The present application provides a power battery 10. The power battery 10 is used to be installed in the lower body assembly (not shown in the figure). The power battery 10 can provide driving force for the operation of the vehicle. The power battery 10 includes a battery housing 11. The battery housing 11 is formed with a battery cavity 111. The battery cavity 111 includes a first end 111a and a second end 111b that are arranged opposite to each other. The second end 111b is close to the rear of the lower body assembly.

[0025] The power battery 10 includes a battery disconnect unit 13 (Battery Disconnect Unit, BDU). The battery disconnect unit 13 is disposed in the battery cavity 111, and the battery disconnect unit 13 is located on the side of the second end 111b. The battery disconnect unit 13 is used to electrically connect to the battery cell 12 in the power battery 10. The battery disconnect unit 13 is used as a distribution box, which can cut off the power battery 10 to protect the electronic equipment inside the vehicle from electric shock damage, etc. Among them, the working principle of the battery disconnect unit 13 is conventionally known to those skilled in the art and is not limited here.

[0026] The power battery 10 also includes a motor control unit 14 (MCU), a DC-DC converter 15 (DC-DC converter), an on-board charging unit 16 (OBC) and a power distribution unit 17 (PDU).

[0027] Among them, one of the motor control unit 14, the DC-DC converter 15, the on-board charging unit 16 and the power distribution unit 17 is stacked up and down with the battery disconnect unit 13. Three of the motor control unit 14, the DC-DC converter 15, the on-board charging unit 16 and the power distribution unit 17 are stacked up and down and are located on the other side of the second end 111b. That is, one of the motor control unit 14, the DC-DC converter 15, the on-board charging unit 16 and the power distribution unit 17 is stacked up and down with the battery disconnect unit 13 and is located on one side of the second end 111b, and the remaining three of the four are stacked up and down and are located on the other side of the second end 111b.

[0028] The motor control unit 14, the DC-DC converter 15, the on-board charging unit 16 and the power distribution unit 17 have at least the following four settings in the battery housing 11. The first setting is as follows. The motor control unit 14 and the battery circuit breaker unit 13 are stacked up and down on one side of the second end 111b. The DC-DC converter 15, the on-board charging unit 16 and the power distribution unit 17 are stacked on each other on the other side of the second end 111b. Among them, the specific up and down position relationship between the motor control unit 14 and the battery circuit breaker unit 13, and the specific up and down position relationship between the DC-DC converter 15, the on-board charging unit 16 and the power distribution unit 17 can be determined according to actual needs.

[0029] The second configuration is as follows. The DC-DC converter 15 and the battery circuit breaker unit 13 are stacked up and down on one side of the second end 111b. The motor control unit 14, the on-board charging unit 16 and the power distribution unit 17 are stacked up and down on the other side of the second end 111b. The specific up-and-down position relationship between the DC-DC converter 15 and the battery circuit breaker unit 13, and the specific up-and-down position relationship between the motor control unit 14, the on-board charging unit 16 and the power distribution unit 17 can be determined according to actual needs.

[0030] The third setting method is as follows. The on-board charging unit 16 and the battery circuit breaker unit 13 are stacked up and down on one side of the second end 111b. The motor control unit 14, the DC-DC converter 15 and the power distribution unit 17 are stacked on each other on the other side of the second end 111b. Among them, the upper and lower position relationship between the on-board charging unit 16 and the battery circuit breaker unit 13, and the specific upper and lower position relationship between the motor control unit 14, the DC-DC converter 15 and the power distribution unit 17 can be determined according to actual needs.

[0031] The fourth setting method is as follows. The power distribution unit 17 and the battery disconnect unit 13 are stacked up and down on one side of the second end 111b. The motor control unit 14, the DC-DC converter 15 and the vehicle charging unit 16 are stacked on each other on the other side of the second end 111b. Among them, the upper and lower position relationship between the power distribution unit 17 and the battery disconnect unit 13, and the specific upper and lower position relationship between the motor control unit 14, the DC-DC converter 15 and the vehicle charging unit 16 can be determined according to actual needs.

[0032] Therefore, while the power demand is met by the power battery 10, the space at the second end 111b of the power battery 10 is utilized to integrate the motor control unit 14, the DC-DC converter 15, the on-board charging unit 16 and the power distribution unit 17 at the second end 111b of the power battery 10, so as to realize two-in-one on one side of the second end 111b and three-in-one on the other side of the second end 111b, thereby lowering the floor height and increasing the luggage compartment space and the rear human-machine space at the same time, thereby improving the user experience.

[0033] Please continue reading Figures 1 to 3 , in order to elaborate on at least four configurations of the motor control unit 14, the DC-DC converter 15, the on-board charging unit 16 and the power distribution unit 17, the fourth configuration will be described in detail below. The fourth configuration: the power distribution unit 17 and the battery circuit breaker unit 13 are stacked, and the motor control unit 14, the DC-DC converter 15 and the on-board charging unit 16 are stacked with each other. That is, the power distribution unit 17 is arranged in the battery cavity 111 with the battery circuit breaker unit 13 and is located on one side of the second end 111b. The motor control unit 14, the DC-DC converter 15 and the on-board charging unit 16 are arranged in the battery cavity 111 and are located on the other side of the second end 111b. Through the above configuration, the floor height is lowered, and the luggage compartment space and the rear man-machine space are simultaneously increased, thereby improving the user experience.

