    Abstract: An apparatus includes an input module structured to interpret a fuel pressure command indicative of a target fuel pressure within an accumulator and a target fuel injection characteristic, a pump module structured to control a pump assembly to provide fuel to the accumulator to maintain the target fuel pressure within the accumulator, an injector module structured to control a plurality of fuel injectors to inject fuel into an engine based on the target fuel injection characteristic, a pressure module structured to interpret pressure data regarding an actual fuel pressure within the accumulator and to determine a pressure difference between the target fuel pressure and the actual fuel pressure, and a modulation module structured to determine a final fuel injection command responsive to the pressure difference exceeding a first magnitude threshold where the final fuel injection command is based on the pressure difference and the target fuel injection characteristic.

    Abstract: Computer-implemented technology for identifying or determining potentially damaged batteries in an electrical machine system, and for discharging the potentially damaged batteries. Embodiments include determining potentially damaged batteries by monitoring and determining information representative of one or more electrical or mechanical or thermal conditions of the batteries. The conditions may include isolation faults internal to the batteries, isolation faults external to the batteries, liquid or other contamination of the batteries, and other parameters such as out-of-specification temperatures, pressures, voltages and current levels of the batteries. Embodiments include determining whether to discharge potentially damaged batteries based on one or more of the electrical or mechanical or thermal conditions of the damaged batteries. For example, the computer-implemented technology may determine to not discharge a potentially damaged battery if parameters of the battery indicate that possible hazards or risks may be present based on certain parameters of the battery.

    Abstract: The present disclosure provides cab heater systems for electric vehicles. The first system includes a combustion chamber having a combustor inlet, a combustor outlet, and a hydrogen storage fluidly coupled to the combustor inlet configured to supply hydrogen to the combustor for combustion. The second system includes a fluid circulation pump, one or more cabin heat exchangers, a heat transfer tube fluidly connected to the fluid circulation pump and to the one or more cabin heat exchangers, and an insulated tank. The insulated tank includes a tank heat exchanger fluidly connected to the heat transfer tube, a resistance heater, and a phase change material. In the charging mode, the resistance heater provides heat to the phase change material and to the tank heat exchanger, while in the heating mode, the fluid circulation pump provides heat to the tank heat exchanger and to the one or more cabin heat exchangers.
