It should be noted that the present invention uses the first battery and the second battery to supply power to the electronic device. The second battery is fixedly installed in the electronic device, and the second battery is not replaceable in normal use of the electronic device, but the first battery is not fixedly installed in the electronic device but replaceable relative to the electronic device, for example, the first battery is replaced by plugging, detaching and the like in normal use of the electronic device. In some embodiments, the electronic device is of a modular design, and the first battery forms a separate module that is connected to the electronic device by a connection cord, which can significantly reduce the size of the electronic device. In other embodiments, the electronic device is designed as a single unit, the first battery is detachably mounted to the electronic device, and the first battery can be pulled out from the electronic device through a switch, a locking structure, and the like. The manner of mounting the first battery to the electronic device is only an example, and is not limited herein.

And, when first battery electric quantity is not enough and need to be changed new first battery, for example, through pulling out first battery and change new first battery, electronic equipment accessible second battery supplies power to electronic equipment to realized not shutting down under the circumstances that does not fall the power, quick replacement first battery has promoted electronic equipment's duration.

The method for supplying power to a dual battery according to an embodiment of the present invention is described below with reference to specific embodiments.

The first embodiment is as follows:

the embodiment of the invention provides a double-battery power supply method, which comprises the following steps:

in some embodiments, if the first battery has been connected to the electronic device, controlling the first battery to supply power to the electronic device further includes: continuously detecting whether the current electric quantity of the second battery is smaller than a second preset threshold value; and if the current electric quantity of the second battery is smaller than the second preset threshold value, controlling the first battery to charge the second battery while supplying power to the electronic equipment. For example, after the electronic device is powered on, the system detects whether the first battery has been connected to the electronic device. If the first battery is not connected to the electronic equipment, the second battery supplies power to the electronic equipment, and preferably, the system prompts a user to insert the first battery; if the first battery is connected to the electronic equipment, controlling the first battery to supply power to the electronic equipment, and meanwhile, continuously detecting whether the current electric quantity of the second battery is smaller than a second preset threshold value by the system; if the current equivalent of the second battery is smaller than the second preset threshold value, which indicates that the second battery needs to be charged, the first battery is controlled to charge the second battery while supplying power to the electronic equipment, so that the situation that the electronic equipment cannot be supplied with power due to insufficient electric quantity of the second battery when the first battery is not connected to the electronic equipment is avoided; and if the current electric quantity of the second battery is greater than or equal to a second preset threshold value, the second battery does not need to be charged. Illustratively, the first battery charges the second battery to an electric quantity preset by the system.

In some embodiments, after it is detected that the first battery is connected to the electronic device, it is continuously determined whether the current electric quantity of the first battery is greater than a first preset threshold; and if the current electric quantity of the first battery is smaller than or equal to the first preset threshold value, prompting a user to charge the first battery. For example, after it is detected that the first battery is connected to the electronic device, it is continuously determined whether the current electric quantity of the first battery is greater than a first preset threshold; if the current electric quantity of the first battery is larger than a first preset threshold value, the current electric quantity of the first battery is sufficient and does not need to be charged, and the first battery continues to supply power for the electronic equipment; and if the current electric quantity of the first battery is smaller than or equal to the first preset threshold value, the current electric quantity of the first battery is insufficient, and the first battery needs to be charged, prompting a user to charge the first battery. In some embodiments, after the electronic device is powered on, the system starts to detect the electric quantity of the first battery and/or the second battery in real time; in other embodiments, after the power of the first battery is greater than the first preset threshold or after the first battery is connected to the electronic device, the system starts to detect the power of the second battery in real time, which is not limited herein.

In some embodiments, the manner of charging the first battery includes any one of the following first to third:

the first item: and charging the first battery online, and controlling the first battery to supply power to the electronic equipment while being charged.

