Embodiment two

This embodiment provides an electric vehicle power supply service system capable of implementing the method mentioned in Embodiment 1. This method can automatically plan supplementary power lines for various types of electric vehicles operating in the city so that they can be replenished in time. power to extend its battery life. As shown in FIG. 1 , an electric vehicle supplementary power service system 1 includes a plurality of electric vehicles 6 in operation and a service subsystem 2 for providing supplementary power (ie supplementary power) services for these electric vehicles 6 .

As shown in Figure 2, each electric vehicle 6 includes a battery pack 7, a battery pack power monitoring module 8, an electric vehicle positioning module 9, an electric vehicle communication module 10, an electric vehicle information notification module 15, an electric vehicle control module 11, a judgment module 13 and command input module 34 and other functional modules.

The electric vehicle control module 11 is used to control the battery pack power monitoring module 8, the electric vehicle positioning module 9, the electric vehicle communication module 10, the electric vehicle information notification module 15, the judgment module 13 and the command input module 34 and other functional modules according to certain instructions. run.

The electric vehicle communication module 10 is used to be in charge of the information exchange between various functional modules and the external information exchange under the control of the electric vehicle control module 11 .

The battery pack 7 is used to provide driving power for the electric vehicle 6 . Different types of electric vehicles 6 can be equipped with battery packs 7 with different battery capacities.

The battery pack power monitoring module 8 is used to monitor the remaining power of the battery pack 7 in the electric vehicle 6 that is running.

The judging module 13 is used for judging whether the current remaining power of the electric vehicle 6 is below the warning power. The warning electric quantity can be set as 5%～10% of the battery capacity of the battery pack 7 according to the actual situation. When the judging module 13 judges that the average value of the remaining electric quantity calculated within a period of time is below the warning electric quantity, a power shortage judgment result indicating that the electric vehicle 6 needs to be replenished is obtained, and the power shortage judgment result is passed through the electric vehicle The communication module 10 sends to the electric vehicle control module 11 , and also sends to the electric vehicle information notification module 15 through the electric vehicle communication module 10 . The purpose of counting the remaining power over a period of time is to prevent false alarms caused by occasional power measurement errors, thereby reducing the rate of false alarms and helping to maintain the orderly and efficient operation of the entire electric vehicle power supply service system 1 .

The electric vehicle positioning module 9 is used to obtain the current position of the electric vehicle 6 . When the electric vehicle control module 11 receives the power shortage judgment result, the electric vehicle positioning module 9 is controlled to obtain the current position of the electric vehicle 6, and the current position of the electric vehicle 6 and the location of the battery pack 7 are transmitted through the electric vehicle communication module 10. The remaining power and the battery pack model are sent to the service subsystem 2, so that the service subsystem 2 plans a suitable supplementary circuit for the electric vehicle 6 and selects a suitable supplementary service type.

The electric vehicle information notification module 15 is used to inform the driver of the electric vehicle 6 that the current remaining power of the battery pack 7 is insufficient, and that it needs to be replenished in time. When the electric vehicle information notification module 15 receives the power shortage judgment result, it can inform the driver of the insufficient power information in various ways such as voice broadcast, screen display, music playing or vibration, so as to let him know the power usage of the battery pack 7 Condition.

The command input module 34 is used for allowing the driver of the electric vehicle 6 to input related commands according to the information notified by the electric vehicle information notifying module 15 .

As shown in FIG. 1 , the service subsystem 2 includes a plurality of movable service vehicles 5 and a service station 3 for dispatching the service vehicles 5 to charge the electric vehicles 6 .

The service station 3 can be set up near a university or a research institute in a city, so as to obtain technical support nearby. As shown in FIG. 3 , the service station 3 includes functional modules such as a service station communication module 12 , a route planning module 14 , a storage module 31 , and a service station control module 16 .

The service station control module 16 is used to control the operation of functional modules such as the service station communication module 12 , the route planning module 14 and the storage module 31 according to certain instructions.

