Step S20: adjusting the charging power of a charger according to the voltage temperature parameter, and acquiring the front-end current output by the charger in real time;

it can be understood that, the charging power of the charger, i.e. the voltage and current output by the charger, needs to be increased to charge the mobile terminal quickly, i.e. the charging power is increased, which causes the charging devices (the charger and the mobile terminal) to generate heat, resulting in a large charging loss and a reduction in charging efficiency.

The front-end current may be a current output by the charger to the mobile terminal, or a current between a charging interface of the charger and a charging IC of the mobile terminal.

In a specific implementation, in order to solve the problem of heat generation of the charging device as much as possible and reduce the charging loss, the mobile terminal may dynamically adjust the charging power of the charger according to the voltage temperature parameters (such as the battery voltage, the temperature of the battery to be charged, the temperature of the charging chip, and/or the temperature of the loading board of the charging chip).

For example, when the battery voltage is large, i.e., the battery is charged quickly, the charging power is reduced; when the battery voltage is small, the charging power is increased.

For example, when the temperature of the battery to be charged or the temperature of the charging chip mounting plate is high, the charging power is reduced to reduce the amount of heat generated, and when the temperature of the battery to be charged is low, the charging power is appropriately increased to increase the charging speed. In practical application, the mobile terminal can obtain the current between the charging interface of the charger and the charging IC of the mobile terminal in real time after completing the dynamic adjustment of the charging power, that is, the front-end current, and then adjust the working state of the charging chip according to the magnitude of the front-end current.

Step S30: and adjusting the working state of the charging chip according to the front-end current.

It can be understood that the charging chip is a charging IC provided in the mobile terminal. According to different actual charging scenarios, the number of the charging chips in this embodiment may be set as a single charging IC, may also be set as two charging ICs (e.g., a master charging IC and a slave charging IC), and may also be set as more than two charging ICs (e.g., a master charging IC and two or more slave charging ICs), which is not limited in this embodiment.

In addition, it should be noted that the operating state in this embodiment includes an on state (power-on state), an off state (power-off state), or a state of operating according to other charging requirements, and does not only refer to the operating state after the charging chip is powered on.

The charging device aims to solve the technical problems that the charging efficiency is not high and the charging loss is overlarge in the existing charging technology. In this embodiment, the mobile terminal dynamically adjusts the operating state of the charging chip according to the magnitude of the front-end current, that is, turns on or off the charging chip, thereby implementing dynamic management of the charging IC under different charging powers, and further reducing the heating value of the charging device in the charging process.

Taking two charging ICs (a master charging IC and a slave charging IC) as an example, when the front-end current is large, the temperature of the charger and the mobile terminal is usually increased (the charger and the mobile terminal are hot), and the charging efficiency is affected. For such a situation, the mobile terminal of this embodiment can enter the half-voltage charging mode by simultaneously turning on the main charging IC and the slave charging IC, thereby reducing the voltage on the branch where each charging IC is located, and increasing the current output by the charging chip, so as to implement temperature reduction without changing the charging power. It should be noted that, in the half-voltage charging process of this embodiment, the main charging IC is always turned on, and the mobile terminal can dynamically adjust the operating state of the secondary charging IC according to the magnitude of the front-end current, so as to meet the cooling requirement in the high-power charging scenario.

Alternatively, it is considered that the charging manner of the single main charging IC can only reduce the amount of heat generation by intermittent charging (i.e., by temporarily stopping charging when the temperature is too high, and resuming charging when the temperature is lowered) or by reducing the charging power, reducing the charging loss. Therefore, as an implementation manner, the charging chip in this embodiment may be configured as a master charging chip and at least two slave charging chips;

accordingly, the step S30 may include:

step S301: and adjusting the working state of the main charging chip and/or the working states of at least two slave charging chips according to the front-end current.

It should be noted that, in the present embodiment, the charging chip is dynamically controlled by configuring a master-slave mode, so that the problem of temperature rise during the charging process of the mobile terminal can be more effectively solved.

