Charging method, charging device and electronic equipment

Abstract

The invention provides a charging method, a charging device and electronic equipment, and belongs to the field of electronic technologies. The charging method comprises the steps of acquiring an electric energy conversion efficiency function of each charging management unit of at least two charging management units; determining at least two charging current distribution schemes; calculating the total electric energy conversion efficiency of each charging current distribution scheme at least according to the electric energy conversion efficiency function of each charging management unit; determining a target charging current distribution scheme according to the total electric energy conversion efficiency of each charging current distribution scheme; and controlling each charging management unit to output charging current according to the target charging current distribution scheme. By adopting the charging method provided by the invention, each charging management unit is enabled to output charging current according to a distribution scheme with the highest total electric energy conversion efficiency when a plurality of charging management units output the charging current together, so that the electric energy conversion efficiency in the charging process is improved on the basis of ensuring the charging speed.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular to a charging method, device and electronic equipment. Background technique [0002] With the development of electronic technology, rechargeable electronic devices such as smart phones and tablet computers are more and more widely used in people's production and life, and how to charge electronic devices quickly and efficiently has become one of the important technical issues in this field. one. [0003] Generally, the electronic equipment is equipped with a charging management unit, and the charging current is output to the battery through the charging management unit. In order to increase the charging speed, it is often necessary to increase the charging current. Because the maximum charging current that a single charging management unit can output has an upper limit, which cannot meet the needs of increasing the charging speed, so two or more parallel charging mana...

Problems solved by technology

[0004] However, since the power conversion efficiency of each charging management unit is usually different, the above-mentioned equal distribution scheme often easily causes the problem of low total power conversion efficiency, and a charging method that can improve the total power conversion efficiency is urgently needed
