[0026] This disclosure provides many different embodiments, or examples, for implementing various features of the subject matter provided. For the sake of brevity, specific examples of components and arrangements are described below. These are, of course, merely examples and are not intended to be limiting. For example, in the descriptions below, a method of forming a first feature on or above a second feature may include embodiments in which the first and second features are formed in direct contact. It may also include embodiments in which an additional feature is formed between the first and second features, and the first and second features are not in direct contact. Furthermore, reference numbers and / or letters may be repeated in various examples in this disclosure. This repetition is for the sake of brevity and clarity and does not in itself define the relationships between the various embodiments and / or configurations discussed.

[0027] The foregoing outlines some features of embodiments so that those skilled in the art may better understand aspects of the present disclosure. Those skilled in the art will readily understand, based on the present disclosure, that other processes or structures may be designed or modified to perform the same purposes and / or achieve the same advantages as the embodiments described herein. Those skilled in the art will also understand that such equivalent configurations will not deviate from the spirit and scope of the present disclosure, and that various changes, substitutions, and modifications may be made without departing from the spirit and scope of the present disclosure.

[0028] A general objective of the present invention is to provide a robust and reliable battery handle without increasing the size or cost of the battery. The embodiments described herein relate to a handle that is detachably attached to a battery. This handle can provide a robust means for transporting and handling the battery without requiring extra packaging space for a molded handle or a recess to accommodate such a handle. Furthermore, the handle can be mounted in various positions, providing a convenient and easy-to-use handle in a variety of situations. In embodiments of the present disclosure, the handle is attached to the battery via the battery terminals. This further saves space on the device, limits the number of parts required for battery operation, and reduces the risk of losing parts used to attach the handle to the battery.

[0029] Figure 1 is a perspective view of a battery assembly 100 including a battery handle 110 according to one embodiment. The battery assembly may include a battery having a battery body 105 and a top surface 115. The top surface 115 may extend in a first direction and a second direction, as indicated by the axes in Figure 1.

[0030] The top surface of the battery may consist of multiple sets of terminal positions. For example, in the embodiment shown in Figure 1, the top surface 115 includes a first set of terminal positions 120A / 120B and a second set of terminal positions 125A / 125B. The terminal positions of one set may be spaced apart from each other in a first direction. The first set of terminal positions 120A / 120B and the second set of terminal positions 125A / 125B may be spaced apart from each other in a second direction. In this way, the first set of terminal positions 120A and 120B may be located in the central part of the top surface in a second direction, and the second set of terminal positions 125A and 125B may be located in the outer part of the top surface in a second direction.

[0031] Each terminal position 120A / 120B / 125A / 125B corresponds to the polarity of the battery and may include a port or input that accepts battery terminals 130A / 130B, which provide a connection between the battery and an external device. For example, 120A corresponds to a first polarity of the battery, and 120B corresponds to a second polarity. The first polarity is either positive or negative, and the second polarity is the opposite of the first polarity. Similarly, 125A corresponds to either positive or negative polarity, and 125B corresponds to the opposite polarity. In one embodiment, 120A and 125A provide a port or input to the positive polarity of the battery, and 120B and 125B provide a port or input to the negative polarity of the battery. In some embodiments, if the input or port of a terminal position is not in use, a cover 140A / 140B may be placed over the input or port of the terminal position for protection. For example, as shown in Figure 1, the second set of terminal positions 125A and 12B are not used and are protected by covers 140A / 140B.

[0032] The battery assembly 100 further includes a handle 110 that is detachably mounted on the top surface 115. The handle can be mounted on the top surface in different positions. For example, the handle 110 may be provided and mounted so that its end aligns with a first set of terminal positions 120A / 120B. Alternatively, the handle 110 may be mounted so that its end aligns with a second set of terminal positions 125A / 125B. After being mounted in one position, the handle 110 can be removed from that position and remounted in another position.

[0033] For example, as shown in Figure 1, the handle 110 can initially be aligned to a first set of terminal positions 120A / 120B. As will be described later, the handle 110 is connected to the ports or inputs of these terminal positions via battery terminals 130A and 130B. The user may later decide, based on the surrounding circumstances, that it is more convenient to position the handle 110 towards the outer part of the top surface 115. Therefore, the user can disconnect terminals 130A / 130B from the inputs of 120A / 120B in order to remove the handle 110 from the first position. The user can then move the handle 110 to a second position located at 125A / 125B and attach the handle 110 in that position.

