The invention discloses a quick charging method and electronic equipment for improving the charging speed. The method comprises the steps as follows: charging current is obtained; a battery is charged by the charging current, wherein the charging current is provided by a power adapter connected to the electronic equipment; the battery has limiting voltage; battery voltage when the battery is charged is monitored; whether the battery voltage is lower than the limiting voltage or not is determined on the basis of the battery voltage and the limiting voltage; and when the battery voltage is lower than the limiting voltage, the charging current is increased to the maximum current which can be provided by the power adapter, so that the charging speed for the battery is increased. The invention further discloses the corresponding electronic equipment.
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] In the prior art, when charging a lithium battery, the charging current is generally less than the maximum current that the lithium battery can support, and the charging current remains unchanged during the charging process. Although this can ensure the safety of the battery, the charging speed is relatively slow and the charging less efficient. Contents of the invention [0003] Embodiments of the present invention provide a fast charging method and electronic equipment for increasing the charging speed.
