Description

REFERENCE TO A RELATED REGISTRATION

[0001] The present application claims priority over the Chinese patent application filed with the Chinese Patent Office on March 31, 2023, under application number 2023103414099, entitled "Battery Module with Multi-Sided Cooling". The entire content of that application is incorporated into the present application by reference. TECHNICAL AREA

[0002] The present application relates to the field of batteries, in particular to a battery module with multi-sided cooling. STATE OF THE ART

[0003] With the rapid development of the electric vehicle market, battery capacity has steadily increased. To shorten battery charging times and enhance the user-friendliness of electric vehicles, fast-charging solutions have been developed. However, fast charging can generate significant heat and lead to battery overheating. To improve battery performance in terms of rapid heat dissipation, existing technology utilizes the addition of cooling plates for multi-sided cooling of the battery module to increase heat dissipation capacity. Furthermore, a thermally conductive structural adhesive is applied between the heat-dissipating plate and the battery to improve thermal conductivity.

[0004] For batteries with a CTP solution (CTP, i.e., Cell To PACK, is a battery configuration solution where the battery is directly integrated into the battery pack, eliminating the need for an intermediate module architecture, simplifying the pack structure, and improving space utilization), a solution without grouping forces is used to simplify the structure. In this approach, the battery cells are installed directly in the pack using a stacking device, resulting in gaps between the battery cells. When a multi-sided cooling plate is used for heat dissipation, the thermally conductive structural adhesive can easily overflow into the gaps between the battery cells. This overflowing adhesive often presses against the battery cell electrodes, causing safety issues. SUMMARY OF THE INVENTION

[0011] Optionally, the adhesive barriers include soft foam.

[0012] Optionally, the heat exchanger plate includes a lower heat exchanger plate located at the bottom of the battery assembly, and a first heat exchanger plate and a second heat exchanger plate adjacent to the lower heat exchanger plate, arranged on the two sides of the battery assembly, with the first heat exchanger plate and the second heat exchanger plate both perpendicular to the large surfaces of the battery cells.

Those skilled in the art will understand the specific meanings of the terms in this application based on the specific circumstances.

[0022] In addition, the features described below in the various embodiments of the present application may be combined, unless they contradict each other. Designs

[0023] As in the Fig. As shown in 1-5, the battery module with multi-sided cooling according to the present embodiment has: a battery arrangement 4 formed by stacking a plurality of battery cells 41 in a direction perpendicular to large surfaces of the battery cells 41; at least two heat exchanger plates 3, wherein each heat exchanger plate is attached to one of the side surfaces of the battery arrangement 4 and the heat exchanger plates 3 are designed to contain a heat exchange medium; Adhesive barriers 7 are attached between the large surfaces of each pair of adjacent battery cells 41, wherein the adhesive barriers 7 are arranged at least partially around the circumferential edges of the large surfaces of the battery cells 41 and are distributed near the positions of the heat exchanger plates 3, and wherein the adhesive barriers 7 are configured to prevent an adhesive from entering the space between the large surfaces of each pair of adjacent battery cells 41.

[0024] Optionally, the battery cells 41 can be prismatic batteries, where the large surface area of ​​the battery cells 41 is specifically the length-height surface area of ​​the prismatic battery. A large number of battery cells 41 are stacked perpendicular to the large surfaces of the battery cells 41 to form the battery assembly 4. Adhesive barriers 7 are attached between the large surfaces of each pair of adjacent battery cells 41. When the heat exchanger plates 3 are attached to the side faces of the battery assembly 4, the adhesive barriers 7 prevent adhesive from entering the space between the large surfaces of each pair of adjacent battery cells 41, thus preventing adhesive overflow and safety issues arising from adhesive overflowing and pressing against the electrodes of the battery cells 41.

[0025] It should be noted that the positions of the adhesive barriers 7 near the heat exchanger plates 3 refer to the edges, with the adhesive barriers 7 being located on the edges on the side where the heat exchanger plates 3 are arranged when the adhesive barriers 7 are positioned along the circumferential edges of the large surfaces of the battery cells 41. For example, if the heat exchanger plates 3 are positioned on the bottom surface and the left side surface of the battery assembly 4, the adhesive barriers 7 are provided between the large surfaces of each pair of adjacent battery cells 41, specifically along the circumferential edges of the bottom surface and the left side surface of the battery cells 41. This ensures that the positions of the adhesive barriers 7 correspond to the positions of the heat exchanger plates 3, resulting in the effect of a direct adhesive barrier.

