Technical field

The embodiments of the present invention relate to the field of communications technologies, and in particular, to a battery charging control method and terminal.

Background technique

With the development of technology, people are becoming more and more dependent on mobile devices, such as mobile phones and tablets. With the high-intensity use of mobile devices, the number of times the mobile device is charged is increased. In the battery product design, a fixed charging current and a cut-off voltage are set according to the initial capacity C of the battery, and the charging current is used in subsequent use. And the cutoff voltage does not change. Among them, the maximum allowable charging current ensures that the entire charging process is safe; the charging cut-off voltage cannot be higher than the maximum voltage of the battery, ensuring that the battery will not be over-flushed to cause the drum.

However, as battery life increases, battery capacity continues to decay. If the charging current is not reduced, the actual charging rate of the battery will increase.

When the current capacity value Y of the battery decreases, the difference between the initial capacity value W of the battery and the current capacity value Y of the battery increases, thereby causing the capacity change state value S to increase.

detailed description

The technical solution of the present invention will be further described in detail below through the accompanying drawings and embodiments.

The charging control method of the battery provided by the present application is applied to the structural frame diagram shown in FIG. 1. A mobile terminal and a charger terminal may be included in FIG. 1, the mobile terminal may include a rechargeable battery, and the terminal controls charging parameters of the battery when the battery is charged. In the embodiment of the present invention, the terminal may be referred to as a user equipment (User Equipment, referred to as "UE"), a mobile station (Mobile Station, referred to as "MS"), a mobile terminal (Mobile Terminal), a computer, a microcomputer, etc. . The terminal can communicate with one or more core networks via a Radio Access Network (RAN), for example, the terminal can be a mobile phone (or "cellular" phone), a mobile computer, and Mobile terminal computers, smart watches, etc., for example, the terminals may also be portable, pocket-sized, handheld, computer-integrated or in-vehicle mobile devices that exchange voice and/or data with the wireless access network. The invention is not limited thereto, for example, the terminal further includes a terminal with wired access with multiple bearer features.

The charging process of the terminal battery can be divided into three stages: a trickle charging phase, a constant current charging phase, and a constant voltage charging phase. The trickle charge phase is a precharge phase. When the initial/no-load voltage of the battery is lower than the pre-charge threshold or the battery power is lower than the preset threshold, the trickle charging phase is passed. For example, the pre-charge threshold of a single lithium-ion battery is generally 3.0V or the battery power is lower than the total. At 8% of the charge, the battery is charged with a smaller current. At this stage, the precharge current is about 10% of the current in the constant current charge phase. The constant current charging phase is a constant current charging phase. In order to save charging time, this phase generally uses the maximum charging current that the battery can withstand charging. As the charging progresses, the battery voltage gradually increases. The charging current value in the constant voltage charging phase is gradually decreased, and when the battery voltage reaches the charging cutoff voltage, it is judged that the battery is fully charged.

After the terminal is used for a long time, the battery capacity it carries will decrease. In this case, the present invention provides a method of charging control of the battery.

FIG. 2 is a flowchart of a method for charging control of a battery according to an embodiment of the present invention. The executor of the method may be a terminal. As shown in FIG. 2, the method may specifically include:

Step 210: Obtain an initial capacity value of the battery.

Ways to obtain the initial capacity value of the battery include, but are not limited to, the following:

Method 1: During the process from the battery power emptying to the battery power filling, the total current flowing into/out of the battery is continuously integrated by the fuel gauge, and the net charge amount obtained by the integration is summed to obtain the initial capacity value of the battery.

Method 2: Obtain the initial capacity value of the battery by the nominal rated capacity of the battery preset by the mobile phone.

Mode 3: In the case of a constant current, that is, in an ideal state, during the period from the empty battery to the full charge, the initial capacity value of the battery is obtained by the current flowing into the battery and the time required for the battery to be fully charged. Specifically, the capacity of the battery is usually expressed in ampere-hours or milliamperes per hour (abbreviated as A·H or mA·H). After the battery power is emptied, the battery is charged, and by charging the battery, the charging current and the charging time are obtained, and the product value of the two is used as the initial capacity value of the battery.

