2. Batscan is an advanced monitoring system for back-up power batteries. Batteries are being used in many different areas as an alternate power source in the event of an power outage in the public power grid.
3. If you think you can solve your UPS-problems by buying new batteries… Think again. Because approximately 2% of the new batteries are faulty by delivery.
4. A Battery compares to a chain. The battery must be able to supply the load with enough current (Amp) and the chain must carry the weight of the load (kg). An open cell in the battery is like a rusty link in the chain that eventually breaks, it doesn't matter that all the rest of the links are fine, the chain will be useless anyway because of one broken link. The load passes trough all cells in the battery. If one cell breaks the whole battery will collapse.
5. Measuring a battery’s total voltage does not give any information about the state of health of individual battery cells. An increased cell voltage results in decreased voltage over remaining cells.
6. AT&T’s primary requirement for a Battery Monitoring System was safety. First, the system could not pose any hazard to a person coming in touch with any parts of it. Second, a short-circuit must not result in heat release or spark formation. Batscan complies with these requirements due to the fact that all connections to batteries are done through high value resistors which limits short-circuit current to less than 1mA. Batscan was developed taking highest possible safety into consideration . All battery connections have integrated protective resistors.
7. The real workhorses in the Batscan system are the measuring modules. They use a dual processor digital signal processing (DSP) technique to restore the DC signal from the batteries with high speed oversampling digital to analog conversions followed by a property filtering algorithm. An internal transformer with reinforced isolation (6kV test voltage) separates the analog side from the communication bus.
8. The modular design allows for flexible configuration and system layout. The modules can be mounted directly on the battery, inside the wire conduits, grouped together in larger enclosures or even be placed in a 19" rack cabinet. For large strings batteries, a common configuration is wall mounted IP65 enclosures with 4 to 10 modules placed next to each battery string. The modules are interconnected with modular cable and plugs, for longer distances a high quality DeviceNet cable is used.
9. The only possibility way to detect a fault in the battery before it can cause a power failure is by continuously monitor each battery cell (or group of cells). However, this must be done without introducing any additional risk factors.
10. Everytime your system calls for UPS-power the batteryrace is on. If You use our competitors low-tech systems You cant follow the batteryrace.
11. With Batscan You will get the full picture and You will know which battery You need to replace before the next race begins.
12. In a battery with hundreds of blocks, it is very difficult to manually measure the individual voltages. Batscan continuously measures all block-voltages and collect data 250 times every second and shows the result in a bar graph diagram. A out-of-limit-value is emphasized with red or blue color marking and triggers an external alarm.
13. Batscan is not just a alarm-system, it’s a system that will tell you if the batteries are ready to take the load or not.
14. The Graph Window is typically used by service personnel to investigate a battery's response to a power failure event or a discharge test. The content of the Graph Window can be printed or saved as a picture for documentation.
15. Batscan can present all measurements in a graphical form, either as a snapshot at a specific time (record) or as trend over time. The graphical form makes it possible to get a good overview of thousands of values simultaneously and deviations from normal is easily detected without one having to be a specialist on batteries.
16. All our customers share the common trait of the emphasis they place on operational reliability, and realizing that battery monitoring is an important factor for this to be achieved. Some examples of Batscan users are:
17. Batscan is ideal for monitoring solar panel applications.