Illustratively, the online charging of the first battery, the controlling the first battery to supply power to the electronic device while being charged further includes: continuously detecting whether the current electric quantity of the second battery is smaller than a second preset threshold value; and under the condition that the current electric quantity of the second battery is smaller than the second preset threshold value, controlling the first battery to charge the second battery while supplying power to the electronic equipment. For example, when the current electric quantity of the first battery is less than or equal to the first preset threshold, the first battery may be charged in an online manner such as an external charging line or an external mobile power source, at this time, since the first battery is still connected to the electronic device, the first battery is controlled to supply power to the electronic device while being charged, and during this period, when it is detected that the current electric quantity of the second battery is less than the second preset threshold, the first battery is controlled to supply power to the electronic device while being charged, and simultaneously, the second battery is also charged.

The second term is: the first battery is charged off line, and the second battery is controlled to supply power to the electronic equipment; for example, when the current electric quantity of the first battery is less than or equal to the first preset threshold, the first battery is pulled out/detached from the electronic device, and the first battery can be charged in an offline manner such as an external charging dock, and at this time, the second battery supplies power to the electronic device because the first battery is not connected to the electronic device.

The third item: and when the first battery is replaced, controlling a new first battery to supply power to the electronic equipment after the fact that the new first battery is connected is detected.

Illustratively, the step of replacing the first battery and controlling a new first battery to supply power to the electronic device after detecting that the new first battery is accessed further comprises: continuously detecting whether the current electric quantity of the second battery is smaller than a second preset threshold value; and under the condition that the current electric quantity of the second battery is smaller than the second preset threshold value, controlling the new first battery to charge the second battery while supplying power to the electronic equipment. For example, when the current electric quantity of the first battery is less than or equal to the first preset threshold, the first battery may be replaced with a new first battery by pulling out/detaching or the like. And controlling the second battery to supply power to the electronic equipment during the replacement of the first battery because the first battery/new first battery is not connected to the electronic equipment. And when the current electric quantity of the second battery is detected to be smaller than the second preset threshold value, the new first battery is controlled to supply power to the electronic equipment and charge the second battery. Wherein the new first battery has a higher charge than the first battery. The third item is different from the second item in that the electronic device in the second item only has the second battery, and the electronic device in the third item has the second battery and the new first battery, so that the third item is that the new first battery supplies power to the electronic device, and the second item is that the second battery supplies power to the electronic device.

The first embodiment provides that the electronic equipment is powered by the first battery when the first battery is connected into the electronic equipment, and the electronic equipment is powered by the second battery when the first battery is not connected into the electronic equipment. The first electronic is charged in three ways (online, offline, and replaced), and the second battery is charged by the first battery.

Therefore, the purpose of charging the first battery and/or the second battery is to normally supply power to the electronic device, so that the problem of system power failure caused by insufficient electric quantity of the second battery and incapability of supplying power to the electronic device when the first battery is not connected to the electronic device is solved.

Example two:

because the electronic equipment is powered by the first battery or the second battery uninterruptedly after being started, if the temperature of the first battery or the second battery is too high, the working efficiency and the service life of the battery and the normal use of the electronic equipment are affected, and therefore, the working temperature of the first battery and/or the second battery needs to be detected in real time.

In some embodiments, it is continuously detected whether the temperature of the first battery is greater than a first preset temperature threshold and/or it is continuously detected whether the temperature of the second battery is greater than a second preset temperature threshold; and if the temperature of the first battery is greater than the first preset temperature threshold and/or the temperature of the second battery is greater than the second preset temperature threshold, starting a corresponding temperature protection mechanism. The first preset temperature threshold and the second preset temperature threshold may be the same or different. The temperature protection mechanism includes, but is not limited to, stopping power supply, stopping charging, controlling the electronic device to shut down, and the like. The temperature of the first battery and/or the second battery is continuously detected, which may be after the electronic device is powered on, or after the first battery and/or the second battery starts to be charged or powered, which is not limited herein. For example, it may be possible to continuously detect only whether the temperature of the first battery is greater than a first preset temperature threshold, and not detect whether the temperature of the second battery is greater than a second preset temperature threshold; when the temperature of the first battery is greater than a first preset temperature threshold value, starting a corresponding temperature protection mechanism; for another example, it may only be continuously detected whether the temperature of the second battery is greater than the second preset temperature threshold, and it is not detected whether the temperature of the first battery is greater than the first preset temperature threshold; when the temperature of the second battery is greater than a second preset temperature threshold value, starting a corresponding temperature protection mechanism; for example, it is possible to continuously detect whether the temperature of the second battery is greater than the second preset temperature threshold while continuously detecting whether the temperature of the first battery is greater than the first preset temperature threshold. And when the temperature of the first battery is greater than a first preset temperature threshold value or when the temperature of the second battery is greater than a second preset temperature threshold value, starting a corresponding temperature protection mechanism.

