Description

终端充电控制方法、装置及终端 技术领域
本申请涉及但不限于电子技术领域。
背景技术
在移动终端的发展历程中，很长一段时期内都存在“备用电池”的概念，备用电池是为移动终端配置一块可外置充电的电池，其主要目的是为了延长移动终端的使用时长。但随着移动终端电源的发展，已经能够在体积较小的电池中储蓄足够多的电能，因而在后续的发展过程中备用电池因为携带不便等问题被逐渐淘汰，相关技术的移动终端中普遍都是采用一块电池为***供电。
虽然在移动终端上配置一块电池进行供电能够解决备用电池携带不便的问题，但是这也带来了新的问题：在存在备用电池时，移动终端的充电过程可以在移动终端外完成，当充电完成之后再将电池安装到移动终端中为***供电，这样充电过程中的噪声与杂波不会影响到移动终端的***。但是当移动终端仅配置一块电池时，该电池在充电的同时还不得不承担为***供电的责任，因此电源适配器、充电芯片、充电路径上的噪声和杂波在叠加后会被引入到移动终端***中，从而影响***的可靠性和稳定性。
虽然相关技术的移动终端在电量过低的时候，可以由外部供电电源直接为***供电，保证***处于运行状态，但是由于外部供电电源可能会存在不稳定的情况，例如外部供电电源带来的负向浪涌或者瞬时高压的状况，会极大地影响***的稳定性，威胁到移动终端的安全。所以在只有一块电池的情况下，充电过程中由外部供电电源直接为移动终端***长期供电也不是一个好的做法，应当尽量避免。
综上，亟需提出一种终端充电控制方案，用以解决相关技术中仅设置一块电池为移动终端供电，而导致在同时充电与供电时容易将充电的噪声通过供电引入到移动终端***中，从而影响到移动终端***的可靠性与稳定性的问题。

详述
下文中将结合附图对本发明的实施方式进行详细说明。需要说明的是，在不冲突的情况下，本文中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸根据一组计算机可执行指令的计算机***中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
为了解决相关技术中仅为终端设置一块电池而导致的充电时候容易将充电噪声引入终端***，影响终端***可靠性与稳定性的问题，本发明实施例提供一种终端充电控制方法，如图1所示，为本发明实施例提供的一种终端充电控制方法的流程图，该方法可以通过终端充电控制装置运行，该方法包括如下步骤，即S110～S120：
S110，从终端电池中选择当前待充电电池和当前供电电池。
由于相关技术的问题在于仅设置了一块电池，因此这块电池在进行充电 的同时也要对终端***供电，以保证终端***处于运行状态。这就导致了充电与供电两个过程相互关联，供电的时候容易将充电侧的噪声、杂波等引入终端***，从而对终端***造成影响。充电侧的噪声或者杂波主要是由于电源适配器、充电芯片以及充电路径造成的，无论花费多大的代价来设计完善电源适配器、充电芯片和充电路径，这三个器件带来的噪声和杂波是不可杜绝的。而相关技术的电池充电无法脱离这三个器件单独进行，也就是说相关技术还无法从噪声源头杜绝噪声。因此，为了避免这些噪声或杂波被引入***中，只能设法将充电与供电两个过程进行分离。
虽然在终端电池电量极低，无法保证***运行的场景中，相关技术中能够通过外部供电电源直接为终端***供电，这时候，终端***的供电和电池充电两个过程是分离的。但是由于外部供电电源不稳定，会对终端***的安全性造成极大的负面影响，例如外部供电电源供电时所产生的负向浪涌可能会导致终端***掉电，而瞬时高压甚至会让终端产生不可逆的损害，因此在能够避免直接由外部供电电源供电的情况下尽量不使用外部供电电源供电已经成了业界共识，所以，相关技术只能在保证终端安全性的前提下忍受着电池充电给***带来的噪声。
可选地，本发明实施例提供的终端充电控制方法适用于配置有多块电池的终端，假定终端配置有N个电池，N为大于或等于2的整数，这N个电池都是配置有充电功能的电池，常见的可充电电池包括锂电池和镍氢电池。可选地，这N个电池可以都是锂电池或者镍氢电池，也可以是锂电池和镍氢电池以任意的占比进行组合构成。在充电的同时，一般会有供电电源为终端的***供电，保证***正常运行。因此，在进行充电之前可以先选择出用于供电的当前供电电池和用于充电的当前待充电电池。
