A battery is charged by repeatedly alternating between test and charge cycles. During the test cycle, the dynamic voltage-current characteristic of the battery is obtained as a function of the charge condition of the battery. During the charge cycle, a gradually varying voltage is supplied to the battery, substantially without controlling the current supplied thereto, for a predetermined time. The rate at which this supplied voltage varies is related to the dynamic voltage-current characteristic obtained during the test cycle. Alternating between test and charge cycles continues until the dynamic voltage-current characteristic last obtained is substantially identical to the preceding dynamic voltage-current characteristic, whereupon the charging of the battery is terminated. |
