Description

[0001] This application is a divisional application. The application number of the original application is 202211159996.1, and the original application date is September 22, 2022. The entire contents of the original application are incorporated into this application by reference. Technical Field

[0002] The present invention relates to a battery module, and in particular to an immersion-cooled battery module. Background Art

[0003] The development of electric vehicles is progressing rapidly. In order to improve fast charging and slow discharging capabilities, it is important to manage the heat generated during charging and discharging.

[0004] Currently, there are two types of conventional cooled battery packs: non-modular cooled battery packs and modular cooled battery packs. Non-modular cooled battery packs may encapsulate multiple battery packs in a large liquid tank, which may make the battery pack bulky and heavy. Therefore, non-modular cooled battery packs are difficult to adopt on vehicle platforms of various sizes. Modular cooled battery packs can solve the above-mentioned problems of non-modular cooled battery packs by making the liquid tank modular (for example, by enclosing each battery pack in a separate liquid container). However, modular cooled battery packs may require more connectors (for example, electrical, mechanical, and liquid connectors) between modules. Therefore, the manufacture of modular cooled battery packs may be problematic due to additional material costs, complex manufacturing processes, and potential reliability issues associated with such battery packs. In addition, another problem with conventional modular cooled battery modules is that various specification parameters related to the battery, such as overall size, shape, voltage, and current, may not be the same for various application areas of the battery.

[0069] The following disclosure contains specific information related to the exemplary embodiments in the present disclosure. The drawings in the present disclosure and the detailed disclosure attached thereto are only for exemplary embodiments. However, the present disclosure is not limited to these exemplary embodiments. Other variations and embodiments of the present disclosure will occur to those skilled in the art. Unless otherwise stated, the same or corresponding components in the drawings may be represented by the same or corresponding reference numerals. In addition, the drawings and illustrations in the present disclosure are generally not drawn to scale and are not intended to correspond to actual relative sizes.

[0070] For the purpose of consistency and ease of understanding, similar features are identified by numbers in the exemplary figures (although not shown in some examples). However, features in different embodiments may differ in other aspects and should not be narrowly limited to those in the figures.

[0071] The present disclosure uses phrases such as "in one embodiment," "in some embodiments," etc., which may each refer to one or more of the same or different embodiments. The term "coupled" is defined as connected directly or indirectly through intermediate components, and is not necessarily limited to physical connections. The term "includes" means "including but not necessarily limited to;" it specifically indicates open inclusion or membership in the above combinations, groups, series, and equivalents.

[0072] In addition, for purposes of explanation and non-limiting, specific details such as functional entities, technologies, protocols, standards, etc. are set forth to provide an understanding of the described technology. In other instances, detailed disclosure of well-known methods, technologies, systems, architectures, etc. is omitted to avoid obscuring the disclosure with unnecessary details.

[0073] Figure 1is a schematic diagram of an example battery module 10 according to one embodiment of the present disclosure. The battery module 10 includes a battery housing 100 and a plurality of battery packs installed in the battery housing 100. The battery housing 100 may have a front plate 101 and a back plate 102. The battery housing 100 may also include a fluid inlet 151, a fluid outlet 152, and a plurality of housing interfaces. In some embodiments, the battery housing 100 may also include a battery housing (not shown) covered by two battery plates (e.g., a front plate 101 and a back plate 102), and the battery pack may be installed in the battery housing. In some embodiments, the fluid inlet 151 may be provided at the bottom of the front plate 101, and the fluid outlet 152 may be provided at the top of the front plate 101. Therefore, the fluid may flow into the battery module 10 from the bottom and flow out of the battery module 10 from the top of the battery module 10.

[0074] In some embodiments, the number of battery packs may be greater than or equal to two. For example, the number of battery packs may be equal to two, three, four, or other positive numbers. Figure 1 As shown, the number of battery packs may be equal to four, and the battery packs may be first to fourth battery packs 110-140. In some embodiments, the number of housing interfaces may be greater than or equal to two, and greater than or equal to the number of battery packs. For example, the number of housing interfaces may be equal to two, three, four, five, six, or another positive number. Figure 1 In the embodiment, the number of shell interfaces may be equal to eight, and the shell interfaces may be the first to eighth shell interfaces 1011-1018. Figure 1 In the embodiment, the number of housing interfaces 1011 - 1018 may be twice the number of battery packs 110 - 140 because each battery pack 110 - 140 may correspond to two of the housing interfaces 1011 - 1018 .

[0075] In some embodiments, a fluid inlet 151 may be provided on the front plate 101 to allow fluid to flow into the battery housing 100. A fluid outlet 152 may be provided on the front plate 101 to allow fluid to flow out of the battery housing 100. In some embodiments, the fluid inlet 151 may be provided on the outer surface of the front plate 101 to allow fluid to flow into the battery housing 100, and the fluid outlet 152 may be provided on the outer surface of the front plate 101 to allow fluid to flow out of the battery housing 100. The battery module 10 may be coupled to a fluid cooling thermal management system (not shown). The fluid may flow from the fluid cooling thermal management system into the battery module 10 through the fluid inlet 151. When the fluid flows into the battery module 10, the battery pack 110-140 may be immersed in the fluid. The fluid cooling thermal management system may control the temperature of the battery module 10 through the fluid to prevent the battery module 10 from overheating. After flowing through the entire battery module 10, the fluid may flow out of the battery module 10 through the fluid outlet 152 and return to the fluid cooling thermal management system.

[0076] In some embodiments, the housing interfaces 1011-1018 may be disposed on the front plate 101. In some embodiments, the housing interfaces 1011-1018 may be disposed on the outer surface of the front plate 101. In addition, each battery pack 110-140 may have a plurality of group electrodes. In some embodiments, the number of group electrodes in one of the battery packs may be greater than or equal to two. For example, the number of group electrodes in one of the battery packs may be equal to two, four, six, or other positive numbers. Figure 1 As shown, the number of group electrodes of one of the battery groups 110-140 can be equal to two. Therefore, the first battery group 110 can have a first group of electrodes 1101 and a second group of electrodes 1102, the second battery group 120 can have a third group of electrodes 1201 and a fourth group of electrodes 1202, the third battery group 130 can have a fifth group of electrodes 1301 and a sixth group of electrodes 1302, and the fourth battery group 140 can have a seventh group of electrodes 1401 and an eighth group of electrodes 1402.

[0077] In some embodiments, each group electrode can be coupled to one of the housing interfaces, and each housing interface can be coupled to one of the group electrodes. Therefore, when the number of group electrodes per battery group is equal to two, the number of housing interfaces can be twice the number of battery groups. Figure 1As shown, each group electrode 1101, 1102, 1201, 1202, 1301, 1302, 1401, and 1402 can be respectively coupled to only one of the housing interfaces 1011-1018, and each housing interface 1011-1018 can be respectively coupled to only one of the group electrodes 1101, 1102, 1201, 1202, 1301, 1302, 1401, and 1402. Therefore, the number of housing interfaces 1011-1018 can be twice the number of battery packs 110-140.

[0078] In some embodiments, each shell interface can be coupled to at least one group electrode respectively. When a specific one of the shell interfaces is coupled to more than one group electrode, the specific shell interface can further include more than one interface area. Each of the more than one interface areas in the specific shell interface can be coupled to one of the more than one group electrodes. For example, the specific shell interface can have two interface areas and be coupled to two group electrodes. Therefore, each of the two interface areas in the specific shell interface can be coupled to one of the two group electrodes. Therefore, the number of shell interfaces in the battery module 10 can be equal to two, three, four, five or other positive numbers. For example, the battery module 10 may include two battery packs 110 and 120 and three shell interfaces. In some embodiments, one of the two group electrodes in the battery pack 110 can be coupled to one of the three shell interfaces, one of the two group electrodes in the battery pack 120 can be coupled to another of the three shell interfaces, and the other of the two group electrodes of the battery pack 110 and the other of the two group electrodes of the battery pack 120 can be coupled to the last of the three shell interfaces. In some embodiments, the size of a housing interface coupled to more than one set of electrodes can be larger than the size of another housing interface coupled to only one set of electrodes.

[0079] In some embodiments, the group electrode may be exposed to the outside of the front plate 101. In some embodiments, the group electrode may be exposed to the outside of the outer surface of the front plate 101. In some embodiments, the shell interface may be a plurality of interface holes on the front plate 101, and each group electrode may pass through one of the shell interfaces respectively. Therefore, since the group electrode directly penetrates the shell interface to be exposed to the outside of the front plate 101, the group electrode may be directly exposed to the outside of the front plate 101. For example, the shell interfaces 1011-1018 may be interface holes on the front plate 101, and each group electrode 1101, 1102, 1201, 1202, 1301, 1302, 1401 and 1402 may pass through one of the shell interfaces 1011-1018 of the front plate 101 respectively. Therefore, the group electrodes 1101 , 1102 , 1201 , 1202 , 1301 , 1302 , 1401 , and 1402 may be exposed to the outside of the front plate 101 from the interface holes.

[0080] In some embodiments, the housing interface may be a plurality of connector interfaces on the front plate 101, and each group electrode may be electrically coupled to one of the plurality of connector interfaces. Therefore, since each group electrode is engaged to one of the housing interfaces, each group electrode of the battery pack may be electrically exposed to the outside of the front plate 101. For example, the housing interfaces 1011-1018 may be connector interfaces on the front plate 101, and each group electrode 1101, 1102, 1201, 1202, 1301, 1302, 1401, and 1402 may be electrically coupled to one of the plurality of connector interfaces. Therefore, since each of the group electrodes 1101, 1102, 1201, 1202, 1301, 1302, 1401 and 1402 can be bonded to one of the housing interfaces 1011-1018, the group electrodes 1101, 1102, 1201, 1202, 1301, 1302, 1401 and 1402 of the battery packs 110-140 can be electrically exposed to the outside of the front plate 101.

The battery module 10 includes a battery housing 100 and a plurality of battery packs 110-140 mounted in the battery housing 100. The battery housing 100 may have a front plate 101 and a back plate 102. The front plate 101 of the battery housing 100 may further include a fluid inlet 151, a fluid outlet 152, and a housing interface (not shown).

To clearly illustrate the electrical connections of the battery module 10, Figure 1 Omitted Figure 2A and Figure 2B At least one flow control member is shown, but Figure 1 The battery housing 100 still includes at least one Figure 2A and Figure 2B The flow control member shown.

[0082] In some embodiments, each of the at least one flow control member may be disposed between two of the plurality of battery packs 110-140 to control the flow of fluid through a fluid channel (not shown) between two of the plurality of battery packs 110-140. In some embodiments, each of the at least one flow control member may be a sealing member adjacent to one of the front plate 101 and the back plate 102 to block the fluid channel between two adjacent battery packs. The number of at least one flow control member may be determined based on the number of battery packs. For example, the number of at least one flow control member may be determined by subtracting one from the number of battery packs. Therefore, when the number of battery packs is equal to two, the number of at least one flow control member may be equal to one. In addition, when the number of battery packs is greater than two, the number of at least one flow control member may be greater than one.

