[0045] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0046] The temperature regulating component 20 according to an embodiment of the present invention will be described below with reference to the accompanying drawings. The temperature regulating component 20 can be used to regulate the temperature of the battery cell 11 .

[0047] Reference Figure 1-Figure 2 According to the temperature regulating component 20 of the first embodiment of the utility model, the temperature regulating component 20 includes a heat conducting plate 21 and a heating film 30. The heating film 30 is provided on both sides of the heat conducting plate 21 in the thickness direction. The heating film 30 is used to heat the battery cell 11.

[0048] The heating film 30 of the temperature regulating component 20 can heat the battery cell 11. The temperature regulating component 20 can regulate the temperature of the battery cell 11, so that the battery cell 11 can work within its normal temperature range, which can improve the working efficiency and service life of the battery cell 11 to a certain extent.

[0049] Since heating films 30 are provided on both sides of the heat conducting plate 21 in the thickness direction, the temperature regulating component 20 can have a larger heating area, and both sides of the temperature regulating component 20 can heat the battery cell 11, so that the temperature regulating component 20 has a higher heating efficiency.

[0050] In addition, by setting the heating film 30 on the heat conducting plate 21, since the heat conducting plate 21 has good thermal conductivity, the heat of the heating film 30 can be dispersed by heat conduction through the heat conducting effect of the heat conducting plate 21, and the phenomenon of local over-temperature caused by local concentration of heat on the temperature regulating component 20 can be improved to a certain extent. Among them, the heat conducting plate 21 can be a metal plate, for example, the heat conducting plate 21 can be an aluminum plate, a copper plate, etc. The heat conducting plate 21 can be a heat spreader, which can better avoid the phenomenon of local over-temperature caused by local concentration of heat on the temperature regulating component 20.

[0051] According to the temperature regulating component 20 of the embodiment of the utility model, the temperature regulating component 2 includes a heat conducting plate 21 and a heating film 30. The heating film 30 is used to heat the battery cell 11, and the heating film 30 is provided on both sides of the heat conducting plate 21 in the thickness direction, which can increase the heating area of ​​the temperature regulating component 20, so that the heating efficiency of the temperature regulating component 20 is higher, thereby improving the heating efficiency of the battery cell 11.

[0052] Reference Figure 1-Figure 2 According to some embodiments of the present invention, the heating film 30 includes a heating area 36, ​​and the heating area 36 is used to heat the battery cell 11. The projection of the heating area 36 on the reference plane is the first projection, and the projection of the heat conducting plate 21 on the reference plane is the second projection, and the first projection is located within the second projection. In this way, the heating area 36 can be entirely covered on the heat conducting plate 21, so that the heat generated by the heating area 36 can be transferred to the heat conducting plate 21, so that the heat generated by the heating area 36 can be fully utilized and can be dispersed on the heat conducting plate 21 by heat conduction.

[0053] According to some embodiments of the present invention, the area ratio of the first projection to the second projection is 40% to 60%, for example, the area ratio of the first projection to the second projection may be 40%, 45%, 50%, 55%, 60%, etc., and the reference plane is a plane perpendicular to the thickness direction of the heat conducting plate 21. If the area ratio of the first projection to the second projection is less than 40%, the area of ​​the heating zone 36 will be smaller, resulting in a poor heating effect of the temperature regulating component 20; if the area ratio of the first projection to the second projection is greater than 60%, the area of ​​the heating zone 36 will be larger, resulting in a higher production cost of the heating zone 36.

[0054] By setting the area ratio of the first projection to the second projection to 40% to 60%, the area of ​​the heating zone 36 of the heating film 30 is moderate, so that the temperature adjustment component 20 has a higher heating efficiency and a lower production cost.

