  • Method and apparatus for charging rechargeable batteries
    Patent number: 6489750
    Abstract: A method and apparatus for charging a rechargeable battery with a current from a controllable current source. In order to adjust the rated current of the controllable current source, at least one operating parameter of the rechargeable battery, such as the rechargeable battery voltage which is produced as a consequence of a charging process, is detected. A pulsed control signal with a duty ratio which corresponds to the desired rated current is produced as a function of the operating parameter. The duty ratio of the pulsed control signal is evaluated, and the rated current of the current source is adjusted as a function of the duty ratio of the pulsed control signal.