[0083] In some embodiments, the battery packs 110-140 may include first to fourth bottom covers 111, 121, 131, and 141, first to fourth top covers 112, 122, 132, and 142, first to fourth battery holders 113, 123, 133, and 143, and a plurality of first to fourth battery cells 114, 124, 134, and 144. The battery cells 114, 124, 134, and 144 may be carried by a corresponding one of the battery holders 113, 123, 133, and 143, respectively.

In some embodiments, the sealing member is a separator member inserted into the battery housing 100 to block the fluid passage between two adjacent battery packs in the plurality of battery packs 110-140. In some embodiments, when the fluid passage is adjacent to the front plate 101 and positioned away from the back plate 102, the fluid passage may be a front passage. In addition, when the fluid passage is adjacent to the back plate 102 and positioned away from the front plate 101, the fluid passage may be a rear passage.

The fourth flow control member 164 may be inserted between the first top cover 112 of the first battery group 110 and the second bottom cover 121 of the second battery group 120 to block the front passage between the two adjacent battery groups 110 and 120, the fifth flow control member 165 may be inserted between the second top cover 122 of the second battery group 120 and the third bottom cover 131 of the third battery group 130 to block the rear passage between the two adjacent battery groups 120 and 130, and the sixth flow control member 166 may be inserted between the third top cover 132 of the third battery group 130 and the fourth bottom cover 141 of the fourth battery group 140 to block the front passage between the two adjacent battery groups 130 and 140.

[0089] In some embodiments, a portion of at least one flow control member in the battery housing 100 may be a blocker, and other flow control members in the at least one flow control member in the battery housing 100 may be a separator member. For example, to produce the battery module 10, the fourth flow control member 164 adjacent to the front plate 101 may be disposed between the first battery group 110 and the second battery group 120 to block the front channel between the two adjacent battery groups 110 and 120.

[0092] In some embodiments, each of the bottom covers 111, 121, 131, and 141 may include a corresponding one of the lower surfaces 171, 173, 175, and 177, and each of the top covers 112, 122, 132, and 142 may include a corresponding one of the upper surfaces 172, 174, 176, and 178. In some embodiments, a first front opening 1711 adjacent to the front plate 101 may be located at the lower surface 171 of the battery pack 110, and a first rear opening 1712 away from the front plate 101 and adjacent to the back plate 102 may be located at the lower surface 171 of the battery pack 110.

Since the battery packs 110 and 120 are two adjacent battery packs, the first front opening 1731 corresponds to the second front opening 1721 to generate the front channel 1701. In addition, a first rear opening 1732 away from the front plate 101 and adjacent to the back plate 102 may be located at the lower surface 173 of the battery pack 120, and a second rear opening 1722 away from the front plate 101 and adjacent to the back plate 102 may be located at the upper surface 172 of the battery pack 110. Since the battery packs 110 and 120 are two adjacent battery packs, the first rear opening 1732 corresponds to the second rear opening 1722 to generate the rear channel 1702.

[0094] In some embodiments, since the battery packs 120 and 130 are two adjacent battery packs, the first front opening 1751 located at the lower surface 175 of the battery pack 130 corresponds to the second front opening 1741 located at the upper surface 174 of the battery pack 120 to generate the front channel 1703, and the first rear opening 1752 located at the lower surface 175 of the battery pack 130 corresponds to the second rear opening 1742 located at the upper surface 174 of the battery pack 120 to generate the rear channel 1704. In some embodiments, since the battery packs 130 and 140 are two adjacent battery packs, the first front opening 1771 located at the lower surface 177 of the battery pack 140 corresponds to the second front opening 1761 located at the upper surface 176 of the battery pack 130 to generate the front channel 1705, and the first rear opening 1772 located at the lower surface 177 of the battery pack 140 corresponds to the second rear opening 1762 located at the upper surface 176 of the battery pack 130 to generate the rear channel 1706.

[0095] In some embodiments, the flow control member may be a sealing member covering the first front opening 1731 and the second front opening 1721 to prevent fluid from flowing through the front channel 1701 adjacent to the front plate 101. In one embodiment, the first flow control member 161 may be positioned away from the first rear opening 1732 and the second rear opening 1722 to allow fluid to flow through the rear channel 1702 positioned away from the front plate 101. In other embodiments, the fourth flow control member 164 may include a baffle opening 1641 for the first rear opening 1732 and the second rear opening 1722 to allow fluid to flow through the rear channel 1702 positioned away from the front plate 101. In some embodiments, the flow control member may be a sealing member covering the first rear opening 1752 and the second rear opening 1742 to prevent fluid from flowing through the rear channel 1704 adjacent to the back plate 102. In one embodiment, the second flow control member 162 may be positioned away from the first front opening 1751 and the second front opening 1741 to allow fluid to flow through the front channel 1703 positioned away from the back plate 102. In other embodiments, the fifth flow control member 165 may include a baffle opening 1651 for the first front opening 1751 and the second front opening 1741 to allow fluid to flow through the front channel 1703 positioned away from the back plate 102.

[0096] In some embodiments, the back plate 102 is located at the opposite end of the battery module 10 when viewed from the front plate 101. Figure 3A In the embodiment, each of the flow control members 161-163 is adjacent to one of the front plate 101 and the back plate 102, and is positioned away from the other of the front plate 101 and the back plate 102. For example, the flow control members 161 and 163 are adjacent to the front plate 101, and are positioned away from the back plate 102. In addition, the flow control member 162 is adjacent to the back plate 102, and is positioned away from the front plate 101.

[0097] In some embodiments, when the number of the at least one flow control member is greater than one, one of the plurality of battery packs may be sandwiched between two adjacent flow control members of the at least one flow control member. In addition, when one of the two adjacent flow control members is adjacent to the back plate 102, the other of the two adjacent flow control members is adjacent to the front plate 101. Figure 2A and Figure 3A As shown, the battery pack 120 may be sandwiched between two adjacent flow control members 161 and 162. When the second flow control member 162 is adjacent to the back plate 102, the first flow control member 161 is adjacent to the front plate 101. In addition, the battery pack 130 may be sandwiched between two adjacent flow control members 162 and 163. When the second flow control member 162 is adjacent to the back plate 102, the third flow control member 163 is adjacent to the front plate 101.

[0098] In some embodiments, at least one flow control member may be a partition member inserted between two adjacent battery groups for separating the two adjacent battery groups from each other. In addition, the fluid passage is kept unobstructed by the partition opening of the partition member so that the fluid flows from one of the two adjacent battery groups to the other of the two adjacent battery groups through the partition opening. Further reference Figure 2B and Figure 3B As shown, the fourth flow control member 164 may be a partition member inserted between the battery packs 110 and 120 for separating the battery packs 110 and 120 from each other, and the rear channel 1702 is kept unobstructed by the partition opening 1641 of the fourth flow control member 164, so that the fluid flows from the battery pack 110 to the battery pack 120 through the partition opening 1641. The partition opening 1641 may be positioned away from the front plate 101 and adjacent to the back plate 102.

[0099] In addition, the fifth flow control member 165 may be a partition member inserted between the battery groups 120 and 130 for separating the battery groups 120 and 130 from each other, and the front channel 1703 is kept unobstructed by the partition opening 1651 of the fifth flow control member 165 so that the fluid flows from the battery group 120 to the battery group 130 through the partition opening 1651. The partition opening 1651 may be located away from the back plate 102 and adjacent to the front plate 101. In addition, the sixth flow control member 166 may be a partition member inserted between the battery groups 130 and 140 for separating the battery groups 130 and 140 from each other, and the rear channel 1706 is kept unobstructed by the partition opening 1661 of the sixth flow control member 166 so that the fluid flows from the battery group 130 to the battery group 140 through the partition opening 1661. The partition opening 1661 may be located away from the front plate 101 and adjacent to the back plate 102.

[0100] In some embodiments, when the number of at least one flow control member is greater than one, one of the plurality of battery packs may be sandwiched between two adjacent flow control members of the at least one flow control member. Each of the two adjacent flow control members includes a partition opening so that the fluid flows through the partition opening. In addition, when one of the two partition openings of the two adjacent flow control members is close to the back plate 102, the other of the two partition openings of the two adjacent flow control members is close to the front plate 101. Figure 2B and Figure 3B As shown, the battery pack 120 may be sandwiched between two adjacent flow control members 164 and 165. When the partition opening 1641 of the fourth flow control member 164 is adjacent to the back plate 102, the partition opening 1651 of the fifth flow control member 165 is adjacent to the front plate 101. In addition, the battery pack 130 may be sandwiched between two adjacent flow control members 165 and 166. When the partition opening 1661 of the sixth flow control member is adjacent to the back plate 102, the partition opening 1651 of the fifth flow control member 165 is adjacent to the front plate 101.

[0101] refer to Figure 2A , Figure 2B , Figure 3A and Figure 3B , the fluid can flow into the fluid inlet 151 and flow out of the battery housing 100 from the fluid outlet 152. In addition, the front channel 1701 can be blocked and the rear channel 1702 remains unobstructed. Therefore, before the fluid flows from the battery pack 110 to the battery pack 120 through the rear channel 1702, the battery pack 110 can be filled with the fluid and the fluid can flow through all the battery cells 114 in the battery pack 110. Similarly, before the fluid flows from the battery pack 120 to the battery pack 130 through the front channel 1703, the battery pack 120 can be filled with the fluid and the fluid can flow through all the battery cells 124 in the battery pack 120. Before the fluid flows from the battery pack 130 to the battery pack 140 through the rear channel 1706, the battery pack 130 can be filled with the fluid and the fluid can flow through all the battery cells 134 in the battery pack 130. Before the fluid flows out of the battery housing 100 from the battery pack 140 through the fluid outlet 152, the battery pack 140 may be filled with the fluid, and the fluid may flow through all the battery cells 144 in the battery pack 140. Therefore, the fluid may flow through all the battery packs 110-140 in sequence. Therefore, the temperature control of the battery cells 114, 124, 134, and 144 may be improved and the temperature distribution of the battery cells 114, 124, 134, and 144 may be uniform.

[0102] In some embodiments, reference Figure 2B and Figure 3B, the number of battery packs may be equal to three, five, seven or more. In some embodiments, the battery module 10 may include two flow control members to separate two adjacent battery packs, and the two flow control members may have a partition opening, respectively. In addition, one of the partition openings of the two flow control members separating the two adjacent battery packs may be adjacent to the front plate 101, and the other of the two flow control members may be adjacent to the back plate 102. For example, two flow control members may be provided between the battery packs 110 and 120. In some embodiments, one of the two flow control members between the battery packs 110 and 120 may include a partition opening adjacent to the back plate 102, and the other of the two flow control members between the battery packs 110 and 120 may include a partition opening adjacent to the front plate 101. Therefore, the component entrance for the battery pack 120 may still be adjacent to the front plate 101. In some embodiments, two flow control members may also be provided between the battery packs 120 and 130, and the component entrance for the battery pack 130 may still be adjacent to the front plate 101. However, the assembly outlet of the battery pack 130 may be adjacent to the back plate 102. In some embodiments, in order to ensure that the fluid can flow out of the battery module 10 from the fluid outlet 152, a flow control member may be provided above the battery pack 130. Therefore, the fluid may flow out of the battery pack 130 from the partition opening of the flow control member above the battery pack 130, and then flow out of the battery module 10 through the fluid outlet 152.

