Abstract: An example method includes receiving, from one or more sensors of a battery module, sensor information indicative of a health status of the battery module; determining, based on sensor information, battery health parameters of the battery module; determining, based on the battery health parameters, a target state-of-charge (SoC) indicating a target battery capacity to which the battery module is to be charged; determining an end-of-charge voltage (EOCV) to be attained at an end of charging the battery module to achieve the target SoC; and commanding a battery charger to charge the battery module until the EOCV is achieved.

Abstract: 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 eon figured 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.

Abstract: 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.

Abstract: A reconfigurable battery system is disclosed. The reconfigurable battery system comprises a reconfigurable battery cell array, a controller, and a bus switch. The battery cell array is configured to operate in a first discharge mode, a second discharge mode, or a charge mode. The battery cell array includes a plurality of battery cells arranged as at least a first column of battery cells between a second battery terminal and a first battery terminal and a switch between each battery cell within the first column of battery cells. The bus switch is in signal communication with the battery cell array at the first battery terminal and is configured to select between electrically connecting the first battery terminal to a normal voltage bus or a high-voltage bus.
