DETAILED DESCRIPTION

It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

Refer to FIG. 1 , which is a flow chart of a first embodiment of a battery management method according to the present invention.

In this embodiment, the battery management method is applied to a wrist-worn device 1, as shown in FIG2, which is a schematic diagram of the structure of the wrist-worn device 1 in this embodiment. The wrist-worn device 1 includes a watch body battery charging control module 2, a watch body battery 3, a fuel gauge 4, a dial main control unit 5, a watch body LED display module 6, and a watch strap 7, wherein the dial main control unit 5 is connected to the watch body LED display module 6, and the watch body battery charging control module 2, the watch body battery 3, the fuel gauge 4, and the dial main control unit 5 form a charging circuit; the thin-film solar cell 13 in the watch strap 7 is connected to the watch body battery charging control module 2.

It should be noted that the wrist-worn device 1 includes a watch body battery charging module 2, a watch body battery 3, a fuel gauge 4, a dial main control unit 5, a watch body LED display module 6 and two watch straps 7. The watch body battery charging control module 2, the watch body battery 3, the fuel gauge 4 and the dial main control unit 5 form a charging circuit, and the thin-film solar cells 13 in the two watch straps 7 are both connected to the watch body battery charging control module 2.

It can be understood that, as shown in FIG3 , FIG3 is a schematic diagram of the structure of the strap 7 in this embodiment. Each strap 7 is built with a strap battery charging control module 8, a strap battery 9, a power meter 10, a strap main control unit 11, and a strap LED display module 12, wherein the strap main control unit 11 is connected to the strap LED display module 12, and the strap battery charging control module 8, the strap battery 9, the power meter 10, and the strap main control unit 11 form a charging circuit; the thin-film solar cell 13 is attached to the upper surface of the strap 7 and is connected to the strap battery charging control module 8.

In a specific implementation, the built-in strap battery charging control module, strap battery, fuel meter and strap main control unit in the strap 7 form a charging circuit, and each unit can communicate with each other. In this embodiment, a USB charging port 14 is also provided at the end of the strap 7, and the USB charging port 14 is equipped with a soft plug to prevent dust. There are two watch straps on the wrist-worn device, which are located on both sides of the watch body of the wrist-worn device. Each side watch strap is equipped with a watch strap battery charging control module 8, a watch strap battery 9, a power meter 10, a watch strap main control unit 11, and a watch strap LED display module 12. The watch strap main control unit 11 is connected to the watch strap LED display module 12, and the watch strap battery charging control module 8, the watch strap battery 9, the power meter 10 and the watch strap main control unit 11 form a charging circuit; the thin-film solar cell 13 is fitted and covered on the upper surface of the watch strap 7 and is connected to the watch strap battery charging control module 8, and a USB charging port is provided at the end of each side watch strap. Each side watch strap can be charged through a thin-film solar cell anytime and anywhere in strong light or weak light, whether it is removed or worn, and can be charged not only by a solar charging path, but also by an interface charging path, and charged through a USB charging port.

It should be noted that, when the strap 7 is connected and buckled with the watch body to achieve electrical connection, the strap main control unit 11 can send the current strap power obtained from the power meter 10 to the dial main control unit 5. When the current strap power of one of the straps 7 on both sides is not less than the first power threshold, the strap battery 9 of the strap 7 is used to power the watch body. When the current strap power of the straps 7 on both sides is less than the first power threshold, the watch body battery 3 is used to temporarily power the watch body. At the same time, the power meter 4 can monitor the watch body battery 3. The dial main control unit 5 obtains the power data of the watch body battery 3 monitored by the power meter 4. When the current power of the watch body battery 3 is less than the second power threshold, the thin-film solar cell 13 of the strap 7 is used to charge the watch body battery 3.

The battery management method in this embodiment includes:

Step S01: obtaining the connection status of the watch strap and the current power level of the watch body battery.

