DISTRIBUTED VEHICLE BATTERY HIGH-VOLTAGE BUS SYSTEMS AND METHODS

摘要

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.

主权项

1. A system comprising:
a vehicle battery system; a primary contactor configured to selectively couple a positive terminal of the vehicle battery system to a common primary rail; a plurality of vehicle modules coupled to the common primary rail; and a plurality of branch contactors, each branch contactor being associated with at least one vehicle module of the plurality of vehicle modules and being configured to selectively couple an associated vehicle module to a secondary rail coupled to a negative terminal of the vehicle battery system.
