Description

  The present invention relates to an in-vehicle charging apparatus.

This kind of conventional vehicle-mounted charging device includes a main body case, a charging coil provided in the main body case, and a control unit connected to the charging coil, so as to avoid draining the battery when the engine is stopped. In addition, the power supply to the charging coil is stopped (for example, Patent Document 1 below).

JP 2009-148108 A

The above conventional example was effective as an in-vehicle charging device for an automobile equipped with an engine. However, in an electric vehicle which has been in the limelight in recent years, an engine is not provided, so that appropriate charging cannot be performed. .

  Therefore, an object of the present invention is to enable appropriate charging.

  In order to achieve this object, the present invention provides a main body case, a charging coil provided in the main body case, a control unit connected to the charging coil, and a vehicle charge detection unit connected to the control unit. And a door lock detection unit, wherein the control unit energizes the charging coil in a state where vehicle charge detection is performed by the vehicle charge detection unit and door lock is detected by the door lock detection unit. This is to achieve the intended purpose.

  As described above, the present invention provides a main body case, a charging coil provided in the main body case, a control unit connected to the charging coil, a vehicle charge detection unit connected to the control unit, and a door lock. And a control unit configured to energize the charging coil in a state where vehicle charge detection is performed by the vehicle charge detection unit and a door lock is detected by the door lock detection unit. Therefore, appropriate charging can be performed.

  That is, in the present invention, a vehicle charge detection unit and a door lock detection unit are connected to the control unit, vehicle charge detection is performed by the vehicle charge detection unit, and door lock is detected by the door lock detection unit. In this state, since the charging coil is energized, the mobile device can be appropriately charged at the same time as the vehicle is charged.

  Further, since the door is locked at the time of charging, the portable device being charged can be prevented from being stolen.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
(Embodiment 1)
In FIG. 1, reference numeral 1 denotes an electric vehicle (including not only electricity but also an engine in combination). A driver's seat 3 and a passenger seat 4 are disposed in front of the interior 2 of the vehicle, and a handle 5 is disposed in front of the driver's seat 3. Is arranged.

  Further, a rear seat 6 is arranged behind the vehicle interior 2.

  Further, an in-vehicle charging device 7 is disposed between the driver seat 3 and the passenger seat 4.

  As shown in FIG. 2, the in-vehicle charging device 7 includes a thin box-shaped main body case 8 in which a charging coil 9, a cooling fan 10, and a temperature sensor 11 are provided. If it is placed (not shown), the charging coil 9 can be charged in a non-contact state.

  A power switch 12 and an indicator 13 indicating the state of charge are provided on the outer peripheral portion of the upper surface of the main body case 8.

  Further, the charging coil 9, the cooling fan 10, the temperature sensor 11, the power switch 12, and the indicator 13 are connected to the control unit 14 as shown in FIG.

  Further, as shown in FIG. 3, a vehicle charge detection unit 15, a door lock detection unit 16, and an ACC detection unit 17 are connected to the control unit 14.

  Reference numeral 18 denotes a power source.

  In the above configuration, when it arrives at the charging area of the electric vehicle 1, it takes a long time during the charging.

  Therefore, when charging the portable device using this charging, the portable device is placed on the upper surface of the main body case 8, and then the power switch 12 is turned on (S1 in FIG. 4).

  Then, the control part 14 determines whether the battery of a portable apparatus is a 100% charge state from the electric current which flows into the charging coil 9 (S2 of FIG. 4).

  If the battery of the portable device is 100% charged, the control unit 14 causes the indicator 13 to emit blue light so that the subsequent charging operation is not performed (S3 in FIG. 4).

  If the battery of the portable device is not 100% charged, the control unit 14 confirms (detects) that the door is locked by the door lock detection unit 16 (S4 in FIG. 4). The ACC detection unit 17 confirms that the ACC is not used (S5 in FIG. 4), the vehicle charge detection unit 15 confirms that the vehicle is being charged (S6 in FIG. 4), and the temperature sensor 11 in the main body case 8 If all of these conditions are OK, the charging coil 9 is energized and non-contact charging to the portable device is started (S8 in FIG. 4).

Also, when the door is not locked (S4 in FIG. 4), when ACC is used (
4 (S5 in FIG. 4), when the vehicle is not charged (S6 in FIG. 4), the charging coil 9 is not energized (S9 in FIG. 4).

  Even during charging of the portable device (S7 in FIG. 4), if the temperature in the main body case 8 becomes higher than a predetermined value, the energization to the charging coil 9 is stopped and the cooling fan 10 is driven (FIG. 4). S10).

  Further, when the temperature in the main body case 8 becomes lower than a predetermined value, the cooling fan 10 is stopped (S11 and S12 in FIG. 4).

  Thereafter, the process returns to (S2 in FIG. 4) again, and the charging operation for the portable device is performed.

  As described above, in the present embodiment, the vehicle charge detection unit 15 and the door lock detection unit 16 are connected to the control unit 14, vehicle charge detection is performed by the vehicle charge detection unit 15, and the door lock detection unit is connected. Since the charging coil 9 is energized in a state where the door lock by 16 is detected, the mobile device can be appropriately charged simultaneously with the vehicle charging.

  In other words, it is possible to prevent the power source for driving the vehicle from being inadvertently consumed, and to fully charge the portable device during time-consuming vehicle charging.

  Further, since the door is locked at the time of charging, the portable device being charged can be prevented from being stolen.

  Furthermore, at the time of use as an ACC power supply, inadvertent power consumption during vehicle charging can be suppressed by stopping energization of the charging coil 9.

  As described above, in the present invention, the vehicle charge detection unit and the door lock detection unit are connected to the control unit, vehicle charge detection is performed by the vehicle charge detection unit, and door lock by the door lock detection unit is detected. In this state, the charging coil is energized, so that the mobile device can be appropriately charged simultaneously with the vehicle charging.

  Further, since the door is locked at the time of charging, the portable device being charged can be prevented from being stolen.

  Therefore, utilization as a vehicle-mounted charging device is expected.
