附图说明
为了更清楚地说明本申请实施例的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其它的附图。

具体实施方式
为了更好的理解本申请的技术方案，下面结合附图对本申请实施例进行详细描述。
应当明确，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
应当理解，本文中使用的术语“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
应当理解，尽管在本申请实施例中可能采用术语第一、第二来描述指定数值，但这些指定数值不应限于这些术语。这些术语仅用来将指定数值彼此区分开。例如，在不脱离本申请实施例范围的情况下，第一指定数值也可以被称为第二指定数值，类似地，第二指定数值也可以被称为第一指定数值。
取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”或“响应于检测”。类似地，取决于语境，短语“如果确定”或“如果检测(陈述的条件或事件)”可以被解释成为“当确定时”或“响应于确定”或“当检测(陈述的条件或事件)时”或“响应于检测(陈述的条件或事件)”。
由于未发生短路的电池的电阻为一个定值，发生短路的电池的电阻为一个变值。当确定充电方式后，在通过为电池充电来检测电池是否发生短路时，未发生短路的电池的充电电压和充电电流对应的波形的峰值数目为一个固定的数值，或者未发生短路的电池的充电电压和/或充电电流对应的数值中的峰值数目为一个固定的数值，而发生短路的电池的充电电压和充电电流对应的波形的峰值数目是大于该固定数值的，或者发生短路的电池的充电电压和充电电流对应的数值中的峰值数目是大于固定数值的，因此可以通过充电电压和/或充电电流对应的波形的峰值数目，或者是通过充电电压和/或充电电流对 应的数值中的峰值数目来检测电池是否短路。
本申请实施例中，以脉冲充电的方式为电池进行充电为例，对检测电池是否发生短路的实现方案进行举例说明。脉冲充电的方式可以为：使用恒定电流为电池进行恒流充电，然后使用恒定电压为电池进行恒压充电。
如图1a所示，为未发生短路的电池的电压形成的波形示意图。在电池未发生短路时，通过上述方法充电时，该电池的电压形成的波形图对应一个波峰。
如图1b所示，为未发生短路的电池的电流形成的波形示意图。在电池未发生短路时，通过上述方法充电时，该电池的电流形成的波形图对应一个波峰。
如图2a所示，为发生短路的电池的电压形成的波形示意图。在电池发生短路时，通过上述方法充电时，该电池的电压形成的波形图对应的波峰的数目大于1。
如图2b所示，为发生短路的电池的电流形成的波形示意图，在电池发生短路时，通过上述方法充电时，该电池的电流形成的波形图对应的波峰的数目大于1。
在出现测试环境或检测装置自身等问题对测试产生影响时，充电电压和/或充电电流也会随之产生变化，此时，产生的充电电压和/或充电电流对应的数值中的峰值数目会大于固定数值，或者充电电压和/或充电电流对应的波形的峰值数目大于固定数值，且电压和电流形成的波形图与电池发生短路时形成的波形图类似。
由于短路电池、测试环境问题和检测装置自身问题都会引起上述变化，即能够引起上述变化的原因包括两方面，一方面是因为电池自身为短路电池，另一方面为测试环境和检测装置自身问题引起的，因此，当出现目标数据中状态数据对应的波形的峰值数目或者状态数据对应的数值中的峰值数目大于该定值的情况时，将该电池检测为短路电池，从而避免由于测试环境或检测装置自身等问题，将短路电池检测为未短路电池的情况。

具体的，在输出目标数据后，可以使用户直观的看到待测试电池对应的目标数据，用户可以根据该目标数据中的状态数据对应的波形的峰值数目或者状态数据对应的数值中的峰值数目来人工判断该电池是否为短路电池。
另外，为了生产或者记录数据的需要，还可以对目标数据进行存储，这样就可以在需要目标数据时可以从存储空间中读取目标数据。
在本申请实施例中，在对待检测电池进行充电的过程中，获取待检测电池的状态数据，如电压信号和/或电流信号，然后根据获取的状态数据，获取对应的目标数据，如状态数据对应的波形的峰值数目或者状态数据对应的数值中的峰值数目。由于当待检测电池未发生短路时，状态数据对应的波形的峰值数目或者状态数据对应的数值中的峰值数目为一个定值，当待检测电池为发生短路时，状态数据对应的波形的峰值数目或者状态数据对应的数值中的峰值数目大于该定值，因此，可以通过目标数据来检测待检测电池是否发生短路。而且，由于当出现测试环境或检测装置自身等问题对测试产生影响时，获取的电压信号和/或电流信号也会随之产生变化，使得目标数据中状态数据对应的波形的峰值数目或者状态数据对应的数值中的峰值数目大于该定值。由于短路电池、测试环境问题和检测装置自身问题都会引起上述变化， 即能够引起上述变化的原因包括两方面，一方面是因为电池自身为短路电池，另一方面为测试环境和检测装置自身问题引起的，即测试环境问题和检测装置自身问题会对目标数据中状态数据对应的波形的峰值数目或者状态数据对应的数值中的峰值数目产生影响，因此，当出现目标数据中状态数据对应的波形的峰值数目或者状态数据对应的数值中的峰值数目大于该定值的情况时，将该电池检测为短路电池，从而避免由于测试环境或检测装置自身等问题，将短路电池检测为未短路电池的情况。
