Detailed Description
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, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 3 is a schematic flow chart diagram illustrating a battery charge control method that may be adapted to control charging of a lithium battery, according to an exemplary embodiment. As shown in fig. 1, the method includes the following steps.
In step S11, the battery is charged with a charging current greater than a rated current of the battery.
In one embodiment, the charging current I1May be the rated current I of the battery01.2 to 3 times, and can be specifically set according to the maximum current that the battery can bear. For exampleCharging current I1Is rated current I01.5 times of the rated current I0At 3600 mAmp-hr, charging current I1May be 5400 milliamps. Charging the battery with a charging current greater than the rated current allows the battery to reach the rated voltage in a shorter time than charging the battery with the rated current according to the related art, i.e., I in fig. 61Greater than I in FIG. 20In the case of (1), t in FIG. 51Less than t in FIG. 10。
In step S12, the charging current is decreased when the voltage of the battery is equal to a preset voltage.
Fig. 4 is a schematic diagram illustrating a connection relationship of a battery according to an exemplary embodiment. In one embodiment, as shown in fig. 4, a charge management chip (also referred to as a power management chip) is connected to a package (Pack) of the battery, and the charging current and the charging voltage can be controlled by the charge management chip.
The resistance of the battery cell is R3, the resistance of a line between the positive electrode of the battery and the positive electrode of the charge management chip is R1, and the resistance of a line between the negative electrode of the battery and the negative electrode of the charge management chip is R2, the voltage between the package positive electrode Pack + and the package negative electrode Pack-is generally used as the voltage of the battery, that is, the voltage of the battery is (R1+ R2+ R3) × charging current, and accordingly, when the charging current is determined, the voltage of the battery can be determined, and whether the voltage of the battery is equal to the preset voltage or not is determined.
In one embodiment, the voltage of the battery may be suddenly reduced by reducing the charging current, while the voltage of the battery may gradually rise back up until it again equals the nominal voltage, since the charging current is still present.
In step S13, it is determined whether the reduced charging current satisfies the preset current condition and/or the preset number of times condition, if not, step S14 is performed, and if so, step S15 is performed.
In one embodiment, it may be determined whether the number of times the charging current is reduced satisfies a preset number condition, and/or the current value of the reduced charging current to determine whether it satisfies the preset current condition. The step S14 may be executed when the reduced charging current satisfies one of the preset current condition and the preset frequency condition, or the step S14 may be executed when the reduced charging current satisfies both the preset current condition and the preset frequency condition. The specific determination mode can be set as required.
In step S14, the reduced charging current is used as the charging current, and the process returns to step S12, and when the voltage of the battery is equal to the preset voltage, the charging current is reduced continuously.
In one embodiment, in the case that the reduced charging current does not satisfy the preset condition, step S12 may be repeated, that is, when the voltage of the battery is equal to the preset voltage, the reduced charging current is further reduced, for example, as shown in fig. 6, the charging current is set to be I1Is reduced to I2If I is2If the preset condition is not satisfied, then I may be further set when the voltage of the battery is equal to the preset voltage2Is reduced to I3…, until the reduced charging current meets the preset condition.
In step S15, when the voltage of the battery is equal to a preset voltage, the battery is charged by a constant voltage signal having a voltage equal to the preset voltage.
In one embodiment, such as in FIG. 6, when the charging current is reduced to I3And then, the charging current meets the preset condition. Since the charging current is reduced at least once when the charging current satisfies a predetermined condition, e.g. I3Relative to I1Has undergone two reductions, thus I3Already small, when charging the battery by means of the constant voltage signal, the charging current can be reduced to 0, i.e. t, in a short time3To t4Shorter. And after the charging current is reduced each time, the voltage of the battery can quickly rise to the rated voltage, namely the time for the voltage of the battery to rise to the rated voltage is short, namely t1To t2And t3To t3Shorter.
