Fundamental characteristics of stationary lithium-ion secondary cells and a cell-voltage-management system
2004
This paper describes the results of several performance tests evaluating lithium-ion cells developed for stationary use, such as stand-by sources in power systems. The effect of a cell-voltage-management system developed for batteries of cells is also shown. The tested cells were suitable for being charged by using the constant-current and constant-voltage (CCCV) method and could be charged efficiently over a wide range of temperatures. They also showed good discharge performances that were scarcely influenced by the discharge current and temperature. The cell-voltage-management system was revealed to be useful for the suppression of deviation of cell voltage and capacity loss.
