[0027] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0028] like Figure 1As shown, the integrated energy unit 1 of the embodiment of the present disclosure includes a shell 11, a vehicle-mounted power system (charger converter unit, referred to as CCU) 12 and a battery distribution system (Battery energy Distribution Unit, referred to as BDU) 13. The vehicle-mounted power system 12 and the battery distribution system 13 are both arranged in the shell 11, and the vehicle-mounted power system 12 is electrically connected to the battery distribution system 13.

[0029] The integrated energy unit 1 of the disclosed embodiment integrates the vehicle-mounted power supply system 12 and the battery power distribution system 13 into one by placing both the vehicle-mounted power supply system 12 and the battery power distribution system 13 in the same housing 11. When installing the vehicle-mounted power supply system 12 and the battery power distribution system 13, it is only necessary to fix the housing 11 in a preset position (for example, in the box of the battery pack) to simultaneously realize the installation and fixation of the vehicle-mounted power supply system 12 and the battery power distribution system 13. Moreover, since the vehicle-mounted power supply system 12 and the battery power distribution system 13 are electrically connected, the electrical connection operation between the vehicle-mounted power supply system 12 and the battery power distribution system 13 can be avoided at the installation site. Thus, the installation efficiency of the vehicle-mounted power supply system 12 and the battery power distribution system 13 can be improved.

[0030] In the related art, electrical connectors are usually provided on the vehicle power system and the battery power distribution system, and the vehicle power system and the battery power distribution system are electrically connected through a wiring harness with an insulating layer. The cost of the electrical connector is high, which leads to high costs for the vehicle power system and the battery power distribution system.

[0031] Optionally, the vehicle power supply system 12 and the battery power distribution system 13 are electrically connected via a connecting bar.

[0032] The connecting bar may be a copper bar, an aluminum bar, or the like.

[0033] It is understandable that when the vehicle-mounted power supply system 12 and the battery power distribution system 13 are both disposed in the housing 11, the electrical connection components between the vehicle-mounted power supply system 12 and the battery power distribution system 13 are located in the housing 11, and it is not necessary to insulate the electrical connection components between the vehicle-mounted power supply system 12 and the battery power distribution system 13. This allows the electrical connection between the vehicle-mounted power supply system 12 and the battery power distribution system 13 to be achieved through the connecting bar.

[0034] As a result, it is possible to save the need to arrange electrical connectors on the onboard power supply system 12 and the battery power distribution system 13 , thereby reducing the cost of the integrated energy unit 1 .

[0035] It is understandable that the vehicle power system 12 and the battery distribution system 13 are both components related to charging and distribution, and both generate heat during operation. In order to ensure the reliability of the vehicle power system 12 and the battery distribution system 13, the vehicle power system 12 and the battery distribution system 13 need to be cooled and dissipated. In particular, when the charging and discharging power of the battery pack is large, the battery distribution system 13 needs to be cooled and dissipated.

[0036] In some embodiments, Figure 1 As shown, the shell 11 is provided with a heat exchange flow channel 114 , a flow channel inlet 115 and a flow channel outlet 116 , and the flow channel inlet 115 and the flow channel outlet 116 are both in communication with the heat exchange flow channel 114 .

[0037] In specific use, the heat exchange medium can be introduced into the heat exchange channel 114 through the channel inlet 115, and the heat exchange medium exchanges heat with the vehicle power system 12 and / or the battery distribution system 13 in the heat exchange channel 114, and then flows out through the channel outlet 116. The heat exchange medium can be a heating medium or a cooling medium. When the heat exchange medium is a heating medium, the temperature of the heating medium is higher than that of the integrated energy unit 1, and the heating medium can be used to heat the integrated energy unit 1; when the heat exchange medium is a cooling medium, the temperature of the cooling medium is lower than that of the integrated energy unit 1, and the cooling medium can be used to cool and dissipate heat of the integrated energy unit 1.

[0038] For the convenience of description, the heat exchange medium is taken as a cooling medium as an example. After the heat exchange medium flows through the heat exchange channel 114, the vehicle power system 12 and / or the battery distribution system 13 can be cooled and dissipated. The heat exchange medium can be liquid or gas.

