[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. (First embodiment)

[0011] FIG. 1 is a diagram showing a first embodiment of a charging system of the present invention. As shown in FIG. 1, the charging system in this embodiment is mounted on a vehicle 1, and includes a battery 100, a charger 200, and a fixing member 210. FIGS. 2a to 2c are diagrams showing an example of a manner in which the charger 200 is fixed to the battery 100 shown in FIG. 1. FIGS. 2a to 2c show a charging system 10 in this embodiment. Note that the vehicle 1 may be not only a passenger car, but also automobiles such as buses and trucks, special-purpose vehicles such as bulldozers and forklifts, agricultural vehicles such as tractors, motorcycles, motorbikes, electric wheelchairs, go-karts, and the like. The type of vehicle 1 is not limited to these.

[0012] The battery 100 is a general vehicle-mounted battery that supplies electric current (power) to an electrical system equipped in the vehicle 1. The battery 100 is fixed to the vehicle 1. The battery 100 is charged by storing electricity generated by a generator that operates using engine rotation while the engine of the vehicle 1 is running. The battery 100 can also be charged from the outside. The battery 100 has various sizes. For example, the size of the short side of the battery 100 (the surface viewed from the direction A in FIG. 2a) is regulated by the JIS standard to have seven combinations of the length and height of the short side of the battery 100, and the length of the long side of the battery 100 (the length of the side parallel to the direction A in FIG. 2a) differs depending on the battery. The battery 100 usually has electrode terminals (hereinafter referred to as "terminals") 110-1 and 110-2 arranged at two positions on a straight line parallel to the long side, toward one side of the long side of the battery 100. Terminals 110-1 and 110-2 of the battery 100 protrude from the battery 100. The battery 100 is fixed to the vehicle 1 by a fixing bracket 120.

[0013] The charger 200 is fixed to the battery 100 using a fixing member described later. The charger 200 charges the battery 100 by supplying a weak current to the battery 100. An example of a method for charging the battery 100 with a weak current is trickle charging. The charger 200 may supply a weak current to the battery 100 intermittently rather than continuously. Any charger that outputs a current (power) may be used as the charger 200. Examples of the charger 200 include a primary battery (e.g., a manganese dry battery or an alkaline dry battery), a secondary battery (e.g., a lithium ion battery), a fuel cell, a power generation device using a potential difference or a temperature difference, and the like. The type of battery is not limited to these.

[0014] As shown in FIG. 2a, in the charging system 10 of this embodiment, a charger 200 is fixed to the battery 100 using a fixing member 210.

[0015] The fixing member 210 is a member that is adapted to various sizes of the multiple batteries 100 that exist, and is installed and fixed to the battery 100 so that the position of the charger 200 relative to the battery 100 is optimal. The fixing member 210 includes positioning portions 212-1, 212-2 each having a hole 211, foot portions 213-1, 213-2 that provide a predetermined space between the charger 200 and the battery 100, an attachment portion 214 that fixes the charger 200 to the fixing member 210, and an expandable portion 215 that has a slidable configuration. In addition, the fixing member 210 may include a fixing bracket 120 for fixing the battery 100 to the vehicle 1.

[0016] The positioning parts 212-1 and 212-2 are shaped like a rectangular thin plate (to the extent that it does not interfere with the attachment of the cable (second cable 310) of the electric system of the vehicle 1 to the terminals 110-1 and 110-2 of the connector 300) that does not distort laterally (it is acceptable if the distortion is suppressed as much as possible). Each of the positioning parts 212-1 and 212-2 is provided with a hole 211 having an outer diameter larger than the outer diameter of the terminals 110-1 and 110-2 near the tip. The positioning parts 212-1 and 212-2 are replaceably attached to the feet 213-1 and 213-2, respectively. Methods for attaching the positioning parts 212-1 and 212-2 to the feet 213-1 and 213-2 include, but are not limited to, methods using metal fittings such as screws, hooks, and clips, magnets, bands, and hook-and-loop fasteners. A plurality of positioning units 212-1, 212-2 may be prepared according to the size of the short side surface (length of the short side in top view) of the battery 100. Also, a position for attaching the foot units 213-1, 213-2 corresponding to the size of the short side surface (length of the short side in top view) may be marked on one positioning unit 212-1, 212-2, and the foot units 213-1, 213-2 may be attached to the positioning unit 212-1, 212-2 according to the position. Note that the fixing member 210 (the foot units 213-1, 213-2) and the positioning units 212-1, 212-2 may be fixed, and the positioning units 212-1, 212-2 may be configured to expand and contract to a length corresponding to the size of the short side surface (length of the short side in top view).

