Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, and in particular to a battery pack anti-theft system. Background Art

[0002] Secondary batteries, also known as rechargeable batteries or storage batteries, are batteries that can be recharged after discharge to reactivate the active materials and continue to be used. The main rechargeable batteries currently on the market include nickel-metal hydride, nickel-cadmium, lead-acid (lead storage batteries), and lithium-ion (including lithium batteries and lithium-ion polymer batteries). In an era of rapid technological advancement, secondary batteries are widely used in high-tech electronic devices such as laptops, mobile phones, and camcorders. Furthermore, with the rapid development of new energy vehicles amidst the energy crisis, secondary batteries are also widely used as battery packs in automobiles. As core components of electric vehicles, secondary batteries possess a high level of technological content and are expensive to manufacture. Consequently, electric vehicle battery packs, especially portable ones that are smaller and lighter, are vulnerable to theft. As thieves' methods and tactics continue to evolve and their tools become more advanced, traditional anti-theft methods are no longer adequate. Therefore, there is an urgent need to develop effective anti-theft measures for electric vehicle battery packs.

[0003] For example, authorization announcement number CN207233802U discloses a battery pack anti-theft structure, comprising a battery pack, a bracket for placing and fixing the battery pack, and an electromagnetic lock assembly fixedly connected to the bracket and used to protect the battery pack and engage with the bracket; the battery pack comprises a battery box shell and a fixing beam fixedly connected to the battery box shell, the battery box shell comprises a box body and a box cover that abut against each other, and the fixing beam is provided with a bayonet and a fixing hole; the bracket comprises a support plate, and the support plate is provided with a plurality of mounting holes corresponding to the fixing holes and the bayonet; the electromagnetic lock assembly comprises an electromagnetic lock and a mounting bracket for fixing the electromagnetic lock, and a retractable lock head corresponding to the fixing hole is provided on one side of the electromagnetic lock. However, this method locks and fixes the battery pack of an electric vehicle to the vehicle. The disadvantages of this anti-theft method are that mechanical locks and electronic-mechanical locks are easy to crack, and require many additional mechanical and electronic components, increasing the manufacturing cost of the vehicle. None of the above anti-theft methods can effectively prevent the battery of an electric vehicle from being stolen. Summary of the Invention

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0019] The present invention discloses a battery pack anti-theft system, including an on-board Bluetooth arranged in a vehicle. The on-board Bluetooth may be as disclosed in authorization number CN210628474U, or may be of other structures, which are prior art and the present invention will not go into details here, as they all fall within the scope of protection of the present invention. The on-board Bluetooth interacts with the battery swap station to obtain a lock or unlock signal, and sends the obtained signal to the controller, which controls the anti-theft component arranged on the battery pack to complete the locking or unlocking of the battery pack. The design is sophisticated. When swapping batteries, the on-board Bluetooth interacts with the battery swap station to obtain information, and the controller can control the anti-theft component to unlock the battery pack to achieve normal battery swapping. The operation is simple and convenient, the operation is stable and reliable, and it has a wide applicability.

[0020] like Figures 1 to 2 As shown, in a preferred embodiment of the present invention, the anti-theft component at least includes a gun body, and the gun body is provided with a gun head 1 that can be extended and clamped on the vehicle, and one side of the gun body is provided with a connection area 2 that is movably connected to the battery pack, and the other side is provided with a driving area 3. The driving area 3 can be driven downward by the driving assembly, so that the gun head 1 is extended and clamped on the vehicle, and the connection area 2 locks the battery pack. The connection area 2 can be clamped inside the battery pack. Of course, it can also be other locking structures, all of which fall within the protection scope of the present invention and will not be described in detail here.

[0021] In addition, the drive area 3 includes at least a rack, and the drive assembly includes a drive motor 7. A gear 6 is fixed to the motor shaft of the drive motor 7, and the gear 6 and the rack are meshed with each other. The gun body is also provided with a first limit block 4 and a second limit block 5. The first limit block 4 and the second limit block 5 are located on both sides of the drive area 3 to limit the movement of the drive assembly and prevent damage to the gun tip.

[0022] The battery pack is also equipped with a warning device, which is connected to the user client and the controller and is a buzzer or warning light. In addition, the battery pack is equipped with a battery sensor. When the battery sensor does not receive an unlock signal but senses that the battery is being forcibly removed, it will issue an anti-theft warning to the user client, allowing the user client to confirm its status and whether to select an alarm.

[0023] If a vehicle experiences an emergency and the battery pack needs to be removed outside a battery swap station, the user client can send a command to the controller, which then controls the anti-theft component to unlock the battery pack, meeting the needs of different operating conditions and improving work efficiency. Furthermore, in the present invention, the user client can be a mobile phone, computer, tablet, or wristband, and of course, other devices are also possible, all of which fall within the scope of protection of the present invention.

[0024] In the present invention, the controller is also connected to the user client through a communication component to complete information interaction between the two. The controller sends the target data to the user client through the communication component, and determines whether the sending of the target data is completed within the specified sending time. If the sending of the target data is completed within the specified time, it is determined whether the confirmation information feedback from the user client is obtained within the specified time, thereby avoiding the loss or non-receipt of information and improving the accuracy of communication.

[0025] In the above, the specified duration includes the following steps: obtaining the transmission speed of the data transmission of the current communication component, and calculating the specified sending duration based on the transmission speed and the size of the target data. Specifically, by recording the time during the sending, it is determined whether the specified sending duration is exceeded. The specified sending duration is generally a preset value, and the duration is generally 2-6 seconds. In this embodiment, it is preferably 3 seconds. The specified sending duration can also be formulated according to the transmission speed of the signal. The formulation step is performed periodically, and the execution cycle interval is generally but not limited to 20 minutes. The specific steps include obtaining the transmission speed value at a specified time point within the cycle interval. The specified time point is generally not limited to the 3rd minute, 6th minute, 9th minute, 12th minute, 15th minute within the cycle, and the start and end time points of each cycle interval; after removing the maximum and minimum transmission speed values, calculating the average transmission speed of the current cycle; and deriving the specified sending duration based on the average transmission speed and the size of the transmitted data.

[0026] It should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation method can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
