[0060] Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, which include various details of the embodiments of the present disclosure to assist in understanding, which should be considered in a descriptive sense only. It will thus be recognized by those of ordinary skill that various changes and modifications can be made to the embodiments described and illustrated herein without departing from the scope and spirit of the present disclosure. Also, for the purpose of clarity and the brevity, the description below omits the description of well-known functions and structures.

[0061] The present disclosure provides a battery encryption method, device, equipment, system, readable storage medium and product, which is applied to intelligent transportation in the field of data processing, so as to ensure the safety of new energy vehicle battery, control the battery to stop power supply when the verification fails based on the encryption system, and avoid the battery theft.

[0062] With the rapid development of new energy vehicles, the traditional vehicle anti-theft technology cannot completely cover the application scenarios of new energy vehicles. Compared with the engine of traditional fuel vehicles, the battery of new energy vehicles has higher integration and is more easily disassembled and reused.

[0063] The current market for battery theft prevention technology mainly presents the form of warning the thief through the vehicle external alarm sound, vehicle locking cannot drive and other ways. However, using the above method to prevent battery theft cannot output warning sound in the case of damaging the camera, damaging the sensor or damaging the loudspeaker of the thief. In addition, if the thief directly removes the battery, the loudspeaker has no power support, and the alarm will not be triggered, and the vehicle battery protection cannot be effectively performed.

[0064] In the process of solving the above technical problems, the inventor found through research that in order to be able to realize the protection of the new energy vehicle battery, a battery encryption system can be set. In the battery decryption system, the control module and the battery module can be used for encryption verification to ensure that the vehicle and the battery are matched one by one. Therefore, even if the battery is stolen, the battery cannot be used on other vehicles. The transaction of the battery on the market is solved from the root, and the battery theft is avoided.

[0065] Optionally, the public key, the private key and the target key can be pre-stored in the battery module. When the vehicle starts, the control system can send a handshake signal to the battery module. After verification, the battery module sends the public key to the control module. The control module encrypts the target key based on the public key and sends it to the battery module. After the target key is verified, the battery module can perform heartbeat verification with the control module. Based on the verification result, power supply is performed. When the verification fails, the power supply operation is stopped to ensure that the vehicle and the battery are matched one by one.

[0066] In order to enable the reader to understand the implementation principle of the present disclosure more deeply, the following Figures 1-14 The embodiment of the present disclosure is further refined.

[0067] Figure 1 The system architecture based on the present disclosure is shown in Figure 1 The system architecture based on the present disclosure includes a battery module 11 and a control module 12. The battery module 11 and the control module 12 are in communication connection. The battery module 11 pre-stores a preset public key 13, a private key 14 and a target key 15. The control module 12 pre-stores the target key 15.

[0068] Based on the above system architecture, when the vehicle starts, the control module 12 can send a power supply request signal to the battery module 11. In response to the power supply request signal, the battery module 11 sends a preset public key 13 to the control module 12. The control module 12 can perform an encryption operation on the target key 15 based on the preset public key 13, and feed back the encrypted data to the battery module 11. The battery module 11 can perform a decryption operation on the encrypted data, and perform a verification operation on the target key sent by the control module 12 based on the pre-stored target key 15. After verification, the battery module 11 can perform a heartbeat verification operation with the control module 12, and determine whether to continue the power supply operation based on the verification result.

[0069] Figure 2 The flowchart of the battery encryption method provided by the embodiments of the present disclosure is applied to a battery module, as shown in the figure, the method comprises: Figure 2

[0070] Step 201, in response to the power supply request signal sent by the preset control module, a preset public key is sent to the control module.

[0071] Step 202, obtain the encrypted data sent by the control module, the encrypted data is obtained by encrypting the preset target key based on the preset public key by the control module.

[0072] Step 203, the encrypted data is decrypted by the private key corresponding to the preset public key to obtain the target key, and the legality verification operation is performed on the target key.

[0073] Step 204, in response to the target key passing the legality verification, the heartbeat verification operation is performed between the target key and the control module based on the target key, and the power supply operation is performed based on the verification result of the heartbeat verification operation.

[0074] The execution subject of the embodiment is a battery encryption device. The battery encryption device can be coupled in the battery module.

