Abstract

U uvodnom dijelu obuhvaćen je problem sveopćeg zagađenja okoline u kojoj živimo, s posebnim osvrtom na veliki doprinos povećanog opsega prometa, u kojem je još uvijek prevladavajući konvencionalni pogon, koji kao izvor energije koristi fosilna goriva.
Prikazane su mogućnosti koje nudi primjena alternativnih vrsta pogona i objašnjeni prednosti i nedostaci svake od njih. Obzirom da je električni pogon trenutno najpogodniji za uvođenje u svakodnevno korištenje, njemu je pridana posebna pozornost. Nakon kratke povijesti razvoja vozila na električni pogon, detaljno su prikazana osnovna svojstva tog pogona. Objašnjene su različite vrste pogona i prikazane prednosti i mane u odnosu na vozila na konvencionalni pogon, te dana usporedba s ostalim vozilima na alternativne pogone. Uz prikaz trenutnog stanja na tržištu takvih vozila, uspoređena su i različita alternativna goriva, te opisana predviđanja sudbine njihove upotrebe u budućnosti. Obuhvaćena je i zakonska regulativa koja ohrabruje korištenje alternativne pogone kombiniranjem različitih ograničavajućih i poticajnih zakona i propisa.
Trenutno stanje razvoja električnih vozila nudi mogućnosti velikom broju različitih subjekata. Predložena je metodologija analize parametara vožnje električnih vozila, koja omogućuje pregled različitih karakteristika pojedinih vozila, kao i usporednu analizu vozila temeljenu na rezultatima osnovne analize svakog od njih. Obrazloženi su razlozi koji uvjetuju proces analize, a cijeli proces je zamišljen kao neovisan od izvora podataka.
Na temelju metodologije je izrađen program, kojim je trebalo provjeriti njenu ispravnost. Obuhvaćena su različita razdoblja u kojima se prate promjene podataka, tako da se rezultati mogu promatrati na razini jedne vožnje (odnosno zabilježenog događaja), dnevno ili u nekom razdoblju. Podaci se analiziraju korištenjem unaprijed definirane konfiguracijske datoteke i pohranjuju u bazu podataka. Rezultati dobiveni procesom osnovne analize mogu se iskoristiti za usporednu analizu istog ili različitih vozila na električni pogon u nekom razdoblju prema zajedničkim zadanim kriterijima.
Program je primijenjen na pravim podacima prikupljenim tijekom 1994. i 1995. godine u sklopu programa za primjenu i razvoj električnih vozila na University of South Florida. Analizirano je pet vozila, njihove karakteristike su uspoređene pomoću programa i prokomentirane u odnosu na uobičajene zahtjeve (domet, brzina, potrošnja i si.). Na kraju je prikazana primjena metodologije i programa na drugačiji tip procesa.

Abstract (english)

The introductory part is dedicated to the problem of general pollution of the environment that we live in, with special retrospection on considerable influence of the enlarged traffic, with conventional motive-power using fossil fuels as the source of energy still prevailing.
Furthermore the options connected with the use of alternative types of motive-power are presented and the advantages and shortcomings of each of them are explained. Considering that the electric motive-power is at present most adequate to be introduced for the everyday use, particular attention has been accorded to it. Following a brief history of the electric vehicles development, principal characteristics of electric motive-power are presented in details. Explanations concerning various types are followed by comparison of advantages and shortcomings compared to the conventional motive-power vehicles, as well as by comparison to other vehicles using alternative motive-power. Next to the presentation of the actual situation on the market of such vehicles, various alternative fuels are compared and the account of predictions of their future use is given. Also comprised is legal regulation encouraging the use of the alternative motive-power through a combination of different restrictive and encouraging laws and measures.
Present state of the electric vehicles development offers the possibilities to a large number of different subjects. Such methodology of electric-vehicle-driving-parameters analysis is suggested that enables overview of different characteristics of particular cars, as well as comparative analysis of the vehicles based on the results of the basic analysis of each vehicle. Explained are further the reasons which influence the process of analysis, while the whole process is conceived as an independent source of information.
Based on the methodology a program has been developed to test the methodology’s accuracy. Within, different periods are comprised, in which the changes of the data are monitored, in order that the results can be observed on the level of one drive (recorded event), daily or during certain period of time. The data are (is) analysed using the in advance defined configuration file and saved in the database. The results of the basic analysis process may be used for the comparative analysis of the same or of the different electric vehicles within a certain period according to the commonly set criteria.
The program is applied to the real data collected during 1994 and 1995 within the electric vehicles application and development program at the University of South Florida. Five vehicles have been analysed, their characteristics have been compared through the program and commented in relation to the usual demands (range, speed, consumption etc.). Eventually the application of the methodology and the program to the different type of process is shown.
