Description

Technical Field

[0001] The present invention relates to the technical field of battery detection, and in particular to a battery damage detection, positioning and alarm system. Background Art

[0002] As the number of new energy vehicles continues to increase, more and more problems are generated during the use of new energy vehicles. Among them, the battery pack shell is bumped and other problems are increasingly frequent during use; in extreme cases, the battery cell inside may be deformed and short-circuited due to stress, and external conductive liquid may enter the battery to cause internal short circuit, thus causing battery fire accidents.

[0003] However, battery testing is mostly carried out during battery production and factory inspection, which cannot effectively monitor whether the battery shell of new energy batteries is damaged or broken during use. In addition, since the battery of new energy vehicles is located at the bottom of the vehicle chassis, drivers often fail to notice the bottom collision and continue to drive the vehicle, which can easily lead to accidents due to untimely maintenance of battery collisions.

[0004] Therefore, in order to solve the above problems, the applicant has studied and designed a battery damage detection, positioning and alarm system based on the principle that wire breakage causes current changes. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a battery damage detection, positioning and alarm system, the purpose of which is to deform the detection layer through the depression caused by bumps, thereby causing the wires of the X-axis wire array and the Y-axis wire array to break or deform, causing changes in the current in the wires, and judging the damaged part and area of ​​the battery based on the change in current, objectively solving the technical problem that the damage caused by bumps during use of existing batteries cannot be detected and located in real time.

[0006] In order to solve the above technical problems, the technical solution provided by the present invention is: a battery damage detection, positioning and alarm system, comprising a detection layer wrapped around the outer ring of the battery, the detection layer comprising an upper insulating layer, a middle insulating layer and a lower insulating layer arranged in sequence, an X-axis wire row is arranged between the upper insulating layer and the middle insulating layer, a Y-axis wire row is arranged between the middle insulating layer and the lower insulating layer, and the X-axis wire row and the Y-axis wire row both include a plurality of wires arranged in parallel;

[0007] It also includes a detection controller electrically connected to the X-axis wire row and the Y-axis wire row, and the detection controller is also provided with an alarm.

[0008] Furthermore, the conductor arrangement directions of the X-axis conductor array and the Y-axis conductor array are perpendicular to each other, and the conductors of the X-axis conductor array and the Y-axis conductor array are both made of graphite.

[0009] Furthermore, both ends of the X-axis wire array are electrically connected to the detection controller, and both ends of the Y-axis wire array are electrically connected to the detection controller.

[0010] Furthermore, the detection layer is arranged between the battery pack and the battery shell, and the detection layer is deformed according to the depression of the battery shell.

[0011] The advantages of the present invention over the prior art are: the present invention coats a detection layer on the outer ring of the battery pack, so that when the battery shell is damaged by collision, the detection layer is deformed, thereby causing the wires of the X-axis wire row and the Y-axis wire row arranged between the upper, middle and lower insulating layers to break, causing the current passing through the detection controller to change. The detection controller determines the location and area of ​​the battery damage based on the current change, achieving the technical effect of real-time monitoring of whether the battery is intact during use. The present invention has a simple structural design, calculates the size and location of the damaged area through data and algorithms, and makes accurate, timely and efficient judgments. During driving, the driver can be reminded of the damage of the battery caused by collision in a timely manner, and timely inspection and maintenance can be carried out to avoid accidents.

[0015] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0016] In the description of the embodiments of the present invention, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the invented product is usually placed when used. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0017] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0018] In the description of the embodiments of the present invention, "plurality" means at least 2.

[0019] In the description of the embodiments of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Embodiment 1:

[0021] Combined with Figure 1 A battery damage detection, positioning and alarm system comprises a detection layer wrapped around the outer ring of the battery, the detection layer comprises an upper insulating layer 1, a middle insulating layer 2 and a lower insulating layer 3 arranged in sequence, an X-axis wire row 4 is arranged between the upper insulating layer 1 and the middle insulating layer 2, a Y-axis wire row 5 is arranged between the middle insulating layer 2 and the lower insulating layer 3, and the X-axis wire row 4 and the Y-axis wire row 5 both comprise a plurality of wires arranged in parallel;

[0022] It also includes a detection controller 6 electrically connected to the X-axis wire array 4 and the Y-axis wire array 5 , and an alarm 7 is also provided on the detection controller 6 .

[0023] A preferred implementation of this embodiment is that the X-axis wire array 4 and the Y-axis wire array 5 are arranged perpendicularly to each other, and the wires of the X-axis wire array 4 and the Y-axis wire array 5 are both made of graphite.

[0024] During implementation, the X-axis wire row is arranged along the X-axis, and the Y-axis wire row is arranged along the Y-axis. The double-layer wire row arranged in a vertical relationship can judge the degree of damage based on the current change. If only the Y-axis wire row has a current change, it means that the damage is not serious and does not endanger the normal operation of the battery. You can continue to drive, but you need to check and repair it in time. When the current changes in both the X-axis wire row and the Y-axis wire row, it means that the damage is serious and there is a possibility of endangering the normal operation of the battery. It is recommended to check and repair it immediately.

[0025] In a preferred implementation of this embodiment, both ends of the X-axis wire array 4 are electrically connected to the detection controller 6, and both ends of the Y-axis wire array 5 are electrically connected to the detection controller 6. The detection layer is disposed between the battery pack and the battery shell, and the detection layer is deformed according to the depression of the battery shell.

[0026] Combined with Figure 2 In a specific implementation, after the battery is damaged, the detection layer is deformed, causing the wires of the X-axis wire row and the Y-axis wire row to be disconnected, causing the current to change. The detection controller determines the damaged area and position according to the change in current.

[0027] When the damaged location is extremely important, it means that the danger is high. The detection controller sends a signal to the alarm, and the alarm sends an audible and optical alarm. It is recommended to stay away from the vehicle immediately to avoid explosion. When the damaged location is generally dangerous, it is also recommended to stay away from the vehicle immediately to avoid explosion when judging the size of the damaged area. When the damaged area is small and the danger is low, report the fault for detection and maintenance.

[0028] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