[0026] Furthermore, when the battery assembly 4 is clamped and installed in the housing, the adhesive barriers 7 between the battery cells can act as a buffer.

[0027] The multi-sided cooling battery module according to the present application comprises adhesive barriers 7 that are attached between the large surfaces of each pair of adjacent battery cells 41. The adhesive barriers 7 are arranged at least partially around the circumferential edges of the large surfaces of the battery cells 41 and distributed near the positions of the heat exchanger plates 3. This prevents adhesive from entering the space between the large surfaces of each pair of adjacent battery cells 41, thereby preventing adhesive overflow and avoiding safety problems that could arise from adhesive overflowing and pressing against the electrodes of the battery cells 41.

[0028] Furthermore, the adhesive barriers 7 can work together with a variety of heat exchanger plates 3 to prevent the adhesive from entering the space between the large surfaces of any two adjacent battery cells 41, ensuring that no adhesive overflows between the large surfaces of the two adjacent battery cells 41.

[0029] In particular, as in Fig. As shown in Figure 3, the adhesive barriers 7 are constructed in an L-shape, and two adhesive barriers 7 are arranged in pairs and enclose each other to form a square shape.

[0030] Each pair of adhesive barriers 7 is located between the large surfaces of two adjacent battery cells 41 and surrounds each other to form a cavity together with the large surfaces of the battery cells 41.

[0031] The adhesive barriers 7 are designed to prevent the adhesive from entering the cavity.

[0032] Two of the adhesive barriers 7 are arranged in pairs and enclose each other to form a square shape, and together with the large surfaces of the battery cells 41, form a cavity, and the two adhesive barriers 7 are connected end to end. This prevents adhesive from entering through the gap between the two adhesive barriers 7, thus improving the barrier effect against the adhesive.

[0033] The L-shaped adhesive barriers 7 according to the present embodiment are easier to apply and require less labor. Furthermore, when the L-shaped adhesive barriers 7 enclose each other to form a square shape, the breakage rate is lower. The L-shaped adhesive barriers represent the most cost-effective method, offering higher efficiency in terms of bonding and a lower failure rate.

[0034] The L-shaped adhesive barriers 7 according to the present embodiment offer a better barrier effect against the adhesive than a circular frame adhesive barrier method or a method without an adhesive barrier. The circular frame adhesive barrier method can cause excessive stress on the electrodes of battery cells in the end-of-line (EOL) phase (EOL being the functional testing before automotive electronic products are shipped), leading to problems such as lithium precipitation. The method without an adhesive barrier can easily cause adhesive to overflow between battery cells, potentially resulting in the overflowing adhesive pressing against the battery cell electrodes, leading to safety issues.

[0035] In particular, the adhesive barriers 7 consist of an elastic material and the restoring force “F” of the adhesive barriers satisfies the following: F = σ * A, where “σ” is the restoring load corresponding to the compression of the adhesive barriers 7 in the limit state, and “A” is the area of ​​the compressed region of the adhesive barriers 7.

[0036] The restoring force “F” of the adhesive barriers also fulfills: F≤F clamp , where “F clamp “The frictional force is generated by the clamping device when it clamps the stacked battery assembly.

[0037] By ensuring that the restoring force “F” of the adhesive barriers 7 is less than or equal to the frictional force generated by the clamping device when the stacked battery assembly 4 is clamped, the battery assembly 4 can be seamlessly clamped and easily installed in the housing.

[0038] Optionally, the extent of compression of the adhesive barriers 7 in their limit state can be determined based on the thickness tolerance of the adhesive barriers 7, the gap tolerance of the battery cells and the thickness tolerance of the filler between the battery cells, as explained below.

