Abstract

Systems and methods disclosed herein provide for a distributed high-voltage bus for a battery system included in a vehicle. In certain embodiments, the systems and methods disclosed herein provide for a scalable high-voltage bus architecture utilizing a common high-voltage rail for powering vehicle systems and/or modules. Independent contactors may be utilized on the opposite rail to selective power high-voltage branches. In further embodiments, a common rail pre-charge circuit may be utilized allowing for independent pre-charging of HV branches and systems and/or modules coupled to the HV bus.
