Abstract
Methods and apparatuses for failure mode detection in a contactor are disclosed. In a particular embodiment, a method for failure mode detection in a contactor includes maintaining the contactor command signal in the open state; connecting the contactor to a voltage supply that supplies a first predetermined voltage amount to the contactor; measuring a first amount of time for a magnitude of a coil current of the coil to exceed a first predetermined current threshold; determining whether the first amount of time exceeds a first predetermined time threshold; responsive to determining that the first amount of time does not exceed the first predetermined time threshold, determining that the contactor is in the open state; and responsive to determining that the first amount of time exceeds the first predetermined time threshold, determining that the contactor is in the closed state.
