  • Physical upgrading of scrap from Ni-Cd batteries. A first step toward an integrated metal-recycling process

    This paper deals with the initial stages of an integrated, metal-recycling process for Ni-Cd batteries (potable, sealed type), that is with the dismantling of spent cells and the physical processing of their resulting scrap. The experiments herein are focused on the performance of a customised shredder and granulometric analysis as to the ability of optimising the waste stream prior to the subsequent recovery operations. The results point to some major separation between value and waste fractions around the 14 mesh (1.40 mm) threshold. The value metals (Ni, Cd, Co) seem to concentrate in the lower (finer) fractions, whereas the upper (coarser) fractions are mostly made up of ferrous and organic materials. Even if a definitive cutoff value cannot be put forward as yet, all results so far indicate that the joint optimisation of the former procedures is likely to provide a simple yet effective means of keeping undesirable components out from actual recovery steps downstream.

  • Design and performance of Tropical Rainfall Measuring Mission (TRMM) Super Ni-Cd batteries

    The Tropical Rainfall Measuring Mission (TRMM) is a joint mission between NASA and the National Space Development Agency (NASDA) of Japan. The observatory is designed to monitor and study tropical rainfall and the associated release of energy that helps to power the global atmospheric circulation shaping both weather and climate around the globe. The spacecraft was launched from Japan on November 27, 1997 via the NASDA H-II launch vehicle. The TRMM power subsystem is a peak power tracking system that can support the maximum TRMM load of 815 watts at the end of its three year life. The power subsystem consists of two 50 Ampere hour Super Ni-Cd batteries, gallium arsenide solar array and the power system electronics. This paper describes the TRMM power subsystem, battery design, cell and battery ground test performance, and in- orbit battery operations and performance.

  • A miniaturized tester for detecting weak individual cells in Ni/Cd batteries

    Reliability of battery powered equipment is only as good as the reliability of the power source itself. One way to ensure the reliability of a nickel/cadmium power source is to periodically test the battery under given load conditions and study the reaction. After loading the battery for a specified period of time, a pass or fail determination can be made by comparing the loaded voltage of the battery under test to the expected voltage of a healthy battery subjected to the same test. Most batteries are made up of individual low voltage cells connected together in series to achieve a higher voltage, and it is often only a small number of individual cells that cause a battery to fail the test. Even so, substandard batteries are replaced in their entirety at a substantial cost. A low cost, miniaturized, constant resistance tester has been developed to determine which individual cells in a battery are weak. This is accomplished by automatically loading the cell under test and comparing the final loaded voltage to a preset value. Individual cells found to be substandard may then be replaced at a cost savings to the owner of the battery. Based on parameters specified by the user, the tester can be configured to test individual cells with different capacities and even small battery packs. Results of prototype field tests are presented.<<ETX>>

  • Sealed bipolar Ni-Cd batteries

    Specific energies greater than 70 Wh-kg/sup -1/ can only be achieved for a 24 V Ni-Cd battery by reducing the weight of the bipolar collecting support. SORAPEC-NITECH has developed a lightweight foam substrate with which it is now possible to obtain bipolar electrodes with a collector thinner than 0.1 mm. These high volumetric energy density structures are well adapted for sealed battery applications. The performances of these batteries were studied as well as the optimization measures necessary to regulate the gas evolution in the cell during end of charge. The characteristic curves obtained with such cells during these tests are given.<<ETX>>

  • Tear-down analysis of old Ni-Cd batteries and reduced maintenance procedures

    Major telecom operators are installing Ni-Cd batteries on a much larger scale than ever before, primarily in remote terminals (RTs). The reason for this is the increasingly large number of RTs that are being deployed in the telecom network. As the operating conditions inside RTs are generally much more severe than in a typical central office (CO) environment, telecom operators have therefore faced unexpected problems with traditional valve regulated lead acid (VRLA) batteries. Some have therefore turned to Ni-Cd batteries to cut operating cost and to improve reliability of service. The goal of this paper is to explain how to substantially reduce Ni-Cd battery maintenance and operating costs, and at the same time improve battery life, safety and reliability without the addition of extensive and complex monitoring equipment.

  • A neural network model for Ni-Cd batteries

    Ni-Cd batteries are nonlinear electrochemical devices with different characteristics at different charge currents. This paper proposes a neural network based method for simulation and modeling of Ni-Cd batteries that considers the impact of charge current. Simulations and measurements are performed for the RBF neural network and advantages and limitations of the model are presented. Inputs of the neural network are battery current ( I<sub>bat</sub> ), no load voltage and time (t) while battery voltage ( V<sub>bat</sub> ) is selected as the output. An experimental setup is used to validate the accuracy of the model at different charge rates. Computed and measured results show good agreements for a 7AH, size F, Ni-Cd battery, manufactured by SANYO. Theoretical and experimental results are compared and analyzed.

  • Temperature Controlled Fast-Charge Ni-Cd Batteries

    Sealed Ni-Cd batteries have been widely used because of their excellent performance. And many fast charge system have been investigated and applied. The most popular fast-charge system is a voltage-controlled type. However the circuit is very complicated and costly. We have developed a new temperature controlled fast-charge system which are comprized of a new battery and a simple external circuit. The new batteries are designed to consume oxygen gas as early as possible and to raise its temperature as quickly as possible in the fully charged state.

  • GA-trained GRNN for Intelligent Ultra Fast Charger for Ni-Cd Batteries

    This paper presents an intelligent genetic algorithm (GA) technique for training of a neural network controller to achieve a compact network and to decrease battery charging time. An ultra fast charging device for Nickel- Cadmium (Ni-Cd) batteries is designed through the generalized regression neural network (GRNN) and implemented with the MATLAB/SIMULINK for testing and operating on real system. The input-output data for training neural networks were collected from GA. The suitable data were selected to establish GRNN comprising only 13 processing elements. Each node of RBFs is an extendable support function that overcomes the drawback in the existing compact support radial basis functions (CSRBF). Experiments with real time implementation clearly show that the proposed technique not only requires less neural processing units but also yields less MSE than RBF technique.

Experimental results also confirmed by computer simulation and show control potentialities.