The service station communication module 12 is used to be responsible for the information exchange between various functional modules and the external information exchange under the control of the service station control module 16 . The service station communication module 12 can receive the remaining power and current location of the built-in battery pack 7 sent by an electric vehicle 6 and send the remaining power and current location to the route planning module 14 .

The storage module 31 stores the map of the city where the electric vehicle is located and the service range of all service vehicles 5 in the city. The map contains information on all roads in the current city.

The route planning module 14 is used to plan a supplementary circuit route for the electric vehicle to be charged and dispatch a service vehicle 5 as a supplementary service vehicle to provide supplementary service for the electric vehicle. Specifically, when the route planning module 14 receives the current position of a certain electric vehicle 6, it will mark the electric vehicle 6 as the target electric vehicle, and read the service range and target electric vehicle range of all service vehicles 5 from the storage module 31. According to the map of the city where the target electric vehicle is located, the driving range supported by its remaining power is estimated, and then the driving range is compared with the service range of all service vehicles 5, and different comparison results are obtained, and determined according to these comparison results Supplementary service vehicle. The determination process of the power supply service vehicle is as follows:

As shown in Figure 4, the dashed line represents the service range of each service vehicle 5, ◎ represents the current location of each service vehicle 5 (such as _A1 , _A2 and _A3 ), and 〇 represents the target electric vehicle (such as T) The current position of , the dotted line indicates the driving range supported by the remaining power of the target electric vehicle. When it is compared that the driving range does not intersect with the service ranges of all service vehicles 5, the route planning module 14 continues to compare the current position of the target electric vehicle with the size of the shortest road distance between the current positions of all service vehicles, and compares the distance between the current position of the target electric vehicle and the current position of the target electric vehicle. The service vehicle with the shortest distance from the nearest road is used as the power supply service vehicle. The route planning module 14 only compares the shortest road distance between the current position of the service vehicle and the current position of the target electric vehicle, and then selects the service vehicle with the smallest shortest road distance, instead of comparing the current position of the service vehicle and the current position of the target electric vehicle This fully considers the factor of the travel time of the target electric vehicle, so that the target electric vehicle can travel as short a distance as possible before recharging, so as to save the driver's time cost. The shortest road between the current position of the target electric vehicle and the current position of _any service vehicle is determined in this way: for example, in FIG. The road length of the road, the road with the smallest road length is taken as the nearest road. The length of the nearest road is the nearest road distance.

As shown in FIG. 5 , when it is compared that the driving range only intersects with the service range of a certain service vehicle, the route planning module 14 directly regards the service vehicle as the power supply service vehicle. For example, in FIG. 5 , the driving range of the target electric vehicle only intersects with the service range of service vehicle _A2 , so the route planning module 14 directly uses service vehicle _A2 as the service vehicle for supplementary power, and no longer compares other service vehicles with the target electric vehicle. The size of the shortest road distance between vehicles, even if the service vehicle _A1 is closer to the target electric vehicle. This is because each service vehicle has a pre-specified service scope. If the service is performed beyond its own service scope for emergency, it will inevitably affect the service quality of other electric vehicles.

As shown in Figure 6, when comparing the travel range and the service ranges of multiple service vehicles 5 all intersect (that is, partially overlap), the route planning module 14 continues to compare the current position of the target electric vehicle with the current position of the intersecting multiple service vehicles The size of the nearest road distance and compare the service vehicle with the shortest road distance to the current location of the target electric vehicle as the power supply service vehicle. For example, in FIG. 6 , because the shortest road distance between the service vehicle A ₁ and the target electric vehicle is the smallest, the service vehicle A ₁ is used as the power supply service vehicle.

