In order to realize compatibility with different vehicle standards, multiple distribution schemes need to be designed, which increases the design cost of the distribution scheme and is low in standardization, which is not conducive to platformization on different vehicle models.

[0034] To solve the above problems, the embodiment of the present application provides a power distribution structure, which can improve the standardization degree of the battery pack power distribution structure and is conducive to the platformization of the power distribution structure on different vehicle models.

[0035] The technical solutions of the embodiments of the present application are described in detail below with reference to the drawings.

[0036] Figure 1 is a structural schematic diagram of the power distribution structure of the battery pack according to an embodiment of the present application.

[0037] Referring to Figure 1 The embodiment of the present application provides a power distribution structure of a battery pack. The battery pack 100 is provided with a BDU module 110 and a connector module electrically connected with the BDU module 110, and the connector module at least includes a fast charging connector 160 and a driving motor connector. The power distribution structure includes a boost module, the boost module is arranged non-integrally with respect to the power distribution structure, and the boost module is electrically connected with the fast charging connector 160, the driving motor connector and the BDU module to form a reverse boost charging circuit for charging the battery pack 100. When the boost function is needed, the boost module can be assembled on the vehicle, and the battery pack 100 can be charged through the reverse boost charging circuit. When the boost function is not needed, the boost module does not need to be assembled, so that the battery pack of the present application can meet the needs of different schemes, improve the standardization degree of the power distribution structure, and be conducive to platformization on different vehicle models.

[0038] The BDU (Battery energy Distribution Unit, battery energy distribution unit) module 110, also known as a high-voltage distribution box, is a power distribution component on the high-voltage loop of an electric vehicle. The BDU module 110 is directly connected with the power battery through a high-voltage plug-in, and is used to control the charging and discharging process of the high-voltage loop.

[0039] The BDU module 110 is provided with an electrode assembly, which includes a load negative electrode 121, a fast charging negative electrode 122, a fast charging positive electrode 123, a load positive electrode 124, a BDU positive electrode 180, and a BDU negative electrode 190.

[0040] The drive motor connector can be a front drive connector 170 or a rear drive connector 140 of the vehicle. The load negative electrode 121 is electrically connected to the negative electrodes of the front drive connector 170 and the drive connector 140. The load positive electrode 124 is electrically connected to the positive electrodes of the front drive connector 170 and the rear drive connector 140. The fast charging positive electrode 123 is electrically connected to the positive electrode of the fast charging connector 160. The fast charging negative electrode 122 is electrically connected to the negative electrode of the fast charging connector 160. The BDU positive electrode 180 and the BDU negative electrode 190 are respectively connected to the positive and negative electrodes of the battery pack.

[0041] In this embodiment, the electrical connection can be a high-voltage copper bar and / or a high-voltage wire harness.

[0042] The voltage boosting module of this embodiment is used in the reverse voltage boosting fast charging scenario of the vehicle. Reverse voltage boosting fast charging means that the voltage input by the charging pile is boosted by the motor coil of the front drive or rear drive of the vehicle, and then the battery pack 100 is charged by the boosted voltage. Reverse voltage boosting can realize the reuse of the front drive or rear drive motor of the vehicle, and does not need to separately configure a voltage boosting device, which can reduce the cost, reduce the weight of the vehicle body, and improve the endurance of the vehicle.

[0043] In some embodiments, the voltage boosting module can be assembled inside the battery pack 100 and arranged inside or outside the high-voltage distribution box body. The front drive connector 170 or the rear drive connector 140 is provided with a voltage boosting interface. The fast charging connector 160 is electrically connected to the coil of the front drive motor or the rear drive motor of the vehicle through the voltage boosting interface, and then the voltage boosting is realized through the front drive motor or the rear drive motor.

[0044] In this embodiment, the voltage boosting module electrically connects the fast charging connector 160, the motor of the front drive or rear drive of the vehicle, and the battery pack 100, and then forms a reverse voltage boosting charging loop. The voltage input by the charging pile is boosted by the motor of the front drive or rear drive of the vehicle, and the voltage is higher than the voltage of the battery pack 100. Therefore, the battery pack 100 can be charged. Therefore, in the scenario where the maximum output voltage of the charging pile is less than the voltage of the battery pack, the vehicle can also be normally charged.

