DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] First, some technical terms in the present application are explained to facilitate those skilled in the art to understand the present application.

[0036] The term "outside" in the present application means that when looking into the box from the opening side of the box body 2, the second stopper is located outside the first stopper, and the first stopper is located outside the power supply circuit.

[0037] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0038] In a first aspect, an embodiment of the present application provides a power battery anti-theft device.

[0039] In one embodiment, referring to Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the power battery anti-theft device of this application. Figure 1 As shown, the power battery anti-theft device includes:

[0040] A low speed alarm 1, which is connected to a power battery via a power supply circuit and is powered by the power battery;

[0041] The battery protection box includes a panel, a first blocker, and a second blocker; the panel surrounds the power battery to form a box body 2 with an open side; the first blocker and the second blocker are installed on the open side of the box body 2, the first blocker blocks the power supply circuit from the outside, and the second blocker presses the first blocker from the outside; the connection mechanism between the second blocker and the box body 2 is electrically connected to the first pin of the low-speed alarm 1 through the ground wire 15.

[0042] The battery protection box is a key structural component used to carry, fix, protect and integrate battery packs in new energy vehicles. It can protect the battery from damage when it is hit or squeezed by the outside world, and plays a key role in the safe operation and protection of the battery module. The enclosure, first stopper and second stopper of the battery protection box are made of high-strength metal materials, which play the role of support, resistance to mechanical shock, mechanical vibration and environmental protection (waterproof and dustproof). For the purpose of lightweighting, the enclosure, first stopper and second stopper of the present application are preferably made of aluminum plates or aluminum strips. In some embodiments of the present application, the bottom of the battery protection box is a hollow structure to prevent water accumulation in the battery protection box.

[0043] A low speed alarm 1, also known as an Acoustic Vehicle Alerting System (AVAS), is a safety device specially designed for electric vehicles (EVs).

[0044] In this embodiment, the original battery protection box and low-speed alarm 1 of the vehicle are slightly modified, and no new functional units are added, so the cost is very low. In this embodiment, the first block is used to block the power supply circuit from the outside, and the second block is pressed from the outside. The connection mechanism between the second block and the box body 2 is electrically connected to the first pin of the low-speed alarm 1 through the ground wire 15. If a thief wants to steal the power battery, he must first remove the connection mechanism between the second block and the box body 2. In this process, the ground wire 15 is also removed, causing the low-speed alarm 1 to alarm. At this time, the power battery is still supplying power to the low-speed alarm 1 through the power supply circuit. Therefore, there is no need to install a separate battery for the low-speed alarm 1. After the alarm is issued, the thief needs to continue to remove the second block, the first block, the power supply circuit, and even the connection mechanism between the power battery and the box body 2, which buys time for the user to prevent the power battery from being stolen.

[0045] Further, in some embodiments, Figure 1 As shown, the power supply circuit includes a positive battery electrode 8, a negative battery electrode 7, a positive wire, and a negative wire. The two ends of the low speed alarm 1 are connected to the positive battery electrode 8 and the negative battery electrode 7 through the positive wire and the negative wire, respectively, and are powered by the power battery 3; the first stopper includes a first beam 4 and a second beam 5, and the first beam 4 and the second beam 5 are provided with bending parts at both ends, and the bending parts are connected to the side wall of the box body 2 through a bolt structure. Figure 1 As shown, the bent portions at both ends of the second crossbeam 5 are connected to the side wall of the box body 2 through stud three 11 and stud five 13, respectively, to shield the connection between the battery positive electrode 8 and the positive electrode wire from the outside; the bent portions at both ends of the first crossbeam 4 are connected to the side wall of the box body 2 through stud two 10 and stud six 14, respectively, to shield the connection between the battery positive electrode 7 and the negative electrode wire from the outside. In this embodiment, the second crossbeam 5 shields the battery positive electrode and the positive electrode wire from the outside, thereby preventing the thief from cutting the positive electrode wire from the outside or removing the connection mechanism between the battery positive electrode 8 and the positive electrode wire; the first crossbeam shields the negative battery positive electrode 7 and the negative electrode wire from the outside, thereby preventing the thief from cutting the negative electrode wire from the outside or removing the connection mechanism between the battery negative electrode 7 and the negative electrode wire. This embodiment solves the problem in the related art that before the thief disassembles the power battery, the thief first cuts off the power supply circuit between the power battery and the alarm device, causing the alarm device to lose power supply and fail to sound an alarm.