[0103] In some embodiments, Figure 2B and Figure 3BAs shown, the number of battery groups may be equal to three, five, seven or more. In some embodiments, the battery module 10 may include a flow control member to separate two adjacent battery groups, and the flow control member may have one or two partition openings. In some embodiments, when a flow control member separating two adjacent battery groups has a partition opening, the partition opening may be adjacent to the back plate 102. In addition, when a flow control member separating two adjacent battery groups has two partition openings, one of the two partition openings may be adjacent to the back plate 102, and the other of the two partition openings may be adjacent to the front plate 101. In some embodiments, for example, the battery module 10 may include three battery groups 110-130. There may be a flow control member 164 separating battery groups 110 and 120 and another flow control member 165 separating battery groups 120 and 130. The flow control member 164 may include a partition opening 1641 adjacent to the back plate 102, and the flow control member 165 may include two partition openings 1651 adjacent to the front plate 101 and the back plate 102, respectively. Therefore, before the fluid flows from the battery pack 110 to the battery pack 120 through the rear channel 1702, the battery pack 110 can be filled with the fluid, and the fluid can flow through all the battery cells 114 in the battery pack 110. In some embodiments, since the two partition openings 1651 are adjacent to the front plate 101 and the back plate 102, respectively, the fluid can flow into the battery pack 130 through the front channel 1703 and the rear channel 1704. Since the fluid can flow into the battery pack 130 through the rear channel 1704, the fluid can still completely flow through the battery cell 134 adjacent to the back plate 102. In addition, since the fluid can flow out of the battery pack 120 through the front channel 1703, the fluid can still completely flow through the battery cell 124 adjacent to the front plate 101. Therefore, the fluid can completely flow through the battery cells 114, 124, and 134 to efficiently control the temperature of the battery module 10.

The number of group electrodes in one of the battery packs may be equal to two, four, six, or other positive numbers. In some embodiments, each shell interface 2011-2014 may be coupled to a group electrode in the battery pack, and each group electrode in the battery pack may be coupled to one of the shell interfaces 2011-2014. Therefore, when each battery pack includes two group electrodes, there may be two battery packs installed in the battery housing 200.

[0106] In some embodiments, the battery housing 200 can be installed by a battery housing 203 and two battery plates. A battery pack having group electrodes can be installed in the battery housing 203. The two battery plates can be coupled to the battery housing 203 to cover the battery pack. The two battery plates can be a front plate 201 and a back plate 202. One of the two battery plates may include a fluid inlet 251, a fluid outlet 252, and a housing interface 2011-2014, which are respectively arranged on the outer surface of one of the two battery plates. In some embodiments, the battery housing 203 can be integrated with the back plate 202. When the battery pack is installed in the battery housing 203, the front plate 201 can cover the battery housing 203 to produce a battery module 20. In some embodiments, the battery housing 203 can be integrated with the front plate 201. When the battery pack is installed in the battery housing 203, the back plate 202 can cover the battery housing 203 to generate a battery module 20.

The battery module 20 may include a battery housing 200 and a plurality of battery packs mounted in the battery housing 200. The battery housing 200 may also include a front plate 201 and a back plate 202. The battery housing 200 may also include a fluid inlet 251, a fluid outlet 252, and housing interfaces 2011-2014.

[0108] In some embodiments, the number of battery packs may be greater than or equal to two. Figure 5 In the embodiment, the number of battery packs may be equal to two, and the battery packs may be a first battery pack 210 and a second battery pack 220 .

[0109] In some embodiments, each of the battery packs 210 and 220 may also include a plurality of group electrodes, each group electrode coupled to one of the housing interfaces 2011-2014. In some embodiments, the number of group electrodes in each battery pack may be greater than or equal to two. For example, the number of group electrodes in one of the battery packs may be equal to two, four, six, or another positive number. Figure 5, the first battery group 210 may include a first group electrode 2101 and a second group electrode 2102, and the second battery group 220 may include a third group electrode 2201 and a fourth group electrode 2202. Therefore, the number of group electrodes in each of the battery groups 210 and 220 may be equal to two, and the number of group electrodes in the battery module 20 may be equal to four.

[0110] In some embodiments, each housing interface 2011-2014 can be coupled to only one of battery packs 210 and 220 and to only one of pack electrodes 2101, 2102, 2201, and 2202. In addition, each pack electrode 2101, 2102, 2201, and 2202 can also be coupled to only one of housing interfaces 2011-2014.

[0111] refer to Figure 4A and Figure 5 , when the battery module 20 is connected to the fluid cooling thermal management system, the fluid can flow into the battery module 20 through the fluid inlet 251. The fluid can flow through the battery pack 210 and then flow into the battery pack 220. After the fluid flows through the battery packs 210 and 220, the fluid can flow out of the battery module 20 through the fluid outlet 252. In some embodiments, in order to ensure that the fluid can flow through each battery cell of the battery packs 210 and 220, the fluid inlet 251 and the fluid outlet 252 can be located at different ends of the diagonal line of the front plate 201, and the fluid inlet 251 can be located below the fluid outlet 252. For example, the fluid inlet 251 can be located at the lower left corner of the front plate 201, and the fluid outlet 252 can be located at the upper right corner of the front plate 201.

[0112] Fig. 6A Showing an embodiment according to the present disclosure Figure 5 2 is a side view of battery packs 210 and 220 and front plate 201 shown in FIG. Figure 6B Showing an embodiment according to the present disclosure Fig. 6A Magnified view of region A shown in FIG.

[0113] In some embodiments, reference Fig. 6A and Figure 6B, the first battery pack 210 may include a first front opening 2711 and a first rear opening 2712 both located on the lower surface 271 of the battery pack 210, and a second front opening 2721 and a second rear opening 2722 both located on the upper surface 272 of the battery pack 210. In addition, the second battery pack 220 may include a first front opening 2731 and a first rear opening 2732 both located on the lower surface 273 of the battery pack 220, and a second front opening 2741 and a second rear opening 2742 both located on the upper surface 274 of the battery pack 220. In some embodiments, the first front openings 2711 and 2731 and the second front openings 2721 and 2741 may be located adjacent to the front plate 201, while the first rear openings 2712 and 2732 and the second rear openings 2722 and 2742 may be located away from the front plate 201. Figure 5 As shown, the first rear openings 2712 and 2732 and the second rear openings 2722 and 2742 may be located adjacent to the back plate 202 .

[0114] In some embodiments, when the battery packs 210 and 220 are mounted with the front plate 201 , the first front opening 2731 may face the second front opening 2721 to create the front channel 2701 , and the first rear opening 2732 may face the second rear opening 2722 to create the rear channel 2702 .

[0115] In some embodiments, the flow control member 261 may be a sealing member located near the front plate 201 to block the fluid passage between the battery packs 210 and 220. Therefore, since the flow control member 261 is disposed on the front plate 201, the front passage 2701 generated by the first front opening 2731 and the second front opening 2721 may be blocked. Figure 4A As shown, when the fluid flows into the battery module 20, the flow control member 261 can be a blocker that prevents the fluid from flowing through the front channel 2701. Therefore, the fluid can fill the battery pack 210 and then can flow from the battery pack 210 to the battery pack 220 through the rear channel 2702.

[0116] In some embodiments, when the number of battery packs in the battery module is greater than two, at least one flow control member may be provided on the back plate 202. For example, when the number of battery packs in the battery module is greater than six, three blockers may be provided on the front plate 201, and two blockers may be provided on the back plate 202. When the blocker is provided on the back plate 202, the rear channel generated by the first rear opening and the second rear opening may be blocked.

[0117] Figure 7A partial exploded view of a battery module according to one embodiment of the present disclosure is shown. The battery module 20 may include a battery housing 200, a plurality of battery packs 210 and 220 mounted in the battery housing 200, and a flow control member 264 inserted between the battery packs 210 and 220. The flow control member 264 may be a sealing member to block the fluid passage between the battery packs 210 and 220. The battery housing 200 may also include a front plate 201 and a back plate 202. The battery housing 200 may also include a fluid inlet 251, a fluid outlet 252, and housing interfaces 2011-2014.

[0118] In some embodiments, the number of battery packs may be greater than or equal to two. Figure 7 In the embodiment, the number of battery packs may be equal to two, and the battery packs may be a first battery pack 210 and a second battery pack 220 .

[0119] In some embodiments, each of the battery packs 210 and 220 may further include a plurality of group electrodes, each group electrode coupled to one of the housing interfaces 2011-2014. In some embodiments, the number of group electrodes of a portion of the battery packs may be greater than or equal to two. Figure 7 In the embodiment, the number of group electrodes in each battery group 210 and 220 may be equal to two, and the number of group electrodes in the battery module 20 may be equal to four. In some embodiments, each housing interface 2011-2014 may be coupled to only one of the battery groups 210 and 220, and to only one of the group electrodes 2101, 2102, 2201, and 2202. In addition, each group electrode 2101, 2102, 2201, and 2202 may also be coupled to only one of the housing interfaces 2011-2014.

[0120] refer to Figure 4A and Figure 7 , when the battery module 20 is connected to the fluid cooling thermal management system, the fluid can flow into the battery module 20 through the fluid inlet 251. The fluid can flow through the battery pack 210 and then flow into the battery pack 220. After the fluid flows through the battery packs 210 and 220, the fluid can flow out of the battery module 20 through the fluid outlet 252. In some embodiments, the fluid inlet 251 and the fluid outlet 252 can be located at different ends of the diagonal line of the front plate 201, and the fluid inlet 251 can be located below the fluid outlet 252.

[0121] Fig. 8A Showing an embodiment according to the present disclosure Figure 7 20, a side view of battery packs 210 and 220, flow control member 264, and front plate 201 are shown in FIG. Figure 8B Showing an embodiment according to the present disclosure Fig. 8AMagnified view of region B shown in FIG.

[0122] In some embodiments, Fig. 8A and Figure 8B As shown, the first battery pack 210 may include a first front opening 2711 and a first rear opening 2712 both located on the lower surface 271 of the battery pack 210, and a second front opening 2721 and a second rear opening 2722 both located on the upper surface 272 of the battery pack 210. In addition, the second battery pack 220 may include a first front opening 2731 and a first rear opening 2732 both located on the lower surface 273 of the battery pack 220, and a second front opening 2741 and a second rear opening 2742 both located on the upper surface 274 of the battery pack 220.

