| 摘要: |
| 锂离子电池作为电动汽车最广泛使用的动力源, 对工作温度高度敏感. 为保证其高性能和安全运行, 电池热管理系统必不可少. 本文综述了近年来锂离子电池热管理系统的研究进展. 首先讨论了由高低温环境和电池温度不均匀引起的临界热问题. 在此基础上, 对设计原则和现有的电池热管理系统进行了广泛的介绍和阐述. 然后进一步分析了用于未来电池热管理系统的热电器件和内部加热方法等新兴技术. 分析表明, 被动和主动冷却/加热方法的组合有望满足苛刻的热要求, 特别是在功率波动剧烈的动态条件下. 此外, 电池在变工况下所输出的电流、 电压等均不相同, 因此建议对电动汽车动力电池进行动态性能实时管理, 从而延长电池使用寿命. |

| Abstract: |
| As the most widely used power source for electric vehicles, lithium-ion batteries are highly sensitive to operating temperatures. To ensure its high performance and safe operation, a battery thermal management system is indispensable. In this paper, we review the research progress of thermal management systems for lithium-ion batteries in recent years. First, the critical thermal problem caused by the high and low temperature environment and the uneven battery temperature is discussed. On this basis, the design principles and existing battery thermal management systems are extensively introduced and elaborated. Emerging technologies such as thermoelectric devices and internal heating methods for future battery thermal management systems were further analyzed. The analysis shows that a combination of passive and active cooling/heating methods is expected to meet demanding thermal requirements9 especially under dynamic conditions with sharp power fluctuations. In addition, the current and voltage output of the battery under variable working conditions are not the same, so it is recommended to manage the dynamic performance of the electric vehicle power battery in real time to extend the battery life. |