Taking a master and a slave as an example, in a normal charging process, the mobile terminal firstly starts the master charging IC for charging, when the charging power output by the charger is increased and the front-end current is increased to be higher than a set current threshold, the first slave charging chip can be started, if the front-end current is continuously increased at the moment, in order to ensure that the currents output from different charging ICs are basically the same, the second slave charging IC can be started, the increased current is distributed to the branches of the second slave charging IC, so that the output currents of the three charging branches are ensured to be the same, and the heating and temperature rise under the condition of high-power charging are inhibited.

Optionally, in order to more canonically regulate and control the operating state of the charging chip, as another implementation manner of the step S301, in this embodiment, the mobile terminal may accurately determine the on or off timing of the charging IC by presetting an off current. Specifically, the mobile terminal may adjust the working state of the master charging chip and/or the working states of at least two slave charging chips according to the front-end current and a preset cutoff current. For example, when the front-end current is greater than 2 times the preset off-current, the first slave charging IC may be tried to be turned on, and when the front-end current is greater than 3 times the preset off-current, the second slave charging IC may be tried to be turned on.

The charging power of the charger is dynamically adjusted through the voltage temperature parameter in the charging process, so that the charging power of the charger can be dynamically adjusted under different charging voltage/temperature scenes, the charging efficiency is improved, meanwhile, the front-end current output by the charger is obtained in real time after the charging power is adjusted, then the working state of the charging chip is adjusted according to the front-end current, the problem that a single charging chip generates heat under a high-power charging scene is avoided, and the charging loss is effectively reduced.

Referring to fig. 4 and 5, fig. 4 is a flowchart of a second embodiment of the charging control method provided in the present application. Fig. 5 is a charging architecture diagram of a second embodiment of the charging control method proposed in the present application.

As shown in fig. 5, in this charging configuration, a switch IC, a master IC, a slave IC1, and a slave IC2 are connected to the charger. Wherein, main IC, from IC1 and follow IC2 belong to charging IC, and switch IC user opens the charging or closes the charging.

Based on fig. 5, in this embodiment, the adjusting, by the mobile terminal, the working state of the master charging chip and/or the working states of the at least two slave charging chips according to the front-end current and the preset off-current may include:

step S3011: acquiring current lifting information of the front-end current;

it should be understood that, the current rising and falling information, i.e. the changing direction of the current magnitude, and the current rising continuously means that more slave charging ICs are required to be turned on, and the current falling continuously can be considered to turn off some slave charging ICs, which is beneficial to reducing the working time of the charging ICs and prolonging the service life of the charging ICs.

Step S3012: and adjusting the working state of the main charging chip and/or the working states of at least two slave charging chips according to the current lifting information and a preset cut-off current.

In a specific implementation, the mobile terminal determines current rise and fall information by obtaining magnitudes of front-end currents of adjacent time periods, for example, magnitudes of front-end currents before 10 seconds, before 5 seconds and at present, and if the three are sequentially reduced, it may be determined that the front-end current is in a falling state, and otherwise, if the three are sequentially raised, it may be determined that the front-end current is in a rising state. According to the lifting information of the front-end current, the working state of the main charging chip and the working state of each secondary charging chip can be flexibly and intelligently adjusted by combining with the preset cut-off current.

As an implementation manner, when the front-end current rises to a preset cutoff current of a first preset multiple, the mobile terminal of this embodiment selects any one of the at least two slave charging chips to turn on, and maintains the current operating state of the master charging chip.

The first preset multiple may be 2 times, that is, when the front-end current rises to 2 times of the preset off-current, one of the charging chips is turned on. Because the main charging IC is always turned on when the charging is not finished, only the main charging chip needs to be continuously turned on at the moment.

As another implementation manner, when the front-end current rises to the preset cutoff current of the second preset multiple, the mobile terminal of this embodiment selects any one of the slave charging chips that are not turned on to turn on, and maintains the current operating state of the master charging chip.

The second preset multiple may be 3 times, that is, when the front-end current rises to 3 times of the preset off-current, any one of the slave charging chips that is never turned on is turned on. Similarly, the main charging chip is kept on.

Optionally, in order to improve the charging efficiency as much as possible and implement intelligent charging of the battery, in this embodiment, the mobile terminal further determines whether the front-end current is in a continuously rising state according to the current rise and fall information; if yes, calculating the current difference between the front-end current and the target current in real time, and adjusting the charging power of the charger according to the current differential state.

