[0048] Figure 1 is a perspective view of a battery heating device according to some embodiments.

[0049] Referring to Figure 1 , a battery heating device 1 according to some embodiments may include a lower plate 2 and a support module 40. The support module 40 may be disposed on the lower plate 2 in the z-axis direction. The support module 40 may be fixed to the lower plate 2. The support module 40 may be maintained horizontal with respect to the ground on the lower plate 2 (e.g., a plane defined by the x-axis direction and the y-axis direction). The lower plate 2 may be formed such that the support module 40 is maintained horizontal with respect to the ground. The support module 40 may be maintained horizontal with respect to the ground such that the support module 40 stably accommodates the cylindrical battery 10 (e.g., as described with respect to Figure 2 ). The support module 40 may be maintained horizontal with respect to the ground such that the axis of the cylindrical battery 10 inserted into the support module 40 is positioned perpendicular to the ground. However, the arrangement of the support module 40 and the lower plate 2 is not limited to the foregoing description.

Figure 3 is an exploded view of a battery heating device 1 according to some embodiments. Figure 4 is Figure 1 a partial cross-sectional perspective view of a cross-section A - A' of the battery heating device 1 of

[0051] Referring to Figures 1 to 4, According to some embodiments, the cylindrical battery 10 can be inserted into the battery heating device 1. The cylindrical battery 10 can be received in the battery heating device 1. The cylindrical battery 10 can be provided in plurality. Each of the plurality of cylindrical batteries 10 can be inserted into the battery heating device 1. Each of the plurality of cylindrical batteries 10 can be received in the battery heating device 1.

[0052] According to some embodiments, each of the plurality of cylindrical batteries 10 can be inserted into the support module 40. Each of the plurality of cylindrical batteries 10 can be received in the battery heating device 1. In the following description, unless explicitly described as plural, the cylindrical battery 10 can mean a single cylindrical battery 10 or a plurality of cylindrical batteries 10 according to the context.

[0053] The support module 40 according to an embodiment can include a first module 41. The first module 41 can receive the cylindrical battery 10. Each cylindrical battery 10 can be received in the first module 41. The first module 41 can include a plurality of receiving spaces 410. Each cylindrical battery 10 can be received in the receiving space 410 of the first module 41. The cylindrical battery 10 can be supported by the first module 41 in the receiving space 410.

[0054] According to some embodiments, the receiving space 410 of the first module 41 can be formed to surround at least a part of each cylindrical battery 10. The receiving space 410 of the first module 41 can be formed to cover at least a part of the outer circumferential surface of the cylindrical battery 10. The receiving space 410 of the first module 41 can be formed to be larger than the outer circumference of the cylindrical battery 10. The side wall 4100 of the receiving space 410 defining the receiving space 410 can be formed to follow at least a part of the outer circumferential surface of the cylindrical battery 10. The side wall 4100 of the receiving space 410 can be formed to be spaced apart from the outer circumferential surface of the cylindrical battery 10 by a predetermined gap. The cylindrical battery 10 can not directly contact the side wall 4100 of the receiving space 410 in the receiving space 410 of the first module 41. Specific details about this will be described later.

[0055] According to some embodiments, the first module 41 can include a plurality of openings 411 provided to allow the cylindrical battery 10 to be inserted therein. In the following description, according to the context, the opening 411 can mean a single opening 411 or a plurality of openings 411.

[0056] According to some embodiments, the opening 411 of the first module 41 may be formed in the upper part of the accommodation space 410 of the first module 41. The opening 411 may be formed in a circular shape. If the opening 411 is formed in a circular shape, the opening 411 viewed from a top view may be circular. Each cylindrical battery 10 may be inserted into the accommodation space 410 through the opening 411 of the first module 41. If the cylindrical battery 10 is inserted through the opening 411, the cylindrical battery 10 may be inserted into the opening 411 through a member other than the first module 41. For example, the cylindrical battery 10 may be inserted into the opening 411 of the first module 41 through the second module 42 described below. However, the above description of the manner in which the cylindrical battery 10 is accommodated in the accommodation space 410 may be merely an exemplary description, and the present disclosure is not limited thereto.