Fig. 2 is a schematic flow chart of simultaneously detecting the temperatures of the first battery and the second battery according to an embodiment of the present invention. The double-battery power supply method provided by the embodiment of the invention further comprises the following steps:

step 301, the electronic device is powered on.

Step 302, continuously detecting whether the temperature of a first battery of the electronic device is greater than a first preset temperature threshold.

If the temperature of the first battery is greater than the first predetermined temperature threshold, go to step 304.

Step 303, continuously detecting whether the temperature of the second battery is greater than a second preset temperature threshold.

If the temperature of the second battery is greater than the second preset temperature threshold, step 304 is executed. At step 304, a corresponding temperature protection mechanism is initiated.

Fig. 2 shows an example in which the temperature of the first battery and the temperature of the second battery are detected at the same time, but in another embodiment of the present invention, the temperature of the first battery and the temperature of the second battery may not be detected at the same time.

In some embodiments, said initiating a respective temperature protection mechanism comprises any one of: the first item: continuously detecting whether the temperature of the second battery is greater than a second preset temperature threshold value or not during the period that the first battery charges the second battery; and when the temperature of the second battery is greater than the second preset temperature threshold value, controlling the first battery to stop charging the second battery. The second term is: continuously detecting whether the temperature of the first battery is greater than a first preset temperature threshold value or not during the period that the first battery supplies power to the electronic equipment; and when the temperature of the first battery is greater than the first preset temperature threshold value, controlling the first battery to stop supplying power to the electronic equipment or controlling a system to be shut down. The third item: continuously detecting whether the temperature of the second battery is greater than a second preset temperature threshold value or not during the period that the second battery supplies power to the electronic equipment; and when the temperature of the second battery is greater than the second preset temperature threshold value, controlling the second battery to stop supplying power to the electronic equipment or controlling a system to be shut down. Continuously detecting whether the temperature of the first battery is greater than a first preset temperature threshold value or not during online charging of the first battery; and when the temperature of the first battery is greater than the first preset temperature threshold value, controlling the first battery to stop charging.

In some embodiments, after the electronic device is powered on, the system starts to detect the temperature of the first battery and/or the second battery in real time. In other embodiments, the system begins to detect the temperature of the first battery and/or the second battery in real time after the first battery and/or the second battery begin to charge or power.

For example, during the period when the first battery charges the second battery, for example, when the current electric quantity of the second battery is smaller than a second preset threshold, the first battery charges the second battery, and if the temperature of the second battery is greater than the second preset temperature threshold, a corresponding temperature protection mechanism is started, for example, the first battery is controlled to stop charging the second battery.

For another example, during the period that the first battery supplies power to the electronic device, if the first battery is connected to the electronic device, the first battery supplies power to the electronic device, and if the temperature of the first battery is greater than the first preset temperature threshold, the corresponding temperature protection mechanism is started, for example, the first battery is controlled to stop supplying power to the electronic device or the system is controlled to shut down. For another example, during the period that the second battery supplies power to the electronic device, if the first battery is not connected to the electronic device, the second battery supplies power to the electronic device, and if the temperature of the second battery is greater than a second preset temperature threshold, a corresponding temperature protection mechanism is started, for example, the second battery is controlled to stop supplying power to the electronic device or the system is controlled to shut down.