The target current may be a preset reference current for determining whether the charging power needs to be adjusted. When the current is small (namely, the current difference between the front-end current and the target current is large), the charging power can be rapidly increased, the charging efficiency is improved, and when the front-end current is increased to be close to the target current (namely, when the current difference between the front-end current and the target current is small), the increasing rate of the charging power is slowed down, namely, the charging power is slowly increased, so that rapid charging is realized as much as possible.

Optionally, in order to implement dynamic control on the charging chip, in this embodiment, when the mobile terminal determines that the front-end current is in a state of being continuously reduced at a certain time, the mobile terminal may obtain a current value of the started secondary charging chip when the front-end current is reduced to the preset cutoff current smaller than the second preset multiple; and determining a secondary charging chip to be closed from the opened secondary charging chip according to the current value of the opened secondary charging chip, and closing the chip to be closed.

It can be understood that when the slave charging ICs meeting the current charging requirement are all turned on, the charging power can be slowly reduced as the battery level increases until the charging is completed. In the process of reducing the charging power, the front-end current is also reduced correspondingly, and at the moment, some charging ICs which are already turned on can be turned off according to the reduction degree of the front-end current. For example, when the front-end current is reduced to a preset off-current smaller than 3 times, one of the slave charging ICs that has been turned on may be turned off.

The slave charging IC to be turned off in this embodiment may be determined according to the current value flowing through the slave charging chip, or one slave charging IC may be arbitrarily selected, which is not limited in this embodiment. Optionally, in order to ensure that the charging power does not suddenly change, as an implementation manner, the mobile terminal may obtain a flowing current value of the main charging chip, and then determine and close the slave charging chip to be closed from the opened slave charging chip when the flowing current value of the main charging chip and the flowing current value of the opened slave charging chip meet a preset condition.

Wherein the preset conditions include: and a target flowing current value is larger than other flowing current values in the flowing current value of the main charging chip and the flowing current value of the started auxiliary charging chip. Taking a master two slave charging ICs as an example, when the current (i.e. the above-mentioned flowing current value) passed by one of the three charging ICs is larger than the currents passed by the other two charging ICs, the slave charging chip to be turned off is determined from the turned-on slave charging chips and turned off.

Optionally, in view of the fact that current may be unstable occasionally during the actual charging process, in order to implement accurate regulation and control on the charging IC and avoid misoperation, the preset conditions may further include: the current value of the main charging chip and the current value of the started auxiliary charging chip have a target current value larger than other current values, and the duration of the target current value larger than other current values exceeds a preset duration. Similarly, taking a master charging IC and two slave charging ICs as an example, when the current passing through one of the three charging ICs is greater than the currents passing through the other two charging ICs, the duration that the flowing current value is greater than the other flowing current values is counted, and if the duration exceeds the preset duration, the slave charging chip to be turned off is determined from the turned-on slave charging chips and is turned off.

In addition, as a determination manner of the slave charging IC to be turned off, in this embodiment, the mobile terminal may select a minimum flowing current value from the flowing current values of the turned-on slave charging chips; and then taking the slave charging chip corresponding to the minimum flowing current value as a slave charging chip to be closed, and closing the chip to be closed. That is, the slave charging IC having a small current value is turned off.

Optionally, if the front-end current is continuously reduced to a preset cut-off current smaller than the first preset multiple, closing the currently opened slave charging chip; and when the front-end current is reduced to be less than the preset cut-off current, closing the main charging chip.

In the embodiment, the multiple relation between the front-end current and the cut-off current and the current lifting information of the front-end current are used as the basis for judging whether the charging IC is turned on or turned off in the above mode, so that the temperature rise problem in the charging process can be effectively solved, the charging devices (the charger and the mobile terminal) are kept at a proper temperature for charging, the problem of charging loss caused by temperature rise of the charging devices is avoided, and the charging efficiency is improved.

Referring to fig. 6, fig. 6 is a flowchart of a third embodiment of a charging control method according to the present application. Before the step S10, the present embodiment further includes:

step S01: acquiring the battery voltage of a battery to be charged;

it should be noted that the battery voltage may be a current voltage value of a (to be charged) battery of the mobile terminal, which may be characterized by a percentage of a remaining capacity of the battery to a total battery capacity.