[0055] Reference Figure 1-Figure 2 According to some embodiments of the utility model, the portion of the heat conducting plate 21 located on the outer peripheral side of the heating zone 36 is the connection zone 22. The connection zone 22 is provided with a glue layer 35, and the glue layer 35 is used to connect with the battery cell 11, and the temperature adjustment component 20 is connected with the battery cell 11 through the glue layer 35. By providing the glue layer 35 in the connection zone 22, the temperature adjustment component 20 can be connected with the battery cell 11 through the glue layer 35. The connection zone 22 is located on the outer peripheral side of the heating zone 36, so that the connection zone 22 has a larger connection area, which can make the temperature adjustment component 20 and the battery cell 11 connected more firmly. At the same time, since both sides of the temperature adjustment component 20 are provided with heat-conducting glue layers 35 and are connected to two adjacent rows of battery cells 10, a larger glue area can be provided between the temperature adjustment component 20 and the battery cell 11, further improving the overall structural stability of the battery assembly 100.

[0056] Optionally, the adhesive layer 35 may be a heat-conductive adhesive layer, so that the adhesive layer 35 has a higher thermal conductivity, and can ensure the heat transfer effect between the temperature adjustment component 20 and the battery core 11 .

[0057] Reference Figure 2 as well as Figure 3-Figure 4 According to some embodiments of the present invention, the projection of the heat conducting plate 21 on the reference plane is the second projection, the projection of the connection area 22 on the reference plane is the third projection, the area ratio of the third projection to the second projection is 40% to 60%, for example, the area ratio of the third projection to the second projection can be 40%, 45%, 50%, 55%, 60%, etc., and the reference plane is a plane perpendicular to the thickness direction of the heat conducting plate 21. If the area ratio of the third projection to the second projection is less than 40%, the area of ​​the connection area 22 will be small, resulting in poor stability of the connection between the temperature regulating component 20 and the battery cell 11; if the area ratio of the third projection to the second projection is greater than 60%, the area of ​​the connection area 22 will be large, and accordingly, the area of ​​the heating area 36 will be small, resulting in low heating efficiency of the temperature regulating component 20.

[0058] By setting the area ratio of the third projection to the second projection to 40% to 60%, the area of ​​the heating zone 36 is moderate, thereby ensuring that the temperature adjustment component 20 is more firmly connected to the battery cell 11 and that the temperature adjustment component 20 has a higher heating efficiency.

[0063] The insulating thermally conductive film 31 has a backing layer on the side facing the heat conducting plate 21, and the backing layer on the side facing the heat conducting plate 21 of the first film area 32 of the insulating thermally conductive film 31 can connect the heating structure 33 to the insulating thermally conductive film 31. The backing layer on the side facing the heat conducting plate 21 of the second film area 34 of the insulating thermally conductive film 31 can fix the insulating thermally conductive film 31 and the heating structure 33 to the heat conducting plate 21, and the second film area 34 surrounds the outer peripheral side of the first film area 32, so that the heating film 30 and the heat conducting plate 21 have a larger connection area, thereby making the connection between the heating film 30 and the heat conducting plate 21 more stable.

[0064] In some embodiments of the utility model, the portion of the heat conducting plate 21 located on the outer peripheral side of the heating area 36 is the connection area 22, and the connection area 22 is provided with a glue layer 35, and the temperature regulating component 20 is connected to the battery cell 11 through the glue layer 35.

[0065] Reference Figure 1-Figure 2 According to some embodiments of the utility model, convex areas 25 and concave areas 23 are formed on both sides of the heat conducting plate 21 in the thickness direction, and the convex areas 25 and concave areas 23 on the same side in the thickness direction of the heat conducting plate 21 are alternately arranged in the second direction, and the concave areas 23 are used to connect or contact with the battery cells 11, and the convex areas 25 are opposite to the gaps 13 between two adjacent battery cells 11. Among them, the shape of the heating film 30 can be adapted to the shape of the heat conducting plate 21, the shape of the concave area 23 can be adapted to the shape of the battery cell 11, and part of the battery cell 11 is accommodated in the concave area 23. The battery cells 11 of the two rows of battery cell rows 10 on both sides in the thickness direction of the heat conducting plate 21 can be connected to the concave areas 23, and the heating films 30 are provided on both sides in the thickness direction of the heat conducting plate 21, so that the temperature adjustment component 20 has a higher heating efficiency. In addition, the battery cell 11 is connected to the recessed area 23. For example, the heating film 30 is adapted to the shape of the heat conducting plate 21.

The space can be fully utilized, making the overall structure of the battery assembly 100 more compact.