For another example, when the first battery is charged online, if the current electric quantity of the first battery is less than or equal to a first preset threshold, the first battery is selected to be charged in an online manner such as an external charging line or a charger, and if the temperature of the first battery is greater than the first preset temperature threshold, the charging of the first battery is stopped. For example, when the first battery is charged online, and the electronic device is powered by the first battery and the second battery is charged by the first battery, it is also necessary to detect the temperature of the first battery and/or the second battery in real time, and if the real-time temperature of the first battery is greater than the first preset temperature threshold and/or the real-time temperature of the second battery is greater than the second preset temperature threshold, applying a temperature protection mechanism to the first battery and/or the second battery includes any one of stopping charging the first battery, stopping power supply to the electronic device, controlling a system to shut down, and stopping charging the second battery, which may be specifically set according to actual needs, and the present invention is not limited thereto.

The embodiment of the invention provides the temperature protection mechanism function of the double-battery power supply method, and the safety protection of the double batteries during charging or power supply of electronic equipment can be realized.

Example three:

in some special cases, such as the first battery or the second battery is overcharged or overdischarged. The overcharging means that the battery is charged continuously after reaching a full-charge state; over-discharge means that the battery continues to discharge after being normally discharged to a cut-off voltage. In either case, the life of the dual battery and the normal use of the electronic device are affected. Therefore, it is necessary to provide a protection mechanism for forcing the switching signal in the embodiments of the present invention.

Fig. 3 is a schematic flow chart of a forced handover process according to an embodiment of the present invention, as shown in fig. 3. The double-battery power supply method provided by the embodiment of the invention comprises the following steps:

step 401, the electronic device is powered on.

In step 402, if the forced switching signal is not received, step 403 is executed.

Step 403, performing the steps of the dual battery power supply method according to the first embodiment and/or the second embodiment, which are not described herein again.

In step 404, if a forced switching signal is received, step 405 is executed.

Step 405, performing corresponding control processing according to the forced switching signal.

Alternatively, the forced switching signal may be a forced switching signal set by the system according to a special situation, for example, a forced switching signal corresponding to a situation that the first battery or the second battery is overcharged or overdischarged, or may be a forced switching signal manually selected, for example, a forced switching signal corresponding to a situation that a user of the electronic device forcibly selects the first battery or the second battery to supply power, which is not limited in the embodiment of the present invention.

In some embodiments, after the first battery is in an over-discharge condition (for example, the voltage of the first battery is 0V), or after the user of the electronic device selects the second battery to supply power, even if the first battery is connected to the electronic device or the second battery is in the over-discharge condition, the system receives a forced switching signal for forcibly switching the second battery to supply power, and the system controls the second battery to supply power to the electronic device; during, if the current electric quantity of second battery is less than when the second presets the threshold value or the second battery is in the overdischarge condition, can directly charge the second battery through online mode such as external charging wire or treasured that charges. In other embodiments, after the second battery is in an over-discharge condition (for example, the voltage of the second battery is 0V), or after the user of the electronic device selects the first battery to supply power, even if the first battery is not connected to the electronic device or the first battery is in an over-discharge state, the system receives a forced switching signal for forcibly switching the first battery to supply power, and the system controls the first battery to supply power to the electronic device; meanwhile, if the current electric quantity of the first battery is smaller than a first preset threshold value or the first battery is in an over-discharge state, the first battery can be charged in an online mode such as an external charging wire or a charger; furthermore, when the current electric quantity of the second battery is smaller than a second preset threshold value during the period that the first battery supplies power to the electronic device, the first battery is controlled to charge the second battery while supplying power to the electronic device.

Therefore, the forced switching protection mechanism provided by the third embodiment considers the special situations (such as overcharge, overdischarge, and the like) encountered by the first battery and the second battery during the operation and the situation of manual selection operation by the user, which is beneficial to prolonging the service lives of the first battery and the second battery and the normal use of the electronic device.

