Abstract

The invention provides a battery charging management method and a circuit, which are used to solve a problem of a device battery being in a charging state for a long time. The battery charging management method is characterized in that a user can use a battery for supplying power or charge the battery; when the user chooses to use the battery for supplying the power, the lithium battery is disconnected, and is directly used for charging the device.

Description

technical field [0001] The invention relates to the field of battery technology, in particular to a battery charging management method and circuit. Background technique [0002] Lithium batteries are commonly used in mobile phones. The life of a lithium battery is calculated based on the number of complete charge and discharge cycles. The correct charging method is to try to avoid completely discharging and then recharging, and only need to work for a period of time to perform a complete discharge and charge. It is not advisable to charge the battery for a long time after it is fully charged, as charging for too long will be harmful to the battery. [0003] The current mobile phone is automatically charged after being plugged in. Even if the battery is fully charged, it no longer needs to be charged. In this case, it is very detrimental to the battery. But users can't constantly check the battery's charge status and unplug the charger when it's fully charged. Contents o...
