VoltMaxX™ HV  PATENTED
Controller, VCU and
DC/DC ALL-IN-ONE

IET VoltMaxX-LV controllers are designed to control 3-phases Permanent Magnet Synchronous Motor in low voltage battery powered applications. The product was optimized to be applied as powertrain controller for unskilled and professional use.

Features

The result is a small and powerful controller complete of:

  • DC/DC converter to provide 12V 250W for vehicle lighting and accessories
  • 9 digital I/O lines, fully configurable as input or output, with diagnostic
  • Redundant Throttle command capability
  • Proportional regenerative breaking
  • Very low quiescent stand-by mode

High level functionality as:

  • Crash detector (by an accelerometer sensor)
  • Detailed timestamp log for easier service
  • Single CAN port for diagnostics and firmware upgrade operations
  • Fully customizable torque curve maps
  • A dedicate processor for end-user custom applications
  • Optimized Flux Vector Control with improved Space Vector Modulation; high switching frequency operation (24kHz)
  • Accurate and high efficiency flux-weakening control with proprietary algorithm