It should be noted that the executor of this embodiment is the dial main control unit of the wrist-worn device. The dial main control unit obtains the connection status of the strap and the current power of the watch body battery. When the connection status of the strap is a preset connection status, the current power of each strap battery is obtained, and the watch body power supply battery is determined according to the current power of the strap of each strap battery, and the watch body charging strategy is determined according to the current power of the watch body, the watch body is powered according to the watch body power supply battery, and the watch body battery is charged according to the watch body charging strategy.

It is understandable that the dial main control unit obtains in real time whether each strap is connected to the watch body to achieve electrical connection, thereby determining the connection status of each strap. At the same time, the built-in power meter in the wrist-worn device monitors the current power of the watch body battery in real time. The dial main control unit obtains the current power monitored by the power meter from the power meter, and the current power of the watch body battery is the current power of the watch body.

Step S02: when the strap connection state is a preset connection state, the current power of each strap battery is obtained, the watch body power supply battery is determined according to the current power of each strap battery, and the watch body charging strategy is determined according to the current power of the watch body.

It should be noted that the preset connection state refers to the state in which each strap and the watch body are connected and buckled to achieve electrical connection. When the connection state between each strap and the watch body is the preset connection state, the strap main control unit can send the current power of the strap obtained from the built-in power meter of the watch body to the dial main control unit. The dial main control unit determines the battery to power the watch body based on the current power of each strap battery obtained so that the wrist-worn device can work normally. The mode in which the watch body is powered by a battery to enable the wrist-worn device to work normally is the watch body power supply battery.

It is understandable that the dial main control unit determines whether the watch body battery needs to be charged according to the current power of the watch body. When it is determined that the watch body battery needs to be charged, a strategy for charging the watch body is generated. The strategy for charging the watch body is the watch body charging strategy. The watch body charging strategy includes a charging reminder strategy and a watch body charging path.

In a specific implementation, in order to ensure continuous power supply to the watch body, a suitable watch body power supply battery is selected. Furthermore, when the strap connection state is a preset connection state, the watch body power supply battery is determined according to the current power of the strap of each strap battery, including: when the strap connection state is a preset connection state, detecting whether the current power of the strap of each strap battery is less than a first power threshold; when the current power of the strap of each strap battery is not less than the first power threshold, comparing the current power of the strap of each strap battery; determining the watch body power supply battery according to the comparison result; and generating the watch body power supply battery according to the power strap battery.

It should be noted that when the strap connection state is the preset connection state, it is detected whether the current strap power of each strap battery is less than the first power threshold; when the current strap power of each strap battery is not less than the first power threshold, the current strap power of each strap battery is compared, and the strap battery with the smaller value of the current strap power of the two strap batteries is determined as the watch body power supply battery. Further, the determination of the watch body power supply battery according to the comparison result includes: determining the strap battery with the lowest current strap power among the strap batteries according to the comparison result; and using the strap battery with the lowest current strap power among the strap batteries as the watch body power supply battery.

It can be understood that when the current power levels of the strap batteries on both sides are not less than the first power threshold and the current power levels of the strap batteries are not equal, the side with low power level is used first to power the watch body. The comparison result is used to find the strap battery with the lowest current power level among the strap batteries on both sides, and the strap battery with the lowest current power level is used as the watch body power supply battery to power the watch body. For example, if the first power threshold is 20%, the current power levels of the left strap battery and the right strap battery are not less than 20%, the current power level of the left strap battery is 35%, and the current power level of the right strap battery is 40%, then the right strap battery is the watch body power supply battery, and when the watch body is powered by the watch body power supply battery, the watch body is powered by the power supply strap battery on the low power side.

In a specific implementation, in order to ensure the long battery life of the wrist-worn device, a suitable watch body power supply battery is selected in different situations. Furthermore, when the watch strap connection state is a preset connection state, after detecting whether the current strap power of each strap battery is less than a first power threshold, it also includes: when the current strap power of each strap battery is less than the first power threshold, determining the watch body power supply battery according to the watch body battery; when the current strap power of the first strap battery among the current strap power of each strap battery is less than the first power threshold and the current strap power of the second strap battery is not less than the first power threshold, determining the watch body power supply battery according to the second strap battery.