In an example, after the battery is discharged, the battery is charged. When the battery is fully charged, the charging current is 1000 mA and the charging time is 3H. The product of the two is 3000 mAH, that is, the initial capacity of the battery is 3000 mAH. .

Step 220: Obtain a current capacity value of the battery.

After the terminal is used for a period of time, the period of time may be any time such as one week, one month or one year, and the terminal detects the capacity of the battery to obtain the current capacity value of the battery. The manner of obtaining the current capacity value of the battery includes, but is not limited to, the following methods:

Method 1: During the process from the battery power emptying to the battery power filling, the total current flowing into/out of the battery is continuously integrated by the fuel gauge, and the net charge amount obtained by the integration is summed to obtain the current capacity value of the battery. .

Method 2: In the case of a constant current, that is, in an ideal state, during the process from the empty battery to the full charge, the battery is obtained by the current flowing into the battery and the time required for the battery to be fully charged. The current capacity value is specifically: after the terminal is used for a period of time, before the terminal detects the capacity of the battery, the battery needs to be charged after the battery is emptied, and the battery is charged to obtain the charging used at this time. Current and charging time, the product value of the two is taken as the current capacity value of the battery. Wherein, the current capacity value of the battery is less than the initial capacity value of the battery.

In one example, the initial battery capacity of the terminal is 3000 mAH, and the battery capacity value decreases after the terminal is used for a long time. Because the battery capacity value decreases, for safety reasons, at this time, according to the usage time of the battery, etc., the 100 mA pre-pass is adopted. A small current (safe current) is used to charge the battery. When the battery is fully charged, the charging time is 20H, and thus the current capacity value of the battery is 2000mAH. The current capacity value of the battery is 2000 mAH less than the initial capacity value of the battery of 3000 mAH.

It can be understood that the terminal can detect the capacity of the battery in real time, or the terminal can periodically detect the capacity of the battery in one time period of one week, one month or one year, and at the same time, obtain the current capacity value of the battery. The method does not constitute a limitation on the method of obtaining the current capacity value of the battery, and there may be other ways to obtain the current capacity value of the battery as the technology develops.

Step 230: Determine a charging parameter of the battery according to an initial capacity value of the battery and a current capacity value of the battery.

The charging parameters may include a charging current value flowing into the battery and a charging cutoff voltage value of the battery. The charging current value may be a charging current value in a constant current charging phase, which represents a maximum charging current flowing into the battery at the current battery capacity; the charging cutoff voltage value is a battery voltage value that determines that the battery is full.

Optionally, the charge cutoff voltage value may also be a battery voltage value at which the battery is fully charged during the constant voltage charging phase.

Optionally, before determining the charging parameter of the battery, the method further includes:

The terminal acquires a capacity change state value of the battery according to the obtained initial battery capacity value and the acquired current capacity value of the battery.

Specifically, the capacity change state value of the battery, that is, the percentage of the current capacity of the battery relative to the initial capacity change, can satisfy the formula:

S=(W-Y)/W×100% (Formula 1)

S is the capacity change state value of the battery, W is the initial capacity value of the battery, and Y is the current capacity value.

The initial capacity value W of the battery is a fixed value; as the battery life time increases, the current capacity value Y of the battery continuously decreases. According to formula (1), when the current capacity value Y of the battery decreases, the initial capacity of the battery The difference between the value W and the current capacity value Y of the battery increases, resulting in an increase in the capacity change state value S.

Returning to step 203, the terminal determines the charging current value flowing into the battery and the charging cutoff voltage value of the battery according to the battery capacity change state value associated with the initial capacity value of the battery and the current capacity value of the battery.

