In the related technology, the battery power detection mode of the wearable product is simple, the precision is low, and the detection error is about 2% -5%.
In order to solve the above technical problem, the present application provides a battery discharge control method applied to a wearable product, and fig. 1 shows a flowchart of the battery discharge control method according to an embodiment of the present application. As shown in fig. 1, the method includes steps S11 to S13.

The bluetooth connection referred to in this application may be a bluetooth technology such as BT and Bluetooth Low Energy (BLE), and may also be other technologies capable of implementing short-distance communication between the terminal device and the wearable product. Therefore, the terminal equipment for sending the battery information and the wearable product are ensured to be in the same or similar external environment as far as possible, and the reliability of determining the percentage of the residual electric quantity of the wearable product based on the battery information is improved.
In a possible implementation manner, the battery information of any terminal device that has established a communication connection may also be received, then the distance between each terminal device and the wearable product is determined, and the battery information of the terminal device whose distance is less than or equal to the preset distance is used as a basis for determining the unavailable power consumption of the wearable product in step S12 below.

The preset distance can be set according to the distance between the wearable product and the terminal equipment under the condition that the user can carry the wearable product and the terminal equipment under the same environment. For example, the preset distance may be 1 meter.
In a possible implementation manner, the accuracy of the battery level detection manner of each terminal device is higher than that of the wearable product, and the type of the battery of each terminal device is the same as that of the wearable product. Types of batteries for wearable products may include wound batteries, gel state batteries, liquid state batteries, and the like. The battery capacity detection mode of the terminal equipment can be a mode combining battery modeling and coulometer capacity detection, and the capacity detection error is less than 1%.

The power usage information may indicate usage state information of the battery of the terminal device in the current environment, and the percentage of terminal unavailable power consumption (UUC) of the battery of the terminal device at the temperature of the current environment may be determined based on the power usage information. In the environment of different temperatures, the UUC percentages of the battery of the terminal device and the wearable product should be similar, so that the battery information of the terminal device can be used as a basis for determining the remaining battery capacity percentage and/or the shutdown voltage of the wearable product. The power usage information may include any one of: the percentage of the terminal electricity consumption which can not be used, the percentage of the terminal electricity consumption which can be used, the terminal electricity consumption which can not be used and the terminal electricity consumption which can be used. If the electricity usage information is the terminal unavailable electricity or the terminal available electricity, the battery information further needs to include a Full Charge Capacity (FCC) of the battery of the terminal device. Or the terminal device sends its FCC to the wearable product in advance before sending the battery information.
Wherein, before receiving battery information, wearable product need establish bluetooth with terminal equipment earlier and be connected to carry out battery information's transmission. The wearable product may first send a first request to the terminal device to obtain the battery information, and the terminal device may then return the battery information to the wearable product in response to the first request. The first request may further instruct the terminal device to send the battery information to the wearable product according to a preset feedback rule, where the preset feedback rule may include any one of: and sending the battery information at intervals of preset duration (namely, responding to the first request to carry out multiple times of sending of the battery information). And detecting that the starting time of the wearable product is longer than a preset time such as half an hour (responding to the first request to perform one-time transmission of the battery information). The battery information is sent when the electric quantity use information of the terminal equipment is determined to be changed, so that the wearable product can determine the percentage of the residual electric quantity of the battery and/or the shutdown voltage timely based on the change of the battery information.
In step S12, according to at least one piece of the battery information, an unusable power UUC of the wearable product is determined 0 。
If the battery information received by the wearable product is only one and comes from a certain terminal device, the unavailable electricity consumption of the wearable product can be determined directly based on the electricity consumption information in the battery information. The determination process comprises the following steps: whether the electricity consumption information in the battery information is the percentage of the terminal electricity consumption which cannot be used or not can be judged firstly, if not, the percentage of the terminal electricity consumption which cannot be used of the corresponding terminal equipment can be determined according to the electricity consumption information in the battery information; if so, no calculation is needed. Such as: and if the electricity usage information is the percentage of the available electricity of the terminal, the percentage of the unavailable electricity of the terminal is the difference between 100% and the percentage of the available electricity of the terminal. And if the electricity usage information is the terminal unavailable electricity, the percentage of the terminal unavailable electricity is the ratio of the terminal unavailable electricity to the full charge capacity of the battery of the terminal equipment. Then determining the percentage of the terminal electricity consumption which cannot be used as the percentage of the wearable product electricity consumption which cannot be used; the amount of non-usable power of the wearable product is then determined based on the percentage of non-usable power of the wearable product and the Remaining battery capacity (RM). The non-available power of the wearable product is the product of the percentage of the non-available power of the wearable product and the full charge capacity of the battery.
If the battery information is multiple and comes from different terminal equipment, then need filter a plurality of battery information, determine the power consumption that can not be used of wearable product based on the battery information of screening. The screening and determination process may include:

