Detailed Description
The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following description will be made of related technologies related to the embodiments of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a wireless headset provided in the related art. The wireless headset 100 includes two wireless earpieces 110 and a headset charging box 120. Each wireless receiver 110 is provided with three metal pins 111, each wireless receiver has only two pins, the earphone charging box 120 is provided with three pogo pins 121 corresponding to the metal pins 111, and some corresponding wireless earphones have only two corresponding pogo pins. The two Wireless earpieces 110 can independently operate without cable connection by realizing Wireless separation of left and right channels, i.e., tws (true Wireless stereo) headphones. The headset charging box 120 has integrated therein a mobile power supply for charging the wireless handset 110 and a power management chip.
Due to the supply of batteries, batteries used in the same location in electronic devices are sometimes supplied by two or more battery manufacturers. For batteries of different models, the battery core, the internal resistance and the like of the batteries are different, so that the charging and discharging characteristics are different, and therefore, the batteries currently used on the electronic equipment need to be identified in order to be compatible with the batteries of different models. At present, a common battery identification method is to perform hardware identification on a battery, for example, one pin is added, and the identification is supplemented by configuring different resistors, so that two battery wires are changed into three battery wires, and one pin is used for identifying the type of the battery. The power management chip judges the specific type of the battery by acquiring the level of the battery type identification pin.
In summary, in the related art, the electronic device needs to be configured with an additional battery model identification pin for battery identification, which causes several problems:
1. the structure becomes complicated. For small products such as earphones and the like, the space is extremely limited, and a pin and a line are added, so that troubles are brought to layout and the like.
2. It becomes troublesome in operation. A wire is added, so that a welding point is added, and troubles in production and the like can be brought.
3. The complexity of the electronic design. Because a pin is needed to identify the battery model, an additional pin of the main control is needed, and the electronic design becomes complicated.
4. The cost increases, and the increase in the wire and the welding process brings about an increase in the cost.
Based on this, the following technical scheme of the embodiment of the application is provided, the battery is sampled at least twice, and at least one sampling is required to be carried out at the constant current charging or constant current discharging stage, so that corresponding sampling values are obtained, the sampling values comprise sampling voltage values, the sampling values reflect the electrical characteristics of the battery, and because the electrical characteristics of different batteries are different, the battery can be accurately identified according to all or part of the sampling values obtained by sampling. Therefore, the battery can be identified without arranging a special identification pin, and the effects of reducing the complexity of the electronic equipment and further reducing the cost are achieved.
The following describes the execution steps of the battery identification method, and fig. 2 is a schematic flowchart of the battery identification method provided in the embodiment of the present application, and as shown in fig. 2, the flowchart includes the following steps:
step 201: sampling the battery at least twice; wherein the at least two samples comprise at least one first sample; the first sampling is used for representing sampling occurring when the battery is in a constant current stage; the constant current stage comprises: a constant current charging phase or a constant current discharging phase.
Step 202: determining the characteristics of the battery according to the sampling value of all or part of the at least two samplings; wherein the sampling value comprises: a voltage value of the battery.
The main execution body of the above steps is an equipment carrier of a power management chip, and the equipment carrier can be electronic equipment such as a mobile phone, an intelligent household appliance or an intelligent wearable assembly, but is not limited thereto. It should be noted that, for the wireless headset, both the wireless headset and the headset charging box can be used as the execution main body of the above steps. For convenience of description, the execution main body is hereinafter represented as an electronic device on which a power management chip is provided.
A Power Management chip (Power Management Integrated Circuits) is a chip that plays roles in converting, distributing, detecting, and other Power Management functions in an electronic device system. The CPU power supply amplitude is mainly identified, corresponding short moment waves are generated, and a post-stage circuit is pushed to output power.
