detailed description

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

The terminal device and its battery safety monitoring method and system according to the embodiments of the present invention are described below with reference to the accompanying drawings.

FIG. 1 is a flowchart of a battery safety monitoring method for a terminal device. As shown in FIG. 1, the battery safety monitoring method of a terminal device according to an embodiment of the present invention includes the following steps:

S101. Acquire charging capacity information and discharging capacity information of a battery of a terminal device during a charging and discharging process.

In the embodiment of the present invention, a specific power detection circuit, program, or an independent battery safety monitoring APP specified by the manufacturer can be set in the terminal device, and then the battery charge of the terminal device can be detected through the specific power detection circuit, program or APP in the terminal device. Changes in battery capacity during discharge. For example, a battery safety monitoring APP that detects battery capacity can be installed in the terminal device, and the APP can be set to detect the corresponding charging capacity and discharging capacity when the battery is charged and discharged between two specific SOC values or voltage values.

Optionally, the terminal device may be, but not limited to, a smart phone, a tablet computer, a handheld reader, etc., and a battery of the terminal device may be a lithium battery.

S102. Obtain the capacity change during charging and discharging of the battery according to the charging capacity information and the discharging capacity information.

Specifically, the charging capacity when the battery is charged from the first SOC value to the second SOC value can be obtained, and the discharge capacity when the battery is discharged from the second SOC value to the first SOC value can be obtained, so as to obtain the charging capacity according to the charging capacity and the discharging capacity. Discharge capacity difference. For example, for a 2910mAh/4.4V battery, set the first SOC value to 0.3 and the second SOC value to 0.9. If the charging capacity of the battery is 1790mAh when the battery is charged from the first SOC value to the second SOC value, the battery will be charged from the second SOC value The discharge capacity when discharged to the first SOC value is 1776mAh, and the charge-discharge capacity difference is 14mAh. It is also possible to obtain the charging capacity when the battery is charged from the first voltage to the second voltage, and obtain the discharge capacity when the battery is discharged from the second voltage to the first voltage, so as to obtain the charge-discharge capacity difference according to the charge capacity and the discharge capacity. For example, for a 2910mAh/4.4V battery, set the first voltage to 3.7V and the second voltage to 4.2V. If the battery is charged from 3.7V to 4.2V, the charging capacity is 2985mAh. When the battery is discharged from 4.2V to 3.7V The discharge capacity of the battery is 2980mAh, and the charge-discharge capacity difference is 5mAh.

It should be noted that the battery is charged from the first SOC value to the second SOC value, and the battery is discharged from the second SOC value to the first SOC value, or the battery is charged from the first voltage to the second voltage, and the battery is discharged from the second SOC value. Discharging from the second voltage to the first voltage is a continuous charging and discharging process of the battery. It can be understood that a continuous discharge and charge process of the battery can also be detected, that is, the discharge capacity when the battery is discharged from the second SOC value to the first SOC value is obtained first, and then the discharge capacity when the battery is charged from the first SOC value to the second SOC value is obtained. Charge capacity, or first obtain the discharge capacity when the battery is discharged from the second voltage to the first voltage, and then obtain the heavy capacity when the battery is discharged from the first voltage to the second voltage, and then calculate the difference between the two.

S103, judging whether the battery has potential safety hazards according to the capacity change during charging and discharging of the battery.

Specifically, it is judged whether the charge-discharge capacity difference is in the preset capacity interval, if the charge-discharge capacity difference is in the preset capacity interval, it is judged that the battery is in a normal state; if the charge-discharge capacity difference is not in the preset capacity interval , it is judged that the battery has potential safety hazards.

Wherein, the preset capacity range may be 0-20mAh, which may be pre-stored in the memory of the terminal device, so as to be recalled when needed.

For example, if the charge-discharge capacity difference of 14mAh is within the preset capacity range of 0-20mAh, it can be judged that the battery is in a normal state; if the terminal device falls and the charge-discharge capacity difference detected by the APP is 200mAh, it is not within the preset capacity range. If the capacity range is 0-20mAh, it can be judged that the battery in the terminal device has potential safety hazards.

