Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is an application environment diagram of a mobile charging method for an electric vehicle according to the present invention. As shown in fig. 1, the electric vehicle transportation system 10 includes at least one vehicle to be charged 11, a central control system 12, and a mobile charging device 13. The number of vehicles 11 to be charged in fig. 1 may be 1, 2, or more. The vehicle 11 to be charged and the mobile charging device 13 are both in communication with the central control system 12, and when the mobile charging device 13 moves to the vicinity of the vehicle 11 to be charged, for example, the distance from the vehicle 11 to be charged is less than or equal to a preset distance threshold, the mobile charging device 13 can communicate with the vehicle 11 to be charged.
In this implementation scenario, the vehicle 11 to be charged is an electric tractor or a transportation trailer, and travels according to a predetermined transportation track during transportation, in order to improve charging efficiency, an area to be transported, such as a port or a factory area, may be divided into a plurality of districts according to requirements, each district is provided with one mobile charging device 13, and the mobile charging device 13 is configured to charge each vehicle 11 to be charged in the allocated district. The vehicle 11 to be charged monitors the remaining capacity of the vehicle at any time, and when the current remaining capacity is lower than the preset threshold, the vehicle 11 to be charged sends a charging request to the central control system 12, and the central control system 12 reads the charging request and sends the charging request to the mobile charging device 13, so that the mobile charging device 13 can charge the vehicle 11 to be charged according to the charging request.
Since the plurality of vehicles 11 to be charged share one mobile charging device 13, the vehicles 11 to be charged need to estimate the preset threshold according to their own power consumption requirements, such as the weight of the carried goods, the traveling speed, the path condition, and the like, so as to avoid the situation that the plurality of vehicles 11 to be charged need to be charged at the same time and the power is exhausted while waiting for the mobile charging device 13.
Further, when the vehicle 11 to be charged sends the charging request to the central control system 12, the charging request also includes its own condition, such as whether there is a transportation task, remaining capacity, etc., so that when the central control system 12 receives the charging requests of a plurality of vehicles 11 to be charged at the same time, the charging requests can be sorted according to the own condition of the vehicles 11 to be charged, for example, the charging request of the vehicle 11 to be charged having the transportation task is sent to the mobile charging device first. In another implementation scenario, the central control system 12 may send both the charging request and the self condition to the mobile charging device 13, and the mobile charging device 13 sorts the charging requests of the vehicles 11 to be charged, for example, first charges the vehicles 11 to be charged with a transportation task in response to the charging requests.
The mobile charging device 13 may be formed by assembling a large-capacity battery system on a mobile device, a generator set on a mobile device, or a generator set and a battery pack on a mobile device.
Further, the mobile charging device 13 may also monitor the remaining power of itself in real time, and when the current remaining power is lower than the preset threshold, send a charging notification to the central control system 12, and the central control system 12 dispatches or goes to a charging place by itself to charge. At this time, the central control system 12 schedules another mobile charging device 13 to replace the charging operation of the mobile charging device 13 being charged.
In another implementation scenario, the mobile charging facility 13 and the vehicle 11 to be charged may directly communicate without providing the central control system 12.
Referring to fig. 2, fig. 2 is a schematic flow chart of a mobile charging method for an electric vehicle according to a first embodiment of the present invention. The invention provides a mobile charging method of an electric vehicle, which comprises the following steps:
s101: and acquiring a charging request of the vehicle to be charged, and moving to a preset charging position according to the charging request.
In a specific implementation scenario, a vehicle to be charged sends a charging request to a central control system, the charging request includes a current position of the vehicle to be charged, the central control system forwards the charging request to a mobile charging device, and the mobile charging device moves to a preset charging position according to the charging request. In this implementation scenario, the preset charging position is a position range, that is, the position where the charging operation of the vehicle to be charged can be performed can be both used as the preset charging position. In other implementation scenarios, the preset charging position may also be a specific position, such as specific coordinates. In other implementation scenarios, the vehicle to be charged may directly send the charging request to the mobile charging device.