[0066] According to some embodiments of the present invention, the heating power of the convex area 25 is lower than the heating power of the concave area 23. By making the heating power of the concave area 23 connected to or in contact with the battery cell 11 larger than the heating power of the convex area 25, the large amount of heat generated by the concave area 23 can be quickly transferred to the battery cell 11, thereby improving the heating efficiency of the battery cell 11; and the heating power of the convex area 25 is relatively low. Since the convex area 25 is not connected to or in contact with the battery cell 11, the energy consumption can be reduced while improving the heating efficiency.

[0067] Reference Figure 1 as well as Figure 5 According to some embodiments of the utility model, the heating film 30 includes a heating area 36, ​​and the heating area 36 is used to heat the battery cell 11. The heating area 36 includes a plurality of sub-heating areas 37 arranged along the extension direction of the heat conducting plate 21. At least some of the sub-heating areas 37 have different power densities, which may be different for some of the sub-heating areas 37, or different for all of the sub-heating areas 37. By setting the heating area 36 to include sub-heating areas 37 with different power densities, the sub-heating areas 37 with different power densities in the heating area 36 can be heated according to the requirements with the battery cells 11 having different heating requirements, thereby saving energy and reducing energy consumption while meeting the requirements of the battery cells 11 having different heating requirements.

[0068] For example, the heat dissipation speeds of the battery cells 11 at different positions in the battery cell row 10 are different. For example, the heat dissipation speed of the battery cells 11 at both ends of the battery cell row 10 is relatively high, and the heat dissipation speed of the battery cells 11 at the middle of the battery cell row 10 is relatively low. By arranging a plurality of sub-heating zones 37 along the second direction of the heating zone 36, and at least some of the sub-heating zones 37 have different power densities, the heat dissipation speeds of the battery cells 11 at different positions can be balanced, so that the battery cells 11 in the battery cell row 10 form a relatively uniform temperature rise speed, so that the heating zone 36 can heat the battery cells 11 of the battery cell row 10 more evenly.

[0069] In addition, by providing a plurality of sub-heating zones 37, when the heating zone 36 is partially damaged or fails, it is convenient to replace and repair the heating zone 36, thereby reducing the maintenance cost. For example, when the heating zone 36 is partially damaged or fails, only the sub-heating zone 37 corresponding to the damaged or failed portion can be replaced, without replacing or repairing the entire heating zone 36.

[0070] Reference Figure 1 as well as Figure 5According to some embodiments of the present invention, the heating film 30 includes a heating structure 33 and an insulating heat-conductive film 31, the heating structure 33 is connected to the side of the insulating heat-conductive film 31 facing the heat-conducting plate 21, and the heating structure 33 and at least part of the insulating heat-conductive film 31 form a heating area 37. The heating film 30 includes a heating structure 33 and an insulating heat-conductive film 31, and the heating film 30 can be connected to the heat-conducting plate 21 through a backing adhesive layer. At the same time, the heating structure 33 connected to the side of the insulating heat-conductive film 31 facing the heat-conducting plate 21 can be fixed to the heat-conducting plate 21, and the assembly is relatively simple, and the connection is relatively stable.

[0071] The heating structure 33 includes a plurality of sub-heating structures, which are sequentially arranged in series or in parallel, and the number of the sub-heating structures is the same as the number of the sub-heating zones 37 and corresponds to each other. The plurality of sub-heating structures are sequentially arranged in series or in parallel, and the connection method is relatively simple, and the heating zone 36 can be conveniently divided into a plurality of sub-heating zones 37 with different power densities.

[0072] For example, the heating structure 33 is a heating wire, and the resistance of the heating wire can be adjusted by adjusting the cross-sectional area of ​​the heating wire, so that different sub-heating areas 37 corresponding to different heating wires have different power densities. If multiple heating wires are arranged in series, the larger the cross-sectional area of ​​the heating wire, the smaller the resistance of the heating wire, and the smaller the power density of the heating area 36 corresponding to the heating wire; if multiple heating wires are arranged in parallel, the larger the cross-sectional area of ​​the heating wire, the smaller the resistance of the heating wire, and the larger the power density of the heating area 36 corresponding to the heating wire.

