Fig. 1 is a schematic flowchart of a charging control method according to an embodiment of the present disclosure. As shown in fig. 1, the charge control method may include the steps of:
The charging state information may include: voltage values, charging current values, and the like, which are not limited in this disclosure.
It is understood that the voltage value, may be indicative of the voltage condition of the battery; the charging current value can represent the current condition of the battery.

The present disclosure is not limited thereto.
The electronic equipment comprises a battery, a bidirectional voltage conversion circuit and a power management integrated circuit, wherein the battery is sequentially connected with the bidirectional voltage conversion circuit and the power management integrated circuit.
Optionally, the controller may further identify the charger and determine whether the charger is in place when the charger is connected to the circuit. In the case where the charger is in place, current charge state information of the battery, etc. is acquired, which is not limited by the present disclosure.
And step 102, determining a target charging mode according to the charging state information.
The target charging mode may be multiple, for example, the target charging mode may be a constant-current charging mode, or may also be a constant-voltage charging mode, and the like, which is not limited in this disclosure.
It is understood that the constant current charging refers to a charging mode in which a charging current value is maintained at a constant value, and the constant voltage charging refers to a charging mode in which a voltage value is maintained at a constant value.
Alternatively, the target charging mode may be determined to be the constant current charging mode when the voltage value is smaller than the first threshold value.
The first threshold may be a preset value, or may also be adjusted according to needs, and the like, which is not limited in this disclosure.
For example, if the first threshold is 3.5 volts (V), the voltage value is 2V, and it is smaller than the first threshold, the target charging mode may be determined to be a constant current charging mode, and the like, which is not limited in this disclosure.
Alternatively, the target charging mode may be determined to be the constant-voltage charging mode when the voltage value is greater than or equal to the first threshold value and the charging current value is greater than the second threshold value.
The first threshold and the second threshold may be preset values, or may be adjusted according to needs, and the like, which is not limited in this disclosure.
For example, the first threshold is 3.8V, the second threshold is 0.2 ampere (a), the voltage value is 3.85V, which is greater than the first threshold, the charging current value is 0.5A, which is also greater than the second threshold, and at this time, it may be determined that the target charging mode is a constant voltage charging mode, and the like, which is not limited in this disclosure.
Alternatively, the target charging mode may be determined as the end of charging when the voltage value is greater than or equal to the first threshold value and the charging current value is less than the second threshold value.

And 103, controlling the voltage value or the charging current value of the battery according to the target charging mode.
For example, if the target charging mode is the constant current charging mode, the charging current value of the battery may be controlled to be adjusted to a charging current value corresponding to the constant current charging mode, and so on. Or the voltage value may be controlled, for example, as the constant current charging mode proceeds, the voltage value of the battery may be increased, and the like, which is not limited in this disclosure.
Alternatively, the target charging mode may be a constant voltage charging mode, and the charging current value of the battery may be controlled. For example, as the constant voltage charging mode is performed, the charging current value of the battery may be reduced, so as to ensure charging safety, and the like, which is not limited in this disclosure.
It should be noted that the charging control method provided by the present disclosure may be applied to any charging system, and the present disclosure does not limit this.

