6.8 Float current per string.

7 System Hardware and Software Requirements

7.1 All components of system are to be 19” rack mountable.

7.2 LEDs indicating alarms, communications, and processor status.

7.3 Two RS‑232 serial ports: One port shall be configurable for either a local PC to be connected at all times or for temporary viewing with a laptop computer. The second port shall be configurable for use on a network using TCP/IP. Setup and viewing of data is to be performed from either one of these ports.

7.4 EEPROM: Nonvolatile memory for storage of data. Enough memory storage for one complete year of data.

7.5 Wiring harnesses with supplied connectors to be terminated in the field during installation.

7.6 Individual fused leads to each battery cell/jar for resistance test load cables, and resistor terminated leads for voltage sense.

7.7 Ring connector terminals at each connection.

7.8 Two voltage-free, form C, alarm contacts for annunciating a common alarm to the alarm reporting system. Each contact can be programmed for either a critical or maintenance event.

7.9 Windows 95/98/NT/2000 compatible software for data analysis, display, archiving, and trending.

8 System Performance

8.1 The BMDMS shall monitor, display, and record the battery bank voltage, battery discharge current, individual cell voltages, configured temperature, individual cell resistance, intercell connection resistance, and intertier resistances. All these parameters shall be continuously monitored in real time during normal operation and during all battery discharges, except for resistance test, which is a user programmable event.

8.2 The BMDMS shall transfer all battery parameters specified in paragraph 8.1 at the remote central computer (RCC), at user defined intervals.

8.3 The system shall automatically display, record, and provide a print-out of all alarm conditions, as and when they occur, at the RCC. This reporting shall include the following parameters.

8.3.1 Individual cell voltage high and low alarm.

8.3.2 Individual internal resistance high alarm.

8.3.3 Individual internal resistance warning as a percentage of alarm threshold.

8.3.4 Intertier resistance high alarm.

8.3.5 Overall voltage high and low alarm.

8.3.6 Temperature high and low.

8.3.7 Individual cell voltage low alarm during discharge.

8.4 Each alarm record shall include defined limits, alarming parameter, show the time and date of the event, and the peak value reached during the violation.

8.5 Each parameter alarm shall be configurable for a latching or non-latching alarm contact function.

8.6 As user defined, the system shall automatically page or fax a report to responsible personnel when any alarm thresholds are violated.

8.7 The system shall provide and maintain a complete, real-time discharge event log and a dynamic on-line display of battery voltage, individual cell voltages, battery string current, and ambient temperature whenever the battery is in a discharge mode. In addition to the numerical display, the system shall provide a graphical display of the battery voltage and cell voltages versus time that allows playback of the discharge event.

8.7.1 Store historical record of the internal cell resistance of each cell.

8.7.2 Store historical record of each intercell connector resistance.

8.7.3 Display the actual real time numbers (or stored snapshots) of all battery parameters at the remote central computer. Additionally, the display shall provide individual graphical representation of all battery parameters in relation to alarm thresholds.

9.1 The BMDMS shall require a password to allow any programming or calibration changes either via remote connection or local connection.

10 Software

10.1 The software shall operate on the Windows 95/98 operating systems. The software shall be responsible for maintaining a database of all information gathered from the monitors for future analysis and reporting. The software shall be configurable for either a central, local or service computer application. The central configuration shall be responsible for permanently removing any data that may reside in the monitor E² memory. The local configuration will not permanently remove data from E² memory and will allow it to remain for the central computer. The service configuration will allow service technicians to call for real time analysis from any accessible phone line . The software shall be able to autopoll multiple monitoring systems on a programmed schedule.
