Please refer to FIG. 2 . FIG. 2 is another schematic flowchart of a charging control method provided by an embodiment of the present invention. The methods include:

Step S201, detecting the temperature of the battery during charging.

It can be understood that the charging process of lithium batteries is divided into four stages, namely the trickle charging stage (pre-charging), constant current charging stage, constant voltage charging stage and charging termination stage (saturation charging), usually by the mobile terminal The internal charging management chip adjusts the charging parameters for charging the battery according to the charging stage of the lithium battery. Among them, during the constant current charging stage, the lithium battery is in the state of maximum charging current, and the power consumption of the charging management chip is relatively large at this time, which will cause the internal temperature of the mobile terminal, especially the temperature of the lithium battery, to rise. Therefore, in order to improve mobile If the temperature of the terminal is too high, you can start to detect the temperature of the battery during the charging process after entering the constant current charging stage.

The temperature of the battery during charging can be detected within a preset time. The preset time can be detected by experimenting with temperature changes of the battery of the mobile terminal in various simulated scenarios, and then analyzed to obtain a reasonable preset time. For example, the preset time is 5 minutes, and the temperature of the battery during charging is detected every five minutes.

Step S202, when the temperature of the battery reaches a first preset temperature, detect the power range to which the current power of the battery belongs, wherein each power range corresponds to a charging strategy.

It can be understood that the first preset temperature can be used to test the influence of different battery temperatures of the mobile terminal on battery performance in various simulated scenarios through experiments, so as to analyze the temperature value that will obviously affect the battery performance as the first preset temperature. a preset temperature. For example, it is detected through experiments that lithium batteries can work in the temperature range of -10 to 55°C, but the more suitable temperature range for charging is 5 to 45°C, especially the temperature range of 10 to 35°C is better, and the temperature range of 5 to 55°C is better. The charging effect is very poor at a temperature range other than 45°C, for example, the first preset temperature is set to 40°C.

In some implementations, the power interval may include a first power interval, a second electric power interval, and a third electric power interval.

The step S202 can be realized through steps S2021 to S2023, specifically:

Step S2021, when it is detected that the current battery power is less than the first threshold, determine that the current battery power belongs to the first power range.

For example, the first threshold is 40% of the battery capacity. When it is detected that the current battery power is 20% of the battery capacity, the current battery power is less than a first threshold, and it is determined that the current battery power belongs to the first power range.

For example, the first power range corresponds to a first charging strategy, wherein the first charging strategy may be: maintain the current charging current of the battery, and when it is detected that the temperature of the battery rises to a second preset temperature, reduce the charging current of the battery, wherein the second preset temperature is greater than the first preset temperature.

Step S2022, when it is detected that the current battery power is greater than or equal to the first threshold and less than the second threshold, determine that the current battery power belongs to the second power range.

For example, the first threshold is 40% of the battery capacity, and the second threshold is 80% of the battery capacity. When it is detected that the current battery power is 50% of the battery capacity, the current battery power is greater than the first threshold and smaller than the second threshold, and it is determined that the current battery power belongs to the second power range.

For example, the second power range corresponds to a second charging strategy, wherein the second charging strategy may be: reduce the charging current of the battery, and when it is detected that the temperature of the battery drops to the third predetermined When setting the temperature, re-increase the charging current of the battery, wherein the third temperature is lower than the first preset temperature.

Step S2023, when it is detected that the current battery power is greater than or equal to the second threshold, determine that the current battery power belongs to the third power range.

For example, the second threshold is 80% of the battery capacity. When it is detected that the current battery power is 85% of the battery capacity, the current battery power is greater than the second threshold, and it is determined that the current battery power belongs to the third power range.

For example, the third power range corresponds to a third charging strategy, wherein the third charging strategy may be: reduce the charging current of the battery, and charge the battery with the reduced charging current before the battery is fully charged. Keep charging.

Step S203, adjusting the charging current of the battery according to the charging strategy corresponding to the power range to which the current power capacity of the battery belongs.

In some implementations, the charging current of the battery includes constant charging currents in multiple gears. The charging current of the battery can be adjusted according to the charging strategy corresponding to the preset electric quantity interval to which the current electric quantity of the battery belongs, and the constant current charging current of the gear matching the current electric quantity of the battery.

For example, the charging current of the battery includes 4.5A, 3A, 2A, 1A, 0.5A, and other constant-current charging currents.

In some implementation manners, the step S203 can be realized through steps S2031 to S2033, specifically:

Step S2031, when the current charge of the battery belongs to the first charge range, maintain the current charging current of the battery, and reduce the charge current of the battery when it is detected that the temperature of the battery has risen to a second preset temperature. The charging current of the battery, wherein the second preset temperature is greater than the first preset temperature.

