In addition to the 4-wire measuring technology, a 6-wire arrangement is also provided to facilitate the wiring.
The measurement module is protected by an aluminium housing which can be mounted by 4 screws. It is remotely controlled via RS232 communication interface and powered by a separate power supply.

Properties

  • Switchable resistance range allows welding tests.
  • 3-parameter measurement within 0.4sec
  • Measuring battery voltage with high accuracy (±1mV for cells)
  • Measuring the battery internal resistance (ohmic part) at 2 frequencies (10Hz, 1kHz)
  • Test connection in 4-wire technology or in 6-wire technology with compensation current
  • Measuring temperature with temperature compensation of the 10Hz measurement
  • Cycle time can be further reduced by parallel operation

Multiplexer BMUX15/4Multiplexer BMUX15

The BMUX 15/4 is a multicontact switch (multiplexer) in four-wire-technique for impedance and voltage measurements of multiple battery cells. It switches up to 15 cascaded or up to 8 seperated cells onto one impedance meter (BIM1, BIM2, BTC1).

The BMUX 15/4 is controlled via USB or RS232 interface with a simple protocol or via graphical user interface with a PC.

 

 


BIM1 and BIM2

The BIM-1 and BIM-2 are economical, easy to use and compact Battery Impedance Meters. Batteriemessgerät BIM1They combine the functions of a battery tester and of a battery analyzer and allow a quick test of battery cells and battery modules independently of the battery technology.

The results ​​are communicated to a PC via USB interface which also provides electrical power. Operation is via a graphical user interface (GUI) which operates and displays the results; alternatively a programming interface can be provided.

Ambient conditions (temperature) can be measured via a second input (BIM2 only).

BIM-HV

The BIM-HV is the world’s first instrument to measure impedance and voltage in battery systems up to 800V.Batteriemessgerät BIM-HV

The instrument combines the functions of a battery tester and a battery analyser and enables quick testing of batteries independent of technology.

The instrument measures the spectral impedance between 1Hz and 1kHz plus the voltage of cells, modules and systems. It determines the battery states (SoH, SoC) and the operating parameters such as AC and DC impedance. It enables capacity measurements without elaborate discharging methods.

The results ​​are communicated to a PC via USB interface which also provides electrical power. Operation is via a graphical user interface (GUI) which operates and displays the results.

The instrument is suited for trouble shooting in development and production, for operational analysis in trials and for quick diagnosis in service and maintenance.
