本发明的充电检测装置， 可应用于各种类型终端， 例如手机和桌面电 话等。 电信运营商仅需要对用户终端软件进行适当的修改， 例如通过增加 相应业务软件模块即可满足要求。
基于上述的充电检测装置， 本发明还提供了一种充电检测的方法， 下 面结合具体实施例和附图来详细说明。
如图 3 所示， 本发明的一种电池充电检测的方法的一种实施例中， 该 方法包括以下步骤：
步骤 Sl、 预先设置当前充电电池的充电参数， 包括满充电电压、 充电 临界电压和最大充电时间， 以及检测参数， 包括预设检测时间、 釆样周期 和次数。
在本发明的一种实施例中， 充电参数和检测参数可以根据当前充电电 池的特性来设置。 其中， 满充电电压设置的比电池的充电截止电压略小； 充电临界电压设置为充电截止电压的 80%到 90% 左右，并且小于设定的满 充电电压， 额定充电时间为按照电池容量和充电器输出电流计算得到的时 间， 最大充电时间则设置为额定充电时间的两倍左右， 例如电池容量为 lOOOmAh, 充电器的输出电流是 500mA, 则此时的充电所需的时间应为 1000mAh/500mA=2小时， 则最大充电时间则为四小时， 当然最大充电时间 也可以根据充电电池的特征设置为其他值； 其中， 预设的检测时间不能够 太长， 否则会产生过充电的情况， 例如设置为 1 分钟左右； 检测釆样周期 不应设置过长，例如不超过 5分钟为宜，则相应的釆样次数可设定为 30次， 每次间隔 10s进行。
步骤 S2、 检测当前充电电池的电压。
步骤 S3、 比较所检测的电压是否大于等于设置的满充电电压， 如是， 则执行步骤 S4。
步骤 S4、 经过预设检测时间后， 判断检测得到的该电池的电压是否仍 然大于等于满充电电压， 如是， 则确定为正常充电； 否则， 执行步骤 S5。
步骤 S5、 按照预设的检测周期和次数， 釆样电池的电压。
步骤 S6、 比较所釆样的电压是否都大于充电临界电压， 如是， 则执行 步骤 S7, 否则， 继续充电。
步骤 S7、 判断所釆样得到的电压是否呈单调递增的趋势， 如是， 则确 定正常充电； 否则， 执行步骤 S8。 长趋势、 折线增长趋势或者曲线增长的趋势， 当然也可以是其他增长趋势。 即是说所釆样得到的电压只要满足都大于充电临界电压， 并且每一次釆集 的电压都大于等于前一次所釆集的电压， 则确定为正常充电。
步骤 S8、 获取电池当前的充电时间， 得到第一充电时间， 并比较获取 的第一充电时间是否大于电池的额定充电时间， 如是， 则确定为第一充电 故障， 并结束充电， 同时提示用户该电池不能够充满， 否则， 继续充电。
这里的电池的当前充电时间即为电池从开始充电到对该电池进行最后 一次釆样的这一段时间。
由于电池的老化或者使用了不匹配的充电器， 因此， 有时会出现充电 已经结束但是却没有充满电的情况。 本方法通过检测当前充电电池电压及 其充电时间， 并将其分别与预先设置的充电临界电压和额定充电时间进行 比较： 当电池的电压大于充电临界电压， 而充电时间不大于额定充电时间， 或者电池的电压不大于充电临界电压， 而充电时间大于额定充电时间， 或 者电池的电压不大于充电临界电压， 并且充电时间不大于额定充电时间时， 让电池继续充电， 避免了充电结束而没有充满的现象； 当电池的电压大于 充电临界电压， 并且充电时间大于额定充电时间时， 则确定为第一充电故 障， 并结束充电， 同时提示用户出现充电故障， 避免了当充不满电， 却不 能够结束充电也没有提示的现象。
有时由于电池本身或者充电器出现了故障， 导致电池充电时间很长却 并不能充满。 本发明还釆用通过检测电池的充电时间， 并将其与最大充电 时间相比较， 当其充电时间达到最大充电时间时， 即结束充电， 从而避免 长时间充电， 而充不满的现象， 如图 4所示， 本发明的方法的另一种实施 例中包括以下步骤：
步骤 S21、预先设置当前充电电池的充电参数和检测参数，该充电参数 包括满充电电压、 充电临界电压和最大充电时间， 检测参数包括预设检测 时间、 釆样周期和次数。
步骤 S22、 检测当前充电电池的电压。
步骤 S23、 比较所检测的电压是否大于等于设置的满充电电压， 如是， 则执行步骤 S4。 步骤 S24、 比较经过预设检测时间后，检测得到的该电池的电压是否仍 然大于等于满充电电压， 如是， 则确定为正常充电； 否则， 执行步骤 S25。
步骤 S25、 按照预设的检测周期和次数， 釆样电池的电压。
步骤 S26、 比较所釆样的电压是否都大于充电临界电压， 如是， 则执行 步骤 S27 , 否则获取电池当前的充电时间， 得到第二充电时间， 并执行步骤 S29。
这里的电池的当前充电时间即为电池从开始充电到对该电池进行最后 一次釆样的这一段时间。
步骤 S27、 判断所釆样得到的电压是否呈单调递增的趋势， 如是， 则确 定为正常充电； 否则， 执行步骤 S28。
步骤 S28、 获取电池当前的充电时间， 得到第一充电时间， 并比较获取 的第一充电时间是否大于电池的额定充电时间， 如是， 则确定发生第一充 电故障， 并结束充电， 同时提示用户发生第一充电故障， 该电池不能够充 满， 否则， 继续充电。
步骤 S29、 比较第二充电时间是否大于等于最大充电时间， 如是， 则确 定发生第二充电故障， 结束充电， 并提示用户发生第二充电故障， 该电池 异常或充电器异常， 否则继续充电。
本发明的方法通过检测充电电池的电压和充电时间， 并将其与满充电 电压和充电临界电压进行比较， 以及通过检测充电电池的充电时间， 并将 其分别与额定充电时间和最大充电时间相比较， 当电池的充电电压大于充 电临界电压， 并且其第二充电时间大于等于最大充电时间时， 确定为第二 充电故障， 并控制结束充电， 同时提示用户发生充电故障。 本实施例的方 法不仅能够检测出电池充电过程中的故障， 更能有效地避免电池或者充电 器异常时不能及时结束充电并提示用户异常的问题。
以上内容是结合具体的实施方式对本发明所作的进一步详细说明， 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的 普通技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干简单 推演或替换， 都应当视为属于本发明的保护范围。