Example four:

OTG (On-The-Go) is a technology developed in recent years, and is mainly applied to connection between different devices or mobile devices to exchange data. The electronic equipment provided by the embodiment of the invention has an OTG function. Therefore, after the electronic device starts the OTG function, the first battery according to the embodiment of the present invention may be used to supply power to the OTG device.

Fig. 4 is a schematic flowchart of the power supply to the OTG device according to the embodiment of the present invention, as described in fig. 4. The double-battery power supply method of the embodiment of the invention further comprises the following steps:

step 501, the electronic device is powered on.

Step 502, detecting whether an OTG device is inserted.

If an OTG device is plugged in, step 503 is executed.

And step 503, controlling the first battery to supply power to the electronic device and also supply power to the OTG device.

As can be seen from fig. 5, the first battery 601 is used for supplying power to the OTG device through the OTG power supply unit 603, for supplying power to the electronic device through the battery switching unit 607, and for charging the second battery 602 through the charging management unit 608. The second battery 602 is used to supply power to the electronic device through the battery switching unit 607. The charging management unit 608 is used for performing charging management on the second battery 602. The power management unit 610 is configured to detect temperatures of the second battery 602 and the first battery 601, and detect power levels of the first battery 601 and the second battery 602 in real time through the first battery power detection unit 604 and the second battery power detection unit 609.

The CPU control unit 611 is configured to detect whether the first battery is connected to the electronic device through the first battery presence detection unit 606. The CPU control unit 611 is used to perform power supply battery switching by controlling the battery switching unit 607. The CPU control unit 611 is configured to control the charging management unit 608 to perform charging management on the second battery 602. The CPU control unit 611 is configured to perform charger access detection for the external charger access unit 613. The CPU control unit 611 is configured to perform charger input conduction control on the charging control unit 612.

The first battery presence detection unit 606, the battery switching unit 607, the external charger access unit 613, the charging management unit 608, the OTG power supply unit 603, and the like in fig. 5 will be described in detail below with reference to fig. 6 to 11.

Illustratively, the circuit of the first battery presence detecting unit 606 is shown in fig. 6, and the first battery presence detecting unit 606 is configured to detect whether the first battery has been connected, for example, whether the first battery is in place. If the first battery is connected, the enable generator in the first battery presence detection unit 606 outputs an enable signal to the high-low level switching circuit, which causes the input level of the GPIO1 interface of the CPU control unit 611 to change, so that the CPU control unit 611 can detect whether the first battery is connected.

It should be noted that the GPIO1 interface is only an example, and may also be a GPIO2 interface or other interfaces, which are specifically set according to actual circuit requirements, and the present invention is not limited to the GPIO1 interface.

Illustratively, if the embodiment of the present invention does not consider the case of forced switching described in the third embodiment, the circuit of the battery switching unit 607 in fig. 5 for performing the first and second battery switching is shown in fig. 7:

the battery switching unit 607 includes an enable generator, a switching circuit, a first switch, and a second switch. If the first battery 601 has been connected to the electronic device, the first battery 601 drives the enable generator in the battery switching unit 607, the enable generator outputs a signal to the switching circuit, and the switching circuit outputs the enable required for turning on the first switch of the first battery to supply power to the electronic device, so as to control the first battery 601 to supply power to the electronic device. If the first battery 601 is not connected to the electronic device, the switching circuit outputs the enable required for turning on the second switch for supplying power to the electronic device by the second battery, and controls the second battery 602 to supply power to the electronic device.

Exemplarily, if the embodiment of the present invention considers the case of forced switching shown in the third embodiment, the circuit of the battery switching unit 607 in fig. 5 for performing the first and second battery switching is shown in fig. 8:

the battery switching unit 607 includes an enable generator, a first stage comparison circuit, a second stage comparison circuit, a first high-low level switching circuit, a second high-low level switching circuit, a third high-low level switching circuit, a first switch, and a second switch. The first battery 601 drives the enable generator, the enable generator outputs a signal to the first stage of comparison circuit, and the CPU control unit 611 sends a signal to the first high-low level switching circuit in the battery switching unit 607 through the GPIO2 interface, the signal of the GPIO2 interface does not change with the connection or the disconnection of the first battery, and the first high-low level switching circuit also outputs a signal to the first stage of comparison circuit for comparison. The first-stage comparison circuit outputs a signal to the second-stage comparison circuit after comparison, the second-stage comparison circuit compares the signal with a signal output by a GPIO3 interface of the CPU control unit 611, the signal output by the GPIO3 interface cannot change along with the connection or the extraction of the first battery 601, and the second-stage comparison circuit outputs a signal to the switching circuit after comparison. The second high-low level switching circuit and the third high-low level switching circuit are used to satisfy logic switching requirements (such as level amplitude or high-low requirements), and if one or more high-low level switching circuits can satisfy the logic switching requirements, one or more high-low level switching circuits may also be used, where the number of the high-low level switching circuits is not limited herein.

Illustratively, the GPIO2 interface may output a forcing signal for forcing a switch to a second battery by which the electronic device is powered. When the second battery supplies power to the electronic device through the forced switching signal, if the current electric quantity of the second battery is smaller than the second preset threshold value or the second battery is in an over-discharge state, the second battery can be directly charged through an external charging wire or an external mobile power supply, and the second battery does not need to be charged by the first battery like the embodiment.

It should be noted that the forcing signal output through the GPIO2 interface is used to force the second battery to be switched to supply power to the electronic device, even if the second battery is in an overdischarged state, or even if the first battery is connected to the electronic device (whether the first battery is overdischarged or not), the forcing signal can be forced to be switched to the second battery.

For example, the GPIO3 interface may output a forcing signal for forcing the switching to the first battery to supply power to the electronic device from the first battery, and the first battery may be forced to be switched to the first battery even if the first battery is not connected to the electronic device, or the first battery is in an over-discharge state, or the first battery cannot identify whether the first battery is connected to the electronic device by the presence detection unit 606. When the first battery supplies power to the electronic equipment through the forced switching signal, if the current electric quantity of the first battery is smaller than a first preset threshold value or the first battery is in an over-discharge state, the first battery is directly charged through an external charging line or an external mobile power supply, and further, when the first battery supplies power to the electronic equipment through the forced switching signal and the current electric quantity of the second battery is smaller than a second preset threshold value, the first battery is controlled to charge the second battery while supplying power to the electronic equipment.

Illustratively, if neither the GPIO2 interface nor the GPIO3 interface outputs the forcing signal, when the first battery is connected to the electronic device, the switching circuit outputs an enable signal required to turn on the switch for powering the electronic device by the first battery, and the electronic device is powered by the first battery at this time; when the first battery is not connected with the electronic equipment, the switching circuit outputs an enabling signal required by a switch for conducting the second battery to supply power to the electronic equipment, and at the moment, the second battery supplies power to the electronic equipment.

It should be noted that the interfaces GPIO2 and GPIO3 are only examples, and may be other interfaces, which are specifically set according to actual circuit requirements, and the present invention is not limited to the interfaces GPIO2 and GPIO 3.

Illustratively, the power management unit 610 shown in fig. 5 acquires the power of the first battery 601 in real time through the first battery power detection unit 604. If the power management unit 610 detects that the electric quantity of the first battery 601 is smaller than the first preset threshold, it prompts the user to charge the first battery 601. If the first battery is replaced by a new first battery, the CPU control unit 611 obtains that the first battery is already pulled out through the first battery presence detection unit 606, and the CPU control unit 611 controls the battery switching unit 607 to switch the power supply of the electronic device to the power supply of the second battery 602, so as to ensure that the electronic device is not powered off and is not powered down during the replacement of the first battery (as shown in fig. 7). If the first battery 601 is charged by an external charging line or an external mobile power source, the CPU control unit may detect whether the charger is connected through the external charger access unit 613, and the process of charging through the external charger access unit 613 in fig. 5 is shown in fig. 9.

