本发明的实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
本发明实施例中，需要在电子终端中额外设置一套温控方法来对电池保护，电子设备由电源适配器供电时，电池长时间会处于高温高压(满电)环境会导致膨胀的风险；在高温场景下，当电池温度大于等于电池的停冲门限温度时，系统会停止对电池充电；当温度大于等于关机门限温度时，使系统自动关机。
本发明实施例中，为对终端中电池进行保护，设置有高温关机门限值T1，及高温电池停冲门限值T2，高温安全存储阈值T3的设定和判定控制，其中T1＞T3≥T2。
检测电池温度，当电池温度>高温关机门限值T1时，终端中的操作系统 关机；
检测电池温度，当电池温度小于高温电池停冲门限值T2时，终端中的操作系统进入正常的充电流程，对电池进行充电；
当电池温度大于等于高温安全存储阈值T3，而小于高温关机门限值T1时，电池停止充电，并判断电池电压，当电池电压大于所设定高温安全电压门限时(该安全电压可设定为电池电量80％以下某电量的电池电压)，将适配器供电切换至电池供电，对电池进行放电，当电池放电至安全电压后，再切换回适配器供电。
本发明实施例中，以T2为45℃，T1为60℃为例进行说明。例如：根据T2、T1，把高温安全存储阈值T3设为48℃，高温安全电压设为3.9V，一旦电池温度高于48℃，切换供电，断开适配器供电，使用电池支路供电，对电池放电，当电池电压放电至安全电压3.9V以下后，恢复适配器供电,通过此方法可有效规避电池长时间高温高压存储风险。
以下通过具体示例，进一步阐明本发明实施例的技术方案的实质。
图1为本发明实施例一的电池保护方法的流程示意图，如图1所示，本示例的电池保护方法包括以下步骤：
步骤101，检测到电池温度大于高温安全存储阈值T3，且小于高温关机门限值T1时，判断电池的当前电力参数是否满足第一设定条件，满足第一设定条件时，执行步骤102；
本发明实施例中，在适配器供电的情形下，对电池的温度进行检测。如果由电池对终端进行供电，则电池处于放电状态，不会导致电池过充及高温的情形。
本发明实施例中，所述电力参数为电压；对应地，所述判断电池的当前电力参数是否满足第一设定条件，包括：
判断电池的当前电压是否大于所设定的安全电压门限，当前电压大于所设定的安全电压门限时，满足第一设定条件。
所述电力参数也可以为电量；对应地，所述判断电池的当前电力参数是否满足第一设定条件，包括：
判断电池的当前电量是否大于所设定的安全电量门限，当前电量大于所设定的安全电量门限时，满足第一设定条件。
本发明实施例中，检测到电池温度大于等于高温关机门限值时，关闭当前的操作系统；
检测到电池温度大于等于高温电池停冲门限值时，判断当前是否对电池进行充电，如果为是，则停止对电池充电。
检测到电池温度小于高温电池停冲门限值时，判断当前是否对电池进行充电，未进行充电时，对电池进行充电。
步骤102，当前的供电模式由适配器供电转换为由电池供电，对电池进行放电；
本发明实施例中，设定高温安全存储阈值及高温关机门限值，该高温安全存储阈值大于高温电池停冲门限值，且小于高温关机门限值。也就是说，尽量避免电池处于大于高温安全存储阈值，且小于高温关机门限值的状态，避免电池长时间处于不利环境而出现漏液等现象。
步骤103，判断放电电池的当前电力参数是否满足第二设定条件，满足第二设定条件时，执行步骤104；
本发明实施例中，所述电力参数为电压；对应地，所述判断放电电池的当前电力参数是否满足第二设定条件，包括：
判断放电电池的当前电压是否小于等于所设定的安全电压门限，当前电压小于等于所设定的安全电压门限时，满足第二设定条件。
本发明实施例中，所述电力参数为电量；对应地，所述判断放电电池的当前电力参数是否满足第二设定条件，包括：
判断放电电池的当前电量是否小于等于所设定的安全电量门限，当前电量小于等于所设定的安全电量门限时，满足第二设定条件。
步骤104，将当前的供电模式由电池供电切换回由适配器供电。
终端在电池的电量或电压分别低于安全电压门限或安全电量门限时，将控制当前的供电模式由电池供电切换回由适配器供电。