[0057] According to some embodiments, the support module 40 may include a second module 42. The second module 42 may be disposed on the first module 41. The first module 41 may be disposed below the second module 42.

[0058] According to some embodiments, the second module 42 may adjust the position where the cylindrical battery 10 is accommodated in the first module 41. The second module 42 may be used to adjust the position where the cylindrical battery 10 is accommodated in the accommodation space 410 of the first module 41. The second module 42 may be used to adjust the position where the cylindrical battery 10 is inserted into the opening 411 of the first module 41. The position where each cylindrical battery 10 is accommodated in the first module 41 may be adjusted by the second module 42. The position where each cylindrical battery 10 is accommodated in the accommodation space 410 of the first module 41 may be adjusted by the second module 42. The position where each cylindrical battery 10 is inserted into the opening 411 of the first module 41 may be adjusted by the second module 42.

[0059] If the position where the cylindrical battery 10 is accommodated is adjusted, each cylindrical battery 10 may be accommodated to avoid being biased to one side in the accommodation space 410 of the first module 41. If the position where the cylindrical battery 10 is accommodated is adjusted, each cylindrical battery 10 may be arranged to be spaced apart from the side wall 4100 of the accommodation space 410 by a predetermined space in the accommodation space 410 of the first module 41. If the position where the cylindrical battery 10 is accommodated is adjusted, each cylindrical battery 10 may be arranged in the central portion of the accommodation space 410 of the first module 41. If the position where the cylindrical battery 10 is accommodated is adjusted, each cylindrical battery 10 may not directly contact the side wall 4100 of the accommodation space 410 of the first module 41. However, the function of the second module 42 is not limited to the foregoing description.

[0060] According to some embodiments, the second module 42 may include a plurality of penetration portions 421. In the following description, depending on the context, the penetration portion 421 may refer to a single penetration portion 421 or a plurality of penetration portions 421. The penetration portion 421 may be an area where the cylindrical battery 10 is inserted in the direction of the second module 42. The penetration portion 421 may be an area where the cylindrical battery 10 penetrates the top surface and the bottom surface of the second module 42 toward the first module 41. Each penetration portion 421 may correspond to the opening 411 of the first module 41. The penetration portion 421 may be formed in a circular shape. If the penetration portion 421 is formed in a circular shape, the penetration portion 421 viewed from a top view may be circular. The side surface of each penetration portion 421 may correspond to the side wall 4100 of the accommodation space 410 of the first module 41.

[0061] According to some embodiments, the penetration portion 421 may be used to adjust the position of the cylindrical battery 10 accommodated in the first module 41. The penetration portion 421 may be used to adjust the position of the cylindrical battery 10 accommodated in the accommodation space 410 of the first module 41. The penetration portion 421 may be used to adjust the position of the cylindrical battery 10 inserted into the opening 411 of the first module 41. The position of each cylindrical battery 10 accommodated in the first module 41 may be adjusted by the penetration portion 421. The position of each cylindrical battery 10 accommodated in the accommodation space 410 of the first module 41 may be adjusted by the penetration portion 421. The position of each cylindrical battery 10 inserted into the opening 411 of the first module 41 may be adjusted by the penetration portion 421.

[0062] According to some embodiments, the penetration portion 421 applicable to the second module 42 may have various shapes. The shape of the penetration portion 421 may be defined according to the shape of the cylindrical battery 10 inserted into the penetration portion 421. For example, if the diameter of the cylindrical battery 10 inserted into the support module 40 is large, the diameter of the penetration portion 421 may be formed large. For example, if the diameter of the cylindrical battery 10 inserted into the support module 40 is small, the diameter of the penetration portion 421 may be formed small. For example, if the length of the cylindrical battery 10 inserted into the support module 40 is long, the penetration length of the penetration portion 421 may be formed long. For example, if the length of the cylindrical battery 10 inserted into the support module 40 is short, the penetration length of the penetration portion 421 may be formed short. That is to say, the penetration portion 421 having different shapes according to the shape of the cylindrical battery 10 may be applied. That is to say, the second module 42 including the penetration portion 421 having different shapes according to the shape of the cylindrical battery 10 may be applied. However, the relationship between the shape of the cylindrical battery 10 and the penetration portion 421 of the second module 42 is not limited to the foregoing description. For example, if the length of the cylindrical battery 10 is long, the second module 42 having the penetration portions 421 with the same shape may be arranged on the first module 41.

