摘要

锂离子电池低温性能衰退是制约寒区电动汽车产业化发展的瓶颈，低温加热是提升电池低温性能的有效措施。研究了基于短时大电流脉冲激励的锂离子电池低温自加热方法，分析了电池脉冲作用下的自生热特性，开展了加热过程中的电热协同仿真分析并进行了实验验证。实验结果表明，所提出的方法可以实现10.90 ℃/min的平均温升速率、升温20 ℃仅消耗4.35%电池标称容量。基于仿真分析，探究了电池模组加热过程中的单体温升一致性及其影响因素。结果表明，在低温加热时适度的入口风速对一致性影响并不显著，而单体内阻差异是导致温升不一致的主因。当内阻标准差为4.3 mΩ时，电池组单体温度极差高于6 ℃。

Abstract

收起

The performance degradation of lithium-ion batteries at low temperature is a main bottleneck that restricts the electric vehicle development in cold regions. Low temperature heating (LTH) is an effective solution. A study is conducted on LTH method based on short-term high-current pulse excitation, and the heating characteristics are analyzed. Electric and thermal co-simulations are conducted and verified by experiments. The results show that the presented method can achieve a heating rate of 10.90 °C/min and consumes 4.35% of nominal capacity for raising 20 °C. The temperature consistency and its influencing factors of single cells during the heating process of battery module is investigated by simulation analysis. The results indicate that the difference of resistance is the main cause of inconsistent temperature rise while the inlet wind speed only has a minor impact. When the standard deviation of internal resistance is 4.3 mΩ, the maximum temperature difference can reach over 6 ℃.
