FIG. 3 is a first diagram showing a processing flow of the charging system.
FIG. 4 is a second diagram showing a processing flow of the charging system.
Next, the processing flow of the charging system will be described in order.
First, the user who drives the vehicle 20 checks the indicator of the charge capacity of the secondary battery 3 provided in the front of the driver's seat of the vehicle 20 or the like. When the charging capacity of the secondary battery 3 is small, the user drives the vehicle 20 to the charging station provided with the charging device 1 and stops the vehicle 20 at a predetermined position. At this time, by aligning the tire of the vehicle 20 with the vehicle stop 30, the position of the charging mechanism 10 or the power supply mechanism 5 so that the power supply mechanism 5 provided in the vehicle 20 can be opposed to the vicinity of the charging mechanism 10. It is assumed that the mounting position in the vehicle 20 is set in advance.

  Further, the user inputs a target charge amount to the vehicle-mounted device 2. For example, the user operates a user interface provided in the vehicle-mounted device 2 and designates a target charge amount after completion of charging such as full (100%), 80%, 60%, and the like. The target charge amount may be a specific value of ~ KW (kilowatt). Further, the user inputs the charge type to the vehicle-mounted device 2. For example, the user operates the user interface of the vehicle-mounted device 2 and selects quick charging or normal charging in which charging energy is standardized. The information operated by the user is input by the input unit 26 and output to the charge control unit 22. The charge control unit 22 records the input target charge amount in the storage unit 25 and notifies the charge start request unit 23 of the charge type. Then, the charge start request unit 23 transmits a charge start request signal including the charge type to the charging device 1 via the communication unit 21 (step S101). The charge start request signal is transmitted from the antenna of the vehicle-mounted device 2 to the antenna 18 of the charging device 1 by DSRC communication.

  Next, in the charging device 1, the communication unit 11 receives a charge start request signal (step S102). Then, the charge control unit 13 temporarily records the charge type included in the charge start request signal in the storage unit 17. The charge control unit 13 outputs a charge type to the charge availability determination unit 15 and requests a charge availability determination. The chargeability determination unit 15 compares the charge type information that can be charged by the charging device 1 stored in the storage unit 17 with the input charge type information, and performs chargeability determination (step S103). Then, if the charge type information that can be charged by the charging device 1 stored in the storage unit 17 matches the input charge type information, the charge enable / disable determining unit 15 displays information indicating that charge is possible. 13 to output. On the other hand, if the charge type information stored in the storage unit 17 and the input charge type information do not coincide with each other and the charge type determination unit 15 does not match, the charge control unit 13 displays information indicating that charging is not possible. Output to. The charge control unit 13 transmits a compatibility confirmation information request signal to the vehicle-mounted device 2 via the communication unit 11 when charging permission is input (step S104). In addition, when the charge control part 13 inputs the charge impossibility, the charge control part of the onboard equipment 2 which transmitted the signal to the effect that the charge by the charge classification input by the user cannot be performed is transmitted to the onboard equipment 2. 22 displays via the user interface that charging cannot be performed according to the input charging type and re-input by changing the charging type, or to cancel charging.

  When receiving the compatibility confirmation information request signal (step S105), the charging control unit 22 of the vehicle-mounted device 2 outputs the compatibility confirmation information request signal to the charge control device 4. Then, the charging control device 4 outputs the compatibility confirmation information of the secondary battery 3 to the vehicle-mounted device 2 in response to the reception of the compatibility confirmation information request signal. The compatibility confirmation information includes a voltage value that can be allowed by the power feeding mechanism 5 of the vehicle 20, an upper limit value of the current value (allowable input upper limit value), and a current charging capacity of the secondary battery 3. And the charge control part 22 of the onboard equipment 2 transmits the information for compatibility confirmation to the charging device 1 via the communication part 21 (step S106).

  Next, the charging control unit 13 of the charging device 1 inputs compatibility confirmation information via the communication unit 11, and performs compatibility confirmation between the charging mechanism 10 and the power feeding mechanism 5 using the compatibility confirmation information ( Step S107). Then, as a result of the compatibility check, the charge control unit 13 confirms the compatibility, and transmits a preparation completion signal to the vehicle-mounted device 2 via the communication unit 11 (step S111). In addition, when it is confirmed that there is no compatibility as a result of the compatibility check, the charging control unit 13 transmits a signal indicating that charging cannot be performed according to the charging type input by the user to the in-vehicle device 2 side, and receives the signal. The charging control unit 22 displays, via the user interface, a message indicating that charging cannot be performed according to the input charging type, and re-input by changing the charging type, or stopping of charging is selected. An error signal is transmitted to the vehicle-mounted device 2 via the communication unit 11.

