As shown in fig. 1, in an embodiment of the present utility model, a battery pack according to the present utility model includes a case 100 and a first heat exchange plate 200. Referring to fig. 2 to 4 in combination, an exploded perspective view of a battery pack, specifically, a first heat exchange plate 200 is separated from a case 100 is representatively shown in fig. 2; a schematic perspective view of the case 100 is representatively illustrated in fig. 3; a schematic perspective view of the first heat exchange plate 200 is representatively illustrated in fig. 4. The structure, connection manner and functional relationship of the main components of the battery pack according to the present utility model will be described in detail with reference to the above drawings.
As shown in fig. 1 to 3, in an embodiment of the present utility model, the case 100 has a box-shaped structure with an open top, and the case 100 has a battery compartment 101 and an electrical compartment 102, the battery compartment 101 accommodates a battery, and the electrical compartment 102 accommodates an electrical component (e.g., BMS, etc.). The first heat exchange plate 200 is hermetically connected to the top opening of the battery compartment 101 such that the first heat exchange plate 200 seals the battery compartment 101 as a part of the cover plate of the battery pack. The first heat exchange plate 200 extends to the upper side of the electrical bin 102 partially, and a part of the top opening of the electrical bin 102 is covered by the first heat exchange plate 200, and a first liquid inlet and outlet connector 300 is connected to the part of the first heat exchange plate 200 extending to the electrical bin 102, and the first liquid inlet and outlet connector 300 is located in the electrical bin 102. Through the structural design, the heat exchange function of the first heat exchange plate 200 on the battery accommodated in the battery compartment 101 can be guaranteed, the heat exchange efficiency is improved on the basis, and the design redundancy is reduced. Meanwhile, the utility model can utilize the spare space in the electric bin 102 to accommodate the first liquid inlet and outlet connector 300, so that the first liquid inlet and outlet connector 300 is prevented from being arranged in the battery bin 101 to occupy the battery arrangement space, and meanwhile, the occupied space of the battery pack is prevented from being increased due to the fact that the first liquid inlet and outlet connector 300 is arranged outside the box body 100.
In the embodiment shown in fig. 1 to 3, the case 100 is a box-shaped structure with an open top, and the first heat exchange plate 200 is hermetically connected to the top opening of the battery compartment 101. In some embodiments of the present utility model, the case 100 may also have a box-shaped structure with an open bottom, and the first heat exchange plate 200 is hermetically connected to the bottom opening of the battery compartment 101. On this basis, the first heat exchange plate 200 extends partially below the electrical cabinet 102, and a portion of the bottom opening of the electrical cabinet 102 is covered by the first heat exchange plate 200.
As shown in fig. 1 to 3, in an embodiment of the present utility model, the case 100 includes a rim 110, and the rim 110 encloses an outer peripheral outline of an inner cavity of the case 100. A partition beam 120 is provided in the inner cavity of the case 100, and the partition beam 120 partitions the inner cavity of the case 100 into a battery compartment 101 and an electrical compartment 102. On this basis, the first heat exchange plate 200 may be hermetically coupled to the top of the partition beam 120 and the top of a portion of the frame 110. Through the structural design, the utility model can ensure the whole sealing connection between the first heat exchange plate 200 and the peripheral outline of the battery compartment 101, thereby further optimizing the sealing performance of the battery pack. In some embodiments, when the case 100 is a box-shaped structure with an open bottom and the first heat exchange plate 200 is hermetically connected to the bottom opening of the battery compartment 101, the first heat exchange plate 200 may be hermetically connected to the bottom of the partition beam 120 and the bottom of a portion of the frame 110.
As shown in fig. 1, 2 and 4, in an embodiment of the present utility model, the first heat exchange plate 200 may have a body portion 210 and a protrusion portion 220. Specifically, the body portion 210 corresponds to the battery compartment 101, that is, the first heat exchange plate 200 closes the top opening of the battery compartment 101 with the body portion 210, and the protrusion 220 protrudes from the body portion 210 toward one side of the electrical compartment 102 and is located above the electrical compartment 102. On this basis, the heat exchange flow channel 201 of the first heat exchange plate 200 extends to the protrusion 220, and the first liquid inlet and outlet connector 300 is connected to the heat exchange flow channel 201 of the protrusion 220. Through the above structural design, the utility model can be connected with the first liquid inlet and outlet connector 300 accommodated in the electric bin 102 by utilizing the convex part 220 on the basis of utilizing the body part 210 to seal the battery bin 101, thereby facilitating the arrangement and connection of the first liquid inlet and outlet connector 300 and further optimizing the structural rationality of the battery pack. In some embodiments, when the case 100 is a box-shaped structure with an open bottom and the first heat exchange plate 200 is connected to the bottom opening of the battery compartment 101 in a sealing manner, the body portion 210 is used to close the bottom opening of the battery compartment 101, and the protrusion 220 protrudes from the body portion 210 toward one side of the electrical compartment 102 and is located below the electrical compartment 102.
As shown in fig. 1, 2 and 4, based on the structural design that the first heat exchange plate 200 has the body portion 210 and the protrusion portion 220, in an embodiment of the present utility model, the protrusion portion 220 and the body portion 210 may be located at the same horizontal plane. Through the structural design, the heat exchange flow channel 201 extending to the protruding part 220 can be prevented from being bent due to the influence of the height difference along the height direction of the battery pack, so that the heat exchange effect is improved without increasing flow resistance caused by bending of the part of the heat exchange flow channel 201.
