Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a flowchart illustrating an electric energy management method according to an embodiment of the present disclosure, as shown in fig. 1, including the following steps:

s11, determining the working state between a first battery and a second battery in the equipment, wherein the first battery is connected with a main control module in the equipment and supplies power to the main control module; the second battery is connected with the display module in the equipment and supplies power to the display module; wherein the operating state comprises: the combined state of the electric quantity can be balanced between the first battery and the second battery; and a separated state in which the electric quantities of the first battery and the second battery are not balanced with each other;

s12, determining a battery management strategy according to the working state;

and S13, controlling the charging and discharging of the first battery and/or the second battery according to the battery management strategy.

In an embodiment of the present disclosure, an apparatus includes: a mobile phone, a tablet computer, or a wearable device, etc. The equipment comprises a main control module and a display module, wherein the main control module and the display module can be combined together to form an integral structure; the main control module and the display module can be used separately, for example, the user can hold the display module by hand and put the main control module in a pocket. Based on the design of the separable and combinable structure, the main control module and the display module are respectively powered by batteries. The first battery for supplying power to the main control module is positioned in the main control module, and the second battery for supplying power to the display module is positioned in the display module.

It should be noted that, in an embodiment, the first battery for supplying power to the main control module and the second battery for supplying power to the display module may be provided with a battery management module inside, and the battery management module is configured to monitor state information of the battery, such as voltage, current, electric quantity, charging state, overcurrent, and overvoltage, and provide protection against overcharge, overdischarge, overvoltage, overcurrent, and the like, so as to implement power supply safety of the main control module or the display module.

In another implementation, the main control module and the display module may respectively include a battery management module, but the battery management module is located outside the first battery and the second battery.

In addition, in the embodiment of the present disclosure, the main control module may include a host computing module (central processing Unit), a charging management module, a memory, and the like, and is mainly responsible for functions such as data computing, charging management, data storage, and the like, and the display module may include a Micro Controller Unit (MCU), a display module, and the like, and is mainly responsible for functions such as display, communication, and partial data processing. By separating functions such as display and the like from functions such as host operation and the like, the main control module can increase the endurance of the equipment in a mode of increasing the weight of the battery; meanwhile, the display module has less trouble of a large-capacity battery, and light and thin hand feeling can be realized.

It should be noted that, in the embodiment of the disclosure, since the main control module is mainly responsible for most of data operations and the like, and the display module is mainly responsible for functions such as displaying and the like, the rated capacity of the first battery supplying power to the main control module can be larger than the rated capacity of the second battery supplying power to the display module.

In some embodiments, for large-screen display, the power consumption of the display module in unit time may be greater than the power consumption of the main control module in unit time, and at this time, the rated capacity of the second battery is greater than the rated capacity of the first battery.

In summary, in the embodiment of the present application, the magnitude relationship between the rated capacities of the first battery and the second battery is positively correlated to the power consumption of the main control module and the display module in unit time.

Furthermore, in some embodiments, the main control module is responsible for data transceiving, data processing and/or providing basic input and output of a user, and the functions realized by the main control module are more basic and richer than those realized by the display module, and a first battery for supplying power to the main control module can be set as a main battery, and a second battery for supplying power to the display module is set as a slave battery. In some special cases, the master battery has a higher priority and/or a better performance than the slave battery. For example, the rated capacity of the first battery is larger than the rated capacity of the second battery. For another example, under the state that two batteries are all underpowered and the condition that does not have the external power supply, for the continuous standby of master control module, under the condition of master control module and display module combination, can be according to the priority, all switch to the power supply to master control module with first battery and second battery to the disconnection is to the power supply of display module.

Of course, in other embodiments, the master battery and the slave battery may not be distinguished. If the connection relation between the main battery and the slave battery and the connection relation between the main control module and the display module can be switched, when the equipment is started or enters an activated state, the current high residual capacity is set as the first battery, and the current low residual capacity is set as the second battery if the main control module and the display module are combined.

Of course, this is merely an example and the specific implementation is not limited thereto.