[0123] In some embodiments, when the battery packs 210 and 220 are mounted with the front plate 201 , the first front opening 2731 may face the second front opening 2721 to create a front channel 2701 , and the first rear opening 2732 may face the second rear opening 2722 to create a rear channel 2702 .

[0124] In some embodiments, the flow control member 264 may be a sealing member inserted between the battery packs 210 and 220 to block the fluid passage between the battery packs 210 and 220. Therefore, when the flow control member 264 is inserted from the front plate 201, the front channel 2701 created by the first front opening 2731 and the second front opening 2721 may be blocked. Figure 4A , when the fluid flows into the battery module 20, the flow control member 264 may be a baffle member to prevent the fluid from flowing through the front channel 2701. In addition, the length of the flow control member 264 may be shorter than the length of the battery packs 210 and 220, so that the flow control member 264 may be too short to further block the rear channel 2702 generated by the first rear opening 2732 and the second rear opening 2722. Therefore, the fluid may fill up the battery pack 210, and then may flow from the battery pack 210 to the battery pack 220 through the rear channel 2702.

[0125] In some embodiments, when the number of battery packs in the battery module is greater than two, at least one flow control member may be inserted from the back plate 202. For example, when the number of battery packs in the battery module is greater than six, three separator members may be inserted from the front plate 201 and two separator members may be inserted from the back plate 202. When the separator member is inserted from the back plate 202, the rear channel created by the first rear opening and the second rear opening may be blocked. In addition, the separator member may be too short to further block the front channel created by the first front opening and the second front opening.

[0126] Fig. 9A Showing an embodiment according to the present disclosure Figure 7 2 is a side view of battery packs 210 and 220, flow control member 264, and front plate 201 shown in FIG. Fig. 9B and Fig. 9C is a schematic diagram of an example flow control member having baffle openings according to one embodiment of the present disclosure.

[0127] In some embodiments, reference Fig. 9A , the first battery pack 210 may include a first front opening 2711 and a first rear opening 2712 both located at the lower surface 271 of the battery pack 210, and a second front opening 2721 and a second rear opening 2722 both located at the upper surface 272 of the battery pack 210. In addition, the second battery pack 220 may include a first front opening 2731 and a first rear opening 2732 both located at the lower surface 273 of the battery pack 220, and a second front opening 2741 and a second rear opening 2742 both located at the upper surface 274 of the battery pack 220.

[0128] In some embodiments, when the battery packs 210 and 220 are mounted with the front plate 201 , the first front opening 2731 may face the second front opening 2721 to create a front channel 2701 , and the first rear opening 2732 may face the second rear opening 2722 to create a rear channel 2702 .

[0129] In some embodiments, the flow control member 264 may be a sealing member inserted between the battery packs 210 and 220 to block the fluid passage between the battery packs 210 and 220. Therefore, when the flow control member 264 is inserted from the front plate 201, the front channel 2701 generated by the first front opening 2731 and the second front opening 2721 may be blocked. Figure 4A As shown, when the fluid flows into the battery module 20, the flow control member 264 may be a baffle member to prevent the fluid from flowing through the front channel 2701. In addition, although the length of the flow control member 264 may be the same as the length of the battery packs 210 and 220, the flow control member 264 may include a baffle opening adjacent to the back plate 202 so that the fluid flows through the flow control member 264. Therefore, the fluid can fill the battery pack 210 and then can flow from the battery pack 210 to the battery pack 220 through the rear channel 2702.

[0130] In some embodiments, when the number of battery packs in the battery module is greater than two, there may be at least one flow control member inserted from the back plate 202. For example, when the number of battery packs in the battery module is greater than six, there may be three separator members inserted from the front plate 201 and two separator members inserted from the back plate 202. When the separator member is inserted from the back plate 202, the rear channel created by the first rear opening and the second rear opening may be blocked. In addition, the separator opening adjacent to the front plate 201 may allow fluid to flow through the front channel created by the first front opening and the second front opening.

[0131] In some embodiments, Fig. 9B In some embodiments, the baffle opening 2641 can be a rectangular slit on the flow control member 264. Fig. 9C In the embodiment, the baffle opening can be an elliptical slit on the flow control member 264. In some embodiments, when the baffle opening 2641 is adjacent to the back plate 202, the baffle opening 2641 can be connected to the rear channel 2702 to allow the fluid to flow through the rear channel 2702. In addition, when the baffle opening is adjacent to the front plate 201, the baffle opening can be connected to the front channel to allow the fluid to flow through the front channel.

[0132] Fig.10 Showing an embodiment according to the present disclosure Figure 5 3D structural diagram of two battery packs 210 and 220 shown in . In some embodiments, battery pack 210 may include a bottom cover 211, a top cover 212, a battery holder, a plurality of battery cells 214, and a plurality of group electrodes, and battery pack 220 may include a bottom cover 221, a top cover 222, a battery holder, a plurality of battery cells 224, and a plurality of group electrodes. In some embodiments, the battery holder of battery pack 210 may include a bottom battery holder 2131 and a top battery holder 2132, and the battery holder of battery pack 220 may include a bottom battery holder 2231 and a top battery holder 2232. In a specific embodiment, the number of group electrodes may be equal to or greater than two. For example, in Fig.10 In some embodiments, battery pack 210 may have two group electrodes 2101 and 2102 , and battery pack 220 may have two group electrodes 2201 and 2202 .

[0133] In some embodiments, the bottom battery holder 2131 may be mounted below the battery cell 214, and the top battery holder 2132 may be mounted above the battery cell 214. Thus, the battery cell 214 may be sandwiched between and supported by the bottom battery holder 2131 and the top battery holder 2132. In some embodiments, the bottom cover 211 may be mounted below the bottom battery holder 2131, and the top cover 212 may be mounted above the top battery holder 2132. Thus, the bottom battery holder 2131, the battery cell 214, and the top battery holder 2132 may be sandwiched between the bottom cover 211 and the top cover 212.

[0134] In some embodiments, the battery packs 210 and 220 may each have one of a plurality of monitoring components 215 and 225. The monitoring component 215 may be used to monitor the operating state of the battery pack 210, and the monitoring component 225 may be used to monitor the operating state of the battery pack 220. In some embodiments, the operating state may include voltage data, current data, and temperature data.

[0135] Fig.11 Showing an embodiment according to the present disclosure Fig.10 220 is an exploded view of the battery pack 220 shown in FIG. In some embodiments, reference Fig.10 , battery pack 220 may further include bottom wiring member 2251, top wiring member 2252, bottom connector member 2261, top connector member 2262, and a plurality of support members 227. In some embodiments, bottom battery holder 2231, battery cell 224, and top battery holder 2232 may be sandwiched between bottom connector member 2261 and top connector member 2262. In addition, bottom connector member 2261 may be mounted above bottom cover 221, and top connector member 2262 may be mounted below top cover 222. In some embodiments, battery cell 224 may be a lithium-ion battery cell or any other rechargeable battery.

[0136] In some embodiments, the bottom battery holder 2231 may include a plurality of base holes 22310, and the top battery holder 2232 may include a plurality of top holes 22320. Each base hole 22310 may be aligned with one of the top holes 22320. The battery cell 224 may be inserted into the base holes 22310 and the top holes 22320 to be fixed to the bottom battery holder 2231 and the top battery holder 2232. Since each base hole 22310 is aligned with one of the top holes 22320, the battery cell 224 may be vertically fixed to the bottom battery holder 2231 and the top battery holder 2232.

[0137] In some embodiments, at least one of the bottom connector member 2261 or the top connector member 2262 can include a plurality of connector openings. In some embodiments, the bottom connector member 2261 can include a plurality of bottom connector openings 22610. In some embodiments, the top connector member 2262 can include a plurality of top connector openings 22620. When the bottom connector member 2261 includes the bottom connector openings 22610, each base hole 22310 can be aligned with one of the bottom connector openings 22610. When the top connector member 2262 includes the top connector openings 22620, each top seat hole 22320 can be aligned with one of the top connector openings 22620.

[0138] In some embodiments, the bottom connector member 2261 can be installed under the bottom battery holder 2231 to connect with the battery cell 224, and electrically connected to the battery cell 224 through a plurality of connecting members (not shown). Each connecting member can pass through a corresponding one of the base holes 22310 and a corresponding one of the bottom connector openings 22610 to connect a corresponding one of the battery cells 224 to the bottom connector member 2261, respectively.

[0139] In some embodiments, the top connector member 2262 can be installed above the top battery holder 2232 to connect with the battery cell 224, and form an electrical connection with the battery cell 224 through a plurality of connecting members (not shown). Each connecting member can pass through a corresponding one of the top holder holes 22320 and a corresponding one of the top connector openings 22620 to connect a corresponding one of the battery cells 224 to the top connector member 2262, respectively.

[0140] In some embodiments, the connection member may include a plurality of adapters. In some embodiments, the connector member may include a plurality of connection lines.

[0141] In some embodiments, at least one of the bottom connector member 2261 or the top connector member 2262 can include a group electrode. Fig.11 In the embodiment of the present invention, the bottom connector member 2261 may include two sets of electrodes 2201 and 2202. Fig.10 , the top connector member of the battery pack 210 may include two group electrodes 2101 and 2102. Since at least one of the bottom connector member 2261 or the top connector member 2262 is electrically coupled to the battery cell 224, the group electrode may also be electrically coupled to the battery cell 224 and further coupled to one of the housing interfaces 2011-2014. Figure 5 , Fig.10 and Fig.11 , the two group electrodes 2101 and 2102 of the top connector component of the battery pack 210 can be electrically coupled to the housing interfaces 2011 and 2012, while the two group electrodes 2201 and 2202 of the bottom connector component 2261 can be electrically coupled to the housing interfaces 2013 and 2014.

[0142] In some embodiments, bottom wiring member 2251 can be mounted on bottom battery holder 2231 and electrically connected to bottom connector member 2261, and top wiring member 2252 can be mounted on top battery holder 2232 and electrically connected to top connector member 2262. In some embodiments, bottom wiring member 2251 can be mounted directly on bottom connector member 2261, and top wiring member 2252 can be mounted directly on top connector member 2262. In some embodiments, referring to Fig.10 , monitoring member 215 may be electrically connected to bottom wiring member 2251 and top wiring member 2252. Since bottom wiring member 2251 and top wiring member 2252 are electrically connected to bottom connector member 2261 and top connector member 2262 that are electrically connected to battery cell 224, monitoring member 215 may receive a plurality of signals from battery cell 224 to monitor the operating status of battery pack 220. In some embodiments, bottom wiring member 2251 and top wiring member 2252 may further include a temperature sensing circuit for detecting the temperature of bottom connector member 2261 and top connector member 2262. Therefore, the received signal may also include the temperature.

