| dc.description | The use of Electric Vehicle (EV) has become more important in the world nowadays due to environmental issues such as air pollution and global warming that are affected by the growing number of internal combustion engine vehicles. The battery plays an important role as a power source, which is providing power to the electric motor in order to operate the EV. However, when the battery operates at a high temperature, this could lead to uncontrollable overheating and the risk of meltdown or explosion. Meanwhile, high storage temperature could lead to lower recoverable energy and faster ageing. However, the batteries must be operated within their optimum range for safety factor. Good thermal management can enable a longer lifespan, lower costs and improve safety for EV batteries. In order to solve the thermal issue in battery a liquid cooling system can be used because it provides a battery capacity of 80% for more than nine years which is an increased lifespan of two years compared to air cooling. The main objective of this project is to determine the optimum parameter for enhanced rate of heat transfer for EV battery cooling purposes. In this study, Liquid Cold Plate (LCP) is introduced using an oblique fin and different types of liquid coolant. The liquid coolant used are water and ethylene glycol-based coolants, G12 and G13. The fins arrangements in the LCP would likewise impact the cooling efficiency of the EV battery. During testing, there are two key elements, which are two blocks of heater that work similar to battery pack as well as the LCP. The two blocks of heater are made of aluminium to ensure the uniformity of the heat flux and contain a 1.8 kW heater sheet. Three different rates of flow which are 0.3 gallon per minute (GPM), 0.5 GPM and 0.7 GPM could be utilized to maximize the productivity of fluid flowing and heat transfer with the gate door valve. Three liquid types are tested namely G13, G12 and distilled water at five different combinations. The LCP encompasses the inline configuration of the oblique fin which can enhance the heat transfer rate from the heater to the liquid coolant plate. Optimization is carried out using response surface method to find the optimum parameter for battery cooling. Among the three liquid coolant types which are G13, G12 and distilled water at five conditions, the results have shown that 25% G13 + 75% distilled water with 0.7 GPM reached the lowest surface temperature for the battery in the three different flow levels. The LCP is capable to sustain the ambient surface temperatures of the batteries just under the permissible 50°C operating temperature. This indicates that the developed LCP with oblique fin has a great potential to become an effective option for thermal control of EV batteries.,Master of Science | - |
