Generally divided into three stages: fast charging, supplementary charging and trickle charging: fast charging stage: charge the battery with a large current, Charger and quickly recover the battery energy, the charging rate can reach more than 1C. At this time, the charging voltage is low, Charger but the charging current will be limited within a certain value range.
Complementary charging phase: Compared with the fast charging phase, Charger the complementary charging phase can also be called the slow charging phase. When the fast charging phase is terminated, the battery is not fully sufficient, Charger and the charging process needs to be supplemented. The supplementary charging rate generally does not exceed 0.3C because the battery voltage increases after the fast charging stage, Charger and the charging voltage during the supplementary charging stage also increases and remains within a certain range.
trickle charging stage: In the latter part of the complementary charging stage,Charger when it is detected that the temperature rises above the limit value or the charging current drops to a certain value, charging is started with a smaller current until certain conditions are met.
