[0002] As the battery is used for a longer time, it will be affected by high temperature and high pressure, and its life will gradually decrease.

The character " / " indicates that the associated objects before and after are in an "or" relationship.

[0054] The specific implementation modes of the present invention are described in detail below with reference to the accompanying drawings.

[0055] Figure 1 The present invention is a flowchart of a battery charging method according to an exemplary embodiment. The method is applied to a terminal, which may be, for example but not limited to, a mobile terminal such as a smart phone, a tablet computer, a smart TV, a smart watch, a PDA (Personal Digital Assistant), a portable computer, or a smart home device such as a sweeping robot, an air purifier, an air conditioner, a lighting, a speaker, a robot, etc. Figure 1 As shown, the method may include the following steps:

[0056] In step S101, historical charging parameters corresponding to the last charging of the battery of the terminal and battery health parameters of the battery are obtained.

[0057] Among them, the historical charging parameters may include historical cut-off voltage and historical cut-off current. The historical cut-off voltage represents the voltage corresponding to the battery when the last charge was cut off, and the historical cut-off current represents the current corresponding to the battery when the last charge was cut off. The battery health parameter is used to characterize the health status of the battery, for example, it may include SOH (English: state of health; Chinese: battery health, which can be understood as the percentage of the current capacity of the battery to the factory capacity) or the number of battery charge and discharge cycles.

[0058] In step S102, a target cutoff voltage and a target cutoff current corresponding to the battery are determined according to the historical charging parameter and the battery health parameter.

[0059] In this step, the first target capacity of the battery can be determined based on the historical charging parameters. The first target capacity is used to characterize the maximum capacity of the battery in the current state. Then, the target cutoff voltage and target cutoff current are determined based on the historical charging parameters of the battery, the first target capacity, and the battery health parameters.

[0060] In step S103, the battery is controlled to be charged according to the target cut-off voltage and the target cut-off current.

[0061] After determining the target cut-off voltage and target cut-off current, the target cut-off voltage can be sent to the battery's PMIC (Power Management IC). The PMIC controls the battery to stop charging when the charging voltage reaches the target cut-off voltage and the charging current reaches the target cut-off current the next time the battery is charged, so as to maximize the use of the battery capacity, achieve full charging of the battery, and ensure battery life.

[0062] Through the above technical solution, the aging degree of the terminal can be accurately determined based on the historical charging parameters and battery health parameters of the battery. Then, the target cutoff voltage and target cutoff current adapted to the current aging degree are determined in real time according to the aging degree, and the battery is controlled to charge according to the target cutoff voltage and target cutoff current. In this way, the target cutoff voltage and target cutoff current adapted to the current aging degree of the terminal can be determined for different terminals, and the current capacity of the battery can be fully utilized to maximize the battery life.

[0063] The above step S102 is described in detail below. In the above step S102, determining the target cut-off voltage and target cut-off current corresponding to the battery according to the historical charging parameter and the battery health parameter may include the following steps:

[0064] S1, determining a first target capacity of the battery according to the historical cut-off voltage and the historical cut-off current.

[0065] The first target capacity of the battery may be simulated by using a battery power meter.

[0066] For example, the first target capacity of the battery can be determined by performing multiple iterative calculations based on the historical cut-off voltage and the historical cut-off current according to the ampere-hour integration method according to the standard discharge parameters of the battery. The specific calculation method can refer to the relevant implementation method and will not be repeated here.

[0067] It should be noted that the above examples are only for illustration, and other methods of simulating battery capacity through a fuel gauge may also be used, and the present disclosure does not specifically limit this.

[0068] S2, determining the target cut-off voltage and the target cut-off current according to the historical cut-off voltage, the first target capacity and the battery health parameter.

[0069] For example, first, the first target voltage value can be determined according to the battery health parameter and the preset corresponding relationship. Among them, the preset corresponding relationship includes the corresponding relationship between the battery health parameter and the voltage value. For example, taking the battery health parameter including the number of battery charge and discharge cycles as an example, the preset corresponding relationship includes the corresponding relationship between the number of battery charge and discharge cycles and the voltage value. For example, cycle = 100, DV = 15mV; cycle = 300, DV = 20mV; cycle = 800, DV = 30mV. Among them, cycle represents the number of battery charge and discharge cycles, and DV represents the voltage value. If the number of battery charge and discharge cycles of the current battery reaches 100 times, the first target voltage value can be determined to be 15mV according to the preset corresponding relationship. Secondly, the target cut-off voltage can be determined according to the first target voltage value and the historical cut-off voltage. For example, the difference between the historical cut-off voltage and the first target voltage value can be used as the target cut-off voltage. Finally, the target cut-off current can be determined according to the target cut-off voltage and the first target capacity.

[0070] In one possible implementation, determining the target cutoff current according to the target cutoff voltage and the first target capacity may include: simulating charging of the battery according to the target cutoff voltage, and when the capacity of the battery reaches the first target capacity, using the charging current value of the battery as the target cutoff current. In this way, the current maximum capacity of the battery can be fully utilized to ensure that the battery life is maximized. The target cutoff current is obtained through charging simulation, and the battery is controlled to charge according to the target cutoff voltage and the target cutoff current during the next charging, which can ensure that when the battery reaches the target cutoff voltage and the target cutoff current, the charged capacity of the battery can reach the maximum capacity of the battery.

[0071] In another possible implementation, it is considered that if the battery capacity is allowed to reach a saturated state for a long time, the battery life will be affected to a certain extent. Therefore, the difference between the first target capacity and the preset capacity value can also be used as the second target capacity. That is to say, on the basis of the maximum capacity of the battery, a certain margin is left for the battery capacity during charging. Secondly, the battery can be charged according to the target cut-off voltage. When the capacity of the battery reaches the second target capacity, the charging current value of the battery is used as the target cut-off current. In this way, the battery capacity can be utilized as much as possible while ensuring the battery life, thereby ensuring the battery life.