It should be noted that when the current power of each strap battery is less than the first power threshold, the watch body battery is used as the watch body power supply battery. That is, when the current power of each strap battery is less than the first power threshold, the dial main control unit selects the watch body battery to power the watch body, temporarily meeting the power supply function and ensuring the basic function of the watch body. Or when the strap connection state is not the preset connection state, that is, when the strap is removed, the watch body battery is also used as the watch body power supply battery, and the watch body is powered by the watch body battery.

It can be understood that when the current power of the strap battery on one side is less than the first power threshold and the current power of the strap battery on the other side is not less than the first power threshold, the strap battery with the current power of the strap not less than the first power threshold is used to power the watch body, and the strap battery with the current power of the strap not less than the first power threshold is used as the watch body power supply battery.

It should be understood that in order to ensure that the battery of the watch body has sufficient power so that the watch body can be powered normally when the battery of the watch body is used to power the watch body subsequently, further, when the connection state of the watch strap is a preset connection state, the watch body charging strategy is determined according to the current power of the watch body, including: when the connection state of the watch strap is a preset connection state, detecting whether the current power of the watch body is less than a second power threshold; when the current power of the watch body is less than the second power threshold, generating a third reminder strategy to remind the user that the battery of the watch body is low on power, and charging the battery of the watch body according to the solar charging path.

In a specific implementation, when the strap connection state is the preset connection state, it is detected whether the current power of the watch body is less than the second power threshold. When the current power of the watch body is less than the second power threshold, a third reminder strategy is generated. The third reminder strategy is a light reminder strategy in this embodiment, and can also be a voice broadcast strategy or other reminder strategies. This embodiment does not limit this. The dial main control unit sends the third reminder strategy to the watch body LED display module, and the watch body LED display module drives the RGB LED to flash red light according to the third reminder strategy to remind the user that the battery of the watch body is low. At the same time, the dial main control unit sends a watch body charging instruction to the watch body battery charging control module, and the watch body battery charging control module starts the solar charging path and uses the thin-film solar cells of the strap to charge the watch body battery. When using the thin-film solar cells of the strap to charge the watch body battery, the thin-film solar cells on both sides of the strap can be selected to charge the watch body battery at the same time, or a thin-film solar cell can be randomly selected to charge the watch body battery, or the thin-film solar cell on the side of the strap with a high current power can be selected to charge the watch body battery. This embodiment does not limit this.

It should be noted that when the connection state of the watch strap is not the preset connection state, it is also necessary to detect whether the current power of the watch body is less than the second power threshold. When the current power of the watch body is less than the second power threshold, a third reminder strategy is generated to remind the user that the battery of the watch body is low, so that the user can buckle the watch strap to connect the watch body.

It can be understood that when the watch body battery is charging, the power of the watch body battery is monitored in real time. If the power of the watch body battery is fully charged, the dial main control unit sends a charging end instruction to the watch body battery charging control module and the watch body LED display module, so that the watch body battery charging control module ends charging and the watch body LED display module emits blue light.

Step S03: supplying power to the watch body according to the watch body power supply battery, and charging the watch body battery according to the watch body charging strategy.

It should be noted that after the watch body power supply battery is determined, the watch body is powered by the watch body power supply battery, and the watch body is charged according to the watch body charging strategy.

This embodiment applies the battery management method to a wrist-worn device, wherein the wrist-worn device includes a watch body battery charging control module, a watch body battery, a fuel gauge, a dial main control unit, a watch body LED display module, and a watch strap, wherein the dial main control unit is connected to the watch body LED display module, and the watch body battery charging control module, the watch body battery, the fuel gauge, and the dial main control unit form a charging circuit; the thin-film solar cell in the watch strap is connected to the watch body battery charging control module. The watch strap has a watch strap battery charging control module, a watch strap battery, a fuel gauge, a watch strap main control unit, and a watch strap LED display module built in, wherein the watch strap main control unit is connected to the watch strap LED display module, and the watch strap battery charging control module, the watch strap battery, the fuel gauge, and the watch strap main control unit form a charging circuit; the thin-film solar cell is laminated and covered on the upper surface of the watch strap and is connected to the watch strap battery charging control module. The battery management method obtains the strap connection state and the current power of the watch body battery; when the strap connection state is a preset connection state, the current power of each strap battery is obtained, the watch body power supply battery is determined according to the current power of each strap battery, and the watch body charging strategy is determined according to the current power of the watch body; the watch body is powered according to the watch body power supply battery, and the watch body battery is charged according to the watch body charging strategy. Through the above method, when the strap connection state is a preset connection state, the watch body power supply battery is determined according to the current power of the strap of each strap battery, the watch body is powered according to the watch body power supply battery, the watch body charging strategy is determined according to the current power of the watch body, and the watch body battery is charged according to the watch body charging strategy, which improves the long-term battery life of the wrist-worn device, reduces the volume and capacity of the single body battery of the watch body, realizes the lightweight design of the wrist-worn device, and improves the user experience.