[0034] As described above, the handle 110 can be attached to the battery via battery terminals 130A / 130B. These terminals serve as both fasteners and electrical connectors between the battery and external devices such as jumper cables. Each terminal position may have a port or input that allows the battery terminal to be electrically connected to the battery poles. In one embodiment, the input may include a threaded sidewall that mates with the threaded portion of the battery terminals 130A / 130B. As will be discussed later with respect to Figure 5, this configuration allows the user to screw the battery terminal through the handle opening and attach the handle. The user can also unscrew the battery terminal and remove the handle.

[0035] The battery assembly 100 may further include protective caps 135A / 135B that cover the exposed portions of the battery terminals 130A / 130B. These caps provide electrical insulation to the battery terminals and offer resistance to corrosion. The protective caps 135A / 135B are removable and can be removed from the battery terminals 130A / 130B when an electrical connection to or from the battery is required. When the battery terminals 130A / 130B are not in use, the protective caps 135A / 135B can be fitted over the exposed portions of the terminals to protect them from electrical short circuits and corrosion.

[0036] In other embodiments, the handle 110 may be attached to the inputs of the first set 120A / 120B or the second set 125A / 125B of terminal positions via a pair of screws or standard bolts. In one embodiment, the handle can be securely and detachably attached to the top surface of the battery using screws. The screws secure the handle to one set of terminal positions, while the battery terminals 130A / 130B are located at the other terminal position, enabling connection between the battery and an external device.

[0037] As will be described later with reference to Figures 9A-9C, in some embodiments the battery assembly 100 may include four battery terminals 130. In these embodiments, the cover 140A / 140B is not installed, and the battery terminals 130 may be connected to inputs at each terminal position on the top surface.

[0038] Figures 2A to 2C show various perspective views of the handle 110 according to one embodiment. Figure 2A is a side view of the handle 110 according to one embodiment. Figure 2B is a top view of the handle 110 according to one embodiment. Figure 2C is a bottom view of the handle 110 according to one embodiment.

[0039] The handle 110 may have a first end 201, a second end 202, and a grip portion 203 extending between the first end 201 and the second end 202. The grip portion 203 allows the user's hand to engage with the handle. The grip portion 203 may include a lattice structure 215. In one embodiment, the handle 110 is a rigid body formed from a plastic material, but the material is not limited thereto. For example, the handle 110 may be any kind of molded product, or any electrical insulating material that provides sufficient structure to support a battery. The lattice structure 215 may include areas where the material of the handle 110 is absent. This can reduce the weight of the handle, save on material costs, and provide a more comfortable interface for the user to grip. In one embodiment, the lattice portion 215 may be honeycomb or hexagonal in shape.

[0040] The first end 201 and the second end 202 may each include a bottom 204 having holes 205A / 205B. The holes 205A / 205B provide space for the battery terminals to pass through so that the handle is securely fixed to the battery when the battery terminals are screwed into the inputs at the terminal positions on the top surface of the battery. In one embodiment, the first end 201 may have a first hole 205A and the second end 202 may have a second hole 205B. In one example of attaching the handle 110 to the battery, the first hole 205A may be aligned with terminal position 120A and the second hole 205B may be aligned with terminal position 120B. The battery terminal 130A is screwed into the input at terminal position 120A through hole 205A. The battery terminal 130B is screwed into the input at terminal position 120B through hole 205B. This ensures that the handle 110 is securely attached to the top surface 115 of the battery, while also providing external connections to both the positive and negative terminals of the battery via the battery terminals 130A / 130B.

[0041] The first end 201 and the second end 202 may each further include a pair of vertical side walls 207. Each end includes two vertical side walls 207 spaced apart in the width direction of the handle. The vertical side walls 207 of each end are spaced far enough apart from each other to ensure sufficient space for the battery terminals to pass through the holes 205A / 205B and to maintain a gap between the battery terminals and the inner surfaces of the vertical side walls 207. This gap between adjacent vertical side walls 207 can be made to coincide with the location of the holes 205A / 205B in the bottom 204 so that the battery terminals are located in the gap and pass through the overlapping holes.

[0042] In one embodiment, the handle 110 may further include an inclined side wall 206 extending from the bottom 204 toward the grip portion 203. In Figure 2A, the vertical side wall 207 obstructs the view of the inclined side wall 206. However, Figures 2B and 2C show the position of the inclined side wall 206. As seen in Figure 2B, the bottom 204 may be surrounded by side walls on three sides. In the width direction of the handle 110, the bottom 204 may be bounded by the vertical side wall 207. However, in the direction in which the handle 110 extends, the bottom 204 may be open on the outside and bounded on the inside by the inclined side wall 206. The inclined side wall 206 may constitute a lattice structure 215. The inclined side wall 206, together with a portion of the vertical side wall 207, may connect the bottom 204 to the grip portion 203 of the handle.

