GIBT300A36V, GIBT300A18V

The Gaus Industrial Battery Tester GIBT is designed for testing of industrial batteries in a way to meet any requirement, i. E. charge and discharge with freely selectable current, pauses and repetition of a test procedure as a whole or in parts (cycling) and the registration of the measured data. Testing is not limited to leadf-acid batteries, but it is possible to test all other types of electrochemical power sources.
Many of the standardized test programs use the current as nominal value. But voltage, power or resistance values may be used as well. A program step may be terminated not only after a specified time, but also when a certain voltage or Ah (or Wh) values is reached. For registration of the measured values, interval of time, voltage, amperhours, or energy (Watt-hours) are suitable parameters.

Each GIBT is provided with its own programmable control and power unit. The power unit is alternatively made in transistor technique or designed as an inverter. For smaller power requirements in the range of 100W to 5000W several charge-discharge units are combined in one cabinet with a common power supply. Each circuit is provided with its own programmable control and the respective transistor power assembly. GIBT for small nominal voltage and high current are preferably made in transistor technique. The discharge energy is converted into heat in power transistors and resistors. More powerful units are designed as inverters and the energy is fed back to the mains.

The programmable control unit is the core of each 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 No1-8, 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.

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.
