In this application scenario, the electronic device includes two device bodies, and in an alternative embodiment, the first device body may be a device body on the side including the back surface, and the second device body may be a device body on the side including the sub-screen.

Referring to fig. 3, fig. 3 is a schematic circuit structure diagram for reverse charging in The electronic device, as shown in fig. 3, a first battery 3011 and a coil 3012 are built in The first device body 301, the coil 3012 may be disposed directly above The first battery 3011, the coil 3012 may be used for transmitting and receiving wireless charging signals and power, an interface 3013 is further disposed On The first device body 301, such as The bottom, the interface 3013 may be used for wired charging and reverse wired OTG (On-The-Go) charging, the interface 3013 may be a Type-C interface, and a second battery 3021 is built in The second device body 302.

In addition, a temperature sensor for detecting the respective temperatures may be provided on or beside the first and second batteries 3011 and 3021, respectively, and the temperature sensor may be a thermistor having a negative temperature coefficient (Negative Temperature Coefficient, NTC).

The reverse charging type of the electronic device may refer to a reverse charging scenario of the electronic device, where the reverse charging of the electronic device refers to switching the electronic device to a mobile power supply to perform discharging, so as to perform charging for other electronic devices.

And the reverse charging scenario may generally include a reverse wireless charging only, a reverse OTG charging only, and a coexistence scenario of reverse wireless charging and reverse OTG charging.

The reverse charging type of the electronic device can be determined by one reverse charging identifier, and the parameter values of the reverse charging identifiers are different, so that the reverse charging types of the electronic device are also different.

The parameter value of the reverse charging identifier can be determined by detecting a reverse charging scene of the electronic device, for example, when the back surface of the electronic device is detected to be close to another electronic device and the interface is not connected with other electronic devices under the condition that the electronic device starts a reverse charging function, the parameter value of the reverse charging identifier can be determined to be a value 0, and the reverse charging type of the electronic device is characterized by only including reverse wireless charging.

For another example, when it is detected that another electronic device is connected to the interface of the electronic device and the back surface is not close to the other electronic device, it may be determined that the parameter value of the reverse charging identifier is a value 1, and the reverse charging type of the electronic device includes only reverse OTG charging.

For example, when it is detected that the interface of the electronic device is connected with another electronic device and the back surface is close to the other electronic device, the parameter value of the reverse charging identifier may be determined to be a value 2, and the reverse charging type of the electronic device includes reverse wireless charging and reverse OTG charging.

Step 102, executing a first reverse charging operation according to the reverse charging type;

In this step, the first reverse charging operation performed is different from the second reverse charging operation, and when the reverse charging type includes only reverse wireless charging, the first reverse charging operation performed may be charging the coil using the second battery and performing reverse charging through the coil.

In practical applications, as shown in fig. 3, the first switch 3032 connected to the coil 3012 by the second battery 3021 may be controlled to be closed, so that the second battery 3021 is connected to the coil 3012, and the first switch 3031 connected to the coil 3012 by the first battery 3011 is controlled to be turned off, so that the first battery 3011 is not connected to the coil 3012, so that the second battery 3021 is used to charge the coil 3012, and reverse charging is performed through the coil 3012. In such a reverse charging scenario, the coil 3012 is charged using the second battery 3021, and the coil 3012 may transmit wireless charging signals and power to wirelessly power other electronic devices.

When the reverse charging type includes only reverse OTG charging, the first reverse charging operation performed may be reverse charging through the interface using the first battery.

In practical applications, as shown in fig. 3, the second switch 3041 connected to the interface 3013 by the first battery 3011 may be controlled to be closed, so that the first battery 3011 is connected to the interface 3013, and the second switch 3042 connected to the interface 3013 by the second battery 3021 may be controlled to be turned off, so that the second battery 3021 is not connected to the interface 3013, so that the first battery 3011 is used to perform reverse charging through the interface 3013. In such a reverse charging scenario, the first battery 3011 is used to provide wired power out through the interface 3013.

When the reverse charging type includes reverse wireless charging and reverse OTG charging, the first reverse charging operation performed may be reverse charging through the interface using the first battery, charging the coil using the second battery, and reverse charging through the coil.

In practical applications, as shown in fig. 3, the second switch 3041 connected to the interface 3013 by the first battery 3011 may be controlled to be closed, and the second switch 3042 connected to the interface 3013 by the second battery 3021 may be controlled to be turned off, so as to use the first battery 3011 to perform reverse charging through the interface 3013. Meanwhile, the first switch 3032 connected to the coil 3012 by the second battery 3021 may be controlled to be closed, and the first switch 3031 connected to the coil 3012 by the first battery 3011 may be controlled to be turned off, so as to charge the coil 3012 by using the second battery 3021, and perform reverse charging through the coil 3012. In such a reverse charging scenario, a first battery 3011 is used to provide wired power to one electronic device via interface 3013, and a second battery 3021 is used to charge the coil 3012 and to provide wireless power to another electronic device via the coil 3012.

