[0023] 基于图1所示的电池充电装置,本实用新型实施例还可提供一种电池充电方法,如图2所示,该电池充电方法包括以下步骤: [0023] Based on the battery charging apparatus shown in FIG. 1, the embodiment of the present invention may further provide a battery charging method shown in Figure 2, the battery charging method comprising the steps of:

[0024] S1.在对电池300进行充电的过程中,电源适配器100先按照常规充电模式对电池300进行充电; . [0024] S1 in the process of charging the battery 300, the power adapter 100 to charge the battery 300 in accordance with the normal charging mode;

[0025] S2.当电源适配器100的输出电流值在预设时间间隔内处于常规电流区间时,电源适配器100与充电控制模块200进行快充询问通信; . [0025] S2 when the output current value of the power adapter 100 is in the normal current range within a predetermined time interval, the power adapter 100 and the charging control module 200 for fast charge inquiry communication;

[0026] S3.在充电控制模块200向电源适配器100发出快充指示命令后,电源适配器100根据充电控制模块200所反馈的电池电压信息调整输出电压; . [0026] S3 the charge control module 200 issues a command indicating the fast charge, the output voltage of the power adapter 100 to adjust the battery charging voltage information control module 200 to the power supply adapter 100 feedback;

[0027] S4.在电源适配器100的输出电压符合充电控制模块200所预设的快充电压条件时,电源适配器100按照快速充电模式调整输出电流和输出电压以对电池300进行充电,且充电控制模块200同时从电源适配器100引入直流电对电池300进行充电。 [0027] S4. When the output voltage of the power adapter 100 is in line with the pre-charge control module 200 fast-charge voltage conditions, the power adapter 100 to adjust the output current and output voltage to charge the battery 300 in the quick charging mode and the charging control while module 200 charges the battery 300 from the power adapter 100 is introduced direct current.

[0028] 其中,预设时间间隔可取值为3S (秒),常规电流区间可设定为[1A,4A]。 [0028] wherein the predetermined time interval is desirable 3S (s), conventional current interval may be set to [1A, 4A].

[0029] 考虑到电源适配器100的输出电流值会存在不处于常规电流区间的情况,所以,基于图2所示的电池充电方法,如图3所示,步骤SI之后还包括以下步骤: [0029] Taking into account the output current of the power adapter 100 value is not in the presence of conventional current interval, therefore, the battery charging based on the method shown in FIG. 2, FIG. 3, after the step SI further comprising the step of:

[0031] S6.当电源适配器100的输出电流值小于电流下限值时,返回执行步骤S5 ; . [0031] S6 when the output current of the power adapter 100 is less than the value of the current lower limit value, returns to step S5;

[0032] S7.当电源适配器100的输出电流值大于电流上限值时,电源适配器100关闭直流电输出。 [0032] S7. When the current upper limit value of the output current is greater than the power adapter 100, the adapter 100 off the DC power output. 此时可判定为输出短路,所以电源适配器100关闭直流电输出以实现短路保护。 At this time may be determined that the output short-circuited, the DC output of the power adapter 100 is closed to short-circuit protection.

[0033] 其中,上述的步骤S6和步骤S7是与步骤S2并列的方法步骤,分别用于应对电源适配器100的输出电流值小于电流下限值和大于电流上限值的情况;上述的电流下限值和电流上限值可分别取值为IA和4A。 [0033] wherein the above-described steps S6 and S7 are juxtaposed method step and step S2, respectively, for coping with the case of the output current of the power adapter 100 is less than the upper limit value and larger than the current value of a current; the above-described current and the current upper limit value may be the upper limit value, respectively IA and 4A.

[0034] 在执行上述步骤S2之后,考虑到会存在充电控制模块200不向电源适配器100发出快充指示命令的情况(包括通信失败或充电控制模块200反馈快充否决命令),所以在图3所示的电池充电方法中,在步骤S2之后还包括以下步骤: [0034] After performing the above step S2, taking into account exist charging control module 200 is not the power adapter emits fast charge instruction command 100 (including a communication failure or the charge control module 200 and feedback fast charge rejected command), so that in FIG. 3 battery charging method shown in the step S2 after further comprising the step of:

[0035] S8.在充电控制模块200不向电源适配器100发出快充指示命令时,返回执行步骤S5。 [0035] S8. When the charge control module does not issue a command to indicate fast charging power adapter 100 200, execution returns to step S5.

