Description

Technical Field

[0001] This invention relates to the field of anti-theft technology for power battery systems, and in particular to an anti-theft method, device, vehicle, and storage medium for power battery systems. Background Technology

[0002] As one of the three major components of electric vehicles (battery, motor, and electronic control), the power battery is the power source of the entire vehicle system and has always been regarded as a landmark technology in automotive development. Its performance directly affects the vehicle's driving range, and its importance is self-evident.

[0003] The power battery system accounts for 40% to 50% of the total vehicle cost, and it is susceptible to theft and resale. Furthermore, vehicle users may modify the power battery system, which poses a significant risk to both the system and the vehicle itself. To avoid the risks associated with mixing or modifying different power battery systems, current technologies generally employ corresponding mechanical designs, either increasing the difficulty of theft or triggering an alarm on the protection board.

[0004] The disadvantages of this approach are that the structure of the power battery system changes significantly, and the cost of redesigning it is high and complex. In addition, if a dedicated power battery system protection device is used, the design difficulty will increase and space will be occupied. Summary of the Invention

[0017] Optionally, the anti-theft information of the current vehicle's power battery can be determined based on the result of whether the two devices match, including:

[0018] If a match is found, then the current vehicle's power battery anti-theft information is determined to be that the battery self-test has passed.

[0019] If an inconsistency is detected, the current vehicle's power battery anti-theft information is determined to be a battery code mismatch.

[0020] Optionally, the anti-theft method for the power battery system further includes:

[0021] Once it is determined that the current vehicle's power battery anti-theft information indicates a battery code mismatch, a battery code mismatch fault code is generated and fed back to the battery management system.

[0022] Optionally, the anti-theft method for the power battery system further includes:

[0023] If the current vehicle's power battery system contains multiple battery packs, then each battery pack generates corresponding protocol battery code information, and the battery pack and the corresponding protocol battery code information are recorded in the battery management system.

[0024] According to another aspect of the present invention, a power battery system anti-theft device is provided, the power battery system anti-theft device comprising:

[0025] The coding information determination module is used to perform the following actions during the initial low-voltage power-on phase of the current vehicle: the battery management system reports the first battery coding information of the current vehicle to the vehicle VCU, and determines that the first battery coding information is consistent with the agreed battery coding information.

[0026] The anti-theft information determination module is used to, after the current vehicle is powered on again at low voltage, report the second battery code information of the current vehicle through the battery management system, and determine the anti-theft information of the power battery of the current vehicle based on the second battery code information.

[0032] The technical solution of this invention involves the battery management system reporting the first battery code information of the current vehicle to the vehicle's VCU during the initial low-voltage power-on phase, and confirming that the first battery code information is consistent with the agreed battery code information. After the current vehicle is powered on again, the battery management system reports the second battery code information of the current vehicle, and determines the anti-theft information of the current vehicle's power battery based on the second battery code information.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0041] Example 1

[0042] Figure 1This is a flowchart illustrating a method for preventing theft of a power battery system according to Embodiment 1 of the present invention. This embodiment is applicable to encrypting and preventing theft of power battery systems to avoid risks arising from the mixing or modification of different power battery systems. This method can be executed by a power battery system anti-theft device, which can be implemented in hardware and / or software. This anti-theft device can be configured in a power battery system vehicle or a power battery system vehicle with a battery swapping platform. Figure 1 As shown, the anti-theft method for this power battery system includes:

[0043] S110. During the initial low-voltage power-on phase of the current vehicle, the battery management system reports the first battery code information of the current vehicle to the vehicle VCU and determines that the first battery code information is consistent with the agreed battery code information.

[0044] The first battery code information is the complete battery code information of the current vehicle's power battery system. The battery management system reports the first battery code information to the vehicle's VCU.

[0045] When the power battery system leaves the factory, the first battery code information corresponding to the power battery system is written into the corresponding battery management system. The first battery code information can be implemented in accordance with the requirements of GB / T34014-2017. The first battery code information may include, but is not limited to, information such as manufacturer, battery type, traceability code, and production date.

[0046] Specifically, for power battery systems containing multiple battery packs, each battery pack has corresponding battery coding information. The battery coding information corresponding to each battery pack needs to be written into the corresponding battery management system when the power battery system leaves the factory.

[0047] Similarly, for power battery systems with battery swapping platforms, the battery code information corresponding to the power battery system is also written into the corresponding battery management system when the power battery system leaves the factory.

[0048] The agreed battery code information is specified by the vehicle VCU and the power battery system manufacturer after the power battery system is assembled at the vehicle manufacturer. For a specific model of power battery system, its agreed battery code information conforms to the battery system coding rules agreed upon by the vehicle VCU and the power battery system manufacturer.