Step S02: and setting the charging voltage and the initial current of a charger according to the battery voltage, and starting a main charging chip in a charging chip to charge the battery to be charged.

It will be appreciated that when the battery voltage is high, for example (battery charge is still 90%) the battery is substantially at full charge, the charging voltage and charging current of the charger need not be set too high, and when the battery voltage is low, for example (battery charge is only 5%), the user's demand for rapid charging is undoubtedly strong, and the initial charging voltage and charging current for the charger needs to be set a bit larger. Therefore, in this embodiment, the mobile terminal sets an (initial) charging voltage and an initial current of the charger according to the battery voltage of the battery to be charged, and simultaneously turns on the main charging chip of the charging chips to charge the battery to be charged.

Optionally, in this embodiment, before performing the above steps S01-S02, the mobile terminal further initializes the charging chip, that is, configures the charging chip into a master-slave mode.

Optionally, the mobile terminal may obtain a communication address of each charging chip, and then set a master charging chip and at least two slave charging chips in the charging chip according to the communication address.

The communication address may be an I2C address of the charging chip, or another communication address having a similar function and capable of being used to determine whether the charging chip belongs to the master charging chip or the slave charging chip, which is not limited in this embodiment.

Optionally, in view of the fact that a situation that the charging chip is damaged and unavailable may exist in an actual situation, in order to effectively determine whether the charging chip is damaged, in this embodiment, the mobile terminal may further send a status check data packet to the corresponding charging chip according to the communication address, and detect whether the charging chip responds to the status check data packet; and judging that the charging chip which does not respond to the state verification data packet is damaged according to the detection result, and setting a main charging chip and at least two slave charging chips in the undamaged charging chips according to the communication address.

It should be noted that the check data in the status check data packet may be set according to an actual situation, and once it is found that the charging chip does not respond to the status check data packet, it indicates that the charging chip is damaged. Certainly, in order to ensure the accuracy of the detection result, the state check data packet may be sent to the charging chip for multiple times, and if no response is made, it may be determined that the charging chip is damaged, and at this time, a master charging chip and at least two slave charging chips need to be arranged from the undamaged charging chips.

Optionally, in this embodiment, the mobile terminal further performs protocol (i.e. charging specification) identification on the connected charger before performing the above steps S01-S02, and then performs charging control through I2C communication when the protocol identification is completed.

Specifically, before the step S01, the charging control method of the present embodiment further includes:

step S1: carrying out protocol identification on a currently accessed charger, and sending a protocol negotiation request to the charger according to a protocol identification result;

step S2: when detecting that the charger completes the response to the protocol negotiation request, sending an authentication instruction to the charger;

step S3: and when a data packet returned by the charger based on the authentication instruction is received, verifying the data packet, and when the data packet passes the verification, establishing communication connection with the charger.

It should be noted that, a standard USB charger usually shorts a D + line and a D-line in the charger according to the BC1.2 specification, and a standard charger that shorts a D + line and a D-line in the charger according to the BC1.2 specification cannot support fast charging. Therefore, in this embodiment, when the mobile terminal accesses the charger, the mobile terminal identifies the charging protocol, identifies whether the mobile terminal can support fast charging, and if the mobile terminal can support fast charging, the mobile terminal sends a protocol negotiation request to the charger, so that the charger adjusts the charging protocol according to the request to support fast charging.

In a specific implementation, the mobile terminal may perform protocol identification on a currently accessed charger, and if it is found that the charger can support fast charging, a protocol negotiation request is sent to the charger so that the charger does not perform charging according to a conventional charging protocol (BC1.2 specification), but a fast charging mode is used to perform charging on the mobile terminal. When the charger completes protocol replacement, namely response to the protocol negotiation request, the mobile terminal sends an authentication instruction to the charger, then when receiving a data packet returned by the charger based on the authentication instruction, the mobile terminal performs identification verification on the message in the data packet, and establishes I2C communication connection with the charger when the verification is passed.

In this embodiment, the initial charging voltage and current, that is, the initial charging power, after charging can be dynamically set according to the actual battery voltage of the charged mobile terminal, and then the charging control is performed based on the initial charging power.

