Abstract
Systems and methods are provided for releasing welded-shut contactors of a contactor system. An exemplary contactor system may include a contactor and a controller. The controller may be programmed to command a vibration across portions of the contactor as part of a weld release control strategy when the contactor is welded closed. The vibration may be achieved by repeatedly alternating between energizing and de-energizing a coil of the contactor in order to mechanically shock/vibrate a welded contact of the contactor.