[0039] By providing a heat exchange channel 114 in the shell 11 to cool and dissipate heat for the integrated energy unit 1 , the heat dissipation efficiency of the integrated energy unit 1 can be improved, thereby improving the reliability of the integrated energy unit 1 .

[0040] In the related art, the vehicle power system is usually equipped with a water cooling structure. When the charging and discharging power of the battery pack is large, the battery distribution system also needs to be equipped with a water cooling structure. The battery distribution system and the vehicle power system are usually connected through a water nozzle and a water pipe so that the coolant of the vehicle power system can enter the battery distribution system. The setting of the water nozzle and the water pipe between the battery distribution system and the vehicle power system not only increases the structural complexity of the system, but also increases the cost of the system.

[0041] Alternatively, if Figure 1 As shown, a portion of the heat exchange channel 114 is disposed in the vehicle power system 12 , and another portion of the heat exchange channel 114 is disposed in the battery power distribution system 13 .

[0042] By arranging a part of the heat exchange channel 114 in the vehicle power system 12, the heat exchange medium flowing through the heat exchange channel 114 can take away the heat of the vehicle power system 12, thereby realizing cooling and heat dissipation of the vehicle power system 12; by arranging another part of the heat exchange channel 114 in the battery distribution system 13, the heat exchange medium flowing through the heat exchange channel 114 can take away the heat of the battery distribution system 13, thereby realizing cooling and heat dissipation of the battery distribution system 13.

[0043] As a result, the vehicle power system 12 and the battery distribution system 13 share the same cooling system, thereby avoiding the need to provide a water nozzle and a water pipe between the battery distribution system 13 and the vehicle power system 12, which is beneficial to reducing the number of components of the integrated energy unit 1, reducing the volume of the integrated energy unit 1 and reducing the cost of the integrated energy unit 1.

[0044] Alternatively, if Figure 1 As shown, the heat exchange channel 114 includes a first channel section 1141 and a second channel section 1142 that are connected, the channel inlet 115 is provided at the first channel section 1141, and the channel outlet 116 is provided at the second channel section 1142. A portion of the first channel section 1141 is provided in the vehicle power system 12, another portion of the first channel section 1141 is provided in the battery power distribution system 13, a portion of the second channel section 1142 is provided in the vehicle power system 12, and another portion of the second channel section 1142 is provided in the battery power distribution system 13.

[0045] It can be understood that after the heat exchange medium enters the heat exchange channel 114 from the channel inlet 115, it first flows through the first channel section 1141, then flows through the second channel section 1142, and then flows out through the channel outlet 116. Therefore, the temperature of the heat exchange medium in the first channel section 1141 is different from the temperature of the heat exchange medium in the second channel section 1142, so that the heat exchange efficiency at the first channel section 1141 and the second channel section 1142 is also different.

[0046] Through the above design of the first flow channel section 1141 and the second flow channel section 1142, the vehicle power system 12 and the battery power distribution system 13 can both exchange heat with the heat exchange medium in the first flow channel section 1141, and the vehicle power system 12 and the battery power distribution system 13 can both exchange heat with the heat exchange medium in the second flow channel section 1142. This is beneficial to improve the uniformity of heat exchange between the vehicle power system 12 and the battery power distribution system 13 and the heat exchange medium in the heat exchange flow channel 114, avoid a large temperature difference between the vehicle power system 12 and the battery power distribution system 13, and achieve uniform cooling of the vehicle power system 12 and the battery power distribution system 13.

[0047] Alternatively, if Figure 1As shown, the heat exchange channel 114 is U-shaped, and the extension direction of the first channel section 1141 and the second channel section 1142 is consistent. The heat exchange channel 114 also includes a third channel section 1143, and the two ends of the third channel section 1143 are respectively connected to the first channel section 1141 and the second channel section 1142, and the extension direction of the third channel section 1143 intersects with the first channel section 1141. The vehicle power system 12 is arranged on one side of the battery distribution system 13 in the extension direction of the first channel section 1141.

