Since this power supply control is performed over a wide area for each electric vehicle running along the power supply line, the communication at this time is not Wi-Fi, but mobile communication such as 5G / DSRC wireless communication as an example. It is done based on the system.

As shown in FIG. 1, the wireless charging mobility manager 100 determines the movement of the vehicle while driving and causes the wireless charging power supply equipment communication controller 200 to detect the movement of the vehicle while driving on a segment of the corresponding feed line 400. Manage ON/OFF switching in real time. In Figure 1, each segment is a section controlled by the wireless charging power supply equipment communication controller 200 during each drive to perform power supply, and is a feed line section connected to the wireless charging power supply equipment communication controller 200 during each drive. means. In addition, while driving, the wireless charging power supply equipment communication controller 200 performs the role of turning on/off the inverter 300 of the corresponding segment in real time in the charging infrastructure. The wireless charging power supply equipment communication controller 200 while driving is provided with a power allocator that determines the charging power of the vehicle being charged. The electric vehicle is equipped with a wireless charging electric vehicle communication controller 200, a communication module that supports wireless charging while driving.

The wireless charging mobility manager 100 while driving determines the movement of the vehicle in real time and guides the wireless charging power supply equipment communication controller 200 while driving to turn on/off the segment of the corresponding feed line, and supplies wireless charging power while driving. As an example, the equipment communication controller 200 switches ON/OFF the corresponding inverter 300 of the feed line 400 in real time based on 5G/DSRC communication.

- Wireless charging mobility manager while driving (100): DWNM (Dynamic WPT Mobility Manager)

- Wireless charging power supply equipment communication controller (200) while driving: D-SECC (D-WPT Supply Equipment Communication Controller)

- Wireless charging electric vehicle communication controller while driving (500): D-EVCC (D-WPT Electric Vehicle Communication Controller)

In the following description of the invention, for each component, Korean abbreviations such as mobility manager 100, power supply equipment communication controller 200, electric vehicle communication controller 500, etc. are used, or the English abbreviations above are used interchangeably. Decide to use it.

Figure 2 is a diagram showing a client-server model in the power supply equipment communication controller 200 in the process of providing wireless charging for an electric vehicle while driving, and Figure 3 is a diagram showing the power supply device in the process of providing wireless charging for an electric vehicle while driving. This is a diagram showing a state transition diagram according to the control performance of the supply equipment communication controller 200.

Each power supply equipment communication controller 200 is in a 'standby' state (S100) when an electric vehicle does not enter the feed line section, that is, a segment, that it controls. The electric vehicle communication controller 500 of the moving electric vehicle periodically notifies the current vehicle location to the adjacent power supply equipment communication controller 200, whereby the moving vehicle is connected to the charging area of the adjacent power supply equipment communication controller 200. When entering, the corresponding power supply equipment communication controller 200 creates a D-WPT session (wireless charging session) by the client-server model (S200).

In the wireless charging session 200, power allocation is performed to the vehicle (S201). In other words, a message is sent to the electric vehicle communication controller 500 mounted on the vehicle in question to set the collected power to a certain level. If there are multiple vehicles entering the segment, the power to be allocated to each vehicle is identified and a message is sent to the electric vehicle communication controller 500 of each vehicle to adjust the collected power to the appropriate level. The power supply equipment communication controller 200 turns on the inverter 300 belonging to the corresponding segment to switch to the power supply state, and each electric vehicle communication controller (S201) receives the power allocation message as described above (S201). 500) adjusts the power of the current collector mounted on the vehicle accordingly, and receives power wirelessly transferred from the feed line 400 while passing through the feed line (S202).

When the electric vehicle communication controller 500 of the vehicle determines that it has entered a charging segment, it periodically transmits its location information wirelessly, and the power supply equipment communication controller 200 that has entered the segment is located at this location. By continuously checking information (S203), it is determined whether the vehicle is at a point where it leaves its segment and moves to another segment, that is, whether it has reached the power handover stage (S204). If power handover is not yet at the point where power handover will occur, the power supply equipment communication controller 200 continues to determine the status of the vehicles entering it and updates the power allocation (S205) so that each electric vehicle communication controller 500 ) to adjust the collecting power (S202). If it is a point where handover will occur, power handover is performed (S206) so that the vehicle receives power from the power supply equipment communication controller 200 of the next segment into which the driving vehicle will enter, and then power is supplied to its own segment. Stop to release power handover (S207). Below, with reference to FIG. 4, the above-described power handover sequence will be described in more detail.

Figure 4 is a diagram showing a sequence in which power handover is performed in the process of providing wireless charging for an electric vehicle while driving.

The electric vehicle communication controller (D-SECC 1) 500 in a moving vehicle periodically reports the current vehicle location to the power supply equipment communication controller (D-SECC 2) 200.1 closest to the vehicle's direction of travel. In other words, the power supply equipment communication controller (D-SECC 1) (200.1), based on its own location information provided periodically (S701) by the moving vehicle, determines whether the vehicle is connected to the next power supply equipment communication controller (D-SECC) in the vehicle's direction of travel. 2) When it is determined that the charging location has been reached (200.2), a power handover request is sent to the mobility manager 100 (S702), and the mobility manager 100 sends a power handover instruction message in response (S702). S703).

Thereafter, the mobility manager 100 sends an instruction message to register the electric vehicle communication controller 500 of the vehicle to the next power supply equipment communication controller (D-SECC 2) (200.2) (S704), and the power supply equipment The communication controller (D-SECC 1) (200.1) sends the next power supply equipment communication controller (D-SECC 2) (200.2) information to the vehicle's electric vehicle communication controller (500) (S705, S706). In addition, the power supply equipment communication controller (D-SECC 1) (200.1) transmits a response message to the power handover instruction message (S703) received from the mobility manager 100 back to the mobility manager 100 (S707).