  The specific processing of the compatibility check in the charging device 1 is that the charging control unit 13 includes the allowable input upper limit value on the power feeding mechanism 5 side of the vehicle 20 included in the compatibility checking information, and the charging mechanism of the charging device 1. The supply output upper limit value on the 10 side is compared. If the allowable input upper limit value is greater than or equal to the supply output upper limit value, the charging control unit 13 determines that there is compatibility, and otherwise determines that there is no compatibility.

  The charging control unit 22 of the vehicle-mounted device 2 that has input the preparation completion signal via the communication unit 11 starts the position adjustment mode of the charging mechanism 10 (step S112). In the position adjustment, the charging control unit 22 of the vehicle-mounted device 2 transmits a first adjusted charging start signal to the charging device 1 via the communication unit 21 (step S113). The adjusted charging start signal includes an output value of charging energy and an adjusted charging time. Then, the charging control unit 13 of the charging device 1 supplies power to the charging mechanism 10 via the power line 31 (step S114). At this time, the charging control unit 13 determines the voltage value of the charging mechanism 10 via the control line 32 so that the output value of the charging energy from the charging mechanism 10 becomes the output value of the charging energy included in the received adjusted charging start signal. And control the current value. In addition, the charging control unit 13 of the charging device 1 controls the charging mechanism 10 via the control line 32 so as to output the charging energy during the adjusted charging time included in the received adjusted charging start signal. When the adjustment charging time has elapsed, the charging control unit 13 performs control to stop the output of charging energy from the charging mechanism 10. And the charge control part 13 transmits the 1st adjustment charge completion signal to the onboard equipment 2 via the communication part 11 (step S115). Note that the position of the charging mechanism 10 during the first adjustment charging is referred to as a reference position, and the charging control unit 13 records the reference position in the storage unit 17.

  On the other hand, in the vehicle-mounted device 2, immediately after transmitting the adjustment charge start signal, the battery capacity before the first adjustment charge is acquired from the charge control device 4 and recorded in the storage unit 25. And the charging control part 22 of the onboard equipment 2 will receive the battery capacity after the 1st adjustment charge completion of the secondary battery 3 from the charge control apparatus 4, if the 1st adjustment charging completion signal is received via the communication part 21. Obtained and compared with the battery capacity before the first adjustment charge, the amount of charge charged in the first adjustment charge is calculated (step S116). And the charge control part 22 transmits the adjustment charge amount information containing the charge amount charged in the 1st adjustment charge to the charging device 1 via the communication part 21 (step S117).

  Then, the charging control unit 13 of the charging device 1 inputs the adjusted charging amount information via the communication unit 11 and records the charging amount charged in the first adjusted charging included in the information in the storage unit 17. Then, based on an instruction from the charging control unit 13, the charging mechanism drive control unit 14 performs control to move the position of the charging mechanism 10 from the reference position by a distance ΔL1 in a predetermined direction via the control line 32 (step S118). ) And the movement information (direction and distance) is recorded in the storage unit 17. Thereby, the position of the charging mechanism 10 moves, for example, by a distance ΔL1 in front of the vehicle 20 (predetermined direction). And the charge control part 13 of the charging device 1 transmits a position adjustment completion signal to the vehicle equipment 2 via the communication part 11 (step S119). The movement (direction and distance) from the reference position may be initially set or may be set to be selected at random. In addition, a marking or the like indicating the installation position of the power feeding mechanism 5 is provided on the vehicle 20 side, and a sensor or the like for detecting the position of the marking or the like is provided on the charging mechanism 10 side. The position information is transmitted to the charging control unit 13 via the control line 32, and the charging control unit 13 performs control to move the charging mechanism 10 in a direction in which the relative distance between the marking and the sensor is close to each other. You may keep it.

  Next, when the charging control unit 22 of the vehicle-mounted device 2 inputs the position adjustment completion signal via the communication unit 21, the second adjustment charging start signal is transmitted to the charging device 1 via the communication unit 21 (step S120). ). The adjusted charging start signal includes the output value of charging energy and the adjusted charging time, which are the same values as in the first time. Then, the charging control unit 13 of the charging device 1 supplies power to the charging mechanism 10 via the power line 31 (step S121). At this time, the charging control unit 13 determines the voltage value of the charging mechanism 10 via the control line 32 so that the output value of the charging energy from the charging mechanism 10 becomes the output value of the charging energy included in the received adjusted charging start signal. And control the current value. Further, the charging control unit 13 of the charging device 1 controls the charging mechanism 10 via the control line 32 so as to output the adjusted charging time and the charging energy included in the received adjusted charging start signal. When the adjustment charging time has elapsed, the charging control unit 13 performs control to stop the output of charging energy from the charging mechanism 10. And the charge control part 13 transmits the 2nd adjustment charge completion signal to the vehicle equipment 2 via the communication part 11 (step S122).

