detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings.

The embodiment of the invention provides a method for charging a battery, which comprises a mobile terminal such as a smart phone, a tablet computer, a wearable device (a smart watch, a smart glasses), a vehicle terminal, etc., the mobile terminal has a rechargeable battery, and the rechargeable battery is a mobile terminal. Power supply; rechargeable batteries can be in various forms, such as nickel-cadmium batteries, nickel-hydrogen batteries, lithium-ion batteries, and lithium-ion polymer batteries.

As shown in Figure 1, the method includes:

S101: detecting a current temperature of the rechargeable battery;

For example, when the user needs to charge the mobile terminal, the charging power source is first connected to the rechargeable battery. At this time, the mobile terminal detects the current temperature of the rechargeable battery through a device such as a temperature sensor provided on the mobile terminal.

Preferably, in order to meet the needs of users in different application scenarios, the mobile terminal can also set the charging mode to two types, namely, a normal charging mode and a smart charging mode, and the user can manually select before charging. When the user selects the normal charging mode, the mobile terminal controls the charging battery to charge with the rated current as the charging input current; when the user selects the smart charging, the mobile terminal controls to execute S101.

In a specific implementation process, the mobile terminal can periodically detect the current temperature of the rechargeable battery, for example, detecting every 5 minutes, or detecting the current temperature of the rechargeable battery in real time. Of course, there may be other The detection method is not specifically limited in the present invention.

In another embodiment, in order to facilitate the user to observe the charging condition of the rechargeable battery, the charging mode of the rechargeable battery, the current temperature of the rechargeable battery, the charging progress, and the like may also be displayed on the display screen of the mobile terminal.

S102: When the current temperature of the rechargeable battery meets a predetermined condition, the charging input current of the rechargeable battery is controlled to be reduced from the first current value to the second current value, so that the rechargeable battery is performed by the second current value. Charging.

For example, during the charging process, the mobile terminal determines whether the preset condition for adjusting the charging input current value is satisfied. When detecting that the current temperature of the rechargeable battery meets the preset condition, the mobile terminal decreases the charging input current value of the rechargeable battery, and no longer uses the larger first current value to charge the rechargeable battery, but uses the reduced second. The current value is charged by the rechargeable battery, so that the heat generated by the rechargeable battery decreases as the input current value decreases, preventing the temperature of the rechargeable battery from further increasing, thus effectively controlling the temperature of the rechargeable battery and prolonging the use of the rechargeable battery. Life expectancy reduces the probability of a high temperature explosion of a rechargeable battery.

In a specific implementation process, S102 may include: at least when detecting that the current temperature of the rechargeable battery is greater than a temperature threshold, the mobile terminal controls the charging input current of the rechargeable battery to decrease from the first current value to the second current value, so that the rechargeable battery The second current value is charged.

Here, the mobile terminal may, and is not limited to, the following three cases to determine whether the current temperature of the rechargeable battery satisfies a preset condition.

In the first case, the current temperature value of the rechargeable battery is compared with a preset temperature threshold. When the current temperature of the rechargeable battery is greater than the temperature threshold, determining that the current temperature of the rechargeable battery meets the preset condition, then the mobile terminal controls the rechargeable battery. The charging input current is reduced from the first current value to the second current value, such that the rechargeable battery is charged with the second current value. Due to rechargeable battery The reduction of the charging input current value reduces the heat generated by the rechargeable battery itself, preventing the temperature of the rechargeable battery from further increasing, thus effectively controlling the temperature of the rechargeable battery, prolonging the service life of the rechargeable battery, and reducing the charging. The probability of a high temperature explosion of the battery.

For example, the preset temperature threshold is 35 ° C and the mobile terminal is charging at a first current value, such as 1A. First, the mobile terminal detects the current temperature of the rechargeable battery, such as 40 ° C. Then, the mobile terminal compares the current temperature of the rechargeable battery with a temperature threshold. Here, the current temperature of the rechargeable battery is 40 ° C greater than the temperature threshold of 35 ° C. At this time, the mobile The terminal controls the input current value of the rechargeable battery to decrease from the first current value 1A to the second current value, such as 0.5A, and the rechargeable battery continues to charge at the second current value of 0.5A.

