Problems solved by technology

[0007] Some terminal devices can only provide one way of power supply. During the charging process after the battery is over-discharged, because the battery is in the state of trickle charging, the voltage that provides the power for system operation will be lowered below the power-on threshold, causing these terminal devices to be in the charging process. It also doesn't boot properly and doesn't display the screen to meet the immediate needs of the user

Abstract

The invention provides a charging method and device and belongs to the communication technical field. With the charging method and device adopted, the input current of a battery can be cut off in the charging process of the over-discharge battery, and therefore, the problem that a terminal device cannot be started normally due the excessively low operating power supply voltage of a system can be solved. The method includes the following steps that: when current is inputted into a battery, whether the battery is in an over-discharge state is judged; when the battery is in the over-discharge state, the input current of the battery is cut off, and a system operates, a screen is displayed; and when a battery charging condition is satisfied, the input current of the battery is switched on. The charging method and device provided by embodiments of the invention are suitable for the charging process of the over-discharge battery of the terminal device.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of communication technology, in particular to a charging method and device. [0003] 【Background technique】 [0004] The development of existing communication technologies is uneven. At present, some terminal equipment does not have the path management function of the power management chip. The power management module used by these terminal equipment can only provide one way of power supply, that is, the power management module cannot control the system operation of the terminal equipment and the battery. Separate power supply, the system operation power of the terminal equipment and the battery charging share one road. [0005] In these terminal devices, if the terminal device is charged when the battery is over-discharged, the battery will be in a trickle charge state. During the charging process, the voltage of the power supply output by the power management The terminal device cannot be started normally d...