Since the capacity value of the battery will decrease after the terminal is used for a long time, the percentage of the current capacity of the battery relative to the initial capacity change of the battery will increase, and the charging current value flowing into the battery and the charging cutoff voltage value of the battery need to be adjusted accordingly. To extend the life of the battery. It can be understood that adjusting the charging current value flowing into the battery refers to adjusting the current value flowing into the battery in the constant current phase, and adjusting the charging cutoff voltage value of the battery refers to adjusting the battery voltage value that determines the battery is full. The correspondence between the capacity change state value of the battery and the charging current value of the inflow battery and the charge cutoff voltage value of the battery is as shown in Table 1:

Table 1

容量变化状态值SCapacity change status value S	充电截止电压UCharging cutoff voltage U	充电电流ICharging current I
10％-20％10%-20%	U×(1-10％)U×(1-10%)	I×(1-10％)I × (1-10%)
20％-30％20%-30%	U×(1-20％)U×(1-20%)	I×(1-20％)I × (1-20%)
30％-40％30%-40%	U×(1-30％)U×(1-30%)	I×(1-30％)I × (1-30%)

In Table 1, the preset range of the capacity change state value S is 10%-20%, indicating that the battery current capacity value is reduced by more than 10% and less than 20% compared to the initial capacity value, and so on. The charge cut-off voltage U can be a nominal voltage of the battery, and the charge current I is a charge current corresponding to the charge cut-off voltage U and flowing into the battery by the charger.

When the preset range of the capacity change state value S of the battery is 10%-20%, the terminal reduces the charge cutoff voltage value U of the battery and the charging current value I of the inflow battery by 10%, that is, the current battery charge. The current value becomes I×(1-10%), and the value of the charge cut-off voltage that determines the battery is full becomes U×(1-10%); the preset range of the state change value S of the battery is 20%-30%. At this time, the terminal reduces the charge cutoff voltage value U and the charge current value I of the battery by 20%, that is, the charge current value flowing into the current battery becomes I×(1-20%), and determines the charge cutoff voltage value of the battery full. It becomes U×(1-20%); when the preset range of the capacity change state value S of the battery is 30%-40%, the terminal will charge the battery cut-off voltage value U and the charging current value I flowing into the battery. Decrease by 30% respectively, that is, the charging current value flowing into the current battery becomes I×(1-30%), and the value of the charging cut-off voltage that determines the battery is full becomes U×(1-30%), and other preset ranges and so on. .

The terminal determines the charging current value of the inflow battery and the charging cutoff voltage value of the battery corresponding to the acquired capacity change state value according to the capacity change state value S of the battery, by referring to the corresponding relationship described in Table 1. It can be seen that the capacity change state value S of the battery changes in proportion to the charging current flowing into the battery and the charging cutoff voltage of the battery, and the larger the capacity change state value of the battery, the smaller the charging current value flowing into the battery, and the charging cutoff voltage of the battery is also The lower.

It can be understood that the correspondence relationship between the capacity change state value of the battery shown in Table 1 and the charging current value of the inflow battery and the charge cutoff voltage value of the battery is only a feasible example, and according to the actual needs of the design, Table 1 can be The data information inside is changed.

It can be seen that as the battery life is prolonged, the current capacity value of the battery decreases, resulting in an increase in the battery capacity change state value. At this time, it is necessary to correspondingly reduce the charging current value flowing into the battery and the charging cutoff voltage value of the battery. . The terminal improves the safety of the battery by reducing the charging current flowing into the battery and the charging cutoff voltage of the battery, thereby prolonging the battery life.

Further, after step 230, the method may further include: charging the battery according to a charging parameter of the battery, such as a charging current value flowing into the battery and a charging cutoff voltage value of the battery, to avoid a non-safe event such as a bulging phenomenon of the battery. occur.

Alternatively, after step 230, the method may further include: according to a charging parameter of the battery, such as The charging current value flowing into the battery and the charging cutoff voltage value of the battery send an instruction to the charger for instructing the charger end to adjust the output charging current value.

It can be understood that the above two charging methods do not constitute a limitation on the charging method of the present invention, and may also be other charging methods.

The charging control method for the battery provided by the present invention first obtains the initial capacity value of the battery, and after the battery is used for a period of time, the current capacity value of the battery is obtained by detecting the capacity of the battery, and then according to the initial capacity value and the current The capacity value determines the charging parameters of the battery, thereby preventing non-safe events such as bulging after the battery is used for a long time, thereby ensuring the safety of the battery throughout the life cycle, thereby prolonging the service life of the battery.
