[0021] Figure 1 The present invention is a schematic flow chart of a charging protection method according to an embodiment of the present invention, and the charging protection method can be executed by a terminal. The terminal includes but is not limited to a communication device such as a mobile phone, a tablet computer, a wearable device, a sensor, and an Internet of Things device.

[0022] like Figure 1 As shown, the charging protection method includes:

[0023] In step S101, the charging current value of the battery is periodically detected;

[0024] In step S102, when the battery meets the current limiting condition, an average value of a first number of historical charging current values ​​recently detected by the battery is determined;

[0025] In step S103, the charging current of the battery is set to be no greater than the average value.

[0026] In some embodiments, the terminal may periodically detect the charging current value of the battery through FCC voting.

[0027] In some embodiments, the terminal may record the detected charging current value.

[0028] The terminal may determine an average value of the first number of historical charging current values ​​according to the recorded charging current values.

[0029] In some embodiments, the historical charging current value recorded by the terminal is not less than a first number and not greater than a second number, wherein the second number is greater than the first number.

[0030] The terminal can erase the historical charging current values ​​that are far away from the current moment according to the timestamp of the recorded charging current value, and record a new charging current value to ensure that the recorded charging current value can meet the requirement of determining the average value of the first number of historical charging current values ​​and is not greater than the second number to avoid wasting storage resources.

[0031] In some embodiments, when the battery meets the current limiting condition, the average value of the first number of historical charging current values ​​recently detected by the battery is determined. When the battery meets the current limiting condition, it means that the charging power needs to be limited.

[0032] The battery charging can include constant current fast charging mode and constant voltage slow charging mode. The terminal can limit the current in the following situations: when switching from constant current fast charging mode to constant voltage slow charging mode; when there is a fault in the battery; when the battery temperature rises too quickly.

[0033] If the current limiting conditions are met, it indicates that the battery does not need to be charged at the current higher power, or that continuing to charge the battery at a higher power will be dangerous. In this case, the charging process can be current limited to avoid battery damage, improve battery durability, and prevent battery aging.

[0034] In some embodiments, the value of the first number may affect the technical effect of current limiting.

[0035] Specifically, if the value of the first number is larger, the impact of the charging current value reduced at the current moment on the average value of the historical charging current values ​​of the first number will be smaller, making the current limiting process smoother but taking longer; if the value of the first number is smaller, the charging current value reduced at the current moment will have a greater impact on the average value of the historical charging current of the first number, resulting in the charging current value decreasing at a faster rate after the current limiting measures are taken. While shortening the current limiting time, it will also cause the charging current value to change more dramatically during the current limiting process, which may cause the wireless charging to be disconnected or repeatedly to a higher charging current value due to the fast charging algorithm.

[0036] In some embodiments, the first number may be thirty.

[0037] In some embodiments, determining the average value of the first number of historical charging current values ​​that are most recently detected by the battery includes: the terminal can determine the arithmetic mean of the FCC vote of the jeita specification (Japan Electronics and Information Technology Industries Association) of the first number of battery detections most recently through FCC voting, as the average value of the first number of historical charging current values ​​that are most recently detected by the battery.

[0038] In some embodiments, the charging current of the battery is set to be no greater than the average value.

[0039] It should be noted that after executing the charging protection method proposed in the present disclosure, each charging current value is based on the average value, and the current charging current value is set to be no greater than the average value.

[0040] Furthermore, since the terminal is still continuously detecting the charging current of the battery, the reduced charging current value will also be counted in the first number of historical charging current values, so that each reduction in the charging current value will reduce the average value of the most recent first number of historical charging current values, and each reduced charging current value has a small impact on the average value, so that the average value will not be reduced too quickly, and each charging current value will not be reduced too much. Therefore, the charging current set to be no greater than the average value can maintain a relatively gentle reduction trend.

[0041] In some embodiments, setting the charging current of the battery to be no greater than the average value includes: setting the current charging current of the battery to the product of the average value and a first coefficient, where the first coefficient is greater than 0 and less than 1.