可选地，在本发明实施例中，选择当前待充电电池的时候可以根据充电条件进行选择，充电条件可以为预先设置的，例如：选择当前电量最低的M个电池为当前待充电电池，在实际应用中，M可以为大于0的整数。可选地，充电条件也可以是电量低于预设阈值的电池。在上述两种充电条件的情况下，选择机制是不同的，第一种是由终端***的开发人员或者是用户预先设置选择个数，则最终选择出的当前待充电电池的个数是一定的；而第二种是 预先设置了成为当前待充电电池的条件，选择出来的当前待充电电池的个数不定。
可选地，在本发明实施例中，终端充电控制装置选择当前供电电池的时候，可以从终端的N个电池中选择出其中电压值大于第一预设阈值的电池作为当前供电电池，第一预设阈值是能够为终端供电的最低电压，也就是说，第一预设阈值表示该当前供电电池处于低电量状态。
在实际应用中，如果本发明实施例中终端充电控制装置即为终端本身，那么在实施该方法的时候，终端***可能需要处于运行状态，也就是说需要在选择出当前供电电池之前就提供电源供终端***开始运行，为此，可以采用相关技术中的方式，让外部供电电源短暂的为终端***供电；也可以在终端内部设置一个临时电池，如可更换的纽扣电池等。临时电池平时不使用，仅在确定终端需要充电，到终端确定出当前供电电池的期间内为终端***供电。本发明实施例描述的***处于运行状态并不是指开机状态，是指终端***控制某些进程的状态，但是此时呈现给用户的界面可能依然是关机状态。
S120，对当前待充电电池进行充电，并且通过当前供电电池为终端的***供电。
可选地，在本发明实施例中，将第一预设阈值作为选择因素选择出来的当前供电电池的数目例如为K个，K为大于或等于0的整数；在选择K个电池作为当前的供电电池之前，本发明实施例提供的方法还可以包括：控制外部供电电源与***供电接口连通为该终端供电。
在本发明实施例的一个应用场景中，当K大于0的时候，表征出当前可以直接由终端配置有充电功能的电池来为终端供电，保证***运行；该应用场景下，本发明实施例提供的方法还可以包括：控制断开外部供电电源与***供电接口之间的电连接。在实际应用中，可以将终端的供电电源切换为供电电池，如果之前是由外部供电电源直接与终端***的供电接口连接，那么此时可以断开***供电接口与外部供电电源之间的电连接，而将选择出的当前供电电池与***供电接口连通。
在本发明实施例的一个应用场景中，如果终端所有电池的电压值都低于第一预设阈值，则无法选择出当前供电电池为终端***供电，即K等于0， 在这种情况下，在当前待充电电池充电电量超过第一预设阈值之前依旧可以采用外部供电电源或者是终端临时电池来供电。
在实际应用中，由于终端在充电期间，无论是处于充电状态的当前待充电电池还是处于供电状态的当前供电电池，其电量都在变化，当这种变化到达一定程度的时候，一些电池就不适合再做当前待充电电池或者当前供电电池了。例如，在当前待充电电池充电完成之前，当前供电电池的电压值已经低于第一预设阈值，无法继续为终端供电，如果不更换当前供电电池，终端***分将不能继续运行，所以尽管此时当前待充电电池的充电没有完成，但是只要当前待充电电池的电压高于第一预设阈值，则应当将当前待充电电池切换为当前供电电池，而当前供电电池也应当被切换为当前待充电电池进行充电。另外，如果当前待充电电池的电量持续增长，但是当前供电电池的电压一直在第一预设阈值之上，那么在当前待充电电池充电完成之后，也应当将当前待充电电池切换为当前供电电池，将当前供电电池切换为当前待充电电池。
可选地，图2为本发明实施例提供的另一种终端充电控制方法的流程图。在本发明上述实施例中的基础上，为了让终端充电控制装置根据每个电池电量的情况做出即时的切换动作，本发明实施例提供的终端充电控制方法还可以包括如下步骤，即S130～S150：
S130，对终端电池的电压进行监测。
监测对象包括当前供电电池与当前待充电电池，对于这两者的监测没有严格时序限制，在实际应用中，可以在选择出当前待充电电池与当前供电电池的时候，终端充电控制装置就对当前待充电电池和当前供电电池的电压分别进行监测。
S140，当监测到当前供电电池的电压满足第一预设切换条件时，断开满足第一预设条件的每个当前供电电池与***供电接口之间的电连接，并从当前待充电电池中重新选择供电电池为终端供电。
