Abstract:
Provided is an apparatus for determining an abnormal status of a wireless power transmission coil, the apparatus including an input-current sensor configured to detect an input current and provided at an input side of a power transmission coil, an output-current sensor configured to detect an output current and provided at an output side of the transmission coil, and a controller configured to compare each of the input current and the output current with a predetermined threshold value corresponding thereto to determine whether a disconnection or a short circuit occurs in the transmission coil.
