Achieving the “Energy Roadmap 2050″ goal of the European Commission depends on energy storage technologies. These battery packs constitute the most critical component to distinguish electric vehicles, where these technologies are used extensively, from fossil fuel vehicles. The battery, which has short charging and discharging times, also has insufficient energy storage capacity. One of the parameters affecting charging and discharging times is the battery temperature. The battery temperature depends on thermal impacts from internal and external sources. In this study, climatic conditions with a thermal effect on the battery pack were examined and a new approach was presented concerning the passive liquid cooling system. In the experiments, the phase change material used for latent heat storage was integrated into the radiator. According to the results of the experiment, the temperature emitted by the periodic loading profile of the battery by 46.47%, enabling passive cooling in the system. Moreover, passive cooling occurred by 41.35% at the emitted temperature due to the aggressive high constant discharge current of the battery. Thus, the temperature emitted by the battery was absorbed and stable heat dissipation was observed through the integration of phase change material in the radiator. In addition, Reynolds number values were calculated for the pipeline that enables the heat transfer fluid temperature to be transmitted to the radiator and uncertainty analysis was performed. |
