The distance (d) from the battery to the cooling plate is another key geometric element. The closer the battery is to the tube in the cooling plate, the greater the influence of the cooling tube on the cell temperature and the better the cooling effect. This also determines the length of the entire battery pack and the volume of the PCM.
The rated capacity (1C) of each battery is 3.2 Ah, and the rated discharge voltage is 3.56 V. It is assumed that the heat generation, density and heat capacity of the battery are homogeneous. The axial and radial thermal conductivity of the cylindrical lithium battery differs due to the different material composition in different directions.
This paper investigates the thermal performance of a liquid cooling lithium ion battery pack that uses cold plates through simulation. The three dimensional CFD model of the battery pack was established with the goal of reducing the maximum temperature and temperature difference of the battery pack.
Wang [ 23] designed a side liquid cooling system for cylindrical lithium batteries through numerical simulation and experiments. When the flow rate was small, increasing the flow rate of cooling water significantly reduced the maximum temperature in the battery module and improved the temperature uniformity.
However, multi-cooling plates can reduce the difference in the thermal performance among battery cells. In the studied operating conditions, the difference in the maximum temperature between the two end cells of the battery pack under the BDCP is reduced by an average of 20.8 % compared to the BCP.
With the application of the hybrid PCM/liquid-cooled plate battery cooling system, a safe temperature range of the battery pack is ensured even under multiple cycles of charging and discharging. The present work can facilitate future optimizations of the thermal management system of the large-capacity battery pack of electric vehicles. 1.