Tested, where t1To t2、t2To t3And t3To t4The sum of the three time periods, i.e. the time period from the first reduction of the charging current to the reduction of the charging current to 0, is similar to the constant voltage charging period in the related art, i.e. the time period from the reduction of the charging current from the rated current to 0, i.e. t in fig. 20To t0' proximal. However, since the present embodiment charges the battery with a charging current larger than the rated current, t1Is significantly less than t0That is, it takes less time for the battery voltage to reach the rated voltage for the first time than the related art, so that the entire charging time period of 0 to t4Less than charging period 0 to t in the related art0Thereby reducing the charging time of the battery and improving the charging speed of the battery.
FIG. 7 is a schematic flow chart diagram illustrating another battery charge control method in accordance with an exemplary embodiment. As shown in fig. 7, on the basis of the embodiment shown in fig. 3, the determining whether the reduced charging current satisfies the preset current condition and/or the preset number of times condition includes:
in step S131, it is determined whether the reduced charging current is smaller than the rated current, and if so, it is determined that the reduced charging current satisfies the preset current condition.
In one embodiment, it may be determined that the reduced charging current satisfies the preset current condition in a case where the charging current is less than the rated current. For example, in FIG. 6I3Is less than I in FIG. 20Then, step S15 may be performed. Accordingly, when I3Is less than I0Then, in the stage of charging by the constant voltage signal, the charging current is from I3Time period t reduced to 03To t4Specific charging current from I0Time period t reduced to 00To t0Is short, and t1To t2And t2To t3The two time periods are very short, so t can be ensured to a great extent2To t4Less than t0To t0', further at t1Is significantly less than t0On the basis of (1), the charging time is ensured to be 0 to t4Can be effectively reduced.
Fig. 8 is a schematic flow chart diagram illustrating yet another battery charge control method in accordance with an exemplary embodiment. As shown in fig. 8, on the basis of the embodiment shown in fig. 3, the determining whether the reduced charging current satisfies the preset condition includes:
in step S132, it is determined whether the reduced charging current is reduced more than a preset number of times, and if so, it is determined that the reduced charging current satisfies a preset current condition and/or a preset number of times condition.
In one embodiment, it may be determined that the reduced charging current satisfies the preset number condition in a case where the number of times the charging current is reduced is greater than the preset number. Therefore, on the premise of ensuring that the charging time is shortened, the charging current is prevented from being reduced by the charging management chip for too many times, and as the charging current is reduced each time, the battery voltage needs to wait for the battery voltage to rise to the rated voltage, the charging current is reduced too much, and the charging time is prolonged to a certain extent, so that according to the embodiment, on one hand, the power consumption of the charging management chip can be reduced, and on the other hand, the charging time can be ensured to be shortened.
It should be noted that the embodiment shown in fig. 8 can be applied to the embodiment shown in fig. 7.
Fig. 9 is a schematic flow chart diagram illustrating yet another battery charge control method in accordance with an exemplary embodiment. As shown in fig. 9, based on the embodiment shown in fig. 3, the reducing the charging current includes:
in step S121, 1/n of the initial charging current is subtracted from the charging current, where n is an integer greater than 1.
In one embodiment, by decreasing the charging current in the manner of step S121, it can be ensured that the charging current decreases regularly, for example, in the case where n is 3, 1/3 of the initial current can be subtracted from the current each time the current is decreased, for example, I in fig. 62＝I1*2/3，I3＝I11/3 to simplify the processing logic of the charge management chip for reduced current operation.
Alternatively, n ≧ 3.
In one embodiment, on the basis of the embodiment shown in fig. 9, since each current reduction is performed by the same value, which is related to the initial current on the one hand and n on the other hand, the initial current needs to be set larger to reduce the charging time, and if n is set smaller, the value of each current change is too large, which may cause damage to the battery. According to the embodiment, the minimum value of n is set to 3, 1/3 which can reduce the initial current at most each time can be ensured, thereby alleviating the damage of the charging current change to the battery.
In one embodiment, the larger the current, the larger the value of n, thereby further avoiding damage to the battery from variations in charging current.
Corresponding to the embodiment of the battery charging control method, the disclosure also provides an embodiment of a battery charging control device.