S104, if it is determined that the battery has potential safety hazards, the control terminal device sends out a reminder message that the battery is abnormal.

For example, when the APP judges that the battery has potential safety hazards, it can display text information on the corresponding interface of the APP, such as "the battery is abnormal, please replace the battery in time".

For example, as shown in Figure 2, connect the charging port of a terminal device (such as a smart phone) to an adapter for charging. When the lithium battery in the terminal device is fully charged, disconnect the connection between the charging port and the adapter, and turn on the smart phone. The battery safety monitoring APP installed in the mobile phone can display the full voltage such as 4.4V on the APP application interface at this time. Then you can open the preset power-consuming load APP (such as video software, etc.) installed in the smart phone, and the battery will be discharged at a certain discharge current. When the application interface shows that the battery voltage reaches the cut-off voltage such as 3.7V, the battery safety monitoring APP The discharge capacity information of the battery can be calculated, that is, the battery capacity.

Further, turn off the power-consuming load APP, connect the charging port of the smartphone to the adapter, and charge the battery with a certain charging current. When the battery is fully charged, the application interface of the battery safety monitoring APP will display that the voltage of the battery is fully charged. When the voltage is 4.4V, the battery safety monitoring APP can calculate the charging capacity information of the battery. Then, according to the charging capacity information and discharging capacity information, the capacity change during charging and discharging of the battery is obtained, such as the difference between the charging capacity and the discharging capacity, and it is judged according to the difference whether the battery has a safety hazard. When judging that the battery has a safety hazard, it can be Display reminder information on the application interface of the battery safety monitoring APP, such as "there is an abnormality in the battery, please replace the battery in time" to remind the user to replace the battery or repair the battery in time.

Therefore, the battery safety monitoring method of the embodiment of the present invention judges whether the battery has a potential safety hazard by detecting the change information of the battery charge and discharge capacity, and when the battery has a potential safety hazard, the terminal device is controlled to send a reminder message that the battery is abnormal, so as to Remind users to deal with batteries with safety hazards in time, so as to avoid possible safety accidents in advance.

According to an embodiment of the present invention, the abnormality of the battery may include a local short circuit abnormality and an abnormality of extrusion damage. For example, when a terminal device falls from a high place, it may cause a partial short circuit and/or crush damage to the battery, which may cause abnormal heating of the battery in the terminal device during charging and discharging, affecting the normal use of the terminal device.

Further, when it is judged that the battery has potential safety hazards, corresponding functions of the terminal equipment are also restricted. For example, when it is judged that the battery has potential safety hazards, the terminal device can be controlled to stop charging the battery, that is, the terminal device will not charge the battery after it is connected to the adapter; it can also be controlled to prohibit the terminal device from starting apps that consume large and fast power consumption, Such as online game APP, video APP, etc.

In order to facilitate the understanding of the terminal device and its battery safety monitoring method in the above-mentioned embodiments of the present invention, the following examples may be used in conjunction with FIG. 3 and FIG. 4 to illustrate:

In an example of the present invention, as shown in FIG. 3, the terminal device and its battery safety monitoring method may include the following steps:

S201. Obtain the charging capacity when the battery is charged from the first SOC value to the second SOC value, and acquire the discharge capacity when the battery is discharged from the second SOC value to the first SOC value.

S202. Obtain a charge-discharge capacity difference according to the charge capacity and the discharge capacity.

S203, judging whether the charge-discharge capacity difference is within the preset capacity range, if the charge-discharge capacity difference is within the preset capacity range, execute step S204; otherwise, execute step S205

S204, judging that the battery is in a normal state.

S205. Determine that the battery has potential safety hazards, and control the terminal device to send a reminder message that the battery is abnormal.

