Abstract: A proximity detection circuit suitable for use with an on-board vehicle charger, such as but not limited to the type of chargers used within hybrid and electric vehicles, to facilitate current conservation during period of time when it is unnecessary or otherwise undesirable. The on-board charger can test for connection of a cordset or other electrical connection used to connect the on-board charger to a charging station or other current source. The on-board charger can be used to detect two different cordsets or vehicles using different charging circuitries.

Abstract: In at least one embodiment an apparatus for diagnosing electronics in an insulation resistance monitoring system is provided. The apparatus includes a controller for being electrically coupled to a plurality of electronics including a plurality of switches that are electrically coupled to a positive branch and to a negative branch in a high voltage network and a low voltage network. The plurality of electronics is configured to perform insulation resistance monitoring in a vehicle. The controller is further configured to at least one of activate and deactivate any number of the plurality of switches to determine an overall voltage of the positive branch and the negative branch. The controller is further configured to detect a fault in at least one of the positive branch and the negative branch that corresponds to a failure of any one of the plurality of electronics based on the overall voltage.
