Development of the state of charge meter for Li/MnO/sub 2/ cells/batteries

Recently the authors began the development of a state of charge meter (SCM) for Li/MnO/sub 2/ systems. They describe the work that was done to find a correlation between residual capacity of the Li/MnO/sub 2/ cell and a measurable electrical parameter. The preliminary results that were obtained during the SCM development for Li/MnO/sub 2/ cells are outlined. Several methods for a residual capacity estimation were applied and showed positive results for 2/3 A Li/MnO/sub 2/ cells. The maximum accuracy was achieved in the cells that were stored for a long time after usage.<