After the route planning module 14 determines the power supply service vehicle for the target electric vehicle, it continues to determine the supplementary circuit for the target electric vehicle. As shown in FIG. 7 , the route planning module 14 continues to use the intersection of the nearest road and the driving range between the current position of the power supply service vehicle and the current position of the target electric vehicle as the power supply point S, and the intersection point S between the power supply service vehicle and the current position of the target electric vehicle. The part between the charging point S is taken as the service route L ₁ and the part between the target electric vehicle and the charging point S in the nearest road is taken as the supplementary circuit L ₂ . Then, the service station control module 16 controls the service station communication module 12 to send the supplementary circuit _L2 to the target electric vehicle. The electric vehicle information notification module 15 informs the driver of the supplementary circuit and allows him to decide whether to adopt the supplementary circuit. When the driver of the target electric vehicle adopts this supplementary circuit, the confirmation information is input by the command input module 34, and the confirmation information is sent to the service station 3 by the electric vehicle communication module 10, and the service station communication module 12 will serve after receiving the confirmation information. The route is sent to the service car 5. After seeing the service route, the driver of the service car 5 drives along the service route to the charging point, where the target electric vehicle is charged.

As shown in Figures 8 and 9, the service vehicle 5 includes a service vehicle control module 17, an energy storage battery 18, a service vehicle communication module 19, a service vehicle information notification module 20, a service vehicle positioning module 21, a solar power generation panel 22, a Robot 26 and battery pack storage warehouse 23.

The service vehicle control module 17 is used to control the operation of functional modules such as the energy storage battery 18, the service vehicle communication module 19, the service vehicle information notification module 20 and the service vehicle positioning module 21 according to certain instructions.

The service vehicle communication module 19 is used to be responsible for the information exchange between various functional modules and the external information exchange under the control of the service vehicle control module 17 .

The energy storage battery 18 not only provides driving power for the service vehicle 5 itself, but also quickly charges the battery packs of various target electric vehicles through the electric vehicle charging ports 33 arranged on both sides of the service vehicle 5 . When the power of the energy storage battery 18 itself is insufficient, it can also be charged through the service car charging port 32 arranged at the back of the compartment.

A plurality of solar power generation panels 2 are arranged on the top of the service vehicle 5, and can use solar energy to charge the energy storage battery 18 during the day, so as to maximize the utilization of solar energy.

The battery pack storage 23 detachably stores a plurality of different types of battery packs. The types of these battery packs are consistent with the types of battery packs used in operating electric vehicles 6 on the market.

The battery replacement robot 26 is used to replace the battery pack of the target electric vehicle with a battery pack of the same type stored in the battery pack storage warehouse 23 .

The service vehicle positioning module 21 is used to obtain the current location of the service vehicle 5 in real time, and send the current location to the service station 3 through the service vehicle communication module 19 .

The service vehicle information notification module 20 is used to notify the driver of the service vehicle 5 of information such as service routes. When the service car communication module 19 received the service route from the service station 3, the service car information notifying module 20 informed the driver of the service car 5 about the service route, and the driver of the service car 5 followed the service route after seeing the service route. The route travels towards the charging point. At the charging point, select the appropriate charging interface for the target electric vehicle or replace the corresponding battery pack according to the received battery pack model.

As shown in Figure 10, the process of using the above-mentioned electric vehicle power replenishment service system 1 to replenish power for a certain electric vehicle 6 in operation is as follows:

Step 1-1:

During the operation of the electric vehicle 6, the electric vehicle control module 11 controls the battery pack power monitoring module 8 to monitor the remaining power of the battery pack 7, and sends the monitoring result (that is, the value of the remaining power) through the electric vehicle communication module 10 to Judgment module 13, and then enter step 1-2.

Step 1-2:

The judging module 13 judges whether the remaining power counted in a period of time is below the warning power level. When it is below the warning power level, it indicates that the remaining power capacity of the electric vehicle 6 is indeed insufficient, and it needs to be charged or the battery pack needs to be replaced. Go to step 1-3; otherwise, return to step 1-1.

Steps 1-3:

The judging module 13 obtains the power shortage judgment result, and sends the power shortage judgment result to the electric vehicle control module 11 through the electric vehicle communication module 10, and then enters steps 1-4.

