The memory 1005 may be a high-speed RAM memory or a non-volatile memory (e.g., a magnetic disk memory). The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the terminal structure shown in fig. 1 does not constitute a limitation of the terminal device and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a kind of computer-readable storage medium, may include therein an operating system, a network communication module, a user interface module, and a battery-powered control program of a terminal device.
In the terminal shown in fig. 1, the network interface 1004 may be used for data communication with a backend server; the user interface 1003 may be used for data communication with a client (user side); when the terminal is a terminal device, the processor 1001 may be configured to call a battery power control program of the terminal device in the memory 1005, and perform the following operations:

and when the second temperature is less than or equal to a second maximum safe temperature and/or the first electric quantity is greater than or equal to a first preset electric quantity, switching to the second power supply battery to supply power to the terminal equipment.
Referring to fig. 2, fig. 2 is a schematic flowchart of a first embodiment of a battery power supply control method of a terminal device according to the present application.
While a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than here.
The battery power supply control method of the terminal equipment comprises the following steps:
step S10, acquiring a first temperature of a first power supply battery currently supplying power to the terminal equipment;
the terminal device may be a VR headset, a mobile phone, a computer, or the like, where the VR headset is used as the terminal device to analyze and describe the battery power supply control method of the terminal device. Because the power consumption of the VR head-mounted equipment is high, in order to prolong the working time of the VR head-mounted equipment and improve the experience of a user, the VR head-mounted equipment is provided with double batteries which are a main battery and an auxiliary battery respectively, wherein the main battery is detachable and is mainly responsible for supplying power; the auxiliary battery is not detachable and is mainly responsible for supplying power when the main battery is detached and replaced.
The Android system only processes a single battery state currently, or only processes a power supply battery state under the condition of double batteries, and cannot acquire double battery information at the same time and perform corresponding processing. Therefore, the method and the device for obtaining the first attribute information of the first power supply battery and the storage position of the second attribute information of the second power supply battery are obtained; and storing the first attribute information to a storage position of second attribute information of a second power supply battery, wherein the storage position of the second attribute information refers to a structure body where the second attribute information is located. In one embodiment, the states of the main battery and the auxiliary battery are distinguished in a Hardware Abstraction Layer (HAL) and an application architecture layer (Framework), and all battery attributes in the main battery structure are added by one copy and all battery attributes of the main battery are added to a structure of the auxiliary battery, and at this time, the main battery and the auxiliary battery share the same structure, where the structure is a term in the art of codes, for example, a structure is defined as a battery, and then battery attributes such as electric quantity, voltage, current and temperature can be set inside the structure. Then, attribute information of the main battery and the sub-battery is named using different parameters so as to distinguish the attribute information of the main battery and the sub-battery, for example, the structure includes attribute information of electric quantity 1, electric current 1, voltage 1, temperature 1, electric quantity 2, electric current 2, voltage 2, temperature 2, and the like, where the number 1 is attached as the attribute information of the main battery, and the number 2 is attached as the attribute information of the sub-battery. Because the system originally has only one battery, the interfaces are designed for the condition of one battery, and when the battery is added, the interfaces need to be added, so that the number of the interfaces is increased, and the code modification is troublesome. The operation of the application does not need to additionally increase the interface, but adapts to the interface by changing the data, so that the situation that all interfaces of the HAL and the Framework only adapt to one battery parameter can be solved. And simultaneously, according to the configuration of the auxiliary battery, the battery attribute of the main battery is obtained and configured, so that the HAL can read the data of the main battery and the auxiliary battery from the correct node.
In this embodiment, when the VR headset receives an acquisition instruction for acquiring attribute information, the driving interface is called, and the attribute information of the main battery and the auxiliary battery is acquired based on the driving interface, where the attribute information includes a battery capacity, a battery voltage, a battery current, a battery temperature, a remaining time, and the like. Then, acquiring a first temperature of a current power supply first power supply battery according to the attribute information, wherein the first power supply battery in the application refers to a main battery, and the first temperature refers to the temperature of the current main battery; the second power supply battery is referred to as a sub-battery.