Referring to fig. 7, fig. 7 is a flowchart illustrating a fourth embodiment of a charging control method according to the present application. Based on the foregoing embodiments, in this embodiment, the step S10 may include:

step S101: and acquiring the battery voltage and/or the charging temperature in the charging process.

Accordingly, the step S20 includes:

step S201: and adjusting the charging power of the charger according to the battery voltage and/or the charging temperature, and acquiring the front-end current output by the charger in real time.

As described in the above first embodiment, the charging temperature in this embodiment may be the temperature of the charging device (charger and mobile terminal). Wherein, the temperature of the charger can be obtained after the mobile terminal establishes the I2C communication connection with the charger. The temperature of the mobile terminal may include a temperature of a battery to be charged, a temperature of a charging chip, and/or a temperature of a loading board of the charging chip. In this embodiment, the charging temperature used as a basis for adjusting the charging power of the charger needs to comprehensively consider the obtained temperature parameters, mainly the temperature of the charging chip, and the other temperature parameters are used to calculate a weighted average temperature, and then the charging power of the charger is adjusted according to the weighted average temperature.

Optionally, the mobile terminal may obtain a battery voltage during charging; and/or acquiring the temperature of a battery to be charged, the temperature of a charging chip and/or the temperature of a charging chip loading plate in the charging process through a preset temperature sensor, and then adjusting the charging power of the charger according to the voltage of the battery and/or the charging temperature.

Since the charger is mostly connected with the charging port of the mobile terminal through the charging wire, for the temperature of the charger, the mobile terminal can send a temperature acquisition command to the charger after the mobile terminal establishes an I2C communication connection with the charger, so that the charger feeds back the temperature of the charger when receiving the temperature acquisition command. Therefore, the temperature of the charger can be acquired.

Referring to fig. 8, fig. 8 is a charging architecture diagram of a fourth embodiment of the charging control method proposed in the present application. As shown in fig. 8, in order to implement accurate control of the charging chips, in this embodiment, on the basis of fig. 5, a corresponding controller or control circuit is configured for each charging chip, and these controllers or control circuits are mainly used to ensure that the impedances of the turned-on charging ICs are matched as much as possible, so that the currents flowing through the different charging ICs are in a relatively balanced state, and thus the heating values of the charging ICs are not much different, and the problem of charging heating is better solved.

Based on the foregoing embodiments, the present application further provides a charging control method, including the following steps:

step 11: collecting front-end current output by a charger, wherein the front-end current is current between the charger and a charging chip;

step 12: acquiring current lifting information of the front-end current;

step 13: and adjusting the working state of the charging chip according to the current lifting information and a preset cut-off current.

It should be noted that, the method of the present embodiment is applied to the adjustment of the state of the charging chip during the charging process of the mobile terminal, and the execution main body of the charging control method may also be the mobile terminal 100 (hereinafter referred to as the mobile terminal). The basic logic and principle of the charging control method of the embodiment are similar to those of the first to fourth embodiments, and the difference is that the embodiment is applied to the state adjustment of the charging chip in the charging process.

It can be understood that the current rise and fall information, i.e., the direction of change of the current magnitude. Under the scene that only one charging IC is available, charging control is achieved through current lifting information and cut-off current, compared with the existing charging mode of direct voltage reduction, the charging control is more intelligent, and charging efficiency is higher.

In the scenario of a master charging IC with multiple slaves, the current continuously rises, which means that more charging ICs are required to be turned on, and the current continuously falls, so that some charging ICs can be considered to be turned off, which is beneficial to reducing the working time of the charging ICs and prolonging the service life of the charging ICs. Therefore, in the embodiment, the mobile terminal dynamically adjusts the working state of the charging chip by acquiring the front-end current output by the charger in real time and then according to the current lifting information of the front-end current and the preset cut-off current, so that the problem that the charging device generates heat when the charging chip flows through a large current in the prior art can be effectively solved.

Optionally, in this embodiment, the charging chip includes a master charging chip and at least two slave charging chips;

acquiring a current value flowing through the main charging chip;

and adjusting the working state of the main charging chip and/or the working states of at least two slave charging chips through a preset controller according to the current lifting information and a preset cut-off current.
