Abstract
Systems and methods are disclosed for determining a weld state of a contactor (e.g., normal, partially welded, and/or welded states) based on a variety of actuator coil characteristics during actuation. In some embodiments, the disclosed systems and methods may be utilized in connection with determining contactor weld states in a variety of contactor designs. In further embodiments, the disclosed systems and methods may utilize a probability weighted score accounting for contactor design characteristics and information obtained from a reference contactor to identify a weld state associated with a contactor device.