[0048] For example, Figure 1 As shown, the first flow channel section 1141 and the second flow channel section 1142 both extend in the left-right direction, and the vehicle power supply system 12 is arranged on the right side of the battery power distribution system 13. The heat exchange medium enters the first flow channel section 1141 through the flow channel inlet 115, and flows through the battery power distribution system 13 and the vehicle power supply system 12 in sequence from left to right; then flows through the third flow channel section 1143; then enters the second flow channel section 1142, and flows through the vehicle power supply system 12 and the battery power distribution system 13 in sequence from right to left.

[0049] It can be understood that, in the heat exchange channel 114, along the extension direction of the heat exchange channel 114, the closer the heat exchange medium is to the channel inlet 115, the lowest temperature, the higher the heat exchange efficiency with the integrated energy unit 1, and the more conducive to cooling and dissipating the integrated energy unit 1; while the closer the heat exchange medium is to the channel outlet 116, the higher the temperature, the lower the heat exchange efficiency with the integrated energy unit 1, and the less conducive to cooling and dissipating the integrated energy unit 1.

[0050] The above-mentioned design of the first flow channel section 1141, the second flow channel section 1142, the third flow channel section 1143, the vehicle power system 12 and the battery distribution system 13 enables the cooling medium closest to the flow channel inlet 115 and the cooling medium closest to the flow channel outlet 116 to flow through one of the vehicle power system 12 and the battery distribution system 13, and the other part of the cooling medium flows through the other of the vehicle power system 12 and the battery distribution system 13. That is, the cooling medium with higher heat exchange efficiency and lower heat exchange efficiency flows through one of the vehicle power system 12 and the battery distribution system 13; and the cooling medium with intermediate heat exchange efficiency flows through the other of the vehicle power system 12 and the battery distribution system 13. In this way, the temperature difference between the vehicle power system 12 and the battery distribution system 13 can be further reduced, and uniform cooling of the vehicle power system 12 and the battery distribution system 13 can be achieved.

[0051] Optionally, a portion of the housing 11 forms a housing of the vehicle power system 12 , and another portion of the housing 11 forms a housing of the battery power distribution system 13 .

[0052] For example, the housing 11 is a die-casting. The housing 11 is used as both the housing of the vehicle power system 12 and the housing of the battery power distribution system 13. That is, the electrical components of the vehicle power system and the battery power distribution system in the prior art are directly installed in the housing 11, so that the vehicle power system 12 and the battery power distribution system 13 form a whole. In short, the vehicle power system 12 and the battery power distribution system 13 share the same housing.

[0053] By using the vehicle power system 12 and the battery power distribution system 13 to share the same housing 11 , it is helpful to simplify the overall structure consisting of the vehicle power system 12 and the battery power distribution system 13 , thereby further reducing the cost of the integrated energy unit 1 .

[0054] like Figure 2 and Figure 3 As shown, the battery of the embodiment of the present disclosure includes a box, multiple battery cells and an integrated energy unit 1, and the battery cell 2 is arranged in the box; the integrated energy unit 1 is the integrated energy unit 1 described in any of the above embodiments, and the battery distribution system 13 is electrically connected to the battery cell 2.

[0055] Since the installation efficiency of the on-board power supply system 12 and the battery power distribution system 13 is high, the assembly efficiency of the battery pack is high.

[0056] Alternatively, if Figure 2 and Figure 3 As shown, the integrated energy unit 1 is arranged in a box.

[0057] The integrated energy unit 1 is arranged in a box body, and the box body can be used to protect the integrated energy unit 1, thereby improving the safety of the integrated energy unit 1 and thus improving the safety of the battery pack.

[0058] Optionally, a first joint is provided on the outer side of the box body, and the first joint includes a first inlet and a first outlet, the first inlet is connected to the flow channel inlet 115 , and the first outlet is connected to the flow channel outlet 116 .

[0059] For example, Figure 1 As shown, the flow channel inlet 115 is connected to one end of the first connecting tube 14, and the other end of the first connecting tube 14 is connected to the first inlet, thereby realizing the connection between the first inlet and the flow channel inlet 115; the flow channel outlet 116 is connected to one end of the second connecting tube 15, and the other end of the second connecting tube 15 is connected to the first outlet, thereby realizing the connection between the first outlet and the flow channel outlet 116.

