Abstract:

At the Swiss Federal Institute of Technology (ETH) Zurich, a reduced scale solar vehicle is going to be designed and built in order to apply hybrid and parameter-varying control techniques. Applications could include the investigation of speed and torque control, control regarding the power management and others. This vehicle shall represent an autonomous vehicle at a remote place and has to be able to drive off-road over bumps and holes, while the electrical hardware is well protected. An important aspect for the vehicle’s design is its modularity. Since a typical application is not yet fixed, the ex- change, addition or modification of the vehicle’s hardware should not require a complete redesign. In this semester project, the power supply for the vehicle is designed. The vehicle gains its energy from a photovoltaic solar module, a rechargeable battery and power peaks and sags are buffered by ultracapacitors. In a first part, theory on the three different power modules is elaborated and practical considerations for the design of the modules are explained. Based on this, the components and design of the solar module, the battery and the ultracapacitors are selected. In a second part, two different concepts for the energy management hardware are developed and compared to each other, especially regarding their efficiency. Furthermore, a model of the hardware is created in order to examine management techniques that should increase the system’s lifetime and efficiency.