Refer to FIG. 4 , which is a flow chart of a second embodiment of a battery management method according to the present invention.

In this embodiment, the battery management method is applied to the watch strap 7. As shown in FIG3 , the watch strap 7 is equipped with a watch strap battery charging control module 8, a watch strap battery 9, a fuel gauge 10, a watch strap main control unit 11, and a watch strap LED display module 12. The watch strap main control unit 11 is connected to the watch strap LED display module 12. The watch strap battery charging control module 8, the watch strap battery 9, the fuel gauge 10, and the watch strap main control unit 11 form a charging circuit. The thin-film solar cell 13 is adhered to and covers the upper surface of the watch strap 7 and is connected to the watch strap battery charging control module 8.

It should be noted that the built-in strap battery charging control module, strap battery, fuel meter and strap main control unit in the strap 7 form a charging circuit, and the various units can communicate with each other. In this embodiment, a USB charging port 14 is also provided at the end of the strap 7, and the USB charging port 14 is equipped with a soft plug to prevent dust.

It can be understood that the power meter 10 can monitor the power of the strap battery 9, and the strap main control unit 11 obtains the power data monitored by the power meter 10. When the strap battery 9 needs to be charged, it sends an instruction to the strap battery charging control module 8, and the strap battery charging control module 8 turns on the solar charging path or the interface charging path to charge the strap battery 9. When the strap battery is not full, the thin-film solar cell 13 can always charge the strap battery through the strap battery charging control module 8. When the power of the strap battery 9 is too low, the strap main control unit 11 can send a reminder strategy, and the strap LED display module 12 drives the RGB LED to emit red light according to the reminder strategy. When the strap battery 9 is fully charged, the strap main control unit 11 can send a reminder strategy, and the strap LED display module 12 drives the RGB LED to emit blue light according to the reminder strategy.

In this embodiment, the battery management method includes the following steps:

Step S10: Obtain the current power level of the strap battery.

It should be noted that the executor of this embodiment is the strap main control unit in the strap, which obtains the current power of the strap battery, determines the strap charging path according to the current power of the strap, and charges the strap battery according to the strap charging path.

It can be understood that the built-in fuel gauge in the strap will monitor the current power of the strap battery in real time, and the strap main control unit obtains the current power monitored by the fuel gauge from the fuel gauge, and the current power of the strap battery is the current power of the strap.

Step S20: determining a charging path for the watch strap according to the current power level of the watch strap.

It should be noted that the strap main control unit determines whether the strap battery needs to be charged according to the current power of the strap, and determines the path for charging the strap battery when the strap battery needs to be charged. The strap charging path includes a solar charging path and an interface charging path. The solar charging path refers to the path for charging the strap battery through a thin-film solar cell, and the interface charging path refers to the path for charging the strap battery through a USB interface.

It can be understood that in order to ensure that the strap battery has sufficient power to ensure the normal use and long battery life of the wrist-worn device, further, determining the strap charging path according to the current power of the strap includes: when the current power of the strap is less than the first power threshold, generating a first reminder strategy so that the user can feedback the strap charging path according to the charging reminder strategy; charging the strap battery according to the strap charging path includes: when the strap charging path is the interface charging path, closing the solar charging path, and charging the strap battery according to the interface charging path; when the strap charging path is the solar charging path, closing the interface charging path, and charging the strap battery according to the solar charging path.