In another embodiment, the mobile terminal compares the current temperature with the temperature threshold after obtaining the current temperature of the rechargeable battery through S101. Then, the current temperature may not be greater than, that is, less than or equal to the temperature threshold. At this time, the mobile terminal may The input current value of the rechargeable battery is maintained at the first current value, so that the rechargeable battery remains charged with the first current value; the mobile terminal can also adjust the input current value of the rechargeable battery to the rated current value, so that the rechargeable battery maintains the rated current The value is charged. In practical applications, the rated current value is the rated output current value of the power adapter of each mobile terminal, such as 1A, 2A, 2.4A, and the like.

For example, the preset temperature threshold is 35 ° C and the mobile terminal is charging at a first current value, such as 1A. First, the mobile terminal detects the current temperature of the rechargeable battery, such as 30 ° C. Then, the mobile terminal compares the current temperature of the rechargeable battery with a temperature threshold. Here, the current temperature of the rechargeable battery is 30 ° C less than the temperature threshold of 35 ° C. At this time, the mobile The input current value of the terminal control rechargeable battery is maintained at the first current value 1A, and the rechargeable battery continues to be charged at the first current value 1A.

In the second case, in order to avoid frequent changes in the input current value of charging, which affects the stability of the rechargeable battery, the mobile terminal can also compare the current temperature of the rechargeable battery with the last detection while comparing the current temperature and temperature thresholds. The temperature difference is obtained, the current temperature increment of the rechargeable battery is obtained, and then the current temperature increment is compared with a preset change threshold. If When the current temperature of the rechargeable battery is greater than the temperature threshold, and the current temperature increment is greater than the change threshold, the mobile terminal controls the charging input current of the rechargeable battery to decrease from the first current value to the second current value, and the rechargeable battery performs the second current value. Charging. In this way, due to the decrease of the charging input current value of the rechargeable battery, the heat generated by the rechargeable battery itself is reduced, and the temperature of the rechargeable battery is further prevented from rising. Thus, the temperature of the rechargeable battery is effectively controlled, and the use of the rechargeable battery is prolonged. Life expectancy reduces the probability of a high temperature explosion of a rechargeable battery.

For example, the preset temperature threshold is 35 ° C, the preset change threshold is 2 ° C, and the mobile terminal is charging at a first current value, such as 1 A. First, the mobile terminal detects the current temperature of the rechargeable battery, such as 40 ° C, and obtains the temperature of the previously detected rechargeable battery, such as 37 ° C, then the mobile terminal compares the current temperature of the rechargeable battery with the temperature threshold, and will present The temperature increment is compared with the change threshold. Here, the current temperature of the rechargeable battery is 40 ° C is greater than the temperature threshold of 35 ° C, and the current temperature increment of 3 ° C is greater than the change threshold of 2 ° C. At this time, the mobile terminal controls the input current value of the rechargeable battery by The first current value 1A is reduced to a second current value, such as 0.5A, and the rechargeable battery continues to be charged at a second current value of 0.5A.

In another embodiment, after obtaining the current temperature and the current temperature increment of the rechargeable battery through S101, the mobile terminal compares the current temperature with the temperature threshold, and compares the current temperature increment with the change threshold, then, when When the temperature is greater than the stability threshold, the current temperature increment may not be greater than, that is, less than or equal to the change threshold. At this time, the mobile terminal may maintain the input current value of the rechargeable battery as the first current value, so that the rechargeable battery maintains the first current value. Charging is performed; the mobile terminal can also adjust the input current value of the rechargeable battery to a rated current value, so that the rechargeable battery remains charged at the rated current value.

