IBS is a key component for realizing the vehicle's start-stop and intelligent charging and discharging functions. On the one hand, IBS can analyze the battery's status (charging status, functional status, health status) by measuring the battery's voltage, current, temperature, etc. On the other hand, when a potential battery fault is found, it can report the fault in time.

[0004] In the prior art, the IBS is directly installed on the negative pole of the battery, and the PCB, connectors and other parts of the IBS will extend out of the negative pole.

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0043] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0044] In the description of this embodiment, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connected", and "connected" 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 communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0045] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0046] See also Figure 1 , Figure 2 In some embodiments, an IBS is provided, comprising a housing 1, a first electrical connection portion 2, a second electrical connection portion 3 and a third electrical connection portion 4, wherein the first electrical connection portion 2 is connected to the housing 1, and the second electrical connection portion 3 is connected to the housing 1 by a welding process. The first electrical connection portion 2 and the second electrical connection portion 3 are both used to electrically connect to the negative terminal of the battery (not shown in the figure), and the third electrical connection portion 4 is used to electrically connect to an electrical device (not shown in the figure). The first electrical connection portion 2 comprises a snap-in hole 21, a connecting section 22 and a mounting bolt 23, and the IBS is snap-fitted to the negative terminal of the battery through the snap-in hole 21, and then fixedly connected by the mounting bolt 23.

[0047] Adopting the above solution will bring the following technical problems:

[0048] ① Such as Figure 2As shown in the figure, the dotted line a represents the axis of the clamping hole 21. The IBS is clamped with the negative terminal of the battery through the clamping hole 21. At this time, the housing 1 extends out of the negative terminal of the battery. There is a connecting section 22 between the housing 1 and the first electrical connection part 2. When the vehicle is running, the vibration will cause fatigue damage to the connecting section 22, or even break, so that the IBS cannot work normally. To solve this problem, the solution adopted in the prior art is to strengthen the design of the connecting section 22, such as Figure 1 As shown, the arc-shaped connecting section 221 is designed to buffer vibration. In this way, due to the limitation of the processing technology, the processing difficulty of the IBS will be increased, and the production cost of the IBS will also be increased;

[0049] ② The installation environment of the negative terminal of different batteries is different. Therefore, if different types of batteries are to be adapted, the first electrical connection part 2 and even the entire IBS need to be adaptively designed according to the orientation and angle of the installation position of the negative terminal.

[0050] ③ The third electrical connection part 4 in the prior art is limited by the overall size requirements of the IBS and the space size requirements of the aforementioned installation position, and it is impossible to design a temperature measuring part. Therefore, the prior art estimates the battery temperature by setting a temperature sensor in the housing 1 and detecting the temperature of the PCB circuit board in the housing 1. Since the external environment has a greater impact on the PCB, the obtained battery temperature value is not accurate enough;

[0051] ④ The second electrical connection portion 3 needs to be connected to the housing 1 by welding, which results in poor connection stability, complex process and high cost.

[0060] In addition, since the first flexible electrical connection portion 20 and the second flexible electrical connection portion 30 are flexible, the arc-shaped transition section 304, the first straight section 303 and the second straight section 305 can be easily converted to each other to adapt to the spatial layout inside the vehicle.
