摘要:

目前,针对动力电池的梯次利用存在着争议,一种观点认为退役电池不具备梯次利用的价值,应直接回收;另一种观点则认为退役电池大多数可梯次利用。本文从能否梯次利用的判断准则、梯次利用时的关键问题及应该做的工作3个方面阐述了笔者的看法,其中能否梯次利用应从安全性和经济性来判断,要考虑的关键问题包含电池状态的快速诊断、电池重组和应用场景的选择,当下应该做的工作包括突破退役动力电池安全隐患诊断等关键技术、开展小规模示范应用和完善数据体系。

关键词: 动力电池, 梯次利用, 判断准则, 状态诊断

Abstract:

Currently, there is a controversy about the reuse of power batteries. One view is that retired batteries do not have any secondary use value and should be recycled. Another view is that most retired batteries can be used. This study explains the author's views on the judgment standard of whether power batteries can be secondary-used, the key problems in the secondary use batteries, and the future work that should be undertaken. Whether power batteries can be secondary-used should be judged in terms of safety and economy. The key issues to be considered include the rapid diagnosis of the battery state, battery reorganization, and the selection of application scenarios. Currently, the development of breakthrough technologies to evaluate the safety risk of retired power batteries, small-scale demonstration applications, and improvement in data systems is required.

Key words: power batteries, secondary-used, judgment standard, state diagnosis