For example, the preset temperature threshold is 35 ° C, the preset change threshold is 2 ° C, and the mobile terminal is charging at a first current value, such as 1 A. First, the mobile terminal detects the current temperature of the rechargeable battery, such as 37 ° C, and obtains the temperature of the previously detected rechargeable battery, such as 36 ° C. Then, the mobile terminal compares the current temperature of the rechargeable battery with the temperature threshold, and will present Temperature increment and The change threshold is compared. Here, the current temperature of the rechargeable battery is 37 ° C is greater than the temperature threshold of 35 ° C, but the current temperature increment of 1 ° C is less than the change threshold of 2 ° C. At this time, the mobile terminal controls the input current value of the rechargeable battery to remain the first current. At a value of 1 A, the rechargeable battery continues to be charged at the first current value of 1A.

In the third case, in order to avoid frequent changes in the input current value of charging, which affects the stability of the rechargeable battery, the mobile terminal can also compare the current temperature and temperature thresholds, and the mobile terminal can also detect the rechargeable battery according to the previous several times. The temperature determines the trend of the current temperature of the rechargeable battery. If the current temperature of the rechargeable battery is greater than the temperature threshold and the current temperature is increasing, the input current value of the mobile terminal controlling the rechargeable battery is decreased from the first current value to the second current value, and the rechargeable battery is charged at the second current value. In this way, due to the decrease of the charging input current value of the rechargeable battery, the heat generated by the rechargeable battery itself is reduced, and the temperature of the rechargeable battery is further prevented from rising. Thus, the temperature of the rechargeable battery is effectively controlled, and the use of the rechargeable battery is prolonged. Life expectancy reduces the probability of a high temperature explosion of a rechargeable battery.

For example, the preset temperature threshold is 35 ° C and the mobile terminal is charging at a first current value, such as 1A. First, the mobile terminal detects the current temperature of the rechargeable battery, such as 40 ° C, and obtains the temperature of the recently detected rechargeable battery, such as obtaining the last 10 detected rechargeable battery temperatures: 37 ° C, 37 ° C, 38 ° C, 38 °C, 38 ° C, 39 ° C, 39 ° C, 40 ° C, 40 ° C, 40 ° C, then, the mobile terminal compares the current temperature of the rechargeable battery with the temperature threshold, and determines the trend of the previous temperature, here, the current state of the rechargeable battery The temperature 40 ° C is greater than the temperature threshold of 35 ° C. Since the temperature values of the rechargeable batteries measured in the last 10 times increase sequentially, it can be said that the temperature of the rechargeable battery continues to rise in the recent period of time, that is, the development trend of the temperature of the rechargeable battery is continued. Raised, at this time, the mobile terminal controls the input current value of the rechargeable battery to decrease from the first current value 1A to the second current value, such as 0.5A, and the rechargeable battery continues to be charged at the second current value of 0.5A.

In another embodiment, after obtaining the current temperature of the rechargeable battery and the most recently measured charged battery temperature through S101, the mobile terminal compares the current temperature with the temperature threshold, and determines the current temperature trend, then, when Current temperature when the current temperature is greater than the stability threshold The trend can also be left unchanged or declining. At this time, the mobile terminal can maintain the input current value of the rechargeable battery as the first current value, so that the rechargeable battery remains charged with the first current value; the mobile terminal can also adjust the input current value of the rechargeable battery to the rated current value, so that The rechargeable battery remains charged at the rated current value.

For example, the preset temperature threshold is 35 ° C and the mobile terminal is charging at a first current value, such as 1A. First, the mobile terminal detects the current temperature of the rechargeable battery, such as 40 ° C, and obtains the temperature of the last 10 times of real-time detection of the rechargeable battery, respectively: 37 ° C, 37 ° C, 38 ° C, 38 ° C, 38 ° C, 39 ° C, 39 ° C, 38 ° C, 38 ° C, 38 ° C, then, the mobile terminal compares the current temperature of the rechargeable battery with the temperature threshold, and determines the current temperature trend, where the current temperature of the rechargeable battery is 40 ° C is greater than the temperature threshold of 35 ° C However, it can be seen from the temperature of the rechargeable battery measured in the last 10 times that the temperature of the rechargeable battery begins to decrease after rising, indicating that the current temperature of the rechargeable battery has a decreasing trend. At this time, the mobile terminal controls the input current of the rechargeable battery. The value remains at the first current value of 1 A, and the rechargeable battery continues to be charged at the first current value of 1 A.

