[0031] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are 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.

[0032] In the description of the present application, it should be noted that the terms used herein are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but in appropriate cases, the techniques, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0033] Embodiment 1:

[0034] This embodiment provides a battery housing with a visible filling height, comprising:

[0035] A housing 1, wherein the housing 1 is provided with a connection hole 11 which is connected to the interior of the housing 1;

[0036] A visual liquid level tube 2, one end of which is detachably connected to the connection hole 11 and communicates with the interior of the housing 1, and the other end of which is provided with a blocking member 3;

[0037] It also includes a plug 4 , which is installed on the shell 1 to block the connecting hole 11 when the visual liquid level tube 2 is not installed on the shell 1 .

[0038] In the present technical solution, a connection hole 11 connected to the interior of the shell 1 is opened on one side of the battery shell 1, and the connection hole 11 is located close to the bottom of the shell 1. The plug 4 is adapted to the structure of the connection hole 11. When the plug 4 is installed on the connection hole 11, the connection hole 11 can be sealed to prevent the electrolyte from leaking from the connection hole 11 when the battery is filled with liquid.

[0039] When the visual liquid level tube 2 is used to detect the filling height inside the battery, the plug 4 is first installed at the connection hole 11, and the liquid is injected into the battery through the injection hole on the battery. After the injection is completed, the injection hole is sealed by setting a glue nail. Figure 4As shown, first place the battery on its side with the connection hole 11 of the battery facing upward, remove the plug 4, and then seal the end of the visual liquid level tube 2 connected to the connection hole 11 to the connection hole 11, and then realign the battery so that the electrolyte in the battery can flow into the visual liquid level tube 2 through the connection hole 11, and finally remove the sealing piece 3 on the other end of the visual liquid level tube 2 and the rubber nail on the filling hole, so that the liquid height in the visual liquid level tube 2 is flush with the liquid height inside the battery, thereby realizing the liquid level height detection after the battery is filled.

[0040] It is worth mentioning that the internal volume of the visual liquid level tube 2 is small, and the effect of the liquid flowing from the battery into the visual liquid level tube 2 on the filling height is negligible. In addition, the visual liquid level tube 2 can be directly installed and connected to the connection hole 11 of the housing 1. During the filling process, the visual liquid level tube 2 can synchronously display the filling height in the battery, which is practical and convenient.

[0041] After the liquid level detection is completed, you can continue as follows Figure 4 As shown, the battery is first placed on its side, and the visual liquid level tube 2 can be removed, so as not to affect the subsequent assembly of the battery in the module or battery pack.

[0042] In summary, by installing and connecting the detachable visual liquid level tube 2 on the side of the battery housing 1, the detection of the liquid filling height inside the battery and the visual observation of the liquid level change inside the battery are realized, which is highly practical.
