A method of measuring impedance of a fuel cell stack in a vehicle during driving of the vehicle includes: determining whether an impedance measurement of the fuel cell stack is requested during driving of the vehicle driven by power of the fuel cell stack; turning off a first relay connected between the fuel cell stack and a battery charged by the fuel cell stack when the impedance measurement of the fuel cell stack is requested; connecting a stack load to the fuel cell stack via a second relay and supplying air to the fuel cell stack; and measuring the impedance of the fuel cell stack.

A fuel control system obtains a measured amount of fuel consumed by an engine and one or more corresponding operating parameters of the engine and determines a fuel consumption modeled amount based at least in part on a fuel consumption model of the engine and the one or more operating parameters. The fuel consumption model associates different amounts of fuel that, when supplied to the engine, generate corresponding designated outputs of the engine. The system also determines one or more differentials between the measured amount of fuel and the modeled amount and, responsive to the one or more of the differentials exceeding a threshold value, the system identifies one or more components of the powered system that contribute or cause the one or more differentials and/or changes an amount of fuel supplied to the engine according to the fuel consumption model to obtain a desired output of the engine.

A regenerative braking control system for a motor-driven vehicle is configured to provide a continuous assistant braking force by continuous reverse torque of an electric motor by enabling surplus electrical energy produced by an electric motor to be easily converted into thermal energy in generative braking, using both of a brake resistor and a heater to convert electrical energy into thermal energy, and being able to obtain an interior heating effect by using thermal energy converted by the brake resistor and the heater as heat source for interior heating without discharging the thermal energy to the outside.

An air compressor apparatus for a vehicle configured for appropriately maintaining an internal temperature and a discharge temperature thereof even in a cold environment, and a method for controlling a temperature of the same, includes a compressor body driven by a first motor; a support bracket supporting the compressor body and configured to be coupled to the vehicle; and a heat exchanger provided on one side of the support bracket, and configured for raising a temperature of external air to generate heated air and provide the heated air to the compressor body.

A fuel cell vehicle includes a cabin arranged at a vehicle front portion and provided with a seat therein where an occupant is seated, a fuel cell mounted below the cabin, and an accommodation space formed below the cabin and accommodating the fuel cell. An upper side of the accommodation space is covered with a ceiling surface formed by a bottom portion of the cabin, and a rear side of the accommodation space is opened. The ceiling surface is provided with a detector configured to detect a hydrogen concentration in the accommodation space.

An electrically driven motor vehicle may include a first cooling circuit, a first component, a first heat exchanger, at least one pump configured to convey a coolant, a second cooling circuit, and a second component. The first component may be arranged in the first cooling circuit and may have a temperature which is to be controlled. The second component may be arranged in the second cooling circuit and may have a temperature which is to be controlled. The first cooling circuit and the second cooling circuit may be fluidically separated from one another and may be coupled to one another to transfer heat via a second heat exchanger. One of (i) the first component and (ii) the second component may be configured as at least one of an electrical energy storage and a fuel cell module, and the other may be configured as a secondary braking system.
