- APPARATUS AND METHOD FOR DETERMINING THE CAPACITY OF A NICKEL-CADMIUM BATTERY

摘要

The present invention provides a measuring method that can save time for measuring the capacity of nickel cadmium (NiCd) (22). Under test, while continuously sensing the battery terminal voltage, a fully charged NiCd battery 22 is applied a current supply lamp 42 with a positive slope and then a current supply lamp 46 with a negative slope. Plot the voltage and the maximum slope of the measured terminal voltage determines I _gas . Under test, the value of I _gas is compared with the temperature calibration curve to determine the capacity of the battery 22.
