Definitions
- the present invention relates to the structure of a battery pack comprising a thermally conductive resin. More specifically, the present invention relates to the structure of a battery pack having improved bonding strength and thermal conductivity between a thermally conductive resin provided between a battery module and a pack frame and a module frame.
- Secondary batteries which boast high electrical properties such as high energy density and easy applicability across a wide range of product groups, are widely used not only in portable devices but also in electric or hybrid vehicles powered by electrical power sources, as well as in power storage devices. These batteries are attracting attention as a new energy source for environmental friendliness and energy efficiency, not only because they can dramatically reduce fossil fuel use, but also because they produce no byproducts from energy use.
- While small mobile devices typically use one or two or three battery cells per device, medium- to large-sized devices, such as automobiles, require high output and large capacity. Therefore, medium- to large-sized battery modules, which electrically connect multiple battery cells, are used. Furthermore, these battery modules can be integrated into battery packs to achieve even higher output and capacity.
- FIG. 1 illustrates a battery pack.
- the battery pack (P) is configured to include a plurality of battery modules (M) and a pack frame (PF) that accommodates the battery modules.
- the battery modules (M) are electrically connected to each other to form a single high-capacity, high-voltage battery.
- the thermally conductive resin (3) also serves to adhesively fix the battery module (M) and the pack frame (PF).
- this type of fixation relies solely on the adhesive strength between the module frame (20) and the pack frame (PF) and the thermally conductive resin (3), it is very vulnerable to loads that cause slippage.
- the present invention was created under the background of the above-described prior art, and its purpose is to provide a structure of a battery pack in which heat generated from a battery module can be dissipated to the outside through a pack frame.
- the present invention seeks to provide a structure of a battery pack in which the bonding force between the thermally conductive resin and the module frame is strengthened, so that the mechanical fixation between the module frame and the thermally conductive resin and/or the thermal connection between the battery module and the pack frame can be firmly maintained.
- the present invention seeks to provide a structure of a battery pack in which horizontal and/or vertical detachment of a thermally conductive resin from a module frame is prevented.
- the present invention provides a battery pack structure including: a battery module having a module frame; a pack frame having a bottom plate on which the battery module is mounted; and a thermally conductive resin interposed between the bottom plate of the battery module and the bottom plate of the pack frame; wherein a hole-shaped anchor portion is provided in the bottom plate of the module frame, and the thermally conductive resin has an extension portion that extends upward and fills the anchor portion.
- the thermally conductive resin can resist a shear load occurring between the bottom plate of the module frame and the thermally conductive resin, and the thermally conductive resin can be prevented from horizontally detaching from the module frame.
- the anchor portions may be arranged in a grid of three or more rows and three or more columns. Furthermore, the rows and columns of the anchor portions may be arranged at equal intervals. Accordingly, each anchor portion may evenly distribute shear stress, and heat may be evenly dissipated through the thermally conductive resin.
- the anchor portion may include a first portion having a circular cross-section of a predetermined first inner diameter, and a second portion having a circular cross-section of a predetermined second inner diameter larger than the first inner diameter and positioned above the first portion.
- the first part may have a rectangular cross-section extending along one horizontal direction with a predetermined width and length
- the second part may have a rectangular cross-section extending along another horizontal direction intersecting the one horizontal direction with the predetermined width and length.
- the above anchor portion may include a tapered portion whose cross-sectional area becomes narrower as it goes downward.
- the tapered portion may prevent the thermally conductive resin from falling downward from the module frame by interfering with the extension portion from below.
- the anchor portion may include a tapered portion having a circular cross-section whose inner diameter becomes smaller as it goes downward.
- the anchor portion may include a tapered portion having an inner circumferential surface in the shape of a truncated cone whose inner diameter becomes smaller as it goes downward.
- the thermally conductive resin may include: an upper resin layer connected to the upper portion of the bottom plate of the module frame; and a lower resin layer connected to the lower portion of the bottom plate of the module frame.
- the extension portion may connect the upper resin layer and the lower resin layer via the anchor portion.
- the upper resin layer may interfere with the bottom plate of the module frame from below, thereby preventing the entire thermally conductive resin from falling off downward from the bottom plate of the module frame.
- the thermally conductive resin may connect the upper and lower portions of the bottom plate of the module frame, thereby more effectively dissipating heat generated from a battery cell mounted on the module frame to the outside of the module frame.
- the present invention also provides a battery pack structure comprising: a battery module having a module frame; a pack frame having a bottom plate on which the battery module is mounted; and a thermally conductive resin interposed between the bottom plate of the battery module and the bottom plate of the pack frame; wherein the bottom plate of the battery module has an anchor portion in the shape of a groove sunken upward, and the thermally conductive resin has an extension portion that extends upward and fills the anchor portion.
- the thermally conductive resin can resist a shear load occurring between the bottom plate of the module frame and the thermally conductive resin, and the thermally conductive resin can be prevented from horizontally detaching from the module frame.
- the contact area between the thermally conductive resin and the module frame increases, the speed at which heat is conducted from the thermally conductive resin to the pack frame increases.
- the anchor portions may be arranged in multiple rows that extend parallel to each other and are arranged in parallel. Furthermore, the multiple rows of anchor portions may be arranged at equal intervals. Accordingly, each anchor portion can evenly distribute shear stress, and heat dissipation through the thermally conductive resin can occur evenly.
- the anchor portion may include a first portion having a predetermined first internal width along a horizontal direction, and a second portion having a predetermined second internal width greater than the first internal width along the horizontal direction and positioned above the first portion.
- the anchor portion may include the first portion and a second portion positioned above the first portion, and the cross-sectional shape of the first portion may not completely include the cross-sectional shape of the second portion in a plan view. Accordingly, the extension portion may interfere from below between the first portion and the second portion, and the thermally conductive resin may be prevented from falling off downward from the floor plate.
- the anchor portion may include a first portion having a rectangular cross-section extending along a longitudinal direction to a predetermined first inner width, and a second portion having a rectangular cross-section extending along a longitudinal direction to a predetermined second inner width greater than the first inner width, and positioned lower than the first portion.
- the anchor portion may include a tapered portion whose cross-sectional area becomes narrower as it goes downward.
- the tapered portion may prevent the thermally conductive resin from falling upward from the bottom plate of the module frame by interfering with the extension portion from below.
- the anchor portion may include a tapered portion extending in the longitudinal direction and having a trapezoidal cross-section with an upper width greater than a lower width in the longitudinal direction.

- the battery pack may be installed in the vehicle as a power source.
- the vehicle may be an electric vehicle or a hybrid vehicle.
- the vehicle may be a two-wheeled vehicle or a four-wheeled vehicle.
- the structure of the vehicle is not limited to the above, and the battery pack need not necessarily serve as the vehicle's power source.
- the present invention can provide a structure of a battery pack in which heat generated from a battery module can be dissipated to the outside of the pack frame by thermally connecting the battery module and the pack frame by a thermally conductive resin.
- the present invention can provide a structure of a battery pack in which the bonding force between the thermally conductive resin and the module frame is strengthened, so that the mechanical fixation between the module frame and the thermally conductive resin and the thermal connection between the battery module and the pack frame can be firmly maintained.
- the present invention can provide a structure of a battery pack in which horizontal detachment of a thermally conductive resin from a module frame is prevented due to interference between a downward extension of the thermally conductive resin and an anchor portion, and a structure of a battery pack in which vertical detachment of the thermally conductive resin from the module frame is prevented due to a cross-sectional shape of the anchor portion.