[0073] Reference Figure 1-Figure 2 According to some embodiments of the present invention, the heat conducting plate 21 is a heat spreader. The heat spreader has good thermal conductivity and a relatively uniform heat flux, and can transfer and balance the heat of the heating film 30, so that the heating effect of the temperature adjustment component 20 is relatively uniform. For example, when there is an area of ​​the heating film 30 that is not thermally connected or in thermal contact with the battery cell 11, the heat generated by the heating film 30 in this area will be transferred to the corresponding area of ​​the heating film 30 that is thermally connected or in thermal contact with the battery cell 11 through the heat conducting plate 21, thereby avoiding dry burning of the heating film 30 and improving the heating efficiency and heating effect of the temperature adjustment component 20.

[0074] Reference Figure 3-Figure 4 According to some embodiments of the present invention, a heat exchange channel 24 for the flow of heat exchange medium is formed in the heat conduction plate 21. The heat exchange medium in the heat exchange channel 24 in the heat conduction plate 21, such as a refrigerant, can exchange heat with the battery cell 11 through the heat conduction plate 21, thereby realizing the temperature regulation function of the temperature regulation component 20, such as the heat dissipation function.

[0075] When the temperature of the battery cell 11 in the battery assembly 100 is low and needs to be heated, the heating area 36 of the heating film 30 is thermally connected or in thermal contact with the battery cell 11 and directly heats the battery cell 11, which can realize the heating function of the temperature adjustment component 20. At this time, there is no flow of heat exchange medium in the heat exchange channel 24 in the heat conducting plate 21; when the temperature of the battery cell 11 in the battery assembly 100 is high and needs to be dissipated, the heat exchange medium flows through the heat exchange channel 24 of the heat conducting plate 21 and exchanges heat with the battery cell 11, which can realize the heat dissipation function of the temperature adjustment component 20. At this time, the heating film 30 does not work. The temperature adjustment component 20 can both heat the battery cell 11 and dissipate heat from the battery cell 11, thereby ensuring that the battery cell 11 works within its normal temperature range and improving the working efficiency and service life of the battery cell 11.

[0076] The battery assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. In the embodiment of the present invention, the battery assembly 100 may include a battery module or a battery pack.

[0077] Reference Figure 1-Figure 2 According to the battery assembly 100 of the second embodiment of the utility model, the battery assembly 100 includes multiple rows of battery cell rows 10, which are arranged along a first direction (refer to the e1 direction of the accompanying drawings), and each row of battery cell rows 10 includes multiple battery cells 11 arranged along a second direction (refer to the e2 direction of the accompanying drawings), and the second direction intersects with the first direction, for example, the second direction is perpendicular to the first direction. Multiple battery cells 11 are arranged along the second direction to form battery cell rows 10, and multiple battery cell rows 10 are arranged along the first direction, so that the multiple battery cell rows 10 are arranged more compactly, which is conducive to improving the energy density of the battery pack. Among them, the first direction can be consistent with the thickness direction of the heat conducting plate 21, and the second direction can be consistent with the extension direction of the heat conducting plate 21.

[0078] It should be noted that the “plurality” in the present invention refers to two or more than two.

[0079] The battery assembly 100 also includes a temperature regulating component 20, which may be a temperature regulating component 20 according to the first aspect embodiment described above. A temperature regulating component 20 is provided between two adjacent battery cell rows 10, and the temperature regulating component 20 includes a heat conducting plate 21 and a heating film 30. A heating film 30 is provided on both sides of the heat conducting plate 21 in the thickness direction, and the heating film 30 is thermally connected or in thermal contact with the battery cell 11. For example, the heating film 30 includes a heating area 36 having a heating structure 33, and the heating area 36 is thermally connected or in thermal contact with the battery cell 11. By providing the temperature regulating component 20, the temperature regulating component 20 can regulate the temperature of the battery cell 11, and can enable the battery cell 11 to work within its normal temperature range, which can improve the working efficiency and service life of the battery cell 11 to a certain extent.

