Hybrid drive solutions

Hybrid drive solutions for commercial vehicles

Hybride Antriebssysteme bestehen per Definition aus zwei Antriebskomponenten und zwei Energiespeichern. In unserem Fall ist einer der Energiespeicher eine Batterie, die aber in der Kapazität deutlich kleiner dimensioniert sein kann als bei rein batterieelektrischen Lösungen. Je nach Anwendung kommen dafür auch sogenannten SuperCaps in Frage. Bei der Hybrid-Topologie unterscheiden wir in serielle und parallele Hybride. Beim Parallel-Hybrid sind Verbrennungsmotor und E-Maschine mechanisch gekoppelt und lösen so die Antriebsaufgaben. Beim Seriell-Hybrid dient ein Verbrennungsmotor mit E-Generator zur Erzeugung elektrischer Energie, während das gesamte Fahrzeug dann elektrisch angetrieben wird.

Recuperation

up to 80% of the braking energy is reused

Downsizing

Reduced fuel consumption, significantly improved exhaust gas values

More power

Higher peak power achievable for higher vehicle performance

 

Main potentials of hybrid drive solutions

 

Hybrid drive solutions have a clear advantage when purely battery-electric solutions are still economically justifiable but do not provide the required range in terms of kilometers or working hours.

 

Parallel hybrids require overall minor modifications to the vehicle compared to pure combustion engine solutions. In addition, depending on the system design, these also offer the advantage of increased redundancy. Depending on the application, this can be a key factor.

 

Serial hybrids tend to have better overall efficiencies than parallel hybrids but require fully electrified drives for propulsion, traction, and functional drives. Due to our multi-energy concept, it is relatively easy to develop serial hybrids further into hydrogen-based solutions in a later step.

 

In addition to charging the built-in battery in the hybrid vehicle via the internal combustion engine, a possible charging function from the public power grid can also be added as an option.

Application areas for hybrid drive solutions

 
  • Hybrid drive solutions are equally suitable for working machines, commercial vehicles, and ships.
  • Serial hybrids are particularly suitable for applications with high peak powers at rather low to medium continuous power levels. A further field of application arises if a transition to hydrogen technology is planned as a second step after the hybrid with a combustion engine.
  • Parallel hybrids are mainly suitable for applications with high continuous power or when high redundancy is required. For this purpose, we offer solutions for example based on asynchronous (AC induction) motors.
