Investigation of Pre-conditioning Strategies that Enable State-of-Health Improvement for A Remanufactured Li-Ion Battery in Automotive Circular Economy Applications2018-01-04444/3/2018
Implementing and optimizing the sustainability of vehicles that contain embedded electrochemical energy storage have recently been afforded more attention in research due to legislative requirements and cited benefits from circular economy activities. The State-of-Health (SoH) for a traction battery system that prematurely failed can be restored through circular economy activities such as remanufacturing. To enable these circular economy activities, the ability to introduce a new or graded cell or module into a series string to replace the weakest cell or module in a battery module or pack is vital. However, very little is understood about the optimal strategy that will lead to maximizing the lifetime of the most aged cell or module in the new string and predict the expected lifetime of the repaired or remanufactured battery system. The aim of this research is to assess whether aged lithium-ion cells in series, with some of the aged cells replaced with new cells, have an optimized pre-conditioning strategy to ensure the weakest cell’s life is prolonged. Three modules with six 18650 cells in series have been evaluated to determine the optimal replacement strategy for an energy storage unit albeit cell or module in series for in-use life extension activities. Results highlight that it is possible to significantly reduce the degradation of the weakest cell in a repaired string of series cells. Reduction of circa 4% in aging of the weakest cells is reached with bottom pre-conditioning, while an increase in degradation of the new cell is only 2.5% relative to the worst case scenario. Additionally, the authors show that the energy capacity of the string pre-conditioned at the top reduces the most during cycling of the three strings. Based on these experimental results, an optimal pre-conditioning strategy for circular economy activities for electric vehicle traction battery systems is proposed.

Remanufactured Products: A New Business Model For Light-Vehicle OEMs2012-01-03534/16/2012
This paper will recommend that the Big-3 carve-out a new business unit that focuses upon the delivery of light-vehicles to fleet operators which are classified as “remanufactured”. The remanufacturing process, as applied to this paper, assures that a not-new product has “like-new” condition characteristics of reliability levels, energy efficiencies, operational capabilities, maintainability, safety and others. This new remanufacturing business model is primarily foreseen to: Materially increase the profit margin of the light vehicle fleet market segment Decrease the market share of imported designed-for-manufacturing components employed in the vehicle production process Reduce the manufacturing impact of light-vehicles upon industrial energy consumption and waste generation Mitigate the loss of control of the design of a vehicle to the Federal Government This article will provide an overview of the following nine elements of this new business model: 1 Who is the customer? 2 What is the value proposition for the customer? 3 What are the channels employed to deliver the value proposition to the customer? 4 How are customer relationships established and maintained with the customer? 5 What are the revenue streams? 6 What are the key processes that deliver a value proposition? 7 What key resources are required to be employed in the processes? 8 What are the key sources-of-resources employed in the process? 9 What is the cost structure? It is the author's belief that the time has come for the Big-3 to think out-of-the-box regarding how they do business. The transition will not be easy, but the anticipated rewards of delivering remanufactured products will be one piece of the puzzle that will be employed to reinvigorate the domestic auto industry.

Refurbishment of 767 ASAT Drill-Rivet-Lockbolt Machines2010-01-18449/28/2010
Boeing has relied upon the 767 ASAT (ASAT1) since 1983 to fasten the chords, stiffeners and rib posts to the web of the four 767 wing spars. The machine was originally commissioned with a Terra five axis CNC control. The Terra company went out of business and the controls were replaced with a custom DOS application in 1990. These are now hard to support so Boeing solicited proposals. Electroimpact proposed to retrofit with a Fanuc 31I CNC, and in addition, to replace all associated sensors, cables and feedback systems. This work is now complete on two of the four machines. Both left front and right front are in production with the new CNC control.

Refurbishing Passenger Carriages in the Bulgarian State Railways2001-01-329410/1/2001
The paper presents the problem of refurbishing passenger carriages for the needs of BDZ as a way to increase the speed, reliability, comfort and the quality of the services in the Bulgarian railways. That is an appropriate solution under the conditions of economic crisis in the country. The carriages produced in Bulgaria have turned to be unsuitable for refurbishing so a number of used carriages have been imported from Germany and Austria. Refurbishing has been done at the Plant for Carriages in Drianovo according to the European standards and environmental requirements. The problem examined in the paper is of great importance for the quality of the mass passenger transport in Bulgaria and its improvement as a requirement for Bulgaria's integration to the European Union structures.

Alternator Remanufacturing/Rebuilding Procedures Includes Passenger Car, Heavy Duty, Industrial, Agricultural, and MarineJ2075_200103 (Historical)3/1/2001
These remanufacturing procedures are recommended minimum guidelines (with theunderstanding that being more critical is acceptable) for use by remanufacturers/rebuilders of alternators to promote consistent reliability, durability, and safety of remanufactured alternators. Installation of remanufactured or rebuilt products is often an economical way to repair an application even though the products may not be identical to original equipment parts. Before processing any part, a remanufacturer/rebuilder should determine if the original design and present condition of the core are suitable for remanufacturing/rebuilding so as to provide durable operation of the part as well as acceptable performance when installed on the application. The remanufacturer/rebuilder should also consider the safety aspects of the product and any recommendations of the original manufacturers related to remanufacturing or rebuilding this product. While these procedures are meant to be universal in application, various product types have unique features of dimension and design which may require special remanufacturing/rebuilding processes and tests that are either not covered by or are exceptions to these procedures.

Single-Event Latchup Protection of Integrated CircuitsTBMG-18367/1/1998
Many commercially available advanced-technology CMOS and bipolar integrated circuits are susceptible to single-event latchup (SEL) effects caused by heavy ions or protons from cosmic rays or solar flares, making them unsuitable for satellite applications. Remanufacturing the integrated circuits in an inherently SEL-immune process has been an expensive and technically difficult option, as is the alternate option of incorporating latchup protection and recovery circuitry in the spacecraft system's electronics.

Manufacturing The Tektite Habitat7007532/1/1970
Tektite was manufactured by the General Electric Company in conjunction with the Office of Naval Research, Department of Interior, NASA, and other government, industry and academic organizations. It was manufactured to house four marine scientists for a 60-day period on the ocean floor at a 50 foot depth at an isolated site in the Virgin Islands. The habitat and associated surface equipment provided for life support, environmental control, communications, surface monitoring, safety and comfort of the four aquanauts. The Tektite I experiment was completed safely within minutes of the time scheduled many months previously. The habitat was returned to General Electric in Philadelphia where it was refurbished for the Tektite II mission. This mission is currently in progress in the Virgin Islands and is due to be complete in early November 1970.