[0017] The foot 213-1 is provided between the positioning portion 212-1 and the attachment portion 214. The foot 213-2 is provided between the positioning portion 212-2 and the expandable portion 215. The foot 213-1 and 213-2 provide a space of a predetermined distance (height h shown in FIG. 2b) between the upper surface of the battery 100 and the charger 200 (including the fixing member 210) (for example, a space of a height such that the fixing member 210 does not come into contact with a protrusion or the like provided on the upper surface of the battery 100, a space that does not block a path for releasing hydrogen gas or the like generated from the battery 100, etc.). Note that the number of the foot 213 is described as two as an example, but the number is not limited to this. When the number of the foot 213 is odd, it is preferable to install one of the foot 213 on the fixing bracket 120.

[0018] The attachment portion 214 is fixed to the charger 200 using, for example, metal fittings such as screws, hooks, and clips provided on the charger 200 side or on the attachment portion 214 of the fixing member 210, a band, a hook-and-loop fastener, an adhesive, a double-sided tape, or the like. The method of fixing the charger 200 and the fixing member 210 is not limited to these.

[0019] The expandable portion 215 is slidably attached to the mounting portion 214 using, for example, a rail or the like. The expandable portion 215 slides in the direction of the arrow shown in Fig. 2a according to the width (horizontal direction of the page) of the battery 100. Note that when the length of expansion and contraction is determined, the expandable portion 215 may be fixed by fitting a wedge-shaped part attached to a screw or a spring tip into a recess so as to prevent the expandable portion 215 from sliding relative to the mounting portion 214.

[0020] An example of a method for mounting the charger 200 to the battery 100 by the fixing member 210 of the charging system 12 in this embodiment will be described below.

[0021] Positioning parts 212-1, 212-2 prepared according to the length of the short side of the battery 100 (size of the short side) are attached to the legs 213-1, 213-2 of the fixing member 210. For example, if the JIS standard specifies "D" (width 173 mm, box height 204 mm), the positioning parts 212-1, 212-2 are attached to match the width of 173 mm. In this case, "D" is written on the positioning parts 212-1, 212-2 to facilitate the user's selection. In addition, when the positioning parts 212-1, 212-2 are expandable, the positioning parts 212-1, 212-2 are expanded or contracted to the position written on the positioning parts 212-1, 212-2 as "D" is written on the positioning parts 212-1, 212-2.

[0022] Next, the holes 211 provided in the positioning portions 212-1 and 212-2 are adjusted to match the positions of the terminals 110-1 and 110-2 of the battery 100. The expandable portion 215 of the fixing member 210 is attached to the mounting portion 214 so as to be expandable and contractible, and the mounting portion 214 and the expandable portion 215 are connected to the positioning portions 212-1 and 212-2 via the legs 213-1 and 213-2, respectively. Therefore, by moving the positioning portions 212-1 and 212-2 in accordance with the terminals 110-1 and 110-2, the expandable portion 215 extends or contracts from the mounting portion 214 in conjunction with them.

[0023] Then, terminals 110-1 and 110-2 of battery 100 are passed through holes in positioning portions 212-1 and 212-2. The length of expandable portion 215 is fixed using screws provided in expandable portion 215. This determines the length of expandable portion 215, the length of which has been adjusted in conjunction with positioning portions 212-1 and 212-2, and charger 200 attached to fixing member 210 can be installed at a position suitable for the lengths of the short and long sides of battery 100 in a top view. Furthermore, a space is provided between battery 100 and charger 200 due to the height of legs 213-1 and 213-2 of fixing member 210.

