WebIn this paper, the direct wave pulse method is used to measure the internal resistance of the cell. The effects of depth-of-discharge (DOD) (between 10-90 % ), ambient temperature (-25 to 50 degrees Celsius), and aging (up to 800 cycles) on the internal resistance of a 20Ah lithium-ion polymer battery cell are investigated. WebWe present a novel approach for a battery management system in which adaptive thermal control is employed to balance the capacities of individual groups of cells within a lithium-ion battery pack. Maintaining capacity balance within the battery pack in this manner can significantly extend its cycle life.
