Abstract
Disclosed is a control circuit, for use in a solid state battery disconnect and protection system, wherein control circuit includes a high-voltage switch coupled between an electric battery and a DC link capacitor of an electric vehicle, wherein the electric vehicle is powered by the electric battery, and a control block. The control block may by operable to monitor a rate of change and a value of a current on a connection to the high-voltage switch, determine whether the rate of change of the current exceeds a first predetermined threshold and determine whether the value of the current exceeds a second predetermined threshold, and determine an overcurrent fault exists in the case that the first or second predetermined threshold is exceeded.
