Detailed ways

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

Fig. 2 is a schematic flowchart of a charging control method according to an exemplary embodiment. As shown in Fig. 2, the method is used in a terminal and includes the following steps.

Step S11, detecting the battery voltage in real time.

In one embodiment, real-time detection may refer to periodic detection with a shorter period (for example, a period of 2 seconds), or it may refer to aperiodic detection with a shorter time interval, such as two adjacent The time interval between detections may be 1 second, or 2 seconds, or 3 seconds.

Step S12, determining the charging current in real time according to the rated charging power of the battery and the battery voltage detected in real time.

Fig. 3 is a schematic diagram showing changes in battery voltage and current according to an exemplary embodiment.

In one embodiment, the battery voltage increases gradually during the charging process. For example, it may rise proportionally from V ₁ ′ to V ₁ as shown in FIG. 3 , or it may rise in other ways, such as parabolically.

In one embodiment, since the battery voltage gradually rises during the charging process, but the rated charging power of the battery remains unchanged during the charging process, the charging current can be used as the quotient of the rated charging power and the battery voltage. During the rising process of the battery voltage, the charging current determined in real time may decrease gradually, for example, from I ₁ to I ₁ ′ as shown in FIG.

Step S13, charging the battery with the charging current determined in real time.

Since the charging current in the related art remains constant until the battery voltage reaches V ₀ ', that is, before t ₀ , the charging power is always less than the rated charging power P ₀ of the battery, until the battery voltage is equal to V ₀ ', the charging power is It is equal to the rated charging power P ₀ of the battery, that is, I ₀ ×V ₀ ′=P ₀ .

In one embodiment, the initial battery voltage V ₁ in this embodiment is the same as the initial battery voltage V ₀ in the related art, V ₁ ′ is the same as V ₀ ′, and the rated charging power P ₁ is also the same as in the related art In the case of the same rated charging power P ₀ , since I ₀ =P ₀ /V ₀ ', I ₁ =P ₁ /V ₁ , where V ₁ =V ₀ <V ₀ ', it can be obtained that P ₀ / V ₀ ′<P ₁ /V ₁ , that is, I ₁ >I ₀ . Therefore, compared with the charging scheme in the related art, this embodiment can charge the battery with a relatively large initial charging current I ₁ , and gradually reduce the charging current during the rising process of the battery voltage until the battery voltage rises to V ₁ ′, Therefore, the battery voltage reaches V ₁ ′ as soon as possible, that is, t ₁ <t ₀ , which shortens the constant current charging phase in the related art, thereby shortening the charging time.

Fig. 4 is a schematic flowchart of another charging control method according to an exemplary embodiment. As shown in Fig. 4, the above method further includes:

Step S14, reducing the charging current when it is detected that the battery voltage rises to a first preset voltage value.

In one embodiment, according to different batteries, the first preset voltage value can also be different, the first preset voltage value can be the voltage value when the battery is fully charged, or a voltage slightly lower than the voltage value when the battery is fully charged For example, for a common battery, the first preset voltage value may be 4.2V. When the battery is at or close to full capacity, a large current may easily cause the battery to overcharge and may damage the battery. Therefore, in this case, the charging current can be gradually reduced to ensure that the battery is fully charged. damage the battery.

Fig. 5 is a schematic flowchart of another charging control method according to an exemplary embodiment. As shown in Fig. 5, the above method further includes:

Step S15, determine whether the charging control command input by the user is received, if received, execute step S11, if not received, execute step S16;

Step S16, charging the battery with a constant current.

In one embodiment, the user can choose to charge the battery by using the charging method in this embodiment, or by using the charging method in the related art, charging the battery with a constant current according to needs. For example, when the rated charging current of the battery is large, the charging method in this embodiment can be used to charge the battery by inputting a charging control command; while when the rated charging current of the battery is small, the relevant The charging method in the technology charges the battery.

Fig. 6 is a schematic flowchart of another charging control method according to an exemplary embodiment. As shown in Fig. 6, the above method further includes:

Step S17, calculating the first time from charging the battery with the charging current determined in real time to the first time when the battery voltage rises to a first preset voltage value, and charging the battery with a constant current, the battery voltage a second time for rising to the first predetermined voltage value;

Step S18, generating prompt information according to the first time and the second time.

In one embodiment, the first preset voltage value can be V ₁ ′ shown in FIG. 3 , or V ₀ ′ shown in FIG. 1 , then the first time can be t shown in FIG. 3 ₁ , the second time can be t ₀ described in Figure 1, according to the embodiment shown in Figure 2, t ₁ <t ₀ , so it can be done by making a difference between t ₀ and t ₁ (other methods can also be selected as required) , such as t ₁ and t ₂ ), the obtained difference time is used as a prompt message, so that the user can intuitively and clearly understand how much charging time is saved by the charging method in this embodiment.

Fig. 7 is a schematic flowchart of another charging control method according to an exemplary embodiment. As shown in Fig. 7, the above method further includes:

Step S111, determine whether the detected battery voltage is less than the second preset voltage value, if less, execute step S19, if not, execute step S12, determine the charging current in real time according to the rated charging power of the battery and the real-time detected battery voltage .

Step S19, charging the battery by trickle current.

In one embodiment, when the battery voltage is low, for example, less than the second preset voltage value, a larger charging current will cause greater damage to the battery, so in this case, it can be charged with a smaller The electric current, also known as the trickle current, charges the battery to ensure that the battery is not damaged during the charging process. Wherein, for a battery whose battery voltage is 4.2V when fully charged, the second preset voltage value may be 2.9V, and the trickle current may be 1/10 of the charging current when entering the constant voltage stage.
