detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings.

The charging method can be applied to a charging device, and the charging device can be built in or externally connected to the terminal. Here, the terminal can be a smart phone, a tablet computer, a notebook computer or the like. The terminal has a power source capable of supplying power to the terminal itself, and also outputting power to the external device, so that the external device performs charging.

In practical applications, when the terminal charges the external device, the terminal internally sets a detection period. When the detection period arrives, the terminal wakes up itself to detect the current remaining power of the power source. Then, in the embodiment of the present invention, if the current detection period timing duration is the first preset duration, the foregoing method may be:

FIG. 1 is a schematic diagram of a first flow chart of a charging method according to an embodiment of the present invention. Referring to FIG. 1 , the method includes:

S101: When the first preset duration arrives, detecting whether the terminal is in a dormant state;

Here, the terminal starts a preset timer after the external device accesses the charging, and when the first preset duration of the timer is reached, the terminal detects whether it is in the sleep state. In the embodiment of the present invention, when the terminal is in the sleep state, the terminal can continue to output power to the external device. The first preset duration may be 3s, 5s, 10s, etc., and is not specifically limited in the embodiment of the present invention.

S102: If the terminal is in a sleep state, wake up the terminal, and detect the current remaining power of the power source;

Here, the terminal wakes itself up when detecting that it is in the sleep state, and detects the current remaining power of its own power source. In practical applications, in general, the power of the power supply is defined by a percentage. The detection of the current remaining power of the power supply can be obtained by detecting the output voltage of the power supply, or by detecting the power of the power supply. Of course, other detection methods can also be used. The embodiment of the present invention is not specifically limited.

S103: When the remaining power is greater than the first preset threshold, determining a second preset duration according to the remaining power according to a preset rule;

The first preset threshold is a cutoff power value of the power supply of the terminal to the external device, such as 25%, 20%, 15%, etc., and the cutoff power value is set to prevent the power source from being over-discharged, for different characteristics. For the power supply of the terminal, the cutoff power can be set to a different value, and is set according to the technical features corresponding to the specific power supply model, which is not specifically limited in the embodiment of the present invention.

Here, the terminal calculates the second preset duration when determining that the current remaining power is greater than the first preset threshold. The second preset duration is the time interval from the next wake-up detection. The detection period may be an equal-length period, that is, the first preset duration is equal to the second preset duration, or may be an unequal-length period, that is, the first preset duration is not equal to the second preset duration. The embodiment of the invention is not specifically limited.

In a specific implementation process, since frequently awakening the terminal in the sleep causes the standby current to increase and the power consumption is increased, in order to reduce the power consumption and reduce the frequent wake-up of the terminal, the S103 may include: acquiring the total power of the power source, and calculating the total The ratio of the power to the power consumption of the external device; calculating the percentage difference between the remaining power and the first preset threshold; calculating the product of the difference percentage and the ratio, and taking the product as the second preset duration.

Specifically, the terminal according to its own configuration information, the total available power supply itself _total C, and then, calculates the total amount _{of total} C and an external device _outside the charging current I, i.e., the ratio of the input current value of the external device, then Since the power of the power source is expressed as a percentage, the percentage difference between the remaining power P _now and the first preset threshold P _stop is calculated, and the difference percentage is multiplied by the ratio, and the product is taken as the second. The preset duration. In this way, iteratively obtains the preset duration, that is, the more the remaining power, the longer the preset duration, and the lower the wake-up frequency.

For example, the second preset time length t described above can be obtained by the following formula (1).

Wherein, t is the duration of a second predetermined, C _total is the total power supply, the I _outside the charging current of the external device, P _now the current remaining power, P _stop first predetermined threshold, i.e., an external device The value of the charge cutoff.

S104: The control terminal enters the sleep state again, and starts timing with the second preset duration;

Here, after determining the second preset duration, the terminal controls itself to enter the sleep state again, and starts timing with the second preset duration, waiting for the next wakeup when the second preset duration arrives.

S105: When the second preset duration is reached, return to the step of detecting whether the terminal is in a sleep state in S101.

Here, when the second preset duration arrives, the terminal returns to S101 to detect whether the terminal is in the sleep state again. If yes, S102 to S105 are executed again, and the loop is continued until the remaining power is less than or equal to the first preset threshold, and S106 is performed. .

S106: Stop charging the external device when the remaining power is less than or equal to the first preset threshold.

Here, after S102, when determining that the current remaining power is less than or equal to the first preset threshold, the terminal indicates that the current remaining power of the terminal power is insufficient to support charging the external device, so, at this time, the terminal stops. Charge external devices.

The charging method provided by the embodiment of the present invention will be described below by way of specific examples.

2 is a schematic diagram of a second process of a charging method according to an embodiment of the present invention. Referring to FIG. 2, the method includes:

S201: When the first preset duration arrives, the terminal detects whether the user is in a dormant state;

S202: If the terminal is in a dormant state, the terminal wakes itself up and detects the current remaining power of the power source;

S203: The terminal determines whether the remaining power is less than or equal to the first preset threshold; if the remaining power is greater than the first preset threshold, the process goes to S204; if the remaining power is less than or equal to the first preset threshold, the jump Go to S209;

S204: The terminal acquires the total power of the power source, and calculates a ratio of the total power to the charging current of the external device.