It can be understood that, when the current power of the battery belongs to the first power range, for example, the current power of the battery is 12% of the battery capacity, and the power of the mobile terminal is relatively low at this time, in order to ensure Charge the battery of the mobile terminal in many places to maintain the normal operation of the mobile terminal, without regulating the charging current, and maintain the current high current of the battery for charging, so as to satisfy the user's need to charge the mobile terminal being charged as much as possible in a short time. into the demand for more power. However, when the temperature is too high, it is easy to affect the performance of the battery, and when it is detected that the temperature of the battery rises to the second preset temperature, the charging current of the battery is reduced, so that the battery of the mobile terminal passes through Slowly cool down after a period of time to prevent the temperature from being too high and affecting the charging efficiency of the battery. When the temperature of the battery is lower than the first preset temperature, it is adjusted to high current charging again.

Step S2032, when the current battery capacity belongs to the second power range, reduce the charging current of the battery, and increase the charging current again when it is detected that the temperature of the battery drops to the third preset temperature. increasing the charging current of the battery, wherein the third temperature is lower than the first preset temperature.

It can be understood that when the current power of the battery belongs to the second power interval, for example, the current power of the battery is 50% of the battery capacity, the power of the mobile terminal can maintain the operation of the mobile terminal for a long time, in order Reducing the temperature of the mobile terminal, especially the temperature of the battery, can reduce the thermal power consumption of the mobile terminal by reducing the charging current. For example, after an interval of 10 minutes, the temperature of the battery is detected again, and when the temperature value of the battery drops to the third preset temperature, the battery returns to a high current for charging. When the temperature value of the battery reaches the first preset temperature again, the charging current of the battery is reduced again. In the constant current charging stage, the temperature of the battery is continuously monitored within a preset time period, and the charging current of the battery is repeatedly adjusted correspondingly according to the detected temperature.

Step S2033, when the current battery capacity belongs to the third power range, reduce the charging current of the battery, and continue charging the battery with the reduced charging current before the battery is fully charged.

It can be understood that when the current power of the battery belongs to the third power range, for example, the current power of the battery is 90% of the battery capacity, and the power of the mobile terminal is almost full at this time, in order to reduce the temperature of the mobile terminal, especially is the temperature of the battery, and the thermal power consumption of the mobile terminal can be reduced by reducing the charging current. And when the temperature of the battery is lower than the third preset temperature, in order to avoid overcharging, the charging current is no longer increased, and the battery is continuously charged with the reduced charging current before the battery is fully charged, so The above-mentioned reduced charging current can be charged according to the standard charging current value of the constant voltage charging stage after entering the constant voltage charging stage, until entering the charging termination stage.

According to the above steps, during the charging process, the temperature of the battery and the power range to which the current power of the battery belongs are continuously monitored within a preset time period, and corresponding adjustments are repeated based on the detected temperature and the power range to which the current power of the battery belongs battery charging current.

In order to understand the embodiment of the present invention more clearly, please refer to FIG. 3 . FIG. 3 is a graph of temperature, current and power in a charging control method provided by the embodiment of the present invention.

At the beginning of charging, it enters the pre-charging stage first, and pre-charges with a charging current of 0.5A; after the pre-charging is completed, it enters the constant-current charging stage, and charges with a maximum charging current of 4.5A.

For example, the first preset threshold is 40°C, and the second preset threshold is 50°C. When the temperature of the battery reaches the first preset temperature of 40°C, it is detected that the current charge of the battery is 12% of the battery capacity, and the electric charge interval it belongs to is the first electric charge interval, then the current charging current of the battery is maintained at 4.5A . When it is detected that the temperature of the battery rises to the second preset temperature of 50°C, the current charging current of 4.5A is reduced to 3A, so that the battery of the mobile terminal cools down slowly after a period of time to prevent the temperature from being too high And affect the charging efficiency of the battery.

In the constant current charging stage, the temperature of the battery in the constant current charging stage is continuously detected within a preset time, for example, if the preset time is 5 minutes, then the temperature of the battery during charging is detected every 5 minutes. When the temperature of the battery does not reach the first preset temperature of 40° C., the charging current of the battery is adjusted to a maximum charging current of 4.5A.

After an interval of 10 minutes, it is detected again that the temperature of the battery is 43°C, which has reached the first preset temperature, and the current power of the battery is detected to be 50% of the battery capacity, and the power range to which it belongs is the second power range, then again Reduce the charging current of the battery to 3A, so that the battery of the mobile terminal cools down slowly after a period of time. And when it is detected that the temperature of the battery drops to the third preset temperature, for example, the third preset temperature is 30° C., the charging current of the battery is re-increased to 4.5A.

Once again, it is detected that the temperature of the battery is 42°C, which has reached the first preset temperature, and it is detected that the current power of the battery is 68% of the battery capacity, and the power range to which it belongs is the second power range, then reduce the battery The charging current is up to 3A, so that the battery of the mobile terminal cools down slowly after a period of time. And when it is detected that the temperature of the battery drops to the third preset temperature of 30° C., the charging current of the battery is re-increased to 4.5A.

After a period of time, it is detected again that the temperature of the battery is 41°C, which has reached the first preset temperature. It is detected that the current power of the battery is 84% of the battery capacity, and the power range it belongs to is the third power range. The charging current of the battery is reduced, and the battery is continuously charged at the reduced charging current until the battery is fully charged. After entering the constant voltage charging phase, the charging current of the battery can be reduced according to the standard charging current value of the constant voltage charging phase until entering the charging termination phase.

