摘　　要：在冬季低温条件下,锂离子电池的容量和功率特性严重衰减,需要预热以提高锂离子电池的输出功率和可用容量。根据热源的位置,目前锂离子电池在低温下预热的方法主要包括外部加热和内部加热。外部加热方式通常具有系统复杂度低、加热时间长、能量损失大、加热一致性差等缺点;虽然内部加热方法可以实现更短的加热时间、更低的能量损失和更好的温度一致性,但系统复杂度和安全风险更高。通过回顾锂离子电池预热方法的发展,总结目前预热过程中亟待解决的问题,并对未来的低温预热研究进行了展望。Under the condition of low temperature in winter,the capacity and power characteristics of lithium ion battery are seriously attenuated,so preheating is needed to improve the output power and available capacity of lithium ion battery.According to the location of heat source,the current methods of preheating lithium ion battery at low temperature mainly include external heating and internal heating.The external heating mode is usually characterized by low system complexity,long heating time,large energy loss and poor heating consistency.Although the internal heating method can achieve shorter heating time,lower energy loss,and better temperature consistency,the system complexity and security risks are higher.This paper reviews the development of preheating methods for lithium ion batteries,and summarizes the problems that need to be solved in the current preheating process,and prospects the future research on low temperature preheating.
