Abstract

With the growing global energy and environmental problems, electric vehicles that are both environmentally friendly and cost effective have seen rapid growth. An electrified vehicle’s effective thermal management must include all of the vehicle’s systems. However, optimizing the thermal behavior of each component is insufficient. A lithium-ion battery’s operating temperature has a significant impact on its performance. When working at low temperatures, the internal resistance of lithium-ion batteries increases, the available energy and power of the system decreases, and lithium precipitation caused by low-temperature charging may cause safety issues; high-temperature operation and temperature inconsistency between battery cells will cause accelerated ageing of the battery, which may result in safety issues such as thermal runaway. As a result, to keep the temperature of the battery module under control, electric cars require a strong thermal management system. Thermal management must be handled at the system level to maximize the vehicle’s overall performance. The integrated thermal management system for electric vehicles has the potential to significantly increase vehicle energy efficiency. However, it’s construction is complicated due to the thermal requirements of the battery and cabin. In this research, a multi-channel liquid cooling system with a serpentine wavy structure was used to conduct an experimental thermal investigation of a lithium-ion battery pack. The suggested cooling system’s capabilities was examined under various charge/discharge scenarios using varied coolant flow rates and pumping power. The findings revealed that the suggested cooling system was successful across a variety of charging and discharging settings, with most of the tested scenarios achieving a maximum temperature difference.
