Abstract

The invention relates to the field of battery charging control technology. The invention provides a battery charging control method and a device. The control method comprises the following steps: when a battery is fully charged, battery charging is stopped and timing is started; during timing, electric quantity of the battery is detected and whether battery capacity is less than a first electric quantity preset value is judged; if the battery capacity is less than the first electric quantity preset value, time is reset and the battery is charged; and if the battery capacity is not less than the first electric quantity preset value, time is reset and the battery is charged when the timekeeping time reaches a first time preset value, and timing is restarted when the battery is fully charged. By setting a timer, the number of repeated charge cycles is minimized, and service life of the battery is prolonged. Meanwhile, remaining capacity of the battery is detected at real time. Thus, the case that the battery is not fully charged because a charging protection circuit actively shuts the charging action is avoided, and it is ensured that the battery capacity of the battery is in a fully-charged state when a user pulls out a charger.

Description

Technical field [0001] The invention relates to the technical field of battery charging control, in particular to a battery charging control method and device. Background technique [0002] At present, with the widespread application of mobile electronic equipment products, there are more and more various functions of mobile electronic equipment products, and users use mobile devices for longer and longer. Therefore, the battery life of mobile devices is also proposed. Very high requirements. For many mobile devices currently used by users, users need to charge once a day. In many cases, such as working overtime, uninterrupted social application message push, film and television game applications for entertainment and travel, etc. It’s easy to happen that users don’t have the opportunity to charge their mobile devices until they go to bed to ensure enough power the next day. Although manufacturers have proposed products such as fast charging, more users It is often chosen to con...