图2为本发明实施例二的电池保护方法的流程示意图，如图2所示，本示例的电池保护方法包括以下步骤：
步骤S201：对终端以适配器进行供电；
步骤S202：用户进行开机操作，终端启动开机流程；
步骤S203：终端获取电池温度值t；
步骤S204：终端判断电池温度t，当t>高温关机门限值T1时，设备进入关机流程，设备关机，等待用户开机；否则执行步骤S205；
步骤S205：终端判读电池温度t，当t≥高温电池停冲门限值T2时，执行步骤S206，否则进入正常的电池充电流程，充电结束后执行步骤S203；
步骤S206：终端控制当前供电模式，停止对电池进行充电操作；
步骤S207：终端判读电池温度t，当t≥高温安全存储阈值T3时，执行步骤S208，否则返回至步骤S203；
步骤S208：终端采样电池电压值v；
步骤S209：终端判读电池电压v，当v≥高温安全存储电压阈值V1时，执行步骤S210，否则执行步骤S211；
步骤S210：终端控制当前供电模式由适配器供电切换至电池供电，对电池放电，并继续跳转至步骤S208，检测电池电压，直到电池放电至高温安全存储电压阈值以下；
步骤S211：终端通过控制信号控制当前供电模式切换至适配器供电，断开电池供电，返回步骤S203。
上述实施例中，当高温电池停冲门限值和高温安全存储阈值设置为同一温度值时，如图3所示，实现流程包括以下步骤：
步骤S301：终端由适配器供电；
步骤S302：用户进行开机操作，终端启动开机流程；
步骤S303：终端获取电池温度值t；
步骤S304：终端判断电池温度t，当t>高温关机门限值T1时，设备进入关机流程，设备关机，等待用户开机；否则执行步骤S305；
步骤S305：终端判读电池温度t，当t≥高温电池停冲门限值T2(即高温安全存储阈值)时，执行步骤S306，否则进入正常的电池充电流程，充电结束后执行步骤S303；
步骤S306：终端控制当前供电模式，停止对电池进行充电操作；
步骤S307：终端采样电池电压值v；
步骤S308：终端判读电池电压v，当v≥高温安全存储电压阈值V1时，执行步骤S309，否则执行步骤S310；
步骤S309：终端控制当前供电模式由适配器供电切换至电池供电，对电池放电，并继续跳转至步骤S308，检测电池电压，直到电池放电至高温安全电压存储阈值以下；
步骤S310：终端通过控制信号控制当前供电模式切换至适配器供电，断开电池供电，返回步骤S303。
本发明实施例中的高温安全存储阈值T3的设定，要求大于等于高温电池停冲门限值，以确保保护电池高温充电的同时规避电池高温高压存储的风险，另根据大多数电池温度膨胀系数曲线，电池在45℃以上，膨胀率开时增大，在50℃以上时，膨胀率急剧增大，故高温安全存储阈值设置为45℃～50℃区间内是一个比较合理的阈值范围。
根据电池放电曲线，任何电池的电量和电池电压有着一定对应关系，因此上述实施例中，对于安全存储电压阈值的判断和设定可以用电池电量来替换，这里称为高温存储安全电量阈值，图4为本发明实施例四的电池保护方法的流程示意图，如图4所示，本示例的电池保护方法包括以下步骤：
步骤S401：终端在由适配器供电；
步骤S402：用户进行开机操作，终端启动开机流程；
步骤S403：终端获取电池温度值t；
步骤S404：终端判断电池温度t，当t>高温关机门限值T1时，设备进入关机流程，设备关机，等待用户开机；否则执行S405步骤；
步骤S405：终端判读电池温度t，当t≥高温电池停冲门限值T2时，执行步骤S406，否则进入正常的电池充电流程，充电结束后执行步骤S403；
步骤S406：终端控制当前供电模式，对电池进行充电操作；
步骤S407：终端判读电池温度t，当t≥高温安全存储阈值T3时，执行步骤S408，否则返回至步骤S403；
步骤S408：终端采样电池电量值q；
步骤S409：终端判读电池电量q，当q≥高温安全存储电量阈值Q1时，执行步骤S410，否则执行步骤S411；
步骤S410：终端控制当前供电适配器供电，切换至电池供电，对电池放电，并继续跳转至步骤S408，检测电池电压，直到电池放电至高温安全存储电压阈值以下；
步骤S411：终端控制当前供电模式切换至适配器供电，断开电池供电，返回步骤S403。
