Abstract
Na temelju pretpostavljene potrošnje energije električnog vozila s željenim dometom od 250 km izvršen je proračun i dimenzionirana je baterija koja zadovoljava postavljene zahtjeve. Bitni parametri tj. kriteriji pri dimenzioniranju baterije su njena specifična energija i specifična snaga. Kako bi se osiguralo pravilno hlađenje i održavanje željene temperature baterije, izvršen je analitički proračun topline, a zatim i numerički pomoću programskog koda napisanog u MATLAB-u čime su dobiveni precizniji rezultati. Za daljnje razumijevanje ponašanja topline i pravilno modeliranje sustava hlađenja korištene su CFD simulacije na CAD modelima koje približno prikazuju stvarnu situaciju strujanja fluida i odvođenja topline. Optimizacijom geometrije usisne cijevi se minimizira pad tlaka čime je daljnje poboljšano odvođenje topline zrakom. Nakon završenog proračuna potvrđeno je da projektirana baterija zadovoljava postavljene zahtjeve te je pripadni sustav hlađenja prisilnim strujanjem zraka dovoljan za odvodnju topline jer tijekom rada baterije ne dolazi do njenog pregrijavanja već ostaje u rasponu poželjnih temperatura rada.
Abstract (english)
Analysis was done based on hypothesized energy consumption of an electric vehicle with a desired range of 250 km and battery pack that fulfills all the requirements is designed. Important parameters when designing a battery pack are it's specific energy and specific power. To ensure adequate cooling of a battery pack and maintaining the desired battery temperature, first analytic thermal analysis was done and then the numerical analysis by using a MATLAB code was carried out in order to achieve more accurate results. CFD simulations of air flow through battery module based on CAD models were carried out to further understand the thermal behaviour of a battery pack. Optimising air duct geometry results in minimising pressure loss and improving the heat dissipation. Complete thermal analysis confirmed that the designed battery pack fulfills given requirements and that the battery cooling system is sufficient for taking over the heat from the battery because there is no overheating during the battery usage and optimal temperature range is maintained.