[0039] In particular, the maximum compression rate η meets max The adhesive barriers 7 are as follows: ηmax=1−X−L−A−B−C1−C2−DH where “X” is the gap dimension between adjacent battery cells 41, “L” is the thickness of the additional filler 8 present between adjacent battery cells 41, “A” is the thickness tolerance of the adhesive barriers 7, “B” is the thickness tolerance of the filler 8, “Cl” is the position tolerance of the first battery cell 41 of the adjacent battery cells 41, “C2” is the position tolerance of the second battery cell 41 of the adjacent battery cells 41, “D” is the thickness tolerance of the battery cells 41, and “H” is the original design thickness of the adhesive barriers 7.

[0040] Positional tolerance refers to the total permissible variation in the direction or position of an associated actual element relative to a reference. In the present embodiment, “C1” is the positional tolerance of the first battery cell among the adjacent battery cells, representing the deviation between the first battery cell and its reference position; “C2” is the positional tolerance of the second battery cell among the adjacent battery cells, representing the deviation between the second battery cell and its reference position.

[0041] In a specific embodiment, the gap dimension “X” between adjacent battery cells 41 can be in the range of 4 mm ≤ X ≤ 5 mm, and specifically be 4.1 mm, 4.3 mm, 4.5 mm, or 4.7 mm. In the present embodiment, X = 4.3 mm is optionally used.

[0042] The thickness “L” of the filler material 8 additionally present between adjacent battery cells 41 can be in the range of 2.5 mm ≤ X ≤ 3.5 mm, and specifically 2.8 mm, 3.1 mm, 3.3 mm or 3.5 mm. In the present embodiment, L = 3.1 mm is optionally used.

[0043] The thickness tolerance “A” of the adhesive barriers 7 can be: ±0.1 mm.

[0044] The thickness tolerance “B” of filler 8 can be: ±0.2 mm.

[0045] The positional tolerance “C1” of the first battery cell of the adjacent battery cells 41 can be: ±0.2 mm.

[0046] The positional tolerance “C2” of the second battery cell of the adjacent battery cells 41 can be: ±0.2 mm.

[0047] The thickness tolerance “D” of the battery cells 41 can be: ±0.3 mm.

[0048] The original design thickness “H” of the adhesive barriers 7 can be in the range of 2 mm ≤ H ≤ 3 mm, and specifically 2.2 mm, 2.4 mm, 2.6 mm, or 2.8 mm. In the present embodiment, H = 2.4 mm is used optionally.

[0049] Optionally, the minimum compression rate η is met. min The adhesive barriers 7 are as follows: ηmin=1−X−L+A+B+C1+C2+DH.

[0050] Additionally, during the initial design phase, the initial design thickness of the adhesive barriers 7 can be determined after the material of the adhesive barriers 7 has been specified. The restoring load of the adhesive barriers can be selected by considering both the maximum and minimum compression rates. The maximum restoring load should be less than the frictional force exerted by the device on the side faces of the battery cell, while the minimum restoring load should correspond to the extrusion force of the adhesive on the adhesive barriers, preventing the adhesive barriers from rebounding. For example, in the present embodiment, the restoring load of the adhesive barriers should meet the following conditions: σ ≥ 10 kPa at 10% and σ ≤ 150 kPa at 90%.This means that at a compression rate of 10%, the restoring load of the adhesive barriers is ≥10 kPa, and at a compression rate of 90%, the restoring load of the adhesive barriers is ≤150 kPa. The original design thickness of the adhesive barriers 7 can then be determined by an inverse comparison of the maximum compression rate and the minimum compression rate.

[0051] Additionally, the restoring load of the adhesive barriers can be determined based on the above compression rates, and the restoring force of the adhesive barriers can be determined based on the restoring load.

[0052] Optionally, the adhesive barriers include 7 soft foam. Furthermore, foam with low resilience can be used for the adhesive barriers 7.

[0053] In one variant, the material of the adhesive barriers 7 can be replaced by other foams with a high compression rate and low recovery force, such as melamine foam, highly elastic PU foam and silicone foam, etc.

[0054] Alternatively, the material of filler 8 can be replaced by heat-insulating materials such as ceramic aerogel felt, fiberglass aerogel felt and pre-oxidized silica aerogel felt.

