[0023] According to various embodiments, the battery strap 123 connects multiple battery cells 107 (e.g., six battery cells) in series. According to various embodiments, the battery strap 123 may be a straight-path cast strap. The battery cells 107 may include several flat grids stacked together. The grids may have tabs extending from the top of the grids. The strap 123 may be understood as connecting the tabs of the grids in the cells 107 together.
[0024] Figure 1 An isometric view of a battery 101 with the battery straps 123 or conductive straps according to various embodiments is shown. The battery straps 123 may include connecting straps 125 and end straps 131. The battery 101 can be seen to include a plurality of flat grids stacked together and arranged in a plurality of cells 107.
[0025] The battery 101 includes a battery housing 103. The battery straps 123 disclosed herein according to various embodiments may be "cast straps." The straps may be "cast," where the straps are cast onto the tabs of the battery element tabs. Five connecting straps 125 are provided. Figure 1 Six battery elements are shown coupled in series. In the example shown, a positive terminal and a negative terminal (a first terminal 133, a second terminal 135) are shown on one side of the battery. The connecting strip 125 is formed integrally in the end strip 131. Figure 1 113, which are shown as parallel planes that pass through the cutouts 113 provided in the battery cell walls 111 to connect adjacent cell elements in series. In various embodiments, the connecting straps 125 can be considered to have a thickness such that the cell walls 111 are taller than the connecting straps 125. In particular, the connecting straps 125 can have a height 127 that is lower than the height 115 of the cutouts 113. Furthermore, the connecting straps 125 can have a width 117 that is smaller than the width 117 of the cutouts.
[0026] In various embodiments, the connecting strips 125 can be seen connecting the tabs of a battery plate of a battery element 109 having a first polarity to the tabs of a battery plate of a second battery element 109 having an opposite polarity. Figure 1As can be seen in FIG, a terminal 135 (e.g., a positive terminal) is provided at the lower right corner of the battery 101, the terminal 135 being connected to a terminal strip 131 having a certain polarity, the terminal strip 131 being connected to the tab of the plate of the battery element 109 having the same polarity (e.g., positive polarity). Similarly, according to various embodiments, Figure 1 Another terminal 133 (eg, a negative terminal) can be seen disposed at the lower left corner of the battery 101, which is connected to an end strap 131 that is connected to the tab of a plate (eg, a negative plate) of the battery element 107.
[0027] Figure 2 A top view of a battery 101 having ribbons 123 (e.g., cast ribbons) is shown according to various embodiments. A first row 119 and a second row 121 of battery ribbons 123 are shown. Figure 2 The first row 119 can be seen at the top, while the second row 121 can be seen at the Figure 2 1 and 2. As seen below the first row 119 in the drawings. In various embodiments, the first row 119 includes three connecting straps 125. The second row 121 - which has a first battery terminal 131 and an end strap 131 and a second battery terminal 135 and an end strap 131 - has two connecting straps 125, which are positioned parallel to the three connecting straps 125 in the first row 119. Although specific configurations are shown and described, variations thereon are also acceptable. For example, the positive terminal and the negative terminal can be on the first row or the second row or on both the first and second rows (e.g., one terminal on each row). The strap can be understood to be cast onto the positive tab or the negative tab provided in each battery element, which is separated from other battery elements by a partitioning cell wall 111.
[0028] from Figure 2 As can be seen, a cutout 113 or groove can be provided for the connecting strip 125, which can be found in a single location along each battery cell wall 111. In various embodiments, it can be seen that the cutout 113 is appropriately positioned relative to the tabs of the battery element 109 and the location of the connecting strip 125 attached to the tabs. The positioning of the connecting strip 125 and the cutout 113 is Figure 2 13 or grooves in the cell wall. This can advantageously allow for further open space (i.e., a common headspace 137) within the cell 101 cavity.
[0029] Figure 3 A battery strap 123 is shown on the exterior of the battery or battery housing according to various embodiments. It can be seen that the five connecting straps 125 have substantially the same shape. Similarly, the end straps with the terminals can be substantially the same shape. In various embodiments, the connecting straps 125 can be substantially rectangular when viewed from above. In various embodiments, the connecting straps 125 can be substantially rectangular prism-shaped. The battery straps 123 can widen from the top surface to the bottom surface. In various embodiments, the connecting straps 125 can have two protrusions 130 on the side of the casting strap.
[0030] It should be understood that the battery 101 may further include a battery cover 105 disposed on the housing 103 . Figure 4 A battery cover 105 is shown positioned relative to the battery strip 123 according to various embodiments. In various embodiments, the cover 105 can be sized to receive the strip 123 and the terminals 133, 135. The cover 105 can also include a battery element separator sized to accommodate the strip 123 disclosed herein. Additionally, in various embodiments, the cover 105 can be sized to receive the terminals 133, 135 disposed on opposite ends of the battery strip on one side. In various exemplary embodiments, a first terminal post (positive) and a second terminal post (negative) can be positioned in an area substantially proximate the intersection of the leading edge or the trailing edge with the first end and the second end (both terminals can be near the same edge).
[0031] Figure 5 A side view of a strip 123 (e.g., a casting strip) and a cell wall 111 having a cutout 113 is shown according to various embodiments. According to various embodiments, space can be seen on either side of the connecting strip 125 in the cutout (i.e., the strip width 129 can be less than the cutout width 117). Additionally, the strip can be sized to allow space (or headroom 137) above the strip, i.e., in various embodiments, the cutout height 115 can be less than the cutout height 127 of the connecting strip 125.