In an actual implementation process, the electronic device may further include a controller electrically connected to the first switch and the second switch, so as to control the turn-off and turn-on of the first switch and the second switch, thereby controlling the connection states of the first battery and the second battery with the coil through the first switch, and controlling the connection states of the first battery and the second battery with the interface through the second switch.

Because the position relation of the coil and the battery, the coil and the first battery are arranged in the first equipment main body at the same time, the second battery is arranged in the second equipment main body, the coil generates heat relatively large during reverse wireless charging, and more heat is added when the first battery is used for wireless power supply, so that the second battery can be used for reverse charging through the coil during reverse wireless charging, and the heat of the electronic equipment can be reduced.

And because the wiring distance relation of battery and interface, the interface sets up on first equipment main part, and when reverse OTG charges, the wiring of the first battery of interface distance setting in first equipment main part as well is short compared with the second battery of setting in second equipment main part, therefore, when using first battery to carry out reverse charging through the interface and carrying out reverse charging through the interface with using the second battery, its power transmission loss is less, can effectively reduce electronic equipment's heating like this.

In this embodiment, a first battery and a coil are disposed in a first device main body of an electronic device, an interface is disposed on the first device main body, a second battery is disposed in a second device main body of the electronic device, and a reverse charging type of the electronic device is obtained; executing a first reverse charging operation according to the reverse charging type; wherein the first reverse charging operation includes: in the case where the reverse charging type includes reverse wireless charging, charging the coil using the second battery and performing reverse charging through the coil; in the case where the reverse charging type includes reverse wired charging, reverse charging is performed through the interface using the first battery. Therefore, two batteries are arranged in the electronic equipment, and according to the position relation between the coil and the battery and the wiring distance relation between the battery and the interface, the second battery is used for charging the coil in reverse wireless charging, reverse charging is performed through the coil, and the first battery is used for reverse charging through the interface in reverse wired charging, so that loss can be reduced, and heating of the electronic equipment can be further reduced.

Optionally, after the step 102, the method further includes:

Acquiring a first temperature value corresponding to the first battery and a second temperature value corresponding to the second battery;

Switching the first reverse charging operation to a second reverse charging operation in the case where the first temperature value and the second temperature value satisfy a preset condition;

wherein the second reverse charging operation is different from the first reverse charging operation.

In this embodiment, the first temperature value corresponding to the first battery may be a real-time temperature value of the first battery during reverse charging, and the second temperature value corresponding to the second battery may be a real-time temperature value of the second battery during reverse charging.

During reverse charging, the temperatures of the first battery and the second battery change in real time due to the power output of the first battery and the second battery, and the heat productivity can be reduced by detecting the first temperature value and the second temperature value to perform the switching basis of the reverse charging operation.

Specifically, a first temperature value corresponding to the first battery may be detected by a first temperature sensor provided on or beside the surface of the first battery, and a second temperature value corresponding to the second battery may be detected by a second temperature sensor provided on or beside the surface of the second battery. Meanwhile, the controller can be respectively connected with the first temperature sensor and the second temperature sensor and used for acquiring a first temperature value corresponding to the first battery and a second temperature value corresponding to the second battery.

Then, whether the first battery is overheated or not may be determined based on the first temperature value, and whether the second battery is overheated or not may be determined based on the second temperature value, and in the case that it is determined that the first battery or the second battery is overheated, it may be determined that the first temperature value and the second temperature value satisfy a preset condition, at which time a reverse charging operation to be performed may be switched to a second reverse charging operation.

In this way, the temperature relationship between the first battery and the second battery can be utilized, and when the first battery or the second battery is determined to be overheated, the switching of the reverse charging operation is performed, so that the heat generation of the electronic equipment in the reverse charging process is reduced.

In the reverse charging process, the preset conditions are different from each other, and accordingly, the second reverse charging operation is also different from each other.

Optionally, the reverse charging type only includes reverse wireless charging or reverse wired charging;

And switching the first reverse charging operation to a second reverse charging operation when the first temperature value and the second temperature value satisfy a preset condition, including:

if the second temperature value is greater than a first threshold value and the first temperature value is less than the first threshold value, switching the second battery to the first battery to charge the coil and performing reverse charging through the coil;

Or if the first temperature value is greater than a first threshold value and the second temperature value is less than the first threshold value when the reverse charging type only comprises reverse wired charging, switching the first battery to the second battery, and performing reverse charging through the interface.

