Lithium-ion battery charger fast charging principle
Generally speaking, fast charging uses DC charging, and the
simplistic understanding of fast charging mode is to quickly charge
the battery with a large current in less than 1 hour, and secondly,
regarding the inside of the battery, the lithium ion should be
accelerated to the negative electrode during fast charging. First
of all, the charging is carried out with a wide charging pulse, the
terminal voltage of the battery rises, when the time set by the
charging time is reached, the charger pauses charging, and the
charger continues to charge when the charging interval reaches
another point.
The charger part and the power management part, the chip of the
power management part is placed in the mobile intelligent terminal,
and some are directly integrated in the mobile phone package, and
the power management chip manages and monitors the entire charging
process of the lithium-ion battery, including a complex processing
algorithm.
In the pre-charging stage, constant current charging stage,
constant voltage charging stage, and trickle charging stage, the
charging management chip sends instructions to the charger
according to the electrical characteristics of each stage of the
lithium-ion battery charging process, notifying the charger to
change the charging voltage and current, and the charger receives
the demand from the charging management system, adjusts the output
parameters of the charger in real time, and realizes fast charging
with the charging management system.
Fast charging refers to the charging method with a charging current
greater than 0.1C, which has little impact on the life and
stability of a single lithium-ion battery, but in the case of
battery packs, fast charging is an act of exchanging time for
battery life.
