摘要

In one implementation, a method is provided for contactor monitoring and control in electric vehicle supply equipment, which includes updating an open error count and a close error count based on a detected condition of the contactor. The method also includes determining a detected state of the contactor by comparing the open error count and the close error count to maximum and minimum values. The method further includes performing at least one of controlling the state of the contactor based on the determined contactor state, or providing a visual indicator based on the determined contactor state.
