  "textContent": "A method is provided for controlling a vehicle battery system that includes a voltage bus having positive and negative bus rails, at least one battery pack connected to the voltage bus and having positive and negative battery terminals, and a battery disconnect unit. The method includes disconnecting the at least one battery pack from the voltage bus via the battery disconnect unit by performing a first battery disconnect process upon detecting an event condition, by performing a second battery disconnect process upon detecting a high overcurrent condition, and by performing a third battery disconnect process upon detecting a low overcurrent condition. The first battery disconnect process utilizes opening a main pyro fuse, the second battery disconnect process utilizes one or more of thermal fuses, solid-state relays and/or current sensors, and the third battery disconnect process utilizes one or more contactors or solid-state relays.",