[0043] Figures 3A to 3C show various perspective views of the handle 310 according to one embodiment. Figure 3A is a side view of the handle 310 according to one embodiment. Figure 3B is a top view of the handle 310 according to one embodiment. Figure 3C is another side view of the handle 310 according to one embodiment.

[0044] The embodiments shown in Figures 3A to 3C differ from those shown in Figures 2A to 2C only in terms of the shape and design of the grid structure. Otherwise, the structure and components of the handle 310 in Figures 3A to 3C may be the same as those shown in the preceding drawings. Therefore, the reference numbers of identical structures are not repeated. As shown in Figures 3A to 3C, the handle 310 may include a grid structure 315, which has a grid shape.

[0045] Figures 4A to 4C show various perspective views of the handle 410 according to one embodiment. Figure 4A is a side view of the handle 410 according to one embodiment. Figure 4B is a top view of the handle 410 according to one embodiment. Figure 4C is another side view of the handle 410 according to one embodiment.

[0046] The embodiments shown in Figures 4A-4C differ from those shown in Figures 2A-2C and 3A-3C only in terms of the shape and design of the grid structure. Otherwise, the structure and components of the handle 410 may be the same in Figures 4A-4C as those shown in the prior drawings. Therefore, reference numbers for identical structures are not repeated. As shown in Figures 4A-4C, the handle 410 may include a grid structure 415, which includes circular cut-outs.

[0047] Figure 5 shows a side view of a battery assembly 100 according to one embodiment. Figure 5 shows one terminal position 120 of a first set of terminal positions and one terminal position 125 of a second set of terminal positions. In one embodiment, a handle 110 is configured to be attached to the first set of terminal positions, including terminal position 120. The handle 110 can be attached to the battery via a battery terminal 130. The battery terminal 130 can be aligned with the input portion of terminal position 120 so that the threaded portion of the battery terminal 130 is screwed into the threaded portion of the input portion of terminal position 120. The handle 110 can be aligned so that a hole at the bottom is aligned axially with the battery terminal 130 and the input portion of terminal position 120.

[0048] During installation, the handle is sized and shaped so that the battery terminal 130 and terminal cap 135 fit into the space between adjacent vertical side walls 107. For example, the battery terminal 130 may include a first threaded portion and a second threaded portion separated by a nut portion 510 in the center. The nut portion 510 may be wider than the threaded portion. The nut portion 510 contributes to holding the terminal cap 135 in place, but other shapes of the battery terminal may be used in some embodiments. Non-limiting examples include a continuous threaded structure without a nut portion in the center, or a structure in which only one end is threaded.

[0049] When the handle 110 is attached, the first threaded portion 100 is positioned through the handle and can be screwed into the input portion of the terminal position 120. In this position, the battery terminal 130 and the vertical side wall 207 can divide the gap between adjacent vertical side walls into a pair of gaps defined between the vertical side wall 207 and the nut portion 510 of the battery terminal 130. The first gap 505A exists between the nut portion 510 of the battery terminal 130 and the first vertical side wall 207, and the second gap 505B exists between the nut portion 510 of the battery terminal 130 and the second vertical side wall 207.

[0050] This configuration may provide additional protection against accidental short circuits to the battery terminals during storage and handling. The gaps 505A / 505B may provide sufficient space for connecting external clamps or cables to the battery terminals 130 when necessary, while the vertical sidewalls 207 act as barriers to prevent undesirable contact with the terminals and / or clamps. Furthermore, the sidewalls are spaced sufficiently apart to accommodate protective caps 135, so that the terminals can be covered with caps when not in use. Thus, embodiments of the present disclosure may provide a double layer of protection against accidental short circuits of the terminals.

[0051] Referring to Figures 6-8, one example of a mechanism for connecting the battery terminals to the battery will be described below. Figure 6 is a top perspective view of the handle 610 according to one embodiment. Figure 7 is a bottom perspective view of the handle 710 according to one embodiment. Figure 8 is a perspective view showing the mounting state between the handle 710 and the top surface of the battery 115 according to one embodiment.

