The battery is charged according to the first target charging current value.

In an embodiment, the step of acquiring the charge/discharge rate corresponding to the battery temperature may include: determining a preset temperature interval in which the battery temperature falls; and acquiring a charge and discharge rate corresponding to the preset temperature interval. .

In an embodiment, the step of acquiring a charge/discharge rate corresponding to the battery temperature may include: detecting a current battery voltage of the battery; and acquiring the battery when the battery voltage is lower than a preset voltage The charge and discharge ratio corresponding to the temperature.

In an embodiment, the charging control method provided by the embodiment of the present invention may further include the following steps: detecting a current battery of the battery every preset time period during charging the battery according to the first target charging current value a voltage; when the battery voltage is not lower than the preset voltage, charging the battery according to a third target charging current value, the third target charging current value being less than the first target charging current value.

In an embodiment, the step of acquiring the charge/discharge rate corresponding to the battery temperature may include: if the value of the battery temperature is detected to be a non-integer, the value of the battery temperature is rounded off. After the whole process, the rounded value is obtained; according to the rounded value, the corresponding charge and discharge rate is determined.

In an embodiment, the step of detecting a battery temperature of the battery may include: detecting a battery temperature of the battery if it is determined that the terminal is in a charging state.

In an embodiment, the step of detecting a battery temperature of the battery may include: acquiring a voltage value of the thermistor preset in the battery, and calculating a corresponding resistance value according to the voltage value of the thermistor. And obtaining a corresponding battery temperature according to the resistance value.

In an embodiment, a charging control method is provided. As shown in FIG. 1, the flow may be as follows:

In step S101, the battery temperature of the battery is detected.

In the embodiment of the present invention, a thermistor may be built in the terminal, and the thermistor may be built in the battery of the terminal device, and then the voltage value of the thermistor is detected by an analog-to-digital converter to obtain the current temperature of the battery.

As shown in FIG. 2, the thermistor can be built in the battery of the terminal device, and one end of the thermistor R1 is connected to the TEM pin of the battery, and the other end is grounded.

When the voltage value of the thermistor R1 is detected by the digital-to-analog converter to obtain the current temperature of the battery, it should be noted that the resistance value of the thermistor R1 changes correspondingly when the temperature changes. If the digital-to-analog converter detects the voltage value of the thermistor R1, the resistance value of the thermistor can be calculated according to the voltage value, and those skilled in the art should understand that according to the temperature-affected characteristic of the resistance value of the thermistor, The current temperature of the battery can be obtained according to the resistance value, and will not be further described herein.

Therefore, in an embodiment, detecting the battery temperature of the battery in step S101 may include:

Obtaining a voltage value of the thermistor preset in the battery, and calculating a corresponding resistance value according to the voltage value of the thermistor;

A corresponding battery temperature is obtained according to the resistance value.

In an embodiment, in order to improve the accuracy of the temperature detection, the thermistor R1 may be disposed on the circuit board near the battery slot, for example, a position facing the battery slot to accurately sense the temperature change around the battery. To achieve timely response to charge control.

Step S102, when the battery temperature is lower than the preset temperature, the charge/discharge rate corresponding to the battery temperature is obtained.

In an embodiment, in the embodiment of the present invention, a preset temperature value may be preset, for example, 8°, and then the battery temperature is compared with the preset temperature after detecting the current temperature of the battery, and the battery temperature is determined. Whether it is less than the preset temperature, and if so, further obtaining the charge/discharge rate corresponding to the current temperature.

The charge/discharge rate is used to indicate the ratio of the charge and discharge current of the battery, that is, the magnification, and the unit is C, and the charge and discharge rate=charge/discharge current/rated capacity. For example, when a battery with a rated capacity of 100 Ah is discharged with 20 A, the discharge rate is 0.2 C. 1C, 2C, 0.2C is the battery discharge rate: a measure of the speed of discharge. The used capacity is discharged after 1 hour and is called 1C discharge. When the discharge is completed for 5 hours, it is called 1/5=0.2C discharge.

In this embodiment, a plurality of preset temperature intervals may be set in advance, and each of the temperature intervals corresponds to setting a charge and discharge rate. For example, the charge/discharge ratio corresponding to 0°-2° is 0.4C, the charge/discharge ratio corresponding to 3°-5° is 0.3C, and the charge/discharge ratio corresponding to 6°-8° is 0.2C. That is, the step of obtaining the charge and discharge rate corresponding to the battery temperature may include:

Determining a preset temperature range in which the battery temperature falls;

Obtain the charge and discharge rate corresponding to the preset temperature range.

