In the Battery Room
All parameters sampled continuously & automatically Rapid identification of catastrophic failures
Automatic data logging Allows historic & predictive trending over battery lifetime
Automatic data logging of battery discharge Live assessment of performance Capacity analysis
UPS self-test & intermittent charging compatibility Make best use of UPS functionality
All events and alarms time & date stamped

At the Battery
750VDC optical isolation at battery Increased safety of personnel & facility Install flexibility & efficiency – consolidate different block & string voltages [UPS, 48V, genset, emergency lighting] Factory terminated cable sets with no fusing required
Intelligence at the battery Ripple & noise rejection Self-protection Bi-colour LED for fast identification
No more manual battery testing.

Raising the Alarm
Alarms for block voltage, impedance & temperature [thermal runaway]; string voltage & current; ambient temperature
All alarm settings user-editable, but with initial defaults offeredSelf-learnt automatic baseline for impedanceAll alarm settings are battery & application specificDetailed, specific alarm information – to individual block levelSystem intelligence applies appropriate limit set for battery state –
Float/Charge/Discharge/IdleNotification of change of string stateAlarms for internal system diagnostics

Notes: What We Measure & Why
Individual block voltage – ensure correct charge and performance under load
Individual block impedance – impedance change gives a solid life trend and end of life assessment.
Ambient temperature at the cabinet/rack – high temperatures kill batteries. A 10°C increase gives a 50% decrease in life expectancy
String current – allows detection of unbalanced strings, and provides rapid understanding of battery activity
String voltage – confirmation of UPS operation & compliance with battery specification
Individual block temperature [optional] – better knowledge of temperature gradients in cabinets; pre-empt thermal runaway
