Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a battery pack and an electrical device. Background Technology

[0002] The battery pack contains multiple cell groups, each containing multiple cells. For the same cell group, data acquisition and signal transmission are achieved through a CCS (Battery Connection System) module. In related technologies, the CCS module includes an FPC (Flexible Printed Circuit) acquisition board and a busbar. Both the FPC acquisition board and the busbar are located on the same side of the cell group. This can cause the FPC acquisition board to easily block the explosion-proof valve in the cell, resulting in poor gas discharge after the explosion-proof valve opens, thus affecting the safety performance of the battery pack. Utility Model Content

[0003] To address the aforementioned technical problems, embodiments of this application provide a battery pack and electrical equipment that can improve the problem of the acquisition board easily obstructing the explosion-proof valve and enhance the safety performance of the battery pack.

[0004] In a first aspect, a battery pack is provided, comprising:

[0005] Box;

[0006] A battery cell assembly is disposed inside the enclosure. The battery cell assembly includes a first side and a second side, the first side and the second side are not coplanar, and the first side is provided with an explosion-proof valve.

[0007] The bracket includes a mounting frame and a mounting plate. The mounting frame is located on the first side and is offset from the explosion-proof valve. The mounting plate is connected to the side of the mounting frame away from the explosion-proof valve and is bent relative to the mounting frame to cover the second side.

[0008] Multiple busbars are disposed within the mounting frame, and the multiple busbars are connected to the first side;

[0009] A data acquisition board is disposed on the side of the mounting plate opposite to the second side, and the data acquisition board is electrically connected to multiple busbars.

[0010] According to a first aspect of this application, the battery pack includes a plurality of battery cells distributed along a first direction, and the mounting plate and the acquisition plate both extend along the first direction to cover the plurality of battery cells.

[0011] According to a first aspect of this application, the acquisition board includes a first end and a second end disposed opposite to each other along the first direction;

[0012] The battery pack also includes:

[0013] A low-voltage plug-in is electrically connected to the acquisition board, and the low-voltage plug-in is located between the first end and the second end.

[0014] According to a first aspect of this application, the housing is provided with an installation beam;

[0015] The low-voltage plug-in includes:

[0016] The support plate is connected to the mounting beam;

[0017] The plug-in body is mounted on the support plate and is electrically connected to the acquisition board.

[0018] According to a first aspect of this application, the low-voltage plug-in further includes:

[0019] The first connecting plate is connected to the acquisition plate;

[0020] The second connecting plate connects the first connecting plate and the plug body. The second connecting plate is bent relative to the first connecting plate and is located on the side of the busbar away from the first side.

[0021] The first connecting plate has an insulating protective layer on the side near the busbar and the second connecting plate has an insulating protective layer on the side near the busbar.

[0022] According to a first aspect of this application, mounting brackets are provided on opposite sides of the mounting beam, the support plate abuts against the mounting beam, and the support plate is connected to the mounting brackets.

[0023] According to a first aspect of this application, the mounting frame is provided with a plurality of separators, and the separators are provided between any two adjacent busbars.

[0024] According to a first aspect of this application, the mounting frame is provided with a protrusion, the busbar is provided with a mounting hole, and the protrusion is embedded in the mounting hole.

[0025] According to a first aspect of this application, the battery pack further includes:

[0026] Electrical connectors connect the acquisition board and the busbar;

[0027] A voltage acquisition device is mounted on the electrical connector.

[0028] A temperature acquisition element is mounted on the electrical connector.

[0029] Secondly, an electrical appliance is also provided, including:

[0030] The battery pack as described in the previous embodiment.

[0031] The battery pack and electrical equipment provided in this application have the following advantages: First, they utilize a bracket as a mounting carrier for the data acquisition board, which avoids direct contact between the data acquisition board and the battery cell assembly. Second, the bracket includes a mounting plate and a mounting frame. By offsetting the mounting frame from the explosion-proof valve, the mounting frame can prevent the explosion-proof valve from being obstructed. Third, by bending the mounting plate relative to the mounting frame and connecting the mounting plate to the side of the mounting frame away from the explosion-proof valve, the mounting plate and the explosion-proof valve can be located on different sides (the mounting plate is on the second side, and the explosion-proof valve is on the first side). This ensures that the data acquisition board and the explosion-proof valve are on different sides (the data acquisition board is on the second side, and the explosion-proof valve is on the first side). This effectively improves the problem of the data acquisition board easily obstructing the explosion-proof valve in related technologies, ensures the venting efficiency of the explosion-proof valve, and improves the safety performance of the battery pack.