In the embodiment of the present invention, by detecting the temperature of the battery during the charging process, when the temperature of the battery reaches the first preset temperature, it detects the power range to which the current power of the battery belongs, wherein each of the power ranges corresponds to a charging strategy, Adjusting the charging current of the battery according to the charging strategy corresponding to the electric quantity interval to which the current electric quantity of the battery belongs can not only control the temperature rise inside the mobile terminal, especially the temperature rise of the battery, but also realize fast charging, and protect the hardware of the mobile terminal At the same time, the charging temperature of the mobile terminal is controlled within a reasonable range to maintain the good charging efficiency of the mobile terminal and meet the user's demand for charging as much power as possible in the mobile terminal in a short time.

The temperature detection module 31 is used to detect the temperature of the battery during charging.

It can be understood that the charging process of lithium batteries is divided into four stages, namely the trickle charging stage (pre-charging), constant current charging stage, constant voltage charging stage and charging termination stage (saturation charging), usually by the mobile terminal The internal charging management chip adjusts the charging parameters for charging the battery according to the charging stage of the lithium battery. Among them, during the constant current charging stage, the lithium battery is in the state of maximum charging current, and the power consumption of the charging management chip is relatively large at this time, which will cause the internal temperature of the mobile terminal, especially the temperature of the lithium battery, to rise. Therefore, in order to improve mobile For the problem that the temperature of the terminal is too high, the temperature detection module 31 can start to detect the temperature of the battery during the charging process after entering the constant current charging phase.

The temperature detection module 31 can detect the temperature of the battery during charging within a preset time. The preset time can be detected by experimenting with temperature changes of the battery of the mobile terminal in various simulated scenarios, and then analyzed to obtain a reasonable preset time. For example, the preset time is 5 minutes, and the temperature of the battery during charging is detected every five minutes.

It can be understood that the first preset temperature can be used to test the influence of different battery temperatures of the mobile terminal on battery performance in various simulated scenarios through experiments, so as to analyze the temperature value that will obviously affect the battery performance as the first preset temperature. a preset temperature. For example, it is detected through experiments that lithium batteries can work in the temperature range of -10 to 55°C, but the more suitable temperature range for charging is 5 to 45°C, especially the temperature range of 10 to 35°C is better, and the temperature range of 5 to 55°C is better. The charging effect is very poor at a temperature range other than 45°C, for example, the first preset temperature is set to 40°C.

In some implementations, the power interval may include a first power interval, a second electric power interval, and a third electric power interval.

The power detection module 32 is further configured to determine that the current power of the battery belongs to the first power range when it is detected that the current power of the battery is less than a first threshold.

For example, the first threshold is 40% of the battery capacity. When the power detection module 32 detects that the current power of the battery is 20% of the battery capacity, the current power of the battery is less than the first threshold, and it is determined that the current power of the battery belongs to the first power range.

For example, the first power range corresponds to a first charging strategy, wherein the first charging strategy may be: maintain the current charging current of the battery, and when it is detected that the temperature of the battery rises to a second preset temperature, reduce the charging current of the battery, wherein the second preset temperature is greater than the first preset temperature.

The power detection module 32 is further configured to determine that the current power of the battery belongs to the second power interval when it is detected that the current power of the battery is greater than or equal to the first threshold and less than the second threshold.

For example, the first threshold is 40% of the battery capacity, and the second threshold is 80% of the battery capacity. When the power detection module 32 detects that the current power of the battery is 50% of the battery capacity, and the current power of the battery is greater than the first threshold and smaller than the second threshold, it is determined that the current power of the battery belongs to the first threshold. Second power range.

For example, the second power range corresponds to a second charging strategy, wherein the second charging strategy may be: reduce the charging current of the battery, and when it is detected that the temperature of the battery drops to the third predetermined When setting the temperature, re-increase the charging current of the battery, wherein the third temperature is lower than the first preset temperature.

The power detection module 32 is further configured to determine that the current battery power belongs to the third power range when it is detected that the current battery power is greater than or equal to the second threshold.

For example, the second threshold is 80% of the battery capacity. When the power detection module 32 detects that the current power of the battery is 85% of the battery capacity, the current power of the battery is greater than the second threshold, and it is determined that the current power of the battery belongs to the third power interval.

For example, the third power range corresponds to a third charging strategy, wherein the third charging strategy may be: reduce the charging current of the battery, and charge the battery with the reduced charging current before the battery is fully charged. Keep charging.

The adjustment module 33 does not regulate the charging current, but maintains the current high current of the battery for charging to meet the needs of the user for the mobile terminal being charged. The need to charge as much power as possible in a short time. However, when the temperature is too high, it is easy to affect the performance of the battery, then when the temperature detection module 31 detects that the temperature of the battery rises to a second preset temperature, the adjustment module 33 reduces the The charging current of the battery makes the battery of the mobile terminal cool down slowly after a period of time, so as to prevent the charging efficiency of the battery from being affected by the temperature being too high.
