Problems solved by technology

[0003] The disadvantage of the existing solution is that it is difficult to solve the heating problem during high-voltage and high-current charging: as the input voltage of the charger increases and the output current increases, the charging efficiency decreases and the heat generated increases sharply
Heating causes the temperature of the handheld device to rise. The charging current must be reduced and the temperature must be controlled within a certain range. The cost is that the charging time becomes longer, which reduces the effect of fast charging, increases the charging waiting time of the user, and affects the user experience.

Abstract

The embodiment of the invention discloses a charge control method and a charge control device used for realizing parallel charging of a main charging IC (Integrated Circuit) and a plurality of fixed charging ICs by the charge control device, thus the charging efficiency is improved. The method of the embodiment of the invention comprises the following steps: detecting a battery, and acquiring an electric quantity value to be charged; calculating according to a fast charge protocol and the electric quantity value to be charged, and obtaining a charging current value; determining at least one fixed current IC according to the charging current value and the charging efficiency of a chip IC, and generating a control instruction, wherein the chip IC comprises the main charging IC and the fixed current IC; and connecting the main charging IC and at least one fixed current IC in parallel according to the control instruction.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a charging control method and a charging control device. Background technique [0002] The existing charging method is single or two charging integrated circuit ICs, and the structure is that a single IC directly steps down and charges, and two ICs are connected in parallel for charging. [0003] The disadvantage of the existing solution is that it is difficult to solve the heating problem during high-voltage and high-current charging: as the input voltage of the charger increases and the output current increases, the charging efficiency decreases and the heat generated increases sharply. Heating causes the temperature of the handheld device to rise. The charging current must be reduced and the temperature must be controlled within a certain range. The cost is that the charging time becomes longer, which reduces the effect of fast charging, increases the charging waiting time of...