S205: The terminal calculates a percentage difference between the remaining power and the first preset threshold.

S206: The terminal calculates a product of the difference percentage and the ratio, and uses the product as the second preset duration;

S207: The terminal control terminal enters the sleep state again, and starts timing with the second preset duration;

S208: When the second preset duration is reached, return to S201;

S209: Stop charging the external device.

In the embodiment of the present invention, when the first preset duration arrives, the terminal is detected to be in a dormant state. If the terminal is in the dormant state, the terminal wakes up the terminal, detects the current remaining power of the terminal, and wakes up the terminal and updates the sleep state. The current remaining power of the power source avoids that when the terminal is in the sleep state and the remaining power is less than or equal to the first preset threshold, the external device is not stopped in time to prevent the power from being over-discharged; then, when the remaining power is greater than the first When a preset threshold is used, according to a preset rule, the second preset duration is determined according to the remaining power, the control terminal enters the sleep state again, and the second preset duration is started, and when the second preset duration arrives, the detection terminal is returned. If the terminal is in the dormant state, it can be seen that when the terminal is in the dormant state, the remaining power of the power source can be updated, a reasonable wake-up time is realized, and the energy saving of the terminal is ensured. The solution of the embodiment of the present invention can reduce the terminal when connecting the external device. The failure rate increases the terminal life.

Based on the foregoing embodiment, in the actual application, if the terminal is unable to externally charge when the power of the terminal is lower than a certain percentage of power, that is, the first preset threshold, the first preset threshold is divided. If the corresponding voltage is too low, the power will be pulled down at the moment of large load access. The output voltage causes the terminal hardware to shut down. If the voltage corresponding to the first preset threshold is too high, the terminal will turn off the external discharge function too early, so that the terminal clearly has a lot of power remaining, but it cannot be externally The charging of the device occurs. Then, in order to solve this problem, FIG. 3 is a schematic diagram of a third process of the charging method in the embodiment of the present invention. Referring to FIG. 3, after the foregoing S102, the method further includes:

S301: When the remaining power is less than or equal to the second preset threshold, detecting an output voltage value of the power source;

Here, after detecting the current remaining power of the power source, the terminal determines whether the remaining power is less than or equal to a second preset threshold, where the second preset threshold is greater than the first preset threshold, and The difference between the first preset threshold is less than the preset value, that is, the first preset threshold is near the first preset threshold, for example, the first preset threshold is 25%, and the second pre- The threshold value may be set to 30%; the first preset threshold is 20%, and the second preset threshold may be 23%. Of course, there may be other cases, which are not specifically limited in the embodiment of the present invention. . When the remaining power is less than or equal to the second preset threshold, the terminal detects the output voltage value of the power source.

S302: Determine a corresponding current limiting current according to a mapping relationship between the output voltage value and the charging current;

S303: When the external device is connected, the external device is charged with the current limiting current.

Here, S302 to S303 may be that, since the output voltage value is different under the condition that the power source is different in the remaining power, then, in order to prevent the output voltage from being pulled low at the moment when the external device is accessed, when the remaining power reaches the second preset threshold After that, according to the mapping relationship between the output voltage value and the charging current, the corresponding current limiting current is determined, so that the output current of the terminal is configured as a current limiting current. Thus, when the external device accesses the terminal, the terminal can use the current limiting current pair. The external device is charging.

In practical applications, the mapping relationship between the output voltage value and the charging current may be one-to-one mapping between the output voltage value and the charging current value, or may be a mapping of the output voltage value and the charging current step, that is, an output current value mapping. The range of the value of a charging current, of course, there may be other cases, the strength of the present invention is not specifically limited.

In an embodiment, after the current limiting process is performed when the external device is accessed, the terminal may further determine whether to resume full-load charging according to the remaining power of the terminal. Then, after S303, the method may further include: detecting a current remaining power; determining whether the remaining power is less than a third preset threshold; and if the remaining power is greater than or equal to a third preset threshold, the rated output current is external device Charge it.

Here, after the terminal accesses the external device for a period of time, such as 3s and 5s, the terminal detects the current remaining power again, and determines whether the remaining power is less than the third preset threshold. Here, the third preset threshold may be If the preset threshold is consistent, it may be greater than the preset first threshold. If the remaining power is greater than or equal to the third preset threshold, it indicates that the remaining power of the terminal is sufficient to fully charge the external device. The terminal charges the external device with the rated output current.

In a specific implementation process, after S303, the terminal may further perform S103 to S106.

In the embodiment of the present invention, the second preset threshold is set in the vicinity of the first preset threshold, that is, the external charging cutoff threshold, and when the remaining power is less than or equal to the second preset threshold, the power is detected. Output voltage value, and then, according to the mapping relationship between the output voltage value and the charging current, determine the corresponding current limiting current, and when the external device is connected, the external device is charged with the current limiting current, thus avoiding the large load When an external device is connected, the output voltage of the terminal power supply is instantaneously pulled down, resulting in a failure of the terminal screen or hardware shutdown. Further, after the charging of the external device is stabilized, it is determined whether the remaining power is greater than a third preset threshold, that is, whether the remaining power of the terminal can be fully charged to the external device, and if so, the rated output current of the power source Charge the external device to improve the efficiency of the terminal's external charging.
