The control unit 14 of the charge communication control device 1 receives the information related to the vehicle speed at the CAN communication unit 13, and determines whether the vehicle C travels at a low speed or stops (step S11). For example, if the speed is less than 10 km / h, it is determined that the speed is low. If it is determined that the vehicle C is traveling at a high speed (step S11: NO), the control unit 14 ends the process. When it is determined that the vehicle C is traveling at a low speed or is stopped (step S11: YES), the control unit 14 controls the inlet of the vehicle C based on the detection result output from the connection detection unit 15 It is determined whether it is connected to 7 (step S12). If it is determined that the charging gun is connected (step S12: YES), the control unit 14 causes the PLC communication unit 12 to start PLC communication with the second charging device 4 (step S13).

  The charge ECU 2 transmits / receives information relating to charge control to / from the second charge device 4 by the charge communication control device 1, and controls charge by the power transmitted from the second charge device 4 through the charge cable 41 (step S14). Next, the charge ECU 2 monitors the state of the battery 5 and determines whether the battery 5 is fully charged (step S15). If it is determined that the battery 5 is not fully charged (step S15: NO), the charge ECU 2 returns the process to step S14 and continues charge control. If it is determined that the battery 5 is fully charged (step S15: YES), the charge ECU 2 stops charging by the second charging device 4 (step S16), and the process ends.

  If it is determined that there is no access point of the first charging device 3 (step S17: NO), the control unit 14 ends the process. If it is determined that there is an access point of the first charging device 3 (step S17: YES), the control unit 14 causes the wireless communication unit 11 to start wireless communication with the first charging device 3 (step S18) . Next, the control unit 14 determines whether or not the charging gun is connected (step S19). When it is determined that the charging gun is not connected (step S19: NO), the charging ECU 2 transmits / receives information related to charging control to / from the first charging device 3, and contactless transmission is performed from the first charging device 3 Non-contact charging is performed using the stored power (step S20). Next, the charge ECU 2 monitors the state of the battery 5 and determines whether the battery 5 is fully charged (step S21).

If it is determined that the battery 5 is in a fully charged state (step S21: YES), the charge ECU 2 stops noncontact charging by the first charging device 3 (step S22), and ends the process.

  When it is determined in step S19 that the charging gun is connected (step S19: YES), the control unit 14 transmits a signal to stop the noncontact charging to the charging ECU 2 to stop the noncontact charging (step S23). Then, the control unit 14 suspends the wireless communication by the wireless communication unit 11 (step S24), and starts the communication by the PLC communication unit 12 (step S25). Next, the control unit 14 establishes communication with the second charging device 4 and determines whether charging by the second charging device 4 is possible (step S26). Specifically, charging ECU 2 determines whether or not charging by second charging device 4 is possible, and transmits the determination result to charging communication control device 1. The charge communication control device 1 refers to the determination result of the charge ECU 2 and determines whether charging by the second charging device 4 is possible.

  When it is determined that charging by the second charging device 4 is not possible (step S26: NO), the control unit 14 resumes wireless communication by the wireless communication unit 11 (step S30), and returns the process to step S20. 1. The noncontact charging by the charging device 3 is resumed.

  When it is determined that charging by the second charging device 4 is possible (step S26: YES), the control unit 14 disconnects wireless communication by the wireless communication unit 11 (step S27). Next, the charging of the battery 5 by the second charging device 4 is controlled in the same processing procedure as in steps S14 to S16 (steps S28 to S30), and the process ends.

  According to the charge communication control device 1 and the charge communication control method according to the first embodiment, when communication with the first charging device 3 and the second charging device 4 is possible, the second charging device 4 having high charging efficiency is selected.

The wireless communication with the first charging device 3 is disconnected, and the communication with the second charging device 4 is shifted to wired communication. If communication with the second charging device 4 is not established or charging by the second charging device 4 is not possible, wireless communication with the first charging device 3 is resumed. Therefore, when the second charging device 4 can not charge, it is possible to avoid useless communication processing such as disconnection and reconnection of wireless communication.

