Systems and methods for operating a lithium-ion battery high-voltage distribution system architecture are disclosed. A battery pack includes: a plurality of lithium-ion battery cells; a disconnect mechanism operable in an operational position between a battery bus and the plurality of lithium-ion battery cells and a bypass position between the battery bus and a bus-power pass through; and a battery management system. The battery management system is configured to monitor battery pack performance; and responsive to detecting a triggering event in the battery pack performance, cause the disconnect mechanism to be in the bypass position.

Li-Ion battery high voltage distribution system architecture

System and method for allocating load power drawn from multiple batteries for powering propulsion of a vehicle. The system includes: high-energy and high-power batteries respectively designed for optimal production of DC power during high-specific-energy and high-specific-power propulsion; and battery health management systems configured to monitor state of charge and state of health of the batteries and generate battery status signals. The system further includes a propulsion load configured to produce propulsion force using power converted from power generated by at least one of the batteries and a system controller configured to allocate load power drawn from the high-energy and high-power batteries for use by the propulsion load in dependence on a propulsion phase of the vehicle and the battery status.
