Description

Transporting Jig for Battery Cell Units The present invention relates to a fixing jig for transporting battery cell units that can minimize various risks that may occur when transporting battery cell units. Unlike primary batteries, secondary batteries can be charged and discharged multiple times. Secondary batteries are widely used as energy sources for various wireless devices such as handsets, laptops, and cordless vacuum cleaners. Recently, as energy density has improved, capacity has increased, and economies of scale have been realized, the manufacturing cost per unit capacity of secondary batteries has decreased dramatically, and as the driving range of BEVs (Battery Electric Vehicles) has increased to a level equivalent to that of fuel vehicles, the primary use of secondary batteries is shifting from mobile devices to mobility. As the customer base for secondary batteries diversifies, there are cases where customers request that manufacturers supply battery cell units rather than finished battery packs to increase design flexibility. To supply batteries in the form of unit cells, they must pass UN38.3 certification. UN38.3 is a United Nations (UN) regulation designed to evaluate the safety of batteries. This regulation is one of the standards that must be strictly adhered to when transporting batteries worldwide and applies primarily to lithium batteries. As UN38.3 certification guarantees that batteries can be transported safely under specific conditions, secondary battery manufacturers need to demonstrate through this certification that their batteries meet internationally recognized safety standards. Therefore, even when transporting battery cell units rather than battery packs, UN38.3 certification must be passed; however, currently, it is difficult to pass the certification because there is no separate transport structure capable of pressurizing or protecting battery cell units. The following drawings attached to this specification illustrate preferred embodiments of the present invention and serve to further enhance understanding of the technical concept of the present invention together with the detailed description of the invention provided below; therefore, the present invention should not be interpreted as being limited only to the matters described in such drawings. FIG. 1 is a perspective view of a fixing jig for transporting a battery cell unit according to one embodiment of the present invention. FIG. 2 is an exploded perspective view of the fixing jig for transporting the battery cell unit of FIG. 1. FIG. 3 is a cross-sectional view cut along the line "AA" in FIG. 1. FIGS. 4 to 7 are drawings illustrating a series of processes for housing a battery cell unit in a fixed jig for transporting a battery cell unit. The present invention is capable of various modifications and may have various embodiments, and specific embodiments are to be described in detail below. However, this is not intended to limit the invention to specific embodiments, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. In the present invention, terms such as "comprising" or "having" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not excluding in advance the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Furthermore, in the present invention, when a part such as a layer, film, region, or plate is described as being "on" another part, this includes not only cases where it is "immediately above" the other part, but also cases where there is another part in between. Conversely, when a part such as a layer, film, region, or plate is described as being "under" another part, this includes not only cases where it is "immediately below" the other part, but also cases where there is another part in between. Additionally, in the present application, being "placed on" may include cases where it is placed on the lower part as well as on the upper part.