Referring to fig. 3, a charging method of a battery is described, as shown in fig. 3, in the related art, the charging of a lithium battery is divided into three stages: a pre-charging stage, a constant current stage and a constant voltage stage. The charge and discharge current is generally referred to as C, which is a numerical value corresponding to the battery capacity. The battery capacity is generally expressed by Ah and mAh, for example, the battery capacity of a battery is 1200mAh, and the corresponding C is 1200 mA. Taking a 4.2V battery as an example, the voltage of the battery to be charged should be detected first when charging is started, if the voltage is lower than 3V, the pre-charging stage is to be entered first, the charging current is 1/10 of the set current, the set current is generally set between 0.2C and 1C, and is generally selected to be about 0.05C. After the voltage rises to 3V, the standard charging process is entered. The standard charging process is: the constant current stage is firstly entered to charge the battery by the set current, and when the voltage of the battery rises to 4.20V, the constant voltage stage is entered to charge the battery by the constant voltage, and the charging voltage is kept to be 4.20V. At this time, the charging current gradually decreases, and when the current decreases to 1/10 of the set charging current, the charging ends.
In step 201, the electronic device samples the battery at least twice and obtains corresponding sample values. Here, the sample value includes: the voltage value of the battery. In addition to this, the sampling values may additionally comprise sampling instants
It should be noted that the at least two sampling operations include at least one first sampling operation, where the first sampling operation is performed when the battery is in the constant current phase. The constant current stage comprises: a constant current charging phase or a constant current discharging phase. It should be noted that, when the battery is in the constant current phase, the sampled voltage values at different sampling moments may be different. In addition, if the battery is in different charge and discharge stages at different sampling times, the voltage of the battery should also be different. Therefore, at least one first sampling is required to be included in at least two sampling, so that different sampling voltage values can be obtained by the electronic equipment through at least two sampling for the battery, and in addition, the characteristics that the corresponding battery voltage values of the batteries of different types are different in the charging and discharging processes or the battery voltage value change conditions are different are adopted, so that the battery identification cost can be reduced by utilizing the characteristics to identify the batteries of different types.
It will be appreciated that the purpose of obtaining sampled values is to obtain electrical characteristics of the sampled battery, and therefore, to obtain more accurate electrical characteristics of the battery, in some possible embodiments, each sample of the battery may last for a certain time, for example 10ms, to exclude signal interference that may occur. In practical applications, the battery under constant current discharge may be a condition that the battery load is substantially stable, and even if the discharge current slightly fluctuates, the battery is considered to be in a constant current discharge phase.
In practical applications, according to the different phase of the previous sampling of at least two sampling, step 201 can be divided into the following three execution modes:
the first method is as follows: and carrying out at least two times of first sampling on the battery.
The second method comprises the following steps: performing at least one second sampling on the battery; wherein the second sample is used to characterize the sample that occurred when the battery was in an open circuit condition.
And when the battery enters a constant current stage from an open circuit, performing at least one time of first sampling on the battery.
The third method comprises the following steps: performing at least one third sampling on the battery; wherein the third sample is used to characterize the sample that occurred if the battery was in a pre-charge phase.
And when the battery enters a constant current charging stage from a pre-charging stage, performing at least one time of first sampling on the battery.
The above three ways can exist in combination without conflict, and the final battery characteristic can be determined according to the battery characteristics determined in various ways.
In the first mode, at least two times of sampling of the battery by the electronic device occur in the constant current charging or constant current discharging stage.
In practical applications, the first mode can be further defined as:
performing at least two times of first sampling on the battery within a set sampling interval in a constant current stage; the set sampling interval comprises a set time interval or a set voltage interval.
It should be noted that, there is a characteristic difference in the constant current stage between batteries of different models, and the set sampling interval may be a voltage interval in which the characteristic difference between batteries is most obvious. The battery can be identified more accurately by the sampling value obtained by sampling in the set sampling interval.
It should be further noted that, the electronic device may perform the first sampling on the battery for the second time in a set time length after the first sampling, so as to obtain the current voltage value of the battery. If the set sampling interval is the set time interval, the set time interval can be used for indirectly ensuring that at least two times of sampling of the battery by the electronic equipment are in a voltage interval with the most obvious difference characteristic of the battery, and can also be used for ensuring that at least two times of sampling are still in a constant current stage and do not enter a constant voltage stage. Since the pressure value of the battery will remain unchanged if the battery enters the constant voltage stage, the electrical characteristics of the battery may not be accurately obtained. For example, the set time interval may be 5 minutes.
It should be understood that, in practical application, the set sampling interval may be matched with calibration characteristic parameters of batteries of different types pre-stored in the electronic device, so as to reduce the difficulty in determining the battery type. The characteristic parameters of the battery calibration can be provided by a battery manufacturer or can be measured according to experiments.