[0042] The technical effect of the method disclosed herein will be described below with the first coefficient being 0.8.

[0043] In the related technology, current limiting is performed on the basis of the last charging current. Therefore, if the last charging current is 4000mA, after executing the current limiting algorithm, the first charging current drops to 3200mA, the second charging current drops to 2560mA, the third charging current drops to 2048mA, and the fourth charging current drops to 1638.4mA. The current limiting time interval for each charging current is short, resulting in a rapid decrease in the charging current within a short period of time. At this time, other charging algorithms of the terminal may be triggered. Based on the incomplete battery capacity, the low charging current is corrected and raised to 4000mA again, completing a charging current fluctuation.

[0044] In the present disclosure, the first number is 30 as an example. Since the battery is in constant current charging before the current limiting algorithm is executed, the charging current values ​​for 30 times are all 4000mA, and the average value is also 4000mA. At this time, the first current limiting reduces the charging current to 3200mA. When the current limiting operation is performed for the second time, since it is necessary to determine the average value of the charging currents of the first 30 times, the new charging current of 3200mA replaces the earliest charging current of 4000mA, so that the average value becomes (29×4000mA+3200mA) / 30=3973mA. Therefore, the second current limiting reduces the charging current to 3973mA×0.8=3178mA. Similarly, during the third current limiting, the average value of the charging currents of the first 30 times is (28×4000mA+3200mA+3178mA) / 30=3946mA, and the charging current for the third time is reduced to 3946mA×0.8=3157mA.

[0045] Without using the charging protection method disclosed in the present invention, the current limiting of the charging current is reduced from 4000mA to 3200mA and 2560mA, while with the method disclosed in the present invention, the current limiting of the charging current is reduced from 4000mA to 3200mA, 3178mA and 3157mA.

[0046] Figure 2 FIG. 1 is a schematic diagram showing a comparison of the effects of a charging protection method according to an embodiment of the present disclosure. Figure 2 As shown, Figure 2 The dashed box in the figure is the current limiting process of the charging current during the charging process. The charging protection method disclosed in the present invention can make the current limiting process of the charging current smoother, avoid the problem of wireless charging interruption caused by the rapid decrease of the charging current, and the repeated fluctuation of the charging current, thereby improving the durability of the battery and avoiding battery aging.

[0047] The charging protection method proposed in the present invention achieves smooth current limiting of the charging current by determining the average value of the first number of historical charging current values ​​recently detected by the battery, and sets a charging current not greater than the average value based on the average value, thereby avoiding fluctuations in the charging current. When the battery meets the current limiting conditions, the charging power is reduced, the battery aging is slowed down, and the durability of the battery is improved.

[0048] In some embodiments, the detected charging current value may be stored in the form of a circle queue.

[0049] When the terminal enters the charging state, the circular queue structure can be cleared, and the size (size) of the circular queue structure is specified according to the value of the first quantity, and is smaller than the maximum value (Max Size) of the circular queue structure.

[0050] Figure 3 FIG. 1 is a schematic diagram of a method for storing a charging current value according to an embodiment of the present disclosure. Figure 3 As shown, in the circular queue 301, a head pointer 303 and a tail pointer 302 are included, which are used to indicate the head and tail of the historical charging current value 304 stored in the circular queue. The historical charging current value 304 is stored between the head pointer 303 and the tail pointer 302, wherein each black square indicates that a historical charging current value is stored, and the circular queue in the figure stores 36 historical charging current values.

[0051] Whenever the terminal detects a new charging current value, the newly detected charging current value can be stored in the memory space pointed to by the head pointer. The head pointer 303 will Figure 3 If the number of historical charging current values ​​304 stored in the circular queue exceeds the set size, the tail pointer 302 will also move one grid to the right to eliminate the charging current value stored in the memory space pointed to by the tail pointer 302; if the head pointer 303 coincides with the tail pointer 302, the tail pointer 302 will also move one grid to the right.

[0052] In some embodiments, the method further includes: determining status information of the battery; and judging whether the battery meets the current limiting condition according to the status information.