[0080] The temperature regulating component 20 includes a heat conducting plate 21 and a heating film 30. The heating films 30 are provided on both sides of the heat conducting plate 21 in the thickness direction. The heating films 30 are thermally connected or in thermal contact with the battery cells 11. For example, the heating film 30 includes a heating area 36 having a heating structure 33. The heating area 36 is thermally connected or in thermal contact with the battery cells 11, and can transfer heat to the battery cells 11 to heat the battery cells 11. The heating films 30 are provided on both sides of the thickness direction of the heat conducting plate 21, so that the temperature regulating component 20 between the two battery cell rows 10 can heat the two battery cell rows 10 at the same time, thereby making the temperature regulating component 20 have a higher heating efficiency.

[0081] Optionally, the thermal contact between the heating film 30 or the heating area 36 and the battery cell 11 may include that the heating film 30 or the heating area 36 can be in direct contact with the battery cell 11 to form a thermal contact, so that heat transfer can be performed, thereby controlling the temperature of the battery cell 11 within a normal operating temperature.

[0082] Optionally, the thermal connection between the heating film 30 or the heating area 36 and the battery cell 11 may include a thermal conductive layer disposed between the heating film 30 or the heating area 36 and the battery cell 11, and the thermal connection is performed through the thermal conductive layer. For example, the thermal conductive layer may be a thermal conductive adhesive layer 35, thermal conductive silicone grease, or a thermal conductive pad to ensure the heat transfer effect between the heating film 30 or the heating area 36 and the battery cell 11.

[0083] In addition, by arranging the heating film 30 on the heat conducting plate 21, since the heat conducting plate 21 has good thermal conductivity, the heat of the heating film 30 can be transmitted through the heat conducting effect of the heat conducting plate 21, thereby avoiding the phenomenon of local over-temperature caused by local concentration of heat on the temperature regulating component 20, thereby avoiding the situation of dry burning of the heating film 30. The heat conducting plate 21 can be a metal plate, for example, the heat conducting plate 21 can be an aluminum plate, a copper plate, etc. The heat conducting plate 21 can be a heat spreader, which can better avoid the phenomenon of local over-temperature caused by local concentration of heat on the temperature regulating component 20.

[0084] According to the battery assembly 100 of the embodiment of the utility model, by setting the above-mentioned temperature adjustment component 20, the heating area of ​​the temperature adjustment component 20 is larger, so that the heating efficiency of the temperature adjustment component 20 is higher, and a temperature adjustment component 20 is arranged between two adjacent battery cell rows 10 of the battery assembly 100. The temperature adjustment component 20 includes a heat conducting plate 21 and a heating film 30. The heating film 30 is thermally connected or thermally contacted with the battery cell 11, and can transfer heat to the battery cell 11 to heat the battery cell 11. The heating film 30 is provided on both sides of the heat conducting plate 21 in the thickness direction, so that the temperature adjustment component 20 between the two battery cell rows 10 can heat the two battery cell rows 10 at the same time, thereby improving the heating efficiency of the battery cell 11.

[0085] Reference Figure 1-Figure 2 According to some embodiments of the present invention, the heating film 30 is in direct contact with the battery cell 11, and the heating film 30 is in direct contact with the battery cell 11, thereby forming a thermal contact between the heating film 30 and the battery cell 11. The heating film 30 of the temperature adjustment component 20 is in direct thermal contact with the battery cell 11, which can achieve direct heat exchange between the heating film 30 and the battery cell 11 through direct contact, reduce the loss in the heat exchange process, and make the temperature adjustment component 20 have a higher heating efficiency, and can quickly increase the temperature of the battery cell 11, which is beneficial to improve the performance of the battery pack.

[0086] For example, the heating film 30 includes a heating area 36, ​​and the heating area 36 of the heating film 30 is in direct contact with the battery cell 11. The heating area 36 of the heating film 30 is in direct contact with the battery cell 11, thereby forming a thermal contact between the heating area 36 and the battery cell 11. The heating area 36 of the temperature adjustment component 20 is in direct thermal contact with the battery cell 11, so that direct heat exchange can be achieved between the heating area 36 and the battery cell 11 through direct contact, reducing the loss in the heat exchange process, and making the temperature adjustment component 20 have a higher heating efficiency, and can quickly increase the temperature of the battery cell 11, which is beneficial to improving the performance of the battery pack.