[0052] As shown in Figure 6, in one embodiment, the handle 610 may have an upper surface 615 and a lower surface 620. A recess 625 may be provided on the upper surface. The recess 625 may have a size and shape for holding a tool. In one embodiment, the size and shape of the recess are those of a hex wrench. The handle 610 may further include a hex wrench 630 housed in the recess 625. The hex wrench 630 may have an end that conforms to the shape of a battery terminal and may be configured to assist in attaching or detaching the handle to the battery.

[0053] Figure 7 shows a handle 710 according to another embodiment. The handle 710 may have an upper surface (not shown) and a lower surface 720. A recess 725 may be provided on the lower surface. The recess 725 may have a size and shape for holding a tool. In one embodiment, the size and shape of the recess are those of a hex wrench. The handle 710 may further include a hex wrench 730 housed in the recess 725. The hex wrench 730 may have an end that conforms to the shape of a battery terminal and may be configured to assist in attaching or detaching the handle to the battery.

[0054] Figure 8 shows the battery assembly 800 and how the handle 710 is attached to the top surface 115 of the battery using a hex wrench 730. As shown in Figure 8, the handle 710 can be aligned to the first set of terminal positions 120A / 120B, for example, as described above with respect to Figure 1. By providing the battery terminals 130, the handle can be securely and detachably attached to the battery. The battery terminals 130 can be screwed into the input of terminal position 120B using the hex wrench 730 (which was previously stored in a recess on the bottom surface of the handle 710). Although Figure 8 shows attachment using a hex wrench 730, the disclosure is not limited thereto. For example, it can be screwed in using a standard wrench or any other means that can securely fix the battery terminal to the input of the terminal position. Furthermore, as described above, in another embodiment the handle can be attached with screws. In such a configuration, the handle can be securely and detachably attached to the battery by screwing the input of the terminal position with a standard screwdriver.

[0055] Figure 8 and other figures show the handle being mounted to a first set of terminal positions 120A / 120B, but this disclosure also covers a handle that can be mounted to multiple positions, including positions corresponding to a second set of terminal positions 125A / 125B. This versatility allows for convenient placement of the handle depending on the battery installation configuration.

[0056] Figures 9A to 9C show perspective views of a battery assembly 100 according to one embodiment. In one embodiment, the input sections at terminal positions 120A / 120B and 125A / 125B are not covered and are configured to receive battery terminals from among a plurality of battery terminals. In addition to the aforementioned battery terminals 130A / 130B, the battery assembly 100 may include four battery terminals: battery terminals 130C and 130D.

[0057] Figure 9A shows a first configuration in which the handle is completely detached from the battery. Under certain circumstances, a user may decide that detaching the battery makes it easier to access the battery terminals. For example, in one embodiment, the battery may be a lithium-ion battery used as a power source for a vehicle or vessel. After transporting and positioning the battery in place within the vehicle or vessel using the handle, a user may decide that it is advantageous to completely detach the handle from the top of the battery in order to expose a wider portion of the top surface of the battery. This also makes it possible to create space for mounting a battery cover or a battery bracket to hold the battery in place.

[0058] As shown in Figure 9A, after removing the handle, the user can then screw the battery terminals 130A / 130B back into the inputs of the first terminal positions 120A / 120B to enable external connection to the battery. In one embodiment, the battery terminals 130A / 130B may be connected to an external cable 905A / 905B. This allows the battery to supply or receive power to an external device (for example, to enable battery charging). Alternatively (not shown in Figure 9A), the battery terminals 130A / 130B can be installed in the second terminal positions 125A / 125B. Furthermore (not shown in Figure 9A), it is also possible to install battery terminals 130C / 130D in terminal positions 125A / 125B and battery terminals 130A / 130B in terminal positions 120A / 120B. This ensures positional flexibility when connecting to an external device.

[0059] Figure 9B shows another configuration in which the handle 110 is mounted on a second set of terminal positions 125A / 125B located on the outer part of the top surface of the battery. In some cases, mounting on the outer part of the top surface of the battery may be the most accessible way for the user to handle the battery. For example, in battery installations in vehicles or boats, the central part of the battery may be out of reach. In such situations, if the user wants to remove or handle the battery, mounting the handle on a more easily accessible outer part may be easier.

[0060] As shown in Figure 9B, the handle and battery assembly of the present disclosure achieves such mounting. Specifically, the handle 110 is attached to the inputs of the second set 125A / 125B of terminal positions using battery terminals 130C / 130D, while the battery terminals 130A / 130B are attached to the first set 120A / 120B of terminal positions. Furthermore, the battery terminals 130A / 130B may be connected to external cables 905A / 905B. In this configuration, the external cables 905A / 905B can be easily attached to the battery terminals 130A / 130B while the handle 110 remains attached to the top surface of the battery. At the same time, the handle 110 prevents short circuits of terminals 130C / 130D. Alternatively, the handle 110 may be attached via a pair of screws instead of the battery terminals 130C / 130D. This configuration allows the handlebars to be securely and detachably attached to the battery while providing easy access to battery terminals 130A / 130B for external connections.