[0075] In the embodiment, the battery module is in communication connection with the control module. The preset public key and the private key corresponding to the preset public key can be pre-set in the battery module. In addition, the target key can also be pre-set in the battery module and the control module. The target key can be any kind of preset key, or the target key can be the vin code of the current vehicle.

[0076] Among them, the battery module can be arranged in the battery installed in the new energy vehicle. The control module can be arranged in the new energy vehicle.

[0077] ​Optionally, in order to realize the battery encryption, when the vehicle starts, the control module can initiate a power supply request signal to the battery module, which can be a handshake signal, or can be any signal for requesting power supply, and the present disclosure does not limit it.

[0078] Further, in response to the power supply request signal, the battery module can send the preset public key to the control module.

[0079] It should be noted that when the vehicle starts for the first time, the battery module can send the preset public key to the control module. The control module can store the preset public key, so that the battery module can no longer send the preset public key to the control module. Alternatively, the control module can also not store the preset public key, and the battery module can send the preset public key to the control module every time the vehicle starts. The present disclosure does not limit it.

[0080] Further, in order to ensure the security of subsequent data interaction, after obtaining the preset public key, the control module can encrypt the pre-stored target key based on the preset public key to obtain encrypted data, and return the encrypted data to the battery module.

[0081] After the battery module obtains the encrypted data, the battery module can decrypt the encrypted data based on the private key corresponding to the preset public key to obtain the target key sent by the control module.

[0082] Optionally, in order to ensure the one-to-one relationship between the vehicle and the battery, after obtaining the target key, the target key can be further verified for legality to determine whether the control module is the control module matched with the battery, that is, it can be determined whether the vehicle currently installed with the battery is matched with the battery.

[0083] Further, after the legality verification of the target key is passed, the battery module can perform the power supply operation. Further, the control module and the battery module can also perform bidirectional heartbeat verification operation. In the verification process, the control module and the battery module can generate heartbeat packets and transmit them to the battery module and the control module respectively according to the preset transmission parameters. Therefore, the control module and the battery module can perform heartbeat verification based on the transmission frequency, decryption result and other information to determine whether to continue power supply.

[0084] In order to ensure the data security in the heartbeat verification process, the transmitted heartbeat packet can be encrypted by the target key.

[0085] The battery encryption method provided in the embodiment can ensure the one-to-one relationship between the vehicle and the battery, and can stop the power supply operation when the battery is installed in a vehicle that does not match, that is, the battery cannot be used after being stolen, thereby avoiding battery theft from the root.

[0086] Optionally, on the basis of any of the above embodiments, step 201 comprises:

[0087] In response to the handshake verification request triggered by the control module, performing a three-way handshake verification operation with the control module.

[0088] In response to the three-way handshake verification passing, sending a preset public key to the control module.

[0089] In the embodiment, the power supply request signal can be a handshake verification request.

[0090] Correspondingly, after the battery module obtains the handshake verification request sent by the control module, the battery module can perform a three-way handshake verification operation with the control module. After the three-way handshake verification passes, the battery module sends a preset public key to the control module.

[0091] The handshake verification operation between the battery module and the control module can be implemented by using an existing handshake verification method, and the present disclosure does not limit this.

[0092] The battery encryption method provided in the embodiment can effectively ensure the data security of the preset public key by sending the preset public key to the control module after the three-way handshake verification passes.

[0093] Optionally, on the basis of any of the above embodiments, step 203 comprises:

[0094] Comparing the target key sent by the control module with a pre-stored key.

[0095] If the target key is consistent with the pre-stored key, it is determined that the target key passes the legality verification.

[0096] If the target key is inconsistent with the pre-stored key, it is determined that the target key does not pass the legality verification, and the battery module is controlled not to perform a power transmission operation.

[0097] In the embodiment, in order to ensure the correspondence between the battery module and the control module, after obtaining the encrypted data sent by the control module, the target key sent by the control module can be compared with a pre-stored key.

[0098] If the target key is consistent with the pre-stored key, it indicates that the control module corresponds to the battery module, and thus it can be determined that the target key passes the legality check. Otherwise, it indicates that the control module does not match the battery module, that is, the battery does not match the vehicle in which the battery is installed. In order to ensure the safety of the battery, it can be determined that the target key fails the legality check, and the battery module is controlled not to perform the power transmission operation.