In the embodiment of the disclosure, based on the separable and combinable structural design of the main control module and the display module, the first battery for supplying power to the main control module and the second battery for supplying power to the display module may have different working states. For example, when the main control module and the display module are physically separated, the first battery and the second battery are not affected by each other, and can work in a separation state with mutually unbalanced electric quantity, and the endurance time of the main control module and the display module can be different in the separation state; and when the main control module and the display module are physically combined to form a whole for use, the first battery and the second battery can work in a combined state of equalizing electric quantity based on the control of the main control module, and the endurance time of the main control module and the display module can be the same in the combined state.

Therefore, in step S11, the device may determine the operating states of the first battery and the second battery according to the connection relationship (physically separated or combined) between the main control module and the display module.

It should be noted that, in the embodiment of the present disclosure, the physical separation means that the main control module and the display module are not connected through a tangible medium, and the physical combination means that the main control module and the display module are connected by using a tangible medium. When master control module and display module assembly physics combination, master control module and display module assembly can utilize the wired communication module that each included to carry out wired communication based on tangible medium.

For example, the main control module and the display module may be connected through a data interface and a data connection line. The data connection line may be a Universal Serial Bus (USB) connection line, a C-type USB data line having a high transmission speed and supporting double-sided insertion, or a high-speed multifunctional Lightning (Lightning) data line. The main control module and the display module can select corresponding data connecting lines according to the requirements of the equipment and the supported interface types.

For another example, the physical combination of the main control module and the display module may be connected through a magnetic interface, for example, through a magnetic spring contact connection, or through a metal patch connection.

In addition, in the embodiment of the disclosure, the main control module and the display module may further include a wireless communication module, respectively, when the main control module and the display module are physically separated, data communication between the main control module and the display module is performed by using the wireless communication module, and the wireless communication mode is to transmit information by using electromagnetic waves and the like. For example, the main control module and the display module include modules such as a bluetooth module, a Wireless Fidelity (Wi-Fi), a ZigBee (ZigBee) module or an infrared module, so that Wireless communication connection can be performed in a manner supported by the modules.

In the embodiment of the disclosure, after the communication connection is established between the main control module and the display module, the wireless communication connection between the main control module and the display module is disconnected. When the master control module and the display module are disconnected in wired communication, namely, the physical combination is disconnected, the master control module and the display module are automatically switched to be in wireless communication.

In step S12, the device determines a battery management strategy according to the operating states of the first and second batteries, so as to control the charging and discharging of the first and/or second batteries according to the battery management strategy in step S13.

It should be noted that, in the embodiment of the present disclosure, a charging management module may be further included in the main control module, the charging management module may be connected to an external power supply device, and a Central Processing Unit (CPU) of the main control module controls the charging management module to manage charging and discharging of the first battery and/or the second battery based on the determined battery management policy.

In the embodiment of the present disclosure, the battery management policy is, for example, to balance the electric quantity by using the mutual charging and discharging of the first battery and the second battery when the first battery and the second battery operate in a combined state that the electric quantity is balanced, or to prompt that the first battery and/or the second battery are charged by using an external charging device. For another example, the battery management policy is to prompt the first battery and the second battery to change the operating state and/or prompt charging by an external charging device when the first battery and the second battery operate in a separated state with mutually unbalanced electric quantities.

Fig. 2 is a diagram illustrating a structure of a device according to an embodiment of the present disclosure, where as shown in fig. 2, the device includes a master battery (a first battery) and a slave battery (a second battery), and both the master battery and the slave battery include a battery management module therein. The main battery provides the current state information of the first battery power supply to a host computer operation module (CPU) in the main control module through an internal battery management module, so that the host computer operation module can perform corresponding control according to the state information, for example, control over-temperature protection, prompt that the electric quantity is insufficient and external charging equipment needs to be connected, and the like; in addition, the host computer operation module also controls the wireless communication module and the charging management module in the main control module.

As shown in fig. 2, the slave battery provides the current state information of the second battery power supply to the micro control module in the display module through the internal battery management module, so that the micro control module performs corresponding control according to the state information; in addition, the micro control module also controls the wireless communication module in the display module. The main control module and the display module can perform information interaction based on respective wireless communication modules.

It should be noted that the state information provided by the main battery to the host computer operation module at least includes the electric quantity of the main battery; the status information provided from the battery to the micro control module includes at least the charge level of the battery.