In addition, the operation mode of the bidirectional voltage conversion circuit may be a boost mode or a buck mode. Thus, the bi-directional voltage conversion circuit may operate in a boost mode during battery charging.
It is understood that in actual implementation, the circuit structure of the charging system may be adjusted as needed. For example, a connector or the like may be added to the charging system, which is not limited in this disclosure.
According to the embodiment of the disclosure, the current charging state information of the battery is acquired first, then the target charging mode can be determined according to the charging state information, and the voltage value or the charging current value of the battery is controlled according to the target charging mode. Therefore, the corresponding target charging mode is determined according to the acquired current charging state information of the electric package, and then the battery can be controlled based on the target charging mode, so that the charging requirements of the battery under different conditions can be met, and the charging safety of the battery is guaranteed.
Fig. 2 is a schematic flowchart of a charging control method according to an embodiment of the disclosure. As shown in fig. 2, the charge control method may include the steps of:
Optionally, the preset duration may be a default value set in advance.
For example, the preset time duration is 5 seconds (second, s), and at the beginning of charging, the current charging state information of the battery may be acquired every 5 s.
Or, if the time of obtaining the charging state information of the battery last time is the time t0, the current time is the time t1, and the time interval between the two is 5 seconds, that is, the time interval between the two reaches the preset time length, the current charging state information of the battery can be obtained.
It should be noted that the above examples are only examples, and cannot be taken as limitations on the preset time duration, the manner of acquiring the current state of charge information of the battery, and the like in the embodiments of the present disclosure.
Optionally, the preset time duration may also be determined according to the current electric quantity of the battery.
It is understood that the larger the current charge of the battery, the shorter the preset time period may be, and the smaller the current charge of the battery, the longer the preset time period may be.
For example, if the full power capacity of the battery is 20 watts (watt, W), the current capacity of the battery is 12W, the preset time duration may be determined to be 3s, and if the time when the charging state information of the battery was obtained last time is t0, the current charging state information of the battery may be obtained at the time (t 0+3 s), and the disclosure does not limit this.
Optionally, the preset time duration may also be determined according to the charging current value.
It is understood that, during the charging process, the preset time period may be determined according to the previously received charging current value.
For example, if the charging current value is larger, the preset time period may be longer, and if the charging current value is smaller, the preset time period may be shorter. Or, different charging current values correspond to different preset time lengths, and the like, which is not limited in this disclosure.
For example, if the charging current value is 1A, the corresponding preset time period may be determined to be 2s, and if the charging current value is 0.8A, the corresponding preset time period may be determined to be 1s, and so on, which is not limited in this disclosure.
Further, the preset time duration may also be determined by the current electric quantity and the charging current value of the battery together, at this time, corresponding weights may be set for the electric quantity and the charging current value, then the electric quantity and the charging current value are multiplied by the corresponding weights and then added, and the preset time duration is determined according to the result of the addition.
And step 203, controlling the charging current value to gradually decrease by a preset step length under the condition that the target charging mode is the constant voltage charging mode.
The preset step length may be a default value set in advance, or may also be adjusted according to needs, and the like, which is not limited in the present disclosure.
Optionally, the charging current value may be controlled to gradually decrease by a preset step length according to a certain frequency until the target charging current value is reached.
The frequency may be set in advance, or may also be adjusted according to needs, and the like, which is not limited in this disclosure.
For example, the preset step length is 100mA, the target charging mode is constant voltage charging, and the charging current value is 1000mA, the charging current value may be reduced according to the step length of 100mA every 1s until the charging current value is reduced to 100mA, and the like, which is not limited in the disclosure.
Optionally, the charging state information may further include a battery temperature, so that the current charging current value may be reduced when the battery temperature is greater than a third threshold, thereby improving the safety of the battery during the charging process and reducing potential safety hazards.
It is understood that a temperature sensor, a thermistor, etc. may be included in the electronic device, such that the battery temperature may be determined according to the temperature sensor, or the battery temperature may also be determined according to the thermistor, etc., which is not limited by the present disclosure.
The third threshold may be a preset value, for example, 40 ℃, 45 ℃, and the like, which is not limited in this disclosure.
For example, the third threshold is 40 ℃, the battery temperature is 43 ℃, and the third threshold is higher than the battery temperature, so that the current charging current value can be reduced, the charging hidden trouble caused by overhigh temperature can be avoided, and the charging safety can be guaranteed
It should be noted that the above examples are merely illustrative, and are not intended to limit the third threshold value, the battery temperature, and the like in the embodiments of the present disclosure.
The charging control method provided by the present disclosure may be applied to any charging system or charging scenario, and the present disclosure does not limit this.
For example, in the circuit structure diagram of the charging system shown in fig. 2A, the charging system may include a power management integrated circuit, a bidirectional voltage conversion circuit, and a controller.
The first input terminal of the PMIC may be configured to receive an input voltage, the first output terminal of the PMIC may be connected to the first input terminal of the bidirectional voltage conversion circuit, and the first output terminal of the bidirectional voltage conversion circuit is connected to the battery.
Optionally, the second input terminal of the PMIC may be connected to the second output terminal of the bidirectional voltage conversion circuit, the second output terminal of the PMIC may be connected to the power supply terminal of the controller, and the second input terminal of the bidirectional voltage conversion circuit is connected to the battery.
Wherein, the PMIC can be any model. For example, the PMIC may include the MT6360, or may also include other chips or structures having the same function as the MT6360, and the disclosure is not limited thereto.
In addition, the bidirectional voltage conversion circuit may be any circuit or chip that can implement bidirectional voltage conversion, which is not limited in this disclosure.
It is understood that, in the embodiment of the present disclosure, the controller may be configured to control the charging state of the battery.
For example, in the process of charging the battery, if the voltage value of the battery is 1V and is smaller than the first threshold set in advance, if the controller determines that the target charging mode is the constant current charging mode, the charging state of the battery may be controlled to be the constant current charging mode.
Or the voltage value of the battery is 3.9V which is larger than the set first threshold value of 3.8V, the charging current value is 1V which is larger than the set second threshold value of 0.5V, and the charging state of the battery can be controlled to be in a constant voltage charging mode.
It should be noted that the above examples are merely illustrative, and are not intended to limit the voltage value, the charging current value, the manner of controlling the charging state of the battery, and the like in the embodiments of the present disclosure.
Optionally, in this embodiment of the present disclosure, the controller may further specifically be configured to: and controlling the bidirectional voltage conversion circuit to work in a boosting mode in the battery charging process, and controlling the bidirectional voltage conversion circuit to work in a reducing mode in the battery discharging process.
For example, the step-up conversion ratio of the bidirectional voltage conversion circuit is 1:2, and during the charging process of the battery, the controller can control the bidirectional voltage conversion circuit to operate in the step-up mode, that is, the battery is charged according to the mode of 1:2. Or, the step-down conversion ratio of the bidirectional voltage conversion circuit is 2:1, and in the battery discharging process, the controller can control the bidirectional voltage conversion circuit to work in the step-down mode, that is, according to the ratio of 2: the mode 1 discharges.
It should be noted that the above examples are only illustrative, and should not be taken as limitations on the operation modes of the bidirectional voltage conversion circuit in the embodiments of the present disclosure.
It is understood that, in the actual implementation process, the circuit structure of the charging system may be adjusted as needed, so that the charging system may also include other circuit structures, which is not limited in this disclosure.
For example, in the schematic structure of the charging circuit shown in fig. 2A, the PMIC may include an MT6360, and the bidirectional voltage conversion circuit may be a MAX77938. Or the PMIC may also be any other power management integrated circuit of any type, and the bidirectional voltage conversion circuit may also be any other circuit or chip that can implement bidirectional voltage conversion, and the like, which is not limited in this disclosure.
In conjunction with the charging control method provided by the present disclosure, in fig. 2A, the controller may obtain current charging state information in the battery, then determine a target charging mode according to the charging state information of the battery, and then control the charging state of the battery based on the target charging mode. Therefore, when the battery is charged, the controller can control the MAX77938 to work in a boosting mode of 1:2, and therefore the battery is charged. In the process of discharging the battery, the controller can control the MAX77938 to work in the voltage reduction mode of 2:1 to realize discharging, and the process does not need a third-party charging Integrated Circuit (IC) chip with a voltage boosting function and 2:1, thereby effectively reducing hardware cost and development period.
