Technical Field

[0001] The present invention relates to the technical field of electric vehicle battery replacement encryption systems, and in particular to an electric vehicle battery replacement encryption system and method. Background Art

[0002] Currently, battery-swap vehicles operate in two modes: replacement at battery-swap stations and self-charging. As battery performance declines over time, battery-swap stations replenish batteries at regular intervals to maintain operational capacity. This means that the performance and quality of batteries replaced at battery-swap stations remain at a high level.

[0003] Driven by profit, users of these self-charging vehicles may privately replace lower-quality batteries with higher-quality ones installed at battery swap stations. However, existing technologies lack monitoring and control over user battery swapping behavior, making it impossible to determine whether a user's swapping behavior complies with operational regulations. This inability to effectively prevent the theft of high-quality batteries often results in the loss of high-quality batteries at battery swap stations.

[0004] Therefore, it is necessary to propose an electric vehicle battery replacement encryption system and method to solve the above problems. Summary of the Invention

[0038] The present invention provides Figures 1 to 3 The electric vehicle battery swap encryption system shown includes: a user terminal module, including a communication unit, a biometric feature collection unit and a hardware encryption chip, user identity authentication and initiation of a battery swap request;

[0039] The communication unit realizes information interaction between the user terminal and the electric vehicle battery replacement encryption system.

[0040] Hardware encryption chips have the functions of data encryption and decryption, identity authentication and secure storage. They are mainly used to process sensitive information and ensure its privacy and integrity. Specifically, hardware encryption chips encrypt and decrypt data through built-in encryption algorithms to protect the privacy and integrity of data and prevent hackers from attacking and stealing sensitive data, thereby protecting NFC near-field communication units and biometric acquisition units.

[0041] Biometric feature collection units include iris sensors, fingerprint sensors, etc.

[0042] In specific use, identity authentication adopts a three-step verification method, including:

[0043] The first step is that the user terminal obtains the battery swap cabinet equipment certificate by scanning the code, verifies its legitimacy, and determines whether it is a real battery swap demand.

[0044] The second step is user face recognition. The biometric collection unit obtains the biometric features of the face. The biometric data is locally encrypted and uploaded to the cloud for learning and comparison with the pre-stored original data. If the comparison is successful, the battery can be replaced. If the comparison fails, the battery cannot be replaced.

[0045] The third step is to send a one-time verification code from the cloud, which is synchronized to the battery swap cabinet and the user terminal to complete the two-way signature verification. The user enters the verification code for verification and officially enters the battery swap process.

[0046] The present invention adopts a three-step identity verification method to solve the security risk of identity counterfeiting in the prior art.

[0047] The intelligent battery exchange cabinet module includes a track-type battery compartment array, a battery identification unit, and an emergency power supply unit. The track-type battery compartment array includes a horizontal slide rail and a vertical lifting mechanism, and each battery compartment is equipped with an independent temperature control sensor and an electromagnetic locking device.

[0048] A temperature control sensor is a sensor that can sense temperature and convert it into a usable output signal. It is used to monitor the temperature of the battery and ensure the stability of the battery compartment.

[0049] During specific use, a controller, a prompt device and a temperature control sensor are provided. The controller is connected between the temperature control sensor and the prompt device. The prompt device can use but is not limited to a buzzer. When the temperature control sensor detects that the battery temperature exceeds the set threshold, the prompt device is activated by the controller to remind the management personnel to deal with it in time.

[0050] The electromagnetic locking device includes an electromagnetic lock, etc., which locks each battery compartment and can only be opened after the three-step verification method to avoid battery theft. If necessary, a warning light can be set in conjunction with the electromagnetic locking device. When the electromagnetic locking device is forced to open, the warning light will flash, which can be adjusted according to specific usage.

[0051] The transfer guarantee module uses a six-axis robotic arm for automatic transfer, and the six-axis robotic arm cooperates with the battery compartment. The six-axis robotic arm is equipped with a force feedback sensor (accuracy ±0.5N) and a laser alignment device to achieve a battery grasping accuracy of ±0.2mm, ensuring the accuracy of battery replacement.

