Abstract

Zadatak ovog rada bio je provesti numeričke simulacije hlađenja baterijskog modula pomoću rashladne tekućine u električnim vozilima. Simulacijski modeli izrađeni su u AVL Cruise M softveru pomoću kojeg simuliramo nekoliko domena proračuna. Najbitniji dio proračuna za ovaj rad bio je strujanje rashladne tekućine i izmjena topline između nje i baterijskog modula, no osim toplinskog proračuna i proračuna strujanja tekućine, proveden je i električni proračun pomoću kojeg dobivamo iznose generirane topline unutar baterijskih ćelija, te stanje napunjenosti baterije. Simulacijski modeli sadrže baterijski modul sa 12 „pouch“ baterijskih ćelija i predstavljaju ponašanje istih u stvarnom vremenu. Izrađena su tri modela sa različitim konfiguracijama rashladnog sustava, te jedan model koji uključuje čitavi rashladni krug sa konfiguracijom koja se pokazala optimalnom.¸

Abstract (english)

The task of this thesis was to perform numerical simulations of cooling a battery module using coolant in electric vehicles. Simulation models are made in AVL Cruise M software with which we simulate several domains of calculation. The most important part of the calculation for this thesis was the flow of coolant and heat exchange between it and the battery module, but in addition to thermal calculation and calculation of liquid flow, an electrical calculation was performed to obtain the amount of heat generated inside the battery cells. The simulation models contain a battery module with 12 pouch battery cells and represent their behavior in real time. Three models with different cooling system configurations were made, and also one model that includes the entire cooling circuit with a configuration that proved to be optimal.