As shown in fig. 3 and 4, based on the structural design that the first heat exchange plate 200 has the body portion 210 and the protruding portion 220, in an embodiment of the present utility model, the electrical compartment 102 is located at one side of the battery compartment 101 along the first direction X, that is, the electrical compartment 102 and the battery compartment 101 are aligned along the first direction X. On this basis, the length L1 of the protrusion 220 of the first heat exchange plate 200 protruding in the first direction X may be smaller than the length L2 of the electrical warehouse 102 in the first direction X. Accordingly, a gap exists between an end of the protrusion 220 facing away from the battery compartment 101 (i.e., an end facing away from the body portion 210) and a side wall of the electrical compartment 102 facing away from the battery compartment 101, i.e., the protrusion 220 does not cover the entire electrical compartment 102 along the first direction X. Through the structural design, a gap is reserved between the protruding part 220 and the electrical bin 102, so that the protruding part 220 and a liquid inlet and outlet interface are conveniently arranged, and interference with the bin wall of the electrical bin 102 is avoided.
Referring to fig. 5 and 6, a schematic perspective view of a battery pack in another exemplary embodiment that can embody principles of the present utility model is representatively illustrated in fig. 5; an exploded perspective view of the battery pack shown in fig. 5 is representatively illustrated in fig. 6, in which the protective cover 400 is separated from the case 100.
As shown in fig. 5 and 6, taking the structural design of the first heat exchange plate 200 with the body portion 210 and the protruding portion 220 as an example, in an embodiment of the present utility model, the battery pack according to the present utility model may further include a protection cover 400, where the protection cover 400 is sealingly connected to the top opening of the electrical cabinet 102, so that the protection cover 400 seals the electrical cabinet 102. Through the above structural design, the protection cover 400 can be utilized to seal the electrical bin 102, and accordingly, the protection cover 400 and the first heat exchange plate 200 together form a box cover of the battery pack. In some embodiments, when the case 100 is a box-shaped structure with an open bottom and the first heat exchange plate 200 is hermetically connected to the bottom opening of the battery compartment 101, the protection cover 400 may also be hermetically connected to the bottom opening of the electrical compartment 102.
As shown in fig. 5 and 6, based on the structural design that the battery pack includes the protective cover 400, in one embodiment of the present utility model, when the case 100 includes the frame 110 and the partition beams 120, the protective cover 400 may be hermetically coupled to the top of the partition beams 120 and the top of a portion of the frame 110. In other words, the top of one portion of the rim 110 is sealingly connected with the first heat exchange plate 200, and the top of the other portion of the rim 110 is sealingly connected with the protective cover 400. Through the structural design, the utility model can ensure the whole sealing connection between the protective cover 400 and the peripheral outline of the electric bin 102, thereby further optimizing the sealing performance of the battery pack.
Referring to fig. 7, there is representatively illustrated an exploded perspective view of a portion of the structure of a battery pack capable of embodying the principles of the present utility model in yet another exemplary embodiment, in which the structure in which the first heat exchange plate 200 is separated from the protective cover 400 is specifically illustrated in fig. 7.
As shown in fig. 7, still taking a structural design in which the first heat exchange plate 200 includes the protrusion 220 and the battery pack includes the protection cover 400 as an example, in an embodiment of the present utility model, the protection cover 400 may be hermetically connected to the protrusion 220 of the first heat exchange plate 200. By the above structural design, since the protruding part 220 extends to the upper side of the electrical bin 102, the sealing effect between the protective cover 400 and the protruding part 220 can be further ensured, and accordingly, the sealing performance of the battery pack is further ensured.
As shown in fig. 5 to 7, based on the structural design that the protective cover 400 is connected to the protrusion 220 in a sealing manner, in an embodiment of the present utility model, a side of the protective cover 400 facing the first heat exchange plate 200 may be provided with a groove 410, the shape of the groove 410 matches the shape of the protrusion 220, the protrusion 220 is accommodated in the groove 410, and the groove 410 is connected to the protrusion 220 in a sealing manner. Through the above structural design, the present utility model can utilize the groove 410 to accommodate the protrusion 220, and save space occupation in the height direction on the basis of ensuring the sealing connection between the protective cover 400 and the protrusion 220. In some embodiments, when the protection cover 400 is sealingly connected to the top opening of the electrical cabinet 102, the protection cover 400 may also cover the top of the protrusion 220, and then the bottom surface of the protection cover 400 may be sealingly connected to the top surface of the protrusion 220, or when the protection cover 400 is sealingly connected to the bottom opening of the electrical cabinet 102, the protection cover 400 may also cover the bottom of the protrusion 220, and then the top surface of the protection cover 400 may be sealingly connected to the bottom surface of the protrusion 220, which is not limited in this embodiment.
It should be noted that, in some embodiments of the present utility model, the sealing connection may be implemented by adopting the structural form of a sealing gasket or a sealing ring for the structural designs of the above-mentioned "the first heat exchange plate 200 is in sealing connection with the top opening of the battery compartment 101", "the protection cover 400 is in sealing connection with the top opening of the electrical compartment 102", and "the groove 410 of the protection cover 400 is in sealing connection with the protrusion 220 of the first heat exchange plate 200".
