Mobile phone charger capable of carrying out automatic discharging/charging management and displaying battery capacity

Abstract

The invention discloses a mobile phone charger capable of carrying out automatic discharging / charging management and displaying battery capacity, which comprises a mode select switch, a constant-current discharge circuit, a automatic discharging / charging controlling management unit, a battery capacity computation and display circuit, a charging circuit and the like. The components are coordinated to complete the circulation of automatic discharging, charging and discharging of the mobile phone battery; and when the discharging times reaches the preset times, the mobile phone battery is not discharged any more, and the whole process is finished automatically. When new mobile phones are used or the mobile phones which are idle for a long time are reused, the battery is charged after running out in the first several times; while the charger automatically handles the process, and displays the storage capacity of the battery after charging so as to provide the battery capacity for users for reference, and promote mobile phone manufacturers to improve product quality; and when a suspected battery failure occurs, the charger is in a state of 'automatic discharging / charging mode', and displays the current battery capacity after charging, so a basis for judging the battery quality is provided, and the battery failure diagnosis is extremely convenient.

Description

technical field [0001] The invention relates to a mobile phone charger, specifically, a mobile phone charger with automatic reciprocating discharge, charging and battery capacity display. Background technique [0002] The existing problem of the mobile phone charger in the prior art mainly lies in: when purchasing a new mobile phone or a mobile phone battery that has been idle for a long time, when using it for the first time, the battery needs to be used up several times before charging. At present, the mobile phone can only be discharged naturally, and then charged with a charger after discharge. The time of discharge is unpredictable and changeable, and communication is sometimes interrupted because of this, and the battery capacity cannot be conveniently detected by the user. Bring great inconvenience to the user. [0003] In order to solve the above problems, people have been looking for new solutions. Contents of the invention [0004] The purpose of the present in...