[0024] Here, the holes 211 provided in the positioning portions 212-1 and 212-2 may be electrically connected to the terminals 110-1 and 110-2 or may be insulated from them. When the holes 211 are electrically connected, the holes 211 are made of a conductive material such as metal, and are in contact with the terminals 110-1 and 110-2, and can be electrically connected to the positive and negative electrodes of the charger 200 via a cable (first cable) connected to the holes 211 provided in the positioning portions 212-1 and 212-2. This enables charging (power supply) from the charger 200 to the battery 100. On the other hand, when the holes 211 are electrically insulated, for example, the fixing member 210 itself may be made of an insulating material, or the inner circumferential surface of the holes 211 may be covered with an insulating material. In this case, it is preferable that the hole 211 has an inner diameter that prevents the fixing member 210 from moving significantly relative to the terminals 110-1 and 110-2 when the terminals 110-1 and 110-2 are passed through the hole 211. When the hole 211 is electrically insulated, the charger 200 and the battery 100 are electrically connected to each other by passing the terminals 110-1 and 110-2 through the hole 211, fixing the fixing member 210 (described later) to the battery 100, and then connecting a first cable electrically connected to the positive and negative electrodes of the charger 200 to the terminals 110-1 and 110-2 via a connector. This first cable is a cable different from the second cable 310 for supplying current from the battery 100 to the electric system of the vehicle 1. The supply of current to the electric system of the vehicle 1 is performed from the battery 100 via the second cable 310 through the connector 300 attached to the terminals 110-1 and 110-2 of the battery 100. A connector (first connector, second connector) may be used for each of the first cable and the second cable 310, or multiple cables may be connected to one connector. Details of the connector will be described later.

[0025] The first cable connecting the charger 200 and the terminals 110-1, 110-2 may be disposed inside the fixing member 210 such as the positioning portions 212-1, 212-2, or may be disposed along the outer surface of the fixing member 210 such as the positioning portions 212-1, 212-2.

[0026] As a method for fixing the positioned fixing member 210 to the battery 100, for example, a method of fixing the fixing member 210 and a fixing bracket 120 that fixes the battery 100 to the vehicle 1 is used. A specific example of fixing the fixing member 210 and the fixing bracket 120 is described below. The fixing bracket 120 is provided with a bolt-shaped rod. The fixing bracket 121 has a hole through which the rod of the fixing bracket 120 passes. The rod of the fixing bracket 120 passes through the hole from above the vertical direction of the charger 200 and the fixing member 210. Then, a nut (a winged nut in the example shown in the figure) is fitted onto the bolt of the rod from above the fixing bracket 121 and tightened. Then, the charger 200 and the fixing member 210 are sandwiched between the fixing bracket 120 and the fixing bracket 121 by the nut and fixed. Therefore, the charger 200 and the fixing member 210 are indirectly fixed to the battery 100 (the configuration shown in FIG. 2b).

[0027] Furthermore, in the case where charger 200 has a structure that allows it to be fixed to fixing member 210 later, charger 200 may be fixed to fixing member 210 after fixing member 210 has been clamped and fixed between fixing bracket 120 and fixing bracket 121 with a nut (the configuration shown in FIG. 2c).

[0028] The bolt-shaped rod provided on the fixing bracket 120 may be an integral part fixed to the fixing bracket 120, or may be removable from the fixing bracket 120. For example, the fixing bracket 120 may be a commonly available part for fixing the battery 100 to the vehicle 1, and the charger 200 and the fixing member 210 may be fixed to the fixing bracket 120 using a bolt that can be attached to the fixing bracket 120 and the fixing bracket 121. The method of fixing the fixing member 210 and the fixing bracket 120 may be, other than the above, a method of fixing them to each other using a band, a hook-and-loop fastener, a hook, a clip, or the like, and is not limited to these.

[0029] After the fixing member 210 is fixed to the battery 100, a connector 300, which is a second connector attached to the end of a second cable 310 for supplying current (power) from the battery 100 to the electrical system of the vehicle 1, is attached to the terminals 110-1, 110-2.

