Description

Technical Field

[0001] This utility model relates to a battery anti-tampering solution, and in particular an anti-tampering battery module. Background Technology

[0002] With the maturity and development of new energy technologies, various battery packs are being used in a wide range of products, especially in new energy vehicles, where battery modules such as battery packs are becoming increasingly widespread. During the use of battery packs, tamper protection is a crucial issue. Current tamper protection methods primarily rely on increasing the physical difficulty of opening the pack, and the judgment process mainly depends on the signs of opening, which lacks precision and accuracy.

[0003] Therefore, the purpose of this utility model is to provide a new technical solution to solve the existing technical defects. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an anti-tamper battery module, which effectively solves the technical defects of insufficient anti-tamper protection of battery packs in the prior art.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A tamper-proof battery module includes a battery body and an tamper-proof component. The tamper-proof component includes a signal transmitter, a signal receiver, and an optical fiber electrically connected between the signal transmitter and the signal receiver. The optical fiber is wound around the outer periphery of the battery body at least once. The signal transmitter is used to transmit a signal, the signal receiver is used to receive a signal, and the optical fiber is used to transmit the signal transmitted by the signal transmitter to the signal receiver.

[0007] As a further improvement to the above technical solution, the signal transmitting end is a laser transmitter used to transmit laser signals, and the signal receiving end is a laser receiver used to receive laser signals.

[0008] As a further improvement to the above technical solution, the surface of the battery body is provided with an optical fiber receiving groove, and the optical fiber is wound around the battery body and then received in the optical fiber receiving groove.

[0009] As a first implementation improvement of the above technical solution, the optical fiber is wound multiple times in the vertical direction on the battery body.

[0011] As a third improvement to the above technical solution, the optical fiber is wound multiple times around the battery body in both the vertical and horizontal directions, and the optical fiber wound in the vertical direction and the optical fiber wound in the horizontal direction are integrated into one optical fiber.

[0012] As a fourth implementation improvement of the above technical solution, the optical fiber is wound multiple times on the battery body in both the up-down and left-right directions. The optical fiber wound in the up-down direction and the optical fiber wound in the left-right direction are two independent optical fibers, which are connected to an independent signal transmitting end and an independent signal receiving end.

[0013] As a further improvement to the above technical solution, the signal transmitting end includes a transmitting end plug-in portion, and the signal receiving end includes a receiving end plug-in portion. Both the transmitting end plug-in portion and the receiving end plug-in portion are used to connect to the outside to realize signal transmission.

[0023] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions.

[0024] Example 1:

[0025] Reference Figure 1 This utility model provides:

[0026] A tamper-proof battery module includes a battery body 1 and an tamper-proof component 2. The tamper-proof component 2 includes a signal transmitter 21, a signal receiver 22, and an optical fiber 23 electrically connected between the signal transmitter 21 and the signal receiver 22. The optical fiber 23 is wound around the outer periphery of the battery body 1, and the optical fiber 23 is wound around the battery body 1 at least once. The signal transmitter 21 is used to transmit signals, the signal receiver 22 is used to receive signals, and the optical fiber 23 is used to transmit the signals transmitted by the signal transmitter 21 to the signal receiver 22.

[0027] In practical applications, the signal transmitter 21 transmits signals intermittently or continuously. The emitted signals are transmitted to the signal receiver 22 via the optical fiber 23 and received by the signal receiver. Due to the easily broken physical characteristics of the optical fiber 23, when the battery body 1 is opened, the optical fiber 23 will break. After the optical fiber 23 breaks, the signal receiver 22 will not receive the signal. Therefore, the associated control device or system can determine that the battery body 1 has been disassembled or opened. Compared with the traditional method of judging whether the battery has been disassembled by disassembly marks, the anti-tampering scheme provided by this technical solution can accurately and quickly determine whether the battery has been disassembled, and the anti-tampering protection performance is more accurate.

[0028] In this embodiment, the signal transmitting end 21 is a laser transmitter used to transmit laser signals, and the signal receiving end 22 is a laser receiver used to receive laser signals. In some other embodiments, provided that performance requirements are met, the signal transmitting end 21 and the signal receiving end 22 can also be replaced by other suitable transmitters and receivers, with the same function and principle, which will not be described in detail here.

[0029] In this embodiment, the surface of the battery body 1 is provided with an optical fiber receiving groove. After the optical fiber 23 is wound around the battery body 1, the optical fiber 23 is received in the optical fiber receiving groove. In application, after the optical fiber 23 is received in the optical fiber receiving groove, the optical fiber 23 can be protected by filling and sealing the groove or applying protective adhesive to the groove opening to avoid accidental breakage of the optical fiber 23.

[0030] To ensure the reliability of the anti-tampering mechanism, the optical fiber 23 is wound multiple times around the battery body 1 in the vertical direction.

[0031] In addition, the anti-tamper battery module provided by this utility model also includes a signal transmitter 21 with a transmitter plug-in portion 211 and a signal receiver 22 with a receiver plug-in portion 221. Both the transmitter plug-in portion 211 and the receiver plug-in portion 221 are used for external connection to achieve signal transmission. It also includes a controller device. The signal transmitter 21 is electrically connected to the controller device through the transmitter plug-in portion 211, and the signal receiver 22 is electrically connected to the controller device through the receiver plug-in portion 221. When the battery body 1 is removed, the control device can send alarm and other information to the product's system (such as a vehicle technology system) or associated mobile terminal (mobile app, etc.) through the communication module, allowing the system or user to monitor the situation in real time.

[0032] Example 2:

[0033] Reference Figure 2 This embodiment is basically the same as embodiment 1, except that the optical fiber 23 is wound around the battery body 1 in the left-right direction multiple times.

[0034] Example 3:

[0035] Reference Figure 3-4 This embodiment is basically the same as Embodiment 1, except that the optical fiber 23 is wound multiple times around the battery body 1 in both the vertical and horizontal directions. The optical fiber 23 wound vertically and horizontally on the battery body 1 is a single optical fiber 23. Specifically, a single optical fiber 23 is used to complete the winding of the battery body 1 in both the vertical and horizontal directions. Winding the battery body 1 in both directions improves its tamper resistance.

[0036] Example 4:

[0037] Reference Figure 5 This embodiment is basically the same as Embodiment 1, except that: the optical fiber 23 is wound multiple times around the battery body 1 in both the vertical and horizontal directions. The optical fiber 23 wound vertically and horizontally are two independent optical fibers, connected to independent signal transmitters 21 and independent signal receivers 22. Specifically, the two ends of the optical fiber 23 wound vertically are connected to the first signal transmitter 21 and the first signal receiver 22, respectively, and the two ends of the optical fiber 23 wound horizontally are connected to the other signal transmitter 21 and the other signal receiver 22, respectively. The two sets of independent signal transmitters 21, signal receivers 22, and optical fiber 23 further enhance the reliability of the tamper protection.
