摘要:
锂电池适宜的工作环境温度最高为50 ℃左右,有效的控制电池组温度是新能源汽车行业最重要的工作之一。采用Fluent流体力学计算方法,建立液冷散热锂电池组三维仿真模型。在1 C、3 C放电倍率下,对不同流道结构的电池组进行流-固耦合仿真,结果表明:U型流道电池最高温度比串型和双串型分别降低了2.79、0.69 K;对U流道结构,截面形状长宽比为9∶4、4∶1和1∶1的电池进行散热仿真,截面形状长宽比为1∶1比9∶4、4∶1分别降低了4.09、2.89 K。研究结果验证了流道结构会影响电池组冷却性能,为锂电池组流道结构设计提供了依据。
Abstract:
The most suitable working environment temperature of lithium battery is up to about 50 ℃. Effective control of battery pack temperature is one of the principal task in the new energy vehicle industry. In this paper, the fluent fluid mechanics calculation method was used to establish a three-dimensional simulation model of liquid-cooled lithium battery pack. At 1C and 3C discharge rates, fluid-solid coupling simulation was carried out for battery packs with different flow channel structures. The results showed that the maximum temperature of U-channel batteries is 2.79 and 0.69 K lower than that of string diffusion and double string diffusion batteries, respectively. For the U-channel structure, the heat dissipation simulation was carried out for the battery with the section shape aspect ratios of 9∶4, 4∶1 and 1∶1, and the section shape aspect ratio of 1∶1 was 4.09 and 2.89 K lower than that of 9∶4 and 4∶1, respectively. The results verify that the flow channel structure can affect the cooling performance of battery pack, which provides a basis for the design of the flow channel structure of lithium battery pack.