[0099] The battery encryption method provided in this embodiment can ensure the one-to-one relationship between the vehicle and the battery by performing the legality check on the target key. When the battery is installed in a mismatched vehicle, the power supply operation can be stopped, that is, the stolen battery cannot be used, and thus the battery theft is avoided from the root.

[0100] Figure 3 The flowchart of the battery encryption method provided in another embodiment of the present disclosure is shown in FIG. 4, which is based on any of the above embodiments. As shown in FIG. 4, step 204 includes: Figure 3

[0101] Step 301: obtaining at least one heartbeat packet sent by the control module, the heartbeat packet being obtained by encrypting a preset parameter based on the target key by the control module.

[0102] Step 302: performing a decryption operation on the at least one heartbeat packet based on the target key to obtain a decryption result.

[0103] Step 303: performing a heartbeat check operation according to the decryption result to obtain a check result.

[0104] Step 304: performing a power transmission operation in response to the check result being a check success.

[0105] Step 305: stopping the power transmission operation in response to the check result being a check failure.

[0106] In this embodiment, the battery module and the control module can perform a bidirectional heartbeat check operation. The control module can generate a heartbeat packet and transmit it to the battery module according to a preset transmission parameter, so that the battery module performs a heartbeat check operation on the control module.

[0107] Optionally, after obtaining the at least one heartbeat packet sent by the control module, since the heartbeat packet is obtained by encrypting a preset parameter based on the target key by the control module. Therefore, the heartbeat packet can be decrypted based on the pre-stored target in the battery module to obtain a decryption result. Thus, the heartbeat check operation can be performed based on the decryption result, or based on whether the pre-stored target key can be decrypted at present.

[0108] ​Optionally, if the verification passes, it is indicated that the battery module matches the control module, and power transmission can be performed. Otherwise, it is indicated that the battery module does not match the control module, and the battery may be stolen, so the power supply operation can be stopped to ensure the safety of the battery.

[0109] The battery encryption method provided in the embodiment can determine whether to continue power supply based on the transmission frequency and the decryption result. When the verification fails, the power supply is stopped, and the safety of the battery is further ensured.

[0110] Further, based on any of the above embodiments, step 303 comprises:

[0111] If the decryption result is decryption failure, it is determined that the verification result is verification failure.

[0112] If the decryption result is decryption success, the preset parameter obtained by decryption is compared with the heartbeat parameter generated based on the preset heartbeat information generation parameter.

[0113] If the preset parameter matches the heartbeat parameter, it is determined that the verification result is verification success.

[0114] If the preset parameter does not match the heartbeat parameter, it is determined that the verification result is verification failure.

[0115] In the embodiment, after the heartbeat packet is decrypted based on the target key pre-stored in the battery module to obtain a decryption result, the heartbeat verification operation can be performed based on the decryption result or based on whether the target key pre-stored in the battery module can be used to perform decryption at present.

[0116] Optionally, if the decryption result is decryption failure, it is indicated that the target key pre-stored in the battery module does not match the target key pre-stored in the control module, and it is determined that the verification result is verification failure.

[0117] If the decryption result is decryption success, the preset parameter obtained by decryption is compared with the heartbeat parameter generated based on the preset heartbeat information generation parameter. If the preset parameter matches the heartbeat parameter, it is determined that the verification result is verification success. If the preset parameter does not match the heartbeat parameter, it is determined that the verification result is verification failure.

[0118] The battery encryption method provided in the embodiment can determine whether to continue power supply based on the transmission frequency and the decryption result. When the verification fails, the power supply is stopped, and the safety of the battery is further ensured.

[0119] Figure 4A flowchart of a battery encryption method provided for another embodiment of the present disclosure is shown in FIG. 4. Based on any of the above embodiments, step 204 includes: Figure 4

[0120] Step 401: generating at least one heartbeat parameter according to a preset heartbeat information generation parameter.

[0121] Step 402: performing an encryption operation on each heartbeat parameter based on the target key to obtain at least one to-be-transmitted heartbeat packet.

[0122] Step 403: sequentially transmitting each to-be-transmitted heartbeat packet to the control module according to a preset time interval, so that the control module performs a heartbeat check operation on the battery module.

