PCT No. PCT/AT89/00027 Sec. 371 Date Sep. 10, 1990 Sec. 102(e) Date Sep. 10, 1990 PCT Filed Mar. 10, 1989 PCT Pub. No. WO89/08940 PCT Pub. Date Sep. 21, 1989.Process for charging accumulators and circuit versions for implementing said process. The charging state of a 100% charged accumulator is determined by the detection of an extreme value in the trend of a parameter (S), which is related to the inner voltage or the inner resistance of the accu. The extreme value can be detected by means of electronic analog-digital or computer circuits. These circuits can be produced by discrete or hybrid technology and can be integrated on a monolithic substrate. Besides an improvement in reliability, the process is applicable for charging undetermined accumulators directly out of unstable sources like solar generators, dynamos, weak supplies, or similar. |
