| Abstract | As the battery for space, Ni-Cd and Ni-H/sub 2/ is used. Recently, lithium ion battery, which has high energy density high discharge voltage and high efficiency of charge/discharge, is being developed for electric vehicle. We have developed the battery system for GEO to reduce the weight and cost. As the result of the development test and qualification test, we have taken the following data: to meet the life requirement of GEO satellite with protection circuit; GEO: 15 years 3200 cycles; to perform qualification test for GEO satellite; to improve energy to weight at battery system level (from 40 w/g to 110 w/g). Since Mitsubishi Electric Corporation has developed the lithium ion battery system (LIB) which applied large capacity lithium-ion cell (Li-ion cell) for GEO satellite, we describe summary of its system and result of development test. As compared with nickel-hydrogen (Ni-H/sub 2/) or nickel-cadmium (Ni-Cd) cells which has been used for satellite, Li-ion cell has more than two times much energy density and three times much discharge voltage. Therefore Li-ion cell can be realized weight saving, small volume and low cost. Also its cycle life performance is enough to expect long life according to life test at the ground. This LIB consists of battery module (BM) and battery charge control (BBC). BM connects 24 cells, that are nominal capacity 100 AH cells, in series. This LIB and its system are determined to be on GEO satellite. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
