锂离子动力电池维护方式的实验研究

Research of Lithium Ion Power Battery Maintenance Mode

锂离子电池在生产及使用过程中经常面临存储问题,由于电池存在自放电导致存储过程中电池容量会有损失,因此,存储过程中需要采取恰当的维护方式,来保证电池的容量和性能。本文以方形锂离子动力电池为研究对象,研究了存储过程中维护频率对电池存储性能的影响。实验结果发现,尽管电池存储过程中需要定期维护,但是维护的时间间隔不当,对电池的性能保持也会有负面影响。

Lithium-ion batteries always faced with the storage problem when in production and in use process, because the battery has self-discharge, in the process of storage the battery capacity will have a loss, so we need to take appropriate way of maintenance to ensure that the capacity and performance of the battery. This paper use Square lithium ion power battery as the research object, researched the the maintenance frequency effect oll the battery performance. The experimental results show that although in the storage process, battery needs regular maintenance, but improper maintenance interval will also have a negative impact on battery performance.
