[0026] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] Figure 1 This is a schematic diagram of a battery charging method according to an embodiment of the present invention; please refer to Figure 1 .

[0028] On one hand, an embodiment of the present invention provides a battery charging method, which is applied to an electronic device, wherein a battery is provided in the electronic device, and the method comprises: step 101, obtaining power information of the battery; step 102, when the power information satisfies a specified power, obtaining first demand information, the first demand information comprising a first charging current and a first charging cycle corresponding to the first charging current; the first demand information also comprising a second charging current and a second charging cycle corresponding to the second charging current; step 103, alternately charging the battery with a first charging current of the first charging cycle and a second charging current of the second charging cycle; wherein the second charging current is not less than 0, and the second charging current is less than the first charging current.

[0029] A battery charging method is provided in an embodiment of the present invention. After obtaining the power of the battery, when the power of the battery meets the specified power, the method charges the battery alternately through a first charging current in a first charging cycle and a second charging current in a second charging cycle, thereby realizing pulse charging without installing other hardware modules, reducing the polarization reaction in the battery and increasing the service life of the battery.

[0030] In step 101, the battery refers to a small device that can generate electrical energy. Specifically, it can refer to a single battery or a battery pack that integrates multiple functions. Preferably, the battery is a lithium battery; the power information at least includes the current power information of the battery. The power information is obtained by testing the battery according to a detection component connected to the battery, and the battery information is obtained; the detection component can be integrated in the battery or arranged outside the battery.

[0031] In step 102, the power information meets the specified power, which means that the current power of the battery is equal to or higher than the specified power, wherein the specified power is preset by the staff, and specifically, the specified power can be the conversion point between the constant current stage and the constant voltage stage during the battery charging process. Wherein, the first demand information refers to the charging demand of the battery when the battery reaches the specified power; the first demand information can be pre-burned in the battery, and the first demand information is obtained after being read by the embedded controller EC; the charger is notified to charge the battery through the first demand information. The first demand information includes a first charging current and a first charging cycle corresponding to the first charging current; the first demand information also includes a second charging current and a second charging cycle corresponding to the second charging current; wherein, the first charging current and the second charging current refer to the currents used by the charger to charge the battery, the first charging cycle refers to the time corresponding to a cycle charging with the first charging current, and the second charging cycle refers to the time corresponding to a cycle charging with the second charging current, wherein the first charging cycle refers to the time corresponding to a cycle charging with the first charging current, wherein the first charging cycle is 10-20s, and the second charging cycle is 0.5-1s.

[0032] In step 103, the first charging cycle is charged with the first charging current. After the first charging cycle is over, the second charging cycle is charged with the second charging current. The battery is charged with the first charging cycle and the second charging cycle as a large cycle until the charging is completed, wherein the first charging current may be greater than 0, the second charging current may not be less than 0, and the second charging current may be less than the first charging current. Among them, the second charging current may preferably be 0. When the second charging current is 0, pulse charging can be achieved by controlling the power on and off of the charger, so that it is suitable for various environments, and reduces the temperature rise of the battery during the charging process, thereby improving the battery life. Furthermore, when the second charging current is 0, the battery can be discharged for a short time, thereby quickly eliminating the polarization voltage and improving the charging efficiency of the battery.

[0033] A specific embodiment is provided. When the specified power is 70% of the power, and the power information of the current power obtained is greater than or equal to 70%, it is determined that the current power meets the specified power, and the battery is charged according to the charging demand corresponding to the first demand information.

[0034] Figure 2 This is a schematic diagram of a third current charging process of a battery charging method according to an embodiment of the present invention; please refer to Figure 2 .

[0035] In one embodiment, after obtaining the battery power information in step 101, the method includes: step 201, when the power information does not meet the specified power, obtaining second demand information, the second demand information including a third charging current; step 202, charging the battery according to the third charging current so that the battery power information meets the specified power.

[0036] In steps 201-202, when the power information obtained does not meet the specified power, the second demand information is obtained. The second demand information is obtained by burning in the battery and reading through the embedded controller EC to obtain the first demand information; the second demand information includes a third charging current, that is, the constant current section corresponding to the battery charging process. The battery is charged by the third charging current to charge the battery to meet the specified power, so that the battery charging enters pulse charging, thereby eliminating the internal polarization of the battery and improving the service life of the battery. Specifically, in the process of charging the battery, the battery power information obtained is 5%, and it is determined that the power information is lower than the specified power, and the battery is charged according to the charging demand corresponding to the second demand information. Among them, the third charging current can be the same as the second charging current, or it can be different from the second charging current.

[0037] Figure 3 This is a schematic diagram of a battery charging method for obtaining power information according to an embodiment of the present invention; please refer to Figure 3 .

[0038] In one embodiment, the battery is provided with a detection component, and the detection component is used to detect the battery information of the battery; accordingly, before step 101, obtaining the battery power information of the battery, the method includes: step 301, obtaining the battery information of the battery according to the detection component, and the battery information includes at least voltage information and current information; step 302, determining the impedance information of the battery according to the voltage information and the current information; step 303, obtaining the power information corresponding to the impedance information according to the impedance information.