Step S20, when the first temperature is higher than a first preset temperature, acquiring a second temperature and/or a first electric quantity of the second power supply battery;
when the first temperature is higher than the first preset temperature, a second temperature and/or a first electric quantity of the second power supply battery need to be acquired, for example, the driving interface is called, attribute information of the secondary battery is acquired based on the driving interface, and the second temperature and the first electric quantity of the second power supply battery are acquired according to the attribute information.
And step S30, when the second temperature is less than or equal to a second maximum safe temperature and/or the first electric quantity is greater than or equal to a first preset electric quantity, switching to the second power supply battery to supply power to the terminal equipment.
It should be noted that, when the VR headset works, power consumption is high, and the temperature of the battery of the device is easily increased, if the VR headset does not dissipate heat in time or takes other measures to process, the operation of the device may be affected, for example, the problems of jamming, frame dropping, etc. may occur, and even the device may crash and restart in a serious case. Meanwhile, because VR is the head-mounted device, if the temperature of power supply battery is too high, can influence user's wearing experience, consequently, the power supply battery upper limit temperature that VR head-mounted device set up is lower than general equipment, and VR head-mounted device is higher to the requirement of temperature.
The VR headset stores parameter information of the main battery and the sub-battery in advance, and refers to table 1, where table 1 lists partial parameter information of the main battery and the sub-battery.

Figure BDA0003177756490000081
Wherein, T1_ max > T1_ high > T1_ normal; t2_ max > T2_ high > T2_ normal. Since the electric quantity and the model number of the two batteries may be different, setting the same temperature to control the batteries reduces the time period in which the batteries can be normally used. And this application can prolong terminal equipment normal use time through setting up different temperatures to different batteries, can play the purpose of protection battery simultaneously.
When the VR head-mounted device detects that the temperature of the main battery is too high, whether the auxiliary battery meets the power supply condition or not is judged, and if yes, the main battery is switched to the auxiliary battery to supply power to the terminal device. In one embodiment, when the first temperature of the main battery is higher than a first preset temperature, the second temperature and/or the first electric quantity of the auxiliary battery are/is acquired; then, when the second temperature of the auxiliary battery is less than or equal to the second maximum safe temperature and/or the first electric quantity is greater than or equal to the first preset electric quantity, switching to the auxiliary battery to supply power to the terminal equipment; and when the second temperature of the auxiliary battery is higher than the second maximum safe temperature and/or the first electric quantity is lower than the first preset electric quantity, executing shutdown operation or outputting alarm information. For example, in the process of supplying power to the main battery, if the temperature T1 of the main battery is greater than the maximum temperature T1_ max, that is, T1 is greater than or equal to T1_ max, it indicates that the current temperature of the main battery is too high, which may affect the wearing experience of the user. At the moment, acquiring attribute information of the auxiliary battery, acquiring the temperature T2 and/or the electric quantity C3 of the auxiliary battery based on the attribute information, and if the temperature T2 of the auxiliary battery is less than or equal to the highest safe temperature T2_ high, namely T2 is less than or equal to T2_ high, indicating that the temperature T2 of the auxiliary battery is the safe temperature at present, switching the main battery to the auxiliary battery to supply power to the terminal equipment; or if the electric quantity C3 of the auxiliary battery is greater than or equal to C2, namely C3 is greater than or equal to C2, the electric quantity C3 of the current auxiliary battery meets the electric quantity power supply condition, and at the moment, the main battery is switched to the auxiliary battery to supply power to the terminal equipment; or if the temperature T2 of the auxiliary battery is less than or equal to the highest safe temperature T2_ high, and the electric quantity C3 of the auxiliary battery is greater than or equal to C2, that is, T2 is less than or equal to T2_ high, and C3 is greater than or equal to C2, it indicates that the current temperature T2 and the electric quantity C3 of the auxiliary battery simultaneously satisfy the power supply condition, and at this time, the main battery is switched to the auxiliary battery to supply power to the terminal device. Wherein if the temperature T2 of the sub-battery is higher than the maximum safe temperature T2_ high, or the electric quantity C3 of the sub-battery is lower than C2, i.e. T1> T2_ high, or C3< C2; or T2> T2_ high, and C3< C2, which indicate that the temperature T2 and the electric quantity C3 of the current auxiliary battery do not meet the power supply condition, at this time, the terminal device automatically shuts down the main battery at high temperature, or sends alarm information to the user to prompt the user that the current battery temperature is too high.
