AB - Addressing the issues of temperature rise and inconsistent temperature uniformity in traditional staggered air-cooled battery thermal management systems, a novel cooling strategy based on air distribution pipes is proposed. By utilizing these pipes, cooling air is better distributed throughout the battery module, thereby compensating for the shortcomings of traditional structures in terms of cooling air distribution. Meanwhile, by taking advantage of the staggered arrangement, the problems of additional volume and complex piping that are commonly caused by the use of air distribution pipes are avoided, thus effectively making up for the shortcomings of the two methods. The results demonstrate that this design offers significant advantages over traditional structures. Based on this foundation, an optimization analysis has been conducted on the structural parameters of the air distribution device and those of the battery module. The findings reveal that when the module’s air outlet is positioned directly above, with an outlet radius of 6.5 mm, a battery spacing of 2 mm, an air distribution pipe outlet size of 5 ⋅ 10 mm2, and an angle between adjacent outlets of the air pipe of 40°, the battery thermal management system exhibits optimal temperature performance. Specifically, under the optimal configuration of structural parameters, when the charge/discharge rate reaches 2C, the maximum temperature of the battery module is 37.81°C the maximum temperature is reduced by 2.47°C compared to the traditional structure, while the temperature difference is decreased by 74.5%
