Each of the circuit portions 2 to 8 described above is held by a wall-mounted charging device main body 10 as shown in FIG. In the following description, the front-rear, up-down, left-right directions are defined in the direction shown in FIG.
The charging device body 10 is formed in a vertically long rectangular parallelepiped shape from a synthetic resin, and is fixed to the wall 200 by an appropriate method. In the lower part of the charging device main body 10, there is provided a storage portion 13 consisting of a recess open to the front side and the lower side at the center in the left-right direction. On the back side of the storage part 13, a holding part 14 to which the connection part 111 of the charging connector CN1 is detachably connected is provided. At the time of non-charging, by connecting the connecting portion 111 of the charging connector CN1 to the holding portion 14, a part of the charging connector CN1 is stored in the storage portion 13 with the leading end side of the charging connector CN1 inserted into the storage portion 13. Has been. That is, the storage unit 13 stores the holding unit 14 in a state where the holding unit 14 faces the outside of the storage unit 13 so that the charging connector CN1 inserted from the outside of the storage unit 13 can be connected to the holding unit 14. The periphery of the holding portion 14 is covered by the inner wall of the storage portion 13.
Further, the charging device body 10 is provided with a first irradiation unit 4 a that irradiates light onto the holding unit 14 disposed in the storage unit 13 at a position above the storage unit 13. The 1st irradiation part 4a consists of a light emitting diode, for example, is arrange | positioned in the back | inner side of the accommodating part 13, and irradiates light toward the opening side from the back | inner side (inner side) of the accommodating part 13. FIG.
Next, the operation of the charging device 1A will be described. When the electric vehicle 100 is not charged, the charging connector CN1 is inserted into the storage unit 13 and held by the holding unit 14. When the charging connector CN1 is not connected to the electric vehicle, the CPLT circuit unit 5a outputs, for example, a DC voltage of about 12V to the communication line L4, and a DC voltage of about 12V is input to the CPLT monitoring circuit unit 5b. . At this time, the control circuit unit 12 determines that the charging connector CN1 is not connected to the vehicle-side connector CN2 based on the detection result of the CPLT monitoring circuit unit 5b, and outputs an off control signal to the relay control circuit unit 3 Then, a lighting control signal is output to the irradiation circuit unit 4. Accordingly, the relay R1 is turned off by the relay control circuit unit 3, the power supply is cut off, and the irradiation circuit unit 4 turns on the first irradiation unit 4a. Thus, since the first irradiating unit 4a irradiates the holding unit 14 with light, the position of the holding unit 14 can be easily understood even when the surroundings are dark, such as at night, and when the charging connector CN1 is removed from the holding unit 14, Therefore, the removal work can be easily performed.
Thereafter, when the user connects the charging connector CN1 removed from the holding unit 14 to the vehicle-side connector CN2, the signal level of the communication line L4 is a constant voltage between the internal resistance on the CPLT circuit unit 5a side and the internal resistance on the charging circuit 101 side. Is switched to a voltage obtained by dividing the voltage (for example, about 9 V). At this time, the control circuit unit 2 determines that the charging connector CN1 is connected to the electric vehicle 100 based on the detection result of the CPLT monitoring circuit unit 5b, and sends a control signal for turning off the first irradiation unit 4a to the irradiation circuit unit. 4 is output. The irradiation circuit unit 4 turns off the first irradiation unit 4a in response to the control signal from the control circuit unit 2, and the illumination of the holding unit 14 is not necessary when the charging connector CN1 is connected to the vehicle-side connector CN2. , Wasteful power consumption can be reduced.
When the charging connector CN1 is connected to the vehicle-side connector CN2, the charging circuit 101 detects that the charging connector CN1 is connected because a predetermined voltage is generated at the terminal to which the communication line L4 is connected. Then, when an operation for starting charging is performed on the electric vehicle 100 side, the charging circuit 101 changes the resistance value of the internal resistance connected to the communication line L4, thereby changing the voltage dividing ratio and the signal of the communication line L4. The level is changed to about 6V, for example. At this time, the control circuit unit 2 determines that charging is possible based on the detection result of the CPLT monitoring circuit unit 5b, and outputs a control signal for turning on the relay R1 to the relay control circuit unit 3. Relay control circuit unit 3 receives a control signal from control circuit unit 2 to turn on relay R 1, power is supplied to electric vehicle 100, and charging circuit 101 starts charging battery 102. Further, the control circuit unit 2 outputs a control signal for turning off the first irradiation unit 4a to the irradiation circuit unit 4, and keeps the first irradiation unit 4a off.
After that, when charging of the electric vehicle 100 is completed, the charging circuit 101 changes the voltage dividing ratio by changing the resistance value of the resistor connected to the communication line L4 in order to notify that charging is impossible, and the communication line L4. For example, the signal level is changed to about 9V. At this time, the control circuit unit 2 determines that charging is not possible based on the detection result of the CPLT monitoring circuit unit 5b, and outputs a control signal for turning off the relay R1 to the relay control circuit unit 3. The relay control circuit unit 3 receives the control signal from the control circuit unit 2 and turns off the relay R1, and the power supply to the electric vehicle 100 is cut off.
