Abstract

A vehicle-mounted charging device which begins to charge at an appropriate timing when driving a vehicle. A driver sets the travel distance at which charging begins while charging coil (10) and charging coil (13) are magnetically coupled, then a charge control unit (12) drives a drive circuit (11) once the travel distance of the vehicle becomes equal to or greater than the set value. The drive circuit (11) excites charging coil (10) and supplies power from charging coil (10) by changing the magnetic flux generated by charging coil (10). As a consequence, a portable device (7) begins to be charged.

Claims

1. A vehicle-mounted charging apparatus comprising:

a charging coil that is used for charging a mobile device;

a drive circuit that is connected to the charging coil and that is driven to supply power to the mobile device via the charging coil;

a charge control section that is connected to the drive circuit and that controls a timing to start driving the drive circuit; and

a charge-start setting section that is connected to the charge control section and that sets a distance at which charging starts, wherein

the charge control section drives the drive circuit after a vehicle runs a running distance in a state where the charging coil and the mobile device are magnetically coupled, the running distance being set by the charge-start setting section.

2. The vehicle-mounted charging apparatus according to claim 1, wherein the charge control section is connected to a vehicle electronic control unit (ECU) that informs a vehicle running distance.

3. The vehicle-mounted charging apparatus according to claim 1, wherein the charge-start setting section includes a touch switch of a display connected to the charge control section.

4. The vehicle-mounted charging apparatus according to claim 3, wherein the charge control section is connected to a vehicle electronic control unit (ECU) via the display.

5. A vehicle comprising the vehicle-mounted charging apparatus according to claim 1.
