    • Battery 48 V (Li), DC-DC converter, battery 12 V (Pb)
  • Electric motor: power usually max. 15 - 20 kW
    • It is auxiliary system, it increases power and torque of the whole drive.
    • It helps compensate problematic areas of the ICE efficiency map.
    • It compensates torque generation delays from ICE.
  • It does not allow a purely electric driving.
  • Recuperation
