The vehicle power supply 141 is in transmission connection with the traveling assembly 13 through a driving motor 143. The electric vehicle 100 can be connected to the charging pile 200, and charges the entire vehicle power supply 141 through the charging pile 200.

The discharging conversion module 1422 is configured to invert the dc power output by the vehicle power supply 141 and transmit the inverted dc power to the external electric device 300, so as to drive the electric device 300 to work. Specifically, the charging conversion module 1421 and the discharging conversion module 1422 are integrally disposed on the first circuit board 1423 and are connected by copper traces on the first circuit board 1423. The charging conversion module 1421 and the discharging conversion module 1422 are both connected to the entire vehicle power supply 141 through a copper wire on the first circuit board 1423.
Further, besides the discharge conversion module 1422 being connected to the entire vehicle power supply 141, the discharge conversion module 1422 can also be connected to the electric device 300 through a copper wire on the first circuit board 1423. The electric device 300 may be a household appliance or a digital product with a built-in discharge resistor. It can be understood that, in the case that the powered device 300 is low in power or the powered device 300 needs to be driven by an external power source to operate, the ac power source required for the operation can be provided for the powered device 300 through the discharging conversion module 1422.
Further, in addition to the charging conversion module 1421 being connected to the entire vehicle power supply 141, the charging conversion module 1421 is also connected to the charging interface 15 through a copper plate wire on the first circuit board 1423. So that the charging pile 200 can be connected to the charging conversion module 1421 through the charging interface 15, thereby realizing the conversion between the ac power and the dc power.
Through the arrangement, the integration degree of each component in the power supply distributor 142 is improved, and the wiring harness arrangement in the power supply distributor 142 is optimized, so that the space layout in the power supply distributor 142 is more attractive and compact. Therefore, the size of the power supply distributor 142 is reduced, and the light weight of the whole vehicle is realized.
As shown in fig. 3, as an implementation manner, a discharge interface 16 for connecting the electric device 300 is further disposed on the electric vehicle 100, and the discharge interface 16 is connected to the first circuit board 1423 through a wire harness or a copper bar.