[0030] There are cases where the connector 300 provided on the second cable 310 from the electric system side of the vehicle 1 cannot be replaced. For such a case, it is preferable to structure the charger side connector so that it can be connected to the terminals 110-1 and 110-2 of the battery 100 without replacing the connector 300 on the electric system side. FIG. 3a is a diagram showing an example of the structure of a connector for connecting the first cable from the charger 200 to the terminals 110-1 and 110-2 of the battery 100. The charger side connector, which is the first connector shown in FIG. 3a, is made of a thin, bendable, electrically conductive material such as metal, has a rectangular, trapezoidal, or sector-like shape, and has a connection part 410 that is wound around the sides of the terminals 110-1 and 110-2 to make contact and electrically connect them. The reason why the connection part 410 is shaped like a trapezoid or sector is that it can be used with terminals 110-1 and 110-2 that have a shape that becomes shorter in diameter as they approach the top. The charger side connector also has a fixing part 420 that electrically connects a cable (first cable 430) from the charger 200 side to the connection part 410 and fixes the first cable 430 to the connection part 410. The fixing part 420 is configured, for example, such that the wire from which the sheath of the first cable 430 has been removed is clamped between two metal fittings and screwed in place.

[0031] FIG. 3b is a diagram showing an example of how the connection part 410 shown in FIG. 3a is attached to the terminal 110-1. As shown in FIG. 3b, the connection part 410 is wound around the side of the terminal 110-1 of the battery 100 to make contact. The connection part 410 is attached to the terminal 110-1 by tightening, pinching, or screwing with the connector 300 provided on the second cable 310 from the electric system side of the vehicle 1 from above the connection part 410 wound around the terminal 110-1. This electrically connects the electric system between the battery 100 and the vehicle 1, and the battery 100 and the charger 200. It is desirable that the fixing part 420 is connected as small as possible to the lower part of the connection part 410 when the connection part 410 is wound, in order to provide a sufficiently large portion where the connector on the electric system side of the vehicle 1 (the connector 300 shown in FIG. 2) is attached to the connection part 410. In addition, in the case where the hole 211 provided in the positioning portions 212-1 and 212-2 of the charger side connector is electrically connected to the terminals 110-1 and 110-2, the hole 211 may replace the fixing portion 420, and the connection portion 410 may be provided in the hole 211.

[0032] 4 is a diagram showing another example of the structure of a connector for connecting the first cable from the charger 200 to the terminals 110-1 and 110-2 of the battery 100. If the connector 300 provided in advance on the second cable 310 from the electric system side of the vehicle 1 can be replaced with another connector, the provided connector 300 may be removed from the second cable 310 on the electric system side, and a connector may be used in which the wires from which the sheaths of the first cable 430 on the charger 200 side and the second cable 310 on the electric system side of the vehicle 1 are removed are fastened with metal fittings corresponding to the respective wires provided in one connector (a connector other than the provided connector in advance). As shown in FIG. 4, the second cable 310 and the first cable 430 can be attached to the terminals 110-1 and 110-2 of the battery 100 via a connecting portion 510 provided in one connector, and electrically connected. (Second embodiment)

[0033] Fig. 5 is a diagram showing another example of the manner in which the charger 200 is fixed to the battery 100 shown in Fig. 1. As shown in Fig. 5, in the charging system 12 in this embodiment, the charger 200 is fixed to the battery 100 using a fixing member 220. The battery 100 and the charger 200 are the same as those in the first embodiment. The following description will focus on the points that are different from the first embodiment, and the description of the points that are the same as the first embodiment may be omitted.

[0034] The fixing member 220 is a member that is adapted to various sizes of the multiple batteries 100 that exist, and that is installed on and fixes the charger 200 to the battery 100 so that the position of the charger 200 relative to the battery 100 is optimal. Fixing member 210 includes positioning portions 212-1, 212-2 each having hole 211, foot portions 213-1, 213-2 that provide a predetermined space between charger 200 and battery 100, attachment portion 224 that fixes charger 200 to fixing member 210, and expandable portion 225 having a slidable configuration. That is, fixing member 220 includes attachment portion 224 instead of attachment portion 214 included in fixing member 210 in the first embodiment, and includes expandable portion 225 instead of expandable portion 215.

[0035] The positioning units 212-1 and 212-2 are similar to those in the first embodiment, and therefore the description thereof will be omitted.

[0036] The foot 213-1 is provided between the positioning portion 212-1 and the attachment portion 224. The foot 213-2 is provided between the positioning portion 212-2 and the expandable portion 225. The foot portions 213-1 and 213-2 provide a space of a predetermined distance (height h shown in FIG. 5) between the upper surface of the battery 100 and the charger 200 (including the fixing member 220) (for example, a space of a height such that the fixing member 220 does not come into contact with a protrusion or the like provided on the upper surface of the battery 100, a space that does not block a path for releasing hydrogen gas or the like generated from the battery 100, etc.). The number of the foot portions 213 is not limited, as in the first embodiment.

