Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a battery detection method according to an embodiment of the present disclosure. In the embodiment of the application, the main execution body of the battery detection method is terminal equipment.

As shown in fig. 1, a battery detection method provided in an embodiment of the present application may include steps S101 to S103, which are detailed as follows:

in S101, when it is detected that a battery satisfies a set condition, an open-circuit voltage of the battery before discharge and a closed-circuit voltage of the battery after discharge are acquired.

In practical applications, for example, in the field of automobiles, an on-board terminal of a vehicle is generally provided with an emergency call function, which is used for triggering and making an emergency call after the vehicle is in collision or abnormal conditions, so as to obtain rescue. However, when a backup battery for ensuring that the emergency call function can be used in the vehicle is fed or an abnormality occurs, the emergency call function cannot be used, and thus, the battery needs to be detected in real time to ensure that the battery is in a healthy state.

Therefore, when a person using the vehicle needs to detect the battery, a detection instruction may be sent to the terminal device.

In this embodiment, the detection instruction detected by the terminal device may be: and detecting that a user triggers a preset operation aiming at the terminal equipment. The preset operation may be determined according to actual needs, and is not limited herein. Illustratively, the preset operation may be clicking a preset control of the terminal device, that is, if the terminal device detects that the user clicks the preset control, it is determined that the preset operation for the terminal device is detected; certainly, the preset operation may also be a time-triggered operation, and the terminal device may be configured with a corresponding workflow during running, where the workflow includes trigger nodes of a plurality of key events, where the key events include a battery detection event, and in this case, if the terminal device detects that the trigger node associated with the battery detection event is reached, the operations of S101 to S103 are executed to execute the detection operation on the battery.

Based on this, the terminal device may detect whether the battery satisfies the set condition in response to the detection instruction to determine whether the open-circuit voltage of the battery before discharge and the closed-circuit voltage of the battery after discharge can be acquired.

In an embodiment of the present application, the terminal device may specifically implement step S101 through S201 to S202 shown in fig. 2, which are detailed as follows:

in S201, when it is detected that a power supply of an electronic device in which the battery is located is in an on state, a battery parameter of the battery is acquired.

In this embodiment, the terminal device obtains the battery parameter of the battery when detecting that the power supply of the electronic device where the battery is located is in the on state.

It should be noted that, in order to ensure that stable open-circuit voltage and stable closed-circuit voltage of the battery are obtained subsequently, so as to improve the detection accuracy of the battery, the battery parameters of the battery include, but are not limited to: battery temperature, initial open circuit voltage, total time to charge the battery, and sleep time of the battery. Wherein, the total charging time of the battery refers to the accumulated charging time of the battery before the health detection is carried out.

In this embodiment, after obtaining the battery parameter of the battery, the terminal device may compare the battery parameter with the setting condition. The setting conditions may be set according to actual needs, and are not limited herein.

In some possible embodiments, since the battery parameters include, but are not limited to, a battery temperature, an initial open circuit voltage, a total charging time of the battery, and a sleep time of the battery, the setting conditions may include, but are not limited to, a first setting condition, a second setting condition, a third setting condition, and a fourth setting condition.

In this embodiment, the terminal device may set the setting condition corresponding to the battery temperature as a first setting condition, set the setting condition corresponding to the initial open-circuit voltage as a second setting condition, set the setting condition corresponding to the total charging time of the battery as a third setting condition, and set the setting condition corresponding to the sleep time of the battery as a fourth setting condition.

Wherein, the first setting condition may be: the battery temperature is within a set range. Wherein the set range may be [0 ℃,60 ℃ ].

The second setting condition may be: the initial open circuit voltage is greater than a first threshold. Wherein the first threshold may be 1.34v/cell.

The third setting condition may be: the total time of charging of the battery is greater than a second threshold. Wherein the second threshold may be 10 hours.

The fourth setting condition may be: the sleep time of the battery is greater than a third threshold. Wherein the third threshold may be 4 hours.

In an embodiment of the present application, the terminal device may execute step S202 when detecting that the battery parameters of the battery meet the set thresholds (e.g., the set range, the first threshold, the second threshold, and the third threshold), that is, each battery parameter meets the set condition corresponding to the battery parameter.

In another embodiment of the present application, when detecting that the battery parameters of the battery do not meet the set thresholds (e.g., the set range, the first threshold, the second threshold, and the third threshold), that is, at least one battery parameter does not meet the set condition corresponding to the battery parameter, the terminal device indicates that the battery does not meet the health detection condition, and therefore, the terminal device stops performing health detection on the battery.

In S202, if the battery parameter meets a set threshold, an open-circuit voltage of the battery before discharging and a closed-circuit voltage of the battery after discharging are obtained.