[0087] Reference Figure 1-Figure 2 According to some embodiments of the present invention, the heating film 30 is in direct contact with the battery cell 11, and the heat conducting plate 21 is a heat spreader. The heating film 30 is in direct contact with the battery cell 11, which can realize the heating function of the battery cell 11 and has a high heating efficiency. At the same time, the heat spreader has good thermal conductivity and a relatively uniform heat flux, which can transfer and balance the heat of the heating film 30, so that the heating effect of the temperature adjustment component 20 is relatively uniform.

[0088] Reference Figure 1-Figure 2 According to some embodiments of the utility model, the surfaces of the battery cell 11 on both sides opposite to each other along the first direction include a battery cell contact surface 12, and the battery cell contact surface 12 refers to the surface of the battery cell 11 that is in direct or indirect contact with the temperature adjustment component 20. The heating film 30 or the heating area 36 is thermally connected or thermally contacted with the battery cell contact surface 12. The area of ​​the surfaces of the battery cell 11 on both sides opposite to each other along the first direction is larger, which can increase the area of ​​heat transfer between the temperature adjustment component 20 and the battery cell 11, thereby improving the heat dissipation efficiency of the temperature adjustment component 20.

[0089] The dimension S of the heat conducting plate 21 in the third direction (refer to the direction e3 in the drawing) is Figure 3 ) and the dimension L of the battery cell 11 in the third direction (refer to Figure 3) is in the range of 50% to 80%. For example, the ratio of the size of the heat conducting plate 21 in the third direction to the size of the battery cell 11 in the third direction can be 50%, 60%, 70%, 80%, etc. The third direction, the second direction and the first direction intersect each other, for example, the third direction, the second direction and the first direction are perpendicular to each other. If the ratio of the size of the heat conducting plate 21 in the third direction to the size of the battery cell 11 in the third direction is less than 50%, the area of ​​the heat conducting plate 21 will be small, resulting in poor heating effect of the temperature regulating component 20; if the ratio of the size of the heat conducting plate 21 in the third direction to the size of the battery cell 11 in the third direction is greater than 80%, the area of ​​the heat conducting plate 21 will be large, resulting in high cost of the stabilizing regulating component and large space occupancy of the temperature regulating component 20.

[0090] By setting the ratio of the size of the heat conducting plate 21 in the third direction to the size of the battery cell 11 in the third direction to be in the range of 50% to 80%, the area of ​​the temperature regulating component 20 is made moderate, so that the temperature regulating component 20 has a higher heating efficiency and can make full use of the space, making the structure of the battery assembly 100 more compact.

[0091] Reference Figure 1-Figure 2 According to some embodiments of the utility model, a single row of battery cells 10 is provided with a plurality of temperature collection points, and the plurality of temperature collection points on a single battery cell row 10 are arranged at intervals along the second direction. By arranging a plurality of temperature collection points at intervals along the second direction on the battery cell row 10, the temperature change of the battery cells 11 in the battery cell row 10 can be obtained more accurately and comprehensively, and then the temperature adjustment component 20 can be adjusted conveniently to ensure that the battery cells 11 in the battery cell row 10 can all work at a normal working temperature, reducing or avoiding the occurrence of uneven temperature of the battery cells 11 in the battery cell row 10.

[0092] The ratio of the number of temperature collection points of a single-row battery cell row 10 to the number of battery cells 11 of the single-row battery cell row 10 is 1 / 4 to 1 / 2. For example, the ratio of the number of temperature collection points of a single-row battery cell row 10 to the number of battery cells 11 of the single-row battery cell row 10 can be 1 / 4, 5 / 16, 7 / 16, 1 / 2, etc. If the ratio of the number of temperature collection points of a single-row battery cell row 10 to the number of battery cells 11 of the single-row battery cell row 10 is less than 1 / 4, the number of temperature collection points will be small, and the temperature change of the battery cell row 10 cannot be accurately obtained; if the ratio of the number of temperature collection points of a single-row battery cell row 10 to the number of battery cells 11 of the single-row battery cell row 10 is greater than 1 / 2, the number of temperature collection points will be large, which will increase the production cost of the battery cell row 10.

