5 1 Glossary Cell the basic electrochemical unit that can receive, store, and deliver electrical energy. Block one or more cells in a container also known as a battery. The terms block and jar are interchangeable. For this manual the term has been standardised as block to avoid using the somewhat unwieldy convention of "block/jar" throughout. String two or more blocks connected in series. Battery Bank PowerShield Controller PowerShield msensor PowerShield Hub BBus complete system of parallel connected strings. data logger that periodically communicates with PowerShield Hubs and PowerShield msensors to obtain system measurements. remote sensor that is connected to the blocks. It periodically measures the block voltage, ohmic value and temperature. remote sensor that can be used to measure string current and ambient temperature of the battery bank. msensors can be connected to it so that they share the same communication cable from the PowerShield Controller. daisy chain communication bus used between the PowerShield Controller and PowerShield Hubs or PowerShield msensors. Part No A Page 5 of 77

6 2 The PowerShield 8 Battery Monitoring System The PowerShield 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 & 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 measure string current, ambient temperature and ambient humidity. 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.

8 3 The PowerShield Controller This manual provides information on how to configure and setup the PowerShield Controller component of the PowerShield 8 system. Configuration of the PowerShield Controller should take place after the system has been installed please refer to the PowerShield 8 Installation Manual for more information. 3.1 String States The PowerShield Controller reads each string that has been set up within the system and determines the string state that each particular string is in. It does this by analysing the current and average block voltages within each string. The string state reading for each string is important for two reasons: When in the charging or discharging state the Controller creates a detailed measurement log (see Section 7.13 Logs Measurement). Certain measurements, such as Block Voltage, will use different limits according to the string state (see Section 7.7 Limits). Refer to the diagram PowerShield System and Battery State Change Voltage and Current on the following page for an explanation of battery states and how the PowerShield system changes operation to suit. Part No A Page 8 of 77

9 Figure 2 PowerShield System and Battery State Change Voltage and Current Label Description 1 Discharge String current must drop below the Discharge Threshold for the system to recognise a Discharge state. 2 Charge String current must rise above the Charge Threshold for the system to recognise a Charge state. 3 Float String current must drop below the Charge Threshold for the system to recognise a state change to Float. 4 Idle Average block voltage must drop below the Float Threshold for the system to recognise a state change to Idle. Part No A Page 9 of 77

10 3.2 Alarms Alarms are used by the PowerShield Controller to alert the user of any potential anomalies or configuration errors within the system. Alarm types include: System Alarms these alarms alert the user to any hardware or system configuration errors that may arise. Block/String Alarms these alarms alert the user to potential issues pertaining to the battery installation for both strings and monoblocks. Warnings and Critical Alerts Alarms will be raised whenever measurements exceed predetermined limits. Part No A Page 10 of 77

11 3.3 Ohmic Measurements The health of a block may be determined by measuring its impedance value with respect to a predetermined reference value. This value may be set either manually by the user or calculated automatically by the PowerShield Controller. The reference value is referred to here as the Ohmic Baseline. The initial baseline reading is known as the temporary baseline (see Figure 3). This baseline is used only temporarily and is a transitional baseline measurement. After a period of time determined by the ohmic schedule the baseline measurement is taken again. The interval between the temporary and the permanent baseline readings spans a period of six months by default this period, however, may be customised by the user. The average value of the last seven consecutive days of this schedule is then used to determine the permanent baseline. Clicking Force Ohmic Baseline Measurements will initiate the baseline measurement process for all strings that have not yet had a baseline measurement taken. Figure 3 Baseline Status Baseline Value Baseline Date No baseline set - - Temporary baseline set Temporary Value Date between when the temporary baseline is set and the scheduled permanent baseline set date Permanent value set Permanent Value Date when the permanent baseline value was set User value set Value Date when the baseline was set by the user Please note that with an intermittent charging setup the baseline will be created based on 28 consecutive measurements.
