摘要： Methods and systems are disclosed for charge current adjustment to enhance battery cycle life thereby allowing batteries to be charged quickly without accelerating the aging process of the battery. As the charge capacity of the battery degrades over time, the charge current for the battery charging cycles is also reduced so that the effective charge rate for the battery is adjusted to account for the reduction in charge capacity. In this way, battery capacity life is enhanced by avoiding an accelerated charge rate as the battery capacity drops over the operational life of the battery. The methods and systems disclosed are useful for battery-powered information handling systems, as well as other devices where fast charging and long cycle life is desirable, such as cell phones, personal digital assistants (PDAs), electric vehicles and/or any other battery powered devices.

摘要： For charging a rechargeable hybrid battery pack, a first cell stack coupled in parallel with a second cell stack of the hybrid battery pack are pre-charged in parallel. The cell stack to first complete the pre-charge phase, is selected to receive a normal charge with a constant current while the non-selected one of the cell stack continues to receive the pre-charge. The first cell stack and the second cell stack receive the normal charge in the selected sequence. Upon completion of the normal charge for each cell of the hybrid battery pack, the first cell stack and the second cell stack are trickle-charged in parallel to complete the charging.
