Detailed Description
The core of the application is to provide a dynamic charging system for vehicles on the road surface, a wireless charging transmitting device and a control method thereof, so as to effectively improve the charging efficiency and save the equipment cost.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all 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 application.
Referring to fig. 1 and fig. 2, fig. 1 is a view illustrating an application scenario of a dynamic charging of a road vehicle according to the present application; fig. 2 is a block diagram of a wireless charging transmitting device in a dynamic charging system for a road vehicle provided by the present application.
As shown in fig. 1, the wireless charging transmitter 2 in the dynamic charging system for road vehicles provided by the present application can be respectively installed in a plurality of road sections on the ground, and when a vehicle equipped with a corresponding wireless charging receiver 1 runs in a certain road section, the wireless charging transmitter 2 in the road section can start the wireless charging operation to charge the vehicle-mounted battery of the vehicle.
In the case of dividing the links, those skilled in the art can design the length of each link according to actual conditions such as the terrain, the route angle, and the surrounding obstacles at the time of application. In addition, as shown in fig. 2, the road sections may be discontinuously laid, so as to more flexibly adapt to different landforms. In fact, especially for some buses and other vehicles adopting fixed operation lines, a person skilled in the art can design a certain spacing distance for two adjacent road sections according to the cruising ability of a vehicle-mounted power battery and the like, divide the vehicle operation line into a plurality of discontinuous road sections, and realize the segmented supervision of the whole long-distance operation line.
As shown in fig. 2, the wireless charging transmitter 2 in the dynamic charging system for road vehicles provided by the present application includes a road segment controller 21, a plurality of transmitting coils 22 arranged on the road segment and ground, and a power supply controller 23 thereof;
the position of each transmitting coil 22 is stored in the road segment controller 21 and is connected with each power supply controller 23, the road segment controller 21 is used for obtaining the vehicle position of the vehicle running on the road surface, if the vehicle runs in the range of the road segment where the road segment controller 21 is located, the power supply controller 23 of the transmitting coil 22 located in the coupling range of the receiving coil 13 of the vehicle in the road segment is determined as the power supply controller to be started, and the power supply controller to be started is started so as to charge the vehicle.
Specifically, the road section division is carried out on different areas of the road surface, one wireless charging transmitting device 2 is arranged in each road section, and each wireless charging transmitting device 2 is managed and controlled by one road section controller 21. When the vehicle loaded with the wireless charging receiving device 1 runs to a corresponding road section on the road surface, the wireless charging transmitting device 1 of the road section can transmit energy to the wireless charging receiving device 1 under the control of the road section controller 21 to charge the vehicle.
Each wireless charging and transmitting device 2 provided by the present application is provided with a segment controller 21 and a plurality of transmitting coils 22, and each transmitting coil 22 is provided with a corresponding power supply controller 23 so as to control the input of the transmitting energy of the corresponding transmitting coil 22 under the control of the segment controller 21. One power supply controller 23 may control one or more transmitting coils 22, and different numbers of transmitting coils 22 may be provided for wireless charging and transmitting devices 2 in different road sections.
The power supply controller 23 is a power conversion part for wireless charging and transmitting, and when the power supply controller is started, the power supply controller can invert and output the electric energy input by the power supply to the connected transmitting coil 22 according to the working frequency of the resonant topological frequency control system, and the transmitting coil 22 transmits the energy to the receiving coil 13 on the vehicle in an electromagnetic coupling mode. The power supply can be from a power grid, wind power generation energy storage or photovoltaic power generation energy storage on the side of a road and the like, and the power supply controller 23 can be connected with the power supply by adopting a corresponding power supply input interface.
The start of the power conversion by the power supply controller 23 is specifically controlled by the segment controller 21. As a preferred embodiment, the communication between the segment controller 21 and each power supply controller 23 may specifically adopt a convenient CAN bus communication mode. Of course, those skilled in the art may also use other methods such as RS485, fiber communication, network communication, etc., which are not limited in this application.
The road segment controller 21 is a control core in the whole road segment, and it can acquire the relevant information of the vehicle, i.e., the vehicle position, by performing wireless communication with the controller on the vehicle-mounted side (i.e., the receiving controller 11 in fig. 2), so as to determine the power supply controller to be started according to the vehicle position, thereby starting the power supply controller to be started, and the energy is transmitted by the corresponding transmitting coil 22 to charge the vehicle.
