Superior battery management
Battery service life is a major contributor to UPS reliability. Since
batteries are electrochemical devices, their performance gradually
decreases over time. Premature wear-out means higher costs in
terms of replacement labour and shorter service cycle. A worn
battery entails a risk of unexpected load loss. In normal UPS oper-
ation, backup power is needed only occasionally and the battery
‘wearing’ rate depends strongly on how the full charge is being
maintained. Excess charging is detrimental under any operating
circumstances.
Significant extension of battery life
Eaton has created ABM
®
technology to extend the life of valve-
regulated lead-acid batteries by applying sophisticated logic to
the charging regime. Using the traditional trickle charge method,
batteries become subject to electrode corrosion and electrolyte
dry-out, especially in standby service use due to continuous float
charging. ABM is essentially an addition of intelligence to the
charging routine by preventing unnecessary charging, thus signifi-
cantly retarding wear-out. ABM provides an additional feature for
monitoring battery condition and advance warning about the end
of battery life upon detection of a weak battery. It also optimises
the recharge time, which is advantageous when there may be
consecutive power outages within a short period. ABM has been
used for over 15 years in our UPSs ranging from 1 to 160 kVA and
is now applied in UPSs up to 1100 kVA.