[0143] In some embodiments, in order to prevent fluid disturbance from being generated in the battery module due to bottom wiring member 2251 and top wiring member 2252, bottom wiring member 2251 and top wiring member 2252 may be flexible printed circuits (FPCs) instead of a plurality of cables. When bottom wiring member 2251 and top wiring member 2252 are cables, the cables may be distributed in battery housing 200. Therefore, the flow direction of the fluid may be disturbed, thereby possibly reducing the cooling efficiency. When bottom wiring member 2251 and top wiring member 2252 are FPCs, the FPCs may be flat and fixed to bottom battery holder 2231 and top battery holder 2232. Therefore, the flow direction of the fluid is not affected by bottom battery holder 2231 and top battery holder 2232, and thus the cooling efficiency is not affected by bottom battery holder 2231 and top battery holder 2232. When monitoring components 215 and 225 do not receive data of the operating status (e.g., particularly voltage data), battery module 20 may not operate normally. To maintain stable operation, bottom wiring member 2251 and top wiring member 2252 may be fixed to bottom battery holder 2231 and top battery holder 2232 by at least one of a ribbon bond or a screw-fastened copper sheet. For example, screws may be used to fix the copper sheet to bottom wiring member 2251 and bottom battery holder 2231, and a ribbon bond may be further applied to couple the copper sheet to bottom battery holder 2231. In one embodiment, the ribbon bond may be applied with hard gold.

[0144] In some embodiments, the support member 227 may be installed between the bottom battery holder 2231 and the top battery holder 2232. The support member 227 may be installed in parallel with the battery core 224 to provide support strength for the weight of components of the battery pack 220.

[0145] In some embodiments, the bottom cover 221 and the top cover 222 can be used to protect the battery pack 220. For example, the bottom cover 221 and the top cover 222 can provide protection for the ribbon joints in the battery pack 220 from direct contact or external damage from the environment. In some embodiments, the bottom cover 221 and the top cover 222 can control the lateral flow of fluid and prevent the fluid from flowing directly and vertically out of the battery pack 220 from the top battery seat 2232.

[0146] Fig.12 Showing an embodiment according to the present disclosure Fig.11 The top battery holder 2232 further includes a plurality of top holder holes 22320 , a plurality of top interference members 22321 , a plurality of top fluid holes 22322 , a plurality of top wall members 22323 and a plurality of top rib members 22324 .

[0147] In some embodiments, the top seat holes 22320 can be used to hold the battery cells 224. In some embodiments, each top interference member 22321 can be formed in one of the top seat holes 22320. The top interference member 22321 can protrude slightly from the inner surface (not shown) of the top seat hole 22320. For example, each top interference member 22321 can include an extended protrusion or rib. Therefore, further reference Fig.11 The top interference member 22321 can provide interference force to the battery cell 224 inserted into the top seat hole 22320, so that when an accident occurs, it is difficult for the battery cell 224 to be removed from the top interference member 22321. In some embodiments, the base hole 22310 of the bottom battery seat 2231 may further include a plurality of bottom interference members (not shown) slightly protruding from the inner surface (not shown) of the base hole 22310.

[0148] In some embodiments, the battery pack 210 may further include a top interference member and a bottom interference member. In some embodiments, even without the top interference member in the top battery holder 2232, the interference amount of the bottom interference member may be high enough to stabilize the battery cell 224. In some embodiments, the interference amount in the top interference member may be low relative to the interference amount in the bottom interference member, so that the battery cell 224 can be easily assembled into the top battery holder 2232. In some embodiments, the interference amount in the top interference member may be equal to the interference amount in the bottom interference member.

[0149] In some embodiments, when fluid flows into the battery pack 220, the fluid may flow through the top fluid hole 22322 to flow out of the battery pack 220. In addition, when the fluid flows into the battery pack 220, the fluid may flow through the plurality of bottom fluid holes (not shown) of the bottom battery seat 2231 to flow near the battery cells 224 to control the temperature of the battery cells 224. The top fluid hole 22322 may be adjacent to the top seat hole 22320. In some embodiments, each of the top fluid holes 22322 may be adjacent to at least three of the top seat holes 22320, and each of the top seat holes 22320 may be adjacent to at least three of the top fluid holes 22322. Fig.12In some embodiments, three adjacent top seat holes 22320 may surround one of the top fluid holes 22322 located at the center of the three adjacent top seat holes 22320, and three adjacent top fluid holes 22322 may surround one of the top seat holes 22320 located at the center of the three adjacent top fluid holes 22322. In some embodiments, each top fluid hole 22322 may include at least one through hole. For example, the number of at least one through hole in one of the top fluid holes 22322 may be equal to one, two, three or more. In some embodiments, the top fluid hole 22322 may be smaller than the top seat hole 22320. In some embodiments, each of the bottom fluid holes may be adjacent to at least three of the base holes 22310, and each of the base holes 22310 may be adjacent to at least three of the bottom fluid holes. In some embodiments, each of the bottom fluid holes may include at least one through hole. In some embodiments, battery pack 210 may also include a top fluid hole and a bottom fluid hole.

[0150] In some embodiments, the top wall member 22323 can protrude from an upper surface (not shown) of the top battery holder 2232. Figure 5 , the top wall member 22323 may be perpendicular to the front plate 201 and the back plate 202. The top wall member 22323 can guide the fluid to flow in the direction of the top wall member 22323. Therefore, the fluid can be evenly distributed and flow in the battery pack 220. In some embodiments, the bottom battery holder 2231 may also include a plurality of bottom wall members (not shown). The bottom wall member may protrude from the lower surface (not shown) of the bottom battery holder 2231. In addition, the bottom wall member of the bottom battery holder 2231 may also be perpendicular to the front plate 201 and the back plate 202. In some embodiments, the number of top wall members 22323 may be different from the number of bottom wall members. For example, the number of top wall members 22323 may be equal to two, and the number of bottom wall members may be equal to three. In some embodiments, the battery pack 210 may also include a top wall member and a bottom wall member.

[0151] In some embodiments, the top rib members 22324 may be located on both sides of the top battery seat 2232.

[0160] Fig.15 Showing an embodiment according to the present disclosure Fig.14A Schematic diagram of an example connection relationship between the bottom connector member 2261 and the top connector member 2262 shown in. In some embodiments, the bottom connector member 2261 may include four bottom connector plates 2271-2274, and the top connector member 2262 may include three top connector plates 2275-2277.

[0162] In some embodiments, bottom connector plate 2271 may correspond to top connector area 22751 to produce a first battery area including a first portion of battery cell 224, bottom connector area 22721 may correspond to top connector area 22752 to produce a second battery area including a second portion of battery cell 224, bottom connector area 22722 may correspond to top connector area 22761 to produce a third battery area including a third portion of battery cell 224, bottom connector area 22731 may correspond to top connector area 22762 to produce a fourth battery area including a fourth portion of battery cell 224, bottom connector area 22732 may correspond to top connector area 22771 to produce a fifth battery area including a fifth portion of battery cell 224, and bottom connector plate 2274 may correspond to top connector area 22772 to produce a sixth battery area including a sixth portion of battery cell 224. In some embodiments, the directions of the first, third, and fifth portions of the battery cells 224 may be the same as each other, the directions of the second, fourth, and sixth portions of the battery cells 224 may be the same as each other, and the directions of the first, third, and fifth portions of the battery cells 224 may be different from the second, fourth, and sixth portions of the battery cells 224. Therefore, the battery cells 224 may be connected in series or in parallel to each other through the bottom connector member 2261 and the top connector member 2262. For example, the battery cells 224 corresponding to the same top connector region and the same bottom connector region may be coupled in parallel to each other, and the battery cells 224 corresponding to different top connector regions and different bottom connector regions may be coupled in series to each other.

[0163] In some embodiments, both the group electrodes 2201 and 2202 can be disposed in one of the bottom connector member and the top connector member. For example, the group electrodes 2201 and 2202 can be disposed on the bottom connector member 2261. In some embodiments, both the group electrodes 2201 and 2202 can be disposed in one of the bottom connector plate and the top connector plate to form an L-shaped connector plate. In addition, the long side of the L-shaped connector plate can be the connector plate of the connector member, and the short side of the L-shaped connector plate can be one of the group electrodes.

[0164] In some embodiments, the bottom connector member of the battery pack 210 can be identical to the top connector member 2262 of the battery pack 220, and the top connector member of the battery pack 210 can be identical to the bottom connector member 2261 of the battery pack 220.

In some embodiments, the direction of the battery cell 214 may be the same as the reverse direction of the battery cell 224.

[0165] In some embodiments, the number of battery cells in a battery pack may be equal to Nc. In some embodiments, the bottom connector member of the battery pack may be divided into a plurality of bottom connector regions. The number of bottom connector regions in the bottom connector member of the battery pack may be equal to Nr. Therefore, the number of battery cells in each bottom connector region may be equal to the value Np calculated by dividing the number Nc by the number Nr. In some embodiments, the arrangement of the battery cells may be regarded as (Nr)S(Np)P. For example, the number of battery cells Nc may be equal to 180 and the number of bottom connector regions Nr in the bottom connector member may be equal to 6. Therefore, the number of battery cells Np regions in each bottom connector may be equal to 30, and the arrangement of the battery cells may be regarded as 6S30P. In some embodiments, when the number of battery cells Nc may be equal to 180, the arrangement of the battery cells may include 6S30P, 4S45P, 12S15P, and 10S18P.

[0166] In some embodiments, the arrangement of the battery cells may be determined based on the output current requirement of the battery pack. If the output current requirement increases, the number of battery cells Np in each bottom connector area of ​​the battery pack may be increased. In other words, referring to Fig.15 The connection relationship between the bottom connector member and the top connector member can be changed based on the number Nr of bottom connector areas in the bottom connector member of the battery pack. In addition, the wall members of the bottom battery holder and the top battery holder can also be changed based on the number Nr of bottom connector areas in the bottom connector member of the battery pack.

[0167] For example, the arrangement of the battery cells may be 4S45P. Therefore, the bottom connector member may include three bottom connector plates, and the middle bottom connector plate of the three bottom connector plates may be divided into two bottom connector areas. In addition, the top connector member may include two top connector plates, each of which is divided into two top connector areas. The number of top connector areas may be equal to four, and the number of battery cells corresponding to one of the four top connector areas may be equal to 45.

[0168] In some embodiments, the bottom connector board can be divided into a bottom connector area along a first direction, and the top connector board can be divided into a top connector area along the first direction. In some embodiments, the bottom connector board can be divided into a bottom connector area along a second direction, and the top connector board can be divided into a top connector area along the second direction. In an embodiment, the first direction can be different from the second direction. In some embodiments, the first direction can be perpendicular to the second direction. In some embodiments, the bottom connector board can be divided into a bottom connection area along the first direction and the second direction, and the top connector board can be divided into a top connection area along the first direction and the second direction. For example, Fig.15 The bottom connector member 2261 and the top connector member 2262 in the embodiment can be further divided in the horizontal direction to produce more connector areas. For example, there may be twelve top connector areas in the top connector member 2262.

