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 low-voltage mitigation and recovery system includes: an auxiliary power module that converts an output voltage of a power source of a vehicle to a charging voltage, the power source provides power to power a propulsion system of the vehicle; a contactor that supplies power from the power source to the auxiliary power module; a first control module that controls states of the auxiliary power module and the contactor. A second control module is integrated within a MODACS, monitors parameters of blocks of cells of the MODACS, and, based on at least one of the parameters: configures a switch network of the MODACS to disconnect a first set of blocks of the MODACS from loads and to connect or maintain connection of a second set of blocks of the MODACS to selected ones of the loads; and wakes up the first control module to jump start and recover the MODACS.

Abstract: A battery system for a vehicle includes: first and second positive terminals and a negative terminal; switches; at least three strings of battery cells, each of the strings configured to, at different times be: connected to the first positive terminal via first ones of the switches; connected to the second positive terminal via second ones of the switches; and disconnected from both of the first and second positive terminals; and a switch control module configured to: identify one of a short circuit and an over voltage condition in a first voltage bus; when the one of the short circuit and the over voltage condition is identified, identify N of the strings of battery cells with the N lowest state of health values; and control switching of the switches and connect the identified N strings of battery cells to the first voltage bus.

Abstract: A battery system for a vehicle includes: a first positive terminal, a second positive terminal, and a negative terminal; switches; at least two battery modules each including at least three strings of battery cells that are configured to, at different times be: connected in series and to the first positive terminal via first ones of the switches; connected in parallel and to the second positive terminal via second ones of the switches; and disconnected from both of the first and second positive terminals; and a switch control module configured to, based on a derated state of the vehicle, adjust at least one of an upper limit for charging of the battery strings and a lower limit for discharging of the battery strings.

Abstract: A system and apparatus for improving ventilation of a fluid system is disclosed herein. An apparatus for improving ventilation of a fluid storage tank includes a hollow member having a sidewall and an opening formed in the sidewall and an air-permeable membrane extending at least partially across the opening. The membrane permits the passage of air across the membrane and restricts the passage of fluid across the membrane.

Abstract: A exhaust fluid tank includes a base having an inner base surface and an outer surface; a first end wall, a second end wall, a first side wall, and a second side wall, each extending from the base and each wall having an inner surface and an outer surface. A first heating element is disposed within the exhaust fluid tank.