For example, referring to Figure 2, when the charging port of a terminal device (such as a smart phone) is connected to an adapter for charging, the battery safety monitoring APP installed in the smart phone is opened (you can only run this APP), and when the battery SOC of the smart phone When the SOC value is the first SOC value, the APP starts to detect the charging capacity of the battery. When the battery SOC of the smartphone reaches the second SOC value, the APP stops detecting the charging capacity. At this time, the detected charging capacity of the battery is A, and displays show.

Further, disconnect the connection between the charging port of the terminal device and the adapter, and start using the application software (such as video, audio software, etc.) installed in the terminal device, the battery starts to discharge, when the SOC of the battery reaches the second SOC value , the battery safety monitoring APP starts to detect the discharge capacity of the battery. When the battery discharges to the first SOC value, the APP stops the detection of the discharge capacity. The difference between them is |A-B|, and it is judged whether |A-B| is in the preset capacity range. If so, it is judged that the battery is in a normal state. Otherwise, it is judged that the battery has potential safety hazards, and then a reminder message can be displayed on the APP application interface. For example, "The battery is abnormal, please replace the battery in time" to remind the user to replace the battery or repair the battery in time.

In another example of the present invention, as shown in FIG. 4, the terminal device and its battery safety monitoring method may include the following steps:

S301. Acquire the charging capacity when the battery is charged from the first voltage to the second voltage, and acquire the discharge capacity when the battery is discharged from the second voltage to the first voltage.

S302. Obtain a charge-discharge capacity difference according to the charge capacity and the discharge capacity.

S303, judging whether the charge-discharge capacity difference is within a preset capacity range, if the charge-discharge capacity difference is within the preset capacity range, execute step S304; otherwise, execute step S305.

S304, judging that the battery is in a normal state.

S305. Determine that the battery has potential safety hazards, and control the terminal device to send a reminder message that the battery is abnormal.

For example, referring to Figure 2, when the charging port of a terminal device (such as a smart phone) is connected to an adapter for charging, the battery safety monitoring APP installed in the smart phone is opened (only the APP is run), and when the battery voltage of the smart phone is At the first voltage value, the APP starts to detect the charging capacity of the battery. When the battery voltage of the smartphone reaches the second voltage value, the APP stops detecting the charging capacity. At this time, the detected charging capacity of the battery is M, and it is displayed on the display interface .

Further, disconnect the connection between the charging port of the terminal device and the adapter, and start using the application software (such as video, audio software, etc.) installed in the terminal device, the battery starts to discharge, when the voltage of the battery reaches the second voltage value , the battery safety monitoring APP starts to detect the discharge capacity of the battery. When the battery discharges to the first voltage value, the APP stops the detection of the discharge capacity. The difference between them is |M-N|, and judge whether |M-N| is in the preset capacity range, if yes, judge that the battery is in a normal state, otherwise, judge that the battery has a potential safety hazard, and then display a reminder message on the APP application interface, For example, "The battery is abnormal, please replace the battery in time" to remind the user to replace the battery or repair the battery in time.

Therefore, by detecting the difference between the charging capacity and discharging capacity of the battery, it is possible to predict whether the battery is abnormal, and when the battery is abnormal, the terminal device is controlled to send out a reminder message of the abnormality of the battery, so as to remind the user to deal with the abnormal battery in time. , so as to avoid possible safety accidents in advance.

In some embodiments of the present invention, it is also possible to acquire the battery capacity at two moments in a certain period of time during the charging and discharging process of the battery of the terminal device. For example, when the battery is being charged, the battery capacity M is obtained at time T, and the battery capacity N is obtained again at time T+t. If after time t, the change value of battery capacity, that is, N-M is not in the preset capacity range, it can be judged Batteries are a safety hazard.

It should be noted that there may be a corresponding relationship between the time t and the preset capacity interval, and the corresponding relationship may be pre-stored in a memory so as to be recalled when needed.

