Abstract
A battery electric system for a motor vehicle or another electrified system includes a battery pack connected to a direct current voltage bus, and having positive and negative battery terminals, a main pyrotechnic fuse ('pyro fuse'), a high-voltage (HV) component connected to the bus via an HV channel, a current sensing element connected to the HV component on the HV channel, and a control system configured to selectively disconnect the battery pack from the bus by transmitting a voltage signal to the main pyro fuse when a measured current value from the current sensor is indicative of a short-circuit fault. A channel switch may be connected to or integral with the current sensing element, and configured to disconnect the HV component from the bus by opening in response to the measured current value.
