The disclosure will now be discussed with reference to several exemplary embodiments. It should be understood that these embodiments are discussed only to enable those of ordinary skill in the art to better understand and thus practice the present disclosure, and are not meant to imply any limitation on the scope of the present disclosure.
As used herein, the term "comprising" and variants thereof are to be interpreted as meaning "including but not limited to" open-ended terms. The term "based on" is to be interpreted as "based at least in part on". The terms "one embodiment" and "an embodiment" are to be interpreted as "at least one embodiment.

The embodiment discloses a new energy vehicle charging and changing control method, as shown in fig. 1, which may include:
step S11, based on the electricity demand of the charging and exchanging station 40 and/or the electricity consumption unit 50, the utility supply unit 10 supplies electric energy through the regional power supply unit 30;
step S12, based on the electricity demand of the charging and exchanging station 40 and/or the electricity consumption unit 50, the auxiliary electricity supply unit 20 supplies electric energy through the regional electricity supply unit 30;
step S13, the charging and replacing station 40 provides electric energy to the new energy vehicle based on the electricity demand of the new energy vehicle;
step S14, based on the abnormal power supply of the utility power supply unit 10 and the auxiliary power supply unit 20, the charging and exchanging station 40 supplies electric energy to the first electric device 51 of the electric power utilization unit 50; wherein the first electrical device 51 comprises a device that needs to provide uninterrupted power.
In some specific vehicle operating areas (such as logistics companies, wharfs, ports, etc.), logistics transportation needs are large. Because of low operating cost of new energy vehicles, most of the new energy vehicles can select electric energy driven transport vehicles for cargo transportation. To power these electrically powered vehicles, a charging and swapping station 40 is typically built in this area. The charging and discharging station 40 may include a charging and discharging machine 41, a battery box 42, and a robot 43. The charge/discharge machine 41 can charge or discharge the battery box 42. The battery change robot 43 can exchange the battery change box 42 with a battery box on the transport vehicle. The battery box in the charging station 40 may be charged by electric energy supplied by the national grid system (i.e. the utility power supply). In addition, due to the continuous development and perfection of new energy technologies such as wind power generation and solar power generation in recent years, in order to reduce the power supply cost, energy conservation and emission reduction, a manager in a specific vehicle operation area can supply power as the auxiliary power supply part 20 to supplement the deficiency and the disadvantage of the mains supply.
In this embodiment, in order to solve the problem that multiple power supply modes in a specific vehicle operation area reasonably supply power, ensure that electric equipment and new energy vehicles in the area can normally operate, and achieve the purposes of reducing cost, saving energy and reducing emission, as shown in fig. 1, a new energy vehicle charging and power conversion control method is provided, and the method can include steps S11-S14. The above steps will be described in detail below:
in step S11, the power supply method for the specific vehicle operation area may include the utility power supply unit 10. The utility power supply unit 10 (i.e., the national power grid) has the advantages of wide distribution, stable power supply, large capacity, and the like, and is widely used. The specific vehicle operation area may include an area power supply unit 30, a charging and exchanging station 40, and a power consumption unit 50. The utility power supply unit may be electrically connected to the area power supply unit 30 of a specific vehicle operation area. The regional power supply unit 30 controls and manages the use of electric energy by the charging and discharging station 40 and the power consumption unit 50 in the specific power consumption region.
In step S12, the power supply system of the specific vehicle operation area may further include an auxiliary power supply unit 20 (including, but not limited to, a wind power generation power supply unit and a solar power generation power supply unit). The auxiliary power supply unit 20 is a clean energy source supported by the state because it does not generate harmful gas or harmful substances, and the cost of supplying electric energy to the auxiliary power supply unit 20 is low, so that it is widely used at present. The auxiliary power supply unit 20 may be electrically connected to the area power supply unit 30 in a specific vehicle operation area, and the area power supply unit 30 may control and manage the charging/exchanging station 40 and other power supply units 50 that need power supply in the specific power supply area. The auxiliary power supply unit 20 supplies electric power as a supplementary power supply device in the specific vehicle operation area, and ensures normal operation of all the power consuming units 50.