[0123] In this embodiment, the battery module and the control module can perform a bidirectional heartbeat check operation. The battery module can generate a to-be-transmitted heartbeat packet and transmit the to-be-transmitted heartbeat packet to the control module according to a preset transmission parameter, so that the control module performs a heartbeat check operation on the battery module.

[0124] Optionally, at least one preset parameter can be generated according to a preset heartbeat information generation parameter. The preset parameter can be a blank field, or can be a preset field, or the preset parameter can be an incrementing number each time, and the present disclosure does not limit this.

[0125] The battery module and the control module can both generate a preset parameter based on the heartbeat information generation parameter. Therefore, they can hold the same preset parameter for subsequent heartbeat check operations.

[0126] Further, in order to ensure data security and implement heartbeat check, for each preset parameter, a target key is used to perform an encryption operation on the preset parameter to obtain at least one to-be-transmitted heartbeat packet. Each to-be-transmitted heartbeat packet is sequentially transmitted to the control module according to a preset time interval, so that the control module performs a heartbeat check operation on the battery module.

[0127] Optionally, by sending the to-be-transmitted heartbeat packet according to the preset time interval, the control module can determine that the heartbeat check fails when the adjacent heartbeat packet receiving time interval does not match the preset time interval.

[0128] The battery encryption method provided in this embodiment can further ensure the security of the battery by performing a bidirectional heartbeat check operation between the battery module and the control module.

[0129] Figure 5 A flowchart of a battery encryption method provided for another embodiment of the present disclosure is shown in FIG. 4. Based on any of the above embodiments, step 204 includes: ​

[0133] Step 504, according to the target key, performing a heartbeat check operation with the battery module, and based on the check result, performing a power transmission operation, wherein the heartbeat check operation is performed after the target key is determined to pass the legality check by the battery module.

[0134] The execution subject of the embodiment is a battery encryption device. The battery encryption device can be coupled in the control module.

[0135] In the embodiment, the battery module is in communication connection with the control module. The battery module can be pre-provided with a preset public key and a private key corresponding to the preset public key. In addition, the battery module and the control module can also be pre-provided with a target key.

[0136] Optionally, in order to realize battery encryption, when the vehicle starts, the control module can initiate a power supply request signal to the battery module, which can be a handshake signal, or any signal used to request power supply, which is not limited by the present disclosure.

[0137] Further, after obtaining the power supply request signal, the battery module can send the preset public key to the control module.

[0138] It should be noted that when the vehicle starts for the first time, the battery module can send the preset public key to the control module. After obtaining the target key, the control module can store the preset public key, so that the battery module can no longer send the preset public key to the control module. Alternatively, the control module can also not store the preset public key, and the battery module can send the preset public key to the control module every time the vehicle starts. The present disclosure does not make any limitation.

[0139] Further, in order to ensure the security of subsequent data interaction, after obtaining the preset public key, the control module can perform encryption operation on the pre-stored target key based on the preset public key to obtain encrypted data, and return the encrypted data to the battery module.

[0140] After obtaining the encrypted data, the battery module can decrypt the encrypted data based on the private key corresponding to the preset public key to obtain the target key sent by the control module.

[0142] Further, after the legality verification of the target key is passed, the battery module can perform a power supply operation. Further, the control module can perform a two-way heartbeat check operation with the battery module. In the check process, the control module and the battery module can each generate a heartbeat packet and transmit it to the battery module and the control module respectively according to preset transmission parameters. Therefore, the control module and the battery module can perform a heartbeat check based on transmission frequency, decryption result and other information to determine whether to continue power supply.

[0143] In order to ensure the safety of data in the heartbeat check process, the transmitted heartbeat packet can be encrypted by the target key.

[0149] Step 603, each heartbeat packet is transmitted to the battery module in turn according to a preset time interval, so that the battery module performs a heartbeat check operation on the control module.

[0150] In the embodiment, the battery module and the control module can perform a bidirectional heartbeat verification operation. The control module can generate a heartbeat packet and transmit it to the battery module according to preset transmission parameters, so that the battery module performs a heartbeat verification operation on the control module.

[0151] Optionally, at least one preset parameter can be generated according to a preset heartbeat information generation parameter. The preset parameter can be a blank field, or can be a preset field, or the preset parameter can be an incrementing number, and the present disclosure does not limit this.

