According to one embodiment, the battery protection circuit 252 is disposed on one side of the battery cell 251 and may be electrically connected to the negative tab 253b and the positive tab 253a protruding from the battery cell 251. For example, the battery protection circuit 252 may be formed to extend along the upper side of the battery cell 251 (eg, the side facing the main circuit board 301). The battery protection circuit 252 is a module for controlling and protecting the inside of the battery cell 251, and can prevent overcharging and/or overdischarging of the battery cell 251. The battery protection circuit 252 has a first side 252a facing the rear of the electronic device 101 (e.g., one side in the -Z-axis direction) and the first side 252a facing the front of the electronic device 101 (e.g., one side in the +Z-axis direction). It may include a second side 252b facing, and a side 252c facing the main circuit board 301.

According to one embodiment, the flexible circuit board 300 is disposed on one side of the battery protection circuit 252 (or battery cell 251), and is connected to the battery protection circuit 252 (or battery cell 251) and the main circuit board. (301) can be electrically connected. For example, at least a portion of the flexible circuit board 300 may be located between the battery protection circuit 252 and the main circuit board 301.

According to one embodiment, the flexible circuit board 300 may include a first end 330a, a first region 310, a second region 320, and a second end 330b. The first area 310 may be disposed along the side of the battery 250 (eg, battery protection circuit 252) facing the main circuit board 301. For example, the first area 310 may be in contact with the side surface 252c of the battery protection circuit 252 and may extend along a first direction (eg, X-axis direction). For example, the first area 310 may be spaced apart from the side surface 252c of the battery protection circuit 252 and may extend along a first direction (eg, X-axis direction). The second area 320 is arranged to face the main circuit board 301 from the first area 310 and extends in a second direction (e.g., Y-axis direction) different from the first direction (e.g., X-axis direction). can be placed.

According to one embodiment, the first end 330a of the flexible circuit board 300 extends from one end of the first area 310 and may contact the battery protection circuit 252 for electrical connection. The first end 330a may overlap a portion of the first surface 252a of the battery protection circuit 252.

According to one embodiment, the first end 330a of the flexible circuit board 300 is located in the center area of the first side 252a of the battery protection circuit 252 and extends toward the main circuit board 301. It can be. For example, the first end 330a is located between the positive electrode tab 253a and the negative electrode tab 253b of the battery cell 251, and at least a portion of the first area 310 extending from the first end 330a It may also be located between the anode tab 253a and the cathode tab 253b of the battery cell 251 (hereinafter referred to as front-drawn structure).

According to one embodiment, the second end 330b of the flexible circuit board 300 extends from one end of the second area 320 and may contact the main circuit board 301 for electrical connection. The second end 330b may overlap a portion of one side of the main circuit board 301 (eg, one side facing the -Z axis). A connecting member may be disposed at the second end 330b to be electrically connected to the main circuit board 301. The connection member may include, for example, at least one of a Con to Con connector, a clip type connector, a coaxial cable connector, or an interposer.

According to one embodiment, the first area 310 and the second area 320 of the flexible circuit board 300 may be arranged so as not to overlap. For example, the first direction (e.g., X-axis direction) in which the first area 310 extends and the second direction (e.g., Y-axis direction) in which the second area 320 extends may be substantially perpendicular. . For example, the first direction in which the first area 310 extends (e.g., X-axis direction) and the second direction in which the second area 320 extends (e.g., Y-axis direction) may be approximately 90 degrees or more. . However, it is not limited to this, and the design may be modified into various shapes that do not overlap each other (e.g., the flexible circuit board 300 is not bent approximately 180 degrees).

According to one embodiment, the first region 310 of the flexible circuit board 300 may extend along the +X-axis direction or may extend along the -X-axis direction. According to the front lead-out structure, the first end 330a may be located between the positive electrode tab 253a and the negative electrode tab 253b of the battery cell 251. For example, as the solder pad connecting the first end 330a and the battery protection circuit 252 is located near the center of the battery (e.g., between the positive tab 253a and the negative tab 253b) , the first area 310 extending from the first end 330a may be formed along the -X-axis direction or the +X-axis direction through design changes.

In general (e.g., see FIG. 5b for comparative example), when the flexible circuit board of the battery is formed in a structure that is drawn out from the side of the battery (hereinafter referred to as the side draw structure), a solder pad connecting the flexible circuit board and the battery protection circuit is used. (solder pad) Additionally, it may be a structure placed on the side of the battery. In this case, the wiring length of the flexible circuit board must be designed differently depending on the battery model, and as the wiring length changes (e.g. becomes longer), direct current resistance may increase, which may result in increased material costs and inconvenience in the design process. there is. The front drawing structure of the flexible circuit board 300 (300a) according to the present disclosure can be applied to various battery models by changing only a part of the structure of the flexible circuit board 300, thereby providing common use of battery parts.

According to one embodiment, the first area 310 of the flexible circuit board 300 may be formed to have a larger area than the second area 320. For example, the first area 310 extending along the side 252c of the battery protection circuit 252 is the second area 320 extending by the distance between the battery protection circuit 252 and the main circuit board 301. ) may have an area approximately 2 to 4 times larger than that of the area.