Detailed Implementation

[0042] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0043] Figure 1 A schematic diagram of the structure of a battery pack provided in an exemplary embodiment of this application from a first-view perspective. Figure 2 This is a schematic diagram of the structure of a battery pack provided in a second view, as an exemplary embodiment of this application. Figure 1 and Figure 2 As shown, the battery pack 100 provided in this application embodiment may include a housing 110 and a cell assembly 120. The cell assembly 120 is disposed inside the housing 110, and the housing 110 can protect the cell assembly 120.

[0044] Figure 3 This is a schematic diagram of the structure of the battery pack, bracket, busbar, and acquisition board provided for an exemplary embodiment of this application. Figure 3 As shown, the battery cell assembly 120 may include a first side 121 and a second side 122. The first side 121 and the second side 122 are not coplanar and do not belong to the same side of the battery cell assembly 120.

[0045] It should be noted that the battery cell assembly 120 typically includes multiple battery cells 124, each with a cover plate and an explosion-proof valve 123. Specifically, the side of the multiple cover plates furthest from the battery cells 124 can form the aforementioned first side 121, that is, the explosion-proof valve 123 is provided on the first side 121.

[0046] In practical applications, the cover plate protects the battery cell 124. The terminals on the cover plate are electrically connected to the tabs on the battery cell 124, enabling current input or output. Correspondingly, the second side 122 is usually the non-cover plate side.

[0047] like Figure 3 As shown, in practical applications, when an abnormal situation occurs in the circuit (such as short circuit, overcharge, over-discharge, etc.), a large amount of gas will be generated inside the battery cell 124. When the gas pressure inside the battery cell 124 reaches the preset threshold, the explosion-proof valve 123 opens to release the gas, thereby preventing the gas pressure inside the battery cell 124 from becoming too high and causing safety accidents such as combustion or explosion.

[0048] It should be noted that each battery cell 124 has a cover plate, and each cover plate has an explosion-proof valve 123. That is, multiple explosion-proof valves 123 are correspondingly provided on the first side 121. The multiple explosion-proof valves 123 are positioned in the same position on the corresponding cover plate, and the multiple explosion-proof valves 123 are arranged along the first direction (reference). Figure 3 They are distributed along the X-axis and are located on the same straight line.

[0049] It should be understood that if the explosion-proof valve 123 is obstructed by other components, its venting efficiency in the open state will be affected. Therefore, to ensure the venting efficiency of the explosion-proof valve 123, obstruction by other components should be avoided. This will be explained in detail below.

[0050] like Figure 3 As shown, the battery pack 100 may also include a bracket 130, which may include a mounting frame 131. The mounting frame 131 is located on the first side 121 and is offset from the explosion-proof valve 123. This avoids the mounting frame 131 from obstructing the explosion-proof valve 123.

[0051] It should be noted that when multiple explosion-proof valves 123 are distributed along the same straight line in the first direction, the misalignment of the mounting frame 131 and the explosion-proof valves 123 can be understood as the mounting frame 131 being completely misaligned with the multiple explosion-proof valves 123, that is, the straight line where the mounting frame 131 and the multiple explosion-proof valves 123 are located has no coincidence point.

[0052] like Figure 3 As shown, the battery pack 100 may also include multiple busbars 140, which are disposed within the mounting frame 131. The mounting frame 131 can limit the multiple busbars 140 (which will be described in detail later), making it convenient for the multiple busbars 140 to be installed and fixed.

[0053] It should be noted that multiple busbars 140 are connected to the first side 121, and multiple busbars 140 can electrically connect multiple battery cells 124 to realize the series and parallel connection of multiple battery cells 124.

[0054] like Figure 3As shown, the battery pack 100 may also include a data acquisition board 150, which is electrically connected to multiple busbars 140. The data acquisition board 150 can collect parameters such as voltage and temperature of multiple cells 124 in real time through the multiple busbars 140.

[0055] like Figure 3 As shown, the aforementioned bracket 130 may also include a mounting plate 132. The mounting plate 132 is bent relative to the mounting frame 131. The mounting plate 132 is connected to the side of the mounting frame 131 away from the explosion-proof valve 123. In this way, the mounting plate 132 covers the second side 122, that is, the mounting plate 132 and the explosion-proof valve 123 are located on different sides (the mounting plate 132 is located on the second side 122, and the explosion-proof valve 123 is located on the first side 121), which can prevent the mounting plate 132 from obstructing the explosion-proof valve 123.