[0093] By setting the ratio of the number of temperature collection points of a single-row battery cell row 10 to the number of battery cells 11 in the single-row battery cell row 10 to 1 / 4 to 1 / 2, the temperature changes of the battery cells 11 in the battery cell row 10 can be obtained more accurately and comprehensively. At the same time, it can avoid the situation where the number of temperature collection points on a single battery cell row 10 is too large, which leads to an increase in the production cost of the single-row battery cell row 10.

[0094] Reference Figure 1 as well as Figure 5 According to some embodiments of the utility model, the heating film 30 includes a heating zone 36, and the heating zone 36 includes a plurality of sub-heating zones 37 arranged along the second direction, and the power density of at least some of the sub-heating zones 37 is different, and the power density of some of the sub-heating zones 37 may be different, or the power density of all the sub-heating zones 37 may be different. The heat dissipation speeds of the battery cells 11 located at different positions in the battery cell row 10 are different, for example, the heat dissipation speed of the battery cells 11 located at both ends of the battery cell row 10 is relatively large, and the heat dissipation speed of the battery cells 11 located in the middle of the battery cell row 10 is relatively small. By arranging a plurality of sub-heating zones 37 along the second direction of the heating zone 36, and at least some of the sub-heating zones 37 have different power densities, the heat dissipation speeds of the battery cells 11 at different positions can be balanced, so that the battery cells 11 in the battery cell row 10 form a relatively uniform temperature rise speed, so that the heating zone 36 can heat the battery cells 11 of the battery cell row 10 more evenly.

[0095] In addition, by providing a plurality of sub-heating zones 37, when the heating zone 36 is partially damaged or fails, it is convenient to replace and repair the heating zone 36, thereby reducing the maintenance cost. For example, when the heating zone 36 is partially damaged or fails, only the sub-heating zone 37 corresponding to the damaged or failed portion can be replaced, without replacing or repairing the entire heating zone 36.

[0096] Reference Figure 1 as well as Figure 5 According to some embodiments of the present invention, in the second direction, the power density of the sub-heating zone 37 located in the middle of the battery cell row 10 is greater than the power density of the sub-heating zone 37 located at the two ends of the battery cell row 10. The battery cells 11 located at the two ends of the battery cell row 10 have fewer battery cells 11 around them, and the heat dissipation speed of the battery cells 11 is faster; the battery cells 11 located in the middle of the battery cell row 10 have more battery cells 11 around them, and the heat dissipation speed of the battery cells 11 is slower. By setting the power density of the sub-heating zone 37 located in the middle of the battery cell row 10 to be greater than the power density of the sub-heating zone 37 located at the two ends of the battery cell row 10, the heat dissipation speed of the battery cells 11 at different positions can be balanced, so that the battery cells 11 in the middle of the battery cell row 10 and the battery cells 11 at the two ends of the battery cell row 10 form a relatively uniform temperature rise speed, so that the temperature difference of the battery cells 11 at different positions of the battery cell row 10 can be smaller.

[0097] Reference Figure 1 as well as Figure 5 According to some embodiments of the present invention, the plurality of sub-heating zones 37 include two first sub-heating zones 371, two second sub-heating zones 372, two third sub-heating zones 373 and one fourth sub-heating zone 374. The fourth sub-heating zone 374 is located in the middle of the battery cell row 10 along the second direction. In the second direction, from the middle of the battery cell row 10 to the two ends of the battery cell row 10, the fourth sub-heating zone 374, the third sub-heating zone 373, the second sub-heating zone 372 and the first sub-heating zone 371 are arranged sequentially and the power density increases sequentially. In the direction from the middle of the battery cell row 10 to the two ends of the battery cell row 10, the heat dissipation rate of the battery cells 11 in the battery cell row 10 gradually increases, by setting two first sub-heating zones 371, two second sub-heating zones 372, two third sub-heating zones 373 and one fourth sub-heating zone 374, and in the direction from the middle of the battery cell row 10 to the two ends of the battery cell row 10, the fourth sub-heating zone 374, the third sub-heating zone 373, the second sub-heating zone 372 and the first sub-heating zone 371 are arranged in sequence and the power density increases in sequence, so that the heating zone 36 can adapt to the battery cells 11 with different heat dissipation rates in the battery cell row 10, so that the heating zone 36 can heat the battery cells 11 of the battery cell row 10 more evenly.