In this embodiment, when the reverse charging type includes only reverse wireless charging, a default reverse charging mode may be selected to perform reverse charging when the reverse wireless charging is started, where the default reverse charging mode may be that the second battery is used to charge the coil and reverse charging is performed by the coil, and accordingly, the first reverse charging operation of the default reverse charging mode is performed.

It can be appreciated that the interval time t is polled, the first temperature value corresponding to the first battery and the second temperature value corresponding to the second battery are detected by the temperature sensor, and then, based on the relationship between the first temperature value and the second temperature value and the first threshold, it can be determined whether to switch the first reverse charging operation to the second reverse charging operation.

Specifically, when the second temperature value is greater than the first threshold value and the first temperature value is less than the first threshold value, it may be indicated that the second battery that is being reversely charged is overheated at this time, and the reverse charging operation may be switched, and the second battery may be switched to the first battery to charge the coil and to be reversely charged through the coil.

In the case that the reverse charging type includes only reverse wired charging, a default reverse charging mode may be selected for reverse charging when the reverse wired charging is started, and the default reverse charging mode may be reverse charging using the first battery through the interface, and accordingly, a first reverse charging operation of the default reverse charging mode is performed.

Specifically, when the first temperature value is greater than the first threshold value and the second temperature value is less than the first threshold value, it may be indicated that the first battery that is being reversely charged is overheated, and the reverse charging operation may be switched, the first battery may be switched to the second battery, and the reverse charging may be performed through the interface.

In practical applications, the first thresholds may be the same or different, and the first thresholds for determining whether the first battery and the second battery are overheated may be the same or different, which are not particularly limited herein.

In the present embodiment, in the case where the reverse charging type includes only reverse wireless charging or reverse wired charging, by determining whether or not the battery performing reverse charging is overheated, in the case of overheating, switching of the reverse charging operation is performed to switch to another battery to perform reverse charging. Thus, the overheated battery can radiate heat, and the electronic equipment can be prevented from being overheated.

Optionally, after the first reverse charging operation is switched to the second reverse charging operation in the case that the first temperature value and the second temperature value meet the preset condition, the method further includes:

After a preset time period of reverse charging of the electronic equipment, acquiring a third temperature value corresponding to the first battery and a fourth temperature value corresponding to the second battery;

Controlling the first battery and the second battery to be simultaneously reversely charged under the condition that the third temperature value is smaller than the first threshold value and the fourth temperature value is smaller than the first threshold value;

and controlling the first battery and the second battery to be simultaneously reversely charged under the condition that the third temperature value is larger than the first threshold value and the fourth temperature value is larger than the first threshold value.

In this embodiment, after a preset period of time for the electronic device to perform reverse charging, for example, after the electronic device supplies power to other electronic devices for half an hour, in this application scenario, the two batteries may not overheat, or the two batteries may overheat. For example, when the two batteries are frequently switched to perform reverse charging, if overheat of the second battery is detected, the first battery is switched to perform reverse charging, and in the reverse charging process, overheat of the first battery is detected, heat of the second battery is not fully dissipated, overheat of the second battery is detected, and at this time, overheat of both batteries occurs.

For this application scenario, when the reverse charging type includes only reverse wireless charging or reverse wired charging, after a preset period of time, a third temperature value corresponding to the first battery and a fourth temperature value corresponding to the second battery may be obtained, where the third temperature value is smaller than a first threshold value and the fourth temperature value is also smaller than the first threshold value, it may be indicated that the reverse charging power is insufficient to overheat one battery, at this time, the first battery and the second battery may be controlled to perform reverse charging at the same time, and the power of each battery for reverse charging may be unchanged, so, under the condition that the electronic device is not overheated, the reverse charging power may be improved, and thus the charging efficiency may be improved.

When the third temperature value is greater than the first threshold value and the fourth temperature value is greater than the first threshold value, the reverse charging power can overheat any one of the electricity, and at this time, the first battery and the second battery can be controlled to be charged reversely at the same time. Meanwhile, the power of the two batteries for reverse charging can be reduced, and the total power of the reverse charging can be divided into two to act on the two batteries, namely, the total power of the batteries for reverse charging is not changed, and the power supplied by the batteries is reduced, therefore, the temperature of the battery can be reduced, and the other two batteries are simultaneously powered, so that the heat dissipation area of the battery is correspondingly increased, and the heat dissipation of the electronic equipment is faster, therefore, the temperature of the electronic equipment can be reduced, and the electronic equipment is prevented from continuously overheating.

