The task of testing an aircraft’s Nickel-Cadmium batteries is complicated and involved because of the high number of cell voltage readings that need to be taken during testing.  Taking voltage readings from all 20 cells in the typical nickle-cadmium aviation battery multiple times is laborious and error prone, but must be done to properly estimate the condition of the battery under test.

In order to simplify this process, JFM Engineering offers the BTAS-16 system.  The BTAS-16 system provides complete automation of the battery testing process; taking battery and cell readings while assuming control of the Charger-Analyzer used during testing.  The BTAS-16 system will greatly improve the accuracy and efficiency of your battery shop.

How complete is your battery testing process? 
Do you take periodic cell readings?
Can you easily compare new test results with prior ones? 
What kind of an audit trail do you have?

The BTAS-16 addresses all of these questions!

With the BTAS-16 you can:

New BTAS-16K Software!

The original BTAS-16 software has been completely rewritten, from the ground up, as the all new BTAS-16K software. The BTAS-16K software is designed to take advantage of all that the modern Windows environment has to offer. While the BTAS-16K software retains all of the same functionality as the original BTAS-16 software, it also offers several improvements:

  • Complete Integration With JFM’s Intelligent Charger-Analyzers
  • Combination tests, which transfer between Charge and Discharge modes automatically.
  • Cell level analysis, which will stop a test in the event that a cell exhibits a negative delta voltage during charge.
  • The Ability to Pre-Program Intelligent Charger-Analyzers Based on Battery Model Profiles Saved in the BTAS-16K Data Base
  • Faster Operation and A More Responsive Graphical User Interface
  • Improved Plotting Graphics and Battery Reports
  • Status Updates by Email or Text Message
  • Automatic Updating Through the Internet
  • Built-In Ability to Export Reports to PDF, Excel or Word

Along with these Improvements, we will also be rolling out further upgrades to the BTAS-16K software through it’s Automatic Updating feature down the line.

New Accessories for Testing Lead-Acid Batteries

2BC-1-5002BC-2-500New Software and Accesories are now available to allow the analysis of Lead-Acid Batteries under test using the BTAS-16

Although the BTAS-16 was initially designed to facilitate the testing of Nickel-Cadmium Batteries, the BTAS-16 now has been updated to appropriately color code bar graphs specific to Lead-Acid Batteries test results.  A new Interface Box with connections to the BTAS-16 plugs into the Battery Cable and facilitates the reading of the voltage of the batteries by the BAS16 software. Once the BTAS-16 recognizes the presence of this interface, it makes available a dialog to identify the battery as Lead-Acid and to show the nominal battery voltage (12V, 24V, etc).

During charge, the bar-graphs and reports will show how the battery voltage rises until it reaches the float voltage point at which time the current will diminish as the battery charges up. With this system, it is possible to identify when a battery has reached the end of charge or if the battery requires a high level of current to maintain the programmed voltage (at the Charger).

During Discharge (Capacity Test), bar-graphs and reports will display the voltage profile that can be used to determine if the battery meets the required discharge performance or it it falls short of the established discharge time.

An additional Accessory, called the Four Battery Cable, is available for testing of small batteries and battery packs of any chemistry, where cells are not accessible. Once the BTAS-16 recognizes the presence of this interface, it makes a available a dialog to identify the battery type as Nickecl-Cadmium, Lead-Acid (or other) and record the number of cells, if Nickel-Cadmium, or the nominal battery voltage if Lead-Acid.
