Application

• Battery pack in EV scooter
• EV battery pack
• ESS battery
• Fuel cell stack
• Redox Flow Battery(RFB)

Features

• With the multi-channel equipment of floating structure, the impedance can be measured at the
  same time. It can be measured in the state of battery module or pack with no necessity of separate
  disassembly.
• The each channel can be controlled independently or simultaneously.
• As many cells can be measured at the same time, the impedance measurement time per battery can be reduced.
• The detailed data density measurement, it could be used for both QC and development.
• Even though it is the high-voltage equipment, it is highly portable.
• It is compact size as multi-channel system, weight is 6.6 kg(4ch). Easy USB 2.0 connection to a PC.
• Automatic equivalent circuit searching and various impedance analysis functions are possible using ZMAN impedance analysis software.(No license requirement)
• Fine setting is available by subdividing the frequency to fix to 65535 per decade when fixed frequency experiments.

Software

• 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).