In this embodiment, when the terminal device detects that the battery parameter of the battery meets the set threshold, that is, each battery parameter meets the set condition corresponding to the battery parameter, it indicates that the battery meets the health detection condition, and therefore, the terminal device may obtain an open-circuit voltage of the battery before discharge and a closed-circuit voltage of the battery after discharge.

In another embodiment of the application, in a discharging process of the battery, if a power supply of the electronic device where the battery is located is in a shutdown state, or the battery is in an open-circuit state, or the battery is in a power supply state, or the electronic device is in a self-checking state, the terminal device cannot perform health detection on the battery, and therefore, when the battery is in a discharging stage, the terminal device stops performing health detection on the battery when detecting that the power supply of the electronic device where the battery is located is in the shutdown state, or the battery is in the open-circuit state, or the battery is in the power supply state, or the electronic device is in the self-checking state, and useless work and resource waste of the terminal device are avoided.

The terminal voltage of the battery in the Open circuit state is an Open Circuit Voltage (OCV). The open circuit voltage of a battery is equal to the difference between the positive electrode potential and the negative electrode potential of the battery when the battery is open-circuited (i.e., when no current is passing through the two electrodes).

The Closed Circuit Voltage (CCV) of the battery refers to a terminal Voltage of the battery after the battery is turned on. The terminal voltage is the voltage between the positive and negative poles of the battery, also called circuit terminal voltage or terminal voltage, and is equal to the work of electric field force moving unit positive charge from the positive pole of the battery to the negative pole of the battery along an external circuit.

In order to improve the detection accuracy, the terminal device may control the battery to discharge at a current of 750 milliamperes, and detect the closed circuit voltage of the battery after a discharge set time. Wherein the set time may be set to 500 milliseconds.

In S102, health detection is performed on the battery according to the open-circuit voltage and the closed-circuit voltage, so as to obtain a health detection result of the battery.

In the embodiment of the application, the health detection result of the battery comprises pass and fail. Wherein, pass means that the battery passes the health detection of the battery, and fail means that the battery fails the health detection of the battery.

In an embodiment of the present application, the terminal device may specifically obtain the health detection result of the battery through S301 to S302 shown in fig. 3, which is detailed as follows:

in S301, a state of health parameter of the battery is calculated according to the open-circuit voltage and the closed-circuit voltage, where the state of health parameter is an electrical parameter used for indicating a battery health degree.

In this embodiment, the state of health parameter is an electrical parameter for indicating the degree of health of the battery. The health status parameter and the resistance are isometrical parameters, i.e. the unit of the health status parameter is also ohm.

Note that the health state parameter refers to a DC-IR value.

In an embodiment of the present application, the terminal device may specifically obtain the state of health parameter of the battery through calculation in S401 to S403 shown in fig. 4, which is detailed as follows:

in S401, the internal resistance of the battery is acquired.

In this embodiment, the terminal device may determine the internal resistance of the battery according to a preset detection algorithm. The preset detection algorithm includes, but is not limited to: alternating current measurement and direct current measurement.

In the ac measurement method, also called as ac injection method, when measuring the internal resistance of the battery, a small ac current of 1Khz is applied to the positive and negative polarities of the battery, and the internal resistance value is obtained by measuring the response of the voltage.

The direct current measurement method, also known as direct current discharge method, is calculated according to the formula R = U/I. Specifically, the terminal device controls the battery to force a constant direct current (generally 40A-80A current is used) in a short time (generally 2-3 s), measures the voltage at two ends of the battery at the moment, and calculates the internal resistance of the battery according to the formula.

In S402, an open-circuit current of the battery is calculated according to the internal resistance and the open-circuit voltage.

In this embodiment, the terminal device may specifically calculate the open-circuit current of the battery according to the following formula:

where I represents the open current of the battery, OCV represents the open voltage of the battery, and R represents the internal resistance of the battery.

In S403, the health status parameter is calculated according to the open circuit current, the open circuit voltage, and the closed circuit voltage.

In this embodiment, the terminal device may specifically calculate the health state parameter of the battery according to the following formula:

DC-IR＝(OCV-CCV)/I；

wherein DC-IR represents a state of health parameter of the battery, OCV represents an open circuit voltage of the battery, CCV represents a closed circuit voltage of the battery, and I represents an open circuit current of the battery.

In another embodiment of the present application, due to the difference between the components and the accuracy of the AD sampling, an error exists in the calculation process of the state of health parameter of the battery, so that the terminal device may further calculate the state of health parameter of the battery through S501 to S502 shown in fig. 5, which is detailed as follows:

in S501, a detected deviation value of the battery is determined, where the detected deviation value is an error generated in the calculation of the state of health parameter of the battery.

In this embodiment, the terminal device may determine that the detection deviation value of the battery is 10%.

In S502, the health status parameter is calculated according to the open circuit voltage, the closed circuit voltage, and the detection deviation value.

