The New PowerShield 8 System
Last Thing to Happen ……
Battery Facts
85% of unplanned outages are due to battery
failure
A battery can fail in days without any sign
One weak battery can deteriorate and damage
other batteries in the string
Battery connections can loosen over time with
heat and cause thermal runaway
The life of a lead acid battery can be shorten by
half for every 10°C over 25°C
Battery Fact
A 10°C increase gives a 50% decrease in life expectancy
The Problems
Plate Separation
Grid Corrosion
Internal and External Short-Circuit
Sulphation of Cell Plates
Excessive Gassing
Dryout
Other Physical Internal Problems
High Resistance Connections
The Causes
High environmental temperatures
Uneven temperatures
Incorrectly setting of float charge voltages
Faults in the UPS charging system
Loose inter-cell links or connections
Electrolyte loss due to dryout
Lack of Maintenance
Ageing
The Cause
Incorrect float voltage significantly affects life expectancy

What PowerShield Measure
Individual Battery Voltage
Individual Battery Impedance
Individual Battery Temperature
String Voltage
String DC Current
Ambient Temperature
Humidity
Ripple Voltage and Ripple Current
What PowerShield Monitor
Individual Battery Voltage – Continuous 4 second sampling
to ensure correct float charge and identify any voltage drop
for each battery
Individual Battery Impedance – detection of faulty battery
before failure and life trend can be used to predict end of
life
Individual Battery Temperature – better knowledge of
temperature gradients in cabinets; detection of thermal
runaway
String Voltage – confirmation of total string voltage and
avoid incorrect float charge affecting the battery life
What PowerShield Monitor
String Current – allows detection of unbalanced strings,
and provides rapid understanding of battery activity
Ambient Temperature at the cabinet/rack – high
temperatures kill batteries. Every 10°C increase gives a 50%
decrease in life expectancy
Humidity – detect of high humidity that can cause
corrosion to the battery terminal
Ripple Voltage – confirmation of UPS operation as
expected in all battery activity
Ripple Current – detect excessive ripple current or
unexpected change over time that damage battery
