具体实施方式
为使本申请的上述目的、特征和优点能够更加明显易懂，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
本申请实施例所述的快速充电方法是在高性能充电器的基础上，通过提高充电电压的技术手段实现快速充电的目的。
恒压充电：以恒定的电压对电池进行充电。
电池耐受电压：电池充电时使用的最高的恒压充电电压。
电量满的门限电流：最高的恒压充电时，进电池的电流逐渐减少，减少到一个阈值时可以认为电池已充满，对用户显示电量达到100％，虽然显示电量100％，并不是充电截止。
充电截止电流：最高的恒压充电时，进电池的电流逐渐减少，减少到另一个阈值时可以认为电池已完全充满，此时应断开充电电路。即，充电截止电流是到了电量满的门限电流之后继续充电直至终止充电前的电流。
实施例1
图1为根据本申请实施例的快速充电方法流程图，下面将参考图1，对本申请实施例的快速充电方法进行详细描述。
本申请实施例中，可提供快速和普通充电两种充电模式。
首先，步骤101，检测充电器输出能力参数。
本实施例中，为对充电器的充电能力进行检测。即，***充电器时，对充电器进行充电器类型的识别，再根据不同的充电器类型，对充电器进行输出能力参数检测，确定充电器的输出功率、输出电压、输出电流等参数范围。
本申请实施例中，充电器类型可分为高性能充电器和普通充电器，高性能充电器即为支持快速充电的充电器，高性能充电器的基本标准是要满足快速充电的性能要求，具体的，本实施例采用的判断标准是当充电器的输出能力参数满足预设参数条件时，确定电池采用快速充电模式；当充电器的输出能力参数不满足预设参数条件时，确定电池采用普通充电模式。
上述预设参数条件为，充电器的输出功率不小于18W，且输出电压不小于9V/输出电流不小于2A时，采用快速充电模式；充电器的输出功率小于18W，且输出电压小于9V/ 输出电流小于2A时，采用普通充电模式。
在步骤102，根据输出能力参数判断充电器是否为高性能充电器。
本申请实施例中，通过步骤101的检测，判断充电器是否为高性能充电器，即通过判断充电器输出电压和输出电流是否满足快速充电的需求，若判断结果为是，则执行步骤103，若判断结果为否，则执行步骤105。
本申请实施例中，是否满足快速充电的需求的依据是，充电器的输出功率不小于18W，且输出电压不小于9V/输出电流不小于2A时，采用快速充电模式；充电器的输出功率小于18W，且输出电压小于9V/输出电流小于2A时，采用普通充电模式。
在步骤103，设置快速充电电池参数。
本申请实施例中，设置快速充电电池参数，主要包括电池最高耐受电压、电量满的门限电流、充电截止电流等参数。
本申请实施例中，电池参数，是根据电池规格书，再参考电池实际的充放电测试数据来确定的。普通充电的电池参数，主要是根据电池规格书和常规充电方案，选用常规的最高耐受电压，电量满的门限电流，和充电截止电流。快充充电的电池参数，是通过严格的电池充放电测试得到的，在保证安全的情况下，提高电池耐受电压，同时提高电量满的门限电流和充电截止电流，保证安全快速充电，并且电池实际充电容量基本不变。
在步骤104，对电池进行快速充电。
本申请实施例中，充电方式有恒流充电和恒压充电两种。恒流充电是电源通过调整充电电压，以固定的充电电流给电池充电。恒压充电是电源以固定的充电电压给电池充电，充电电流会逐步减小。
整个电池的充电过程可能会阶梯式地多次使用恒流充电和恒压充电，但充电的最后阶段，都是以恒压充电的方式给电池充电，这个最终的恒压充电的电压就是电池的最高耐受电压。
电池以最高耐受电压进行恒压充电的过程中，充电电流逐渐减小，减小到电量满门限电流值时，可以认为电池已充满，对用户显示电量100％。电量满时并不是立即彻底停止充电，而是继续充电，直到充电电流进一步减小至充电截止电流值，电池已经无法再充电时，此时切断充电电路，彻底停止充电。
本申请实施例中的快速充电工作方法是，在恒压充电阶段，电源以恒定的电压给电池充电，把这个电压提高一点，就可以提高充电的电流，同时相应的，要提高电量满的门限电流并提高充电截止电流，这样能够实现快速充电、不损失电量而且也不会导致电池过充的目的。