[0169] In some embodiments, one of the group electrodes 2201 and 2202 can be disposed on the bottom connector member 2261, and the other of the group electrodes 2201 and 2202 can be disposed on the top connector member 2262. For example, the group electrode 2201 can be disposed on the bottom connector member 2261, and the group electrode 2202 can be disposed on the top connector member 2262. In some embodiments, referring to Figure 5 , when each of the group electrodes 2201 and 2202 is disposed on a different connector member, two of the four group electrodes in the battery module can be exposed to the outside of the two corners of the front plate 201. However, in order to maintain the uniformity of the fluid flow, the fluid inlet 251 and the fluid outlet 252 can also be disposed at the two corners of the front plate 201. Therefore, one of the four group electrodes and one of the fluid inlet 251 and the fluid outlet 252 can be disposed at the same corner of the front plate 201. In some embodiments, one of the four group electrodes can be further coupled to a connector interface disposed near one of the fluid inlet 251 and the fluid outlet 252 for exposure to the outside of the front plate 201.

[0170] In some embodiments, the bottom connector member 2261 and the top connector member 2262 can be divided into Nr bottom connector areas and Nr top connector areas. Each of the Nr bottom connector areas can correspond to one of the Nr top connector areas, which is used to define Nr groups of battery cells 224. In some embodiments, when the number Nc of battery cells is equal to 180, the arrangement of battery cells may include 1S180P, 3S60P, 5S36P, and 9S20P. In some embodiments, when the number Nr is equal to one, one of the battery connector members can be connected to the positive pole of the battery module, and another of the battery connector members can be connected to the negative pole of the battery module. In some embodiments, when the number Nr is greater than one, one of the connector areas of one of the battery connector members can be connected to the positive pole of the battery module, and one of the connector areas of another of the battery connector members can be connected to the negative pole of the battery module.

[0171] In some embodiments, for example, the arrangement of the battery cells can be 3S60P. Therefore, the bottom connector member can include two bottom connector plates, and the right side one of the two bottom connector plates can be divided into two bottom connector areas. In addition, the top connector member can also include two top connector plates, and the left side one of the two bottom connector plates can be divided into two bottom connector areas. The number of top connector areas can be equal to three, and the number of battery cells corresponding to one of the three top connector areas can be equal to 60. In some embodiments, the directions of the battery cells 224 of the first and third parts can be the same as each other and different from the direction of the battery cells 224 of the second part. In order to accommodate the directions of the first, second and third parts for the battery cells 224, the group electrode 2201 can be set on the bottom connector member 2261, and the group electrode 2202 can be set on the top connector member 2262.

[0172] In some embodiments, the group electrodes 2201 and 2202 can be arranged at different connector components or the same connector component to accommodate different arrangements of the battery core. In some embodiments, the battery module can provide flexibility in the voltage or current range of the battery pack. Therefore, under certain shared components of similar structure, the battery module can adapt to various specifications of electrical output.

[0173] Fig.16A A perspective structural diagram of a battery case shown in FIG. 4 according to one embodiment of the present disclosure is shown. Fig. 16B and Fig. 16C Front views of the battery case and the front plate shown in FIG. 4 are respectively shown according to one embodiment of the present disclosure.

For example, the battery housing 203 may be similar to a box having at least four outer plates 2030. In some embodiments, the shape of the battery housing 203 may be a square tube or a rectangular tube. Due to cost requirements, the extrusion method of the battery housing 203 may be used for mass production. The battery housing 203 may be made of aluminum or other materials.

[0175] In some embodiments, further referring to FIG4 , the battery case 203 may include four outer plates 2030 to create a receiving space 2031 covered by the front plate 201 and the back plate 202.

In some embodiments, the battery case 203 may include five outer plates 2030 to create a receiving space 2031 covered by the front plate 201.

[0176] In some embodiments, the outer plate 2030 of the battery housing 203 may include an outer surface 2032 and an inner surface 2033. The outer surface 2032 may further include a plurality of outer protruding lines 20321, and the inner surface 2033 may further include a plurality of inner protruding lines 20331 and a plurality of inner protruding units 20332. In some embodiments, some of the outer protruding lines 20321 on the upper surface of the outer surface 2032 may further include hanging holes 20322. The hanging holes 20322 may be used to connect with a lifting tool to facilitate the transportation of the battery module.

[0177] In some embodiments, reference Fig. 16B , the outer protruding lines 20321 may protrude from the outer surfaces 2032 of the four outer plates 2030. In addition, the inner protruding lines 20331 and the inner protruding units 20332 may protrude from the inner surfaces 2033 of two of the four outer plates 2030. In some embodiments, two of the four outer plates 2030 may be two side plates of the battery case 203.

[0178] In some embodiments, each of the outer protruding lines 20321 may extend along a straight line and be parallel to each other. In some embodiments, each outer protruding line 20321 may be a long rib extending from a front end (not shown) of the outer panel 2030 to a rear end (not shown) of the outer panel 2030. Referring to FIG. 4 , the front end of the outer panel 2030 may be covered by the front panel 201, and the rear end of the outer panel 2030 may be covered by the back panel. In some embodiments, one of the outer protruding lines 20321 may include a plurality of short ribs arranged along a single straight line, and may protrude from the outer surface 2032, respectively. For example, one of the outer protruding lines 20321 may include two short ribs aligned with each other along a single straight line, and may protrude from the front end and the rear end of the outer surface 2032, respectively. In some embodiments, some outer protruding lines 20321 may include long ribs extending from the front end to the rear end, while other outer protruding lines 20321 may include short ribs distributed along a corresponding straight line.

[0179] In some embodiments, each of the inner protrusion line 20331 and the inner protrusion unit 20332 may also extend along a straight line and be parallel to each other. In some embodiments, each of the inner protrusion line 20331 and the inner protrusion unit 20332 may also be a long rib extending from the front end to the rear end. In some embodiments, one of the inner protrusion lines 20331 may include a plurality of short ribs aligned with each other along a single straight line, and may protrude from the inner surface 2033, respectively. In some embodiments, one of the inner protrusion units 20332 may include a plurality of short ribs aligned with each other along another straight line, and may protrude from the inner surface 2033, respectively. For example, one of the inner protrusion line 20331 and the inner protrusion unit 20332 may include two short ribs aligned with each other along a single straight line, and may protrude from the front end and the rear end of the inner surface 2033, respectively. In some embodiments, some of the inner protrusion lines 20331 and the inner protrusion units 20332 may include long ribs extending from the front end to the rear end, while other inner protrusion lines 20331 and the inner protrusion units 20332 may include short ribs distributed along a corresponding one of the straight lines.

[0180] In some embodiments, two adjacent inner protrusion lines 20331 may form a track 20341. Thus, the inner surface 2033 may include a plurality of tracks 20341 generated from the inner protrusion lines 20331. Fig.11 As shown, each rail 20341 can correspond to one of the battery holders, such as the bottom battery holder 2131 and the top battery holder 2132.

[0181] In some embodiments, two adjacent inner protrusion units 20332 may form an inner flow slit 20342. Therefore, the inner surface 2033 may include a plurality of inner flow slits 20342 generated from the inner protrusion units 20332. Figure 6B , the inner flow slit 20342 can be used to accommodate the flow control member 261. In other words, the flow control member 261 can be inserted into the inner flow slit 20342 to block the fluid passage between two adjacent battery packs. Figure 6B In the embodiment, the flow control member 261 may be a sealing member to be inserted into the inner flow slit 20342. Since the flow control member 261 may be an obstruction, the inner flow slit 20342 may be two small slits respectively formed on both sides of the battery housing 203. Therefore, the inner protrusion unit 20332 may be two pairs of protrusions respectively protruding from both sides of the battery housing 203. Therefore, when the flow control member 261 is an obstruction, the inner protrusion unit 20332 may not extend from the front end to the rear end.

[0182] In some embodiments, reference Figure 7 , the inner flow slit 20342 can be used to accommodate the flow control member 264. In other words, the inner flow slit 20342 can be inserted by the flow control member 264 to block the fluid passage between two adjacent battery packs. Figure 7 , the flow control member 264 may be a sealing member to be inserted into the inner flow slit 20342. Since the flow control member 264 may be a separator member, the inner flow slit 20342 may be two inner flow tracks respectively formed on both sides of the battery case 203. Therefore, the inner protrusion unit 20332 may be two pairs of protrusion lines respectively protruding from both sides of the battery case 203. Therefore, when the flow control member 264 is a separator member, the inner protrusion unit 20332 may extend from the front end to the rear end.

[0183] In some embodiments, referring to FIG4 , each of the front plate 201 and the back plate 202 may have two side surfaces. In addition, the sides of the front plate 201 and the back plate 202 may also include a plurality of plate protrusions. Fig. 16B , each of the plate protrusions can correspond to one of the outer protrusion lines 20321. Therefore, each plate protrusion and the corresponding outer protrusion line 20321 can be assembled into a plurality of outer shell protrusion lines. In addition, each plate protrusion and outer protrusion line can further have a pin hole for locking the front plate 201 and the rear plate 202 with the battery housing 203. For example, a plate protrusion on the back plate 202 can be locked with a corresponding outer protrusion line to connect the back plate 202 to the battery housing 203. In some embodiments, Fig. 16CIn the embodiment, the front plate 201 may have two side surfaces 2019, and a plurality of plate protrusions 20191 may protrude from the two side surfaces 2019. In addition, each plate protrusion 20191 and the outer protrusion line 20321 may also have a sufficient thickness to form a fastening hole for a screw or a bolt. Therefore, each plate protrusion 20191 and the corresponding outer protrusion line 20321 may be assembled into a housing protrusion line.

[0184] In some embodiments, the front panel 201 may further include a plurality of panel interfaces. The number of panel interfaces may be equal to the number of battery packs in the battery module. Fig.10 and Fig. 16C , each of the monitoring components 215 and 225 may correspond to one of the board interfaces 20101 and 20102. In some embodiments, the board interfaces 20101 and 20102 may be used to expose the monitoring components 215 and 225 to the board holes outside the front plate 201. Therefore, there may be some connection lines to couple the monitoring components 215 and 225 to an external monitoring system to monitor the operating status of the battery packs 210 and 220. In some embodiments, the board interfaces 20101 and 20102 may include an internal connector for connecting to the monitoring components 215 and 225 and an external connector for connecting the monitoring components 215 and 225 to the connection lines and the external monitoring system to monitor the operating status of the battery packs 210 and 220.

