The invention provides an electronic device and a charging method thereof. The electronic device comprises a battery module, a power supply, a power supply controller and a processor. The power supply controller obtains the initial electric quantity of the battery module and the current time when the power supply is connected with the external power supply. The processor is used for setting a predetermined target electric quantity and a charging completion time, obtaining a charging electric quantity according to the predetermined target electric quantity and the initial electric quantity, obtaining a charging time according to the charging completion time and the current time, calculating an electric quantity difference according to the charging electric quantity and the charging time, converting the electric quantity difference into charging power according to a power supply conversion relational expression, and transmitting the charging power to the power supply controller, so that the power supply controller converts the supply power provided by the power supply into corresponding charging voltage or charging current according to the charging power to charge the battery module, and the battery module is charged to a preset target electric quantity at the end point of the charging time.
Description
technical field [0001] The present application relates to an electronic device using dynamic charging power and a charging method thereof. Background technique [0002] Generally, a portable electronic device has a built-in rechargeable battery to provide power. When the user does not use the electronic device or the power is insufficient for future use for a period of time, the electronic device will be connected to a power source for charging. However, during the charging process, since the electronic device is connected to the power source for a long time, if the battery is maintained at a high or full capacity state for a long time, such as 80% to 100% power, it will affect the service life of the battery, resulting in The life of the battery is reduced, and even the battery is damaged. Contents of the invention [0003] In view of this, the present application provides an electronic device including a battery module, a power supply, a power controller and a processor...