[0056] It should be noted that the aforementioned data acquisition plate 150 is located on the side of the mounting plate 132 facing away from the second side 122. In this way, firstly, the mounting plate 132 can separate the data acquisition plate 150 from the second side 122, preventing the data acquisition plate 150 from directly contacting the second side 122 and preventing short circuit accidents (the mounting plate 132 is made of insulating material); secondly, the data acquisition plate 150 can be moved to cover the second side 122, preventing the data acquisition plate 150 from being on the same side as the explosion-proof valve 123 (the data acquisition plate 150 is located on the second side 122, and the explosion-proof valve 123 is located on the first side 121). This effectively improves the problem in related technologies where the data acquisition plate 150 easily obstructs the explosion-proof valve 123, ensuring the venting efficiency of the explosion-proof valve 123 and improving the safety performance of the battery pack 100.

[0057] In one embodiment, the acquisition plate 150 and the mounting plate 132 can be relatively fixed by means of bonding, welding or other methods.

[0058] In one embodiment, the bracket 130 is a plastic frame, which can serve as insulation and also provide support for the acquisition board 150 and the busbar 140.

[0059] like Figure 2 and Figure 3 As shown, the battery cell assembly 120 may include multiple battery cells 124. The multiple battery cells 124 are connected in series and / or in parallel to form a module with specific voltage and capacity parameters, which is the battery cell assembly 120.

[0060] It should be noted that the number of cells 124 included in each cell group 120 may be the same or different.

[0061] It should be understood that the number of cells 124 included in each cell group 120 can be set according to actual conditions, and this application embodiment does not make a specific limitation on this.

[0062] like Figure 3As shown, multiple battery cells 124 are arranged along a first direction (reference). Figure 3 The mounting plate 132 and the acquisition plate 150 are distributed along the X-axis direction, and both extend along the first direction. That is to say, the extension direction of the mounting plate 132 and the acquisition plate 150 is the same as the distribution direction of the multiple battery cells 124, which makes it convenient for the acquisition plate 150 to acquire the parameters of the multiple battery cells 124.

[0063] In practical applications, when the number of cells 124 in the cell group 120 increases, the length of the mounting plate 132 and the acquisition plate 150 along the first direction can be extended accordingly when producing the mounting plate 132 and the acquisition plate 150. In this way, when the number of cells 124 increases, the scheme of splicing multiple acquisition plates 150 together can be avoided, thereby effectively reducing the number of acquisition plates 150 used, reducing the consumption of acquisition plates 150, and reducing manufacturing costs.

[0064] It should be understood that the length of the mounting plate 132 along the first direction is greater than the length of the acquisition plate 150 along the first direction. In this way, the projection of the acquisition plate 150 on the mounting plate 132 is completely within the outline of the mounting plate 132. The mounting plate 132 can effectively prevent the acquisition plate 150 from directly contacting the battery cell 124, avoid short circuit accidents, and improve the safety performance of the battery pack 100.

[0065] Figure 4 This is a schematic diagram of the structure of the bracket, busbar, acquisition board, and low-voltage plug-in provided for an exemplary embodiment of this application. Figure 3 and Figure 4 As shown, the mounting frame 131 is provided with multiple separators 133, and a separator 133 is provided between any two adjacent busbars 140. It should be understood that the separators 133 can prevent two adjacent busbars 140 from directly contacting each other, thus avoiding short circuit accidents and improving the overall safety performance of the battery pack 100.

[0066] In one embodiment, the separator 133 is connected to the mounting frame 131, and the mounting frame 131 serves as the carrier of the separator 133. The separator 133 and the mounting frame 131 form an integral whole, which facilitates the one-time installation of the separator 133 and the mounting frame 131 and improves installation efficiency.

[0067] like Figure 3 and Figure 4 As shown, the mounting frame 131 has a protrusion 134, and the busbar 140 has a mounting hole 141, with the protrusion 134 embedded in the mounting hole 141. It should be understood that during the installation of the busbar 140, the protrusion 134 can serve as a positioning element, facilitating quick confirmation of the busbar 140's installation position. This improves both the installation efficiency and accuracy of the busbar 140.

