Abstract

The invention discloses a charging control circuit, a charging control method, a charging control device and a storage medium, and belongs to the technical field of circuits. The charging control circuit comprises a controller, a charging adjusting circuit and a charging management chip; the controller comprises a first input end, a first output end and a second input end; the charging management chip comprises a current setting end, a battery connecting end and a temperature detection end; the controller is electrically connected with the input end of the charging adjusting circuit through the first output end, the output end of the charging adjusting circuit is electrically connected with the current setting end of the charging management chip, and the controller is further electrically connected with the battery connecting end of the charging management chip through the first input end. And the battery connecting end of the charging management chip is also electrically connected with the positive electrode of the battery. The charging current can be adjusted in real time, the management capability of the charging current is improved in the charging process, the stability of the charging process is improved, the battery is protected, and the charging safety is improved.

Description

technical field [0001] The present application relates to the technical field of battery charging, and in particular to a charging control circuit, a charging control method, a device, and a storage medium. Background technique [0002] With the continuous development of science and technology, people use more and more types of terminals in real life. Among them, due to the characteristics of fast charging and small quality of lithium batteries, lithium batteries have been used as power supplies in various terminals. [0003] At present, most lithium batteries can be charged, and the charging process of lithium batteries is generally divided into three stages: trickle current, constant current, and constant voltage. Because the lithium battery is a temperature-sensitive device, during the charging process, due to the change of the battery temperature, the charging current required during the charging process is different, and during the charging process, if the battery tempe...
