Design and Function

In the standard version, 5 or 10 charge-discharge circuits are combined in one cabinet with a common power supply. Each circuit is provided with its own control unit and the respective power unit. Three-phase AC ensures the mains supply. GUBT25/50A12V can resolve the main power failure problem and continue with testing automatically after that.

The programmable control unit is the core of each charge-discharge circuit. It is a standalone microcomputer system for a data logging and precise control of analogue measured values. It also assumes the processing of stored test programs.

In the manual operating mode, it is possible to select one of the stored programs No 1-8, interrupt and terminate the program by pressing the respective button. Digital instruments for battery voltage and current are fitted on the front panel.

Automatic operating mode is made via host computer with GBTS106 party line host computer software.
Testing:


  1. C-20 twenty hours capacity

  2. Rc spare capacity (reserve)

  3. Cycling

  4. Life time period testing

  5. Charge acceptance

  6. Charge retention

  7. Water consumption.

Examples: Figure 2, figure 3, figure 4, figure 5.

The Programs

All tests programs can be split into steps, where certain operations must be executed under well-defined conditions. Each step is fixed in a program line.

Each program step is divided into columns and each column has a headline describing its function.

Column explanations:

Column: Label

Each program step can be labeled which is used for controlling of program executing.



Column: Operation

Each program step starts with an operator determining the function of the test circuit. The operator names are simple abbreviations of the respective functions (charge, discharge, ramp, cycle, pause, stop).



Column: Set value

As nominal values for this step may be entered current, voltage or resistance of power values.



Column: Term. condition

The termination values current, voltage, time, capacity, energy and temperature determine the end of a program step and thus the beginning of the next program step. In building of condition can be used logical operators AND, OR, NOT.



Column: Term. action

Possibilities for The Term. Action columns are:

  • GOTO label -transfers program control to the specified program step

  • NEXT -goes to the next program step

  • STOP -terminates program

Column: Abort condition

The values entered under this column may be the same as for the termination values. However, in this case, the program run will be terminated if one of these limit values is reached.

Column: Registration

The conditions for the registration are entered into the last column. These may be time intervals or changes in current, voltage, capacity, energy or temperature.