当前供电电池的电压满足第一预设切换条件，表示当前供电电池不再适合为终端供电，对于当前供电电池不再适合供电的情况，终端充电控制装置可以从当前待充电电池中重新选择供电电池为终端供电。
可选地，在本发明实施例中，第一预设切换条件可以包括：当前供电电池的电压值小于或等于第一预设阈值，该第一预设阈值表示当前供电电池处于低电量状态。如果当前待充电电池的电压值也满足第一预设切换条件，则说明当前待充电电池也不适合供电，这时候，终端充电控制装置还可以从当前既不是待充电电池，又不是供电电池的那些电池中选择供电电池，或者可以采用外部供电电源继续为终端供电，直至当前待充电电池的电量高于第一预设阈值的时候再切换成由当前待充电电池供电。
S150，当监测到当前待充电电池的电压满足第二预设切换条件时，将满足第二预设切换条件的每个当前待充电电池切换为当前供电电池，并从当前未进行充电的N-M个电池中重新选择待充电电池。
可选地，在本发明实施例中，第二预设切换条件可以包括：当前待充电电池的电压值大于或等于第二预设阈值，该第二预设阈值表示当前待充电电池充电完成。虽然第二预设阈值表示充电完成，但是这并不意味着终端的电量为100％，因为第二预设阈值可以是由开发人员在设置开发终端设置的，也可以是由用户自定义设置的，例如开发人员或者用户人为地设置电池电量大于96％就表征充电完成，虽然电池此时还可以继续充电，但是在本发明实施例中，当当前待充电电池的电量大于96％的时候就可以将其切换为当前供电电池，并从当前充电未完成的电池中重新选择待充电电池。在实际应用中，选择的范围可以是当前供电电池，也可以是既不是当前待充电电池也不是当前供电电池的那些电池。
本发明实施例提供的终端充电控制方法，通过对同一时刻的当前待充电电池与当前供电电池进行区分，保证对一块电池进行充电的时候该电池不需要同时为终端供电，因此，有效地避免了对当前待充电电池进行充电的噪声或者杂波通过供电引入终端***的问题，提高了终端***的可靠性与稳定性，保证了终端的安全，提高了用户体验。
另外，本发明实施例提供的终端充电控制方法，通过对当前供电电池的电压进行监测，如果发现当前供电电池的电压值满足第一预设切换条件时，可以重新选择当前供电电池，在当前供电电池电量不足，无法继续供电的时候，能够通过切换其他电池作为供电电池保证终端***继续运行。另一方面， 本发明实施例提供的终端充电控制方法，还通过对当前待充电电池的电压值进行监测，在发现当前待充电电池充电完成之后立即切换到位其他电池进行充电，避免浪费充电时间，提高充电效率。
本发明实施例还提供一种终端充电控制装置，该装置可以用于执行本发明上述实施例提供的终端充电控制方法。如图3所示，为本发明实施例提供的一种终端充电控制装置的结构示意图，本发明实施例提供的终端充电控制装置20可以包括：选择模块210和控制模块220。
其中，选择模块210，设置为：从终端电池中选择当前待充电电池和当前供电电池。
由于相关技术的问题在于仅设置了一块电池，因此这块电池在进行充电的同时也要对终端***供电，以保证终端***处于运行状态。这就导致了充电与供电两个过程相互关联，供电的时候容易将充电侧的噪声、杂波等引入终端***，从而对终端***造成影响。充电侧的噪声或者杂波主要是由于电源适配器、充电芯片以及充电路径造成的，无论花费多大的代价来设计完善电源适配器、充电芯片和充电路径，这三个器件带来的噪声和杂波是不可杜绝的。而相关技术的电池充电无法脱离这三个器件单独进行，也就是说相关技术还无法从噪声源头杜绝噪声。因此，为了避免这些噪声或杂波被引入***中，只能设法将充电与供电两个过程进行分离。
虽然在终端电池电量极低，无法保证***运行的场景中，相关技术中能够通过外部供电电源直接为终端***供电，这时候，终端***的供电和电池充电两个过程是分离的。但是由于外部供电电源不稳定，会对终端***的安全性造成极大的负面影响，例如外部供电电源供电时所产生的负向浪涌可能会导致终端***掉电，而瞬时高压甚至会让终端产生不可逆的损害，因此在能够避免直接由外部供电电源供电的情况下尽量不使用外部供电电源供电已经成了业界共识，所以，相关技术只能在保证终端安全性的前提下忍受着电池充电给***带来的噪声。
