Computer based evaluation of battery capacity tests

The fully charged state and the ageing process of stationary batteries cannot be followed easily. The most effective method is the capacity test, which gives an exact result about the condition of battery cells. However, these results can depend on people who do the measuring. The evaluation of several different discharge processes are very hard because of the large amount of data. This paper introduces a computer-aided battery capacity test evaluation procedure which gives well ordered data sheets, shows the selected values in diagrams, calculates the partial and final results in the same way, so the results of different measuring series will be comparable. The program is able to compare the results of annual capacity tests and gives a good view about the expectable future behavior trend of the examined batteries.<