[0045] In this embodiment, the voltage boosting module is non-integrated with respect to the power distribution structure. Non-integrated means that it can be separated from the power distribution structure. After the power distribution structure is separated, it will not affect the non-voltage boosting circuit structure of the power distribution structure. When the voltage boosting module is assembled in the battery pack 100, it can be independently arranged with the high-voltage distribution box assembly of the battery pack 100. The voltage boosting module is not integrated with the high-voltage distribution box, but is detachable with respect to the high-voltage distribution box. When the voltage boosting module is removed, it will not affect the original function of the high-voltage distribution box.

[0046] It is worth mentioning that the application does not limit the assembly position of the boost module, and in other embodiments, the boost module can also be assembled outside the battery pack 100, for example, it can be assembled in a high-voltage distribution box, a motor controller, a high-voltage three-in-one (integration of motor controller, on-board charger, and DC / DC device) device, or a drive three-in-one (integration of drive motor, reduction box, and inverter) device outside the battery pack 100.

[0047] In this embodiment, the connector module includes an OBC (on-board charger) connector, a front drive connector 170, a rear drive connector 140, a low-voltage connector 150, and a fast charging connector 160. The OBC connector 130 is used to connect with the on-board charger, the front drive connector 170 is used to connect with the front wheel drive motor of the vehicle, the rear drive connector 140 is used to connect with the rear wheel drive motor of the vehicle, the low-voltage connector 150 is used to connect with the low-voltage control circuit of the vehicle or the battery pack 100, and the fast charging connector 160 is used to connect with the external charging pile.

[0048] In some embodiments, the boost module includes a plurality of conductive parts and a plurality of contactors, which are electrically connected with the fast charging connector and the drive motor connector, and can form a reverse boost charging circuit for charging the battery pack 100; wherein at least part of the number of conductive parts and contactors are arranged inside the high-voltage distribution box. After such arrangement, the installation and removal of the boost module will not affect the internal space of the high-voltage distribution box, which can improve the space utilization rate of the high-voltage distribution box and enable the high-voltage distribution box to be platformized and shared with different vehicles.

[0049] In some embodiments, the boost module includes a boost contactor 161 connected between the fast charging connector 160 and the rear drive connector 140 and arranged outside the high-voltage distribution box; the boost contactor 161 can conduct or cut off the electrical connection between the fast charging connector 160 and the rear drive connector 140.

[0050] The power distribution structure of the embodiment further includes a voltage stabilizing capacitor 111 connected in parallel between the positive electrode and the negative electrode of the battery pack 100, and one end of the voltage stabilizing capacitor 111 is connected in series with a voltage stabilizing contactor 115; wherein the voltage stabilizing capacitor 111 and the voltage stabilizing contactor 115 are arranged inside or outside the high-voltage distribution box. The voltage stabilizing capacitor 111 can make the elevated voltage more stable, thereby improving the voltage stability during high-voltage charging of the battery pack 100.

[0051] Continuing to refer to Figure 1In some embodiments, the voltage stabilizing capacitor 111 and the voltage stabilizing contactor 115 are arranged outside the high-voltage distribution box; the voltage boosting module comprises a first conductive member, a second conductive member 162 and a third conductive member 113; the positive pole of the fast charging connector 160 is connected to the voltage boosting contactor 161 through the first conductive member, one end of the voltage stabilizing capacitor 111 is connected to the voltage boosting contactor 161 through the second conductive member 162, the other end of the voltage stabilizing capacitor 111 is connected to one end of the voltage stabilizing contactor 115 through the third conductive member, and the other end of the voltage stabilizing contactor 115 is connected to the negative pole 190 of the BDU through the fourth conductive member 113.

[0052] It can be understood that the position of each component of the voltage boosting module is not limited in the embodiments, for example, in some embodiments, the conductive member and / or the contactor can also be arranged between the inside and the outside of the high-voltage distribution box.

[0053] In the embodiments, the first conductive member (not shown), the second conductive member 162 and the third conductive member can be high-voltage copper bars or high-voltage wire harnesses. The high-voltage copper bars can be installed in the battery pack 100 through screws at predetermined positions. In this way, the surface of each high-voltage copper bar can be provided with an insulating material, so as to avoid short circuit and improve the safety of the battery pack 100.

[0054] In the embodiments, when the voltage stabilizing capacitor 111 and the voltage stabilizing contactor 115 are arranged outside the high-voltage distribution box, the volume of the high-voltage distribution box can be reduced, on the one hand, the space utilization rate in the high-voltage distribution box can be improved, and on the other hand, the space outside the high-voltage distribution box can be utilized, thereby improving the overall space utilization rate in the battery pack 100.

[0055] In the embodiments, when the voltage boosting function is not needed, the voltage boosting module can not be installed, for example, the contactors, the conductive members and other components used to constitute the voltage boosting module can not be installed, and when the voltage boosting function is needed, the voltage boosting module can be added.