[0063] In some embodiments, the second module 42 arranged on the first module 41 can be replaced according to the shape of the cylindrical battery 10 inserted into the battery heating device 1. That is to say, the second module 42 including a penetration part 421 having different shapes according to the shape of the cylindrical battery 10 can be applied.

[0064] According to some embodiments, the first module 41 and the second module 42 can include a fixing element 51. The fixing element 51 can be configured to fix the relative positions of the first module 41 and the second module 42. The fixing element 51 can fix the position of the penetration part 421 of the second module 42 to the opening 411 of the first module 41. The fixing element 51 can be configured to fix the penetration part 421 to a position corresponding to the opening 411. If the penetration part 421 is fixed to a position corresponding to the opening 411, the position where the cylindrical battery 10 is inserted into the opening 411 of the first module 41 can be adjusted. If the penetration part 421 is fixed to a position corresponding to the opening 411, the position where the cylindrical battery 10 is inserted into the accommodation space 410 of the first module 41 can be adjusted.

[0065] Even if the second module 42 arranged on the first module 41 is replaced according to the shape of the cylindrical battery 10, the fixing element 51 can fix each penetration part 421 to a position corresponding to the opening 411. For example, any one of the fixing element 51 of the first module 41 and the fixing element 51 of the second module 42 can be in the form of a protrusion, while the other can be in the form of a groove. For example, the fixing element 51 in the first module 41 and the fixing element 51 in the second module 42 can be arranged symmetrically with respect to each other. However, the functions and shapes of the fixing element 51 are examples and are not limited to the foregoing description.

[0066] The second module 42 can be configured such that the penetration part 421 adjusts the position where the cylindrical battery 10 is accommodated in the accommodation space 410 of the first module 41. A detailed description of the support module 40 including the first module 41 and the second module 42 to adjust the position where the cylindrical battery 10 is accommodated will be described later.

[0067] In some embodiments, the battery heating device 1 can include a heating element 3. The heating element 3 can be configured to heat the cylindrical battery 10 accommodated in the battery heating device 1. The cylindrical battery 10 can be heated by the heating element 3. The heating of the cylindrical battery 10 can be at least a part of the manufacturing process of the cylindrical battery 10. The heating of the cylindrical battery 10 can be at least a part of the activation process of the secondary battery.

[0068] According to some embodiments, the heating element 3 may be between the lower plate 2 and the support module 40. The heating element 3 may be disposed on the lower plate 2. The heating element 3 may be disposed below the support module 40. The lower plate 2, the heating element 3, and the support module 40 may be sequentially disposed from the ground. If the heating element 3 is disposed below the support module 40, the heating element 3 may transfer heat well to the support module 40. If the heating element 3 is disposed on the lower plate 2, the heat emitted from the heating element 3 may be well transferred to the support module 40. However, this arrangement of the heating element 3, the lower plate 2, and the support module 40 is an example, and the present disclosure is not limited thereto.

[0069] The heat emitted from the heating element 3 may heat the support module 40. The support module 40 may transfer the heat emitted from the heating element 3 to the cylindrical battery 10. The heating element 3 may heat the cylindrical battery 10 through the support module 40. The heating element 3 may heat the first module 41. The heating element 3 may heat the accommodation space 410 of the first module 41. The heating element 3 may heat the cylindrical battery 10 accommodated in the first module 41. The heating element 3 may heat the cylindrical battery 10 accommodated in the accommodation space 410 of the first module 41. However, the function of the heating element 3 is not limited to the foregoing description.