[0034] In a specific embodiment, the battery disconnect unit 13 is connected to the bottom of the inner side of the battery housing 11, and the power distribution unit 17 is located above the battery disconnect unit 13. Alternatively, the power distribution unit 17 is connected to the bottom of the inner side of the battery housing 11, and the battery disconnect unit 13 is located above the power distribution unit 17. The motor battery disconnect unit 13 and the motor control unit 14 are detachably connected or fixedly connected, so that the structural connection between the battery disconnect unit 13 and the power distribution unit 17 is more stable, reducing shaking, etc.

[0035] In addition, the motor control unit 14, the DC-DC converter 15 and the on-board charging unit 16 are three-in-one, and there are six arrangements of the positions of the motor control unit 14, the DC-DC converter 15 and the on-board charging unit 16 stacked on each other. The first arrangement: the motor control unit 14, the DC-DC converter 15 and the on-board charging unit 16. The second arrangement: the motor control unit 14, the on-board charging unit 16 and the DC-DC converter 15. The third arrangement: the DC-DC converter 15, the motor control unit 14 and the on-board charging unit 16. The fourth arrangement: the DC-DC converter 15, the on-board charging unit 16 and the motor control unit 14. The fifth arrangement: the on-board charging unit 16, the motor control unit 14 and the DC-DC converter 15. The sixth arrangement: the on-board charging unit 16, the DC-DC converter 15 and the motor control unit 14. When the motor control unit 14 , the DC-DC converter 15 and the onboard charging unit 16 are stacked, the three can be detachably connected or fixedly connected, so that the connection between the motor control unit 14 , the DC-DC converter 15 and the onboard charging unit 16 is more stable and reduces shaking.

[0036] Similarly, the first, second and third arrangements of the motor control unit 14, DC-DC converter 15, on-board charging unit 16 and power distribution unit 17 in the battery housing 11 can be arranged similarly to the fourth arrangement, and will not be described in detail here.

[0037] In some embodiments, the DC-DC converter 15 and the on-board charging unit 16 are integrated to form an integrated power supply on-board charging assembly (not shown in the figure). Through the above-mentioned two-in-one integration of the DC-DC converter 15 and the on-board charging unit 16, the number of packaging shells can be reduced and the production cost can be reduced; at the same time, the internal size of the battery shell 11 occupied by the DC-DC converter 15 and the on-board charging unit 16 can be reduced, thereby meeting the installation requirements of other motor control units 14 and power distribution units 17.

[0038] In addition, the motor control unit 14 is located above the integrated power vehicle charging assembly. Since the integrated power vehicle charging assembly has at least one packaging shell, the packaging shell can play a certain supporting role for the motor control unit 14. When the motor control unit 14 is arranged in the battery shell 11, the battery shell 11 can play a protective role. At this time, the motor control unit 14 can reduce its packaging shell, reduce production costs, etc.

[0039] In some embodiments, the battery disconnect unit 13 is integrated with the power distribution unit 17. Through the above-mentioned two-in-one integration of the battery disconnect unit 13 and the power distribution unit 17, the number of packaging shells can be reduced, and the production cost can be reduced; at the same time, the internal size of the battery shell 11 occupied by the battery disconnect unit 13 and the power distribution unit 17 can be reduced, so as to meet the installation requirements of other structures.

[0040] In some embodiments, the power battery 10 further includes a refrigeration assembly (not shown in the figure). The refrigeration assembly is arranged between the integrated power vehicle charging assembly and the motor control unit 14. The refrigeration assembly has a refrigeration function, which can dissipate heat from the integrated power vehicle charging assembly and the motor control unit 14, reduce damage to the integrated power vehicle charging assembly and the motor control unit 14, and thus increase the service life of the integrated power vehicle charging assembly and the motor control unit 14.

[0041] The above-mentioned refrigeration component can be water-cooled, air-cooled, etc. In a specific embodiment, the refrigeration component includes a water-cooled plate 18. The orthographic projections of the integrated power supply vehicle charging assembly and the motor control unit 14 on the water-cooled plate 18 are both located inside the water-cooled plate 18. Through the above-mentioned projection area and other limitations, the contact area between the water-cooled plate 18 and the integrated power supply vehicle charging assembly and the motor control unit 14 is increased respectively, thereby improving the heat dissipation effect and heat dissipation efficiency of the integrated power supply vehicle charging assembly and the motor control unit 14. The above-mentioned water-cooled plate 18 is a conventional structure for those skilled in the art and is not limited here.