In addition, after the electronic device performs reverse charging for a preset period of time, the device may also be polled at intervals t to obtain the temperature corresponding to the first battery and the temperature of the second battery, and when only one battery is powered, if the battery performing reverse charging is overheated, the other battery may be switched to perform power supply, so that the battery performing power supply is repeatedly switched to prevent the electronic device from overheating.

Optionally, the reverse charging type includes reverse wireless charging and reverse wired charging;

when the first temperature value is larger than a second threshold value and the second temperature value is larger than the second threshold value, adjusting power supply parameters of the first battery and the second battery during reverse charging so as to enable the first reverse charging operation to be switched to a second reverse charging operation;

or when one of the first temperature value and the second temperature value is smaller than the second threshold value, and the other of the first temperature value and the second temperature value is larger than the second threshold value, switching the second battery to the first battery to charge the coil, and carrying out reverse charging through the coil, switching the first battery to the second battery, and carrying out reverse charging through the interface.

In this embodiment, when the reverse charging type includes reverse wireless charging and reverse wired charging, a default reverse charging mode may be selected to perform reverse charging when the reverse charging is started, where the default reverse charging mode may be reverse charging using the first battery through the interface, charging the coil using the second battery, and reverse charging using the coil, and accordingly, the first reverse charging operation of the default reverse charging mode is performed.

It can be appreciated that the interval time t is polled, the first temperature value corresponding to the first battery and the second temperature value corresponding to the second battery are detected by the temperature sensor, and then, based on the relationship between the first temperature value and the second threshold, it can be determined whether to switch the first reverse charging operation to the second reverse charging operation. The first threshold value and the second threshold value may be the same or different, and are not limited herein.

Specifically, when the first temperature value is greater than the second threshold value and the second temperature value is greater than the second threshold value, it is indicated that both batteries are overheated, and the reverse charging operation needs to be switched. In this scenario, an existing reverse charging manner, that is, an existing power supply relationship, may be maintained, and power supply parameters when the first battery and the second battery are reversely charged may be adjusted, so that the first reverse charging operation is switched to the second reverse charging operation. In this way, the temperature of the two batteries is reduced by adjusting the power supply parameters, so that the electronic equipment is prevented from being overheated.

For example, the output power of the first battery and the second battery during reverse charging is reduced, that is, the two batteries are powered by the power output of the down-shift of the two batteries to perform reverse wireless charging and reverse OTG charging, so as to reduce heat generation.

For another example, the power supply time when the first battery and the second battery are reversely charged is adjusted, so that the first battery and the second battery are alternately reversely charged in time, such as polling charging, particularly reverse charging can be performed in an intermittent manner, reverse wired charging is performed only by the first battery in a first time period, reverse wireless charging is performed only by the second battery in a second time period, and the first time period and the second time period are continuous, so that heat dissipation time can be given to the battery, and overheating of the electronic device is prevented.

In the reverse charging process, when the first battery is used for reverse charging through the interface, the second battery is used for charging the coil, and reverse charging is performed through the coil, when one of the first temperature value and the second temperature value is smaller than the second threshold value, and the other of the first temperature value and the second temperature value is larger than the second threshold value, if the first temperature value is detected to be smaller than the second threshold value and the second temperature value is detected to be larger than the second threshold value, or the first temperature value is detected to be larger than the second threshold value and the second temperature value is detected to be smaller than the second threshold value, the power output requirement of one battery is large, the heat generation is large, and the power output requirement of the other battery is small, and the heat generation is small. Under the scene, the reverse charging mode of the first battery and the second battery can be switched, so that the power supply relation of the first battery and the second battery can be replaced, the second battery is used for reverse charging through the interface, the first battery is used for charging the coil, and the coil is used for reverse charging, so that the overheat of the electronic equipment can be prevented.

In addition, in the reverse charging process, when the first temperature value is smaller than the second threshold value and the second temperature value is smaller than the second threshold value, the default reverse charging mode, that is, the existing power supply relation, can be maintained, namely, the first battery is used for reverse charging through the interface, the second battery is used for charging the coil, and the coil is used for reverse charging.

Optionally, the adjusting the power supply parameters when the first battery and the second battery are reversely charged includes:

Reducing output power of the first battery and the second battery when the first battery and the second battery are reversely charged;

Or adjusting the power supply time when the first battery and the second battery are reversely charged, so that the first battery and the second battery are alternately reversely charged in time.

When the first temperature value is greater than the second threshold value and the second temperature value is greater than the second threshold value, the two batteries are overheated, the reverse charging operation needs to be switched, and specifically, the output power of the first battery and the second battery during reverse charging can be reduced, namely, the two batteries are subjected to power down and power down to output power for reverse wireless charging and reverse OTG charging, so that heat generation is reduced.