The wireless communication between each segment controller 21 and the receiving controller 11 may specifically be a communication method such as WiFi, RF433, DSRC, or 5G network, and a person skilled in the art may select a communication method with high real-time performance and strong anti-interference capability, which is not limited in this application. Of course, it is easily understood that the length of a single segment may be set according to the effective communication distance of the selected wireless communication mode, and the number of the transmitting coils 22 in the segment may be further determined in combination with the size of the transmitting coil 22.
It is easy to understand that the transmitting coils 22 in the road section are sequentially arranged on the road surface, the road section controller 21 stores the installation positions of the transmitting coils 22 in the road section in advance, so that the installation positions can be compared with the vehicle position to determine the transmitting coils 22 located in the coupling range of the receiving coil 13, and then the power supply controllers 23 corresponding to the transmitting coils 22 are the power supply controllers to be started.
In the present application, in one road segment, the road segment controller 21 controls all the power supply controllers 23 in the whole road segment, so that the receiving controller 11 only needs to perform information interaction with the road segment controller 21, and each power supply controller 23 does not need to be configured with a wireless communication module and does not need to perform information interaction with the receiving controller 11. Therefore, the interactive workload of the receiving controller 11 can be greatly reduced, the configuration requirement of the wireless communication module is effectively reduced, and the equipment cost is reduced.
In summary, the normal operation process of the power supply controller 23 of the wireless charging transmitting device 2 can be divided into three states of standby, starting and charging, and the normal operation process of the receiving coil 13 of the wireless charging receiving device 1 can be divided into two states of charging and non-charging.
While the vehicle is traveling, the reception controller 11 continuously transmits the vehicle position to the segment controller 21 of each segment within the wireless communication range. After detecting that the vehicle is traveling within the current road section, the road section controller 21 of the road section where the vehicle is located further compares the vehicle position with the installation positions of the transmitting coils 22 in the current road section, so as to determine the transmitting coil 22 (which may be referred to as a transmitting coil to be started) located within the coupling range of the receiving coil 13, and the corresponding power supply controller 23 can be determined as the power supply controller to be started. The segment controller 21 sends a start instruction to the power supply controller to be started, so that the power supply controller to be started is switched from the standby state to the start state.
The power supply controller 23 in the standby state does not start power conversion for the power supply source to be connected, and only a basic circuit for communication with the segment controller 21 and the like is operated. After receiving the start instruction, the power supply controller 23 starts the power conversion circuit, the transmitting coil 22 starts to transmit electromagnetic energy, and the power supply controller 23 is in a start state. If the activated transmitting coil 22 is within the coupling range with the receiving coil 13 of the vehicle, the transmitting coil 22 facilitates the receiving coil 13 to generate energy transmission through electromagnetic coupling, and the energy is transmitted to the vehicle side where the receiving coil 13 is located. At this time, the power supply controller 23 and the receiving coil are in a charged state.
Since the vehicle is dynamically running on the road surface, the relative positional relationship of the receiver coil 13 and the transmitter coil 22 changes as the vehicle moves. When the distance between the two coils is not within the coupling range, the transmitting coil 22 cannot induce a current in the receiving coil 13 any more, so that the energy transmitted by the transmitting coil 22 cannot be transferred to the receiving coil 13, the power supply controller changes from the charging state to the starting state, and the receiving coil 13 changes from the charging state to the non-charging state (in the case that no other transmitting coil 22 charges the receiving coil 13).
It will be readily appreciated that, in order to save energy, the segment controller 21 may further turn off the already-activated power supply controller 23 after the receiving coil 13 is not within the coupling range of the transmitting coil. When receiving the shutdown command from the segment controller 21, the power supply controller 23 switches the power conversion circuit off to the standby state.
Therefore, the wireless charging transmitting device in the dynamic road vehicle charging system can be respectively arranged in each road section of the ground, and the power supply controller of the transmitting coil at the corresponding position is started through acquiring the position information of the vehicle in real time, so that the energy transmission work is started to charge the vehicle, the charging without stopping in the driving process is realized, the searching time and the charging waiting time of the charging pile are saved, and the use by a user is greatly facilitated. Meanwhile, the charging control of the branch sections can be adopted, and the transmitting coils in the road section are uniformly managed and controlled in order by each section controller, so that the using quantity of related control equipment and wireless communication equipment in the road section is saved, the equipment cost is reduced, frequent direct communication between each power supply controller and a vehicle side is avoided, and the charging control efficiency is improved.
