A method detects a shorted charging cable of an electric vehicle charging station. A charging cable of the electric vehicle charging station is determined to not be connected to an electric vehicle. An impedance test may then be performed between conductors of the charging cable while not connected to an electric vehicle. A contactor between a source of electrical power and the conductors is prevented from closing, in response to detecting a short between the conductors, and a warning signal is output. The impedance test is disabled in response to receiving a signal indicating that the charging cable has become connected to an electric vehicle, so as to not interfere with normal charging. In this manner, by detecting a short circuit in the charging cable before the contactors are closed, the contactor's contacts are prevented from becoming welded closed by a short circuit in the charging cable.
