  • 52443.人机接口控制器的可用性任务规划

    [电气机械和器材制造业,汽车制造业] [2013-12-28]

    Unmanned ground and air vehicles (UGVs and UAVs) embody a critical capability of future U.S. Army systems and will be used for force projection and as force multipliers. They are expected to operate in a semiautonomous fashion, in which an operator will lay out a mission plan for the vehicle to execute with little or no operator interaction; the operator s function will be to monitor the progress of the unmanned systems. If the situational demands exceed the capabilities of the vehicle, the operator will need to intervene to complete the mission by either changing the mission plan or by assuming direct control of the vehicle by teleoperation until the vehicle can resume semiautonomous operation.

  • 52445.模块化储能系统的新能源汽车

    [电气机械和器材制造业,电力、热力、燃气及水生产和供应业,汽车制造业] [2013-12-24]

    An electrical vehicle environment was established to promote research and technology development in the area of high power energy management. The project incorporates a topology that permits parallel development of an alternative energy delivery system and an energy storage system. The objective of the project is to develop technologies, specifically power electronics, energy storage electronics and controls that provide efficient and effective energy management between electrically powered devices in alternative energy vehicles--plug-in electric vehicles, hybrid vehicles, range extended vehicles, and hydrogen-based fuel cell vehicles. In order to meet the project objectives, the Vehicle Energy Management System (VEMS) was defined and subsystem requirements were obtained. Afterwards, power electronics, energy storage electronics and controls were designed. Finally, these subsystems were built, tested individually, and integrated into an electric vehicle system to evaluate and optimize the subsystems performance.

  • 52446.Plug-ln汽车电池的第二次生命:电网储能价值对电池租赁付款的影响

    [电气机械和器材制造业,汽车制造业] [2013-12-24]

    This research analyzes the potential reduction in battery lease payments for plug-in electric vehicles (PEVs) in California that incorporate the value from postvehicle, stationary provision of grid services. PEV batteries repurposed into distributed electrical storage appliances (DESAs) might provide valuable services to electricity customers, utilities, and regional grid operators alike, with improved grid operation, deferred costly upgrades, and support for the penetration and profitability of intermittent renewable energy. This research advances methods for analyzing combined vehicular and postvehicular value and uses new and increasingly sophisticated inputs, including specific PEV characterizations and value for 19 grid applications. The results showed positive but sometimes modest potential benefits. Bounding scenarios all showed reductions in battery lease payments. For the Chevy Volt-based example, which exhibited a 22reduction in the base case, the bounding scenarios ranged from 1to 32. Monte Carlo analysis indicated that the point estimates that were developed might need downward adjustment to account for uncertainty, a situation that would possibly negate second-life benefit. The analysis indicated that if valuable regulation revenues were hotly contested and provided limited impetus to DESA commercialization, value from multiple applications would be necessary to support profitability. This possibility makes the artful combination of services a critical uncertainty. One previously identified combination of multiapplications related to servicing local air-conditioning loads was examined as the base case and was found to be attractive. Another important uncertainty is the cost of power-conditioning requirements, which must also be optimized or reduced with specific combined-load profiles, for example, through coupling DESAs with local photovoltaics.

  • 52447.国家再生能源实验室能源存储项目:2012年度年报

    [汽车制造业,电气机械和器材制造业,电力、热力、燃气及水生产和供应业] [2013-12-24]

    This report describes the activities of the Energy Storage group over FY2012. The National Renewable Energy Laboratory (NREL) supports energy storage R&D under the Vehicle Technologies Program at the U.S. Department of Energy (DOE). The DOE Energy Storage Programs charter is to develop battery technologies that will enable large market penetration of electric drive vehicles. These vehicles could have a significant impact on the nation's goal of reducing dependence on imported oil and gaseous pollutant emissions. DOE has established several program activities to address and overcome the barriers limiting the penetration of electric drive battery technologies: cost, performance, safety, and life. These programs are: (1) Advanced Battery Development (through the United States Advanced Battery Consortium (USABC)); (2) Battery Testing, Analysis and Design; (3) Applied Battery Research (ABR), and (4) Focused Fundamental Research, or Batteries for Advanced Transportation Technologies (BATT).

  • 52449.高级量程安全系统的高能源汽车

    [汽车制造业] [2013-12-23]

    The advanced range safety system project is a collaboration between the National Aeronautics and Space Administration and the United States Air Force to develop systems that would reduce costs and schedule for safety approval for new classes of unmanned high-energy vehicles. The mission-planning feature for this system would yield flight profiles that satisfy the mission requirements for the user while providing an increased quality of risk assessment, enhancing public safety. By improving the speed and accuracy of predicting risks to the public, mission planners would be able to expand flight envelopes significantly. Once in place, this system is expected to offer the flexibility of handling real-time risk management for the high-energy capabilities of hypersonic vehicles including autonomous return-from-orbit vehicles and extended flight profiles over land. Users of this system would include mission planners of Space Launch Initiative vehicles, space planes, and other high-energy vehicles. The real-time features of the system could make extended flight of a malfunctioning vehicle possible, in lieu of an immediate terminate decision. With this improved capability, the user would have more time for anomaly resolution and potential recovery of a malfunctioning vehicle.

    [电力、热力、燃气及水生产和供应业,汽车制造业] [2013-12-23]

    The study analyzes the potential market penetration in Arizona of various types of alternate energy vehicles. The market penetration is analyzed in terms of changes in the price of fuel, tax incentives, costs of conversion and consumer attitudes. Short term market penetration, in the absence of legal intervention, is expected to amount to a very small fraction of the total operating fleet of motor vehicles.
