Abstract

Disclosed is a quick charging method for charging a battery of electronic equipment by an adapter. The adapter is connected with the electronic equipment, and the electronic equipment comprises an application processor, a first charging circuit and a second charging circuit; the charging method comprises the following steps: the application processor detecting battery voltage; calculating required charging voltage according to the battery voltage and a preset condition; the adapter providing the charging voltage, and the application processor controlling the first charging circuit to quickly charge the battery; wherein in the quick charging process, the battery voltage is detected in real time, and the charging voltage is adjusted in real time to match the sum of the battery voltage and the charging loss voltage, so that the charging speed and the charging efficiency reach an optimal equilibrium.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a fast charging method and electronic equipment. Background technique [0002] The traditional and current mainstream fast charging technologies include Qualcomm's Quick Charge (fast charging technology); MTK's Pump Express Plus2.0 and OPPO's VOOC flash charging. The Charge ICs used in their Charge (charging) modules are all Switching Charger (Buck switch charging module) types. The battery is composed of a string of multi-parallel (1SnP) cells and a protective plate. [0003] Quick Charge: Its latest protocol is QC3.0, which has the highest degree of market promotion. It adopts high voltage and low current charging method to increase charging power, and uses D+D- to complete the protocol communication. However, due to high-voltage charging, the voltage difference between the input and output of the Charge module is large, and the efficiency will be lower than that of conventi...