[0098] Reference Figure 1 as well as Figure 5 According to some embodiments of the utility model, in the second direction, the ratio of the size of the second sub-heating zone 372 to the size of the first sub-heating zone 371 is 1.8-2, the ratio of the size of the third sub-heating zone 373 to the size of the first sub-heating zone 371 is 1.7-1.9, and the ratio of the size of the fourth sub-heating zone 374 to the size of the first sub-heating zone 371 is 2.3-3.6. In the direction from the middle of the battery cell row 10 to the two ends of the battery cell row 10, the number of battery cells 11 with slower heat dissipation in the middle is large, and the space occupied is the largest, the number of battery cells 11 with faster heat dissipation at the two ends is small, and the space occupied is small. The battery cells 11 in the middle section from the middle to the two ends can be divided into two areas according to the heat dissipation speed of the battery cells 11, and the number of battery cells 11 in each area is more than the number of battery cells 11 with faster heat dissipation at the two ends and less than the number of battery cells 11 with slower heat dissipation in the middle, and the space occupied is large.

[0099] By setting the size ratio of the second sub-heating zone 372 to the size ratio of the first sub-heating zone 371 to 1.8-2, the size ratio of the third sub-heating zone 373 to the size ratio of the first sub-heating zone 371 to 1.7-1.9, and the size ratio of the fourth sub-heating zone 374 to the size ratio of the first sub-heating zone 371 to 2.3-3.6, the heating zone 36 is divided more reasonably, so that the heating zone 36 can be adapted to the battery cells 11 with different heat dissipation speeds in the battery cell row 10, so that the heating zone 36 can heat the battery cells 11 of the battery cell row 10 more evenly.

[0100] Reference Figure 1 as well as Figure 5 According to some embodiments of the present invention, the heating film 30 includes a heating structure 33 and an insulating heat-conducting film 31, and the heating structure 33 is connected to the side of the insulating heat-conducting film 31 facing the heat-conducting plate 21. The heating film 30 includes a heating structure 33 and an insulating heat-conducting film 31, and the heating structure 33 and at least a part of the insulating heat-conducting film 31 constitute a heating area 36. The heating film 30 is connected to the heat-conducting plate 21 through the adhesive layer, and at the same time, the heating structure 33 connected to the side of the insulating heat-conducting film 31 facing the heat-conducting plate 21 can be fixed to the heat-conducting plate 21, so that the assembly is relatively simple and the connection is relatively stable.

[0101] The heating structure 33 includes a plurality of sub-heating structures, which are sequentially arranged in series or in parallel, and the number of the sub-heating structures is the same as the number of the sub-heating zones 37 and corresponds to each other. The plurality of sub-heating structures are sequentially arranged in series or in parallel, and the connection method is relatively simple, and the heating zone 36 can be conveniently divided into a plurality of sub-heating zones 37 with different power densities.

[0102] For example, the heating structure 33 is a heating wire, and the resistance of the heating wire can be adjusted by adjusting the cross-sectional area of ​​the heating wire, so that different sub-heating areas 37 corresponding to different heating wires have different power densities. If multiple heating wires are arranged in series, the larger the cross-sectional area of ​​the heating wire, the smaller the resistance of the heating wire, and the smaller the power density of the heating area 36 corresponding to the heating wire; if multiple heating wires are arranged in parallel, the larger the cross-sectional area of ​​the heating wire, the smaller the resistance of the heating wire, and the larger the power density of the heating area 36 corresponding to the heating wire.

[0104] According to the vehicle of the embodiment of the utility model, by setting the above-mentioned battery assembly 100, a temperature adjustment component 20 is arranged between two adjacent battery cell rows 10 of the battery assembly 100, and the temperature adjustment component 20 includes a heat conducting plate 21 and a heating film 30. The heating film 30 is thermally connected or thermally contacted with the battery cell 11, and can transfer heat to the battery cell 11 to heat the battery cell 11. The heating film 30 is arranged on both sides of the heat conducting plate 21 in the thickness direction, so that the temperature adjustment component 20 between the two battery cell rows 10 can heat the two battery cell rows 10 at the same time, thereby improving the heating efficiency of the battery cell 11.
