Features

  • Equipped with D&V’s PMM-10 10MHz power analyzer as well as D&V’s SV-PRO software.
  • Flexible control scheme supports wide range of e-Axle configuration from single motor with open differential to dual-motor with Dual Power Inverter Module (DPIM).
  • The speed of each load motor can be controlled independently to simulate turning or special test requirement such as differential break-in.
  • Overall system efficiency of 50% thanks to energy recuperation capability within the system which can reduce energy consumption significantly.
  • Automated LV, HV and fluid connections as well as spline engagement whose axial position can be programmed.
  • Robot ready and capable of executing the entire EOL test automatically including making electrical and mechanical connections without human intervention and perform air pressure fluid evacuation at the end.
  • Pre-programmed comprehensive EOL test which checks not only basic performance of the DUT but also e-Axle specific measurements such as back-lash of the gear train as well as NVH characteristics.
  • Part number, test report and statistics file can be selected and queried remotely by MES through TCP/IP.
