Remote battery discharge testing method and apparatus

摘要

Disclosed is an apparatus for providing remote testing and monitoring of equipment backup batteries at the location of the batteries. The testing can be accomplished upon command from a remote terminal or remote agent as well as in accordance with predetermined parameters programmed into a processor at the remote site. The test is accomplished using the normal site load while reducing the amplitude of the DC (direct current) output voltage, obtained from an AC (alternating current) rectifier used at the site, from a battery charging "float" level amplitude during the duration of the test. The discharge curve obtained during the test is compared with previous and/or standardized curves to ascertain the condition of the battery tested and/or the likelihood of near future failure of the battery tested.
