This demo shows an Electric Vehicle (EV) battery cooling system. The battery packs are located on top of a cold plate which consists of cooling channels to direct the cooling liquid flow below the battery packs. The heat absorbed by the cooling liquid is transported to the Heating-Cooling Unit.
Hence, as mentioned in section 3.9, a DOE for different ambient temperatures and initial Battery temperatures and this was done for different configurations of the cooling system. The configurations of cooling system were changed by using the control valves to direct the flow to either of the heat exchangers (Chiller or Radiator) or both.
The battery packs are located on top of a cold plate which consists of cooling channels to direct the cooling liquid flow below the battery packs. The heat absorbed by the cooling liquid is transported to the Heating-Cooling Unit. The Heating-Cooling Unit consists of three branches to switch operating modes to cool and heat the battery.
Hence the main systems that need cooling are the Battery system and the Electrical components system. The emphasis of the thesis work mainly focuses on Cooling System for the High Voltage Battery.
In order to carry out the thesis work, a 1D CFD modelling tool was used to model the cooling system for Battery. The software used to accomplish this thesis work was GT-SUITE, a commercial software very widely used in automotive industry for vehicle development.
As seen in Figure 3-1, two of the cooling systems as a part of the complete vehicle cooling systems category are the Battery cooling system and the Electrical components cooling system.