In the second mode, the electronic device firstly performs at least one second sampling on the battery in the open circuit state, and performs at least one first sampling on the battery after the battery enters the constant current stage from the open circuit state.
It will be appreciated that the purpose of the electronics to perform at least one second sampling of the battery in the open circuit state is to obtain a raw voltage of the battery, which is the open circuit voltage of the battery before it enters the constant current phase. For example, before the electronic device is connected to a charger to perform constant current charging on a battery, the open-circuit voltage of the battery is collected, and the open-circuit voltage is the original voltage. For another example, before the electronic device is connected to a load for constant current discharge, the open-circuit voltage of the battery is collected, and the open-circuit voltage is the original voltage. It is easy to understand that before the battery enters the constant current phase, the electronic device may perform voltage acquisition on the battery at set time intervals, for example, perform voltage acquisition on the battery at 5s intervals, and when the electronic device detects that the charger is connected or constant current discharge is entered, the last previous acquired voltage value is taken as the original voltage.
In practical applications, the original voltage acquired by the electronic device may be limited within a set range, where the set range is used to ensure that the battery is in a constant current stage when the battery is charged or discharged with the original voltage as an initial value.
It should be noted that, in practical application, the charger may be plugged and then pre-charged first and then enter the constant current charging, so that the method is not limited to performing at least one first sampling on the battery after the battery enters the constant current phase from the open circuit, or performing at least one first sampling on the battery after the battery enters the pre-charged phase and then enters the constant current phase from the open circuit, and both of the method and the device belong to the case where the electronic device performs at least two samplings on the battery.
In the third mode, the electronic device performs at least one third sampling on the battery in the pre-charging stage, and performs at least one first sampling on the battery in the constant current stage after the battery enters the constant current stage from the pre-charging stage.
In step 202, the electronic device determines the characteristics of the battery based on the sampled values of all or a portion of the total samples taken in step 201.
It should be noted that the sampled values of all samples performed in step 201 are not necessarily used to determine the model of the battery in step 202. It will be readily appreciated that after some of the samples have been taken to determine the characteristics of the battery, no further samples need to be used. Alternatively, when the specific characteristics of the battery cannot be distinguished by using some of the sampling values, the further determination is performed by using other sampling values in step 201.
In some possible embodiments, step 202 is subdivided into the following steps:
matching sampling results corresponding to sampling values of all or part of the at least two samplings in at least one group of calibrated characteristic parameters to obtain matching results;
determining the characteristics of the battery according to the matching result; wherein,
each set of characteristic parameters in the at least one set of calibrated characteristic parameters corresponds to the characteristics of at least one battery; the calibration samples of the battery characterized by the corresponding characteristic.
It should be noted that, when the sampling result obtained by the battery identification method is compared and matched with the calibration sampling result stored in the electronic device, the sampling result should be matched according to the actual situation, so as to improve the matching precision and facilitate the identification of the battery. Here, there are many fitting methods available in the prior art, such as interpolation, and the like, which are not described herein in detail.
It should be further noted that the matching of the sampling result in at least one set of calibrated characteristic parameters may be performed by:
mode A: and determining the sampling value of all or part of the at least two sampling as the sampling result, and matching the sampling result in at least one set of calibrated characteristic parameters.
Mode B: calculating the sampling result according to the sampling value of all or part of the at least two samplings, and matching the sampling result in at least one group of calibrated characteristic parameters;
wherein,
the sampling result comprises at least one of the following:
a rate of change of voltage of the battery;
the voltage of the battery changes acceleration.
In mode a, the electronics directly match the sampled values of all samples taken in step 201 to at least one set of calibrated characteristic parameters. Here, the at least one set of calibrated characteristic parameters may be used to characterize the correspondence between the duration and the voltage of the at least one battery during the constant current phase. In practical applications, the characteristic parameters are stored in the electronic device in advance.
This example is further illustrated below in conjunction with tables 1, 2 and 3.
Table 1 shows an example of a characteristic parameter calibration table provided in this embodiment of the present application, where the table entries include an exemplary original voltage V1 of batteries of different models, a charging current, a long-time sampling voltage V2 when the battery is in a constant-current charging stage setting, and a floating voltage (i.e., V2-V1) of the battery.