[0049] Specifically, during the initial low-voltage power-on phase of the vehicle, a self-check is performed. In addition to routine self-checks, the battery coding of the power battery system is also checked. After the battery management system reports the first battery coding information of the current vehicle to the vehicle's VCU, it determines whether the first battery coding matches the agreed battery coding information. If the first battery coding information matches the agreed battery coding information, the initial power-on of the current vehicle passes. At this time, the vehicle's VCU allows the high-voltage power-on and records all the first battery coding information of the current vehicle in its cache.

[0050] S120. After the current vehicle is powered on again, the second battery code information of the current vehicle is reported through the battery management system, and the anti-theft information of the power battery of the current vehicle is determined based on the second battery code information.

[0051] The second battery code information is obtained by the battery management system when the vehicle is restarted, i.e. when the vehicle is powered on again at low voltage.

[0052] It is understandable that the second battery code information is the battery code information that is written into the corresponding battery management system when the power battery system is manufactured and the vehicle is connected to low voltage power again. In other words, the second battery code information is the battery code information corresponding to the power battery system when the vehicle is connected to low voltage power again.

[0053] Similarly, the second battery code information can be implemented in accordance with the requirements of GB / T 34014-2017. The second battery code information may include, but is not limited to, information such as manufacturer, battery type, traceability code, and production date.

[0054] After the vehicle is powered on again with low voltage, if the vehicle's power battery system is a battery system with a battery swapping platform, it is determined whether the second battery code information is consistent with the agreed battery code information, and the anti-theft information of the current vehicle's power battery is determined based on the result of whether they are consistent; if the vehicle's power battery system is a battery system without a battery swapping platform, it is determined whether the first battery code information and the second battery code information are consistent, and the anti-theft information of the current vehicle's power battery is determined based on the result of whether they are consistent.

[0055] Based on the above, if a match is found, the current vehicle's power battery anti-theft information is determined to be a battery self-test success; if a mismatch is found, the current vehicle's power battery anti-theft information is determined to be a battery code mismatch.

[0056] Once it is determined that the current vehicle's power battery anti-theft information indicates a battery coding mismatch, a fault code for battery coding mismatch is generated and fed back to the battery management system. The battery management system performs corresponding processing based on the fault code, for example, locking the power battery system and uploading the fault information to the monitoring platform, indicating that the power battery system's battery coding information is mismatched.

[0057] In cases where after-sales personnel proactively replace the power battery system, if the battery coding information of the power battery system does not match, professional after-sales personnel can, according to their flashing permissions, flash the coding information of the power battery system to be replaced into the vehicle's VCU cache; or, after-sales personnel can use their permissions to flash the power battery system coding, so that when the vehicle is powered on again, the agreed battery coding information in the vehicle's VCU will be consistent with the current vehicle's battery coding information, and the self-test process will continue normally.

[0058] The technical solution of this invention involves the battery management system reporting the first battery code information of the current vehicle to the vehicle's VCU during the initial low-voltage power-on phase, and confirming that the first battery code information is consistent with the agreed battery code information. After the current vehicle is powered on again, the battery management system reports the second battery code information of the current vehicle, and determines the anti-theft information of the current vehicle's power battery based on the second battery code information. This invention solves the problems of high difficulty, high cost, and complexity in protecting power battery systems from theft, achieves the uniqueness of the power battery system, is simple to operate and easy to implement, and effectively prevents unauthorized modification of the power battery system and prevents its theft.

[0059] Example 2

[0060] Figure 2 This is a flowchart of an anti-theft method for a power battery system provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment provides an optional implementation method. For example... Figure 2 As shown, the anti-theft method for this power battery system includes:

[0061] S210. During the initial low-voltage power-on phase of the current vehicle, the battery management system reports the first battery code information of the current vehicle to the vehicle VCU and determines that the first battery code information is consistent with the agreed battery code information.

[0062] For example, for a power battery system of a certain model, its agreed battery code information can be divided into two parts. The first part of the code structure represents the first 12 bits of the agreed battery code information. The first part of the code structure is fixed and includes X1 to X14 basic structures. The meaning of the corresponding structures can be found in Table 1 below. It can be seen that the first part of the code structure may include, but is not limited to, the manufacturer code, product type code, battery type code, specification code, and traceability information code. Among them, the specification code and traceability information code can be specified by the power battery system manufacturer, and the power battery system manufacturer will inform the vehicle VCU manufacturer of the corresponding coding method.

[0063] Basic structure meaning X1 X2 X3 Manufacturer code X4 Product type code X5 Battery type code X6 X7 Specification Code X8 X9 X10 X11 X12 X13 X14 Traceability Information Code

[0064] Table 1 Code Structure (Part 1)

[0065] The second part of the code structure represents the last 12 bits of the battery coding information. The second part of the code structure is not fixed and can be selected and set by those skilled in the art according to the specific situation of the power battery system. The second part of the code structure includes X15 to X36 basic structures, and their corresponding meanings can be found in Table 2 below. It can be seen that the second part of the code structure may include, but is not limited to, the production date code, serial number, battery box rated capacity, battery box nominal voltage, connector code, locking mechanism code, and box structure code.