In the implementation scenario, the preset charging position is obtained by the mobile charging device according to the current position of the vehicle to be charged, and in other implementation scenarios, the preset charging position can also be obtained by the central control system according to the current position of the vehicle to be charged and sent to the mobile charging device.
When the vehicle to be charged is in a static state, the mobile charging equipment moves to a preset charging position corresponding to the current position, and then the vehicle to be charged can be charged. When the vehicle to be charged is in a motion state, the mobile charging device can estimate the predicted running position of the vehicle to be charged according to the motion track of the vehicle to be charged, and obtain a preset charging position corresponding to the predicted running position, so that the vehicle to be charged is charged.
S102: and acquiring the charging requirement of the vehicle to be charged, and selecting a charging mode matched with the charging requirement.
In the implementation scenario, after the mobile charging device moves to the preset charging position, the mobile charging device communicates with the vehicle to be charged, the charging requirement of the vehicle to be charged is acquired, and the charging mode matched with the charging requirement is selected. For example, the charging requirements include a current limit, a voltage limit, a power limit, etc. that the battery or battery system of the vehicle to be charged can withstand. And after the charging requirement is acquired, selecting a charging mode in which the current is smaller than the current limit value, the voltage is smaller than the voltage limit value and the power is smaller than the power limit value during charging.
In other implementation scenarios, the mobile charging device communicates with the vehicle to be charged after moving to the communication range of the vehicle to be charged, and selects a charging mode matched with the charging requirement before the mobile charging device reaches the preset charging position, so that the working efficiency can be further improved.
S103: and sensing the charging position of the charging interface of the vehicle to be charged, and connecting the charging interface according to the charging position.
In the implementation scene, the charging connector of the mobile charging equipment is provided with an induction device matched with a charging interface of the vehicle to be charged, and the induction device can be used for inducing the charging position of the charging interface of the vehicle to be charged. And connecting the charging connector of the mobile charging equipment into the charging interface of the vehicle to be charged according to the sensed position of the charging interface. In other implementation scenarios, an image recognition device may be installed on the mobile charging device, and the image recognition device recognizes the charging interface of the vehicle to be charged.
Further, since the mobile charging device needs to charge a plurality of vehicles to be charged, and the plurality of vehicles to be charged may have different charging interfaces, the mobile charging device is configured with a plurality of charging connectors to match with the different charging interfaces. In the implementation scene, the interface type of the vehicle to be charged is identified while the charging position of the charging interface of the vehicle to be charged is sensed, and the vehicle to be charged is connected with the charging interface by adopting a charging connector matched with the charging interface.
S104: and charging the vehicle to be charged according to the charging mode.
In this implementation scenario, the vehicle to be charged is charged according to the charging method selected in step S102. In the charging process, whether the current charging is finished or not is judged by the vehicle to be charged, and the judgment result is sent to the mobile charging equipment and/or the central control system, or whether the current charging is finished or not is judged by the mobile charging equipment.
The mobile charging equipment is communicated with the central control system in the charging process and receives various messages sent by the central control system, such as charging requests of other vehicles to be charged sent by the central control system. After the current charging operation is completed, in response to the charging request of other vehicles to be charged, steps S101-S104 are repeatedly executed to charge the other vehicles to be charged.
According to the above description, in this embodiment, the mobile charging device moves to the preset charging position according to the charging request of the vehicle to be charged, and the matched charging mode is selected according to the charging requirement of the vehicle to be charged, so that the field area required for charging can be effectively reduced, the cruising mileage of the vehicle to be charged is prolonged, the completion of the transportation task of the vehicle to be charged is not influenced, the working efficiency is improved, and the charging cost is reduced.
Referring to fig. 3, fig. 3 is a schematic flow chart of a mobile charging method for an electric vehicle according to a second embodiment of the present invention. The invention provides a mobile charging method of an electric vehicle, which comprises the following steps:
s201: and acquiring a charging request of the vehicle to be charged, and moving to a preset charging position according to the charging request.
