Smart battery charging system, method, and computer program product
View Patent ↗An intelligent battery charger is disclosed which tracks usage of the computer by the user and the charging and usage habits of the user. This tracking includes dates, times, and elapsed usage time, as well as dates, times, and elapsed charging time. Parameters regarding the specific battery being charged are also known by the intelligent battery charger. This information is utilized to develop a usage and charging profile for a particular battery in the device for which it is used. To execute a deep cycle, rather than require that the user wait to plug in a charger until the battery level has reached a certain low level, the charger itself controls the on and off operation of the charging system, based on the profiles.
