Abstract: Systems and methods for cooling an electric energy storage device of an electric vehicle are described. In one example, a temperature of a traction battery is predicted and an opportunity assessment is generated, where the opportunity assessment is based on the temperature of the traction battery being predicted to exceed a threshold temperature, where the temperature of the traction battery is predicted prior to a traction battery DC fast charging event, and where the temperature of the traction battery based on time and a segment of a travel route.

Abstract: A fuel cell system has a fuel cell stack including a plurality of fuel cells and an anode injector system, and a controller programmed. The controller, responsive to an amplitude of cyclic changes in voltage of at least some of the fuel cells exceeding a threshold, a frequency of the cyclic changes being within a predetermined range of a frequency associated with the anode injector system, and the voltage being less than a predetermined value, disables the fuel cell stack.

Abstract: A system, such as for a fuel cell electric vehicle, includes a fuel cell stack (FCS) and a controller. The FCS is configured to provide, such as for vehicle propulsion, a stack power commensurate with a stack power request. The stack power is a product of a stack current of the FCS and a stack voltage of the FCS. The controller is configured to, upon the stack voltage meeting a predetermined threshold, control the FCS to increase the stack current to cause the FCS to provide an increased stack power commensurate with an increased stack power request.

Abstract: A vehicle includes a fuel cell having an air inlet port and an air outlet port and an air supply system having a compressor connected in fluid communication with the inlet port and a throttle valve connected in fluid communication with the outlet port. A controller is programmed to change a position of the throttle valve based on a target mass air flow, a measured mass air flow, a measured pressure, and the position of the throttle valve.

Abstract: A system includes a fuel cell stack (FCS) and a controller. The controller adjusts a stack current of the FCS to a desired amount to cause the FCS to provide a power commensurate with a power request. The controller employs a stack power model of the FCS in adjusting the stack current.

Abstract: A vehicle includes a fuel cell, an inlet valve, a purge valve, and a controller. The fuel cell has an anode side configured to receive hydrogen. The inlet valve is configured to open to deliver the hydrogen to the anode side. The purge valve is configured to open to purge water and nitrogen from the anode side. The controller is programmed to, operate the inlet valve to inject hydrogen into the anode side via opening the inlet valve followed by closing the inlet valve. The controller is further programmed to, in response to a concentration of the hydrogen in the anode side being less than threshold, open the purge valve to purge water and nitrogen from the anode side.

Abstract: The disclosure relates to a vehicle with a traction battery and a fuel cell system, and a controller programmed to purge the fuel cell system by flowing air through it to remove moisture from the fuel cell system. The controller is configured to initiate the purge based on a distance of the vehicle from a destination, a state of charge of the traction battery, and ambient temperature conditions at the destination. The freeze preparation process can be initiated when the vehicle is approaching its destination and can be predicted using connectivity and communication with off-board sources.

Abstract: A vehicle includes a fuel cell stack arranged to generate power for propulsion, an auxiliary fuel cell stack component, and a processor. The processor, responsive to a crowdsourced average value of an operating parameter of an auxiliary fuel cell stack component of other fuel cell vehicles being different, for a pre-defined power level, than an average value of a same operating parameter of the auxiliary fuel cell stack component by a pre-determined amount, purge the fuel cell stack of nitrogen.
