摘要
锂离子电池是最新一代的绿色高能充电电池,具有电压高,循环特性好和无记忆效应等优点。影响电池循环寿命的主要因素是电池的充电方式与充电效率,所以为锂离子电池提供高效安全的充电方案备受设计者的关注。根据锂离子电池的充放电特性,可以得出锂电池的充电方法有:)、恒压充电(CV)、恒流--CV)、脉冲充电等方式。本文主要介绍恒流--CV)的充电模式,既不会因为过充而损坏芯片,也不会出现充电不足的现象。即根据电池蓄电量的不同,采用不同的充电方式,根据规定大小的电流和电压进行充电。

ABSTRACT
lithium ion battery is a green high-energy rechargeable batteries for the latest generation, has advantages of high voltage, good circulation performance and no memory effect. The main factors that influence the cycle life of the battery is charging the battery and charging efficiency, charging scheme so to provide effective security for lithium ion battery has attracted the attention of designers. According to the charging and discharging characteristics of lithium ion battery, lithium battery charging method can be drawn: constant current charging, constant voltage charging (CC) (CV), constant current and constant voltage charging (CC-CV), pulse charging method. This paper mainly introduces the constant current and constant voltage charging (CC-CV) charging mode, not because the overcharge and damage the chip, also won't appear the phenomenon of lack of charging. According to the battery storage capacity is different, different charging, charging according to the provisions of the size of current and voltage.