[0072] Figure 2 is a flow chart of another battery charging method according to an exemplary embodiment. Figure 2 As shown, the method may further include the following steps:

[0073] In step S104, the average battery temperature corresponding to the battery in the historical time period is obtained.

[0074] In this embodiment, considering that the operating temperature of the battery in different scenarios is different, if the battery is used at a low temperature for a period of time, it can be considered that the battery is in a good operating environment. Figure 1 The method in the embodiment reduces the charge cut-off voltage, but cannot maximize the performance of the battery. Figure 1 Based on the embodiment, the battery charging cut-off voltage is raised to maximize the performance of the battery, thereby obtaining the target cut-off voltage. If the battery is used at a high temperature for a period of time, it is considered that the battery is used in a poor environment. Figure 1 The method in the embodiment reduces the charging cut-off voltage, ensures the service life of the battery, and then obtains the target cut-off voltage.

[0075] In this step, the average battery temperature corresponding to the battery in the historical time period may be obtained to determine the use environment of the battery in the historical time period. The historical time period may be the time period between the current moment and the set historical moment.

[0076] In step S105 , a second target voltage value is determined according to the average battery temperature.

[0077] For example, the second target voltage value of the battery may be determined based on the average battery temperature and the first preset voltage correspondence relationship, and the first preset voltage correspondence relationship may include, for example, the correspondence relationship between the battery temperature and the voltage value. For another example, the voltage reduction gear of the battery may be determined based on the average battery temperature and the second preset voltage correspondence relationship, and then the second target voltage value may be determined based on the voltage reduction gear, and the second preset voltage correspondence relationship may include, for example, the correspondence relationship between the battery temperature and the voltage reduction gear.

[0078] For example, the second preset voltage correspondence relationship may be shown in the following table:

[0079] T≤25 degrees 25 degrees<T≤35 degrees 35 degrees<T≤40 degrees 40 degrees<T≤45 degrees 0-35h -1 0 0 MAX 35-70h -2 -1 0 +3 70-105h -3 -2 0 +2 105-140h -3 -3 -1 +1 140h+ MIN -3 -2 0

[0080] Among them, the first column represents different historical time periods, for example, it may include 0-35h, 35-70h, 70-105h, 105-140h, 140h+. It should be noted that in actual applications, only one time range can be set, that is, only the average battery temperature in a historical time period is concerned. Multiple time ranges can also be set to focus on the corresponding average battery temperatures in different historical time periods. The first row represents different temperature ranges, for example, it may include T≤25 degrees, 25 degrees<T≤35 degrees, 35 degrees<T≤40 degrees, 40 degrees<T≤45 degrees, and T is the battery temperature. The contents in the second to fifth columns and the second to sixth rows in the table are pre-set step-down gears, such as -3, -2, -1, 0, +1, +2, +3. After determining the step-down gear according to the historical time period and the average battery temperature, the second target voltage value can be determined by n*10mV, where n is the step-down gear.

[0081] For example, if the historical time period is within 70-105h, and the average battery temperature of the battery is within 40 degrees <T≤45 degrees, it can be determined that the current voltage reduction gear is +2, and the second target voltage value of the battery can be +2*10mV, that is, 20mV. If the historical time period is within 35-70h, and the average battery temperature of the battery is within 35 degrees <T≤40 degrees, it can be determined that the current voltage reduction gear is 0, and the second target voltage value of the battery can be 0*10mV, that is, 0mV.

[0082] It should be noted that the above examples are only for illustration and the present disclosure is not limited thereto.

[0083] Further, the above-mentioned determination of the target cutoff voltage according to the first target voltage value and the historical cutoff voltage may include: determining the target cutoff voltage according to the first target voltage value, the second target voltage value and the historical cutoff voltage. For example, the difference between the historical cutoff voltage and the first target voltage value may be determined first, and then the sum of the second target voltage value and the difference may be used as the target cutoff voltage. That is, the target cutoff voltage V=V1-V2+V3, wherein V1 represents the historical cutoff voltage, V2 represents the first target voltage value, and V3 represents the second target voltage value.

[0084] In actual scenarios, the remaining battery power is usually obtained by simulating the fuel gauge. At present, the battery capacity parameters of the battery are needed to simulate and calculate the remaining battery power. As for the battery capacity parameters of the battery, after the terminal leaves the factory, the battery capacity parameters are unchanged, that is, the rated value. However, as the battery continues to age, the actual capacity parameters of the battery gradually decrease, but the battery capacity parameters calibrated in the fuel gauge remain unchanged, which will cause the fuel gauge to fail to report normally, that is, the battery power cannot show a fully charged (i.e., 100%) state. Taking the above problems into consideration, in this embodiment, if Figure 3 As shown, the method may further include the following steps:

[0085] In step S106, the battery capacity parameter corresponding to the power meter of the terminal is updated according to the first target capacity.

[0086] In this way, by updating the corresponding battery capacity parameter in the fuel meter according to the first target capacity, the battery capacity recorded in the fuel meter is the actual capacity of the current battery, so as to ensure that the normal reporting of the fuel meter is not affected.

[0087] Through the above technical solution, the aging degree of the terminal can be accurately determined based on the historical charging parameters and battery health parameters of the battery. Then, the target cutoff voltage and target cutoff current adapted to the current aging degree are determined in real time according to the aging degree, and the battery is controlled to charge according to the target cutoff voltage and target cutoff current. In this way, the target cutoff voltage and target cutoff current adapted to the current aging degree of the terminal can be determined for different terminals, and the current capacity of the battery can be fully utilized to maximize the battery life.
