Description

Technical Field

[0001] The utility model relates to a battery accommodating shell. Background Art

[0002] Patent Document 1 describes a housing comprising a container, a gas adsorption unit, and a first valve. The container houses items, the gas adsorption unit comprises an adsorbent material capable of adsorbing gas generated within the container, and the first valve discharges a first gas from the gas adsorption unit to the exterior of the housing. This technology improves safety by reducing the first gas's concentration in the gas adsorption unit before discharging it from the first valve.

[0004] The technology of Patent Document 1 cannot detect a decrease in the adsorption performance of the adsorbent material due to aging or the like. Utility Model Content

[0005] The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a battery housing case capable of detecting degradation in the performance of an adsorbent.

[0006] The utility model relates to a battery housing shell, which comprises: a first outer shell for housing a battery, an adsorbent material for adsorbing gas generated from the battery being adhered to the inner side thereof, and fine holes formed therein for allowing the gas to pass through; a second outer shell for housing the first outer shell; and a detection unit, which is arranged between the first outer shell and the second outer shell and detects the gas.

[0007] According to the present invention, a battery housing case capable of detecting degradation in the performance of an adsorbent can be realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a diagram showing a schematic configuration of a battery housing case according to an embodiment. DETAILED DESCRIPTION

[0009] The battery housing case according to the embodiment of the present invention will be described with reference to the accompanying drawings. Components in the following embodiments include those that are easily replaceable by those skilled in the art or are substantially the same.

[0010] Figure 1 1 is a diagram showing a schematic structure of a battery housing case according to an embodiment. Figure 1 As shown, the battery housing case 1 includes a first outer case 3 housing the battery 2 , a second outer case 4 housing the first outer case, and a detection unit 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 any shape is not particularly limited as long as it is a battery. In addition, the number of batteries 2 is not particularly limited. Gases such as CO or CO2 may be generated from the battery 2 due to overcharging or the like.

[0012] The first outer casing 3 houses the battery 2 and has an adsorbent material attached to its interior to absorb the gas generated from the battery 2. The first outer casing 3 has pores formed therein to allow the gas to pass through. The first outer casing 3 is made of a material that is impermeable to the gas generated from the battery 2 and has a sheet of adsorbent material attached to its interior.

[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 gas generated from the battery 2 .

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

[0016] Those skilled in the art will readily derive further effects and variations. Therefore, the broader aspects of the present invention are not limited to the specific details and representative embodiments shown and described above. Therefore, various modifications may be made without departing from the spirit or scope of the general concept of the invention as defined by the technical solutions and their equivalents.

Claims

1. A battery housing, characterized in that: have: a first outer casing housing a battery, having an adsorbent material attached to the inner side thereof for adsorbing gas generated from the battery and having pores formed therein for allowing the gas to pass through; a second outer shell, accommodating the first outer shell; and The detection unit is disposed between the first outer casing and the second outer casing and detects the gas.
