At low temperatures, the charge/discharge capacity of lithium-ion batteries (LIB) applied in electric vehicles (EVs) will show a significant degradation. Additionally, LIB are difficult to charge, and their negative surface can easily accumulate and form lithium metal.
The temperature difference is less than 2 °C, which fully indicates that the numerical simulation of the battery temperature field thermal model used in this paper can well reflect the actual heat generation of lithium-ion power batteries. Figure 5. Thermal model verification of single cells.
Based on this, a cooling plate with six channels was applied to both the top and bottom parts, and the top and bottom cooling showed sufficient cooling performance in maintaining the average temperature of the battery module below 45 °C. 1. Introduction
The lithium-ion battery module and the air environment are convection heat transfer, the convection heat transfer coefficient is set to 5 W (m 2 *K), and the ambient temperature is 298.15 K. Coupled algorithm was adopted for the coupling method of pressure and velocity.
This study’s outcomes offer valuable insights for the development of liquid-cooled battery thermal management systems that are energy-efficient and offer superior heat transfer capabilities.
In addition, the average temperature difference between the upper and bottom regions of the battery increased by 0.27 °C, from 13.7 °C to 14.0 °C, while the width of the cooling plate channel increased from 15.3 to 23.3 mm.
