锂离子电池保护元件自控制保险丝分析

Analysis of Self Control Fuse for Protection Element of Lithium-ion Battery

随着锂离子电池在便携式电子设备与电动汽车领域应用越来越多,其安全性也引起人们特别重视。本文从锂电保护的必要性出发,阐述了现有各大锂电保护方案的缺点以及自控制保险丝在锂电保护方面的优越性。最后已日本某公司生产的SCP为例介绍了自控制保险丝的工作原理与结构特征。

With more and more applications of lithium-ion batteries in portable electronic devices and electric vehicles,the safety of lithium-ion batteries has attracted special attention.Starting from the necessity of lithium-ion protection,this paper expounds the shortcomings of existing lithium-ion protection schemes and the advantages of self-control fuses in lithium-ion protection.At last,the working principle and structural characteristics of the selfcontrol fuse are introduced by taking the SCP produced by Dirui Co.of Japan as an example.
