of the various examples disclosed in this disclosure embodiment, this disclosure embodiment can be implemented in hardware or a combination of hardware and computer software. Whether a certain function is executed by hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of this disclosure embodiment.
[0066] Regarding the battery 10 in the above embodiments, the specific manner in which each module performs its operation has been described in detail in the embodiments related to the battery verification method, and will not be elaborated here.
