Definitions
- the present application relates to the field of battery modules and battery packs.
- Some battery modules have used a rigid housing to reduce the battery cell expansion.
- Other battery modules have used bands fitted with tensioning buckles to reduce cell expansion.
- buckles may increase costs as well as the profile of the battery module, thereby requiring additional packaging space.
- a battery module having a battery cell stack including a plurality of sealed electrochemical cells interposing a first and a second end cover, the first end cover including a band engagement section.
- the battery module may further include a retention band circumnavigating the battery cell stack, first end cover, and second end cover, the retention band joined at an overlapping portion and including an engagement end mated with the band engagement section.
- the engagement end of the band may be formed via a crimping action to an otherwise un-modified end of the band, such as via a crimping tool.
- the crimping action may form various protrusions that are shaped to mate with corresponding recesses in the band engagement section of the first end cover.
- standardized banding material may be cut at various lengths and used to join various sized stacks, while still achieving reliable banding and tensioning at reduced costs, such as without any buckles in one example.
- a method for assembly a battery module including a first and a second end cover interposing a battery cell stack may include matting an engagement end of a retention band in a band engagement section included in the first end cover, circumnavigating a periphery of the battery module with the retention band, tensioning the retention band to a desired level, and joining a first portion of the retention band to a second portion of the retention band.
- a low profile retention band may be used to reduce cell expansion during operation of the battery module, thereby increasing the battery module's performance. Additionally, the mated band engagement section and engagement end enables a desired level of tensioning to be provided to the retention band during installation.
- Fig. 1 illustrates a battery module including a battery cell stack.
- Fig. 2 shows an exploded view of a portion of the battery cell stack shown in Fig. 1.
- Figs. 3-5 show multiple views of an engagement end of a retention band.
- Fig. 6 shows a side view of an end cover that may be included in the battery module shown in Fig. 1.
- Figs. 7-11 show an assembly process for the battery module.
- Fig. 12 shows a method for assembly of a battery module.
- Fig. 13 shows an illustration of a vehicle in which the battery module shown in Fig. 1 may be used.
- Fig. 1 shows a battery module 1 including a battery cell stack 10 interposed between a first end cover 12 and a second end cover 14.
- the battery cell stack may include a plurality of stacked and sealed electrochemical cells. The stacked arrangement allows the battery cells to be densely packed in the battery module, described in more detail herein with regard to Fig. 2.
- Retention bands 16 may circumnavigate an exterior of battery module 1. As depicted the retention bands extend down the sides of the battery cell stack in a longitudinal direction and wrap around the first and second end covers in a vertical direction. However, it will be appreciated that other retention band arrangements are possible. For example, the retention bands may wrap around the end covers in a lateral direction and extend longitudinally down the sides of the battery cell stack. Furthermore, it will be appreciated that an alternate number of retention bands may be used in other embodiments. For example, a single retention band may be used.
- the retention bands may exert opposing compressive forces on the battery module to maintain the cell stack together, and may further operate to maintain the shape of the pack when the battery cells are distended due high temperature and/or high voltage conditions.
- the retention bands may limit, and in some cases substantially inhibit, expansion of the cells within the battery module, thereby improving the battery module's efficiency.
- the opposing compressive forces may be exerted on the end covers in a longitudinally inward direction.
- the compression force may be distributed to battery cell stack via the end covers, enabling the compression force to be evenly distributed to the battery cell stack.
- the opposing compressive forces may also be exerted on the battery cells stack in a vertically inward direction.
- opposing compressive forces may also be exerted on the battery module to secure the end covers to the battery cell stack while the cells are not experiencing elevated pressures. The desired amount of compressive force may be applied during assembly of the battery module when the retention bands are joined together, described in greater detail herein with regard to Figs. 7-11.
- the retention bands may be welded together at overlapping portions 17. However other techniques may be used to join the retention bands, such as adhesive bonding. It will be appreciated that the welded retention bands have a low profile and increase the compactness of the battery module, when compared to other coupling devices, such as buckles.
- An engagement end of each retention band may be mated with a corresponding band engagement section in the one and/or both of the first and second end covers. This attachment form allows the retention bands to be coupled to, and retained by, the first end cover during installation and tensioning. Specifically, the mating of the retention bands with the first end cover may reduce slipping of the retention bands during tensioning.
- the retention bands and corresponding installation process are discussed in greater detail herein with regard to Figs. 3-11.
- the battery module may further include terminals 18, enabling energy or current to be provided to and extracted from battery module 1. In this way the battery module may be discharged and recharged.
- any single battery pack has a given number of cells
- different packs for different applications may have different numbers of cells.
- system requiring increase charge capacity may have a greater number of cells interposed between the end covers than systems with less capacity.
- the length of the bands may vary from application to application, yet due to the attachment structure described herein, it is possible to simply cut the various lengths from a single roll of banding material.

Battery cells 212 and 216 are arranged with their terminals in alignment and exposed. Compliant pad 214 is interposed between battery cell 212 and battery cell 216. However, in other examples the compliant pad may not be included in the battery cell stack.
- Housing heat sink 210 may be formed by a metal plate having a base 228 with the edges bent up 90 degrees on one or more sides to form a flanged edge.
- longitudinally aligned edge 230 and vertically aligned edges 232 are bent flanged edges.
- the housing heat sink is sized to receive one or more battery cells.
- one or more battery cells may be positioned within base 228.

- other arrangements are possible in other embodiments.
- One of the longitudinally aligned edges 232 of the housing heat sink 210 may form a portion of the top side 234 of battery module 1, as shown in Fig. 1. Similarly, one of the longitudinally aligned edges 232 may form a portion of the bottom side of the battery module.
