摘要： Improvements in startup time for an electrochemical fuel cell system from freezing and sub-freezing temperatures may be observed by minimizing the coolant volume in the coolant subsystem. In particular, this may be accomplished by having a two pump (50, 55) - dual loop (A, B) cooling subsystem. During startup, one pump (55) directs coolant through a startup coolant loop (A) and after either the fuel cell stack (20) or the coolant temperature reaches a predetermined threshold value, coolant from a main or standard coolant loop (B) is then directed to the fuel cell stack (20). In an embodiment, coolant from the standard loop (B) mixes with coolant in the startup loop (A) after the predetermined threshold temperature is reached.

摘要： The invention concerns a method to cold-start a fuel cell system at subzero temperatures, whereby the fuel cell system comprises a fuel cell stack, upstream of which is connected a heating device to heat a cooling agent to be circulated by a coolant pump. To reduce the demand for stored electrical energy, a cold fuel cell stack is operated at such a capacity that it generates sufficient power to operate the heating device and the coolant pump; the power generated by the fuel cell stack is used to operate the heating device for heating the cooling agent as well as the coolant pump, whereby the coolant pump circulates the cooling agent between the fuel cell stack and the heating device; and the heating device is switched off as soon as the fuel cell stack reaches a preset temperature that is higher than the original temperature.

摘要： A power system employs an outer voltage feedback loop and an inner current feedback loop to control a power converter, such as a DC to AC inverter for transferring electrical power between a power source, for example a photovoltaic array, and a load, for example a power grid. The outer loop accommodates variations in the output of the power source, for example accommodating anomalies in IV characteristics such as IV droop characteristic associated with photovoltaic cells. The outer loop may employ a first control regime or a second control regime, for example, dependent on whether a DC bus voltage or power is smaller than a value corresponding to measurement resolution or expected noise.

摘要： A rotor assembly for use in an electric motor or generator where the mass of the rotor assembly is reduced with respect to conventional rotor assemblies. In addition, the rotor assembly is configured to be scalable to different sized electric motors. Within the rotor assembly, the rotor hub, the shaft, and the permanent magnets can independently or collectively be modified to have a reduced mass. In one aspect, a portion of the rotor hub adjacent to the shaft is configured with passages and spokes. In another aspect, an intermediate hub with lightening holes is provided between the shaft and the rotor hub. In yet another aspect, a large diameter hollow shaft replaces a portion of the rotor hub. In yet another aspect, the permanent magnets are configured to have an arc-shape, which permits the thickness of the magnets to be reduced without reducing the efficiency of the magnets.

摘要： A control system, method and article allows a monitoring module to monitor operation of a main controller in an electric drive, by providing questions and evaluating the accuracy and/or timeliness of responses from the main controller. Upon detection of an excessive number of incorrect or late responses, the monitoring module can shutdown operation, and may provide an alternative communications path, thereby preventing corrupt data from reaching a vehicle network, while providing communications for diagnostic and recovery such as by provision of new software or firmware instructions. The main controller may monitor the operation of the monitoring module, taking appropriate action if a fault is detected. Disabling a supply of power to a traction motor may be based on current operating conditions, such as speed.