In the present application, the battery power supply control method of the terminal device is explained by analyzing with a dual battery as an example, but for a terminal device with multiple batteries (3 or more), the method of the present application can be similarly set according to the main and auxiliary power supply relationship.
The embodiment obtains a first temperature of a first power supply battery currently supplying power to the terminal equipment; when the first temperature is higher than a first preset temperature, acquiring a second temperature and/or a first electric quantity of a second power supply battery; and when the second temperature is less than or equal to the second maximum safe temperature and/or the first electric quantity is greater than or equal to the first preset electric quantity, switching to a second power supply battery to supply power to the terminal equipment. According to the embodiment of the application, when the temperature of the current first power supply battery is too high, the second power supply battery is switched to supply power to the terminal equipment, the situation that the terminal equipment is shut down due to direct high temperature is avoided, and user experience is improved.
Further, referring to fig. 3, a second embodiment of the battery power supply control method of the terminal device of the present application is proposed.
The second embodiment of the battery power supply control method of the terminal device differs from the first embodiment in that, after the step of switching to the second power supply battery to supply power to the terminal device, the battery power supply control method of the terminal device includes:
step S31, acquiring a first temperature and/or a second electric quantity of the first power supply battery;
and step S32, when the first temperature is less than or equal to a second preset temperature and/or the second electric quantity is greater than or equal to a second preset electric quantity, switching to the first power supply battery to supply power to the terminal equipment.
It should be noted that, because the main battery is a main power supply battery, when the terminal device is powered on and operated, if the electric quantity of the main battery is greater than a preset value, for example, greater than C1_ min, the main battery supplies power; if the electric quantity of the main battery is smaller than the preset value, the auxiliary battery supplies power. Secondly, when the auxiliary battery supplies power, if the main battery is detected to meet the power supply condition, the auxiliary battery needs to be switched to the main battery to supply power to the terminal equipment.
In this embodiment, when the sub-battery supplies power, the temperature t1 and/or the electric quantity C4 of the main battery are/is obtained, and if the temperature t1 of the main battery is less than or equal to the second preset temperature and/or the electric quantity C4 is greater than or equal to the second preset electric quantity, at this time, the sub-battery is switched to the main battery to supply power to the terminal device. For example, if the temperature T1 of the main battery is less than or equal to T1_ normal, i.e., T1 ≦ T1_ normal, indicating that the temperature of the main battery is normal, at this time, the sub-battery is switched to the main battery to power the terminal device. If the electric quantity C4 of the main battery is larger than or equal to C1_ min, namely C4 is larger than or equal to C1_ min, the electric quantity of the main battery meets the power supply condition, and at the moment, the auxiliary battery is switched to the main battery to supply power to the terminal equipment. If the temperature T1 of the main battery is less than or equal to T1_ normal, and the electric quantity C4 is greater than or equal to C1_ min, namely T1 is less than or equal to T1_ normal, and C4 is greater than or equal to C1_ min, it is indicated that the temperature and the electric quantity of the main battery meet the power supply condition at the moment, and at the moment, the auxiliary battery is switched to the main battery to supply power to the terminal equipment.
In the embodiment, when the auxiliary battery supplies power, the temperature and/or the electric quantity of the main battery is acquired, whether the temperature and/or the electric quantity of the main battery meets the power supply condition is judged, if yes, the auxiliary battery is switched to the main battery to supply power to the terminal equipment, and therefore the main battery can be used as a main power supply battery.
Further, referring to fig. 4, a third embodiment of the battery power supply control method of the terminal device of the present application is proposed.