When the user disconnects the charging connector CN1 from the vehicle-side connector CN2 after the power supply to the electric vehicle 100 is cut off, the signal level of the communication line L4 is switched to a DC voltage of about 12V. At this time, the control circuit unit 2 determines that the charging connector CN1 is disconnected from the electric vehicle 100 based on the detection result of the CPLT monitoring circuit unit 5b, and sends a control signal for lighting the first irradiation unit 4a to the irradiation circuit unit 4. Output to. The irradiation circuit unit 4 receives the control signal from the control circuit unit 2, turns on the first irradiation unit 4a, and irradiates the holding unit 14 with light from the first irradiation unit 4a. Thus, even when the surroundings are dark, the position of the holding portion 14 can be easily understood, and the holding portion 14 disposed in the storage portion 13 can be easily seen. Therefore, it is easy to connect the charging connector CN1 to the holding portion 14. It can be carried out.
As shown in Table 1, when the voltage level of the CPLT signal is 0V, the power cannot be used, and when it is -12V, the power cannot be used or an error is indicated. If the signal level of the communication line L4 detected by the CPLT monitoring circuit unit 5b is 0V or (−12V), the control circuit unit 2 outputs a control signal for turning off the relay R1 to the relay control circuit unit 3 for irradiation. A control signal for lighting the first irradiation unit 4a is output to the circuit unit 4.
As described above, the charging device 1A for the electric vehicle according to the present embodiment includes the charging cable CB2, the charging control unit (in the present embodiment, including the control circuit unit 2, the relay control circuit unit 3, and the relay R1), the holding Unit 14 and first irradiation unit 4a. The charging cable CB2 has a charging connector CN1 that is detachably connected to the electric vehicle 100. The charging control unit controls charging to the electric vehicle 100 to which the charging connector CN1 is connected. The holding unit 14 holds the charging connector CN1, and the first irradiation unit 4a irradiates the holding unit 14 with light.
Thereby, since light is irradiated to the holding part 14 by the 1st irradiation part 4a, even if the circumference | surroundings are dark, the operation | work which hold | maintains charging connector CN1 in the holding part 14 is easy to do, and workability | operativity improves.
Moreover, 1 A of electric vehicle charging devices of this embodiment are provided with the communication part 5 and the lighting control part (it consists of the control circuit part 2 and the irradiation circuit part 4 in this embodiment). Communication unit 5 communicates with electric vehicle 100 to which charging connector CN1 is connected via charging cable CB2. The lighting control unit controls lighting / extinguishing of the first irradiation unit 4a according to the content of communication performed by the communication unit 5 with the electric vehicle 100.
Thereby, since lighting / extinction of the 1st irradiation part 4a is controlled according to the communication content with the electric vehicle 100, it becomes possible to light the 1st irradiation part 4a at a required timing, and the 1st irradiation part Power consumption can be reduced compared with the case where 4a is always lighted. For example, in the present embodiment, the lighting control unit turns off the first irradiation unit 4a in a state where the charging connector CN1 is connected to the electric vehicle 100, and the lighting control unit is in a state where the charging connector CN1 is not connected to the electric vehicle 100. The first irradiation unit 4a is turned on. When the charging connector CN1 is not connected to the electric vehicle 100, the holding unit 14 is illuminated by the first irradiating unit 4a. Therefore, the charging connector CN1 is held by the holding unit 14 or the charging connector CN1 is removed from the holding unit 14. The work to be taken out is easy and the workability is improved. Further, in the state where the charging connector CN1 is connected to the electric vehicle 100, there is no work to hold the charging connector CN1 on the holding part 14 or to take out the charging connector CN1 from the holding part 14, so the first irradiation part By turning off 4a, wasteful power consumption can be reduced.
The conditions for the lighting control unit to switch on / off the first irradiation unit 4a are not limited to the above-described conditions, and can be appropriately changed depending on the usage pattern and the user's request.
For example, when the user removes the charging connector CN1 from the electric vehicle 100, it is considered that the charging connector CN1 that has been removed a little later is stored in the storage unit 13, so that the first irradiation unit 4a can be turned on after a predetermined timing. it can.
The lighting control unit may turn off the first irradiation unit 4a during charging, for example, and turn on the first irradiation unit 4a at the timing when charging is completed. Further, the lighting control unit turns off the first irradiation unit 4a after a certain time has elapsed after the first irradiation unit 4a is turned on at the timing when the charging connector CN1 is removed from the vehicle or when charging is completed. Alternatively, the first irradiation unit 4a may be turned off at the timing when the user operates the turn-off switch 9 provided in the charging device 1A.
Moreover, in this embodiment, the accommodating part 13 is provided so that the circumference | surroundings of the holding | maintenance part 14 may be covered, and although the 1st irradiation part 4a is irradiating light toward the opening side of the accommodating part 13, as shown in FIG. In addition, the first irradiation unit 4 a may irradiate light toward the inner side of the storage unit 13.
Thus, since the 1st irradiation part 4a is irradiating light toward the inner side (back side) direction of the storage part 13, when a user looks at the storage part 13 from the outer side, from the 1st irradiation part 4a. This makes it difficult for the user to see the light directly and reduces the glare felt by the user.
The control circuit unit 2 controls the lighting / extinction of the first irradiation unit 4a according to the detection input from the illuminance detection sensor circuit unit 7 in addition to the contents of the communication performed by the communication unit 5 with the electric vehicle 100. May be.
That is, the control circuit unit 2 as the lighting control unit may turn off the first irradiation unit 4a regardless of the communication contents when the ambient brightness detected by the illuminance detection sensor circuit unit 7 is brighter than a predetermined threshold. Well, since the illumination of the storage unit 13 is unnecessary when the surroundings are bright, useless power consumption can be reduced by turning off the first irradiation unit 4a.
Note that the lighting control unit may always turn on the first irradiation unit 4a regardless of the contents of communication with the electric vehicle 100, and by always lighting the first irradiation unit 4a, the first irradiation unit 4a It can also have a function.