In fig. 9, when the charger is connected, the external charger connection unit 613 sends a signal to the GPIO4 interface of the CPU control unit 611, and the GPIO5 interface of the CPU control unit 611 controls the high-low level switching circuit to output an enable signal required to turn on the switch for charging the external charger to the charging control unit 612, and then charges the currently used battery (the first battery 601 or the second battery 602) through the power management unit 610.

The power management unit 610 acquires the power of the second battery 602 in real time through the second battery power detection unit 609. In some embodiments, after the electronic device is powered on, the power management unit 610 shown in fig. 5 may detect the power of the second battery in real time (regardless of whether the power of the first battery is sufficient or not). If the second battery 602 needs to be charged, in the absence of the forced switching signal, the CPU control unit 611 controls the charging management unit 608 to charge the second battery 602 through the charging management unit 608 by the first battery 601 (as shown in fig. 10).

It should be noted that the interfaces GPIO4 and GPIO5 are only examples, and may be other interfaces, which are specifically set according to actual circuit requirements, and the present invention is not limited to the interfaces GPIO4 and GPIO 5.

In fig. 10, the GPIO6 interface of the CPU control unit 611 is electrically connected to the enable terminal of the step-up DCDC converter (which represents a device that converts a dc power supply of a certain voltage level into a dc power supply of another voltage level) to control the enable of the step-up DCDC converter through the GPIO6 interface; the GPIO7 interface of the CPU control unit 611 is electrically connected to the enable terminal of the charging management unit 608, and is configured to output an enable signal to the charging management unit 608. The first battery 601 is electrically connected to an input terminal of the step-up DCDC converter. The output terminal of the boost DCDC converter is electrically connected to the input terminal of the charge management unit 608 to output a voltage signal for charging the second battery 602. When the GPIO7 interface of the CPU control unit 611 outputs an enable signal to the charge management unit 608, the first battery 601 starts charging the second battery 602. After acquiring the electric quantity of the second battery 602, the power management unit 610 notifies the CPU control unit 611, and the CPU control unit 611 controls the electric quantity charged by the second battery 602 through the GPIO6 interface and the GPIO7 interface.

It should be noted that the interfaces GPIO6 and GPIO7 are only examples, and may be other interfaces, which are specifically set according to actual circuit requirements, and the present invention is not limited to the interfaces GPIO6 and GPIO 7. For example, the power management unit 610 shown in fig. 5 acquires the temperature of the first battery 601 in real time through the first battery temperature detection unit 605, and the power management unit 610 may also acquire the temperature of the second battery 602 in real time through the second battery temperature detection unit 614. The temperature protection mechanism as described in the second embodiment above is then adopted according to the current temperatures of the first battery 601 and the second battery 602.

Exemplarily, a power supply flow of the OTG power supply unit 603 illustrated in fig. 5 is illustrated in fig. 11. After the electronic device starts the OTG function, the OTG power supply unit 603 supplies power to the OTG device, and the first battery 601 directly supplies power to the OTG power supply unit 603.

Fig. 11 shows that the first battery 601 is electrically connected to an input terminal of the switch, a CPIO8 interface of the CPU control unit 611 is electrically connected to an enable terminal of the high-low level switching circuit and an enable terminal of the boost DCDC converter, respectively, an output terminal of the high-low level switching circuit is connected to the enable terminal of the switch, an input terminal of the boost DCDC converter is connected to an output terminal of the switch, and an output terminal of the boost DCDC converter is electrically connected to the OTG device.

When detecting that an OTG device is connected, the CPU control unit 611 outputs an enable signal to the high-low level switching circuit and the boost DCDC converter through the GPIO8 interface, the high-low level switching circuit outputs the enable signal to the on-switch of the first battery, and outputs the voltage of the first battery to the input end of the boost DCDC converter through the output end of the switch, and the boost DCDC converter boosts the voltage to a preset voltage value (for example, 5V) and outputs the voltage to the OTG device through the electronic device interface.

It should be noted that the GPIO8 interface is only an example, and may be other interfaces, which are specifically set according to actual circuit requirements, and the present invention is not limited to the GPIO8 interface.