Further, a preset threshold is provided in the first control module 1424, the electric device 300 is connected to the entire vehicle power supply 141 through the discharge conversion module 1422, and when the remaining power of the entire vehicle power supply 141 is greater than or equal to the preset threshold, the first control module 1424 controls the entire vehicle power supply 141 to perform a discharge operation, so as to supply power to the electric device 300. As can be appreciated, when the remaining capacity of the vehicle power supply 141 is less than the preset threshold, the first control module 1424 controls the vehicle power supply 141 to stop the discharging operation. Thereby promoted the degree of integrating of each part in power supply distributor 142, reduced power supply distributor 142's volume, realized the lightweight of whole car.
In addition, when the charging pile 200 is connected to the entire vehicle power supply 141 through the charging conversion module 1421, the first control module 1424 is configured to control a charging process of the entire vehicle power supply 141. That is, in the case that the entire vehicle power supply 141 completes charging, the first control module 1424 can disconnect the connection between the charging conversion module 1421 and the charging pile 200.
As shown in fig. 4, as an implementation manner, the electric vehicle 100 further includes a first load 17, the power distributor 142 further includes a voltage transformation module 1425, the first load 17 is connected to the entire vehicle power supply 141 through the voltage transformation module 1425, and the voltage transformation module 1425 modulates the voltage output by the entire vehicle power supply 141 and transmits the modulated voltage to the first load 17. Specifically, the operating voltage of the first load 17 is smaller than the output voltage of the entire vehicle power supply 141. The output voltage of the entire vehicle power supply 141 is stepped down by the voltage transforming module 1425 and then transmitted to the first load 17. Thereby protecting the first load 17 from damage to the first load 17. The first load 17 may be a vehicle-mounted electrical device driven by low voltage, such as a vehicle-mounted computer, a vehicle-mounted audio device, or a lighting system.
Further, the transformer module 1425 is integrally disposed on the first circuit board 1423, and the transformer module 1425, the charge conversion module 1421 and the discharge conversion module 1422 are connected by copper wires on the first circuit board 1423. Thereby promoted the degree of integrating of each part in power supply distributor 142, reduced power supply distributor 142's volume, realized the lightweight of whole car.
As shown in fig. 4, as an implementation manner, the power distributor 142 further includes a second control module 1426, the second control module 1426 is integrally disposed on the first circuit board 1423, and the second control module 1426 is connected to the transformer module 1425 through a copper wire on the first circuit board 1423. Specifically, the second control module 1426 may be configured as a DSP control chip, so as to control the transforming operation of the transforming module 1425 on the entire vehicle power supply 141. Thereby promoted the degree of integrating of each part in power supply distributor 142, reduced power supply distributor 142's volume, realized the lightweight of whole car.
It can be understood that the charging conversion module 1421, the discharging conversion module 1422, the voltage transformation module 1425, the first control module 1424, and the second control module 1426 are all integrated on the first circuit board 1423, and the charging conversion module 1421, the discharging conversion module 1422, and the first control module 1424 are connected by a copper wire on the first circuit board 1423 to form a charging and discharging module; the transformer module 1425 and the second control module 1426 are connected by copper wires on the first circuit board 1423, and form a transformer module. Wherein the transformer module and the charging/discharging module are connected by a copper wire on the first circuit board 1423. Through the arrangement, the integration effect of the power supply distributor 142 is improved, the size of the power supply distributor 142 is reduced, and the light weight of the whole vehicle is realized.
As shown in fig. 5, as another implementation manner, the transformer module 1425 and the second control module 1426 are both integrally disposed on the second circuit board 1427 and electrically connected through a copper board on the second circuit board 1427. The first circuit board 1423 and the second circuit board 1427 are provided as separate components, and the first circuit board 1423 and the second circuit board 1427 are connected by a wire harness. Specifically, the charging and discharging module and the transformation module are connected through a wiring harness in a circuit mode. Thereby promoted power distributor 142's integrated effect, reduced power distributor 142's volume, realized the lightweight of whole car.
As an implementation manner, the voltage transformation module 1425, the charging conversion module 1421, and the discharging conversion module 1422 are connected to the vehicle power supply 141 through a power path. Compared with the related technology, the wire harness arrangement requirement in the power supply distributor 142 is reduced in the implementation mode provided by the application, so that the integration degree of component arrangement in the power supply distributor 142 is higher, and the production cost is reduced.
As shown in fig. 6, as one implementation, the electric vehicle 100 further includes a low-voltage battery 19, wherein a rated voltage of the low-voltage battery 19 is smaller than a rated voltage of the entire vehicle power supply 141. The low-voltage battery 19 is connected to the first load 17 and the transforming module 1425, and the low-voltage battery 19 is charged by the transforming module 1425. Specifically, in the case where the operating voltage of the first load 17 is insufficient, the first load 17 can be driven to operate by the entire vehicle power supply 141 and the low-voltage battery 19 in common. In addition, in the event of a failure of the entire vehicle power supply 141, the first load 17 can be driven to operate only by the low-voltage battery 19. So that the electric vehicle 100 meets the emergency requirement under the condition of the failure of the vehicle power supply 141.
As an implementation manner, the electric vehicle 100 further includes a second load 18, an operating voltage of the second load 18 is greater than an operating voltage of the first load 17, and the second load 18 is directly connected to the vehicle power supply 141.

Thereby meeting the operating voltage requirements of second load 18.
As shown in fig. 6, it can be understood that the output or input voltage of the entire vehicle power supply 141 is transformed by the power distributor 142, so as to meet the power consumption requirement of each electrical component on the electric vehicle 100. Further, the charging conversion module 1421, the discharging conversion module 1422, and the transforming module 1425 in the power distributor 142 form an integrated module 1428, so that integration of three powers of charging, discharging, and transforming is achieved, the number of components in the power distributor 142 is reduced, the production cost is reduced, and the overall volume and the required layout space of the power distributor 142 are reduced.