[0152] Further, in order to ensure data security and implement heartbeat verification, for each preset parameter, the target key is used to perform an encryption operation on the preset parameter to obtain at least one heartbeat packet. Each heartbeat packet is transmitted to the battery module in turn according to a preset time interval, so that the battery module performs a heartbeat verification operation on the control module.

[0153] Optionally, by transmitting the heartbeat packet according to the preset time interval, the battery module can determine that the heartbeat verification fails when the adjacent heartbeat packet receiving time interval does not match the preset time interval.

[0154] The battery encryption method provided in the embodiment can determine whether to continue power supply based on the transmission frequency, decryption result, and other verification results by performing an encryption operation on the heartbeat packet based on the target key and performing a heartbeat verification based on the encrypted heartbeat packet. When the verification fails, the power supply is stopped, further ensuring the safety of the battery.

[0155] Figure 7 The flowchart of the battery encryption method provided in another embodiment of the present disclosure is based on any of the above embodiments, as shown in Figure 7 The step 504 includes:

[0156] Step 701, obtaining at least one to-be-transmitted heartbeat packet sent by the battery module, the to-be-transmitted heartbeat packet being obtained by encrypting a heartbeat parameter based on the target key by the battery module.

[0157] Step 702, performing a decryption operation on the at least one to-be-transmitted heartbeat packet by the target key to obtain a decryption result.

[0158] Step 703, comparing the decryption result with a preset parameter generated based on a preset heartbeat information generation parameter to obtain a verification result.

[0159] Step 704, in response to the verification result being a verification pass, performing a power transmission operation.

[0160] Step 705, in response to the check result being a check failure, the communication connection with the battery module is disconnected.

[0161] In the embodiment, the battery module and the control module can perform a bidirectional heartbeat check operation.

[0162] Optionally, the control module can also obtain at least one to-be-transmitted heartbeat packet sent by the battery module, the to-be-transmitted heartbeat packet being obtained by encrypting the heartbeat parameter based on the target key.

[0163] Further, after obtaining the to-be-transmitted heartbeat packet, the to-be-transmitted heartbeat packet can be decrypted based on the target key to obtain a decryption result. Thus, the heartbeat check operation can be implemented based on the decryption result or whether the pre-stored target key can be currently used for decryption.

[0164] Optionally, if the check passes, it indicates that the battery module and the control module match, and at this time, the power transmission operation can be performed. Otherwise, it indicates that the battery module and the control module do not match, and at this time, the battery may be at risk of being stolen, so the communication connection with the battery module can be disconnected to ensure the safety of the battery.

[0165] The battery encryption method provided in the embodiment can encrypt the heartbeat packet based on the target key, perform the heartbeat check based on the encrypted heartbeat packet, and determine whether to continue to supply power based on the check result such as the transmission frequency and the decryption result. When the check fails, the communication connection with the battery module is disconnected, further ensuring the safety of the battery.

[0166] Further, on the basis of any of the above embodiments, step 703 comprises:

[0167] If the decryption result is consistent with the preset parameter, it is determined that the check result is a check pass.

[0168] If the decryption result is inconsistent with the preset parameter, or the decryption result is a decryption failure, it is determined that the check result is a check failure.

[0169] In the embodiment, after obtaining the to-be-transmitted heartbeat packet sent by the battery module, the to-be-transmitted heartbeat packet can be decrypted based on the target key. Thus, the heartbeat check operation can be implemented based on the decryption result or whether the pre-stored target key can be currently used for decryption.

[0170] Optionally, if the decryption result is consistent with the preset parameter, it is determined that the check result is a check pass.

[0171] Conversely, if the decryption result is inconsistent with the preset parameter, or the decryption result is decryption failure, it is determined that the check result is check failure.

[0172] The battery encryption method provided in the embodiment determines whether to continue power supply based on the check result of the transmission frequency and the decryption result in the heartbeat check process. When the check fails, the communication connection with the battery module is disconnected, further ensuring the safety of the battery.

[0173] Figure 8 The flowchart of the battery encryption method provided in the embodiment of the present disclosure is applied to a battery encryption system, which includes a battery module and a control module, and the battery module is in communication connection with the control module. As shown in Figure 8 The method includes the following steps.