[0056] Referring to Figure 2 and Figure 3 In some embodiments, the voltage stabilizing capacitor 111 and the voltage stabilizing contactor 115 are arranged inside the high-voltage distribution box; the voltage boosting module comprises a fourth conductive member and a fifth conductive member; the positive pole 123 of the fast charging connector of the DBU is connected to one end of the voltage stabilizing capacitor 111 through the fourth conductive member 112, the other end of the voltage stabilizing capacitor 111 is connected to one end of the voltage stabilizing contactor 115 through the fifth conductive member 116, and the other end of the voltage stabilizing contactor 115 is connected to the negative pole 190 of the BDU. In the embodiments, when the space outside the high-voltage distribution box is relatively compact, the voltage stabilizing capacitor 111 and the voltage stabilizing contactor 115 can be installed in the high-voltage distribution box, thereby enabling the voltage boosting module of the application to be arranged according to the space structure at different positions in the battery pack 100.

[0057] In some embodiments, the voltage boosting module further comprises a filter assembly installed at the at least one connector and / or contactor, the filter assembly having a filtering effect and being capable of more effectively suppressing EMC (ElectroMagnetic Compatibility) problems occurring in the voltage boosting process.

[0058] In some embodiments, the filter assembly comprises a plurality of filter elements, which can be arranged on the side away from the plug-in interface of the fast charging connector and the driving motor connector, so as to make full use of the space in the battery pack 100 and facilitate the installation of the filter elements.

[0059] Figure 4 FIG. 6 is a schematic diagram of the installation structure of the filter assembly of the power distribution structure shown in the embodiments of the present application, Figure 4 FIG. 7 shows the structure of the reverse side of the connector module.

[0060] Referring to FIG. 6, Figure 4 The filter assembly comprises a first filter element 151, a second filter element 144, a third filter element 145, a fourth filter element 163, a fifth filter element 164, and a sixth filter element 165. The first filter element 151 is installed at the positive electrode of the fast charging connector, the second filter element 144 is installed at the rear driving connector 140, the third filter element 145 is installed at the voltage boosting interface, the fourth filter element 163 is installed at the fast charging connector 160, the fifth filter element 164 is installed at the negative electrode of the fast charging connector 160, and the sixth filter element 165 is installed at the voltage boosting contactor 161. The second filter element 144 and the fourth filter element 163 can be magnetic rings sleeved on the respective corresponding connectors, and the first, third, fifth, and sixth filter elements can be capacitors connected in parallel across the respective interfaces or connectors. In this embodiment, the magnetic rings can be sleeved on the front driving connector 170 or the rear driving connector 140. Since the voltage boosting interface is integrated in the front driving connector 170 or the rear driving connector 140, the magnetic rings can have a smaller volume and a larger inductance, thereby more effectively improving the EMC suppression effect.

[0061] The scheme of this embodiment integrates the voltage boosting interface 143 and the front driving connector 170 or the rear driving connector 140 into one 3pin connector, which makes the assembly of the voltage boosting module more convenient and simplifies the structure of the battery pack 100.

[0062] The scheme provided by the embodiment can reduce the volume of the high-voltage distribution box, reduce the cost, and save the arrangement space of the battery pack 100. In addition, since the high-voltage distribution box and the boost module are independently arranged, the high-voltage distribution box and the boost module can also be shared with other vehicle platforms, thereby effectively reducing the development cycle and development cost of the vehicle.

[0063] The power distribution structure of the embodiment is introduced above, and accordingly, the application also provides a battery pack 100, which is provided with the power distribution structure as described in the above embodiment.

[0064] The battery pack 100 is provided with a BDU module 110 and a connector module electrically connected with the BDU module 110, and the connector module at least includes a fast charging connector 160 and a driving motor connector. The power distribution structure includes a boost module, the boost module is arranged independently of the power distribution structure, and the boost module is electrically connected with the fast charging connector 160, the driving motor connector and the BDU module to form a reverse boost charging circuit for charging the battery pack 100. When the boost function is needed, the boost module can be assembled on the vehicle, and the battery pack 100 can be charged through the reverse boost charging circuit. When the boost function is not needed, the boost module does not need to be assembled, so that the battery pack of the application can meet the needs of different schemes, improve the standardization degree of the power distribution structure, and facilitate the platformization of different vehicle models.

[0065] Accordingly, the application also provides a vehicle, which includes the above battery pack, and the structure of the battery pack is described in the above embodiment, which will not be described here.