In other embodiments, in order to further improve the accuracy of the solution, the charge/discharge ratio corresponding to different temperatures may be set in advance, for example, the charge-discharge ratio corresponding to 0° is 0.4 C, and the charge-discharge ratio corresponding to 1° is 0.375 C. The charge/discharge ratio corresponding to 2° is 0.325C, the charge/discharge ratio corresponding to 3° is 0.3C, the charge/discharge ratio corresponding to 4° is 0.275C, and the charge/discharge ratio corresponding to 5° is 0.225C, and the charge corresponding to 6° is 6°. The discharge rate was 0.2 C, the charge/discharge ratio corresponding to 7° was 0.175 C, and the charge/discharge ratio corresponding to 8° was 0.125 C. Wherein, if it is detected that the battery temperature of the battery is not an integer, the rounding process may be rounded off, and then the charge and discharge rate corresponding to the battery temperature may be further determined.

Therefore, in one embodiment, the step of obtaining the charge and discharge rate corresponding to the battery temperature may include:

If it is detected that the value of the battery temperature is a non-integer, the rounding value of the battery temperature is rounded off to obtain a rounded value;

Based on the rounded value, the corresponding charge and discharge rate is determined.

Step S103, obtaining a corresponding first target charging current value according to the battery capacity and the charge and discharge rate.

According to the formula charge-discharge rate=charge-discharge current/rated capacity, the first target charge current value is the product of the battery capacity and the charge-discharge rate. For example, 0.3C: 0.3 times the battery capacity, 3000mAh battery, the current is 900mA.

Step S104, charging the battery according to the first target charging current value.

It should be noted that, in the process of charging the battery according to the first target charging current value, it is also required to detect the temperature of the battery in real time, and when the battery temperature changes, it is necessary to acquire a new one according to the new battery temperature. Charging and discharging magnification, and calculating a corresponding charging current value according to the charging and discharging magnification and the battery capacity, so that the terminal charges the battery according to the recalculated charging current value until the charging is completed or the charging is terminated.

In the embodiment of the present invention, a preset time period may be set, so that the terminal automatically generates a detection instruction every the preset time period, and the terminal may detect the battery temperature of the battery according to the detection instruction, and the preset time period may be according to user requirements. Set it yourself, for example, if the preset time period is set to 1 minute, the terminal will detect the current temperature of the battery every 1 minute.

Considering that the charging control method provided by the present scheme is implemented in the process of charging the terminal, it is possible to determine whether the terminal is currently in a charging state before the step of detecting the battery temperature of the battery. If so, the step of detecting the battery temperature of the battery is further performed. For example, a trigger switch can be set for the charging control method of the solution. When the terminal device is detected to be in a charging state, the opening switch is automatically triggered. When the charging is completed or the charging is forcibly interrupted, the above switch is turned off.

Therefore, in an embodiment, detecting the battery temperature of the battery in the above step S101 may include:

If it is determined that the terminal is in a charging state, the battery temperature of the battery is detected.

As can be seen from the above, the embodiment provided by the present invention can detect the battery temperature of the battery. When the battery temperature is lower than the preset temperature, the charge/discharge rate corresponding to the battery temperature is obtained, and then the corresponding first is obtained according to the battery capacity and the charge and discharge rate. The target charging current value is finally charged according to the first target charging current value. The solution can charge the terminal with a corresponding charging current when the battery temperature is low. Therefore, the solution can improve the charging speed of the terminal in a low temperature environment and improve the user experience.

Please refer to FIG. 3. FIG. 3 is a schematic flowchart diagram of another charging control method according to an embodiment of the present invention. The mobile terminal may be a mobile portable device such as a mobile phone or a tablet computer, in particular, a mobile terminal using a lithium ion battery as a power source. Here is an example of a smartphone, including:

In step S201, the smart phone detects the battery temperature of the battery.

In the embodiment of the present invention, before detecting the battery temperature of the battery, it may be first determined whether the mobile phone is in a charging state, and if yes, step S201 is performed, and if not, the process is ended.