[0060] By providing the first joint on the outside of the box, the heat exchange channel 114 can be connected to the heat exchange medium through a pipeline on the outside of the box, thereby facilitating the connection between the heat exchange channel 114 and the heat exchange medium, thereby facilitating the installation of the battery pack.

[0061] Optionally, the plurality of battery cells 2 and the integrated energy unit 1 form a plurality of components, and the plurality of components are arranged at intervals along a first direction. The first direction intersects with the height direction of the box. The integrated energy unit 1 can be a component alone, or it can form a component together with at least one battery cell 2.

[0062] By forming a plurality of battery cells 2 and an integrated energy unit 1 into a plurality of components, the layout inside the box is orderly, and the plurality of battery cells 2 and the integrated energy unit 1 are conveniently installed inside the box, which is beneficial to improving the assembly efficiency of the battery pack.

[0063] In order to make the technical solution of the present disclosure easier to understand, the following takes the case where the height direction of the box is consistent with the up-down direction and the first direction is consistent with the front-back direction as an example to further describe the technical solution of the present disclosure. Figure 2 As shown, the front-to-back direction is Figure 3 shown.

[0064] For example, Figure 2 and Figure 3 As shown, there are four components, which are arranged at intervals along the front-to-back direction. The integrated energy unit 1 and the two battery cells 2 together form one component.

[0065] Alternatively, if Figure 3 As shown, a plurality of heat exchange plates 3 are provided in the box, and the plurality of heat exchange plates 3 are arranged at intervals along the first direction, and the heat exchange plates 3 and the components are arranged alternately in sequence along the first direction, and the components are in contact with adjacent heat exchange plates 3. The heat exchange plates 3 may be liquid cooling plates, and the cell side surfaces 202 of the cell 2 and the shell side surfaces 112 of the integrated energy unit 1 are in contact with the heat exchange plates 3.

[0066] By contacting the component with the adjacent heat exchange plate 3, the heat of the component can be transferred to the heat exchange plate 3 to achieve cooling, heat dissipation or heating of the component. For example, a heat exchange plate 3 is provided on the front side of the component, and the front surface of the battery cell 2 and / or the integrated energy unit 1 in the component contacts the rear surface of the heat exchange plate 3.

[0067] By arranging the heat exchange plates 3 and components alternately in sequence along the first direction, the heat exchange plates 3 and components are arranged in an orderly manner, which facilitates the assembly of the integrated energy unit 1, multiple battery cells 2 and the heat exchange plates 3, and is conducive to further improving the assembly efficiency of the battery pack.

[0068] Optionally, a potting cavity is formed between the box, the battery core 2 and the integrated energy unit 1, and the potting cavity is filled with potting glue, wherein the potting glue can be foam glue or silica gel.

[0069] By filling the potting cavity with potting glue, not only can the integrated energy unit 1 and the battery cell 2 be fixed in the container body, but also the battery cell 2 and the integrated energy unit 1 can be indirectly in contact with the heat exchange plate 3 through the potting glue, so that the heat of the battery cell 2 and the integrated energy unit 1 is transferred to the heat exchange plate 3, and the contact area between the battery cell 2 and the integrated energy unit 1 and the heat exchange plate 3 is increased, which is beneficial to improve the heat dissipation efficiency of the battery cell 2 and the integrated energy unit 1, and improve the reliability of the battery cell 2 and the integrated energy unit 1.

[0070] Alternatively, if Figure 3 As shown, one part of the components is a first component 21, the first component 21 is composed of an integrated energy unit 1, or the first component 21 is composed of an integrated energy unit 1 and at least one battery cell 2, and the integrated energy unit 1 and the battery cell 2 in the same first component 21 are arranged at intervals along the second direction. Another part of the components is a second component 22, the second component 22 is composed of multiple battery cells 2, and the multiple battery cells 2 in the same second component 22 are arranged at intervals along the second direction. The second direction intersects both the height direction of the box and the first direction.

