Familiarize yourself with the possibilities of modern battery measurement technology using electrochemical impedance spectroscopy battery testing:

  • What test procedures are there for determining the battery condition (SoC, SoH) and what do they do?
  • Which measuring methods are useful in design & development, production and service operation?
  • What can the battery cell impedance contribute to the quality of battery systems?
  • We offer practice-oriented training; please contact us.

    BRS Messtechnik GmbH is an expert in battery impedance testing. Batteries and battery systems can be tested quickly and efficiently with our compact battery impedance test equipment, independent of the battery technology.

    Our battery impedance tester are universal tools for professional battery users and enable:

    • standard battery impedance tests (voltage, internal resistance, capacity)
    • battery analysis (comparison, trends, modeling)
    • diagnosis (state of charge, state of health, integrity)
    • recording of ambient conditions (temperature)

    Our offer includes:

    • Professional battery impedance test equipment
    • Development of customized battery impedance test technology
    • Consulting and engineering for battery cell impedance measurement technology

    For Development

    Complete characterization

    Batteries have to be qualified for specific applications, requiring the measurement of all relevant battery parameters:

    • Voltage
    • Spectral impedance
    • Capacity
    • Temperature
    • Model parameters

    An integrated fully automatic calculation of the model parameters facilitates the analysis. The commonly used cylindrical cells (18650/ 21700) can be fully characterized with a compact and complete measuring system.

    Recommended instruments: BTC1, CTA (Cell Test Adapter)

    Quality within 0.4 seconds

    For incoming inspection of large quantities of cells, measurement speed combined with in-depth testing is important.

    Our compact instruments can be easily integrated into production lines for batteries. Within just 0.4 seconds they measure:

    • Voltage
    • AC impedance
    • DC impedance

    For high quantities, the 5-channel MBT-X5 is recommended; for shorter cycle times, the measuring frequencies can be adjusted.

    Recommended instruments: MBT family

    For Diagnosis

    Battery quality in 1 min

    The residual capacity (SoH) is important for battery diagnostics, e.g. for determining of reuse (second life). The comparison of impedance spectra provides information about the battery condition in just 1 minute. An integrated analysis algorithm reduces the complex data to just 1 essential parameter for easy evaluation.

    • Diagnosis
    • State-of-health
    • Second life

    Recommended instruments: BIM2B, BIM-HV-B