As described above, the main operation module of the main control module controls the charging management module to manage charging and discharging of the first battery and/or the second battery based on the determined battery management policy. For example, after the micro control module of the display module obtains the state information of the slave battery, the state information of the slave battery is sent to the main operation module of the main control module through the wireless communication module, the main operation module determines a battery management strategy according to the state information of the main battery and the state information of the slave battery received from the display module, and controls the charging management module to distribute the electric energy obtained from the external charging module to the first battery and/or the second battery according to the battery management strategy. For another example, the main operation module determines a battery management policy according to the state information of the main battery and the state information of the slave battery received from the display module, and controls the charging management module to charge the first battery to the second battery.

It is understood that, in the embodiment of the present disclosure, the battery management strategy is determined according to the operating states of the first battery and the second battery, and the charging and discharging of the first battery and/or the second battery are controlled based on the battery management strategy, and the duration of the first battery and/or the second battery can be increased reasonably through targeted management based on the current operating state. Because equipment when using, needs main control module and display module to be in electrified state simultaneously, therefore it is long during through the duration that increases first battery and/or second battery, can also promote the usable of equipment for a long time to promote user's use and experience. In addition, the first battery or the second battery can also be discharged so as to charge batteries except for the dischargeable batteries, thereby having convenience in use.

In one embodiment, the determining a battery management policy according to the operating state includes:

In this embodiment, when the first battery and the second battery are operated in the combined state, it is determined to adopt a first policy, which includes charge direction control and/or charge amount distribution.

The first policy includes: a charging strategy determined according to rated capacities or actual capacities of the first and second batteries, for example, a charge-discharge strategy in which charge distribution is performed in inverse proportion to the actual capacities.

Under the first strategy, the device can control the external power supply device to charge the first battery and/or the second battery according to whether the respective electric quantities of the first battery and the second battery are saturated or not, or charge the first battery and the second battery according to the electric quantity proportion when the first battery and the second battery are charged by the external power supply device; for another example, under the first strategy, the first battery is utilized to charge the second battery, and so on.

When the charging and discharging management is carried out based on the first strategy, whether external power supply equipment is connected or not can be combined to further distinguish management, so that more detailed control is realized.

It should be noted that, in the embodiment of the present disclosure, the external power supply device may be a power supply device supporting wired charging and/or wireless charging. For example, the external power supply device can supply power to the device after being connected with the interface provided by the charging management module in the device through the USB interface and the C-type USB interface; or, the external power supply device can realize wireless charging through the charging coil and the charging coil interaction signal in the device.

In one embodiment, the controlling the charging and discharging of the first battery and/or the second battery according to the first policy and whether an external power supply device is connected to the device includes:

In this embodiment, the under-charged state refers to a state in which the charge of the battery is not saturated, and the unsaturated state refers to a state in which the charge of the battery is less than the maximum charge of the battery. It should be noted that if the (first/second) battery is already at its maximum capacity, the battery will not be charged when the external power supply device is connected. When the equipment is connected with external power supply equipment and the electric quantity of the first battery and the electric quantity of the second battery are both in an undervoltage state, the charging electric quantity of the first battery and the charging electric quantity of the second battery are inversely proportionally distributed according to the electric quantity proportion between the first battery and the second battery.

For example, if the charge of the first battery can last for 3 hours and the charge of the second battery can last for 1 hour, the ratio of the charges between the first battery and the second battery is 3:1, and if the charges of the first battery and the second battery are inversely proportionally distributed, the charges of the first battery and the second battery can be distributed according to the ratio of 1: 3.

Specifically, the device may control the charging amount of electricity distributed to the first battery and the second battery by the charging management module through a CPU of the main control module. For example, the CPU of the main control module controls the charging current ratio of the charging management module to the first battery and the second battery to be 1: 3.

It can be understood that if the first battery and the second battery work in a combined state and the equipment is connected with the external power supply equipment, and the electric quantity of the first battery and the electric quantity of the second battery are both in an under-power state, according to the electric quantity proportion between the first battery and the second battery, the charging electric quantity of the first battery and the second battery is distributed in an inverse proportion, the consistency of the endurance time of the main control module and the display module can be improved, the service life of the equipment can be prolonged, and the use experience of a user is improved.