In general, the battery 250 may generate high heat due to the resistance component of the charging wiring during high-speed charging. For example, high heat is generated in the battery protection circuit 252 and the flexible circuit board 300 of the battery 250, and the flexible circuit board 300 is attached to the housing 201 (e.g., the back plate 280 of FIG. 9B). )), the surface temperature of the electronic device may increase.

According to one embodiment (see FIG. 5A), compared to the comparative example (see FIGS. 5B and 5C), the flexible circuit board 300 is designed so as not to overlap, so that the battery 250 and its surroundings (e.g., electronics) Heat generated from the surface of the device 101 can be reduced. In the comparative example, a lot of heat may be generated in area A of the flexible circuit board 303 of FIG. 5B because there are overlapping substrate areas. For example, when the current flowing through the charging wire of the flexible circuit board 303 of FIG. 5B during high-speed charging is approximately 9A, the area A may generate a current of approximately 18A due to the overlapping charging wires. Unlike the comparative example, the flexible circuit board 300 of FIG. 5A according to one embodiment includes a first region 310 and a second region 320 extending in a different direction from the first region 310. , the flexible circuit board 300 can be designed so that no overlapping areas occur in the entire area. Accordingly, heat generation performance according to dispersion of the heat source can be improved.

According to one embodiment (see FIG. 5A), compared to the comparative embodiment (see FIG. 5B), the overlapping area between the flexible circuit board 300 and other heat sources (e.g., the battery protection circuit 252) is reduced. It can be designed. Accordingly, heat generated in the battery 250 and its surroundings can be reduced. In the comparative example, the area B of the flexible circuit board 303 in FIG. 5B has a contact area with the battery protection circuit 252, which is one of the main heat sources, so that the area is relatively large compared to the flexible circuit board 300 in FIG. 5A. It is placed. As area B of the flexible circuit board 303 in FIG. 5B overlaps the battery protection circuit 252, a lot of heat may be generated. According to one embodiment, the first area 310 of the flexible circuit board 300 of FIG. 5A is in contact with the side 252c of the battery protection circuit 252, but the area of the first area 310 is smaller than that of FIG. 5B. By designing it to be approximately 1/2 to 3/4 smaller than the area B of the flexible circuit board 303, heat generation performance can be improved by dispersing the heat source.

According to one embodiment, the flexible circuit board 300 of FIG. 5A is designed so that the area of the first end 330a facing the -Z axis is relatively small compared to the area B of the flexible circuit board 303 of FIG. 5B. It can be. Accordingly, the overlap area between the housing disposed toward the -Z axis (e.g., the back plate 280 in FIG. 4b) and the flexible circuit board 300 is provided to be small, which may limit the increase in the surface temperature of the electronic device. You can. According to one embodiment (see FIG. 5A), compared to the comparative embodiment (see FIG. 5B), by reducing the length of the flexible circuit board 300, heat generated in and around the battery 250 can be reduced. You can. In the comparative example, the flexible circuit board 303 of FIG. 5B is arranged to have a relatively longer length than the flexible circuit board 300 of FIG. 5A. As the length of the flexible circuit board increases, the direct current resistance (DCR) increases and the heat generation of the flexible circuit board may increase due to increased power loss. According to one embodiment, the length of the flexible circuit board 300 in FIG. 5A is designed to be approximately 1/2 or less compared to the length of the flexible circuit board 303 in FIG. 5B, thereby reducing heat generation of the circuit board itself. Heat generation performance can be improved.

According to one embodiment (see FIG. 5A), compared to the comparative example (see FIG. 5C), a circuit board with increased layers can be provided by reducing the bending angle of the flexible circuit board 300. Generally, for ultra-fast charging of 45W or more, the maximum charge current of the battery must be designed to be 10A or more. To achieve this, the width of the flexible circuit board must be expanded or the layers of the board must be increased from 2 to 3 layers or more (e.g. : It must be increased to 4 layers. In a comparative example, region C of the flexible circuit board 304 of FIG. 5C is in the shape of a circuit board that is sharply bent due to a configuration of substrates overlapping each other (e.g., a configuration in which some regions are bent to face each other), and has three or more layers. It is difficult to provide laminated layers and cannot form wiring for ultra-fast charging. According to one embodiment, the first region 310 extending in the first direction (e.g., X-axis direction) and the second region 310 extending in the second direction (e.g., Y-axis direction) of the flexible circuit board 300 of FIG. 5A The second region 320 may be formed substantially vertically or may be formed at a bending angle of 90 degrees or more. By constructing the flexible circuit board 300 that does not bend sharply, it is possible to form a circuit board with three or more layers (e.g., four layers) that allows for free design of the number of layers and enables fast charging. However, the flexible circuit board 300 according to the present disclosure is not limited to a design with three or more layers, and can provide a battery charging path through a two-layer design for 15W/25W charging.
