Abstract

The invention provides a charging method, a charging device, and an electronic device, and is applied to charging control of a battery arranged in the electronic device. The method includes steps: obtaining a light intensity of an environment in which the electronic device is located; and stopping charging of the battery if it is determined that the obtained light intensity is lower than or equalto a set light intensity threshold and it is determined that the capacity stored by the battery is higher than or equal to a preset capacity threshold, wherein the preset capacity threshold is lower than a practical capacity value of the battery. In other words, whether the current time for charging of the battery of the electronic device is night is determined through the obtained light intensityof the environment in which the electronic device is located, and if yes, the charging of the battery is stopped when the capacity stored by the battery of the electronic device is lower than the practical capacity value of the battery so that the acceleration of attenuation of the cycle life of the battery due to long-time full-charging state of the battery of the electronic device after charging at night is avoided, and the service lifetime of the battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a charging method, charging equipment and electronic equipment. Background technique [0002] The batteries installed in electronic equipment are generally lithium-ion batteries. As the configuration of electronic equipment continues to improve, the demand for power and consumption continue to increase, the requirements for the life of lithium-ion batteries are also getting higher and higher. For example, dedicated to It is of great significance to increase the cycle life of lithium-ion batteries from 500 cycles to 800 cycles, 1000 cycles, and even 1500 cycles. [0003] The inventor found in the process of implementing the present invention that if the lithium-ion battery is often in a fully charged state during use (the electric quantity stored in the lithium-ion battery is equal to the actual capacity value of the battery), the cycle life of the lithium-ion battery will be acc...