Referring to fig. 3, fig. 3 is a block diagram of a dynamic charging system for a road vehicle according to the present disclosure. As shown in fig. 3, the dynamic charging system for road vehicles provided by the present application comprises a wireless charging receiving device 1 disposed on the vehicle-mounted side and a plurality of wireless charging transmitting devices 2 disposed on different road and ground sides;
the wireless charging receiving device 1 comprises a receiving controller 11, a vehicle-mounted positioning device 12 connected with the receiving controller, a receiving coil 13 used for being in resonance coupling with a transmitting coil 22 to pick up energy, and a power converter 14 connected with the output end of the receiving coil, wherein the output end of the power converter 14 is connected with a vehicle-mounted power supply battery; the segment controller 21 and the receiving controller 11 each include a wireless communication module so that the receiving controller 11 transmits the vehicle position to the segment controller 21.
As shown in fig. 3, the wireless charging receiving apparatus 1 mounted on the vehicle includes a receiving coil 13, which can pick up energy in the process of electromagnetic coupling with a transmitting coil 22, so that the picked-up energy is stored in the vehicle-mounted power supply battery after being power-converted by the power converter 14, thereby charging the vehicle. The receiving controller 11 in the wireless charging receiving apparatus 1 also has a wireless communication module, is connected to the on-vehicle positioning device 12 by a CAN bus or the like, and is configured to wirelessly communicate with each segment controller 21 and transmit the vehicle position, which is the positioning result of the on-vehicle positioning device 12, to each segment controller 21.
It should be noted that, currently, commercially available vehicles generally provide vehicle-mounted positioning services, that is, a positioning device is already installed in the vehicle, and at this time, the positioning device already configured in the vehicle may be used as the vehicle-mounted positioning device 12 in the present application. The receiving controller 11 may be connected to a vehicle CAN bus in particular in order to enable CAN bus communication with the positioning device. Generally, the connection with a vehicle controller, a battery management system and a vehicle automatic driving system of a vehicle is realized simultaneously through a vehicle CAN bus, so that more vehicle information CAN be further acquired.
The vehicle-mounted positioning device 12 may be a GPS, a compass, or a pulse ranging system, and may be selected and set by a person skilled in the art, which is not limited in the present application. Of course, the higher the positioning accuracy, the more accurate the control effect is. The positioning accuracy can be made much smaller in order of magnitude than the length dimension of the transmitter coil 22 in the direction of travel in order to accurately control the position and number of transmitter coils 22 located within the coupling range of the receiver coil 13.
It can be seen that, in the dynamic charging system for vehicles on road surfaces provided by the application, the wireless charging transmitting devices 2 arranged in the ground range of each road section can interact with the wireless charging receiving devices 1 in the vehicles in real time to acquire the position information of the vehicles, so that the power supply controller 23 of the transmitting coil 22 at the corresponding position is started, the energy transmission work is started to charge the vehicles, the charging without stopping in the driving process is realized, the searching time and the charging waiting time of the charging pile are saved, and great convenience is brought to users. Meanwhile, the charging control of the branch sections is adopted, and the transmitting coils 22 in the road section are uniformly managed and controlled in order by the controller 21 of each road section, so that the using quantity of related control equipment and wireless communication equipment in the road section is saved, the equipment cost is reduced, frequent direct communication between each power supply controller 23 and a vehicle side is avoided, and the charging control efficiency is improved.
The application provides a road vehicle developments charging system, on the basis of above-mentioned embodiment:
referring to fig. 4, fig. 4 is a diagram of another application scenario of dynamic charging of a road vehicle provided in the present application. As shown in fig. 4, as a preferred embodiment, the segment controller 21 of each wireless charging and transmitting device 2 is connected to the monitoring terminal 3 in a networking manner, and is configured to send charging status data to the monitoring terminal 3 and receive a control instruction sent by the monitoring terminal 3.