[0174] Step 801, in response to the start of the vehicle, the control module sends a power supply request signal to the preset battery module.

[0175] Step 802, the battery module acquires the power supply request signal sent by the control module, and sends a preset public key to the control module.

[0176] Step 803, the control module acquires the preset public key sent by the battery module, performs encryption operation on the preset target key based on the preset public key, generates encrypted data, and sends the encrypted data to the battery module.

[0177] Step 804, the battery module decrypts the encrypted data by using the private key corresponding to the preset public key, acquires the target key, and performs legality check operation on the target key.

[0178] Step 805, in response to the target key passing the legality check, the battery module and the control module perform heartbeat check operation based on the target key, and perform power supply operation based on the check result of the heartbeat check operation.

[0179] The execution subject of the embodiment is a battery encryption device, which can be coupled with a battery encryption system. The battery encryption system includes a battery module and a control module, and the battery module is in communication connection with the control module. The battery module can prestore a preset public key, a private key and a target key. The control module prestores the target key.

[0180] Based on the above system architecture, in response to the start of the vehicle, the control module sends a power supply request signal to the preset battery module. The power supply request signal can be a handshake signal, or it can be any kind of signal for requesting power supply, which is not limited in the present disclosure.

[0181] Further, the battery module can obtain the power supply request signal sent by the control module, and send a preset public key to the control module. After obtaining the preset public key, the control module can perform a storage operation on the preset public key, so that the battery module no longer needs to perform a sending operation of the preset public key to the control module in the future when the vehicle starts. Alternatively, the control module can also not store the preset public key, and the battery module can send the preset public key to the control module every time the vehicle starts. The present disclosure does not limit this.

[0182] The control module obtains the preset public key sent by the battery module, performs an encryption operation on the preset target key based on the preset public key, generates encrypted data, and sends the encrypted data to the battery module. The battery module decrypts the encrypted data by using a private key corresponding to the preset public key to obtain the target key. In order to ensure the one-to-one relationship between the vehicle and the battery, after obtaining the target key, a legality verification operation can also be performed on the target key to determine whether the control module is a control module matched with the battery, that is, it can be determined whether the vehicle currently installed with the battery is matched with the battery.

[0183] In response to the target key passing the legality verification, the battery module and the control module perform a heartbeat verification operation based on the target key, and perform a power supply operation based on the verification result of the heartbeat verification operation. Therefore, when the verification fails, the power supply is stopped, further ensuring the safety of the battery.

[0184] The battery encryption method provided by the embodiment can ensure the one-to-one relationship between the vehicle and the battery by setting a battery encryption system, transmitting the target key in the battery encryption system by using an asymmetric encryption mode, and performing a power supply operation after the legality verification of the target key passes, so that when the battery is installed in a vehicle that does not match, the power supply operation can be stopped, that is, the battery cannot be used after being stolen, so that the theft of the battery is avoided from the root. In addition, in the power supply process, the heartbeat packet can be encrypted by using the target key to perform a heartbeat verification operation, and the power supply is stopped when the verification fails, further ensuring the safety of the battery.

[0187] Step 902: Update the current preset public key of the control module to the updated public key according to the updated data, and update the target key currently stored in the control module to the updated key according to the updated data.

[0188] Step 903: Update the current preset public key and private key of the battery module to the updated public key and updated private key according to the updated data, and switch the target key in the battery module to the updated key according to the updated data.

[0189] In this embodiment, when a new energy vehicle replaces its battery, in order to ensure battery safety, the user can update the preset public key, private key, and target key stored in the battery module, as well as update the target key in the control module.

[0190] Optionally, users can set update data in a pre-installed application on their terminal device. This update data includes an updated private key, an updated public key, and an updated private key. After completing the setup, the update data can be uploaded to a cloud server.

[0191] Accordingly, the application software installed in the new energy vehicle can obtain the updated data from the cloud server. Based on the updated data, the control module's current preset public key is updated to an updated public key, and the target key currently stored in the control module is updated to an updated key. Based on the updated data, the battery module's current preset public and private keys are updated to updated public and private keys, and the target key in the battery module is switched to the updated key.

[0192] This allows the battery module and control module to perform subsequent key verification and heartbeat verification operations based on the updated data, and then supply power after successful verification.