[0055] In particular, as described in the Fig. 2 and Fig. Figure 4 shows the heat exchanger plate 3, a lower heat exchanger plate 33 located at the bottom of the battery assembly 4, and a first heat exchanger plate 31 and a second heat exchanger plate 32 adjacent to the lower heat exchanger plate 33, arranged on the two sides of the battery assembly 4, and the first heat exchanger plate 31 and the second heat exchanger plate 32 are both perpendicular to the large surfaces of the battery cells 41.

[0056] Alternatively, three heat exchanger plates 3 can be provided, such that the heat exchanger plates 3 are attached to the three side faces of the battery assembly 4, which ensures effective cooling of the battery assembly 4. In contrast to the heat dissipation achieved by attaching a water-cooled plate only to the bottom of the battery cell, which makes it difficult to ensure effective heat dissipation during charging and discharging, the present embodiment uses a three-sided heat dissipation method, wherein the water-cooled plates are attached to the bottom face and two side faces of the battery cell. This ensures rapid heat dissipation during charging and discharging of the battery cells.

[0057] In particular, the multi-sided cooling battery module further comprises a heat exchanger hose assembly 5 designed to connect the lower heat exchanger plate 33, the first heat exchanger plate 31 and the second heat exchanger plate 32.

[0058] As in the Fig. 2 and Fig.As shown in Figure 4, the first heat exchanger plate 31 is attached to the left side face of the battery assembly 4 using a thermally conductive structural adhesive. The second heat exchanger plate 32 is attached to the right side face of the battery assembly 4 using a thermally conductive structural adhesive. The first heat exchanger plate 31 and the second heat exchanger plate 32 are connected by the heat exchanger hose assembly 5, which ensures a cooling circuit at the lateral cooling surfaces. In particular, the heat exchanger hose assembly 5 includes a fluid inlet at the bottom and a fluid outlet at the top, which reduces the flow rate to ensure that the battery cell has sufficient time for heat dissipation. The lower heat exchanger plate 33 is attached to the bottom of the battery assembly 4 using a thermally conductive structural adhesive.The liquid inlets and liquid outlets of the lower heat exchanger plate 33 and the side water cooling plate are each connected to a water pump.

[0059] Optionally, the plate substrate 35 of the heat exchanger plate 3 has a profiled structure. Each heat exchanger plate 3 forms two cavities within the plate, and these two cavities are interconnected to allow heat dissipation during overflow. The outer surface of the plate substrate 35 is coated with a sprayed-on layer 36, which provides thermal insulation and corrosion resistance. A support 34 is provided at one end of the plate substrate 35 and is designed to secure and mount the heat exchanger plate 3.

[0060] In particular, the multi-sided cooling battery module further comprises a CCS assembly 2, which is electrically connected to the battery cells 41. The CCS assembly 2 consists of an upper insulating layer, a lower insulating layer, a busbar, a temperature sensor mount, a flexible printed circuit board, a thermally conductive foam, and a temperature sensor. Optionally, the CCS assembly can be replaced by other solutions, such as vacuum forming, injection molding, and hot pressing. The flexible printed circuit board can be replaced by other solutions, such as flexible printed circuit boards (FPCs), flexible direct current (FDCs), and flexible fuses (FFCs). Optionally, the aluminum rods in the CCS assembly 2 are welded to the battery cells 41 of the battery assembly to achieve a conductive connection.

[0061] Additionally, an insulating layer 1 is attached to the CCS assembly 2. This insulating layer 1 provides insulation and protection. It can consist of materials or structures such as ceramic fiber mats, PC boards, and a top cover.

[0062] Additionally, the multi-sided cooling battery module may also include an output terminal guard 6 attached to the end plate or side support of the housing to provide insulation and protection for the output terminals.

[0063] In particular, the multi-sided cooling battery module includes a module without grouping force. Compared to modules that use rollers and end plates for fastening, the module without grouping force uses the stacking device to install the battery cells directly in the pack, which is more cost-effective and can better ensure module consistency.

[0064] It is obvious that the embodiments described above are merely examples for illustrative purposes and are not intended to limit the possible embodiments. Those skilled in the art will recognize that other variants or modifications based on the above description are possible. It is neither necessary nor possible to list all embodiments. Any obvious variants or modifications resulting therefrom fall within the scope of protection of this application.
