Distributed vehicle battery high-voltage bus systems and methods

A method comprising:

• opening a primary contactor, the primary contactor being configured to selectively couple a first terminal of a vehicle battery system to a common primary rail;
• closing a pre-charging contactor included in a pre-charging circuit to couple the first terminal to the common primary rail across the pre-charging circuit, the pre-charging circuit disposed in parallel with the primary contactor comprising the pre-charging contactor and the pre-charging resistor disposed in series;
• closing a branch contactor of a plurality of branch contactors to selectively couple an associated vehicle module of a plurality of vehicle modules to a secondary rail coupled to second terminal of the vehicle battery system;
• and
• wherein the pre-charging circuit is configured to perform independent pre-charging operations for branches associated with each of the plurality of branch contactors by selectively actuating the primary contactor, the pre-charging contactor, and the plurality of branch contactors.
