Abstract: A battery system for a vehicle includes a battery tray having a base wall, a plurality of side walls, and a cover that collectively define a receiving zone. A vent includes an inlet and an outlet exposed to the battery receiving zone. A battery is supported by the base wall. A battery electronic controller (BEC) is arranged in the receiving zone and directly connected to the battery.

Abstract: Vehicles and related systems and methods are provided for managing an electrical system. One method involves identifying a current condition associated with an energy source coupled to an electrical grid, identifying a current operating state associated with the vehicle electrical system, determining an adjusted control target for the energy source to increase availability of the energy source based at least in part on the current condition and the current operating state, identifying a control scheme for the energy source based at least in part on the current condition associated with the energy source, and autonomously operating the vehicle electrical system in a manner that is influenced by the adjusted control target in accordance with the identified control scheme.

Abstract: A Multiple Output Dynamically Adjustable Capacity (MODACS) and a method of operation of the MODACS. The MODACS includes a cell, a load in thermal communication with the cell, and a processor. A voltage is applied to a load to generate heat at a cell of the MODACS, wherein the heat affects a temperature of the cell. The processor measures a parameter of the cell in response to the heat and controls an operation of the MODACS based on the parameter of the cell.

Abstract: A vehicle, system and method of operating a battery having a plurality of modules, each module having a plurality of strings. The vehicle includes the battery. A processor operates the plurality of modules in a first phase of a mode of operation, calculates a model-predicted path vector for the first phase based on a time for reducing a difference between states of charges of the plurality of strings, selects between the model-predicted path vector and a default path vector based on an operating parameter of the battery, and switches operation of the plurality of modules from the first phase to a second phase using the selected one of the model-predicted path vector and the default path vector.

Abstract: A vehicle, a Multiple Output Dynamically Adjustable Capacity System (MODACS) of the vehicle and a method of operating the MODACS. The MODACS includes a string and a processor. The string is coupled to a grid. A grid voltage is set to a first set point. The processor is configured to detect a change in a state of health of the string and change the grid voltage from the first set point to a second set point in response to the change in the state of health of the string.

Abstract: Vehicles and related systems and methods are provided for managing an electrical system. One method involves determining an estimated power consumption associated with one or more loads coupled to an electrical grid, obtaining a current voltage associated with the electrical grid, identifying an expected duration associated with an operating state associated with the vehicle electrical system, determining an energy threshold for the expected duration associated with the operating state based at least in part on the current voltage and the estimated power consumption, and autonomously operating the vehicle electrical system in a manner that is influenced by the energy threshold associated with the operating state.
