1. An apparatus for determining an abnormal status of a wireless power transmission coil, the apparatus comprising:
- an input-current sensor configured to detect an input current, the input-current sensor being provided at an input side of a power transmission coil;
an output-current sensor configured to detect an output current, the output-current sensor being provided at an output side of the transmission coil; and
a controller unit configured to determine that a disconnection occurs in the transmission coil when the input current is less than a disconnection input threshold value and the output current is less than a disconnection output threshold value, and determines that a short circuit occurs in the transmission coil when the input current is greater than a short-circuit input threshold value and the output current is less than a short-circuit output threshold value.

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.
