A flexible hybrid solution

AVL 48V Mild Hybrid Solutions

At AVL we have spent more than fifteen years gaining extensive experience with 48 volt technology, for both gasoline and diesel engines. Based on our system integration competence, we have expertise in every element of modern powertrain engineering, from the engine and transmission to power electronics, batteries, controls and e-machine.

Our competence in the modular upgrading of existing concepts into mild hybrids enables us to maintain the optimal balance of driveability and performance with the lowest CO2 and emissions. This is all balanced with low cost of ownership and CO2 fleet averages.

This concept has proven successful with diesel and gasoline 48 V P2 hybrids. Both projects demonstrated how to combine real-life fuel efficiency with low emission levels and attractive driving performance.

AVL ICE-based Powertrain Solutions

The 48 V hybrid is one of the most effective examples of balancing fuel economy and low emissions with attractive performance at reasonable cost. Our approach to these hybrids includes:

  • Enhanced start-stop and recuperation
  • Load levelling
  • Electric torque assist, sailing and coasting
  • Driving purely electrically
  • CO2 and emission reduction
  • Optimized exhaust gas after treatment
  • Electric power/energy management
  • Electric supercharging (optional)