Specifically, each wireless charging and transmitting device 2 and the monitoring terminal 3 may form a network connection topology through networking technology to perform network communication. Each segment controller 21 may transmit the charge state data to the monitor terminal 3 for viewing by the user.
The charging state data may specifically include information such as vehicle position acquired from the receiving controller 11, ID information of the currently activated transmitting coil 22 or the power supply controller 23, and state information (e.g., real-time power of power supply, charging duration, etc.) acquired from the power supply controller 23; fault information obtained by detecting the health state of the segment controller 21 and each power supply controller 23 can be included so as to give a fault warning; the power consumption information obtained by the electric quantity metering device on the input side of the power supply can be further included; in addition, the dynamic charging system for the road vehicle provided by the application can be further additionally provided with some auxiliary devices on the ground, such as road foreign matter detection devices, living body protection devices and the like, and relevant information is displayed on the monitoring terminal 3.
On the other hand, the user may send a control command, such as a shutdown command, to the road segment controller 21 of a certain road segment through the monitoring terminal 3, so that the staff may perform maintenance work, such as maintenance and repair, on the wireless charging and transmitting device 2 in the road segment. Due to the adoption of the segmented control, the maintenance of a certain road section does not influence the charging operation of the wireless charging transmitting device of other road sections on the vehicle.
Of course, it is easy to understand that the monitoring terminal 3 and each segment controller 21 need to perform a handshake operation and a heartbeat check operation in networking communication before performing data information interaction.
As a preferred embodiment, the segment controller 21 further includes a positioning module, configured to obtain an installation position of the segment controller 21, so that the segment controller 21 generates a position of each transmitting coil 22 according to the installation position and a preset relative position of each transmitting coil 22 in the road segment.
Specifically, as mentioned above, each segment controller 21 stores the position of each transmitting coil 22 in the segment, and preferably, the position of each transmitting coil 22 can be generated by the positioning module of the segment controller 21. Specifically, after the segment controller 21 is installed, the installation position of the segment controller 21 can be located by using the locating module, and then the specific position of each transmitting coil 22 is determined according to the number of the transmitting coils 22 in the current segment and the installation interval (i.e. the relative position in the segment).
As a preferred embodiment, the segment controller 21 is further configured to:
the installation positions of the other segment controllers 21 are acquired, and the adjacent segment controllers are confirmed, so that when the vehicle runs off the section where the segment controller 21 is located, prompt information is sent to the adjacent segment controllers in the driving direction.
Specifically, each segment controller 21 may further perform information interaction with an adjacent segment controller in the driving direction, and the adjacent segment controller may enable the wireless communication module to perform wireless communication with the receiving controller 11 on the vehicle after receiving the prompt information, and turn off the wireless communication module at other times, so as to further reduce power consumption.
As a preferred embodiment, the segment controller 21 is specifically configured to:
according to pr＝pc+dcrCalculating the position of the receiving coil 13 of the vehicle, the condition d will be satisfiedtr＝|pt-prThe power supply controller 23 of the transmitting coil 22 with | < δ is determined as the power supply controller to be started;
wherein p isrFor receiving the position of the coil 13, pcAs the position of the vehicle, dcrFor a predetermined relative distance, p, of the on-board positioning device 12 from the receiving coil 13tTo transmit the position of the coil 22, dtrδ is the relative distance of the receiver coil 13 and the transmitter coil 22, and is a preset distance threshold.
In particular, the amount of the solvent to be used,obtaining the vehicle position p at the segment controller 21cIn this case, the distance d may be further determined according to the preset relative distance between the on-board positioning device 12 and the receiving coil 13crThe position p of the receiving coil 13 (more precisely, the position which may be the center of the coil) is foundrAnd further determining the transmitting coil 22 with the relative distance from the receiving coil 13 smaller than the preset distance threshold value delta as a transmitting coil to be started, and determining the corresponding power supply controller as a power supply controller to be started.
It should be noted that, in theory, the preset distance threshold δ may be the maximum relative distance d between the receiving coil 13 and the transmitting coil 22 when coupling can be generated. In practice, however, it is easy to understand that, due to the problem of communication delays, when the segment controller 21 activates the power supply controller to be activated, the vehicle has actually deviated from the vehicle position received by the segment controller 21, and therefore, the preset distance threshold δ may be taken to a certain preset value greater than the maximum relative distance d, in order to guarantee, to the maximum extent, that there are (even a sufficient number of) transmitting coils 22 to charge the receiving coils 13.