In a specific implementation scenario, step S201 is substantially the same as step S101 in the first embodiment of the method for charging an electric vehicle in a mobile manner provided by the present invention, and details thereof are not repeated herein.
S202: and judging whether the spacing distance between the current position of the mobile charging equipment and the vehicle to be charged is smaller than or equal to a preset distance threshold value. If not, step S203 is executed, and if yes, step S204 is executed.
In this implementation scenario, the vehicle to be charged is in a moving state, and the preset charging position is obtained according to the position of the vehicle to be charged when sending the charging request, which may cause the current position of the vehicle to be charged to be mismatched with the preset charging position due to the time delay of message transmission and the time required for the mobile charging device to move to the preset charging position. Therefore, after the vehicle moves to the preset charging position, whether the spacing distance between the current position of the mobile charging device and the vehicle to be charged is smaller than or equal to the preset distance threshold needs to be judged, and if the spacing distance is larger than the preset distance threshold, the charging operation of the vehicle to be charged cannot be realized.
In this implementation scenario, the separation distance may be measured by infrared ranging, ultrasonic ranging, or the like. In other implementation scenarios, whether a reply message of the vehicle to be charged is received or not can be determined by sending a communication message to the vehicle to be charged, if the reply message is received, the spacing distance is smaller than or equal to a preset distance threshold, and if the reply message is not received, the spacing distance is larger than the preset distance threshold.
S203: the method comprises the steps of obtaining a running track of a vehicle to be charged, predicting a predicted running position of the vehicle to be charged on the running track, and moving to the predicted running position.
In this implementation scenario, the separation distance is greater than the preset distance threshold, and the mobile charging device cannot realize the charging operation of the vehicle to be charged. The vehicle to be charged has a fixed running track in the transportation of a port, a factory and other areas, so that the running track of the vehicle to be charged can be obtained, the predicted running position of the vehicle to be charged on the running track can be predicted, and the vehicle to be charged moves to the predicted charging position corresponding to the predicted running position.
The mobile charging equipment can request the central control system to acquire the running track of the vehicle to be charged, or acquire the running track of the vehicle to be charged through related information in the charging request of the vehicle to be charged. After the running track of the vehicle to be charged is obtained, the predicted running position to which the vehicle to be charged moves after a preset time length is predicted, and the mobile charging equipment moves to the predicted charging position corresponding to the predicted running position within the preset time length. Similar to the preset charging position, the predicted charging position is also a position range within which the vehicle to be charged can be charged when the mobile charging device is located. The predicted charging position can be obtained by the mobile charging device according to the predicted running position, and can also be obtained by the central control platform according to the predicted running position.
S204: and acquiring the current speed of the vehicle to be charged, and moving according to the current speed to keep the vehicle to be charged relatively still.
In this implementation scenario, the mobile charging device may move to the predicted charging position, or the mobile charging device moves to the preset charging position, and the distance between the mobile charging device and the vehicle to be charged is less than or equal to the preset distance threshold, the mobile charging device communicates with the vehicle to be charged, obtains the current speed of the vehicle to be charged in real time, and moves according to the current speed of the vehicle to be charged to keep the vehicle to be charged relatively stationary, so that the vehicle to be charged can be charged when the vehicle to be charged is in a moving state.
S205: the charging requirement of the vehicle to be charged is obtained.
In this implementation scenario, step S205 is substantially the same as the portion of acquiring the charging requirement of the vehicle to be charged in step S102 in the first embodiment of the electric vehicle mobile charging method provided by the present invention, and details thereof are not repeated here.
S206: and judging whether the residual electric quantity is higher than a preset high threshold value and/or lower than a preset low threshold value. If the remaining power is lower than the preset low threshold, step S207 is executed, and if the remaining power is higher than the preset high threshold, step S208 is executed.
In this implementation scenario, the charging requirement includes a remaining charge. Different residual capacities correspond to different charging powers.
