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.

Step S102 . Detect the power of the battery during the timing, and determine whether the power of the battery is less than the first preset power value.

In this embodiment, because after stopping charging the battery in the above steps, the battery is still in a state of power consumption in many cases, for example, the mobile terminal is in the power-on state during the charging process of the mobile terminal, and the battery stops after the battery of the mobile terminal is fully charged. When charging the battery, the mobile terminal will still consume power because it is turned on. Therefore, when the user turns on the mobile terminal, he will find that the battery is not fully charged. Therefore, in order to avoid this situation, in this step, during the timing The power of the battery is detected in real time and compared with the first power preset value, wherein, preferably, the first power preset value is 95% of the battery power when the battery is fully charged.

Step S103, when it is detected that the power of the battery is less than the first power preset value, the timer is reset and the battery is charged, and at the same time, the execution returns to step S101.

In this embodiment, when it is detected that the power of the battery is less than the first power preset value, it means that the power of the battery is consumed more at this time, and the battery needs to be charged again, so as to ensure that the battery is in the normal state when the user unplugs the charger. Full state.

Step S104. When it is detected that the electric quantity of the battery is not less than the first electric quantity preset value, when the timing time reaches the first time preset value, the timing is reset and the battery is charged, and at the same time, return to step S101.

In this embodiment, when the timing time reaches the first time preset value, although the power of the battery is still above the first power preset value, the battery may still consume part of the power and the battery is not fully charged, so when the timing reaches the first time preset value When the time is preset, the charging of the battery is restarted to avoid that the battery is not fully charged when the user unplugs the charger. Preferably, the first time preset is 4 hours.

When the judgment result is no, the first control unit 201 controls the timing of the first timing unit 203 to be reset and charge the battery when the timing time of the first timing unit 203 reaches the first time preset value.

The first power preset value is 95% of the battery power when the battery is fully charged, and the first time preset value is 4 hours.

Another embodiment of the present invention provides a battery charging control method, as shown in Figure 3, the control method includes the following steps:

Step S301. Stop charging the battery and start timing when the battery is fully charged.

Step S302. Detect the power of the battery during the timing process, and judge whether the power of the battery is less than the second preset value of power. When it is detected that the power of the battery is less than the second preset value of power, execute step S303. When the electric quantity is not less than the second electric quantity preset value, step S304 is executed.

Step S303. Reset the timer and charge the battery, and return to step S301;

Step S304. When the timing time reaches the second time preset value, judge whether the current power of the battery is less than the third power preset value. When it is detected that the battery power is less than the third power preset value, execute step S303. When the power of the battery is not less than the second power preset value, step S305 is executed.

Specifically, the second power preset value is 95% of the battery power when the battery is fully charged, and the third power preset value is 98% of the battery power when the battery is fully charged.

Step S305. When it is detected that the power of the battery is less than the third power preset value, reset the timer and charge the battery, and return to step S301; if no, reset the timer and charge the battery, and return to step D.

The preset value of the second time is 4 hours.

The second control unit 401 stops charging the battery when the battery is fully charged, and drives the second timing unit 403 to start timing;

The second detection unit 402 detects the electric quantity of the battery during the timing of the second timing unit 403, and the second control unit 401 judges whether the electric quantity of the battery is less than the second electric quantity preset value according to the electric quantity of the battery detected by the second detection unit 402, when When the judgment result is yes, the timing of the second timing unit 403 is controlled to be cleared and the battery is charged,

When the judgment result is no, the second control unit 401 judges whether the current power of the battery is less than the third power preset value when the timing time of the second timing unit 403 reaches the second time preset value, and when the judgment result is yes , control the timing of the second timing unit 403 to reset and charge the battery, and when the judgment result is negative, control the timing of the second timing unit 403 to reset and drive the second timing unit 403 to restart timing.

Wherein, the second power preset value is 95% of the battery power when the battery is fully charged, and the third power preset value is 98% of the battery power when the battery is fully charged.

Wherein, the preset value of the second time is 4 hours.

By setting the third power preset value, the power of the battery is further kept in a fully charged state, and the battery does not need to be in a charged state all the time, which satisfies the user's requirement for the battery to be in a fully charged state when the charger is removed.

A battery charging control method and device provided by the present invention, when the mobile terminal is connected to the charger for a long time, the number of repeated charging is reduced by setting the timing, and the service life of the battery is improved.