In step S13, the new energy vehicle consumes electric energy for transporting the cargo in the specific vehicle operation area. When the new energy vehicle is depleted in power consumption and needs to be replenished with power, the charging and replacing station 40 can be charged or replaced to meet the transportation requirement. When the new energy vehicle does not have a transportation task and belongs to an idle state, the new energy vehicle can be supplemented with electric energy in a charging mode; when the new energy vehicle has a transportation task and belongs to a busy state, the new energy vehicle can be supplemented with electric energy in a power exchanging mode so as to save operation time.
In step S14, since the coverage area of the utility power supply unit 10 is wide, the users are more, and most of the users use electricity in a relatively concentrated manner, the electric quantity is easily unstable at the peak of electricity consumption; meanwhile, in summer or winter, the load of the utility power supply part 10 is increased due to the large amount of use of air conditioning, electric heater, etc. due to the excessively high or excessively low air temperature. When the utility power supply unit 10 cannot bear the load, the power supply is stopped by adopting a power limiting mode; the utility power supply unit 10 also has an abnormal condition such as damage to the power supply equipment, and thus the utility power supply unit 10 cannot supply power normally. In addition, the wind power generation and supply unit may not be able to supply power due to factors such as weather, season, topography, installation location, and the like. Solar power generation and supply units are limited by natural conditions such as day and night, seasons, geographical latitude and altitude, and are affected by weather factors such as sunny, cloudy and rainy days, and sometimes cannot supply power. The auxiliary power supply unit 20 also has an abnormal condition in which power cannot be supplied. The electric power consuming part 50 of a specific vehicle operation region may include an important electric power consuming device (i.e., the first electric power consuming device 51). The first electrical device 51 may comprise a control device, a temperature control device, a network server. There are serious consequences and significant economic losses when the first electrical device 51 is powered down. When the supply of power is abnormal in both the utility power supply part 10 and the auxiliary power supply part 20, the specific power utilization area can start the power stored by the charging and exchanging station 40 to supply power to the first power devices 51, so that the first power devices 51 can be ensured to normally operate without causing significant loss.
In some embodiments, as shown in fig. 2, the new energy vehicle charging and changing control method further includes:
in step S121, the charging station 40 and/or the power consuming unit 50 first uses the auxiliary power supply unit 20 to supply electric power, based on the normal supply of the auxiliary power supply unit 20 and the normal supply of the utility power supply unit 10.
In this embodiment, as shown in fig. 2, the new energy vehicle charging and changing control method may further include step S121. In step S121, when the wind is large and/or the sunlight is sufficient, the wind power generation device and/or the solar power generation device (i.e., the auxiliary power supply 20) can supply stable electric power in the specific vehicle operation area. At the same time, the utility power supply 10 in the specific vehicle operation area is normal, and can provide sufficient and stable electric energy. The manager in the specific vehicle operation area can preferentially select the auxiliary power unit 20 to supply electric power to the charging station 40 and/or the power consuming unit 50 therein. Thus, the electric energy generated by the auxiliary power supply part 20 can be fully utilized, and the electricity cost is reduced, thereby achieving the purposes of energy conservation and emission reduction.
In some embodiments, as shown in fig. 2, the new energy vehicle charging and changing control method further includes:
step S122, based on the auxiliary power supply unit 20 supplying electric energy greater than the electric energy required by the electric power consumption unit 50, the battery-change box 42 and/or the backup battery box 44 of the charging and changing station 40 stores the auxiliary power supply unit 20 supplying electric energy; or, the charging and exchanging station 40 sends out an active charging and exchanging electric signal to the new energy vehicle.
In this embodiment, as shown in fig. 2, the new energy vehicle charging and changing control method may further include step S122. In step S122, when the wind power is large and/or the sunlight is sufficient, the electric energy provided by the auxiliary power supply unit 20 in the specific vehicle operation area is greater than the electric energy required by all the electric power consumption units 50 in the area, and the electric power generated by the auxiliary power supply unit 20 cannot be consumed by the electric power consumption units 50 in the area, and when the electric energy generated by the auxiliary power supply unit 20 is surplus, the electric energy provided by the auxiliary power supply unit 20 can be stored in the battery box 42 and/or the spare battery box 44 of the charging and replacing station 40 (in order to improve the operation capability of the new energy vehicle in the specific vehicle operation area, to improve the charging and replacing efficiency, to store more electric energy, and to provide the spare battery box 44 in the charging and replacing station 40 in addition to the battery box 42). When there is a demand for electricity from the electricity consuming portion 50, the electrical energy stored in the battery compartment 42 and/or the backup battery compartment 44 may be used.
