What is fast charge?

Introduction :What is fast charge? It has three different implementation forms:
(1) The voltage remains unchanged, and the current is increased;
(2) The current remains unchanged, and the voltage is increased;

What is fast charge?

First of all, we must understand the charging and discharging principle of lithium-ion batteries. The battery has two poles: the positive electrode is a lithium compound, and the negative electrode is graphite. Both charging and discharging are the mutual conversion of electrical energy and chemical energy. During the movement of positive and negative electrodes, lithium ions are also changing into different compounds.

Fast charging is a relatively general concept, and it has three different implementation forms:

(1) The voltage remains unchanged, and the current is increased;

(2) The current remains unchanged, and the voltage is increased;

(3) Both voltage and current increase.

But to truly realize fast charging on mobile phones, it is not only sufficient to increase the voltage and current. Fast charging technology requires a set of customized circuits, batteries, interfaces, data cables and supporting fast charging adapters. At the same time, you also need to build a set of smart power management system so that the mobile phone can provide safe and intelligent according to different charging conditions. Charge protection.
