摘　　要：锂离子电池凭借其性能优点在各方面都得到了大量应用,但其在应用过程中的发热是一个必须注意的问题,它不仅影响锂离子电池的性能,也产生安全问题。基于此,用有限元软件ANSYS对水下航行器用锂离子电池组进行了温度场分析,并讨论了不同放电时间和边界条件对软件分析出的电池组温度场的影响。结果表明:放电时间和边界条件对软件分析出的电池组温度场有着明显的影响。Li-ion batteries are widely used in various fields because of its performance advantages,but its exothermicity is a problem that must be cared.It not only can influence the performance of Li-ion batteries,but also can bring safety problems.So,the temperature field of Li-ion batteries was analyzed in this paper using ANSYS,and the factor affecting temperature field of Li-ion batteries including discharge time was discussed.The result indicates that the discharge time and boundary condition influences the temperature of batteries obviously.