When the battery box 42 is full, the auxiliary power supply unit 20 can continue to supply electric energy, so as to charge the spare battery box 44 and store the electric energy in the spare battery box 44, thereby avoiding electric energy waste. The auxiliary power supply unit 20 may also charge the new energy vehicles in the specific vehicle operating area, and the charging and replacing station 40 actively sends a charging and replacing electrical signal to the new energy vehicles in the specific vehicle operating area, and after receiving the signal, the new energy vehicles flexibly select charging or replacing time according to their own needs and in combination with transportation tasks and busy/idle degrees. When the new energy vehicle has a part of its battery power consumption for battery replacement and the transportation task is not urgent, the new energy vehicle can be started to charge or replace the battery in the charging and replacing station 40. The electric energy generated by the auxiliary power supply unit 20 is fully utilized, and the functions of the battery replacement box 42 and the standby battery box 44 are fully exerted, so that the electricity consumption cost and the operation cost are reduced.
In some embodiments, as shown in fig. 2, the new energy vehicle charging and changing control method further includes:
in step S123, the charging station 40 and/or the power consuming unit 50 supplies electric power using the auxiliary power supply unit 20 and the utility power supply unit 10 based on the normal supply of the auxiliary power supply unit 20 and the utility power supply unit 10.
In this embodiment, as shown in fig. 2, the new energy vehicle charging and changing control method may further include step S123. In step S123, the auxiliary power supply portion 20 can supply stable electric power when the specific vehicle is operating. At the same time, the utility power supply unit 10 in the specific vehicle operation area is all normal, and can supply stable electric energy. However, when the total electric energy required by all the electric power consuming parts 50 in the area is greater than the electric energy provided by the auxiliary power supplying part 20, and the electric energy provided by the auxiliary power supplying part 20 alone cannot meet the electric energy requirement of all the electric power consuming parts 50 in the area, the electric power supplying part 10 can be used as a supplement to provide electric energy for the electric power consuming parts 50 in the area. Such as: the auxiliary power supply unit 20 supplies electric power to the charging and exchanging station 40, and the commercial power supply unit 10 supplies electric power to the other power utilization units 50; alternatively, the auxiliary power supply unit 20 supplies electric power to the charging and exchanging station 40 and the first power device 51, and the utility power supply unit 10 supplies electric power to the other power consuming units 50 except the first power device 51. The auxiliary power supply unit 20 is matched with the commercial power supply unit 10 to supply electric energy to the power utilization units 50 in the specific vehicle operation area, so that the normal operation of all the power utilization units 50 in the area can be ensured under the condition of fully utilizing the electric energy supplied by the auxiliary power supply unit 20.
In some embodiments, as shown in fig. 2, the new energy vehicle charging and changing control method further includes:
in step S124, the battery box 42 of the charging/replacing station 40 stores the electric power supplied from the utility power supply unit 10, based on the electric power supplied from the auxiliary power supply unit 20 being smaller than the electric power required from the power consumption unit 50 and the electric power supplied from the utility power supply unit 10 being equal in electric power supply rate.
In the present embodiment, the utility power supply unit 10 divides 24 hours per day into a plurality of periods such as peak, valley, and flat in order to reduce peak electricity consumption and encourage valley electricity consumption according to the load change condition of the power grid. The peak section is a peak section with high electricity consumption, and the power grid load is high at the moment, and the electricity price is high, which is called peak electricity price; the valley section is a low valley section of electricity consumption, and the load of the power grid is small and the electricity price is low, so that the valley section is called as the valley electricity price; the flat section is a common section for electricity consumption, and at the moment, the load of the power grid is moderate, and the electricity price is centered, which is called as flat electricity price.
As shown in fig. 2, the new energy vehicle charging and changing control method may further include step S124. In step S124, when the wind power of the specific vehicle operation area is small and/or the weather is overcast, the auxiliary power supply unit 20 provides less power, and the power requirements of all the power consuming units 50 in the area cannot be satisfied. The utility power supply unit 10 is capable of supplying stable electric power and has a low electric power price. The battery box 42 of the charging/exchanging station 40 in this area stores electric power supplied from the commercial power supply unit 10. Thus, not only the low-cost clean energy provided by the auxiliary power supply unit 20 is fully utilized, but also the battery box 42 of the charging and replacing station 40 is charged when the electricity price supplied by the commercial power supply unit 10 is flat electricity price, so as to store electric energy, and the electricity cost can be reduced.