[0042] In some embodiments, the wiring harness of the integrated power onboard charging assembly, the wiring harness of the motor control unit 14, and the wiring harness integrated with the battery disconnect unit 13 and the power distribution unit 17 are combined into an integrated wiring harness (not shown in the figure). The integrated wiring harness passes through the battery housing 11 and is connected to external components. Compared with the wiring harness being arranged outside the power battery 10, this embodiment can reduce the risk of the wiring harness being easily torn off.

[0043] The wiring harness of the above-mentioned integrated power vehicle charging assembly can be a positive wiring harness, a motor control unit 14 signal line, a battery circuit breaker unit 13 and a power distribution unit 17 integrated signal harness connected to the battery housing 11, avoiding the problem of high-voltage wiring being easily torn off.

[0044] Please continue reading Figures 1 to 3 The present application provides a vehicle. The vehicle (not shown in the figure) includes the above-mentioned power battery 10. By using the above-mentioned power battery 10, the vehicle not only reduces the floor height in the vehicle, but also increases the luggage space and the rear man-machine space in the vehicle, thereby improving the user experience; at the same time, the collision energy absorption space in the vehicle is increased, and the space is fully utilized; in addition, the design requirements of the subframe and suspension hard points are reduced, and the assembly space is increased, which is convenient for assembly and installation. For example, the Z-direction height of a rear-wheel drive vehicle is reduced by at least 80 mm.

[0045] In some embodiments, the vehicle further includes a drive motor 21. The motor control unit 14 of the power battery 10 is electrically connected to the drive motor 21. The motor control unit 14 can convert the high-voltage direct current of the power battery 10 into three-phase electricity, thereby driving the drive motor 21 connected thereto to work. When the drive motor 21 performs braking energy recovery, the three-phase electricity generated by the drive motor 21 can be converted into high-voltage direct current by the motor control unit 14, and the converted high-voltage direct current is transmitted to the power battery 10 through the power distribution unit 17, thereby charging the power battery 10 and realizing the energy recovery function.

[0046] The motor control unit 14 is connected to the drive motor 21 via a three-phase line. A portion of the three-phase line is located inside the battery housing 11 and is confined. Another portion of the three-phase line is located outside the battery housing 11 and is connected to the drive motor 21. Since the three-phase line is at least partially confined inside the battery housing 11, the risk of the three-phase line being torn off can be reduced. In addition, the motor control unit 14 is connected to one end of the resolver line, the resolver line passes through the battery housing 11, and the motor control unit 14 is connected to the other end of the resolver line.

[0047] Furthermore, the motor controller unit and the integrated power vehicle charging assembly are respectively connected with the drive motor 21 to achieve heat dissipation of the motor control unit 14 and the integrated power vehicle charging assembly. For example, a water pipe (not shown in the figure) is passed through the battery housing 11 and connected to the water inlet of the water cooling plate 18, and another water pipe is passed through the battery housing 11 and connected to the water outlet of the water cooling plate 18. The two water pipes and the water cooling plate 18 form a water circulation for simultaneously dissipating heat for the motor control unit 14, the integrated power vehicle charging assembly and the drive motor 21.

[0048] In some embodiments, the vehicle further includes a storage battery 22, and the integrated power supply vehicle charging assembly of the power battery 10 is electrically connected to the storage battery 22. For example, the power battery 10 can transmit high-voltage direct current to the integrated power supply vehicle charging unit 16 through the power distribution unit 17, and the integrated power supply vehicle charging unit 16 can reduce the high-voltage direct current to a low-voltage direct current of 13.8V, thereby using the reduced low-voltage direct current to charge the storage battery 22.

[0049] In some embodiments, the vehicle also includes a fast and slow charging interface 23. The power distribution unit 17 is electrically connected to the fast and slow charging interface 23. The fast and slow charging interface 23 includes but is not limited to a fast charging interface and a slow charging interface. Among them, the power distribution unit 17 can be electrically connected to an external slow charging pile through the slow charging interface. The power distribution unit 17 can be electrically connected to an external fast charging pile through the fast charging interface. One end of the fast and slow charging harness is connected to the power distribution unit 17, and is passed through the battery housing 11, and then electrically connected to the fast and slow charging interface 23.

[0050] The power distribution unit 17 can convert the 220V household AC power of the slow charging pile into DC power that matches the voltage of the power battery 10. The converted DC power is delivered to the power battery 10 through the power distribution unit 17, realizing the function of charging the power battery 10 with household AC power. The power distribution unit 17 can be connected to the external fast charging pile through the fast charging pile interface. At this time, the power distribution unit 17 can deliver the high-voltage DC power of the fast charging pile to the power battery 10, realizing the function of quickly charging the power battery 10.

[0051] In some embodiments, the vehicle further includes a compressor 24. The power distribution unit 17 is electrically connected to the compressor 24. The power distribution unit 17 can deliver high-voltage direct current from the power battery 10 to the compressor 24, thereby realizing the function of supplying power to the compressor 24 to drive the compressor 24 to work.

[0052] In addition, the vehicle may also include other devices. The other devices may be, but are not limited to, a vehicle heater (not shown in the figure). The power distribution unit 17 is electrically connected to the vehicle heater, so as to supply power to the vehicle heater to drive the vehicle heater to work.