[0185] In some embodiments, reference Fig.10 , Fig.11 and Fig. 16C , the monitoring member 225 may include a circuit board coupled to the bottom wiring member 2251 and the top wiring member 2252 to receive the operating status, and the circuit board is connected to an output interface (not shown) to output the operating status. The output interface may be an output connector exposed to the outside of the front plate 201, and connected to the circuit board of the monitoring member 225 through a board line. In some embodiments, one end of the board line may be coupled to the output interface, and the other end of the board line may be coupled to the circuit board of the monitoring member 225. In some embodiments, a board connector may be provided between the circuit board and the output interface to fix and stabilize the board line on the front plate 201.

[0186] Fig.17 Showing an embodiment according to the present disclosure Fig. 16B The front view of the two battery housings shown in FIG. The battery housing 203 may have an outer plate 2030 . The outer plate 2030 may include an outer surface 2032 , and the outer surface 2032 may also include an outer protruding line 20321 .

[0187] In some embodiments, further referring to FIG4 , the battery housing 303 may include four outer plates 3030 to create a receiving space 3031 to be covered by the front plate and the back plate corresponding to the battery housing 303. The receiving space 3031 can be used to accommodate a battery pack. In some embodiments, the battery housing 303 may include five outer plates 3030 to create a receiving space 3031 covered by the front plate.

[0188] In some embodiments, the protrusion height of the outer protrusion line 20321 located on the left side of the outer surface 2032 may be different from the protrusion height of the outer protrusion line 20321 located on the right side of the outer surface 2032. In some embodiments, each outer protrusion line 20321 located on the left side of the outer surface 2032 may be higher than at least one outer protrusion line 20321 located on the right side of the outer surface 2032. For example, the lowermost outer protrusion line 20321 located on the left side of the outer surface 2032 may still be higher than the lowermost outer protrusion line 20321 located on the right side of the outer surface 2032. In other embodiments, each outer protrusion line 20321 located on the left side of the outer surface 2032 may be lower than at least one outer protrusion line 20321 located on the right side of the outer surface 2032.

[0189] In some embodiments, Fig.17 In the embodiment of the present invention, the battery case 303 may be the same as the battery case 203. When the battery case 303 is joined with the battery case 203 to connect two different battery modules to each other, the outer protruding line 20321 of the battery case 203 may be joined with the outer protruding line 30321 of the battery case 303 to increase the strength of the structure between two adjacent battery modules. In some embodiments, each outer protruding line 30321 located on the left side of the outer surface 3032 may be higher than at least one outer protruding line 20321 located on the right side of the outer surface 2032. In addition, each outer protruding line 30321 located on the left side of the outer surface 3032 may be slightly higher than a corresponding outer protruding line 20321 located on the right side of the outer surface 2032. Therefore, when the battery case 303 is joined with the battery case 203, each outer protruding line 30321 located on the left side of the outer surface 3032 may be joined with a corresponding outer protruding line 20321 located on the right side of the outer surface 2032. In other words, the outer protrusion line at the side surface can be set asymmetrically with respect to the opposite side surface. Therefore, when assembling the battery module, the outer protrusion lines of adjacent battery modules are staggered, resulting in a reduced distance between the battery modules, thereby increasing the sealing of the battery system, and further improving the stability of the battery system.

[0190] In some embodiments, reference Fig. 16C and Fig.17, the front plate 201 can be connected to the battery housing 203 to produce a battery housing 200 having multiple housing protrusion lines. Therefore, the housing protrusion lines of the battery housing 200 can also be detachably coupled to other housing protrusion lines of another battery housing having the battery housing 303 to couple the battery module 20 to another battery module having another battery housing.

[0191] In some embodiments, the battery cases 203 and 303 may be stacked on each other. Therefore, each outer protruding line 20321 located at the top of the outer surface 2032 may be slightly misaligned with a corresponding outer protruding line 20321 located at the bottom of the outer surface 2032. In addition, each outer protruding line 30321 located at the top of the outer surface 3032 may be slightly misaligned with a corresponding outer protruding line 30321 located at the bottom of the outer surface 3032. In some embodiments, when the battery case 303 is installed near the battery case 203, the outer protruding line 20321 located at the top of the outer surface 2032 may be engaged with the outer protruding line 30321 located at the bottom of the outer surface 3032.

[0192] Fig.18A A three-dimensional structural diagram of a battery pack according to one embodiment of the present disclosure is shown. Fig.18B Showing an embodiment according to the present disclosure Fig. 16B A front view of the battery housing is shown in FIG. Fig.18A The battery pack 210 in Figure 5 21. The battery pack 210 in FIG. 21 has only the monitoring member 215 removed to clearly show the bottom battery holder 2131 and the top battery holder 2132.

[0193] In some embodiments, the battery pack 210 may include a bottom battery holder 2131 and a top battery holder 2132. In addition, the bottom battery holder 2131 may further include a plurality of bottom rib members 21314, and the top battery holder 2132 may further include a plurality of top rib members 21324. In some embodiments, two bottom rib members 21314 are respectively located on one of the two side surfaces of the bottom battery holder 2131, and two top rib members 21324 are respectively located on one of the two side surfaces of the top battery holder 2132.

[0194] In some embodiments, the accommodation space 2031 of the battery housing 203 may include an upper region and a lower region. Fig.10 , the battery pack 210 can be inserted into the lower area, and the battery pack 220 can be inserted into the upper area. In some embodiments, the lower area of ​​the receiving space 2031 may include a plurality of tracks. Fig.18B, the number of tracks in the lower area of ​​the accommodating space 2031 may be equal to four. In some embodiments, tracks 20341 and 20343 may be located at the same height, and tracks 20345 and 20347 may be located at the same height. In addition, the height difference between tracks 20341 and 20345 may be the same as the height difference between the bottom battery holder 2131 and the top battery holder 2132. Therefore, each track 20341, 20343, 20345, and 20347 in the lower area of ​​the accommodating space 2031 may correspond to one of the bottom rib member 21314 and the top rib member 21324 of the battery pack 210. In some embodiments, further reference is made to Fig.12 , each rail in the upper area of ​​the accommodating space 2031 may also correspond to one of the bottom rib member and the top rib member 22324 of the battery pack 220 .

[0195] In some embodiments, when the battery pack 210 is inserted into the accommodation space 2031 of the battery case 203, the two bottom rib members 21314 may be inserted into the corresponding two rails 20341 and 20343, and the two top rib members 21324 may be inserted into the corresponding two rails 20345 and 20347. In some embodiments, when the battery pack 220 is inserted into the accommodation space 2031 of the battery case 203, the two bottom rib members may be inserted into the two bottom rails in the upper region of the accommodation space 2031, and the two top rib members 22324 may be inserted into the two top rails in the upper region of the accommodation space 2031.

[0196] Fig.19A Showing an embodiment according to the present disclosure Fig.18A An enlarged view of the right side of the battery pack is shown. Fig.19B Showing an embodiment according to the present disclosure Fig.19A Magnified view of region C shown in FIG.

[0197] In some embodiments, the bottom rib member 21314 may also include a plurality of bottom lateral protrusions 21315 and a plurality of bottom vertical protrusions 21316. In addition, the top rib member 21324 may also include a plurality of top lateral protrusions 21325 and a plurality of top vertical protrusions (not shown). In some embodiments, the bottom vertical protrusions 21316 may protrude upward from the bottom rib member 21314, and the top vertical protrusions may protrude downward from the top rib member 21324. In addition, referring to Fig.18B , a bottom lateral protrusion 21315 can protrude from the bottom rib member 21314 toward the track 20343, and a top lateral protrusion 21325 can protrude from the top rib member 21324 toward the track 20347.

[0198] In some embodiments, reference Fig.18A , the left side of the bottom battery holder 2131 and the top battery holder 2132 may further include a bottom lateral protrusion, a bottom vertical protrusion, a top lateral protrusion, and a top vertical protrusion. In some embodiments, when the battery pack 210 is inserted into the battery housing 203, the bottom lateral protrusion 21315 located on the right side of the bottom battery holder 2131 and the bottom lateral protrusion located on the left side of the bottom battery holder 2131 may provide a force in the lateral direction to introduce a lateral interference fit between the bottom battery holder 2131 of the battery pack 210 and the rails 20341 and 20343 of the battery housing 203. In addition, when the battery pack 210 is inserted into the battery housing 203, the top lateral protrusion 21325 located on the right side of the top battery holder 2132 and the bottom lateral protrusion located on the left side of the bottom battery holder 2131 may also provide a force in the lateral direction to introduce a lateral interference fit between the top battery holder 2132 of the battery pack 210 and the rails 20345 and 20347 of the battery housing 203. The bottom lateral protrusion and the top lateral protrusion may include a thickness that gradually increases along an increasing direction. The increasing direction may be perpendicular to the lateral direction. In some embodiments, the battery pack 210 may be inserted along an insertion direction to be assembled into the battery module 20. In the embodiment, the increasing direction of the gradually increasing thickness may be opposite to the insertion direction. Therefore, when the battery pack 210 is inserted into the battery housing 203, the lateral interference fit between the bottom battery seat 2131 and the top battery seat 2132 of the battery pack 210 and the rails 20341, 20343, 20345 and 20347 of the battery housing 203 may increase to enhance the stability of the battery pack 210.

[0199] In some embodiments, the bottom vertical protrusion 21316 can provide a force in the vertical direction to introduce an interference fit between the bottom battery holder 2131 of the battery pack 210 and the track 20343 of the battery housing 203, and the top vertical protrusion on the right side of the top battery holder 2132 can provide a force in the vertical direction to introduce a vertical interference fit between the top battery holder 2132 of the battery pack 210 and the track 20347 of the battery housing 203. In addition, the bottom vertical protrusion on the left side of the bottom battery holder 2131 can also provide a force in the vertical direction to introduce an interference fit between the bottom battery holder 2131 of the battery pack 210 and the track 20341 of the battery housing 203, and the top vertical protrusion on the left side of the top battery holder 2132 can provide a force in the vertical direction to introduce a vertical interference fit between the top battery holder 2132 of the battery pack 210 and the track 20345 of the battery housing 203. The bottom vertical protrusion and the top vertical protrusion can include a thickness that gradually increases in an increasing direction. The increasing direction of the gradually increasing thickness may be perpendicular to the vertical direction and opposite to the insertion direction. Therefore, when the battery pack 210 is inserted into the battery housing 203, the vertical interference fit between the bottom battery holder 2131 and the top battery holder 2132 of the battery pack 210 and the rails 20341, 20343, 20345 and 20347 of the battery housing 203 may increase to enhance the stability of the battery pack 210.

[0200] In some embodiments, a bottom mounting notch may be provided between two adjacent bottom lateral protrusions 21315, and a top mounting notch may be provided between two adjacent top lateral protrusions 21325. In addition, another bottom mounting notch may be provided between two adjacent bottom vertical protrusions 21316, and another top mounting notch may be provided between two adjacent top vertical protrusions of the bottom rib member 21314. In some embodiments, some soft material may be installed into the bottom mounting notch and the top mounting notch to provide additional friction to enhance the structural strength of the assembled battery module 20.