[0036] 由此可知,步骤S8是与步骤S3并列的方法步骤,即在充电控制模块200未指示电源适配器100进入快速充电模式时,电源适配器100继续对输出电流进行检测判断。 [0036] It can be seen, step S8 and step S3 are juxtaposed method step, i.e., when the charge control module 200 instructs the power adapter 100 does not enter the fast charge mode, the power adapter 100 continues to detect the output current is determined.

[0037] 如图3所示,在步骤S3与步骤S4之间,电池充电方法还包括以下步骤: [0037] 3, between step S3 and step S4, the battery charging method further comprising the steps of:

[0038] S9.电源适配器100与充电控制模块200进行快充电压询问通信,并将输出电压信息反馈至充电控制模块200; . [0038] S9 power adapter 100 and the charging control module 200 for communication to ask fast-charge voltage and an output voltage feedback to the charging control module 200;

[0040] 其中,上述的快充电压条件可以是快充电压额定区间或快充电压额定值,S卩如果电源适配器100的输出电压处于快充电压额定区间或等于快充电压额定值,则证明电源适配器100的输出电压符合快充电压条件。 [0040] wherein the fast-charge voltage conditions can be fast or fast charging section charging voltage rated voltage rating, S Jie when the output voltage of the power adapter 100 is in the fast-charge voltage equal to the desired range, or fast-charge voltage rating, the proof the output voltage of the power adapter 100 is in line with the fast-charge voltage conditions. 如果在步骤SlO执行后,充电控制模块200未反馈任何信号至电源适配器100,则表明两者之间通信失败,电源适配器100需要执行复位操作。 If, after performing step SlO, the charging control module 200 does not return any signal to the power adapter 100 indicates a communication failure between the two, the power adapter 100 needs to perform a reset operation.

[0041] 另外,考虑到电源适配器100的输出电压存在不符合充电控制模块200所预设的快充电压条件的情况,如图3所示,步骤SlO与步骤S4之间还包括以下步骤: [0041] Further, in consideration of the output voltage of the power adapter 100 is present do not meet the pre-charge control module 200 in the case of fast-charge voltage conditions, as shown in FIG. 3, step SlO step further comprises the step of between S4:

[0042] Sll.在电源适配器100的输出电压不符合充电控制模块200所预设的快充电压条件时,充电控制模块200发送电压偏差反馈信号至电源适配器100 ; . [0042] Sll output voltage of the power adapter 100 does not meet a preset charge control module 200 fast-charge voltage conditions, the charging bias voltage control module 200 transmits a feedback signal 100 to the power adapter;

[0044] 需要说明的是,电压偏差反馈信号包括电压偏低反馈信号和电压偏高反馈信号,如果电压偏低,则电源适配器100根据电压偏低反馈信号将输出电压调高,如果电压偏高,则电源适配器100根据电压偏高反馈信号将输出电压调低。 [0044] Incidentally, the feedback signal comprises a bias voltage feedback signal voltage is low and the feedback signal voltage is high, if the voltage is low, the power adapter 100 to adjust output voltage signal, if the high voltage according to the feedback voltage is low , the high voltage power adapter 100 according to the output voltage feedback signal down.

[0045] 此外,如图3所示,在步骤S4之后还包括以下步骤:[0046] S13.充电控制模块200对电池300的电压进行检测,并判断电池300的电压是否大于快充阈值电压,是,则执行步骤S14,否,则返回执行步骤S4 ; [0045] Further, as shown in FIG. 3, after the step S4 further comprises the step of:. [0046] S13 Voltage 200 battery charging control module 300 is detected, and determines whether the voltage of the battery 300 is greater than the threshold voltage of the fast charge, yes, step S14, otherwise, the process returns to step S4;

[0047] S14.充电控制模块200停止从电源适配器100引入直流电对电池300进行充电,并反馈快充关闭指令至电源适配器100 ; . [0047] S14 charge control module 200 stops charging the battery 300 from the DC power supply adapter is introduced 100, and feedback fast charge-off command to the power adapter 100;
