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.

This paper presents a two-dimensional movement and the one-dimensional rotating 3 DOF robot that can be used to pick up, delivery and place riveting column, thin axis (referred to as riveting column) and other parts, forming the assembly systems of riveting of sheet metal. In addition to the robot, the system also has moving table, clamp, a number of riveting column station and spin riveter etc. Moving table is equipped with the clamp, it can move in the X and Y directions, respectively. The clamp that fixed the sheet metal work-piece can move in Z-direction, which make it easy for assembling the riveting axis into the riveting holes on the work-piece. Robot can move along the Y axis and swing around the Z axis, make the nozzle that is in the end of manipulator move between riveting column stations and spin riveter, which pick up and place the riveting column. A number of riveting column station is used for store riveting column and sorting them. Spin riveter rotates while moving along the Z axis at the same time, by pressure and rotational force it completes the column riveting on sheet metal parts.

One of the most common problems of autonomous mobile robots is object avoidance in a dynamically changing environment. The effectiveness of algorithms responsible for trajectory planing is largely dependent on the correct sensory input. It is necessary to equip a mobile robot with the proper sensors to allow a correct functioning in unknown terrain. With the high degree of complexity standard point distance sensors are insufficient for high speed movement. The recent development of compact laser range finders allowed the minimization of robot dimensions. Hokuyo UTM-30LX is an example of such a sensor. For a precise understanding of the measurements, a characterization of a sensor is needed. This paper is summarizes the parameters of Hokuyo UTM-30LX laser range finder, in particular: drift effect, influence of target distance, surface brightness, color and material, and the sensor orientation. The parameters measured prove that the Hokuyo UTM-30LX can be used in a mobile robot system for complex object detection and avoidance.

RCT Systems led a team that included Creative Energy Solutions, and NDI Engineering in the development of an Advanced Energy Storage Module (ESM) for the Office of Naval Research (ONR) under a Broad Agency Announcement (BAA) contract for a DDG 51 Fuel Efficiency Demonstrator. The project demonstrated a modular 600kW ESM in December 2010. These modules could be combined into a 3 MW system to allow DDG 51 single generator operations, providing full ship backup power for up to 10 minutes with significant fuel savings. These savings are dependent on the ship operating profile. The BAA assumed 4,000 hours per year per ship of single generator operations. Based on that estimate, the system could facilitate savings of approximately 8000 BBL of Fuel/ship/year, or up to approximately $1.3M/ship/year in direct fuel savings at Jan 2012 DLA Fuel Rates of $160/bbl. This equates to approximately 30direct savings in the ships electric plant fuel usage during peace time cruise and an 8savings in overall ships fuel usage based on Navy Incentivized Energy Conservation (I-ENCON) reports. DoD has mandated the use of Fully Burdened Fuel Cost (FBFC) in all future acquisition decisions. FBFC savings could be as high as $3-5M/ship/year in FY-12 Dollars. We estimate that hardware costs alone could be recouped in approximately 2 years based on FBFC savings. Navy testing at NSWCCD SSES DDG-51 Land Based Engineering Site (LBES) is ongoing, and it is planned to install the ESM in a DDG-51 Class ship in summer/fall of 2012 for an at sea demonstration. The Navy is currently determining the total energy required to be available to satisfactorily de-risk single generator operations on DDG-51 Class ships. While designed for DDG 51, the modular system is potentially adaptable to all Navy and commercial ships, and supports the Next Generation Integrated Power System (NGIPS) Architecture.

This analysis evaluates several operational benefits of electricity storage, including load-leveling, spinning contingency reserves, and regulation reserves. Storage devices were simulated in a utility system in the western United States, and the operational costs of generation was compared to the same system without the added storage. This operational value of storage was estimated for devices of various sizes, providing different services, and with several sensitivities to fuel price and other factors. Overall, the results followed previous analyses that demonstrate relatively low value for load-leveling but greater value for provision of reserve services. The value was estimated by taking the difference in operational costs between cases with and without energy storage and represents the operational cost savings from deploying storage by a traditional vertically integrated utility. The analysis also estimated the potential revenues derived from a merchant storage plant in a restructured market, based on marginal system prices. Due to suppression of on-/off-peak price differentials and incomplete capture of system benefits (such as the cost of power plant starts), the revenue obtained by storage in a market setting appears to be substantially less than the net benefit provided to the system. This demonstrates some of the additional challenges for storage deployed in restructured energy markets.

Concentrating solar power (CSP) deployed with thermal energy storage (TES) provides a dispatchable source of renewable energy. The value of CSP with TES, as with other potential generation resources, needs to be established using traditional utility planning tools. Production cost models, which simulate the operation of grid, are often used to estimate the operational value of different generation mixes. CSP with TES has historically had limited analysis in commercial production simulations. This document describes the implementation of CSP with TES in a commercial production cost model. It also describes the simulation of grid operations with CSP in a test system consisting of two balancing areas located primarily in Colorado.

The overall project goal is to reduce the cost of home and neighborhood photovoltaic storage systems by reducing the single largest cost component the energy storage cells. Solar power is accepted as an environmentally advantaged renewable power source. Its deployment in small communities and integrated into the grid, requires a safe, reliable and low cost energy storage system. The incumbent technology of lead acid cells is large, toxic to produce and dispose of, and offer limited life even with significant maintenance. The ideal PV storage battery would have the safety and low cost of lead acid but the performance of lithium ion chemistry. Present lithium ion batteries have the desired performance but cost and safety remain the two key implementation barriers.

The objective of the Electrochemical Energy Storage program is to develop enabling materials systems for future electrochemical energy storage devices. The program focuses on developing nanostructured electrodes and improved solid state electrolytes for high power & energy density devices and to explore new 3D nanostructured architectures to enable optimal performance. The goal is to supply performance improvement (i.e. increased power and energy density, longer shelf and use life, and higher charge/discharge rates) as well as provide new capabilities such as flexibility or the ability to incorporate energy storage directly into electronic devices, structures, or fabrics. Application focus for improved electrochemical energy storage materials is small autonomously powered remotely piloted aircraft (RPAs), airfield support, deployed airbase power, and portable soldier power. Near term goal is to increase energy density to allow 4-5X mission duration. Long term goal is to provide an autonomous power system by coupling improved energy storage with energy harvesting to permit 24/7 operation.