And then determining the lowest value of the plurality of terminal electricity utilization percentage as the wearable product electricity utilization percentage. And determining the unavailable electricity consumption of the wearable product based on the unavailable electricity consumption percentage of the wearable product and the residual capacity of the battery.
And the second method comprises the following steps: if the battery information also comprises the battery temperature, determining the percentage of the terminal unavailable electricity consumption of the first terminal equipment according to the battery information of the first terminal equipment with the lowest battery temperature by referring to the mode; determining the percentage of the terminal electricity consumption of the first terminal equipment as the percentage of the terminal electricity consumption of the first terminal equipment; and determining the unavailable electricity consumption of the wearable product according to the unavailable electricity consumption percentage of the wearable product and the residual capacity of the battery.

Similarly, the second mode selects to determine the unavailable electricity consumption of the wearable product according to the battery information of the terminal device with the lowest battery temperature, and can also ensure that the battery remaining electricity percentage of the wearable product is subsequently determined to be matched with the optimal discharge of the wearable product in the current external environment.

Wherein, the percentage SOC of the battery remaining capacity of the wearable product is determined 0 The process of (2) may be:
the non-electricity consumption of wearable product is UUC 0 Then, the following equation 1:
UUC 0 ＝FCC 0 ×SOC 0 ×X 0 ＝RM 0 ×X 0 equation 1
Wherein, FCC 0 Full charge capacity of battery for wearable product, X 0 Is the percentage of the wearable product that cannot be used. Wherein, 1-X 0 I.e. the percentage of the available power of the wearable product.
X 0 May be at least one of the terminals with a percentage of unusable powerThe percentage may be the smallest value, or may be the percentage of the terminal-unusable power corresponding to the first terminal device with the lowest battery temperature.
The following formula 2 is continuously utilized to calculate the percentage SOC of the wearable product 0 ：
In one possible implementation, the battery information may further include a battery temperature, and the method may further include: reducing a shutdown voltage of the wearable product according to a lowest battery temperature of the at least one battery temperature. Wherein the shutdown voltage is used to indicate that the wearable product is shutdown when an Open Circuit Voltage (OCV) is less than or equal to the shutdown voltage.
The shutdown voltage may also be referred to as a soft shutdown threshold of the wearable product, which is higher than a hard shutdown threshold of the wearable product (that is, a voltage value at which a Power Management Unit (PMU) of the wearable product triggers an under-voltage protection to shutdown the wearable product). The hard shutdown threshold can be determined according to the time of preparation operation of the wearable product for completing shutdown and the electric quantity required to be consumed in the time, and the hard shutdown threshold can be set according to the requirement. For example, if the time required for a wearable product to be powered off is 1s, and the capacity of the battery is 4000mAh, according to the circuit consumed in 1s for powering off, the following steps may be set: at normal temperature, the soft shutdown threshold may be 3.300V, and the hard shutdown threshold may be 3.000V.