[0070] The heating element 3 may heat a plurality of cylindrical batteries 10 simultaneously. Each of the plurality of cylindrical batteries 10 accommodated in the support module 40 may be heated by the heating element 3 simultaneously. The heating element 3 may heat each of the plurality of cylindrical batteries 10 evenly. The heating element 3 may transfer heat evenly to each of the plurality of cylindrical batteries 10. If the heating element 3 heats each of the plurality of cylindrical batteries 10 simultaneously, it may mean that the support module 40 heated by the heating element 3 heats each of the plurality of cylindrical batteries 10 simultaneously. If the heating element 3 heats each of the plurality of cylindrical batteries 10, it may mean that the first module 41 heated by the heating element 3 heats each of the plurality of cylindrical batteries 10. However, the scheme for the heating element 3 to heat each of the plurality of cylindrical batteries 10 is not limited to the foregoing description. For example, the heating element 3 may heat the plurality of cylindrical batteries 10 in a form that transfers radiant heat to each of the plurality of cylindrical batteries 10 without using the first module 41.

[0071] The heating element 3 can be configured to transfer uniform heat to a plurality of accommodation spaces 410 included in the support module 40. For example, the heating element 3 can be uniformly arranged under the support module 40 to correspond to each of the plurality of accommodation spaces 410 of the support module 40. If the heating element 3 is uniformly arranged under the support module 40, it can mean that the heat transfer rate per unit area from the heating element 3 towards the bottom of the support module 40 is the same. For example, the heating element 3 can be a heater in the form of a plate arranged under the support module 40. For example, the heating element 3 can include a plurality of heating elements arranged under the support module 40 with a uniform density. However, the shape of the heating element 3 is not limited to the foregoing description. For example, the heating element 3 can be a heat medium flowing at the same flow rate per unit area under the support module 40.

[0072] According to some embodiments, the first module 41 can receive the heat emitted from the heating element 3. The first module 41 can be in direct contact with the heating element 3. The heating element 3 can transfer heat to the first module 41 in a heat conduction manner. If the first module 41 receives heat from the heating element 3 in a heat conduction manner, the first module 41 can effectively receive the heat emitted from the heating element 3. The first module 41 can include a metallic material. If the first module 41 includes a metallic material, the first module 41 can receive the heat emitted from the heating element 3 well. However, the material and components of the first module 41 are not limited to the foregoing description. The manner in which the first module 41 receives heat from the heating element 3 is not limited to the foregoing description.

[0073] Figure 5 is a perspective view of a battery heating device including a plurality of support modules according to some embodiments.

[0074] Referring to Figures 1 to 5 , according to some embodiments, the battery heating device 1a can include a plurality of support modules 40. The support modules 40 can be provided in plurality. Each of the plurality of support modules 40 can be arranged on the lower plate 2. The heating element 3 can be between the plurality of support modules 40 and the lower plate 2. The number of support modules 40 included in the battery heating device 1a can be adjusted according to the number of cylindrical batteries 10 inserted into the battery heating device 1a. For example, if additional accommodation spaces 410 for accommodating the cylindrical batteries 10 are needed, the cylindrical batteries 10 can be further accommodated by adding support modules 40 to the battery heating device 1a. Adding support modules 40 to the battery heating device 1a can include adding support modules 40 to an area of the lower plate 2 where no support module 40 is arranged. Although not shown, adding support modules 40 to the battery heating device 1a can include further arranging separate support modules 40 on the support modules 40. However, the number of support modules 40 and their arrangement are not limited to the foregoing description.

[0076] Refer to Figures 2 to 6 , according to some embodiments, the opening 411 of the first module 41 and the through hole 421 of the second module 42 may have the same central axis C. The through hole 421 of the second module 42 may be arranged to have the same central axis corresponding to the opening 411 of the first module 41. If the opening 411 of the first module 41 and the through hole 421 of the second module 42 have the same central axis, the position of the cylindrical battery 10 inserted into the opening 411 of the first module 41 through the through hole 421 of the second module 42 can be adjusted. If the opening 411 of the first module 41 and the through hole 421 of the second module 42 have the same central axis, the position of the cylindrical battery 10 accommodated in the accommodation space 410 of the first module 41 can be adjusted.

[0077] Figure 7 Shows Figure 6 A cross-sectional view of the through hole formed in the battery heating device shown in
