| description | An uninterruptible power supply system includes an input configured to couple to a power source, an output configured to couple to a system load, a battery, power circuitry coupled to the input, the output, and the battery, and configured to transfer power from the input to the output and to transfer power from the battery to the output, a test load, a test switch coupled to the battery and the test load and configured to selectively couple the battery to the test load, a voltage monitor coupled to the battery and configured to provide an indication of a voltage provided by the battery, and a processor coupled to the test switch and the voltage monitor and configured to effect a first partial-discharge test on the battery by actuating the test switch to couple the battery to the test load to partially discharge the battery, and by using information from the voltage monitor regarding the voltage provided by the battery at different times during the test before a complete discharge of the battery to determine a capacity of the battery. |
