Abstract
A system includes a relay system and a controller. The relay system includes a plurality of relays. The controller is configured to transmit a close signal to a first relay and a second relay of the plurality of relays. The close signal is configured to close the first contact and the second contact of each of the first relay and the second relay. The controller is also configured to measure a first close time between the transmission of the close signal to the first relay and a time when the first relay closes, and to measure a second close time between the transmission of the close signal to the second relay and a time when the second relay closes. The controller is further configured to determine whether an electrical weld exists in the first relay or the second relay, based on the first and second close times.
