Link battery management software
Turning battery data into actionable insight
Link battery management software is a window into the health andperformance of your battery systems. It enables you to make informed
decisions quickly and proactively. Bundled with your PowerShield 8 system,
the Link software application manages the Controller and records all battery
readings in its database for viewing, trending and reporting.
Data is turned into actionable information in the form of alerts anddashboards. Link also sends key information to control room and facility
management systems. Available across sites and to multiple users, Link
comes with no additional licensing or costs.
What’s the juice?
• Instant, clear information for making decisions about your batteries.

Key features:• Reduce the cost of manual monitoring andintervention (and the associated health andsafety risk).
• Live discharge data.
• Permanent connection to multiple sites: forunlimited number of batteries.
• Real time battery status.
• Remote access via LAN.
• Alarm and activity log.
• Graphing and analysis tools.
• Discharge – individual events in detailed
activity summary.
• Trending – impedance change, end-of-life,charge voltage, temperature.

• Confidence that the right people will be alerted to any issues and be able to takeaction.
• Ease of operation and training.

Reporting service
Talk to your PowerShield representative about our monthly Reporting Service which provides expert analysis of your battery
monitoring data.
• Complete awareness of the overall
condition of your batteries.

• Assurance any battery issues will beidentified to enable a timely response.

Controller
The brain of your battery management system
The Controller is an intelligent hardware device that at four second intervals
captures, processes and stores all relevant data collected from batteries andthe operating environment.
With regular monitoring comes the accumulation of data, the ability to reportand spot trends, and make informed decisions. At the heart of this is theController. Dependent on the size of your organisation, PowerShield 8 offers
flexibility and scalability with two Controller options – MX and LX. Similar
in capability, Controller MX has been designed for small to medium size
battery systems of up to 4 strings. Alternatively, Controller LX supports larger
configurations of up to 8* strings of batteries.
The Controller captures, processes and stores data from the Hubs andmSensors. This includes battery voltage (DC and ripple), impedance andtemperature, string voltage and current (DC and ripple), humidity, plus
ambient temperature.
What’s the juice?
• Have confidence that battery data is being gathered and recorded every four
seconds.

• Reduce the internal effort required formonitoring battery performance data.

Key features• Simple installation, minimal cabling and thecapability to monitor UPS batteries that are up
to 8 strings per system.
• A user-friendly web interface withsmartphone/tablet friendly status screens.
• Dry contact inputs can be utilised formonitoring battery breaker status, door status,
electrolyte level sensors or other 3rd partydevices.
• Battery behaviour captured accuratelythrough non-latching alarms, providing highresolution record of battery readings thatcross two level alarm limits. Also captures theextreme values recorded during alarms.
• Integration with infrastructure management
systems enabled with built-in protocols(SNMP, ModbusTCP, HTTP).
• Access options for non-networked sites,
including LCD version of the Controller LX withkeypad access, and simplified data collection
option with USB port.

• Know that battery data will always be available and problems identified quickly.
• Find the option for accessing and understanding the data recorded that suits
your operation.

Supporting components
HubA Hub on each battery string connects the various data points required to provide an accurate picture of your battery bank’s current
and future state.
The Hub reduces the need for excessive cabling. It allows for more batteries to be added to every cable as well as being able to hold
two roles (e.g. ambient temperature and current transducer). This reduces the clutter of a system and streamlines the configuration.
The Hub takes inputs from sensors at the battery rack and connects them through to the Controller. It also connects with externalsensors to measure current and ambient temperature, and has an on-board sensor to gauge humidity, communicating this data to
the Controller for aggregation.

mSensors
mSensors enable you to quickly and accurately record data from every
battery. Located at the battery, mSensors gather individual voltage (DC andripple), impedance (Ohmic value) and temperature for VRLA, VLA and Ni-Cd
batteries.
Advanced circuits in the mSensor drive fast data sampling and powerfulmeasurement algorithms. 750Vdc optical isolation inside the mSensor
keeps the dangerous voltages at the battery and away from the operator,
while still ensuring battery data is passed to the monitoring system atspeed.
Designed for use with batteries in racks or cabinets, mSensors come withpre-terminated harnesses, making them a simple ‘plug and play’ solution.
This makes the hardware easy to install.

Key features:• Ni-Cd, 2V, 4V, 6V, 8V, 12V, 16V solutions.
• Simultaneous voltage sampling across allbatteries.
• Temperature measured at negative terminalas per IEEE guidelines.
• 750Vdc optical isolation.
• Factory terminated harness.
• Cabinet or rack compatible.
• On-board high precision reference for
impedance self-calibration.

Available as separate components
The mSensor communicates via Modbus, meaning it can be easily integrated with existing site management devices.
This allows expansion of your remote monitoring capabilities, without additional infrastructure. Alternatively, through acommunication interface, battery data can be pushed direct to the cloud independent of existing equipment.