[0071] Therefore, the integrated energy unit 1 can be regarded as a "battery cell model" and integrated with multiple battery cells 2 in the same box, which facilitates the arrangement and installation of the integrated energy unit 1 and the battery cells 2 in the box, and is conducive to further improving the assembly efficiency of the battery pack.

[0072] In order to make the technical solution of the present disclosure easier to understand, the technical solution of the present disclosure is further described below by taking the second direction being consistent with the left-right direction as an example. Figure 2 and Figure 3 shown.

[0073] For example, Figure 3 As shown, the integrated energy unit 1 and the battery cell 2 in the same first component 21 are arranged at intervals along the left-right direction, and the multiple battery cells 2 in the same second component 22 are arranged at intervals along the left-right direction.

[0074] Alternatively, if Figure 2 As shown, the top surface of the battery cell 2 is flush with the top surface of the integrated energy unit 1 , and the bottom surface of the battery cell 2 is flush with the bottom surface of the integrated energy unit 1 .

[0075] For example, Figure 2As shown, the top surface of the battery cell 2 is the battery cell top surface 201, the top surface of the shell 11 is the shell top surface 111, the shell top surface 111 is the top surface of the integrated energy unit 1, and the battery cell top surface 201 is flush with the shell top surface 111. The bottom surface of the battery cell 2 is the battery cell bottom surface 203, the bottom surface of the shell 11 is the shell bottom surface 113, the shell bottom surface 113 is the bottom surface of the integrated energy unit 1, and the battery cell bottom surface 203 is flush with the shell bottom surface 113. As an example, the lower surface of the battery cell 2 is flush with the lower surface of the integrated energy unit 1, and the upper surface of the battery cell 2 is flush with the lower surface of the integrated energy unit 1.

[0076] By aligning the top surface of the battery cell 2 with the top surface of the integrated energy unit 1, and aligning the bottom surface of the battery cell 2 with the bottom surface of the integrated energy unit 1, the battery cell 2 and the integrated energy unit 1 occupy the same size in the height direction of the box. This avoids increasing the height of the box due to arranging the integrated energy unit 1 in the box, which is beneficial to reducing the volume of the battery pack.

[0077] When designing the integrated energy unit 1 , the height of the battery cell 2 is used to limit the design height of the integrated energy unit 1 , so that the integrated energy unit 1 can be placed in the battery pack without increasing the height, and arranged side by side with the battery cell 2 .

[0078] Optionally, the heat exchange plate 3 has a fluid channel and a fluid inlet and a fluid outlet connected to the fluid channel. The box body is provided with a second joint, the second joint includes a second inlet and a second outlet, the second inlet is connected to the fluid inlet, and the second outlet is connected to the fluid outlet. The second inlet is connected in parallel with the first inlet, and the second outlet is connected in parallel with the second outlet.

[0079] Thus, the heat exchange medium can enter the heat exchange plate 3 through the fluid inlet, then flow along the fluid channel of the heat exchange plate 3, and finally flow out of the heat exchange plate 3 through the fluid to take the heat generated by the battery cell 2 and the integrated energy unit 1 out of the battery pack. This is conducive to further improving the heat dissipation efficiency of the battery cell 2 and the integrated energy unit 1, and improving the reliability of the battery cell 2 and the integrated energy unit 1. In addition, the second inlet is connected in parallel with the first inlet, and the second outlet is connected in parallel with the first outlet, so that the fluid channel and the heat exchange flow channel 114 are connected in parallel, so that the heat exchange plate 3 and the heat exchange flow channel 114 can share the same heat exchange medium, further facilitating the installation of the battery pack.

[0080] The vehicle of the embodiment of the present disclosure includes the battery pack described in any of the above embodiments, wherein the vehicle can be a pure electric vehicle or a hybrid electric vehicle.

[0081] Since the battery pack according to the embodiment of the present disclosure has advantages such as high assembly efficiency, the vehicle according to the embodiment of the present disclosure has advantages such as low cost.

[0082] Although the embodiments of the present disclosure have been shown and described above, it is to be understood that the above embodiments are illustrative and cannot be construed as limitations on the present disclosure. Changes, modifications, substitutions and variations of the above embodiments by those of ordinary skill in the art are all within the scope of protection of the present disclosure.
