ABSTRACT:
A method of checking a storage battery with series-connected cells comprises the steps of:
Passing a charging current pulse through the battery,
Measuring an elementary transient voltage at the terminals of each storage cell; and
Comparing elementary transient voltages with the average transient voltage of the said storage cells (total transient voltage divided by the number of storage cells).
The battery is rejected if the absolute value of the difference between the said average transient voltage and one of the elementary transient voltages, when the difference maintains a constant sign, becomes higher than a predetermined threshold and, when the difference changes signs, if the sum of the maximum absolute values of the differences in constant sign becomes higher than a predetermined threshold. Application: checking lead-acid storage batteries when they come off the production line.