In this embodiment, if the device is not connected to an external power supply device, the device may determine whether the power ratio between the first battery and the second battery exceeds a preset ratio value, where the preset ratio value is the determined power ratio between the first battery and the second battery when the power of the first battery and the second battery can satisfy the condition that the duration time of the first battery is consistent with the duration time of the second battery (the difference between the duration time of the first battery and the duration time of the second battery is within the range of the difference). It should be noted that, there is a corresponding relationship between the electric quantity of the first battery and the duration of the first battery, and there is also a corresponding relationship between the electric quantity of the second battery and the duration of the second battery.

If the electric quantity ratio between the first battery and the second battery exceeds a preset ratio value, the fact that the power supply endurance time of the main control module based on the first battery is longer than the endurance time of the display module is shown. At the moment, the first battery can be used for charging the second battery so as to improve the consistency of the endurance time of the main control module and the display module, thereby prolonging the service time of the equipment.

Of course, in the embodiment of the disclosure, if the electric quantity ratio between the first battery and the second battery is smaller than the preset ratio value, that is, when the cruising duration of the power supply of the host module based on the first battery is smaller than the cruising duration of the display module, the second battery can be used for charging the first battery, so as to prolong the service life of the device.

It can be understood that, in the embodiment of the present disclosure, when the first battery and the second battery operate in the combined state, when the device is not connected to the external power supply device, the first battery and the second battery are charged and discharged mutually to balance the electric quantity, so that the convenience of use is provided, and the usable time of the device can be prolonged.

In this embodiment, if the device is connected to an external power supply device, the device may determine a to-be-charged battery in an underrun state of the first battery and the second battery, for example, if the first battery is in the underrun state and the electric quantity of the second battery is saturated, the first battery is the to-be-charged battery; and if the second battery is in an underpower state and the electric quantity of the first battery is saturated, the second battery is the battery to be charged. At the moment, the device controls the charging management module to charge the battery to be charged by using the external power supply device through the CPU of the main control module.

Of course, in the embodiment of the present disclosure, both the first battery and the second battery may be in an underpower state, and at this time, the device may also use the external power supply device to charge the battery to be charged, which is both the first battery and the second battery.

It can be understood that if the first battery and the second battery work in a combined state and the equipment is connected with the external power supply equipment, and the electric quantity of the first battery and the electric quantity of the second battery are both in an underpower state, the external power supply equipment is utilized to charge the rechargeable battery, so that the service life of the equipment can be prolonged, and the use experience of a user is improved.

In this embodiment, when the first battery and the second battery are operated in the separated state, it is determined to adopt a second policy, which includes: and outputting an under-power state prompt to prompt a charging and discharging strategy for charging.

It should be noted that, in this embodiment, the device gives a charging prompt when the first battery and/or the second battery enters an under-charged state. The power-off state refers to a state that the electric quantity is lower than a preset electric quantity threshold value, and the main control module or the display module can possibly enter the power-off state quickly when the electric quantity is lower than the preset electric quantity threshold value. In this implementation, the charging alert includes at least one of:

prompting that external power supply equipment needs to be connected;

the main control module and the display module are prompted to be physically combined.

In the embodiment of the disclosure, if the external power supply equipment needs to be connected, the first battery and/or the second battery can be charged by using the external power supply equipment; if the main control module and the display module are prompted to be physically combined, after the main control module and the display module are physically combined, when the equipment is connected with external power supply equipment, the first battery and/or the second battery can be charged by the external power supply equipment; when the device is not connected with the external power supply device, the first battery can be used for charging the second battery, or the second battery can be used for charging the first battery.

It can be understood that, in this embodiment, the battery management strategy based on the charging prompt enables the charging and discharging of the first battery and/or the second battery to be controlled in real time according to the user operation aiming at the charging prompt, and has the characteristic of intelligence.

It should be noted that, in the embodiment of the present disclosure, if the main control module is physically separated from the display module, when the device is connected to the external power supply device through the charging control module of the main control module, the charging device can only charge the main control module. If the display module needs to be charged, besides prompting the physical combination of the main control module and the display module and charging based on the battery management strategy after the physical combination, in another embodiment, a charging control module can also be arranged in the display module to be connected with external power supply equipment for charging.

In one embodiment, the outputting a charging prompt when the first battery and/or the second battery enters an under-charged state according to the second policy includes:

and/or the presence of a gas in the gas,

In this embodiment, the device may determine whether the electric quantities of the first battery and the second battery are less than the electric quantity threshold corresponding to the power shortage state, and output a prompt correspondingly according to the electric quantity states of the first battery and the second battery.

