  • Battery charging system, stepping and interactively self-adjusting to the normal voltage of the battery
    Patent number: 5691623
    Abstract: A charging system (1) for a variety of batteries (nominal voltage, capacity, chemical components), stepping, and self-adjusting to the top-of-charge voltage of the battery (12a) by interacting with the terminal voltage of this battery in each one of a series of periodic intervals (steps). CONTROL (2) means are provided for enabling signals (4) in predetermined subintervals in each periodic interval, to control the charging process. The charging voltage parameter in the running periodic interval is set by REFERENCE VOLTAGE (10) means, based on the sample of the terminal voltage of the battery taken by READING (5) means in the beginning of the running periodic interval and slightly amplified by a predetermined factor (25%). Thereafter VOLTAGE REGULATOR(15) means regulate the voltage of the charging current according to, as this set, charging voltage parameter.
