Description

[Technical field]

[0001] The present disclosure relates to a battery housing. [Background technology]

[0002] Patent Document 1 describes a storage case that includes a storage section in which an article is stored, a gas adsorption section having an adsorbent capable of adsorbing gas generated inside the storage section, and a first valve that discharges a first gas from the gas adsorption section to the outside of the storage case. This technology improves safety by reducing the concentration of the first gas by the gas adsorption section before discharging it from the first valve. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2022-181123 A Summary of the Invention [Problem to be solved by the invention]

[0004] The technique of Patent Document 1 cannot detect the deterioration of the adsorbent's adsorption performance due to aging or the like.

[0005] The present disclosure has been made in view of the above, and has an object to provide a battery housing case that is capable of detecting a decrease in the performance of an adsorbent. [Means for solving the problem]

[0006] The battery housing case of the present disclosure comprises a first outer case that houses a battery and has an adsorbent material attached to the inside that adsorbs gas generated by the battery and has pores through which the gas can pass, a second outer case that houses the first outer case, and a detection unit that is disposed between the first outer case and the second outer case and detects the gas. Effect of the Invention

[0007] According to the present disclosure, it is possible to realize a battery housing case capable of detecting a decrease in the performance of an adsorbent. [Brief description of the drawings]

[0008] [Figure 1] FIG. 1 is a diagram showing a schematic configuration of a battery housing case according to an embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] A battery housing case according to an embodiment of the present disclosure will be described with reference to the drawings. Note that components in the following embodiments include those that are easily replaceable by a person skilled in the art, or those that are substantially the same.

[0010] (Embodiment) Fig. 1 is a diagram showing a schematic configuration of a battery housing case according to an embodiment. As shown in Fig. 1, the battery housing case 1 includes a first outer case 3 that houses a battery 2, a second outer case 4 that houses the first outer case 3, and a detector 5 disposed between the first outer case 3 and the second outer case 4.

[0011] The battery 2 is, for example, a battery cell, but there is no particular limitation on the shape as long as it is a battery. There is also no particular limitation on the number of batteries 2. Gas such as CO or CO2 may be generated from the battery 2 due to overcharging or the like.

[0012] The first exterior case 3 houses the battery 2, has an adsorbent attached to its inside that adsorbs the gas generated from the battery 2, and has pores that allow the gas to pass through. The first exterior case 3 is made of a material that is impermeable to the gas generated from the battery 2, and has a sheet-like adsorbent attached to its inside.

[0013] The second outer case 4 houses the first outer case 3. The second outer case 4 is made of a material that is impermeable to gas generated from the battery 2.

[0014] The detection unit 5 is disposed between the first outer case 3 and the second outer case 4 , and detects the gas generated from the battery 2 .

[0015] According to the battery housing case 1 described above, gas that has not been completely adsorbed inside the first outer case 3 is discharged through the pores into the second outer case 4 and detected by the detection unit 5, making it possible to detect a deterioration in the performance of the adsorbent.

[0016] Further advantages and modifications may readily occur to those skilled in the art. Thus, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and equivalents thereof.
