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