Model for selecting the cooling system components of an electric vehicle

Vse več podjetij se pri reševanju in načrtovanju inženirskih sistemov nagiba k uporabi programa Simulink znotraj programskega okolja Matlab. Ta se uporablja za izdelavo modelov, v katerih lahko simuliramo resnično stanje ali iščemo optimalne rešitve za kasnejšo realizacijo sistema. Izhajali smo iz fizikalno že urejenega modela hladilnega sistema,namenjenega hlajenju električnih komponent, ki omogoča spremljanje temperatur v odvisnosti od različnih parametrov. Izdelali smo model, ki bo s pomočjo simulacije omogočal določevanje koeficienta toplotne prestopnosti in velikosti naše črpalke glede na padec tlaka na komponentah v hladilnem sistemu električnega avtomobila. Rezultate simulacij smo primerjali z meritvami na električnem vozilu, kjer smo merili temperaturo in tlak pred in za vsako komponento.More and more companies employ the use of the Simulink programme, which is a part of programme environment Matlab, to solve and plan engineering systems. The programme is used to develop models in which we can simulate reality and find optimal solutions for the later realisation of the system. Our basis was an already made model of cooling system, used to cool electric components, which allows us to monitor the temperature in relation to various parameters. We made a model, which allows us to predict coefficient of thermal conductivity and the size of the pump based on the decrease of pressure in the components of cooling system of an electric car. We further compared results of simulations with experimental results, where we measured temperature and pressure before and after each component
