Abstract
This paper summarizes the basic assumptions that led to a thesis which investigates the use of high efficiency solar cells used by solar cars, with the main aim of minimizing energy consumption in such a vehicle. A solar car is special in the way that there is not only energy consumed, but also generated. This energy should be used in the most efficient way, for example with the use of a combination of different energy storages, such as high efficiency batteries and super capacitors.
Highlights
In the 20th century there was a rapid development in industry and new computer technology
The basic system arrangement of a solar car would consist of three main components – the motor, where electric energy is transformed into mechanical kinetic energy, the battery, and solar cells that transform energy in the light into electrical energy
Considering the high solar irradiation of 1000 Wm-2, a solar cell efficiency of 30% and an area of 1m2, the possible solar energy that can be used these days transformed into electrical energy can be calculated with Equation : Plim E Ac
Summary
Whereas a regular capacitor consists of conductive foils and a dry separator, the Super capacitor crosses into battery technology by using special electrodes and some electrolyte. Whereas the electro-chemical battery delivers a fairly steady voltage in the usable energy spectrum, the voltage of the super capacitor is linear and drops evenly from full voltage to zero volts. On the other hand the super capacitor has a very high specific power that can be approximately ten times higher batteries in this comparison chart. Rather than operate them as a main battery, super capacitors are more commonly used as memory backup to bridge short power interruptions. Another application is improving the current handling of a battery. The super capacitor does not require a full-charge detection circuit. A nickel based battery discharges about 10 percent during that time
