Abstract
The operating condition and/or characteristics of a battery is tested by obtaining the dynamic voltage-current characteristic of the battery as a function of the charge condition thereof. A controllably varying charging current is supplied to the battery, and the voltage produced across the battery while that current is supplied is measured. The dynamic voltage-current characteristic is obtained as a function of the measured voltage and supplied current. This voltage-current characteristic is compared to predetermined voltage-current characteristics representing batteries of the type being tested in order to determine the operating condition and/or characteristics of the battery under test.