In some embodiments, as shown in fig. 2, the new energy vehicle charging and changing control method further includes:
in step S125, the battery box 42 and/or the backup battery box 44 of the charging/replacing station 40 stores the electric power supplied from the utility power supply unit 10, based on the electric power supplied from the auxiliary power supply unit 20 being smaller than the electric power required from the power consumption unit 50 and the electric power supplied from the utility power supply unit 10 being at the valley price.
In this embodiment, as shown in fig. 2, the new energy vehicle charging and changing control method may further include step S125. In step S125, when the vehicle is in the specific vehicle operation area, the auxiliary power supply unit 20 supplies less power, and the power demand of all the power consuming units 50 in the area cannot be satisfied. The utility power supply unit 10 is capable of supplying stable electric energy, and the electricity price is the electricity valley price. In order to fully utilize the period in which the utility power supply unit 10 charges the electricity supply battery box 42 of the charging and exchanging station 40 in the area, the utility power supply unit 10 may charge the spare battery box 44 of the charging and exchanging station 40 in the area at the same time; or any one of the battery replacement box 42 and the backup battery box 44 is charged, thereby greatly reducing the electricity costs.
In some embodiments, as shown in fig. 2, the new energy vehicle charging and changing control method further includes:
step S15, based on the activation of the first electric device 51, the second electric device 52, and the third electric device 53, the utility supply section 10, the auxiliary power supply section 20, and the charging station 40 supply electric power to the electric power consumption section 50; wherein the second power utilization device 52 comprises a high load power utilization device; the third electric device 53 comprises a low load electric device.
In the present embodiment, the first electric device 51 is a device that is important in the specific vehicle operation area and cannot be powered off for 24 hours, such as a control device, a temperature control device, a network server, and the like. There are serious consequences and significant economic losses when the first electrical device 51 is powered down.

The third electric device 53 is a low-load electric device such as a daily lighting device of a port or dock in the specific vehicle operation area. As shown in fig. 2, the new energy vehicle charging and changing control method may further include step S15. In step S15, in the specific vehicle operation area, when the electric power required by the first electric device 51, the second electric device 52 and the third electric device 53 is larger than the total capacity of the voltage transformation equipment for supplying electric power to the utility power supply unit 10 and the auxiliary power supply unit 20, and the electric power of the battery box 42 and the spare battery box 44 in the charging and replacing station 40 is sufficient, the charging and replacing station 40 can be started to supply electric power to fill the electric energy gap when charging is not needed. The utility power supply unit 10 may supply power to the second power utilization device 52, the auxiliary power supply unit 20 may supply power to the third power utilization device 53, and the charging and exchanging station 40 may supply power to the first power utilization device 51.

In this way, the high-capacity electric energy requirement of three electric devices in simultaneous working can be met by setting the smaller-capacity voltage transformation equipment, so that the cost of the voltage transformation equipment of the commercial power supply part 10 and the auxiliary power supply part 20 is reduced. In other embodiments, in the specific vehicle operation area, when the electric power required by the first electric device 51, the second electric device 52, the third electric device 53, and the charging/replacing station 40 is larger than the total capacity of the voltage transformation device for supplying electric power to the utility power supply unit 10 and the auxiliary power supply unit 20, the manager of the specific vehicle operation area may reduce the number of battery boxes charged simultaneously in the replacing station, and charge the battery boxes 42 and/or the spare battery boxes 44 on the basis of the principle of first-in-first charging (first-in-first charging of the battery boxes and then-charging of the battery boxes); the battery compartment 42 and/or the battery compartment 44 may also be charged in a slow-charging manner (i.e., with reduced charging current) to meet the power requirements of the particular vehicle operating region and ensure stable and safe operation of the power consuming portions 50. Thus, the high-capacity electric energy requirement of the four electric devices during simultaneous operation can be met by arranging the smaller-capacity voltage transformation equipment, and the cost of the voltage transformation equipment of the commercial power supply part 10 and the auxiliary power supply part 20 is reduced.