[0068] In one embodiment, after the protrusion 134 is embedded in the mounting hole 141 of the busbar 140, the protrusion 134 and the busbar 140 can be fixed relative to each other by heat fusion. This can improve the connection stability between the busbar 140 and the protrusion 134 and prevent the busbar 140 from shaking or falling off.

[0069] In one embodiment, the protrusion 134 is connected to the mounting frame 131, which serves as the carrier of the protrusion 134. The separator 133 forms an integral part with the protrusion 134, facilitating the one-time installation of the protrusion 134 and the mounting frame 131 and improving installation efficiency.

[0070] like Figure 4 As shown, the battery pack 100 may also include an electrical connector 170, which connects the acquisition board 150 and the bus 140. The acquisition board 150 and the bus 140 can transmit signals through the electrical connector 170.

[0071] like Figure 4 As shown, the acquisition board 150 and the busbar 140 are located on different sides of the battery pack 120 (the acquisition board 150 is located on the second side 122, and the busbar 140 is located on the first side 121). Therefore, the electrical connector 170 is L-shaped, with one end connected to the acquisition board 150 and the other end connected to the busbar 140, adapting to the installation positions of the acquisition board 150 and the busbar 140 for easy connection.

[0072] Figure 5 This is a schematic diagram of the structure of the bracket, acquisition board, and low-voltage plug-in provided for an exemplary embodiment of this application. Figure 4 and Figure 5 As shown, the battery pack 100 may also include a low-voltage plug-in 160, which is electrically connected to the acquisition board 150. The low-voltage plug-in 160 can be used to connect to an external battery management system, so that the battery management system can obtain relevant parameters collected by the acquisition board 150.

[0073] like Figure 4 and Figure 5 As shown, the acquisition board 150 includes components along the first direction (reference). Figure 4 and Figure 5The low-voltage plug 160 is located between the first end 151 and the second end 152, which are positioned relative to each other along the X-axis direction. During the insertion of the low-voltage plug 160, the wire harness can extend from the low-voltage plug 160 toward the first end 151 and the second end 152 respectively. Therefore, the wire harness will not be concentrated at the first end 151 or the second end 152. This can improve the problem of easy interference between wire harnesses and increase the flexibility of cable arrangement, making full use of the internal space of the battery pack 100 and improving the space utilization rate of the battery pack 100.

[0074] In one embodiment, the distance between the low-voltage plug 160 and the first end 151 along the first direction may be smaller than the distance between the low-voltage plug 160 and the second end 152 along the first direction.

[0075] In one embodiment, the distance between the low-voltage plug 160 and the first end 151 along the first direction may be greater than the distance between the low-voltage plug 160 and the second end 152 along the first direction.

[0076] In one embodiment, the distance between the low-voltage plug 160 and the first end 151 along the first direction may be equal to the distance between the low-voltage plug 160 and the second end 152 along the first direction.

[0077] like Figure 4 As shown, the battery pack 100 may also include a voltage acquisition unit 180, which is disposed on the electrical connector and can be used to acquire the operating voltage of the cell assembly 120.

[0078] like Figure 4 As shown, the battery pack 100 may also include a temperature acquisition element 190, which is disposed on the electrical connector and can be used to acquire the operating temperature of the cell assembly 120.

[0079] In practical applications, the acquisition board 150 acquires the operating voltage and operating temperature of the cell pack 120 through the voltage acquisition device 180 and the temperature acquisition device 190, and then transmits them to the battery management system through the low-voltage plug-in 160. The battery management system can adjust the control strategy according to the operating voltage and operating temperature.

[0080] Figure 6 A schematic diagram of the structure of a battery pack provided for another exemplary embodiment of this application. Figure 7 for Figure 6 An enlarged view of point A in the middle. (See diagram below.) Figure 6 and Figure 7As shown, the housing 110 contains a mounting beam 111; correspondingly, the low-voltage plug-in 160 may include a support plate 161 and a plug-in body 162. The support plate 161 is connected to the mounting beam 111, and the plug-in body 162 is mounted on the support plate 161. The support plate 161 serves as a carrier to support the plug-in body 162, thereby increasing the structural strength of the plug-in body 162 and protecting it. The plug-in body 162 is electrically connected to the acquisition board 150 and can be used to connect to the battery management system mentioned earlier.

[0081] It should be noted that the connection between the support plate 161 and the mounting beam 111 allows the plug body 162 to be relatively fixed relative to the mounting beam 111. In this way, the plug body 162 is less prone to deformation during the insertion of electrical components into the plug body 162. This facilitates quick insertion of electrical components into the plug body 162, improves insertion efficiency, and also protects the plug body 162.