[0061] Figure 9C shows another configuration in which the handle 110 is mounted on the first set of terminal positions 120A / 120B. In this configuration, the user may find it more convenient if the handle were mounted in the central part of the top surface, and it may also be more convenient if the connection to the external cable is made to the terminals located towards the outer part of the top surface.

[0062] As shown in Figure 9C, this can be achieved by connecting the handle 110 to the central section via battery terminals 130A / 130B, which are connected to the inputs of a first set of terminal positions 120A / 120B. Terminals 130C / 130D can be connected to the inputs of a second set of terminal positions 125A / 125B. External cables 905A / 905B can be easily connected to terminals 130C / 130D while the handle 110 prevents short circuits of terminals 130A / 130B. Alternatively, the handle 110 can be attached with a pair of screws instead of battery terminals 130A / 130B. In this configuration, the handle can be securely and detachably attached to the battery while providing easy access to battery terminals 130C / 130D for external connections.

[0063] Figure 10 is a flowchart illustrating a method for assembling a battery with a handle according to an embodiment. In one example of the method, the process may begin with step 1010, in which an assembly worker receives the battery. The received battery is identical to the one shown in Figure 1, but the handle and battery terminals may not be attached. The battery may have multiple battery mounting positions on its upper surface. For example, as mentioned above with respect to Figure 1, the battery may have a first set of terminal positions located in the central part of the top surface and a second set of terminal positions located in the outer part of the top surface. The method proceeds in step 1015, in which the installer receives the handle. Similar to the battery, the handle may be as shown in Figure 1, but it is not connected to the battery.

[0064] In 1020, the installer can attach the handle to the battery in a first position. The first position may correspond to a first set of terminal positions or a second set of terminal positions. Attachment may be achieved via multiple battery terminals. For example, the handle may have a first end including a bottom with a first hole and a second end including a bottom with a second hole. The first set of terminal positions and the second set of terminal positions may include screw inputs corresponding to the threaded portions of multiple battery terminals. Attaching the handle to the battery may include aligning the first and second holes of the handle with the inputs of the first or second set of terminal positions and screwing the multiple battery terminals through the holes in the handle into the screw inputs.

[0065] In step 1025, the installer can evaluate whether the handle is in the optimal position. Depending on the situation, it may be more convenient to handle the battery via a handle located in the center of the battery, or it may be more convenient to handle the battery via a handle located towards the outside of the battery. If the installer determines that the first position is the optimal position, the method proceeds to step 1030 and ends there. However, if the installer determines that the first position is not the optimal position for the handle, the method proceeds to step 1040.

[0066] In 1040, the installer can remove the handle from the battery. This can be achieved by disconnecting the battery terminals from the screw-type input and removing the handle from the top of the battery. At this point, the installer can re-evaluate whether the handle is in the optimal position, as shown in Figure 1042. As mentioned above, there may be situations where the installer wants to completely remove the handle and expose the top of the battery. If the installer determines that removing the handle is optimal, the procedure is completed as shown in Figure 1030.

[0067] However, if the installer determines that this is not the best configuration in the situation, the method proceeds to 1045, in which the installer can reattach the handle to a second position corresponding to a set of terminals that were not previously aligned. This reattachment can be achieved by the same mechanism described above with respect to 1020.

[0068] After installing the handle in the second position, the procedure returns to 1025, where the installer re-evaluates whether the handle is in the optimal position. If it is, the procedure ends at 1030. If it is not in the optimal position, the handle is removed again at 1040 and reinstalled in a different position at 1050. The procedure ends when the installer determines that the handle is in the optimal position.

[0069] In some embodiments, the battery and handle may be supplied fully assembled, with the handle already mounted in place. In such a scenario, the method begins with the process shown in 1050. First, in 1052, the installer receives the fully assembled battery, including the handle mounted on top of the battery. Next, in 1054, the installer begins the process of removing the handle and selecting the optimal position for the handle. For example, after removing the handle, in 1056, the installer considers whether removing the handle is the optimal configuration. If so, the method proceeds to 1030, and the process ends. However, if the installer decides that the handle should be mounted, the installer proceeds to 1010, performing the procedure described above.