  On the other hand, in the vehicle-mounted device 2, immediately after transmitting the second adjustment charge start signal, the battery capacity of the secondary battery 3 before the second adjustment charge is acquired from the charge control device 4 and recorded in the storage unit 25. Keep it. And the charging control part 22 of the onboard equipment 2 will receive the battery capacity after the 2nd adjustment charge of the secondary battery 3 from the charge control apparatus 4, if the adjustment charge completion signal of the 2nd time is received via the communication part 21. Obtaining and calculating the amount of charge charged in the second adjustment charge compared to the battery capacity before the second adjustment charge (step S123). And the charge control part 22 transmits the adjustment charge amount information containing the charge amount charged in the 2nd adjustment charge to the charging device 1 via the communication part 21 (step S124).

  Then, the charging control unit 13 of the charging apparatus 1 inputs the adjusted charging amount information via the communication unit 11 and records the charging amount charged in the second adjusted charging included in the information in the storage unit 17. Then, the charge control unit 13 compares the charge amount charged in the first adjustment charge with the charge amount charged in the second adjustment charge, and determines whether the charge amount increases or decreases. . Then, the charging control unit 13 determines the adjustment position of the charging mechanism 10 according to whether the charging amount has increased or decreased. For example, when the charging amount increases in the first to second adjustment charging, the charging control unit 13 moves the position moved further by ΔL1 in the predetermined direction (forward) similar to step S118 to the next. When the charging amount is reduced in the first to second adjustment charging, the charging control unit 13 determines that the adjustment position, or only ΔL2 (ΔL1 × 2) in the opposite direction (backward) to step S118. The moved position may be determined as the next adjustment position, or may be moved in the opposite direction, and is not particularly limited.

  Then, based on the instruction of the charging control unit 13, the charging mechanism drive control unit 14 performs control to move the position of the charging mechanism 10 to the next adjustment position via the control line 32 (step S125). As a result, the position of the charging mechanism 10 is, for example, a position that is moved by a distance ΔL1 from the reference position to the rear (the other direction) of the vehicle 20 when the amount of charge decreases in the first to second adjustment charging. The movement is controlled to ΔL2 rearward from the previous position. And the charge control part 13 of the charging device 1 transmits a position adjustment completion signal to the vehicle equipment 2 via the communication part 11 (step S126).

  Next, when the charging control unit 22 of the vehicle-mounted device 2 inputs a position adjustment completion signal via the communication unit 21, a third adjustment charging start signal is transmitted to the charging device 1 via the communication unit 21 (step S127). ). The adjusted charging start signal includes the output value of charging energy and the adjusted charging time, which are the same values as those in the first and second times. Then, the charging control unit 13 of the charging device 1 supplies power to the charging mechanism 10 via the power line 31 (step S128). At this time, the charging control unit 13 determines the voltage value of the charging mechanism 10 via the control line 32 so that the output value of the charging energy from the charging mechanism 10 becomes the output value of the charging energy included in the received adjusted charging start signal. And control the current value. Further, the charging control unit 13 of the charging device 1 controls the charging mechanism 10 via the control line 32 so as to output the adjusted charging time and the charging energy included in the received adjusted charging start signal. When the adjustment charging time has elapsed, the charging control unit 13 performs control to stop the output of charging energy from the charging mechanism 10. And the charge control part 13 transmits the adjustment charge completion signal of the 3rd time to the onboard equipment 2 via the communication part 11 (step S129).

  On the other hand, in the vehicle-mounted device 2, immediately after transmitting the third adjustment charge start signal, the battery capacity of the secondary battery 3 before the third adjustment charge is acquired from the charge control device 4 and recorded in the storage unit 25. Keep it. When the charging control unit 22 of the vehicle-mounted device 2 receives the third adjustment charging completion signal via the communication unit 21, the charging capacity of the secondary battery 3 after the third adjustment charging is determined from the charging control device 4. The charge amount acquired and charged by the third adjustment charge is calculated by comparison with the battery capacity before the third adjustment charge (step S130). And the charge control part 22 transmits the adjustment charge amount information containing the charge amount charged in the 3rd adjustment charge to the charging device 1 via the communication part 21 (step S131).

