摘要
为使电动汽车的锂电池组能够工作在规定的温度范围内,确保电池系统的使用安全。建立了电池组的液冷散热结构模型,并基于汽车在爬坡工况下的电池生热率模型,对电池组进行温度场分析计算。结果显示,该结构可以将电池的最大温升控制在10K以内;通过增大冷却液流量可以提高电池的散热能力。
In order to make sure the electric car lithium battery can work within the specified temperature range,and ensurethe safety of the battery system.A liquid cooling structure model of the battery is built.the battery pack temperature field isanalysis based on the battery heat generation rate model of climbing condition.The results show that the maximumtemperature rise can be controlled within10K,and the cooling capacity can be increased by increasing the coolant flow rate.
