Description

Technical Field

[0001] This invention relates to the field of new energy vehicle technology, and more specifically, to an anti-theft system and method for a pure electric light truck power battery. Background Technology

[0002] Currently, new energy vehicles are experiencing explosive growth, with power batteries accounting for over 50% of the total vehicle cost. For example, the power battery cost for a vehicle with a 100kWh battery is approximately 110,000 yuan. Consequently, some cases of power battery theft have emerged this year, particularly involving pure electric light trucks. While new energy passenger vehicles require specialized equipment (lifts) to view or remove their batteries, pure electric light truck power batteries are exposed and suspended on both sides of the chassis, connected by bolts and brackets, allowing for removal without lifting. Furthermore, current technology lacks specific anti-theft designs for power batteries, making them easy targets for theft, leading to frequent thefts of light truck power batteries.

[0003] Therefore, how to provide an anti-theft system and method for the power battery of pure electric light trucks has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0024] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0025] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0027] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0029] See Figure 1 and Figure 2According to a first aspect of the present invention, an anti-theft system for a pure electric light truck's power battery is provided, comprising a power battery pack 1, a high-low voltage connector 2, a battery controller, a high-low voltage wiring harness 3, a vehicle body controller, an audible and visual alarm, and a T-box (vehicle remote terminal). The power battery pack 1 supplies power to the pure electric light truck; the high-low voltage connector 2 is electrically connected to the power battery pack 1; the high-low voltage wiring harness 3 is connected between the battery controller and the high-low voltage connector 2. The battery controller is electrically connected to the vehicle body controller, and the vehicle body controller is electrically connected to the audible and visual alarm; the T-box is signal-connected to the battery controller. The battery controller monitors the interlocking state of the high-low voltage connector 2; when the high-low voltage wiring harness 3 of the pure electric light truck's power battery is disconnected (stolen), and the battery controller detects an abnormality in the interlocking state of the high-low voltage connector 2, the battery controller issues an alarm signal. The vehicle body controller receives the alarm signal from the battery controller. First, the vehicle body controller controls the audible and visual alarm to emit an audible and visual alarm. At the same time, the vehicle body controller sends an alarm signal to the T-BOX, and the T-BOX sends a message to the owner's mobile phone to inform them that the vehicle has been stolen. This achieves vehicle alarm plus owner-initiated alarm, improving the anti-theft effect and giving thieves a strong psychological deterrent.

[0030] Further, according to the above scheme, the system also includes a battery control box 5, which is installed on the frame 4 of the pure electric light truck. The battery control box 5 is located at the center of the frame 4, and the battery controller is installed inside the battery control box 5. The power battery packs 1 are respectively installed on opposite sides of the frame 4, and the battery control box 5 is located between the two power battery packs 1. The location of the battery control box 5 between the two power battery packs 1 improves the concealment of the battery control box 5, making it difficult to disassemble and damage. When thieves steal the battery packs, they are unlikely to find the battery control box 5, ensuring that the battery control box 5 can issue an alarm signal in a timely manner.

[0031] See Figure 3 According to a second aspect of the present invention, a method for preventing theft of a power battery in a pure electric light truck is provided, wherein the pure electric light truck includes the anti-theft system for a power battery in a pure electric light truck according to the first aspect of the present invention, the method comprising:

[0032] Step S1: The battery controller detects the interlock status of the high and low voltage connectors 2;

[0033] Step S2: When the battery controller detects an abnormality in the interlocking state of the high and low voltage connectors 2, the battery controller sends alarm signals to the body controller and the T-BOX respectively;

[0034] Step S3: The body controller receives the alarm signal from the battery controller, and the body controller controls the audible and visual alarm to emit an audible and visual alarm; and / or, the T-BOX receives the alarm signal from the battery controller and sends an alarm signal to the mobile phone of the owner of the pure electric light truck.

[0035] In summary, the technical solution of this invention utilizes the interlocking state of the high and low voltage connectors of the entire vehicle to achieve effective anti-theft without increasing hardware costs. It combines vehicle alarm with owner-initiated alarm, enhancing the anti-theft effect and providing a strong psychological deterrent to thieves. The battery controller remains operational even after the vehicle is powered off, continuously monitoring the interlocking state of the high and low voltage connectors of the power battery. In the event of an abnormal disconnection, the battery controller sends a signal to the vehicle controller for an audible and visual alarm, and simultaneously sends a signal to the T-box (vehicle remote terminal). The T-box then sends a message to the owner's mobile phone, informing them that the vehicle has been stolen.

[0036] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention.