As a preferred embodiment, the segment controller 21 is further configured to:
before the power supply controller to be started is started so as to charge the vehicle, wireless communication is carried out with the receiving controller 11, the charging requirement information of the vehicle where the receiving controller 11 is located is obtained, and the charging requirement information is sent to the power supply controller to be started, so that the power supply controller to be started configures charging output power according to the charging requirement information.
As described above, in the dynamic charging system for road vehicles provided by the present application, the receiving controller 11 may be connected to a vehicle CAN bus, obtain charging requirement information (for example, required voltage, required current, required power, etc.) of the vehicle, and send the charging requirement information to the segment controller 21, so that the segment controller 21 sends the charging requirement information to the power supply controller to be started, and the power supply controller to be started outputs corresponding charging power according to the charging requirement information after being started.
Therefore, the one-time complete working process of the segment controller 21 can be divided into several stages of wireless communication interaction, charging decision, charging parameter configuration, charging start control, charging data interaction and charging shutdown control. The road segment controller 21 obtains the charging demand information and the vehicle position in the wireless communication interaction stage with the receiving controller 11, determines the power supply controller to be started in the charging decision stage, sends the charging demand information to the power supply controller to be started in the charging parameter configuration stage, starts the determined power supply controller to be started in the charging start control stage, obtains the charging state data of the transmitting coil 22 when the vehicle is charged in the charging data interaction stage, and uploads the charging state data to the monitoring terminal 3 until the started power supply controller 23 is closed in the charging shutdown control stage.
As a preferred embodiment, the segment controller 21 is further configured to:
before the charging demand information of the vehicle in which the receiving controller 11 is located is acquired, the vehicle parameter information of the vehicle is acquired, whether the vehicle is an authorized vehicle or not is judged, if yes, wireless communication with the receiving controller 11 is continued, and if not, wireless communication with the receiving controller 11 is stopped.
Specifically, after establishing wireless communication with the vehicle, the road segment controller 21 may first perform charging authorization identification on the vehicle, identify whether the vehicle is equipped with the corresponding wireless charging receiving device 1, and if so, the vehicle with the charging authorization may continue to perform wireless communication so as to complete wireless charging; if not, the wireless communication needs to be stopped for the vehicle without charging authorization.
The vehicle parameter information may specifically include any one or any combination of the following: wireless communication protocol version, power supply power class, receive coil type, resonant topology type, receive coil mechanical air gap, and the like.
As a preferred embodiment, the segment controller 21 is further configured to:
and performing wireless communication with the receiving controller 11 to acquire the speed of the vehicle where the receiving controller 11 is located, so as to adjust the preset distance threshold value delta according to the speed and the communication delay time of the road vehicle dynamic charging system.
Specifically, in consideration of the communication delay problem in practical application as described above, the receiving controller 11 in the present application may specifically send the vehicle speed to the segment controller 21 when performing information interaction with the segment controller 21, so that the segment controller 21 may adjust the preset distance threshold δ in real time by combining the vehicle speed and the communication delay time to ensure that the number of activated transmitting coils 22 is kept reasonable, and reactive power loss and energy radiation are reduced as much as possible. It will be readily appreciated that the greater the vehicle speed, the greater the preset distance threshold δ, and the more transmitting coils 22 that are activated; the smaller the vehicle speed, the smaller the preset distance threshold δ, and the less the transmitter coil 22 is activated.
As a preferred embodiment, the wireless communication module of the segment controller 21 is a multi-channel wireless communication module;
the segment controller 21 is also configured to:
after the vehicle has traveled away from the link where the link controller 21 is located, the wireless communication channel allocated for the reception controller 11 is cancelled.
Specifically, since many vehicles are generally traveling on the road surface, it is necessary to realize simultaneous communication between the segment controller 21 and the plurality of reception controllers 11 by using multichannel wireless communication. Meanwhile, when the vehicle leaves the road segment where the certain road segment controller 21 is located, the road segment controller 21 immediately releases resources so as to repeatedly use the wireless communication channel to continue communication with the vehicle receiving controller 11 of the next road segment to be driven.
The following describes a method for controlling dynamic charging of a road vehicle provided by the present application.
