Embodiment Construction
[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0032] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.
[0033] An embodiment of the present invention provides a battery charging control method, such as figure 1 As shown, the control method includes the following steps:
[0034] Step S101. Stop charging the battery and start timing when the battery is fully charged.
[0035] In this embodiment, when the battery is fully charged, it stops charging the battery, preventing the battery from being charged multiple times after the battery is fully charged, and at the same time ...

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, various functions of mobile electronic equipment products are also increasing, and users spend more and more time using mobile equipment. Therefore, the battery life of mobile equipment is also raised. Very high requirements. For many mobile devices currently used by users, users need to charge them 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 is easy to have such a scene: the user has no chance to charge the mobile device until before going to bed to ensure sufficient power for the next day. Although various manufacturers have proposed products such as fast charging, more us...