[0053] The current limiting condition may include the conversion stage of the charging mode of the battery during the normal charging process. For example, the conversion from the constant current fast charging mode to the constant voltage slow charging mode. It may also include the battery being in an abnormal state. In an abnormal state, current limiting is used to avoid further damage to the battery due to excessive charging power, thereby improving battery durability.

[0054] Figure 4 It is a schematic flow chart of a charging protection method according to an embodiment of the present disclosure.

[0055] In some embodiments, determining the status information of the battery includes:

[0056] In step 401, a preset register on the battery management module is read to obtain the status information of the battery; wherein the status information of the battery is written into the preset register after the firmware burned on the battery management module detects the status of the battery.

[0057] like Figure 4 As shown, the process of calling the charging protection method disclosed in the present invention is as follows:

[0058] In step 400, the terminal can determine whether it is in a charging state. If it is not in a charging state, the process ends. If it is in a charging state, the battery detection task can be started and step 401 is executed to achieve periodic detection of the battery status.

[0059] In step 401, a preset register on the battery management module 410 can be read to obtain battery status information; wherein, the terminal can periodically read the preset register through the IIC bus (Inter-Integrated Circuit) protocol, and the preset register includes at least one of the following: an internal short circuit (ISC) register and a safe operating area (SOA) register; ISC can be used to determine the short circuit condition inside the battery, and SOA can be used to determine whether the temperature change rate of the battery exceeds a preset value.

[0060] In step 402, it is determined whether the preset register on the battery is set, that is, whether the content stored in the register is changed; if there is no change, the battery is continuously detected and step 401 is executed; if the register is set, step 403 is executed;

[0061] In step 403, the charging protection method is called, that is, the charging protection method proposed in the present disclosure is executed, and when it is determined according to the battery status information that the battery meets the current limiting condition, the current limiting method is executed.

[0062] In the above process, the battery status information is written into the preset register by the battery management module 410. The battery management module 410 is described below:

[0063] The battery management module 410 includes a burned firmware; the firmware can periodically execute step 411 to detect the status information of the wire transfer in real time, and execute step 412 to update the preset register according to the current status information of the battery.

[0064] The battery management module can thus update a preset register according to the current status information of the battery, and provide the status information in the preset register to the terminal in step 401 .

[0065] By detecting the battery, the terminal can determine whether there are any hardware abnormalities in the battery during charging, and can detect changes in battery materials caused by the battery in some application scenarios, such as slight drops of the terminal, natural aging, high temperature environments, long-term use, etc. These scenarios will cause the materials inside the battery to change to varying degrees.

[0066] However, if a high-power charging method is still used when the internal materials of the battery have changed and there may be abnormalities, it may cause the battery to age faster, reduce durability, or even be damaged. In severe cases, the battery may burn or explode. Therefore, when the present invention determines that the terminal battery has a hardware abnormality and meets the current limiting conditions, it reduces the charging current and the charging power, thereby improving the battery durability.

[0067] In some embodiments, the status information includes at least one of the following: internal short-circuit current of the battery; and temperature information of the battery.

[0068] The internal short-circuit current of the battery can be determined by reading the status information of the ISC register, and the temperature information of the battery can be determined by reading the status information of the SOA register.

[0069] In some embodiments, judging whether the battery meets the current limiting condition based on the status information includes at least one of the following: judging whether there is a short circuit in the battery based on the internal short-circuit current; judging whether the temperature change rate of the battery is greater than a first threshold value based on the temperature information.

[0070] For example, the short circuit level can be set according to the value of the internal short circuit circuit, and the higher the short circuit level, the more serious the internal short circuit of the battery. When the internal short circuit current of the battery reaches the set short circuit level, it is determined that the battery meets the current limiting condition.

[0071] For example, the temperature of the battery can be determined based on the temperature information, and when the battery temperature is greater than a temperature threshold, it is determined that the battery is in a high temperature environment and meets the current limiting condition.

