4 The PowerShield 8 Battery Monitoring System
The PowerShield 8 battery monitoring system is a permanent battery monitoring system that can monitor one or more
strings of blocks. Parameters measured include:
• DC & AC voltage of each block
• Ohmic value of each block
• Temperature of each block
• DC string voltage
• DC & AC string current
• Ambient temperature
• Ambient humidity
The diagram on the following page shows an overview of the system which consists of the following hardware:
• PowerShield Controller
• PowerShield Hubs
• PowerShield mSensors
• Current Transducers
• Ambient Temperature sensors
• Hub-to-BBus adaptors (where applicable)
The PowerShield Hub is used to connect external sensors for measuring string current and ambient temperature and has
an on board ambient humidity sensor. The PowerShield mSensor is used to monitor each block. The PowerShield
Controller periodically interrogates each Hub and mSensor and processes the data, logging the information into memory
at predefined intervals.
The distributed system architecture using local Hubs and mSensors installed at the battery bank, connected to the
PowerShield Controller using a single CAT5 cable, allows one PowerShield Controller to monitor multiple remote strings.
A single system can also monitor different voltage blocks and strings using appropriate mSensors.
PowerShield provides Link software for automated multi-site battery management.