TABLE 1
It should be noted that, after the batteries of different models are charged by the constant current for the same set time, the sampled voltage V2 may be different. In table 1, in the case that the original voltage V1 (for example, the voltage collected when the battery is not charged) is the same, V2 of the battery 1 is 4.05V, and V2 of the battery 2 is 3.95V, which are obviously different from each other, so that V2 and the floating pressure can be used as the first characteristic parameters for matching the sampling results to determine the characteristics of the battery.
TABLE 2
Table 2 shows an example of another characteristic parameter calibration table provided in this embodiment of the present application, where the table entries include an exemplary original voltage V3 (voltage collected when not discharged), a discharge current, a long-time sampling voltage V4 when in a constant-current discharge stage setting, and a voltage drop (i.e., V3-V4) of batteries of different types.
It should be noted that, after the batteries of different types are discharged at the constant current for the same set time, the sampling voltage V4 may be different. In table 2, in the case that the original voltage V3 is the same, V4 of battery 1 is 3.75V, and V4 of battery 2 is 3.70V, which are different from each other, so V4 and the voltage drop can be used as calibrated characteristic parameters for matching the sampling results to determine the characteristics of the battery.
Table 3 shows an example of another characteristic parameter calibration table provided in this embodiment, where the table entry includes durations and corresponding voltage values of batteries of different types in the constant current charging stage.
It is easy to see that the battery 1 is relatively slow to rise between 3.4 and 3.6V and relatively fast to rise between 3.6 and 4.0V, namely the energy density of the battery is relatively high between 3.4 and 3.6V and relatively low between 3.6 and 4.0V; the battery 2 rises faster between 3.4V and 3.8V and rises faster between 3.8V and 4.0V, namely, the energy density of the battery is lower between 3.4V and 3.8V and higher between 3.8V and 4.0V. The batteries of different manufacturers can be identified by using the charging difference of the battery 1 and the battery 2 at 3.4-3.6V and 3.8-4.0V.
In practical application, table 3 may be used to correspond to the first method in step 201, and in the case of constant current discharge, the characteristics of the battery are determined according to the matching relationship between the sampling values of all or part of the first samples and table 3.
TABLE 3
| Duration of constant current charging | Battery 1 | Battery 2 |
| 0min | 3.4V | 3.4V |
| 3min | 3.48V | 3.55V |
| 6min | 3.55V | 3.7V |
| 9min | 3.6V | 3.8V |
| 12min | 3.75V | 3.88V |
| 15min | 3.9V | 3.95V |
| 18min | 4.0V | 4.0V |
In the mode B, the electronic device calculates a corresponding sampling result according to the sampling value sampled in step 201, and then matches the sampling result in at least one set of corresponding calibrated characteristic parameters, where the characteristic parameters may be used to characterize the time-varying characteristic of the voltage of the battery in the constant current stage. In practical applications, the characteristic parameters are stored in the electronic device in advance.
It should be noted that the sampling result includes at least one of the following:
a rate of change of voltage of the battery;
the voltage of the battery changes acceleration.
Specifically, for the condition that the sampling characteristic is the battery voltage change rate, the electronic device performs one derivation on the duration of the battery in the constant current stage by using the voltage value according to the sampling value obtained by at least two times of sampling to obtain the battery voltage change rate. And aiming at the condition that the sampling characteristic is the voltage change acceleration of the battery, the electronic equipment performs secondary derivation on the duration of the constant current stage of the battery by using the voltage value according to the sampling value obtained by sampling at least three times to obtain the voltage change acceleration of the battery.
It is easy to understand that the voltage change rate or the voltage change acceleration of the charge-discharge curves of batteries of different types at certain stages are obviously different, so that the specific type of the battery can be determined by firstly calculating the sampling result of the battery according to the sampling value and then matching the sampling result with the prestored characteristic parameters of the voltage change of the batteries of different types along with the time at the constant current stage.
In some possible embodiments, the determining the characteristic of the battery comprises: determining a charge characteristic of the battery; wherein the electrical quantity characteristic comprises at least one of:
a charging curve;