For example, according to the device structure example shown in fig. 2, the main operation module of the main control module obtains the current state information of power supply of the first battery from the battery management module inside the first battery, analyzes and determines whether the electric quantity of the first battery is smaller than the corresponding electric quantity threshold value in the first battery power-down state, and outputs a first prompt prompting to charge the first battery if the first battery is in the power-down state. The device can control the external power supply device to charge the first battery based on the operation that the main control module is connected with the external power supply device by a user; or the device controls the second battery to charge the first battery when determining that the second battery is not in an under-power state based on the operation of the main control module and the display module which are physically combined by the user.

After the main operation module of the main control module receives the state information of the second battery from the display module based on the wireless communication module, whether the electric quantity of the second battery is smaller than a corresponding electric quantity threshold value under the power-down state of the second battery is analyzed and determined, and if the second battery is in the power-down state, a second prompt for prompting to charge the second battery is output. Based on the second prompt, the device may control the first battery to charge the second battery when determining that the first battery is not in an under-power state based on an operation of a user physically combining the main control module and the display module; alternatively, the device may charge the second battery through the external power supply device connected to the display module based on an operation of the user connecting the display module to the external power supply device other than the main control module.

When the electric quantity of the first battery and the electric quantity of the second battery are both smaller than the electric quantity threshold value corresponding to the respective under-power state, the prompt that the first battery and the second battery are both required to be charged can be output. Under the prompt, in one embodiment, the device may be an external power supply device that is based on the prompt that the main control module and the display module need to be physically combined and that the main control module is connected, and the first battery and the second battery are charged simultaneously through the external power supply device. In another embodiment, the main control module and the display module may be charged based on external power supply devices respectively connected to the main control module and the display module.

It can be understood that, in this embodiment, a prompt for charging the first battery and/or the second battery is output according to the power conditions of the first battery and the second battery, so that a user can conveniently perform a targeted operation based on different prompts, and the device can perform corresponding charging management according to different operations of the user, thereby improving the accuracy of power management in the device.

In this embodiment, if one of the first battery and the second battery is in an underrun state and the other one of the first battery and the second battery is in a saturated state, a third prompt is output, where the third prompt may prompt that the main control module and the display module need to be physically combined, so that the device can control the battery in the saturated state among the first battery and the second battery to charge the battery in the underrun state among the first battery and the second battery.

For example, if the first battery is in a saturated state and the second battery is in an undervoltage state, the first battery can be used for charging the second battery based on the physical combination of the main control module and the display module; if the first battery is in an undervoltage state and the second battery is in a saturated state, the second battery can be used for charging the first battery based on the physical combination of the main control module and the display module.

It can be understood that, in this embodiment, if the first battery and the second battery work in the separated state, when one of the first battery and the second battery is in the saturated state and the other is in the undervoltage state, the main control module and the display module are prompted to be physically combined, so that the device can balance the electric quantity by utilizing the mutual charging and discharging of the first battery and the second battery based on the operation of the user to physically combine the main control module and the display module, the use convenience is realized, and the usable time of the device can be prolonged.

Fig. 3 is a flowchart illustrating an example of a flow of an electric energy management method according to an embodiment of the present disclosure, and as shown in fig. 3, the electric energy management method includes the following steps:

s101, detecting whether the equipment is in a combined state or not, and if so, executing a step S102; if not, go to step S111.

In this embodiment, the device detects whether the device is in the combined state, which means that whether the first battery and the second battery operate in the combined state is detected. As mentioned above, the combination status is the working status of the first battery and the second battery when the main control module and the display module are physically combined to form a whole for use.

S102, if the combination state is achieved, whether an external power supply exists is detected, and if the combination state is achieved, the step S105 is executed; if not, go to step S103.

In the implementation, whether an external power supply exists is detected, namely whether the master control module is connected with an external power supply device is detected.

S103, if the external power supply is not connected, determining whether the ratio of the electric quantity of the slave battery to the electric quantity of the master battery is larger than a set value, if so, returning to execute the step S101; if not, go to step S104.