[0039] In steps 301-303, the battery information of the battery is obtained through the detection component, wherein the battery information includes at least voltage information and current information, wherein the voltage information refers to the voltage data of the battery during detection, and the current information refers to the current data of the battery during detection. Specifically, it can be a real-time detection, and the impedance calculation is performed by the detected voltage data and current data to obtain the current impedance information of the battery, and the impedance tracking is performed according to the current impedance information of the battery to fit the current battery power. That is, the impedance curve is obtained by different impedances corresponding to different power, and the current power is obtained by reversely deducing the power according to the impedance calculated according to the voltage data and the current data, so that the power information can be accurately judged, so that when the battery enters the constant voltage section, the battery is charged according to the first demand information to eliminate the polarization phenomenon.

[0040] Figure 4 This is a schematic diagram of a designated power determination process of a battery charging method according to an embodiment of the present invention; please refer to Figure 4 .

[0041] In one embodiment, in step 102, when the power information meets the specified power, the first demand information is obtained, including: step 401, obtaining the constant current information and constant voltage information of the battery; step 402, determining the specified power according to the constant current information and the constant voltage information; wherein the constant current information is the information corresponding to the constant current state of the battery during the charging process; the constant voltage information is the information corresponding to the constant voltage state of the battery during the charging process.

[0042] In steps 401-402, the battery charging process often includes three stages: pre-charging, constant current and constant voltage. The conversion point between the constant current and constant voltage stages is called the CV point, and the specified power can be determined according to the power at the CV point. The cumulative degree of polarization reaction of the battery affects the charging efficiency, which mainly occurs in the constant voltage stage, and is also the main reason for the low charging efficiency in the constant voltage stage. By determining the CV point, when charging enters the constant voltage stage, the first charging current and the second charging current are immediately used to perform alternating charging according to the first charging cycle and the second charging cycle to achieve pulse charging, eliminate the polarization reaction in the constant voltage stage, and improve the charging efficiency.

[0043] Specifically, by obtaining constant current information and constant voltage information, the constant current information and constant voltage information can be pre-entered in the battery; wherein the constant voltage information and constant current information are determined according to the performance of the battery itself. The specific constant current information may refer to the battery power information corresponding to the constant current state of the battery during the charging process; similarly, the specific constant voltage information may refer to the battery power information corresponding to the constant voltage state of the battery during the charging process, for example: when the battery is in the state of 0%-70% power, the battery is in the constant current charging stage; the battery is in the constant voltage charging stage at 70%-100%; then according to the above information, it can be determined that the conversion point is 70%, and the corresponding specified power is 70%. The conversion point judgment of the constant current and constant voltage stages is converted into the question of whether the power meets the specified power, so that it is easier to judge the stage of pulse charging, realize the charging of the battery in the constant voltage stage, and improve the charging efficiency.

[0044] Figure 5 This is a schematic diagram of a setting information confirmation process of a battery charging method according to an embodiment of the present invention; please refer to Figure 5 .

[0045] In one embodiment, in step 103, after charging the battery according to the first demand information, the following steps are included: step 501, when the battery is fully charged, the battery generates setting information, the setting information is used to indicate that the battery is fully charged; step 502, generating a second working instruction according to the setting information, the second working instruction is used to instruct the charger to stop charging the battery.

[0046] In steps 501-502, when the battery is fully charged, there is a specific position in the battery for storing the setting information. When the information corresponding to the position is the setting information, it indicates that the battery is fully charged and the pulse charging is terminated; by generating a second working instruction, the charger connected to the battery is instructed to stop charging the battery. When it is detected that there is no setting information in the specific position, the battery continues to be charged through the first charging requirement or the second charging requirement to increase the battery power.

Detect the current voltage and current of the battery through a detection device, specifically, detect the battery through a voltage detection unit and a current detection unit in the detection device battery; determine the current impedance of the battery according to the voltage and current, and obtain the current battery power according to the impedance tracking method. Read the charging requirements burned into the battery; wherein the charging requirements can be obtained after the embedded controller reads the battery through the system management bus SMBus, assuming that the charging current determined according to the battery is 1C; determine whether the current battery power information meets 70% (the specified power preset according to the characteristics of the battery); if the current battery power does not meet 70%, continue to charge the battery through a 1C current; if the current battery power meets 70%, charge the battery with a 1C current for 10-20s, and charge the battery with a 0 current for 0.5-1s. If the current battery charge reaches 100%, the specific position is set to obtain the setting information, and the charger stops charging the battery. Specifically, the embedded controller EC sends a stop working instruction to the charger to stop charging. At this time, the system enters a short discharge mode, which can quickly eliminate the polarization voltage inside the battery and improve the charging efficiency of the battery. Among them, the specific position is Fullchargebit. If the current battery charge information does not reach 100%, the battery is charged with a current of 1C for 10-20s and a current of 0 for 0.5-1s.