[0046] Furthermore, in one embodiment, the first baffle comprises a first baffle plate, at least two ends of the first baffle plate are provided with bent portions, the bent portions are connected to the side wall of the box body 2 by a bolt structure, and after installation, the opening side of the box body 2 is closed by the first baffle plate, and the power supply circuit is shielded from the outside by the first baffle plate. In this embodiment, the power supply circuit is completely shielded by the first baffle plate, which solves the problem in the related art that before the thief removes the power battery, the thief first cuts off the power supply wire between the power battery and the alarm device, causing the alarm device to lose power supply and fail to sound an alarm.

[0047] Further, in one embodiment, the second stopper includes a first longitudinal beam 6, and the first longitudinal beam 6 has bending portions at both ends, and the bending portions are connected to the side wall of the box body 2 through a bolt structure, and the bolt structure is connected to the ground wire 15, such as Figure 1 As shown, the bent parts at both ends of the first longitudinal beam 6 are connected to the side wall of the box body 2 through studs 19 and studs 12 respectively, and the grounding wire 15 is connected to the stud 19. After the stud 19 is removed, the grounding wire 15 is suspended. In this embodiment, by connecting the grounding wire 15 to the bolt structure, the thief must remove the bolt structure and disconnect the grounding wire 15 before removing the first longitudinal beam, thereby triggering the low-speed alarm 1 to alarm, solving the problem in the related art that no alarm is issued during the removal of the power battery.

[0048] Furthermore, in one embodiment, the power battery anti-theft device also includes: a telematics processor 16 (T-BOX), which is powered by a power battery and is communicatively connected to the low-speed alarm 1. After receiving the alarm signal from the low-speed alarm 1, the telematics processor 16 will send an alarm message to the cloud server, so that the cloud server can forward the alarm message to the user terminal of the new energy vehicle.

[0049] T-BOX is an intelligent terminal device that integrates vehicle body network and wireless communication functions, and is an important component of the Internet of Vehicles system. It connects the vehicle-mounted CAN bus and the external cloud platform to achieve communication and data exchange between vehicles (V2V), vehicles and infrastructure (V2I), and vehicles and the Internet (V2N).

[0050] The main functions of T-BOX include:

[0051] Data collection and storage: T-BOX accesses the CAN bus through an interface to collect vehicle information, vehicle controller information, motor controller information, battery management system BMS, on-board charger and other data, and saves them in the internal storage medium at certain time intervals.

[0052] Remote communication interface: provides services including driving data collection, driving trajectory recording, vehicle fault monitoring, vehicle remote query and control (such as unlocking and closing, air conditioning control, window control, etc.), driving behavior analysis, 4G wireless hotspot sharing, etc.

[0053] Multiple interface connections: T-BOX has various interfaces to connect to the bus, including the traditional controller area network CAN, local interconnect network LIN, and debugging interfaces RS232 / RS485 / USB2.0, as well as the new automotive bus, in-vehicle Ethernet (Ethernet).

[0054] Remote control: Through the mobile phone APP and TSP backend web page, you can obtain the real-time status of the vehicle and perform remote control, such as remotely opening the car door, car windows, trunk, air conditioning, etc.

[0055] Remote diagnosis: T-BOX can deeply read the car CAN bus data and private protocols, and transmit the data to the cloud server through the network to achieve remote diagnosis.

[0056] Location service: The vehicle position is located through the GPS module, and the data is transmitted to the cloud server. The owner can obtain vehicle condition reports, driving reports, fuel consumption statistics, fault reminders, violation inquiries, location trajectories, driving behavior, safety and anti-theft, appointment services, remote vehicle search and other information on the mobile APP.

[0057] In this embodiment, by setting up a communication connection between T-BOX and the low-speed alarm 1, T-BO will send an alarm message to the cloud server after receiving the alarm signal of the low-speed alarm 1, so that the cloud server can forward the alarm message to the user terminal of the new energy vehicle, and can notify the user through WeChat, SMS or platform message when the user is far away from the vehicle, which solves the problem in the related technology that the user cannot hear the alarm sound when the user is far away from the vehicle, and also solves the problem in the related technology that the alarm information is not notified to the user until the power battery is cut off or stolen.

