IBEX User Manual Part 6
8. PC Monitor program for IBEX
Exmons Pro 2005 is a comprehensive diagnosis program to ensure the integrity of your stationary batteries and any power backup systems. Measured data are easily recognized so as for users to effectively manage the stationary batteries.
* Benefits of Exmons Pro 2005 are as follows : EXMONS Pro 2005 program manual is described in electronic files contained in the program CD.
1. By constructing database of the IBEX measuring data, it can be stored and managed as a site-specific tree structure in the PC.
2. As it provides handy information such as a stationary battery’s deterioration displayed in a range of graphs as well as various screen menus, it allows users to analyze and determine the status of stationary battery in a highly user-friendly environment.
3. As it has a bank-specific report printout function, it frees users from the manual documentation and allows them to utilize the analysis outcomes.
4. After entering the stationary battery data and parameter setup value in the Exmons Pro 2005 program, users can transfer data to the IBEX
5. By saving the measuring data in excel file, it facilitates documentations of the data.
8.1 USB Driver installation
1) After connecting a cable to the IBEX USB PORT and the USB terminal of the computer, the computer monitor will display a message window indicating a new hardware has been found as shown in Figure_63) .
2) As shown in Figure_64), when a new hardware search wizard window pops up, press the next (N) button.
3) As shown in Figure_65), select the appropriate driver search (recommended) to search the IBEX driver, then press the next (N) button.
4) As shown in Figure_66), after selecting the folder or CD that has the IBEX USB driver, select the FTDBUS.INF file then press the open.
5) As shown in Figure_67), when a window confirming the driver installation, press the finish button.
6) When the search wizard is completed, the new hardware search wizard window will appear once again as shown in Figure_68). Then press the next (N) button as the above (2)
7) As shown in Figure_69), select the FTDIPORT.INF file in the driver folder then press the open.
As shown in Figure_70), when a driver installation notification window appears, press the finish button to complete the IBEX USB driver installation.
9) As shown in Figure_71), if you look at the Device Manager, you will find the USB High Speed Serial Converter is installed on the universal serial bus and USB Serial Port(COM?) is on the port (COM and LPT).
10) If the USB Serial Port value is set above COM10, use Exmons Pro 2005 after resetting the port number to fall within COM 1 and 9.
9.1 Concept of stationary battery measurement
In order to examine the extent of deterioration of the measurement materials such as stationary batteries that tend to increase their internal impedance as they get older, it is necessary to measure their voltage sags by an internal impedance, VIS (below impedance voltage) by connecting parallel current, IS, to the terminals of the measured objects such as stationary batteries so as to calculate the internal impedance/resistance value. A theory that uses the outcome obtained by such procedures to diagnosis the status of stationary batteries is well established and internationally recognized. (Refer to IEEE STD. 1188 & 484)
9.2 Concept of Stationary Battery impedance (internal resistance) measurement and IEEE Std. recommendation
9.2.1 Equivalent circuit of stationary battery and internal resistance factors
① 40% (Pole plate resistance): Electrochemical resistance typical to pole plates. (Changes according to the extent of corrosion of the pole plate)
② 25% (contact resistance): Resistance against contact points of the pole plate
③ 15% (electrolyte resistance): Resistance due to the ion conductivity of electrolyte (Varies by the measuring frequency)
④ 12% (contact resistance): Interconnect resistance due to poles and bus-bar. According to the degree of the pole plate corrosion, the deterioration will be progressed into① pole plate resistance (40%) and ③electrolyte resistance and capacitive reactance (Xc) will be changed according to the measuring frequencies.
9.2.2 The concept of internal resistance and IEEE Std. recommendation
The relevant stipulation of the IEEE Std. 1188/485 specifies that “As the heightened vale of the cell’s internal resistance indicates a major change in a cell’s characteristics, by measuring the internal resistance of cells, it is possible to check the problem of cells thereby recognizing the low-performance cells.”
In other words, as the stationary batteries’s equivalent circuit characteristics is R-L-C serial/parallel circuit, if we know the difference of the size of internal resistance (①②③++ +④), it is possible to evaluate the status of change in a stationary battery characteristics (deterioration)
9.2.3 Securing accuracy and discrimination while measuring (example) The high capacity (Ah) stationary battery has a very low internal resistance value around 10mΩ∼0.1mΩ and 10% of it, or 0.01mΩ is of extremely low value. Therefore it is important to fully understand the measuring methods and do it accurately. In addition, since it is necessary to measure the internal resistance of each cell in a floating charge state where UPS/Stationary battery power is impressed, it is compulsory to use a specially designed tester to measure the internal resistance value accurately.
In general, the internal impedance value expressed in “mΩ”, is the internal resistance value measured by the impedance measuring method recommended by the above IEEE Std. 1188/484.
9.3 The internal and interconnect resistance during Stationary batteries measurement
In order to measure an accurate internal impedance value of the stationary battery, it is necessary to locate the point A (-) as close as possible to the point B(+) terminal and always measure the same location. It is because that as the internal impedance value of the stationary battery is so minuscule, it is necessary to minimize the external influence from the surrounding environment (mainly, contact resistance)
Albeit minuscule, cables or bus bar used for interconnecting the stationary battery cell terminals also have resistance values so as the connecting lines (contact resistance). To measure the interconnect resistance to check the contact status of the stationary battery terminal and connecting lines, measure the point B and Point C. When interconnect resistance is extraordinarily high, it may lead to voltage sag, which can bring about a decrease in discharge capacity. Furthermore, it will produce a heat due to contact resistance of connection parts. So please repair the bad connection as soon as possible.