Certainly, the foregoing preset conditions are other conditions, and the current temperature of the rechargeable battery may be determined by other methods to meet the preset condition, which is not specifically limited by the present invention.

It should be noted that, in one or more of the above embodiments, the second current value can be obtained by the following formula (1).

Where I is the second current value, t is the current temperature of the rechargeable battery, T ₁ is the preset temperature threshold, T ₂ is the highest temperature of the rechargeable battery in the battery industry standard, and i is the maximum value of the input current of the rechargeable battery.

According to formula (1), when the current temperature t of the rechargeable battery is lower than or equal to the temperature threshold T ₁ , the maximum current value i is the input current value of the rechargeable battery, when the current temperature t of the rechargeable battery is greater than the temperature threshold T ₁ , and When the current temperature increment is greater than the incremental threshold Δt, the second current value I calculated by equation (1) is the input current value of the rechargeable battery.

In addition, the corresponding relationship between the temperature of the rechargeable battery and the input current value may be pre-set in the mobile terminal, and the temperature of the rechargeable battery may be divided into a plurality of step temperature segments from low to high, and each temperature segment corresponds to a different input. a current value, when the current temperature of the rechargeable battery is within one of the temperature ranges, the mobile terminal charges the rechargeable battery as the second current value corresponding to the input current value of the temperature range, wherein the higher the temperature of the rechargeable battery is, the corresponding The smaller the input current value.

Of course, the second current value can also be obtained by other means, which is not specifically limited in the present invention.

The above method will be described by a specific example:

Assumed that the mobile terminal is at a first current value, such as charging 2A, the preset temperature threshold value T ₁ = 35 ℃, increment threshold ΔT = 2 ℃.

First, when the detection period arrives, the mobile terminal detects the current temperature t of the rechargeable battery, such as t=40 ° C;

Then, the mobile terminal compares the current temperature t=40° C of the rechargeable battery with the temperature threshold T ₁ =35° C., at the same time, calculates the current temperature increment of the rechargeable battery, that is, the current temperature and the temperature of the previously detected rechargeable battery t =35 °C for the difference, at this time, the current temperature increment Δt = 5 ° C, then, the current temperature increment Δt = 5 ° C compared with the change threshold ΔT = 2 ° C, at this time, the current temperature of the rechargeable battery t = 40 °C is greater than the temperature threshold T ₁ =35 ° C, and the current temperature increment Δt=5 ° C is greater than the change threshold ΔT=2 ° C, that is, the current temperature of the rechargeable battery satisfies the preset condition.

At the same time, according to the battery industry standard, the maximum value of the input current of the rechargeable battery is i=2A, and the maximum temperature of the rechargeable battery is T ₂ =60°C. The above parameter value is substituted into the formula (1) to calculate the second current value I. = 1.6A, then, the mobile terminal controls the input current value of the rechargeable battery to decrease from the first current value 2A to the second current value of 1.6A, and charges the rechargeable battery at 1.6A.

Thus, the process of adjusting the input current value of the rechargeable battery according to the temperature of the rechargeable battery is completed.

It can be seen from the above that, according to the technical solution provided by the embodiment of the present invention, when the temperature of the rechargeable battery meets the preset condition during the charging process, the charging can be adjusted by reducing the charging input current value. The temperature of the electric battery causes the heat generated by the rechargeable battery to decrease as the input current value decreases, preventing the temperature of the rechargeable battery from further increasing, thus effectively controlling the temperature of the rechargeable battery and prolonging the service life of the rechargeable battery. Reduces the probability of a high temperature explosion of a rechargeable battery.
