PCT No. PCT/GR94/00004 Sec. 371 Date Nov. 18, 1994 Sec. 102(e) Date Nov. 18, 1994 PCT Filed Mar. 18, 1994 PCT Pub. No. WO94/22202 PCT Pub. Date Sep. 29, 1994A 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. Every time a sample of the terminal voltage of the battery is taken, COMPARATOR (9) means compare this sample with the one taken in the previous periodic interval and, then, the charging is proceeding when this comparison has a predetermined result (or alternately a combination or combinations of results from comparisons of more parameters), otherwise the charging process terminates.