[0072] For example, based on the temperature information, it can be determined whether the temperature change rate of the battery is greater than the first threshold. When the temperature change rate is greater than the first threshold, it is determined that the terminal battery may be heating up too quickly due to hardware abnormalities or the external usage environment. It is then determined that the current limiting conditions are met and the charging current needs to be reduced to reduce the charging power, thereby avoiding battery aging problems caused by rapid heating and improving battery durability.

[0073] In some embodiments, the method further includes: determining a charging voltage of the battery in a constant voltage charging state, the charging voltage being less than a floating voltage of the battery; and charging the battery in the constant voltage charging state according to the determined charging voltage.

[0074] Generally speaking, the floating voltage of a battery is the maximum voltage that the battery reaches when fully charged, and is also the charging voltage during constant voltage charging. However, in order to speed up the charging process, some manufacturers increase the floating voltage to charge the battery with a higher voltage, which may cause oversaturation of charging.

[0075] For example, the full-charge voltage of the battery is 4.5V, and some fast-charging algorithms will use a floating voltage of 4.53V to charge the battery. However, the present disclosure controls the charging voltage to be lower than the floating voltage of the battery to avoid over-saturation of the battery and affect the battery life.

[0076] In some embodiments, controlling the charging voltage to be less than the floating voltage of the battery includes: the charging voltage value is the difference between the floating voltage value and a preset reduction; and / or the charging voltage value is the product of the floating voltage value and a second coefficient, and the second coefficient is greater than 0 and less than 1.

[0077] If the preset reduction is too large, it will greatly affect the speed at which the battery is fully charged under constant voltage charging. If the preset reduction is too small, it cannot prevent oversaturation charging. Therefore, the specific preset reduction can be measured in the laboratory, and different batteries and terminals can also use different preset reductions.

[0078] In some embodiments, the preset reduction amplitude may be 15 mV.

[0079] For the above-mentioned battery with a full-charge voltage of 4.5V, the floating voltage based on the fast charging algorithm is 4.53V. The preset reduction can be determined as 15mV based on the laboratory test results, that is, the constant-voltage charging voltage determined by the present disclosure for the battery can be 4.515V, which can avoid over-saturation while ensuring charging efficiency.

[0080] In some embodiments, the preset reduction rate can be adjusted according to the user's usage habits.

[0081] For example, based on the usage habits of a certain user, it is determined that it takes a total of 3 hours for the user's terminal to enter the constant-voltage charging process and disconnect from the charger to end charging, and the battery of the terminal reaches the full charging voltage for the first time after 1 hour of constant-voltage charging. The preset reduction rate can be adjusted so that the terminal reaches the full charging voltage for the first time after 3 hours of the constant-voltage charging process, which is in line with the user's usage habits and avoids oversaturation of the battery.

[0082] In some embodiments, setting the charging current of the battery to be no greater than the average value includes: when the voltage of the battery is less than the fast charge cut-off voltage and / or the battery is in a non-constant voltage charging mode, setting the charging current of the battery to be no greater than the average value.

[0083] When the battery voltage reaches the fast charge cut-off voltage, the battery is about to be fully charged. At this time, the battery will generally adjust the charging strategy, not use a large current for charging, and adopt a certain degree of current limiting. Therefore, the battery protection method of the present invention may not be executed; similarly, when the battery is in a constant voltage charging mode, the voltage is constant, and as the battery capacity increases, the charging current will gradually decrease. At this time, there is no problem of high charging power due to a large charging current, and the battery life and durability will not be affected.

[0084] Therefore, when the battery voltage is lower than the fast charge cut-off voltage, and / or the battery is in a non-constant voltage charging mode, it means that the terminal will execute a fast charge strategy, using a larger current and a larger charging power to charge the battery. This, combined with a hardware failure in the battery, may lead to serious consequences such as reduced battery life and durability.

[0085] In some embodiments, the method also includes: when the voltage of the terminal battery is less than the fast charging cut-off voltage and the battery is in a non-constant voltage charging mode, when it is determined according to the battery status information that the current limiting condition is met, executing a current limiting and voltage reduction method to achieve charging protection for the battery.
