Abstract
Examples described herein provide a method that includes, responsive to determining that a direction of a current relative to a power source of a vehicle is a forward current flowing out of the power source, determining whether the forward current exceeds a forward current threshold for a forward overcurrent detection time period by comparing the current to the forward current threshold. The method further includes, responsive to determining that the direction of the current relative to the power source is a reverse current flowing into the power source, determining whether the reverse current exceeds a reverse current threshold for a reverse overcurrent detection time period shorter than the forward overcurrent detection time period by comparing the current to the reverse current threshold. The method further includes controlling, using a gate driver, at least one switch associated with the power source to inhibit the current.
