Tittle:
Power drive for hybrid vehicles
Summary:
A German university developed a power drive for hybrid vehicles which improves the topology for the realization of such a drive system. Due to continious operation of the combustion engine in the optimum working point, the invention has a higher efficiency. The university offers a license agreement as well as a technical cooperation agreement.
Description:
The main advantages of electric drives in passenger cars, in particular the wheel, are the driving dynamics and the local operation without emissions. However, the range of these road vehicles is limited due to the limited battery capacity. Therefore, many electric vehicles use a so-called range extender to increase the range, but the efficiency of the range extender is also limited due to the plurality of converter stages.

A German university invented a power drive for hybrid vehicles that has the task to integrate a small combustion engine efficiently into the drive train and to produce a real single wheel drive, at least for the front wheels. The crankshaft of the internal combustion engine is accessible on both sides. I t opens on both sides into the rotor of an electrical machine. The stators of the two electrical machines lead to the respective wheel via a fixed gearing. The machines are connected via slip rings. Since both electrical machines permit a free speed adjustment of the internal combustion engine, the manual transmission can be omitted and a light and compact drive unit is produced. Due to the differential speed-dependent power indication of this topology and its energy management, the engine can always be operated at the best operating point. It charges the battery and simultaneously drives the front wheels. The torque can be distributed individually to the front wheels. The rear wheels can remain powerless, driven by an electric motor or individually via two electric motors.

This technology offers a cost-effective topology for the realization of a hybrid vehicle. Due to the continuous operation of the combustion engine at the optimum working point, the power drive has a higher efficiency. The concept allows the drive of only one axle, but also a real all-wheel drive, whereby all four wheels can be individually controlled. An implementation with more than two axes is also conceivable.

The university offers a license agreement as well as a technical cooperation agreement to companies that are interested in transforming the invention into a market-ready product. This technology offer addresses the automotive sector (passenger cars or utility vehicles).
Advantages and Innovations:
The main innovative idea about his technology is to optimize the topology of a hybrid vehicle. Due to the continuous operation of the combustion engine in the optimum working point, the invention has a higher efficiency than conventional hybrid drives. Other competitive advantages are:
- Simple setup
- Robust
- No shift gearbox necessary
- 4 wheel drive available
- Individual control of all wheels possible