In a specific implementation, the current power of the strap is detected. When it is determined that the current power of the strap is less than the first power threshold, it means that the current power of the strap battery is about to run out. At this time, the strap battery needs to be charged as soon as possible. The strap main control unit generates a first reminder strategy based on the current power of the strap. The first reminder strategy is a light reminder strategy in this embodiment, and it can also be a voice broadcast strategy or other reminder strategy, which is not limited in this embodiment. The strap main control unit sends the first reminder strategy to the strap LED display module, and the strap LED display module drives the RGB LED to emit red light according to the first reminder strategy. In this embodiment, the first power threshold can be 20%, or other values, which is not limited in this embodiment.

It should be noted that after sending the first reminder strategy, it is determined whether the charging path fed back by the user is received in the preset time period. If the strap charging path fed back by the user is not received in the preset time period or the strap charging path fed back by the user in the preset time period is a solar charging path, the strap main control unit determines that the strap charging path is a solar charging path. At this time, the strap main control unit sends an instruction of the solar charging path to the strap battery charging control module, and the strap battery charging control module closes the interface charging path and charges the strap battery through the solar charging path. If the strap charging path fed back by the user in the preset time period is an interface charging path, the strap main control unit sends an instruction of the interface charging path to the strap battery charging control module, and the strap battery charging control module closes the solar charging path and charges the strap battery through the interface charging path.

Step S30: charging the watch strap battery according to the watch strap charging path.

It should be noted that after the strap charging path is determined, the strap battery can be charged through the determined strap charging path. In this embodiment, when the current power of the strap battery is not fully charged and the interface charging path is not enabled, the strap battery can be continuously charged through the solar charging path until the strap battery is fully charged. When charging the strap battery according to the strap charging path, it is not necessary to detect whether the strap is connected to the wrist-worn device, and when the strap is connected to the wrist-worn device, it is not necessary to detect whether the strap is worn.

It can be understood that in order to ensure the health of the battery of the watch strap, further, after charging the watch strap battery according to the watch strap charging path, it also includes: obtaining the watch strap charging power of the watch strap battery; when the watch strap charging power is a preset full charge, generating a second reminder strategy to remind the user that charging is completed and closing the watch strap charging path.

In a specific implementation, when it is determined that the solar charging path or the interface charging path is enabled to charge the watchband battery, the watchband main control unit obtains the power of the watchband battery monitored by the power meter during the charging process in real time. The power of the watchband battery monitored by the power meter during the charging process is the watchband charging power. The watchband charging power is detected to determine whether the watchband charging power is the preset full power. When the watchband charging power of the watchband battery is the preset full power, it means that the power of the watchband battery is saturated, and there is no need to continue charging. The watchband main control unit generates a second reminder strategy based on the watchband charging. The first reminder strategy is a light reminder strategy in this embodiment, and can also be a voice broadcast strategy or other reminder strategy, which is not limited in this embodiment. The watchband main control unit sends the second reminder strategy to the watchband LED display module, and the watchband LED display module drives the RGB LED to emit blue light according to the second reminder strategy to remind the user that charging is finished. At the same time, the watchband main control unit sends a path closing instruction to the watchband battery charging control module, and the watchband battery charging control module closes the watchband charging path according to the path closing instruction, including the solar charging path and the interface charging path.

This embodiment applies the battery management method to a watch strap, wherein the watch strap has a built-in watch strap battery charging control module, a watch strap battery, a fuel gauge, a watch strap main control unit, and a watch strap LED display module, wherein the watch strap main control unit is connected to the watch strap LED display module, and the battery charging control module, the watch strap battery, the fuel gauge, and the watch strap main control form a charging circuit; a thin-film solar cell is laminated and covered on the upper surface of the watch strap and connected to the watch strap battery charging control module. The battery management method includes: obtaining the current power of each watch strap battery; determining the watch strap charging path according to the current power of the watch strap; and charging the watch strap battery according to the watch strap charging path.