In this embodiment, determining whether the ratio of the electric quantity of the slave battery (second battery) to the electric quantity of the master battery (first battery) is greater than a set value corresponds to determining whether the ratio of the electric quantities between the first battery and the second battery exceeds a preset ratio value. If the electric quantity ratio between the first battery and the second battery exceeds a preset ratio value, that is, the electric quantity ratio between the slave battery and the master battery is smaller than a set value, it indicates that the second battery needs to be charged, and at this time, step S104 is executed; otherwise, the process returns to step S101.

And S104, controlling the master battery to charge the slave battery by the device.

It should be noted that, in the embodiment of the present disclosure, after the device controls the main battery to charge the slave battery, it is continuously detected whether the first battery and the second battery are in the combined state.

S105, if the external power supply is connected, determining whether the main battery is fully charged, and if not, executing a step S106; if yes, go to step S109.

In this embodiment, determining whether the main battery is fully charged refers to determining whether the charge amount of the main battery is saturated. When the main battery charge is saturated or unsaturated, step S106 or S109 is performed to determine whether the sub battery charge is saturated.

S106, determining whether the slave battery is fully charged, and if so, executing a step S107; if not, go to step S108.

In this embodiment, determining whether the slave battery is fully charged refers to determining whether the amount of charge of the slave battery is saturated.

And S107, if the slave battery is fully charged, the external power supply charges the master battery.

In this embodiment, when the main battery is not saturated, but the slave battery is saturated, the external power supply is controlled to charge only the main battery.

And S108, if the slave battery is not fully charged, the external power supply charges the master battery and the slave battery at the same time, and the charging current is distributed in proportion according to the electric quantity ratio.

In the embodiment, when the main battery and the slave battery are not fully charged and the device is connected with the external power supply, the external power supply is used for simultaneously charging the main battery and the slave battery, and the charging current is distributed in proportion according to the electric quantity ratio. That is, the amounts of charge to the first battery and the second battery are inversely proportionally distributed according to the amount of charge ratio between the first battery and the second battery.

After the device controls the external power supply to proportionally charge the main battery and the auxiliary battery, whether the first battery and the second battery are in a combined state or not can be continuously detected.

And S109, determining whether the slave battery is fully charged, and if not, executing the step S110.

In this embodiment, if the master battery is fully charged, it is further determined whether the slave battery is fully charged, so that the device determines an object to be charged using the external power source.

And S110, the slave battery is not fully charged, and the external power supply charges the slave battery.

In this embodiment, if the slave battery is not fully charged, the external power supply is controlled to charge only the slave battery. After the device controls the external power supply to charge the slave battery, whether the first battery and the second battery are in a combined state or not can be continuously detected.

And S111, if the battery is in the non-combined state, checking the electric quantity of the slave battery.

In this implementation, the first battery and the second battery are in an unassembled state, i.e., the first battery and the second battery operate in a separated state. At this time, the device may check the electric quantity of the slave battery, specifically, as described above, the battery management module in the slave battery may obtain the state information of the slave battery including the electric quantity, and send the state information to the micro control module of the display module, and then the micro control module sends the state information of the slave battery to the main operation module of the main control module through the wireless communication module.

S112, determining whether the electric quantity of the slave battery is less than 10%, and if so, executing a step S113; if not, the process returns to step S111.

In this embodiment, it is determined whether the slave battery charge level is less than 10%, i.e., whether the slave battery charge level is less than a charge level threshold corresponding to an under-power condition, which is 10%. When the electric quantity of the slave battery is less than 10%, the slave battery needs to be charged.

And S113, if the battery power is less than 10%, prompting the user to enter a combined state.

In this embodiment, if the electric quantity of the slave battery is less than 10%, a prompt for entering the combined state is given, and the prompt is used for prompting a user to physically combine the master control module and the display module.

S114, determining whether the combination state is entered, if so, executing the flow from the step S102 to the step S110; if not, the process returns to step S113.

In this embodiment, whether to enter the combination state is determined by determining whether the wired communication modules in the main control module and the display module can normally communicate. And if the main control module and the display module are communicated in a wired mode, determining that the first battery and the second battery enter a combined state.

In the embodiment, a proper battery management strategy is gradually determined according to whether the master battery and the slave battery work in a combined state, and the endurance time of the master battery and/or the slave battery can be reasonably increased, so that the service life of the equipment is prolonged, and the use experience of a user is improved. In addition, the main battery can also charge the auxiliary battery, thereby having convenience in use.