[0201] In some embodiments, the lateral protrusions and the vertical protrusions may be staggered along the insertion direction. Thus, lateral forces and vertical forces from the lateral protrusions and the vertical protrusions may be applied to the battery housing 203 at multiple staggered locations.

[0202] Fig. 20A three-dimensional structural diagram of a battery system 9 according to an embodiment of the present disclosure is shown. The battery system 9 may include a system housing 90 and a system cover 91. The system housing 90 may have a side wall 92. The side wall 92 may also include a plurality of housing interfaces, a housing inlet 9221, and a housing outlet 9222. The housing interfaces, the housing inlet 9221, and the housing outlet 9222 are disposed on the side wall 92 of the system housing 90. In some embodiments, the distance between the housing inlet 9221 and the housing outlet 9222 may be greater than one quarter of the width of the side wall 92.

[0203] In some embodiments, the number of housing interfaces may be equal to a positive integer. For example, the number of housing interfaces may be equal to two. In some embodiments, housing inlet 9221 may be used to flow fluid into system housing 90, and housing outlet 9222 may be used to flow fluid out of system housing 90. In addition, housing interfaces 9211 and 9212 may be connected to an operating system for powering the operating system, or connected to a charging device for charging battery system 9.

[0205] Fig.21 Showing an embodiment according to the present disclosure Fig. 20 The battery system 9 shown in FIG. 1 is a three-dimensional structural diagram without a system cover. The battery system 9 can accommodate multiple battery modules. In some embodiments, the battery modules in the battery system 9 may include Figure 1 , Figure 2A , Figure 2B , Figure 3A or Figure 3B In some embodiments, the battery module in the battery system 9 may include Figure 4A , Figure 4B , Figure 5 or Figure 7 The battery module 20 is shown in FIG.

[0206] In some embodiments, the number of battery modules may be equal to a positive integer. For example, the number of housing interfaces may be equal to four. In some embodiments, the battery modules 20-50 may be installed along the installation direction. In some embodiments, reference Figure 4A The installation direction can be parallel to the front plate 201 and perpendicular to the normal direction of the front plate 201.

[0207] In some embodiments, when the fluid flows into the battery system 9 through the housing inlet 9221, the fluid may flow into the battery modules 20-50 in sequence along the installation direction, and then flow out of the battery system 9 through the housing outlet 9222. In some embodiments, the housing interfaces 9211 and 9212 may be electrically coupled to the battery modules 20-50 for powering the operating system or charging the battery modules 20-50 through a charging device. In some embodiments, the signal connector 923 may be coupled to the battery module 20-50 to receive the operating status of the battery module 20-50.

[0208] Fig. 22 A three-dimensional structural diagram showing a portion of components in a battery system according to an embodiment of the present disclosure is shown for displaying Fig. 20 The electrical connections of the battery system shown in FIG.

In some embodiments, the fifth housing connector 935 may be used to couple the fourth bottom battery group to the fourth top battery group in the battery module 50. In some embodiments, the sixth housing connector 936 may be used to couple the fourth top battery group with the third top battery group in the battery module 40, the seventh housing connector 937 may be used to couple the third top battery group with the second top battery group in the battery module 30, the eighth housing connector 938 may be used to couple the second top battery group with the first top battery group in the battery module 20, and the housing interface 9212 may be coupled to the ninth housing connector 939 to couple to the first top battery group.

[0210] In some embodiments, a system switch 924 disposed on the side wall 92 may be coupled between the chassis interface 9212 and the ninth chassis connector 939 to allow a user to manually disconnect the battery system 9 .

[0211] In some embodiments, the signal connector 923 can be coupled to a computing system to receive the operating status of the battery system 9. The signal connector 923 can be coupled to a monitoring board 925, which is coupled to the monitoring components 20-50 of the battery modules for receiving the operating status of the battery modules 20-50. Fig.10 , the monitoring board 925 can be coupled to the monitoring components 215 and 225 of the battery module 20 to receive the operating status of the battery packs 210 and 220 of the battery module 20. In some embodiments, the operating status may include voltage data, current data, and temperature data of the battery modules 20-50. In some embodiments, the operating status can be monitored by the monitoring components 215 and 225, and the monitoring board 925 can also output data to other systems through the signal connector 923. For example, the monitoring board 925 can output data to a computer of a vehicle having the battery system 9. In some embodiments, the monitoring board 925 can be a battery control unit (BCU).

[0212] In some embodiments, the battery modules can be stacked on each other. For example, the battery module 50 can be arranged above the battery module 40, the battery module 40 can be arranged above the battery module 30, and the battery module 30 can be arranged above the battery module 20. In some embodiments, the housing interface 9211 can be coupled to the first housing connector 931 to couple to the first bottom battery pack, and the housing interface 9212 can be coupled to the ninth housing connector 939 to couple to the fourth top battery pack. In some embodiments, the second housing connector 932, the fourth housing connector 934, the sixth housing connector 936, and the eighth housing connector 938 can be used to couple multiple battery packs in a corresponding one of the battery modules 20-50, respectively. For example, the fourth housing connector 934 can be used to connect multiple battery packs in the battery module 30. In some embodiments, the third housing connector 933, the fifth housing connector 935, and the seventh housing connector 937 may be used to respectively connect a top battery pack of one of the battery modules 20-50 and a bottom battery pack of another battery module 20-50 disposed above the one of the battery modules 20-50. For example, the seventh housing connector 937 may be used to connect the top battery pack in the battery module 40 to the bottom battery pack in the battery module 50.

[0213] In some embodiments, in order to reduce the length of the housing connectors 931-939 of the stacked battery modules, the group electrodes of the battery pack can be arranged on different battery seats of the battery pack. Fig.10, group electrode 2101 may be disposed on bottom battery holder 2131 to couple to housing interface 9211, group electrode 2102 may be disposed on top battery holder 2132 to couple to group electrode 2202 disposed on bottom battery holder 2231, and group electrode 2201 may be disposed on top battery holder 2232 to couple to another group electrode disposed on another bottom battery holder of the bottom battery pack in battery module 30. Therefore, the distance between two group electrodes coupled to the same housing connector may be reduced, and the length of the housing connector may be reduced.

[0214] In some embodiments, some battery modules can be stacked on top of each other, and other battery modules can be arranged side by side in a mounting direction parallel to the front plate of the battery module and in a normal direction perpendicular to the front plate of the battery module. Therefore, when the number of battery modules is equal to four, the battery modules can be stacked into a 2×2 cuboid. In some embodiments, the electrical connection can be coupled as an S-shaped connection. For example, two bottom battery packs in different battery modules can be coupled to each other, and then one of the two bottom battery packs can be further coupled to the top battery pack of the one in the battery module.

[0215] Fig.23 A three-dimensional structural diagram showing a portion of components in a battery system according to an embodiment of the present disclosure is shown for displaying Fig. 20 Fluid flow in the battery system shown in FIG.

[0216] In some embodiments, the housing inlet 9221 coupled to the fluid cooling thermal management system may be coupled to an input flow tube 9223 for coupling to a first flow tube 941 coupled to a first fluid inlet of the battery module 20. In some embodiments, a second flow tube 942 may be used to couple a first fluid outlet of the battery module 20 to a second fluid inlet of the battery module 30, a third flow tube 943 may be used to couple a second fluid outlet of the battery module 30 to a third fluid inlet of the battery module 40, and a fourth flow tube 944 may be used to couple a third fluid outlet of the battery module 20 to a fourth fluid inlet of the battery module 50. In some embodiments, the housing outlet 9222 coupled to the fluid cooling thermal management system may be coupled to an output flow tube 9224 for coupling to a fifth flow tube 945 coupled to a fourth fluid outlet of the battery module 50. In some embodiments, referring to Fig. 20, the input flow tube 9223 can be disposed behind the side wall 92, and the output flow tube 9224 can be disposed below the battery modules 20-50. Therefore, each of the fluid inlet and the fluid outlet can be coupled to a fluid cooling thermal management system or another battery module. In other words, the fluid inlet of one battery module can be coupled to a fluid cooling thermal management system or a fluid outlet of another battery module. In some embodiments, the input flow tube 9223, the first flow tube 941, the second flow tube 942, the third flow tube 943, the fourth flow tube 944, and the output flow tube 9224 are a plurality of housing channels for allowing fluid to flow in the system housing 90.

[0217] In some embodiments, the battery modules may be stacked together. In some embodiments, the second flow tube 942 may be used to connect the first fluid outlet of the battery module 20 to the second fluid inlet of the battery module 30 located above the battery module 20, the third flow tube 943 may be used to connect the second fluid outlet of the battery module 30 to the third fluid inlet of the battery module 40 located above the battery module 30, and the fourth flow tube 944 may be used to connect the third fluid outlet of the battery module 40 to the fourth fluid inlet of the battery module 50 located above the battery module 40.

[0218] In some embodiments, some battery modules can be stacked on top of each other, and other battery modules can be arranged side by side along the installation direction parallel to the front plate of the battery module and the normal direction perpendicular to the front plate of the battery module. Therefore, when the number of battery modules is equal to four, the battery modules can be stacked into a 2×2 cuboid. In some embodiments, the fluid flow between different battery modules can flow as an S-shaped channel. For example, the second flow tube 942 can be used to couple the first fluid outlet of the battery module 20 with the second fluid inlet of the battery module 30 located on the right side of the battery module 20, the third flow tube 943 can be used to couple the second fluid outlet of the battery module 30 with the third fluid inlet of the battery module 40 located above the battery module 30, and the fourth flow tube 944 can be used to couple the third fluid outlet of the battery module 40 with the fourth fluid inlet of the battery module 50 located on the left side of the battery module 40.

[0219] In some embodiments, in order to reduce the length of the flow tube for stacking battery modules, the positions of the fluid inlet and the fluid outlet of the battery group in the first layer of the battery system 9 may be different from the fluid inlet and the fluid outlet of the battery group in the second layer of the battery system 9. In some embodiments, the battery group in the second layer of the battery system 9 may be arranged above the battery group in the first layer of the battery system 9. For example, the fluid inlet of the battery group in the first layer of the battery system 9 may be arranged at the lower left corner of a corresponding front plate, and the fluid outlet of the battery group in the first layer of the battery system 9 may be arranged at the upper right corner of the corresponding front plate. In addition, the fluid inlet of the battery group in the second layer of the battery system 9 may be arranged at the lower right corner of a corresponding front plate to face the fluid outlet of the battery group in the first layer of the battery system 9, or to be connected to the fluid outlet of another battery group in the second layer of the battery system 9. Then, the fluid outlet of the battery group in the second layer of the battery system 9 may be arranged at the upper left corner of the corresponding front plate to face the fluid inlet of the battery group in the third layer of the battery system 9, or to be connected to another fluid inlet of another battery group in the third layer of the battery system 9. Therefore, the distance between the fluid inlet and the fluid outlet in different battery modules can be reduced, and the length of the flow tube can be reduced.
