The fuel cell system includes at least one fuel cell having a cathode side, an air inlet conduit connected to an inlet end of the cathode side, an air compressor disposed in the air inlet conduit, an air filter arranged to receive air from an ambient environment. The air filter is arranged at an inlet of the air inlet conduit. A a fluid outlet conduit is connected between an outlet end of the cathode side and an inlet side of an expander, and an exhaust conduit is connected to an exhaust side of the expander. The compressed air system comprising: an electrically operable air compressor connectable to the pneumatic device. A controllable valve assembly fluidly connects an air inlet of the compressor to multiple fluid supply positions. The controllable valve assembly selectively directs air from the outlet conduit position, the air inlet conduit position and at least from one of the air inlet conduit position and the position to the compressed air system in response to an operating condition of the vehicle.

摘要： An electric energy dissipating system for a vehicle. The system includes an electric power system configured to be electrically connected to an electric traction motor of the vehicle and configured to receive and store electric power generated by the electric traction motor during braking, a fluid conduit, an air flow producing unit configured to provide a pressurized air flow through the fluid conduit, an electric machine, and a transmission arrangement. The electric machine is configured to be powered by the electric power system so as to drive the air flow producing unit via the transmission arrangement in order to dissipate energy from the electric machine. The transmission arrangement includes a first shaft and a second shaft. The first shaft is driven by the electric machine and the second shaft drives the air flow producing unit. The second shaft rotates at higher speed than the first shaft.

摘要： A method for controlling a power assembly comprising a fuel cell unit and an electric energy storage system. The method includes predicting a power demand for power delivery from the power assembly over a prediction horizon, calculating costs associated with controlling the power assembly according to at least two different control scenarios during the prediction horizon: a first control scenario in which the fuel cell unit is turned off, and a second control scenario in which the fuel cell unit is turned on. For each control scenario, the cost includes at least a cost associated with an expected ability of the power assembly to deliver power according to the predicted power demand, a cost associated with fuel consumption, and a cost associated with fuel cell degradation, comparing the calculated costs of the respective at least two control scenarios to obtain a comparison result, selecting one of the at least two control scenarios based on the comparison result, and controlling the power assembly according to the selected control scenario.

摘要： A system for use in connection with a wheel torque generating component in a heavy-duty vehicle. The system comprises a fluid conduit, a compressor configured to provide a pressurized air flow through the fluid conduit, a mass flow adding arrangement configured to add a fluid to the pressurized air flow in the fluid conduit, thereby increasing the mass flow of the pressurized air flow, and a flow directing device arranged downstream of the mass flow adding arrangement and configured to direct the pressurized air flow, including the added fluid, from the fluid conduit to the wheel torque generating component so as to control the temperature of the wheel torque generating component. The invention also relates to a method for use in connection with a wheel torque generating component in a heavy-duty vehicle.

摘要： A method for controlling a power assembly comprising a fuel cell unit and an electric energy storage system for storing excess electric energy produced by the fuel cell unit. The method comprises predicting a power demand from the power assembly over a prediction time horizon, obtaining a state-of-charge and/or power capability of the electric energy storage system, based on the predicted power demand and the obtained SoC and/or power capability, identifying a time period during which the power assembly is expected to be able to deliver power in accordance with the predicted power demand with the fuel cell unit shut down, or is at least expected to be able to deliver power at a minimum power level determined with respect to the predicted power demand, controlling the power assembly to shut down the fuel cell unit during at least a part of the identified time period in response to the identified time period being larger than a time threshold.
