Learn MoreDiscussion: The proposed liquid cooling structure design can effectively manage and disperse the heat generated by the battery. This method provides a new idea for the optimization of the energy efficiency of the hybrid power system. This paper provides a new way for the efficient thermal management of the automotive power battery.
The battery liquid cooling heat dissipation structure uses liquid, which carries away the heat generated by the battery through circulating flow, thereby achieving heat dissipation effect (Yi et al., 2022).
For three types of liquid cooling systems with different structures, the battery's heat is absorbed by the coolant, leading to a continuous increase in the coolant temperature. Consequently, it is observed that the overall temperature of the battery pack increases in the direction of the coolant flow.
The maximum difference in Tmax between different batteries is less than 1°C, and the maximum difference in Tmin is less than 1.5°C. Therefore, the liquid cooling system's overall battery heat dissipation efficiency has somewhat increased. Fig 21. Initial structure and optimized structure Battery Tmax and Tmin.
2. Mathematic model 2.1. Control equation The heat transfer between the battery and the liquid cooled plate mainly relies on thermal conduction. Heat is transferred from the battery to the liquid cooling plate through the thermal conductivity of solid materials and then carried away by the coolant on the liquid cooling plate.
Liquid cooling systems typically use a liquid-cooled plate (LCP) in direct contact with the battery, which poses a risk of battery short-circuit by coolant leakage (Sutheesh et al., 2024).