[0082] In one embodiment, the mounting beam 111 can be a crossbeam inside the box 110; or, the mounting beam 111 can also be a longitudinal beam inside the box 110.

[0083] In one embodiment, the support plate 161 can be made of a material with good insulation properties, such as epoxy or PC (polycarbonate). In this way, the support plate 161 can provide load-bearing and protection for the plug-in body 162, and also play a good insulating role, so as to avoid direct electrical connection between the plug-in body 162 and the mounting beam 111 and prevent short circuit accidents.

[0084] like Figure 6 and Figure 7 As shown, mounting brackets 112 are provided on opposite sides of the mounting beam 111, and support plate 161 abuts against the mounting beam 111. The mounting beam 111 is used to support the support plate 161 and the plug-in body 162. The support plate 161 is connected to the mounting brackets 112, which can fix the plug-in body 162 relative to the mounting beam 111.

[0085] It should be noted that mounting brackets 112 are added to both sides of the mounting beam 111. Both mounting brackets 112 are connected to the support plate 161, which can improve the installation stability of the support plate 161, thereby improving the installation stability of the plug-in body 162 and avoiding deformation and shaking of the plug-in body 162 during the insertion process.

[0086] In one embodiment, the connection between the support plate 161 and the mounting bracket 112 may include welding, bonding, detachable connection, etc.

[0087] like Figure 7As shown, in one embodiment, the mounting bracket 112 is L-shaped. One end of the mounting bracket 112 is welded to the mounting beam 111, and the other end of the mounting bracket 112 is provided with a first hole (not shown in the figure). The support plate 161 is provided with a second hole 1321. Fasteners (such as bolts, studs, etc.) pass through the first hole (not shown in the figure) and the second hole 1321. In this way, the mounting bracket 112 and the support plate 161 can be fixed relative to each other, thereby fixing the plug-in body 162 relative to the mounting beam 111.

[0088] Figure 8 This is a schematic diagram of the structure of a low-voltage plug-in, acquisition board, and bus provided for an exemplary embodiment of this application. Figure 8 As shown, the low-voltage plug-in 160 may also include a first connecting plate 163 and a second connecting plate 164. The first connecting plate 163 is connected to the acquisition plate 150, and the second connecting plate 164 connects the first connecting plate 163 and the plug-in body 162. The acquisition plate 150 and the plug-in body 162 can transmit signals through the first connecting plate 163 and the second connecting plate 164.

[0089] like Figure 7 and Figure 8 As shown, the second connecting plate 164 is bent relative to the first connecting plate 163, allowing the second connecting plate 164 to be positioned on the side of the busbar 140 away from the first side 121. In other words, the support plate 161 and the plug-in body 162 are located on the side of the busbar 140 away from the first side 121, and the second connecting plate 164 can guide the support plate 161 and the plug-in body 162 to the top of the mounting beam 111, facilitating the connection between the support plate 161 and the mounting beam 111.

[0090] like Figure 8 As shown, the first connecting plate 163 and the second connecting plate 164 are both provided with an insulating protective layer 165 on the side of the first connecting plate 163 near the busbar 140 and the side of the second connecting plate 164 near the busbar 140. The insulating protective layer 165 can prevent the first connecting plate 163 from directly contacting the busbar 140 and can also prevent the second connecting plate 164 from directly contacting the busbar 140. In this way, short circuit accidents can be effectively avoided and the safety performance of the battery pack 100 can be improved.

[0091] In one embodiment, the insulating protective layer 165 is made of foam, which not only provides the aforementioned insulation but also acts as a buffer. That is, the foam can reduce the pressure between the first connecting plate 163 and the busbar 140, as well as the pressure between the second connecting plate 164 and the busbar 140, thus protecting the first connecting plate 163, the second connecting plate 164, and the busbar 140.

[0092] This application embodiment also provides an electrical device that may include the battery pack 100 as described in the previous embodiment and has all the functions of the battery pack 100.

[0093] It should be understood that the beneficial effects of this electrical equipment can be compared with the beneficial effects of the aforementioned battery pack 100.

[0094] In one embodiment, the electrical equipment may include automobiles, construction machinery, special equipment, etc.

Furthermore, the specific details disclosed above are for illustrative and facilitative purposes only, and are not limitations.
