Electric vehicle modelling for real application

Electric vehicles are often mentioned as part of the solution to the problems of contemporary society such as air pollution, climatic changes, smog and noise in the urban environment, limited fossil fuel resources and their rising price. However there are several shortcomings which limit their wide application. The main of those are the high price and mass of the battery, which usually translates to low capacity battery. In the present article a calculation and an analysis of the possibility of a limited capacity battery application for the urban usage is given. Such a battery would have a lower price and its capacity would fulfill the needs of the majority of the average users which use the car for everyday short urban transfers. In the first part of the article a comparison between the standard driving cycles with a real route on the streets of the city of Rijeka was done. The real data have been collected with a GPS device. The driving speed and the road slope were calculated. With the data obtained, the required driving energy was calculated for different vehicle specifications: lower or higher mass, with or without the regenerative braking system. The influence of the hills in the route on the driving range was evaluated.