  Then, the charging control unit 13 of the charging apparatus 1 inputs the adjusted charging amount information via the communication unit 11 and records the charging amount charged in the third adjusted charging included in the information in the storage unit 17. And the charge control part 13 compares each charge amount charged in the 1st-3rd adjustment charge, and specifies the largest charge amount. Then, the charging control unit 13 adjusts the adjustment position of the charging mechanism 10 when calculating the largest amount of charging (information on the position of the charging mechanism recorded in the storage unit 17 at the first, second, and third adjustment chargings). Among them, the position information when the battery is charged the most) is determined as the confirmed position (step S132). Then, the charging control unit 13 controls the position of the charging mechanism 10 based on the confirmed position. As a result, the charging mechanism 10 moves to the confirmed position. In the above-described processing, the adjustment charging is performed three times, and the adjustment position at the time of the adjustment charging where the largest amount of charge is charged is determined as the fixed position of the charging mechanism 10, but the adjustment charging is performed more times. The final position may be determined. In addition, the adjustment position determination process of the charging mechanism 10 in each adjustment charging may be any process as long as the charging mechanism 10 can be moved to a position where charging can be efficiently performed using the charging energy.

  In addition, the charging control unit 13 determines whether the charging amount with the highest value among the charging amounts charged in the first to third adjustment chargings is equal to or higher than a predetermined supply efficiency threshold, and is equal to or higher than the predetermined supply efficiency threshold. Only in some cases, the adjustment position of the charging mechanism 10 when the charge amount is calculated may be determined as the confirmed position. For example, “charge amount ÷ adjustment charge time” is calculated to calculate the charge amount per unit time. If the charge amount per unit time is equal to or greater than a predetermined supply efficiency threshold value (charge amount threshold value per unit time), the adjustment position of the charging mechanism 10 when the charge amount is calculated is determined as the confirmed position. . In addition, when the charge amount with the highest value is not equal to or greater than the predetermined supply efficiency threshold, the charge control unit 13 transmits a vehicle stop position adjustment request to the vehicle-mounted device 2 via the communication unit 11. When receiving the vehicle stop position adjustment request, the vehicle-mounted device 2 displays an instruction screen for adjusting the vehicle stop position on the display unit or the like. In this case, the user adjusts the position where the vehicle 20 is driven and stopped.

  When the charging control unit 13 of the charging device 1 determines the confirmed position of the charging mechanism 10, it next transmits a main charging start signal to the vehicle-mounted device 2 via the communication unit 11 (step S133). Then, the charging control unit 22 inputs the main charging start signal via the communication unit 21 of the vehicle-mounted device 2, and transmits a signal indicating the main charging start OK to the charging device 1 via the communication unit 21 (step S134). Then, the charging control unit 13 of the charging device 1 outputs the charging energy from the charging mechanism 10 to the charging mechanism 10 via the control line 32. At this time, the charge control unit 13 reads the charge type temporarily recorded in the storage unit 17 based on the charge start request signal, and controls the output of the charge energy based on the charge type. For example, if the charge type is rapid charge and the charge capacity (remaining amount) of the secondary battery 3 is low, the output of the charge energy is controlled to the maximum. Then, the charging mechanism 10 converts the power supplied from the power line 31 into charging energy and outputs it to the power feeding mechanism 5 (step S135).

  The charge control unit 22 of the vehicle-mounted device 2 inputs the main charge start signal in the above-described step S133 and transmits a signal indicating the main charge start OK in step S134, and then transmits the signal indicating the main charge start OK to the charge control device 4 at predetermined time intervals. A charge amount request is transmitted (step S136). When the charge amount input from the charge control device 4 as a response to the charge amount request is less than a predetermined value (for example, less than 90%) of the charge capacity of the secondary battery 3, the charge control unit 22 A voltage is repeatedly output to the charging control unit 13 of the charging device 1 so as to hold the voltage value and the current value. The charge control unit 22 gradually reduces the charge energy when the charge amount input from the charge control device 4 as a response to the charge amount request becomes equal to or greater than a predetermined value of the charge capacity of the secondary battery 3. Then, a signal is output to the charging control unit 13 of the charging device 1 so as to charge to the target charging amount. When the charge amount of the secondary battery 3 being charged reaches the target charge amount, the charge control unit 22 transmits a charge stop request to the charging device 1 via the communication unit 21 (step S138).
