  응용 분야

The BZA1000 Battery Impedance Analyzer, which covers a broad range of battery test functions ranging
from DC voltage (up to 1000V) and impedance test (500uΩ ~ 50Ω), is an ideal test tool for performance
testing of individual stationary batteries, battery banks and ESS(Energy Storage Systems).

The BZA1000 is designed to measure battery impedance, dc and ac voltage, ac current, frequency and
battery temperature. There are several technique available such as galvanostatic EIS, HFR, Rs-psuedoRp
measurement Voltage-Temperature monitor etc. This shows real time information including related plot
formats. With galvnostatic EIS, Nyquist plot and Bode plot is provided in real time. And High Frequency
Resistance (Cs-Cp vs time and Zre-Vdc vs. time plot) and Rs-psuedo Rp measurement (Cs-Cp vs time
and Rs-psuedoRp vs time pot) is proviced. With these kind of informations,it is easy to see changes in the
Rs and Rct values that correlate to the battery's state of health(SoH) and state of charge(SOC), allowing
user to evaluate battery performance.

EIS data from BZA1000 can be analyzed with ZMAN impedance analysis software by automatic model
searching and automatic fitting. Proper model library for user’s batteries can be grouped to minimize
the analysis time.


  • Impedance measurement of battery, battery pack& ESS
    (energy storage system)


  • Real time plot with monitoring channel status following technique
  • Open circuit voltage measurement, battery temperature measurement possible using optional
    PT100 sensor.
  • Multichannel operation is available with different models in network
  • Independent impedance data analysis with modeling & fitting, ZMAN™ software compatible data
    format (No license requirement)
  • Fine setting is available by subdividing the frequency to fix to 1000 per decade when fixed frequency experiments.


  • Independent examination from the PC is available after the test starts.
  • A various scope of parameters for the test is adjustable that are used in the test
  • Even if you lose connection of BZA and PC, if the device is powered on, the device will continue experiment . Memory can be saved after the connection recovers.
  • Data is saved in the form of binary format that is compatible with the ZMAN software thus can be transformed into the text(CSV, TXT).