[0037] The mounting portion 224 is fixed to the charger 200 using, for example, a screw, a hook, a metal fitting such as a clip, a band, a hook-and-loop fastener, an adhesive, a double-sided tape, or the like provided on the charger 200 side or the mounting portion 224 of the fixing member 220. The method of fixing the charger 200 and the fixing member 220 is not limited to these. The mounting portion 224 has a member that abuts against the side of the battery 100 and applies force in the lateral direction of the paper (at least one direction between the direction B shown in FIG. 5 and the direction opposite to the direction B from the opposite side). For example, a screw hole through which a bolt passes penetrates the mounting portion 224, and by fitting a screw (a winged bolt in the example shown in FIG. 5) into the screw hole and tightening it, the screw abuts against the side of the battery 100 and applies force. It is preferable to provide a cushioning material or a non-slip material (for example, silicon, rubber, cork, spring, etc.) at the tip of the screw to prevent the side of the battery 100 from being scratched. Instead of using a combination of a screw hole and a screw, silicone, rubber, cork, a spring, or the like may be provided on the side surface of the mounting portion 224 of the battery 100 and brought into contact with the side surface of the battery 100 to apply force.

[0038] The expandable portion 225 is slidably attached to the mounting portion 224 using, for example, a rail or the like. The expandable portion 225 slides in the direction of the arrow shown in FIG. 5 according to the width (horizontal direction of the paper) of the battery 100. In addition, when the length of expansion and contraction is determined, the expandable portion 225 may be fixed by fitting a wedge-shaped member attached to a screw or a spring tip into a recess so as not to slide relative to the mounting portion 224. In addition, the expandable portion 225 abuts against a side surface of the battery 100 (the side surface opposite to the side surface on which the mounting portion 224 abuts) and has a member that applies force in the horizontal direction of the paper surface (at least one direction between the C direction shown in FIG. 5 and the direction facing the C direction from the opposing side surface) (the opposite direction to the direction in which the mounting portion 224 applies force). The member that applies the force is the same as that of the mounting portion 224. In addition, the member that applies the force may be provided on at least one of the mounting portion 224 and the expandable portion 225.

[0039] An example of a method for mounting the charger 200 to the battery 100 by the fixing member 220 of the charging system 12 in this embodiment will be described below.

[0040] As shown in FIG. 5, in this embodiment, fixing members 220 are fixed to the battery 100 so as to sandwich the battery 100 from two opposing side surfaces of the battery 100.

[0041] Positioning parts 212-1, 212-2 prepared corresponding to the length of the short side (size of the short side) of the battery 100 are attached to the legs 213-1, 213-2 of the fixing member 220. Furthermore, if the positioning parts 212-1, 212-2 are expandable members, the positioning parts 212-1, 212-2 are expanded or contracted to positions written on the positioning parts 212-1, 212-2 corresponding to the length of the short side (size of the short side) of the battery 100.

[0042] Next, the holes 211 provided in the positioning parts 212-1 and 212-2 are adjusted to match the positions of the terminals 110-1 and 110-2 of the battery 100. The expandable part 225 of the fixing member 220 is configured to be slidable in the direction of the arrow shown in FIG. 5 according to the width of the battery (horizontal direction of the paper). The mounting part 224 is connected to the positioning part 212-1 via the foot part 213-1. The expandable part 225 is connected to the positioning part 212-2 via the foot part 213-2. Therefore, by moving the positioning parts 212-1 and 212-2 in accordance with the terminals 110-1 and 110-2, respectively, the expandable part 225 extends or contracts from the mounting part 224 in conjunction with the movement. Then, the terminals 110-1 and 110-2 of the battery 100 are passed through the holes 211 provided in the positioning parts 212-1 and 212-2. Here, the length of the expandable portion 225 is fixed by a screw provided in the expandable portion 225 .

