Abstract: To boost the performance of the air-cooling battery thermal management system, this study designed a novel vortex adjustment structure for the conventional air-cooling battery pack used in electric vehicles. T-shape vortex generating columns were proposed to be added between the battery cells in the battery pack. This structure could effectively change the aerodynamic patterns and thermodynamic properties of the battery pack, including turbulent eddy frequency, turbulent kinetic energy, and average Reynolds number, etc. The modified aerodynamic patterns and thermodynamic properties increased the heat transfer coefficient with little increase in energy consumption and almost no additional cost. Different designs were also evaluated and optimized under different working conditions. The results showed that the cooling performance of the Design 1 improved at both low and high air flow rates. At a small flow rate of 11.88 L/s, the Tmax and ΔT of Design 1 are 0.85 K and 0.49 K lower than the conventional design with an increase in pressure drop of 0.78 Pa. At a relative high flow rate of 47.52 L/s, the Tmax and ΔT of the Design 1 are also 0.46 K and 0.13 K lower than the conventional design with a slight increase in pressure drop of 17.88 Pa. These results demonstrated that the proposed vortex generating design can improve the cooling performance of the battery pack, which provides a guideline for the design and optimization of the high-performance air-cooling battery thermal management systems in electric vehicles.

Abstract: An air-cooling battery thermal management system is a reliable and cost-effective system to control the operating temperatures of the electric vehicle battery pack within an ideal range. Different from most designs of the rectangular battery pack in previous research, this one proposed a novel isosceles trapezoid layout to improve system heat dissipations. The simulation results showed that the trapezoid design delivered better cooling performances than the rectangular one with a maximum temperature reduction of 0.9 °C and maximum temperature difference reduction of 1.17 °C at the inlet air flow rate of 60 L/s. Moreover, the cooling performance was further boosted by an aluminum heat spreader. The boosted design delivers an average Max T (32.95 °C) and an average ΔT (3.10 °C) at five different flow rates, which are 8.8% and 66.1% lower the one without the spreader (35.85 °C and 5.15 °C). Compared with the rectangular design without the spreader, the average Max T and ΔT of the boosted trapezoid design are reduced by 10.4% and 91.9% in addition to a space-saving of about 5.26%.

Abstract: Air cooling is a highly cost-effective method for the battery thermal management systems due to its simple structure, high reliability and low maintenance cost. Different from other designs of only a single inlet/outlet structure in the literature, an air-cooling battery thermal management system with multiple inlets/outlets design was proposed in this paper. The effects of inlet/outlet positions and dimensions on the air-cooling battery thermal management system performance were thoroughly evaluated and compared. The optimal inlet/outlet position and dimension were identified based on the maximum battery temperature and the temperature uniformity in the air cooling field. The results showed that the symmetrical double inlets/outlets design (Design 4) delivered the top temperature uniformity with the lowest energy consumption. During 1C discharging at 2 m/s inlet airflow, the maximum temperature and temperature difference of the Design 4 were 1.01 K and 2.24 K lower than those of the basic Design 0 in addition to a pressure difference reduction of 7.85 Pa. Based on the optimal Design 4, 0.03 m outlet width could further reduce the maximum temperature and temperature difference by 0.47 K and 0.28 K than the worst 0.05 m design. Furthermore, 52 additional simulations under different operating conditions had proven that the superb cooling performance of the optimal design during mild discharging operations (0.5–1C).