[0032] Figure 6 A side cross-sectional view of a battery having the casting strip (strip 123) is shown in accordance with various embodiments. Figure 6The connecting strip 125 can be seen on the tab of the left-hand side of the cutaway battery 101. In various embodiments, the terminal post and end strip 131 can be seen, the terminal post protruding through the battery cover 105. According to various embodiments, a common head space 137 can be seen between the side of the connecting strip 125 in the cutout 137 and the battery cover 105. According to various embodiments of the present invention, Figure 6 A cell wall 111 is shown having a groove through which the connecting or casting strap is disposed to connect adjacent battery cell elements, forming an open space or head space 137 between the strap 125 and the cell cover 105. According to various embodiments, Figure 6 The head space 137 shown in should be understood to result in a common head space 137 within the battery 101 .
[0033] According to various embodiments, the common headspace can be created by making the size of the connecting (casting) band 125 smaller than the size of the recessed portion or cutout 113 of the cell partition wall 111. Thus, in various embodiments, a path of open headspace 137 is formed between the cells, and a common space is formed between the housing 103 and the cover 105.
[0034] The common headspace 137 can provide certain advantages for the functionality and lifespan of the battery. For example, the common headspace 137 can allow gases to escape more easily from the battery. While the common headspace 137 is shown on one cell as an example, it should be understood that in various embodiments, the common headspace 137 is present at each cell wall 111. The common headspace 137 can be defined by the cutout 113 and the lid 105. The band width 129 and band height 127 of the connecting band 125 can be smaller than the cutout width 117 or the cutout height 115. This allows for more space around the band 125.
[0035] Figure 7 Also shown is an isometric view of a battery 101 having the battery straps 123 or conductive straps according to various embodiments. The battery includes a battery housing 103. The straps may be "cast" where the straps are cast onto the tabs of the battery element tabs. Five connecting straps 125 are provided at Figure 7 Six battery elements 109 are shown coupled in series. In the example shown, a positive terminal and a negative terminal are shown on one side of the battery 101, which are integrally formed in the end band 131. The connecting band 125 is Figure 7113 to connect adjacent cell elements in series. Similarly, in various embodiments, the ribbon can be seen to have a thickness or ribbon height 127 such that the cell wall 111 and the cutout 113 are taller than the ribbon, and the cutout height 115 is greater than the ribbon height 127. Furthermore, the cutout 113 can be seen to have a cutout width 117 that is greater than the ribbon width 129. In various embodiments, the ribbon 123 can be seen to connect the tab of the negative battery plate of a first cell element to the tab of the positive battery plate of a second cell element.
[0036] from Figure 8 As can be seen, a cutout 113 or groove can be provided for the battery strap 125, which can be found in a single location along each battery cell wall 111. In various embodiments, it can be seen that the cutout location is appropriately positioned relative to the location of the lug and connecting strap 125. It can be seen that the positioning of the strap and cutout forms an alternating pattern. Although a single cutout or groove is specifically disclosed, more than one cutout is also contemplated. In various embodiments, it will be understood that the strap is cast through the cutout or hole in the wall. The battery strap can be sized smaller than the cutout or groove in the cell wall (i.e., the connecting strap width 129 can be smaller than the cutout width 117). This can advantageously allow further open space in the battery cavity.
[0037] Figure 9 A side view of the connecting strip 125 according to various embodiments is shown. Furthermore, according to various embodiments, it can be seen that the size of the cutout 113 is larger than the size of the connecting strip 125 in all dimensions.
[0038] As is well known in the art, the various elements of the battery, the battery housing, the battery cover and the cell container can be made of a variety of materials. For example, the cover, the container and / or the various components can be made of any polymer (e.g., polyethylene, polypropylene, a material containing polypropylene, etc.) or composite material (e.g., glass reinforced polymer). For example, the container can be made of a material containing polypropylene (e.g., pure polypropylene, a copolymer containing polypropylene, polypropylene with additives, etc.). Such polymer materials have relative resistance to degradation caused by acids (e.g., sulfuric acid) provided within the container unit. The terminal post, the side terminal and the connecting member can be made of one or more conductive materials (e.g., lead or a lead-containing material). Similarly, the band member and the end band can be made of one or more conductive materials (e.g., lead or a lead-containing material).
[0039] In various embodiments, the strip member may comprise a lead alloy. In various embodiments, the alloy may be substantially pure lead, and in various embodiments, may include lead, tin, antimony, calcium, and combinations thereof. As non-limiting examples, the alloy may be a lead-tin alloy, wherein the tin content ranges from 1-4%, 1-2.25%, 1-1.5%, and the like. In various embodiments, the lead may be raw lead, high-purity lead, or highly purified recycled lead.
[0040] The battery strap can be cast directly onto the battery cell elements. Thus, the strap can couple the tabs of the battery plates together, with the coupled battery plates forming a battery cell element, which includes a positive plate and a negative plate. As described above, a separator can be provided between the positive plate and the negative plate. As previously described, the strap can connect the positive plates or the negative plates together. The strap can have an elongated body shape to properly couple adjacent battery cell elements together by passing through grooves provided in the cell walls.