例如，普通充电时，电池充电参数为，最高恒压充电电压4.45V，电量满的门限电流 为400ma，充电截止电流为200ma，此时充满电的电量是4100mah左右，电量从1％到100％的时间是90分钟左右，充电截止时间是100分钟左右。而使用激进电池参数，我们可以设置最高恒压充电电压为4.5V，同时把电量满的门限电流设置为1.3A，充电截止电流设置为0.8A，实际截止充电的时候充入电池的电量为4050mah左右，充电满的时间70分钟左右，充电截止时间在80分钟左右。可以看到，两者实际充电电量基本相等，而充电时间却相差很大，用户体验相差很大。
在步骤105，设置普通充电电池参数。
本申请实施例中，经检测充电器为非高性能充电器时，进行普通充电电池参数的配置，参数主要来源于电池推荐参数。其主要包括电池最高耐受电压、电量满的门限电流、充电截止电流等参数。
在步骤106，对电池进行普通充电。
本申请实施例中，普通充电是指采用普通充电参数进行充电。
本申请实施例中的普通充电，当采用快速充电方式进行充电时，其与快速充电方式的区别仅仅在于不对电池最高耐受电压、电量满的门限电流、充电截止电流等参数进行超过额定标准的提高设置。
实施例2
图2为根据本申请实施例的快速充电装置结构示意图，如图2所示，本申请实施例的快速充电装置，包括，充电器能力检测单元201、充电模式选择单元202以及充电参数设置单元203。
其中，充电器能力检测单元201对充电器的充电能力进行检测，包括，对充电器进行类型的识别；再根据不同的充电器类型，进行输出能力探测，确定充电器的输出功率、输出电压、输出电流等参数范围。
充电模式选择单元202根据充电器能力的检测结果对充电模式进行选择。
本申请实施例中，充电模式选择单元202，依据检测结果判断充电器是否为高性能充电器，即判断充电器能力是否满足快速充电的需求，如果检测结果判断为高性能充电器，则确定电池选择快速充电模式，如果检测结果判断为非高性能充电器，则确定电池选择普通充电模式。
充电参数设置单元203根据充电模式的选择结果进行相应的充电参数设置。
本申请实施例中，充电方式有恒流充电和恒压充电两种。恒流充电是电源通过调整充电电压，以固定的充电电流给电池充电。恒压充电是电源以固定的充电电压给电池充电，充电电流会逐步减小。
整个电池的充电过程可能会阶梯式地多次使用恒流充电和恒压充电，但充电的最后阶 段，都是以恒压充电的方式给电池充电，这个最终的恒压充电的电压就是电池的最高耐受电压。
当电池采用快速充电模式时，分为两个充电阶段，第一阶段为交替的采用阶梯式恒流充电和恒压充电，第二阶段采用恒压充电的方式充电；当第一阶段电池的充电电压达到最高耐受电压时，进入第二阶段对所述电池进行充电。
第二阶段采用恒压充电，其电压为电池的最高耐受电压。
电池以最高耐受电压进行恒压充电的过程中，充电电流逐渐减小，减小到电量满门限电流值时，可以认为电池已充满，对用户显示电量100％。电量满时并不是立即彻底停止充电，而是继续充电，直到充电电流进一步减小至充电截止电流值，电池已经无法再充电时，此时切断充电电路，彻底停止充电。
本申请实施例中，选择快速充电模式时，进行快速充电参数设置，主要是对电池最高耐受电压、电量满的门限电流、充电截止电流等参数进行适当的提高。
选择普通充电模式时，进行普通充电参数设置，普通充电参数主要来源于电池推荐参数。
本申请实施例中的快速充电参数设置是，在恒压充电阶段，电源以恒定的电压给电池充电，把这个电压提高一点，就可以提高充电的电流，同时相应的，要提高电量满的门限电流并提高充电截止电流，这样能够实现快速充电、不损失电量而且也不会导致电池过充的目的。
本申请的一种快速充电方法及装置，检测到连接充电的充电器为高性能充电器时，进行快速充电参数设置，通过电池最高耐受电压、电量满的门限电流、充电截止电流等参数的提高，实现了在相同的硬件限制条件下，基本不损失可用电量的前提下，显著减少从开始充电到电量满的时间和从开始充电到截止充电时间，提高充电速度，提升用户体验。
虽然本申请所揭露的实施方式如上，但所述的内容仅为便于理解本申请而采用的实施方式，并非用以限定本申请。任何本申请所属领域内的技术人员，在不脱离本申请所揭露的精神和范围的前提下，可以在实施的形式及细节上进行任何的修改与变化，但本申请的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
