Intelligent Battery Sensor (IBS)
 

  • Scalable power class of up to 1.8 kW (passive air cooling) and 3.5 kW (liquid cooling)
  • Bi-directional energy transfer between 48 V and 12 V power systems
  • Efficiency rate up to 97 %
  • Supply to special load systems, e. g. for electromechanical power steering

 Customer Benefits

The converters enable new applications such as stop / start and idle cruising, whilst ensuring the supply of fuel-efficient power loads such as electrical power-steering actuators. Additional, cost-effective systems such as recuperation, electric boost and creep can be implemented with the use of the products. The average harvested electrical power for recuperation in WLTP is up to 350 W when using a 10 kW electric machine. This is equivalent to a fuel-saving of ~ 0.5 l / 100 km.
