Abstract
A malfunction diagnosis apparatus diagnoses a malfunction of a wireless power transmission system including a plurality of power transmission units and a vehicle. Each unit is equipped with a plurality of power transmitting coils. The vehicle is equipped with a power receiving coil which works to receive electric power transferred from each unit. The apparatus includes an information receiver which receives power transmission unit information outputted from each unit and the power receiving information outputted from the vehicle, and a diagnostic unit which analyzes present position and time information about the vehicle which are included in the vehicle power receiving information, to identify target power transmission units that have transferred the electric power to the vehicle. The diagnostic unit works to compare between transmitted power information about the target power transmission units to diagnose a state of transmission of the electric power from each unit.