The electric vehicle communication controller 500, which has received (S705) the information of the next power supply equipment communication controller (D-SECC 2) (200.2) from the power supply equipment communication controller (D-SECC 1) (200.1), supplies the power. A registration request message is sent to the equipment communication controller (D-SECC 2) (200.2) (S708). The power supply equipment communication controller (D-SECC 2) (200.2) turns on the inverter and starts transmitting power to the vehicle (S709), and transmits a response message to the registration request to the electric vehicle communication controller 500 ( S710).

In addition, the power supply equipment communication controller (D-SECC 2) (200.2) transmits a response message to the registration request to the mobility manager 100 (S711), and the mobility manager 100 transmits a response message to the power supply equipment communication controller (D-SECC 1). ) (200.1) is notified that the power supply equipment communication controller has been changed (S712). Accordingly, the power supply equipment communication controller (D-SECC 1) (200.1) changes the power supply equipment communication controller to the electric vehicle communication controller (500). A notification is sent (S713), and the inverter is turned off to end power transfer for the segment (S714) and cancel the power handover. Of course, if another vehicle is driving in the segment, the inverter is turned on. There will be.

As shown in the above-mentioned process, at the time of power handover, the power supply communication controller (D-SECC 2) (200.2) begins to supply power to the vehicle in question first and then As the power supply of SECC 1) (200.1) is terminated, a section where power supply overlaps between segments occurs for a short period of time. This is to prevent a section in which the power supply to the vehicle is cut off.

Figure 5 is a diagram illustrating a state transition diagram according to the control performance of the wireless charging electric vehicle communication controller 500 mounted on the vehicle in the process of providing wireless charging for the electric vehicle while driving.

In a vehicle that is in operation (S300), the electric vehicle communication controller 500 wirelessly transmits its location information to surrounding areas periodically even when it is not passing through a power supply line (S30). Step S203 of FIG. 3 also periodically provides its own location information, but this is provided to the power supply communication controller 200 for power handover to the next segment while charging continues when entering the segment section of the feed line. As location information, messages are sent at very short intervals (for example, 10ms). This provision of location information is shown in step S40 in FIG. 5.

However, step S30, as described above, provides location information for the purpose of finding a feeding segment while driving in a location other than the feeding segment section, that is, while wireless power is not yet transmitted to the vehicle, and is much longer. A message is sent at intervals and a response scanning signal is waited for from the power supply equipment communication controller 200 (S301). The mobility manager 100, which has received such location information provision (S30), transmits information on the power supply equipment communication controller 200 capable of charging at the location of the vehicle to the electric vehicle communication controller 500 of the vehicle, When receiving this, the electric vehicle communication controller 500 starts a wireless charging session (S400). The subsequent process is a state transition sequence in which wireless charging is performed in a segment section of the specific power supply equipment communication controller 200 and power handover is performed according to the vehicle progress. In FIG. 3, the power supply equipment communication controller 200 The sequence from the perspective of, and FIG. 5 is a process viewed from the perspective of the electric vehicle communication controller 500.

That is, the electric vehicle communication controller 500, which has received power supply equipment communication controller information from the mobility manager 100 (S302, S705 in FIG. 4), checks whether it is on the line of the power supply line (S401). The driver can adjust it, but if the vehicle has an automatic alignment function, it can be controlled to adjust automatically. The power supply equipment communication controller 200 transmits a power allocation message to the vehicle, and the electric vehicle communication controller 500 receives this and adjusts its collected power accordingly (S402), and transmits the collected power wirelessly. It is delivered to (S403). The power allocation message has been described in detail with reference to FIG. 3.

In this case, as described above, the own location information is provided at much shorter intervals (for example, 10 ms) than when providing location information during charging standby operation (S30), and this location information is provided in step S203 of FIG. 3. It means the same thing as provision, and this is to enable power handover to be performed to the power supply equipment communication controller 200 of the next segment depending on the position as the vehicle progresses. In other words, the current power supply equipment communication controller 200 continuously determines whether the vehicle is in a power handover position (S404), and if not yet, continuously sends a power allocation adjustment message to the electric vehicle communication according to the updated number of vehicles in the current segment. It is transmitted to the controller 500, and the electric vehicle communication controller 500 receives it, adjusts its own collected power (S405), and receives the collected power (S403). In addition, the electric vehicle communication controller 500 continuously checks whether the vehicle on which it is mounted is on the power supply line (S406) and, if it has an alignment function, aligns and adjusts the vehicle to fit the power supply line.

If the current power supply equipment communication controller 200 determines that the vehicle is in the power handover position (S404), power handover processing (S500) begins. That is, this power handover processing has been described in detail with reference to FIG. 4. Accordingly, when the electric vehicle communication controller 500 is registered as a new target power supply equipment communication controller 200, wireless power transfer to the vehicle begins by the target power supply equipment communication controller 200 (S501, S709, see FIG. 4), the existing power supply equipment communication controller 200, which has received a change notification of the power supply equipment communication controller from the mobility manager 100, terminates power transfer (S714, see FIG. 4), and the existing power supply equipment Reception of collected power from the communication controller 200 ends (S502).

As described above with reference to FIG. 4, at the time of power handover, the target power supply equipment communication controller (D-SECC 2) (200.2, see FIG. 4) first starts supplying power to the vehicle in question, and then the existing power supply equipment As the power supply to the communication controller (D-SECC 1) (200.1, see Figure 4) is terminated, a section where power supply overlaps between segments occurs for a short period of time, resulting in a section where the power supply to the vehicle is cut off. This is to prevent it from happening.
