Problems solved by technology
[0004] For portable terminals such as mobile phones, MP4 players, and tablet computers, battery life is usually achieved through the energy stored in the terminal battery. The above-mentioned terminals have relatively high requirements for battery life. This charging method directly uses the relationship between the state of charge (SOC) of the terminal battery in the prior art and the saturation value of the float charge to control charging. When the saturation value is reached, the charging power supply does not charge the battery of the terminal, but the battery power is not fully charged, resulting in low battery life of the terminal.

The embodiment of the present invention provides a charging method and device, relates to the technical field of batteries, and can ensure that when the battery electric quantity of a terminal connected with a charging power supply is greater than the floating charge saturation value, a battery management system can still control the conduction of the charging circuit so as to ensure that the battery of the terminal is sufficiently charged when the battery of the terminal is disconnected from the charging power supply without affecting the service life of the battery, thereby improving the endurance of the terminal. The method comprises the following steps: firstly, obtaining the initial remaining battery electric quantity of the terminal; Then, comparing the initial battery remaining electric quantity with a first threshold value; thu, when the initial battery remaining electric quantity is smaller than the first threshold value, the charging circuit is controlled to be turned on so that the charging power supply charges the terminal battery; wherein the first threshold is greater than a floating charge saturation threshold. The technical proposal provided by the invention is suitable for the battery charging process.
Description
【Technical field】 [0001] The invention relates to the technical field of batteries, in particular to a charging method and device. 【Background technique】 [0002] In the process of charging the battery, when the battery is fully charged, if the battery is still connected to the power supply, the battery will keep trickle charging, and the battery will enter the floating charge state, which will reduce the service life of the battery. In order to avoid the occurrence of floating charging and improve the service life of the battery, in the prior art, when the personal computer is connected to the charging power source, when the battery management system of the personal computer detects that the current battery power value is lower than the battery floating charge saturation value, The battery management system starts the charging process to charge the battery, and the battery management system controls to stop charging after charging to full charge. [0003] In the course of ...
