Performance Improvement of a Novel Trapezoid Air-Cooling Battery Thermal Management System for Electric Vehicles

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