| description | A malfunction of a wireless power transmission system is detected without requiring installation of sensors in power transmitting coils. A malfunction diagnosis apparatus (300) for diagnosing a malfunction of a wireless power transmission system including a plurality of power transmission units (100) and a vehicle (200). Each of the power transmission units is equipped with a plurality of power transmitting coils (112). The vehicle is equipped with a power receiving coil (212) which works to receive electric power transferred from each of the power transmission units. The malfunction diagnosis apparatus includes an information receiver (310) which receives power transmission unit information outputted from each of the power transmission units and the vehicle power receiving information outputted from the vehicle, and a diagnostic unit (35) which analyzes present position information about the vehicle and present position information-obtained time information about the vehicle which are included in each of pieces of vehicle power receiving information, as received by the information receiver, to identify target power transmission units that are some or all of the power transmission units which have transferred the electric power to the vehicle. The diagnostic unit works to compare between transmitted power information included in pieces of the power transmission unit information about the target power transmission units to diagnose a state of transmission of the electric power from each of the power transmission units. |
