Abstract

A vehicle-mounted charger for executing contactless charging is provided with: a control unit that controls power to be fed to a primary coil; a position detection unit that detects the relationship in the positions of the primary coil and a secondary coil of the device to be charged, such as a cellular phone; and a notification unit that executes notification to users. The control unit executes control so as to obtain the position relationship between the primary coil and the secondary coil that was detected by the position detection unit, in a state wherein power is not fed to the primary coil, and make the notification unit notify the user about the position relationship.

Description

technical field [0001] The invention relates to a vehicle charger for wireless charging. Background technique [0002] Currently, as the performance of mobile phones increases, the power consumption of mobile phones also increases, and it is also necessary to charge such mobile phones in vehicles. In addition, practical use of wireless charging using electromagnetic induction has progressed. [0003] In the field of wireless chargers, a known technique is to detect a relative position between a primary coil for power transmission and a secondary coil for power reception by comparing a voltage generated in the secondary coil with a reference voltage ( For example, see Patent Document 1). [0004] reference list [0005] patent documents [0006] Patent Document 1: JP-A-2008-206295 Contents of the invention [0007] technical problem [0008] In the case where the wireless charger described above is mounted on a vehicle, when the charging coil serving as the primary co...