[0058] Furthermore, in one embodiment, the power battery anti-theft device also includes: an anti-theft switch, which is connected to the low-speed alarm 1 and is used to turn on or off the anti-theft mode of the low-speed alarm 1. The connection between the anti-theft switch and the low-speed alarm 1 can be a mechanical connection, an electrical connection, or a communication connection. In this embodiment, by setting the anti-theft switch, the user can freely choose whether to turn on the anti-theft mode of the low-speed alarm 1 according to the actual usage scenario. For example, when the power battery is normally repaired and disassembled, the user can turn off the anti-theft mode of the low-speed alarm 1 by operating the anti-theft switch to avoid false alarms; in a non-maintenance state, the user can turn on the anti-theft mode of the low-speed alarm 1 by operating the anti-theft switch.

[0059] In a second aspect, an embodiment of the present application also provides a power battery anti-theft method.

[0060] In one embodiment, referring to Figure 2 , Figure 2This is a flow chart of an embodiment of the power battery anti-theft method of the present application. Figure 2 As shown, the power battery anti-theft method includes:

[0061] Step S10: Detect whether the ground wire 15 in the power battery anti-theft device is disconnected;

[0062] Step S20: When it is detected that the grounding wire 15 is disconnected, an alarm message is issued.

[0063] like Figure 1 As shown, the power battery anti-theft device includes:

[0064] A low speed alarm 1, which is connected to a power battery via a power supply circuit and is powered by the power battery;

[0065] The battery protection box includes a panel, a first blocker, and a second blocker; the panel surrounds the power battery to form a box body 2 with an open side; the first blocker and the second blocker are installed on the open side of the box body 2, the first blocker blocks the power supply circuit from the outside, and the second blocker presses the first blocker from the outside; the connection mechanism between the second blocker and the box body 2 is electrically connected to the first pin of the low-speed alarm 1 through the ground wire 15.

[0066] Furthermore, if Figure 3 As shown, in one embodiment, step S10: detecting whether the ground wire 15 in the power battery anti-theft device is disconnected includes: step S101: detecting the level signal of the first pin of the low-speed alarm 1; step S102: when the level signal is suspended, judging that the ground wire 15 is disconnected. Under normal conditions, the connection mechanism between the second stopper and the box body 2 outputs a low-level voltage (<2V) to the first pin of the low-speed alarm 1 through the ground wire 15; when the connection mechanism between the second stopper and the box body 2 is removed, the low-level voltage is disconnected, and when the low-speed alarm 1 cannot detect the level signal of the first pin, an alarm message is issued. In this embodiment, by detecting the level signal of the first pin of the low-speed alarm 1 to determine whether the ground wire 15 is disconnected, the ground wire 15 can be detected to be disconnected when the thief removes the bolt structure between the second stopper and the side wall of the box body 2, thereby judging that the power battery is being stolen and disassembled.

[0067] Further, in one embodiment, step S20: when the ground wire 15 is detected to be disconnected, issuing an alarm message includes: issuing an alarm sound, and sending an alarm message to the cloud server, so that the cloud server forwards the alarm message to the user terminal of the new energy vehicle. In this embodiment, during the parking process of the vehicle, if someone maliciously disassembles the power battery, the buzzer sound emitted by the low-speed alarm 1 can play a deterrent role and remind the surrounding people that the vehicle has an abnormal situation, thereby reducing the probability of the power battery being stolen; when the power battery is abnormally disassembled, the platform will send a text message or WeChat reminder to the user through the information sent by T-BOX. After receiving the text message or WeChat reminder, the user can go to the scene in time to check, reducing the occurrence of the situation where the power battery is stolen after being aware of it, and avoiding the economic losses caused to the user by the theft of the power battery.

[0068] Furthermore, if Figure 5 As shown, in one embodiment, the power battery anti-theft method further includes: step S11: detecting whether the anti-theft switch is turned on; step S12: when the anti-theft switch is detected to be turned on, turning on the anti-theft mode of the low-speed alarm 1, and detecting whether the grounding wire 15 in the power battery anti-theft device is disconnected. In this embodiment, the anti-theft switch is used to configure the vehicle with two modes: normal power battery and power battery anti-theft. The power battery anti-theft mode can be turned off when the power battery is repaired and disassembled, solving the problem of false alarms.

[0069] Furthermore, in one embodiment, the power battery anti-theft method further includes: when it is detected that the anti-theft switch is not turned on, the anti-theft mode of the low-speed alarm 1 is not turned on, and whether the ground wire 15 in the power battery anti-theft device is disconnected is not detected.