In order to verify the feasibility and effectiveness of the battery safety monitoring method for terminal equipment in the embodiment of the present invention, the following test experiments can be used to illustrate:

In an indoor room temperature environment, take 15 battery samples BLP627 with a specification of 2910mAh/4.4V (each battery sample is distinguished by its own battery barcode) as the test object, according to the capacity change before and after the battery sample is dropped, and the charge and discharge capacity change. Battery safety testing. The test data is shown in Table 1 below;

Table 1

It should be noted that the data of no voltage after the battery dropped in Table 1 is obviously abnormal, and the sample data that can be directly eliminated without testing is not used as reference data for comparison. For example, after the No. 1, No. 3, No. 7, No. 8, No. 11, and No. 14 batteries are dropped, the discharge capacity cannot be detected, that is, the batteries have obvious abnormalities, so they are not used as reference data for comparison.

As shown in Table 1, the test principle is illustrated by taking the No. 2 and No. 5 batteries as examples: before the No. 2 battery is dropped, the capacity is 2984mAh, and the charge-discharge capacity difference is 5mAh; after the drop, the capacity is 2967mAh, and the charge-discharge capacity difference is 3mAh. It can be seen that the capacity difference before and after the battery drop is 17mAh, which is in the preset capacity range of 0-20mAh, and the charge-discharge capacity difference after the drop is 3mAh, which is also in the preset capacity range of 0-20mAh, indicating that the No. 2 battery is in a normal state. Before the No. 5 battery was dropped, the capacity was 2986mAh, and the battery charge-discharge capacity difference was 9mAh. After the drop, the FPC (Flexible Printed Circuit, flexible circuit board) was damaged, and the capacity was 2960mAh, and the charge-discharge capacity difference was 27mAh. The capacity difference is 26mAh, which is not in the preset capacity range of 0-20mAh, and the charge-discharge capacity difference after the battery falls is 27mAh, which is not in the preset capacity range of 0-20mAh, indicating that the AA battery has potential safety hazards.

It can be concluded that after the battery is dropped and damaged, its charge and discharge capacity values will change greatly, and the degree of change will vary with the damage. And the greater the degree of damage, the greater the change in the charge and discharge capacity of the battery. In other words, it is possible to determine whether the battery is abnormal by detecting the change in the charge and discharge capacity of the battery.

To sum up, according to the battery safety monitoring method of the terminal device according to the embodiment of the present invention, it is possible to predict whether the battery has potential safety hazards based on the capacity change during charging and discharging of the battery, and control the terminal device to issue a battery abnormality when judging that the battery has potential safety hazards. Reminder information to remind users to deal with batteries with potential safety hazards in time, so as to avoid possible safety accidents in advance.

The present invention also proposes a non-transitory computer-readable storage medium on which a computer program is stored, and the feature is that, when the program is executed by a processor, the battery safety monitoring method of the above-mentioned embodiment is realized.

The non-transitory computer-readable storage medium in the embodiment of the present invention can determine whether the battery has a potential safety hazard by executing the above-mentioned battery safety monitoring method, and control the terminal device to send a reminder message that the battery is abnormal when it is judged that the battery has a potential safety hazard, so as to Remind users to deal with batteries with potential safety hazards in time, so as to avoid possible safety accidents in advance.

Referring to Figure 2, connect the charging port of the terminal device (such as a smart phone) to the adapter for charging. When the lithium battery in the terminal device is fully charged, disconnect the charging port from the adapter, and turn on the battery installed in the smart phone. Battery safety monitoring APP, at this time, the full voltage such as 4.4V can be displayed on the APP application interface. Then you can open the preset power-consuming load APP (such as video software, etc.) installed in the smart phone, and the battery will be discharged at a certain discharge current. When the application interface shows that the battery voltage reaches the cut-off voltage such as 3.7V, the battery safety monitoring APP The discharge capacity information of the battery can be calculated, that is, the battery capacity.

Further, turn off the power-consuming load APP, connect the charging port of the smartphone to the adapter, and charge the battery with a certain charging current. When the battery is fully charged, the application interface of the battery safety monitoring APP will display that the voltage of the battery is fully charged. When the voltage is 4.4V, the battery safety monitoring APP can calculate the charging capacity information of the battery.