  In the first embodiment, although the second charging device 4 for supplying direct current is described, the second charging device 4 may be configured to supply an alternating current to the vehicle C to charge the battery 5.

If it is determined that the vehicle C is traveling at high speed (step S51: NO), the control unit 14 ends the process. When it is determined that the vehicle C is traveling at a low speed or is stopped (step S51: YES), the control unit 14 searches for an access point and determines whether there is an access point of the first charging device 3 or not. (Step S52). If it is determined that there is an access point of the first charging device 3 (step S52: YES), the control unit 14 causes the wireless communication unit 11 to start wireless communication with the first charging device 3 (step S53) . Next, the control unit 14 determines whether or not the charging gun is connected (step S54). When it is determined that the charging gun is connected (step S54: YES), the control unit 14 searches for an access point and determines whether there is an access point of the second charging device 204 (step S55). When it is determined that there is an access point of the second charging device 204 (step S55: YES), the control unit 14 executes processing of step S60 and later, which is described later, that is, processing related to charging by the second charging device 204. When it is determined that there is no access point of the second charging device 204 (step S55: NO) or when it is determined that the charging gun is not connected (step S54: NO), the charging ECU 2 and the first charging device 3 The information related to charge control is transmitted and received between them, and non-contact charge by the electric power non-contact transmitted from the first charging device 3 is controlled (step S56). Next, the charge ECU 2 monitors the state of the battery 5 and determines whether the battery 5 is fully charged (step S57). When it is determined that the battery 5 is not fully charged (step S57: NO), the charge ECU 2 returns the process to step S54 and continues charge control. If it is determined that the battery 5 is fully charged (step S57: YES), the charge ECU 2 stops noncontact charging by the first charging device 3 (step S58), and ends the process.

  When it is determined in step S52 that there is no access point of the first charging device 3 (step S52: NO), the control unit 14 determines whether there is an access point of the second charging device 204 (step S59). If it is determined that there is no access point of the second charging device 204 (step S59: NO), the control unit 14 ends the process. When it is determined that there is an access point of the second charging device 204 (step S59: YES), the control unit 14 causes the wireless communication unit 11 to start wireless communication with the second charging device 204 (step S60). . Then, it is determined whether or not the charging gun is connected (step S61). If it is determined that the charging gun is not connected (step S61: NO), the control unit 14 ends the process. If it is determined that the charging gun is connected (step S61: YES), the control unit 14 controls the charging of the battery 5 by the second charging device 204 in the same processing procedure as steps S14 to 16 (step S62 to Step S64), finish the process.

In the second embodiment, although the configuration in which the second charging device 4 performs charging using the charging cable 41 has been described, the configuration is particularly limited as long as it is a charging device that performs wireless communication and performs wired charging. It is not a thing. For example, the second charging device 4 may be an automatic connection charging device (ACD). The automatically connected charging device is extendable from the pole installed so that the tip is located above the ceiling of the vehicle C when the vehicle C stops at a predetermined stopping position, and can extend downward from the tip of the pole And a folded pantograph.

The automatic connection charging device performs wireless communication with the charging communication control device 1 as in the first charging device 3 and transmits and receives various information necessary for charging control.
The automatic connection charging device periodically wirelessly transmits a beacon signal including an identifier, a network name, etc., as in the first charging device 3, and the charging communication control device 1 automatically connects by receiving the beacon signal. An access point associated with the charging device can be detected and wireless communication can be established. As a result of the wireless communication, when the vehicle C corresponds to the automatic connection charging device, the charging communication control device 1 and the charging ECU 2 select the charging by the automatic connection charging device and perform the charging control of the battery 5.
According to the above configuration, when wireless communication with the first charging device 3 is performed, if charging by the automatic connection charging device with high charging efficiency is possible, the charging communication control device 201 wirelessly communicates with the automatic connection charging device. By switching to communication, the battery 5 can be charged by the automatic connection charging device.