Steps 1-4:

After receiving the power shortage judgment result, the electric vehicle control module 11 controls the electric vehicle positioning module 9 to obtain the current position of the electric vehicle 6, and sends the current position, the remaining power of the battery pack and the model number of the battery pack through the electric vehicle communication module 10. Send it to the service subsystem 2, and at the same time control the electric vehicle information notification module 15 to inform the driver of the electric vehicle 6 that the remaining power of the current battery pack 7 is insufficient, so that he can understand the power usage of the battery pack 7, and then enter step 1 -5.

Steps 1-5:

The service station communication module 12 receives the current location, remaining power and battery pack model sent by a certain electric vehicle 6 and sends the above information to the route planning module 14, and then enters steps 1-6.

Steps 1-6:

In fact, the electric vehicle power supply service system can also set up power supply stations in areas with high frequency of use of electric vehicles. Let the electric vehicles to be charged enter the station to enjoy the power supply service, thus combining the fixed power supply method and the mobile power supply method. For the same functional modules in the third embodiment as in the second embodiment, the same names are given and the same descriptions are omitted.

As shown in FIG. 11 , the electric vehicle power supply service system 39 in this embodiment includes a plurality of power supply stations 4 in addition to the structure in the second embodiment.

The supplementary power station 4 is generally set up at scenic spots or traffic hubs where traffic is denser. As shown in FIG. 12 and FIG. 13 , the charging station 4 includes a charging room 35 , a power exchange room 36 , power supply equipment 38 , a communication module 37 of the charging station and a control module 24 of the charging station.

A plurality of charging piles 27 are arranged in the charging room 35 . Each charging pile 27 is provided with different types of charging interfaces. Through these charging interfaces, the charging pile 27 can charge the energy storage battery used by the service vehicle 5 and the battery pack 7 used by the electric vehicle.

A plurality of battery racks 25 are arranged in the battery exchange room 36 . Various types of battery packs 7 are placed on the battery rack 25 . Different types of charging interfaces are also provided on the battery rack 25 . These charging interfaces can charge the battery pack 7 or the energy storage battery 18 through slow charging. The service vehicle 5 returns to the charging station 4 in the evening (21:00-6:00), and fully charges the battery pack and the energy storage battery 18 carried by the slow charging method.

The battery replacement robot 26 is used to replace the full battery pack on the battery rack 25 with the battery pack storage warehouse 23 of the service car 5 or the battery pack that is not full of power in the target electric vehicle.

The power supply equipment 38 is used to provide electric power for the charging pile 27 and the battery rack 25 , including the wind power generating set 28 , the solar generating set 29 and the grid interface 30 . The wind power generating set 28 , the solar generating set 29 and the grid interface 30 are connected to the charging pile 27 and the battery rack 25 through power lines. In this way, the power supply equipment 38 can use wind energy, solar energy and urban power grid for hybrid power supply, effectively ensuring the sufficient power supply of the substation. Wind energy and solar energy are used to supplement power, and when renewable energy is insufficient, the power grid is used to supplement power.

The power substation communication module 37 is used to be responsible for the information exchange between various functional modules and the external information exchange under the control of the power substation control module 24 .

As shown in FIG. 12 , compared with the second embodiment, the storage module 31 of the service station 3 in the third embodiment also stores the locations of all substations.

Compared with the second embodiment, the route planning module 14 can also plan an alternative supplementary circuit for the target electric vehicle, so that the target electric vehicle can find the corresponding supplementary power station according to the alternative supplementary circuit. Specifically, in this embodiment, after the route planning module 14 completes the supplementary circuit and service route planning, it then reads the locations of all supplementary stations and the map of the city where the target electric vehicle is located from the storage module 31. Estimate the driving range supported by its remaining power, and then compare the driving range with the positions of all charging stations, get different comparison results, and determine the target charging station based on these comparison results.
