In order to achieve these goals, various solution approaches must be considered. This includes not only pure battery solutions, but also hybrid energy systems as well as other technologies and techniques such as fuel cells or solar energy systems. When using a hybrid energy supply, different power sources can be used equally to achieve efficient output power. This can significantly improve both energy consumption and vehicle durability. But there are still many technical challenges in designing such systems: The desired power range must be identified; the optimal hybrid (batteries plus motor system) must be found; an intelligent control system must be developed and implemented; all component testing must be performed; and ultimately, the system must be optimized according to the application criteria. 

We believe that an intelligent combination of electromechanical and hydraulic drives allows mobile machine operators to benefit from both worlds while improving the overall performance of their equipment. By leveraging the individual strengths of each technology, such as improved energy efficiency in electric drives and increased versatility in hydraulic systems, operators can create a more efficient solution tailored to the specific needs of their application.

REFUdrive offers drive solutions for this that are suitable for both low speed and high speed applications. By using permanent magnet or asynchronous motors in combination with powerful inverters, an optimal power package is achieved that achieves high efficiency and performance in use. In addition, it is possible to develop individually tailored solutions that are specially adapted to the needs of the respective market. 

In order to make electric commercial vehicles even more sophisticated and economical, work must continue on innovative solutions. REFUdrive has therefore made it its goal to drive technological advances and provide customers with the best possible support in the introduction of electric solutions for commercial vehicles. Our broad portfolio of products enables a wide range of options for implementing this vision - from the design of new drive systems to the integration of component technology and the optimisation of existing systems.

In addition, electric buses require less space because components such as the fuel tank, transmission, engine and axles are eliminated or significantly reduced. As a result, passengers have more space to sit and can get on and off more easily. Electric buses also offer a number of other benefits that can help cities become greener and more sustainable. For example, electric buses can be equipped with advanced technologies such as automated driving systems that can further reduce emissions by optimising traffic flow. In addition, electric buses offer more efficient energy use compared to conventional diesel vehicles, as they have fewer moving parts to maintain over time. This means that cities can save on operating costs in the long term while meeting their environmental targets. Finally, electric buses also allow for better air quality as they eliminate the toxic fumes of diesel engines; this has proven to be particularly beneficial for those living near major roads with high traffic volumes.

REFUdrive is an ideal partner for the electrification of public transport, such as e-buses. We offer a wide range of complete drive systems and components specifically designed for this purpose. Our products offer high performance, reliability and safety. The REFUdrive inverters, on-board chargers and motor controllers make electric buses more efficient and reduce their operating costs. In addition to reliable technology, we also offer comprehensive know-how in the field of bus drive systems.

The fact that waste collection routes can be planned in advance also makes electrification more feasible, as it allows for an accurate prediction of the required range. As these vehicles are used intensively on a daily basis, operating costs are more important than purchase costs. With electric vehicles, these operating costs can be significantly reduced due to the elimination of harmful exhaust gases and particulate matter from the air. An additional advantage is regenerative braking, which significantly reduces brake pad wear.
