Abstract: A power system includes a battery charge path and capacitor charge path arranged in parallel. During an inrush event, a current limiting element restricts current flow along the battery charge path to relieve battery stress. During the inrush event, current flow between the battery and load along a bypass path is also prevented by a switch element. Under steady state charging conditions, the resistance of the current limiting element decreases, thus increasing current flow between the battery and load along the battery charge path. During steady state conditions, a switch circuit controls operation of the switch element to also allow current flow between the battery and load along the bypass path. The change in the resistance of the current limiting element and/or actuation of the switch element by the switch circuit are optionally based on changes in temperature, and are passively effectuated without requiring an external control input signal.
