PROBLEM TO BE SOLVED: To provide an improved battery charger system and battery charger method which improves efficiency in a battery charging process.SOLUTION: A switching regulator receives an input voltage and an input current. An output terminal of the switching regulator is coupled to a battery to be charged. The switching regulator provides a current into the battery that is larger than the current into the switching regulator. As the voltage on the battery increases, the current provided by the switching regulator is reduced. The present invention may be implemented using either analog or digital techniques for reducing the current into the battery as the battery voltage increases. |