[0066] Basic structure meaning X15 X16 X17 Production date code X18 X19 X20 X21 X22 X23 Serial Number X24 X25 X26 Battery box rated capacity X27 X28 X29 X30 Battery box nominal voltage X31X32 Connector code X33X34 Locking mechanism code X35X36 Box structure code

[0067] Table 2 Code Structure (Part Two)

[0068] Specifically, during the initial low-voltage power-on phase of the vehicle, the battery management system reports the vehicle's first battery code information L1 to the vehicle's VCU. The vehicle's VCU compares the code information one by one according to the agreed rules to ensure that the first battery code information L1 reported by the corresponding power battery system matches the agreed battery code information L2. If the power-on self-test passes, the vehicle's VCU allows the high-voltage power-on and records all the first battery code information L1 reported by the battery management system in the cache.

[0069] It is understood that the first battery coding information L1 can extract X1 to X24 and compare it with X1 to X12 contained in the agreed battery coding information L2. Alternatively, the first battery coding information L1 can be compared with all the information in the agreed battery coding information L2. There are no restrictions on the content to be compared in the field of battery coding information.

[0070] S220. After the current vehicle is powered on again, the second battery code information of the current vehicle is reported through the battery management system, and the anti-theft information of the power battery of the current vehicle is determined based on the second battery code information.

[0071] Specifically, after the current vehicle is powered on again at low voltage, the battery management system reports the second battery code information L3 of the current vehicle. If the current vehicle's power battery system is a battery system without a battery swapping platform, the vehicle's VCU, during the self-test phase, first retrieves the first battery code information L1 from the cache and compares the second battery code information L3 with the first battery code information L1. If the second battery code information L3 matches the first battery code information L1, the power-on self-test passes, and the vehicle's VCU is allowed to connect to high voltage.

[0072] For battery systems suitable for battery swapping platforms, battery coding follows the requirements of GB / T 40098-2021, "Code Rules for Power Battery Boxes for Electric Vehicles." Power battery manufacturers must clearly identify the battery system's specification code to distinguish it from ordinary power batteries, and must also label the battery box's rated capacity, nominal voltage, connector code, locking mechanism code, and box structure code according to standard requirements. Based on the above embodiment, after the battery management system reports the second battery code information of the current vehicle, it determines whether the current vehicle's power battery system is a battery system with a battery swapping platform based on the specification code in the second battery code information.

[0073] Specifically, if the current vehicle's power battery system is a battery system with a battery swapping platform, and the current vehicle's power battery system is identified as a battery swapping system according to the agreed coding rules, then it is not necessary to verify all battery codes. The following verification mode is adopted: The vehicle's VCU directly checks whether the agreed battery code information of the power battery system after battery swapping is consistent with the original agreed battery code information L2, that is, it judges whether the second battery code information is consistent with the agreed battery code information. If the verification is consistent, the power battery system is considered to be normal and no fault is reported.

[0074] The battery swapping management platform for power battery systems possesses all power battery system information. The platform can fully verify the battery coding information of power battery systems. If the corresponding power battery system does not belong to the battery swapping management platform, the platform can handle the matter according to regulations.

[0075] S230. After determining that the current vehicle's power battery anti-theft information is a battery code mismatch, a battery code mismatch fault code is generated and the fault code is fed back to the battery management system.

[0076] For general-purpose power battery systems, after determining that the current vehicle's power battery anti-theft information indicates a battery coding mismatch, the two agreed battery coding information L2 (x1x2x3…x12) can be further compared. If the two agreed battery coding information L2 (x1x2x3…x12) match, a minor fault is reported, and the vehicle proceeds with high-voltage connection according to the normal procedure. If the two agreed battery coding information L2 do not match, it is considered that the power battery system may have been replaced, the vehicle's VCU high-voltage self-test fails, and a serious fault is reported to the vehicle's VCU. High-voltage connection is not allowed in the vehicle. At the same time, the vehicle's VCU will generate a battery coding mismatch fault code and feed the fault code back to the battery management system. The battery management system processes the fault according to the set fault handling mode and uploads the fault information to the monitoring platform, indicating a coding mismatch.

[0077] The technical solution of this invention involves writing the power battery system's coding information into the battery management system of the power battery system. By establishing coding rules between the battery management system and the vehicle's VCU manufacturer, the uniqueness of the battery system is ensured. This method is simple, easy to implement, and does not increase space or cost. Furthermore, the uniqueness and compliance of the battery coding are verified during the vehicle's self-inspection phase, effectively preventing unauthorized modifications by users and mitigating the problem of stolen and reused battery systems. In addition, feasible solutions are provided for after-sales maintenance scenarios and power battery systems used in battery swapping.

[0096] The protocol battery code information generation module is used to generate corresponding protocol battery code information for each battery pack if the current vehicle's power battery system contains multiple battery packs, and record the battery pack and the corresponding protocol battery code information to the battery management system.
