Hybridantriebsaggregate

Hybridantriebsaggregate, often referred to as hybrid powertrains, are systems that combine two or more distinct power sources to propel a vehicle. The most common configuration involves an internal combustion engine (ICE) and an electric motor. This integration allows for improved fuel efficiency and reduced emissions compared to traditional ICE-only vehicles, particularly in urban driving conditions where regenerative braking can recapture energy.

The electric motor can assist the ICE during acceleration, allowing for a smaller and more efficient ICE. It can also power the vehicle solely on electric power for short distances, which is beneficial for reducing local emissions and noise pollution. Energy is stored in a battery pack, which is recharged by the ICE and through regenerative braking.

There are several types of hybrid powertrains, including parallel hybrids, series hybrids, and series-parallel (or power-split) hybrids. In a parallel hybrid, both the ICE and electric motor can directly drive the wheels. In a series hybrid, the ICE acts solely as a generator to charge the battery or power the electric motor, which then drives the wheels. Series-parallel hybrids offer the flexibility to operate in either series or parallel modes, optimizing performance and efficiency across a wider range of driving scenarios. The complexity and cost of hybrid systems can vary depending on the chosen architecture and the size of the battery and electric motor.
