Abstract
This application is directed to protecting a battery or battery by a battery protection system including two distinct protection integrated circuits (PICs). The two PICs are configured to determine whether a drive current of the battery is at fault and generate distinct switching signals indicating whether the drive current of the battery is at fault. The two PICs are interchangeable with each other. The battery protection system further includes control logic and two switching components. The control logic is configured to combine the switching signals provided by the two PICs to provide a combined switching signal. Each switching component is coupled to the control logic and configured to control a current path of charging and discharging the battery based on the combined switching signal.