When the smart phone is in a charging state, please refer to FIG. 4, where 400 is a power adapter, the power adapter 400 is connected with the smart phone 500 through a USB cable 600, 510 is a USB interface of the smart phone, and 401 is a USB interface of the power adapter 400. The above adapter includes an AC/DC conversion unit 402 and a control unit 403. The AC/DC converting unit 402 is configured to convert a direct current into an alternating current or an alternating current into a direct current.

Among them, the smart phone detects the battery temperature through the built-in temperature sensor in the mobile phone, such as a thermocouple or a thermistor. Taking the thermistor as an example, the thermistor can be placed on the battery. The thermistor is made of a semiconductor material, and most of them have a negative temperature coefficient, that is, the resistance value decreases as the temperature increases. The temperature change causes a large resistance change, so it is the most sensitive temperature sensor. According to the temperature-dependent characteristic of the thermistor resistance, the current temperature of the battery can be obtained according to the resistance value.

Step S202, when the battery temperature is lower than the preset temperature, the smart phone detects the current battery voltage of the battery.

In an embodiment, the preset temperature may be set to 8°, and the smartphone determines whether the battery temperature detected in step S201 is less than 8°. If so, the current battery voltage of the battery is further detected. In one embodiment, the voltage of the battery is acquired in real time during charging of the smartphone via the power adapter. In this embodiment, a preset time period may be set, and then the current battery voltage of the battery is detected every preset time period, wherein the preset time period may be set by the system default or by the user.

In step S203, the smart phone determines whether the battery voltage is lower than the preset voltage. If yes, step S204 is performed, otherwise step S207 is performed.

For example, in the embodiment of the present invention, the preset voltage may be set to 4.1V, and the smart phone determines whether the battery voltage is lower than 4.1V. If it is lower, step S204 is performed, and if not, step S207 is performed.

Step S204, the smartphone acquires a first charge/discharge rate corresponding to the battery temperature.

When the battery voltage is lower than 4.1V, the smart phone acquires the first charge/discharge rate corresponding to the battery temperature, for example, 0.3C, that is, 0.3 times the battery capacity. In this embodiment, a plurality of preset temperature intervals may be set in advance, and each of the temperature intervals corresponds to setting a charge and discharge rate.

Step S205, the smartphone acquires a corresponding first target charging current value according to the battery capacity and the first charging/discharging ratio.

The first target charging current value is the product of the battery capacity and the charge and discharge rate. For example, the charge/discharge rate is 0.3 C: 0.3 times the battery capacity, 3000 mAh cell, and the first target charge current value is 900 mA.

Step S206, the smartphone charges the battery according to the first target charging current value.

In one embodiment, the battery temperature of the mobile phone battery can also be detected in real time during charging of the smartphone. When the temperature of the battery changes, the charge/discharge rate corresponding to the changed battery temperature can be obtained, and the charge current value is recalculated and charged according to the current value.

Step S207, the smartphone acquires a second charge/discharge rate corresponding to the low current charge.

When the battery voltage is not lower than 4.1V, the smart phone acquires a second charge/discharge rate corresponding to the battery temperature, for example, 0.15C, that is, 0.15 times the battery capacity.

Step S208, the smartphone acquires a second target charging current value corresponding to the low current charging according to the battery capacity and the second charging/discharging ratio.

In step S209, the smartphone charges the battery according to the second target charging current value.

In an embodiment, during the charging of the battery according to the first target charging current value, the current battery voltage of the battery may also be detected every preset time period;

When the battery voltage is not lower than the preset voltage, the battery is charged according to the third target charging current value. The third target charging current value is smaller than the first target charging current value. The third target charging current value may be the same as the second target charging current value.

As can be seen from the above, the embodiment of the present invention can detect the battery temperature of the battery by the smart phone, and when the battery temperature is lower than the preset temperature, detect the current battery voltage of the battery, determine whether the battery voltage is lower than the preset voltage, and if so, obtain the battery. The temperature corresponds to the first charge/discharge rate, and the corresponding first target charging current value is obtained according to the battery capacity and the first charge and discharge rate, and then the smart phone charges the battery according to the first target charging current value. If the battery voltage is not lower than the preset voltage, the smart phone acquires a second charging/discharging ratio corresponding to the low current charging, and then obtains a second target charging current value corresponding to the low current charging according to the battery capacity and the second charging and discharging ratio, and The second target charging current value charges the battery. The solution can charge the terminal with a corresponding charging current when the battery temperature is low. Therefore, the solution can improve the charging speed of the terminal in a low temperature environment and improve the user experience.