[0052] An emergency power supply unit is also provided to verify the battery identity based on the local whitelist in the event of a network outage and synchronize the operation log via the cellular network.

[0053] The battery identification unit uses a two-step verification method:

[0054] The first step is to scan the QR code on the user terminal to obtain the battery serial number and compare it with the factory information recorded in the cloud to ensure that the battery information matches;

[0055] In the second step, the battery identification unit uses an image recognition camera to detect the appearance of the battery to determine whether there are any signs of tampering, such as damaged labels and deformed shells.

[0056] The present invention adopts a two-step battery information verification method to ensure battery information matching, solves the problem of battery information pairing errors in the prior art, and effectively prevents high-quality batteries from being stolen.

[0057] A cloud-based collaborative platform deploys blockchain nodes and privacy computing modules for one-time verification code distribution, battery lifecycle tracking, and cross-regional resource scheduling.

[0058] Blockchain node data records adopt a layered storage architecture and anti-tampering mechanism.

[0059] The layered storage architecture includes storing basic battery information in the alliance chain and storing user privacy data in the private chain.

[0060] The anti-tampering mechanism includes battery replacement time, geographic location, and battery serial number, which are written into the block using an encryption algorithm.

[0061] Intelligent battery module, including a multi-dimensional sensor group and an anti-tamper self-locking mechanism;

[0062] Multi-dimensional sensor group includes voltage sensor, temperature sensor, etc.

[0063] A voltage sensor is a sensor that can sense the voltage being measured and convert it into a usable output signal. It is used to monitor the voltage of the battery.

[0064] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal, and is used to monitor the temperature of the battery.

[0065] By setting up a multi-dimensional sensor group, the safety performance of battery use is guaranteed.

[0066] The anti-tamper self-locking mechanism cuts off the charging and discharging circuits when triggered and reports security events via the cellular network.

[0067] The payment gateway module is used for battery swap settlement with user terminals, supports zero-knowledge proof protocol and docking with the central bank's digital currency system to realize anonymous atomic transactions.

[0068] The transaction process of the payment gateway module includes: after the user selects the battery swap service, an encrypted payment voucher containing the time and amount is generated. The payment voucher is digitally signed by the battery swap cabinet and transmitted to the blockchain network, triggering the smart contract to complete the account settlement.

[0069] The intelligent battery exchange cabinet module also adapts to the storage allocation unit and the fire linkage unit;

[0070] Adaptive slot allocation unit: optimizes slot allocation strategies based on remaining battery power, age, and user history.

[0071] Fire linkage unit: Utilizes intelligent battery modules to quickly handle emergencies. A HFC-227ea fire extinguishing device is installed to work with the battery compartment. When the temperature sensor detects an abnormal temperature rise, such as exceeding 82°C, the HFC-227ea fire extinguishing device will automatically start and cut off the power supply to the adjacent compartments.

[0072] Heptafluoropropane fire extinguishing device is mainly a device filled with heptafluoropropane gas as the fire extinguishing agent. The heptafluoropropane fire extinguishing agent in the heptafluoropropane fire extinguishing device is a colorless, odorless, non-conductive, and non-secondary pollution gas. It has the characteristics of cleanliness, low toxicity, good electrical insulation, and high fire extinguishing efficiency. In particular, it has no damage to the ozone layer and has a relatively short residual time in the atmosphere. Its environmental performance is significantly better than that of halogenated hydrocarbons.

[0073] The present invention solves the security risks of identity counterfeiting in the existing technology by setting up a user terminal module, an intelligent battery exchange cabinet module, a transfer guarantee module, a cloud collaboration platform, an intelligent battery module and a payment gateway module, and ensures battery information matching, effectively preventing high-quality batteries from being replaced.

In the second step, the user's face is recognized by the biometric collection unit to obtain the biometric features of the face. The biometric data is locally encrypted and uploaded to the cloud for learning and comparison with the pre-stored original data. If the comparison is successful, the battery can be swapped. If the comparison fails, the battery cannot be swapped.
