Hioki SS7081-50 Battery Cell Voltage Generator

The Hioki SS7081-50 a 12-channel battery cell voltage generator that delivers power supply, electronic load, and DMM functionality in a single package. The system's simple architecture makes building an environment for validating BMS (*1) functionality safer, more affordable and more productive than ever before. 


Hioki SS7081-50

Building an environment for validating BMS functionality has never been easier.

Introducing a 12-channel battery cell voltage generator that delivers power supply, electronic load, and DMM functionality in a single package. 
The SS7081-50’s simple architecture makes building an environment for validating BMS functionality more affordable and productive than ever before. 


Hioki SS7081-50Safer than using actual batteries and separate power supplies.

  • Simulate cell behavior in individual channels, with 12 channels per SS7081-50 unit
  • Build a large-scale module environment with a series voltage of 1000 V (5 V/channel × 200 channels = 1000 V)
  • Simulate cell anomalies that would pose the risk of fire if using actual batteries
  • Simulate open-wire malfunctions between channels and the BMS
  • Simulate cell shorts

Hioki SS7081-50

High-accuracy, high-precision output and testing.

  • Simulate cell behavior using high-accuracy voltage output
  • Take advantage of cell balancing from -1 A to 1 A with two-quadrant output voltages
  • High-accuracy, high-precision voltage and current measurement
  • Measure minuscule currents using the 100 μA range (for BMS dark current and cell balancing circuit leakage current)


Hioki SS7081-50 
 

Simplify evaluation with the bundled PC application.

  • Control up to ten SS7081-50 units
  • Automate testing by creating sequences of the simulated states you wish to reproduce