Specifically, in this embodiment, the terminal device may calculate an initial state of health parameter of the battery according to the open-circuit voltage and the closed-circuit voltage of the battery, and then calculate a final state of health parameter of the battery according to the initial state of health parameter and the detected deviation value.

Wherein the battery final state of health parameter = initial state of health parameter (1-10%).

In some possible embodiments, the terminal device may specifically obtain the initial state of health parameter of the battery according to the calculation in steps S301 to S303.

In S302, determining a health detection result of the battery according to the health state parameter and a preset battery health degree table; and the battery health degree table records the corresponding relation between the health state parameter and the battery health degree.

In the embodiment of the application, the terminal equipment stores a preset battery health degree table in advance. The battery health degree table is used for recording the corresponding relation between the health state parameters and the battery health degree.

It should be noted that, because different batteries have different battery specifications, in order to improve the detection accuracy of the batteries, the terminal device may set different batteries corresponding to different battery health degree tables.

In the embodiment of the application, the terminal device may determine the battery health degree table corresponding to the battery health detection according to the battery for health detection, and then search the battery health degree corresponding to the battery health degree table according to the calculated battery health state parameter to determine the health detection result of the battery.

In S103, a preset processing action corresponding to the health detection result is executed.

In the embodiment of the application, the terminal device stores the corresponding relationship between the different health detection results and the processing actions in advance, so that after the terminal device obtains the health detection results of the battery, the terminal device can determine the processing action corresponding to the health detection results of the battery from the pre-stored corresponding relationship between the different health detection results and the processing actions, and execute the processing action.

In an embodiment of the present application, since the health detection result of the battery includes pass and fail, the terminal device may specifically implement step S103 through S601 to S602 shown in fig. 6, which are detailed as follows:

in S601, if the health detection result is positive, the health detection frequency of the battery is cleared.

In this embodiment, when the terminal device detects that the health detection result of the battery passes, it indicates that the battery is in a healthy state, and therefore, the terminal device may zero the health detection times of the battery, so as to newly count the health detection times of the battery in the subsequent health detection of the battery.

In S602, if the health detection result is failed, accumulating the health detection times of the battery; and if the health detection times are greater than the set times, outputting prompt information for prompting that the battery is in a dangerous state.

In this embodiment, when the terminal device detects that the health detection result of the battery is failed, it indicates that the battery may be in a dangerous state, and therefore, in order to further determine whether the battery is in a dangerous state, the terminal device may accumulate the health detection times of the battery.

After obtaining the health detection times of the battery, the terminal device may compare the health detection times with a set number. The set number may be determined according to actual needs, and is not limited herein, and for example, the set number may be 8.

In an embodiment of the present application, when the terminal device detects that the number of times of health detection of the battery is greater than the set number of times, it indicates that the battery is actually in a dangerous state, and therefore, the terminal device may input prompt information for prompting that the battery is in a dangerous state.

In another embodiment of the present application, when the terminal device detects that the number of health detection times of the battery is less than or equal to the set number of times, it indicates that the terminal device still cannot determine whether the battery is in a dangerous state, and therefore, the terminal device may retain the number of health detection times of the battery and continue to perform health detection on the battery until the number of health detection times of the battery is greater than the set number of times or the health detection result of the battery passes.

Through the mode, the terminal equipment can output the prompt information for prompting that the battery is in the dangerous state only when the health detection times of the battery are detected to be greater than the set times, so that the condition that the battery is failed due to the fact that the health detection result appears in accidental power failure is avoided, then the terminal equipment still frequently outputs the prompt information, and the accuracy of health detection of the battery is improved.

As can be seen from the above, according to the battery detection method provided in the embodiment of the present application, when it is detected that the battery meets the set condition, the open-circuit voltage of the battery before discharging and the closed-circuit voltage of the battery after discharging are obtained; carrying out health detection on the battery according to the open-circuit voltage and the closed-circuit voltage to obtain a health detection result of the battery; and executing a preset processing action corresponding to the health detection result. Compared with the prior art that the battery health state of the battery is determined directly according to the open-circuit voltage of the battery, the health detection is carried out on the battery by combining the open-circuit voltage before the battery discharges and the closed-circuit voltage after the battery discharges after the battery is detected to meet the set condition, so that the accuracy of the health detection on the battery is improved; meanwhile, after the health detection, a processing action corresponding to the health detection result is required to be executed, so that the processing efficiency of the battery is improved, and the safety of the battery is improved.

In another embodiment of the present application, in order to ensure that the total charging time and the sleep time of the battery respectively satisfy the respective corresponding setting conditions from the end time of the current health detection of the battery to the start time of the next health detection of the battery, so as to improve the detection accuracy of the battery, the terminal device may set the total charging time and the sleep time of the battery to zero after determining the health detection result of the battery according to the health state parameter of the battery and the preset battery health degree table.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
