Electronics and Software

BMS Electronics

  • Solid state power electronics provide electronic fusing capability
  • BMS has the ability to rapidly detect and disconnect during a system level short circuit in under 75 microseconds

Software

  • Accurate SOC estimation and temperature rise awareness with in situ thermal model
  • Complete cell control (voltage, temperature, battery health, and current flow)
  • Advanced active cell balancing measures and controls cell voltages within cell banks and removes any extra energy from cells with a higher voltage


Active Voltage Control (AVC)

  • Accelerates charging with continuous control of alternator voltage


Data Acquisition System (Optional)

  • Integrated DAQ system for warranty and diagnostics