[0043] Furthermore, the battery 100 is sandwiched using a member (e.g., tightening member 230) that is provided on at least one of the attachment portion 224 and the expandable portion 225 of the fixing member 220 and applies a force in the lateral direction of the page (at least one of the direction B shown in FIG. 5 and the direction opposite to the direction C from the opposing side surface). As a result, the length of the expandable portion 225, the length of which is adjusted in conjunction with the positioning portions 212-1 and 212-2, is determined, and the charger 200 attached to the fixing member 220 can be installed at a position suitable for the lengths of the short sides and long sides of the battery 100 in a top view. Furthermore, a space is provided between the battery 100 and the charger 200 due to the height of the legs 213-1 and 213-2 of the fixing member 220. Furthermore, in this embodiment, unlike the first embodiment, charger 200 attached to fixing member 220 is not fixed to battery 100 using fixing bracket 120 and fixing bracket 121, but rather, battery 100 is sandwiched between attachment portion 224 and expansion / contraction portion 225 of fixing member 220, thereby fixing charger 200 attached to fixing member 220 to battery 100. This allows a general fixing bracket 120 to be used for fixing battery 100 to vehicle 1.

[0044] The connector 300 provided on the second cable 310 on the vehicle's electrical system side, and the first cable and connector (charger side connector) for supplying current (power) from the charger 200 side to the terminals 110-1, 110-2 are the same as those described in the first embodiment, including the case where the hole 211 is electrically connected to the terminals 110-1, 110-2 and the case where it is insulated.

[0045] In this way, in the present invention, the charger 200 is connected to the vehicle-mounted battery 100, and the charger 200 supplies a weak current to the battery 100. This makes it possible to avoid a situation where the battery 100 cannot supply sufficient current to the vehicle's electrical system due to natural discharge, i.e., a dead battery. In addition, the fixing member 210 or the fixing member 220 to which the charger 200 is fixed is installed at an appropriate position on the battery 100 using the terminals 110-1 and 110-2 of the battery 100. The terminals 110-1 and 110-2 of the battery 100 are shaped to protrude from the battery 100. The terminals 110-1 and 110-2 are passed through holes 211 provided in the fixing member 210 or the fixing member 220. The fixing member 210 or the fixing member 220 expands and contracts in conjunction with the size of the battery 100. This provides a space in which the charger 200 and the fixing member 210 or the fixing member 220 do not hit the terminals 110-1 and 110-2 of the battery 100, do not cover the upper part of the terminals 110-1 and 110-2, and do not block the path for escaping hydrogen gas and the like generated from the battery 100. Therefore, the charger 200 can be easily installed in an appropriate position on the battery 100 even for batteries of various sizes. In addition, generally, electric and electronic components of an automobile require measures against vibration based on standards such as ISO-16750-3. By fixing the charger 200 to an appropriate position with respect to the battery 100 using the fixing member 210 or the fixing member 220, the charger 200 and the battery 100 can be easily maintained in a fixed state by always being electrically connected to each other using a cable or the like even while the vehicle 1 is running in the engine room. There is no need to attach and detach the charger every time charging is performed, and as a result, the battery 100 can be easily charged.

[0046] Furthermore, the fixing member 210 to which the charger 200 is fixed is fixed to a fixing bracket 120 that fixes the battery 100 to the vehicle 1. Alternatively, the fixing member 220 to which the charger 200 is fixed is fixed to the battery 100 so as to sandwich the battery 100. This allows the charger 200 to be securely fixed to the vehicle 1. Generally, components mounted in the engine room of a vehicle need to be securely fixed to the vehicle. As described above, in this embodiment, the charger 200 can be fixed to the battery 100 that is already fixed, and this requirement can be met when mounting the charger 200.

[0047] In the above-described example, the fixing member 210 or the fixing member 220 fixed to the battery 100 is attached to the bottom surface of the charger 200 and fixed thereto, but the fixing member may be attached to the top surface of the charger 200 and fixed so as to sandwich the charger 200 between the fixing member and the battery 100. Also, the fixing member 210 or the fixing member 220 may be attached to the side surface of the charger 200 and fixed thereto. Also, the shape of the fixing member may be a shape that allows the charger 200 to be attached to the battery 100 according to the shape of the charger 200. For example, the fixing member may be attached to the charger 200 so as to follow three or more side surfaces of the charger 200, and the charger 200 may be fixed to the battery 100.

[0048] The present invention may be realized by combining each of the embodiments. [Explanation of symbols]