可选地，本发明实施例提供的终端充电控制装置20适用于配置有多块电池的终端，假定终端配置有N个电池，N为大于或等于2的整数，这N个 电池都是配置有充电功能的电池，常见的可充电电池包括锂电池和镍氢电池。可选地，这N个电池可以都是锂电池或者镍氢电池，也可以是锂电池和镍氢电池以任意的占比进行组合构成。在充电的同时，一般会有供电电源为终端的***供电，保证***正常运行。因此，在进行充电之前，选择模块210可以先选择出用于供电的当前供电电池和用于充电的当前待充电电池。
可选地，在本发明实施例中，选择模块210选择当前充电电池的时候可以根据充电条件进行选择，充电条件可以为预先设置的，例如：选择当前电量最低的M个电池为当前待充电电池，在实际应用中，M可以为大于0的整数。可选地，充电条件也可以是电量低于预设阈值的电池。在上述两种充电条件的情况下，选择机制是不同的，第一种是由终端***的开发人员或者是用户预先设置选择个数，则最终选择出的当前待充电电池的个数是一定的；而第二种是预先设置了成为当前待充电电池的条件，选择出来的当前待充电电池的个数不定。
可选地，在本发明实施例中，选择模块210选择当前供电电池的时候，可以从终端的N个电池中选择出其中电压值大于第一预设阈值的电池作为当前供电电池，第一预设阈值是能够为终端供电的最低电压，也就是说，第一预设阈值表示该当前供电电池处于低电量状态。
在实际应用中，如果本发明实施例中终端充电控制装置20部署在终端上，那么在实施该方法的时候，终端***可能需要处于运行状态，也就是说需要在选择出当前供电电池之前就提供电源供终端***开始运行，为此，可以采用相关技术中的方式，让外部供电电源短暂的为终端***供电；也可以在终端内部设置一个临时电池，如可更换的纽扣电池等。临时电池平时不使用，仅在确定终端需要充电，到终端确定出当前供电电池的期间内为终端***供电。本发明实施例描述的***处于运行状态并不是指开机状态，是指终端***控制某些进程的状态，但是此时呈现给用户的界面可能依然是关机状态。
控制模块220，设置为：对选择模块210选择的当前待充电电池进行充电，并通过选择模块210选择的当前供电电池为终端的***供电。
可选地，在本发明实施例中，将第一预设阈值作为选择因素选择出来的 当前供电电池的数目例如为K个，K为大于或等于0的整数；在选择K个电池作为当前的供电电池之前，本发明实施例提供的装置20中，控制模块220，还设置为：控制外部供电电源与***供电接口连通为该终端供电。
在本发明实施例的一个应用场景中，当K大于0的时候，表征出当前可以直接由终端配置有充电功能的电池来为终端供电，保证***运行；该应用场景下，本发明实施例提供的控制模块220，还设置为：控制断开外部供电电源与***供电接口之间的电连接。在实际应用中，控制模块220可以将终端的供电电源切换为供电电池，如果之前是由外部供电电源直接与终端***的供电接口连接，那么此时控制模块220可以断开***供电接口与外部供电电源之间的电连接，而将选择出的当前供电电池与***供电接口连通。
在本发明实施例的另一个应用场景中，如果终端所有电池的电压值都低于第一预设阈值，则无法选择出当前供电电池为终端***供电，即K等于0，在这种情况下，在当前待充电电池充电电量超过第一预设阈值之前依旧可以采用外部供电电源或者是终端临时电池来供电。
在实际应用中，由于终端在充电期间，无论是处于充电状态的当前待充电电池还是处于供电状态的当前供电电池，其电量都在变化，当这种变化到达一定程度的时候，一些电池就不适合再做当前待充电电池或者当前供电电池了。例如，在当前待充电电池充电完成之前，当前供电电池的电压值已经低于第一预设阈值，无法继续为终端供电，如果不更换当前供电电池，终端***分将不能继续运行，所以尽管此时当前待充电电池的充电没有完成，但是只要当前待充电电池的电压高于第一预设阈值，则应当将当前待充电电池切换为当前供电电池，而当前供电电池也应当被切换为当前待充电电池进行充电。另外，如果当前待充电电池的电量持续增长，但是当前供电电池的电压一直在第一预设阈值之上，那么在当前待充电电池充电完成之后，也应当将当前待充电电池切换为当前供电电池，将当前供电电池切换为当前待充电电池。
可选地，图4为本发明实施例提供的另一种终端充电控制装置的结构示意图。在本发明上述实施例中的结构基础上，为了根据每个电池电量的情况做出即时的切换动作，本发明实施例提供的终端充电控制装置20除了包括 选择模块210和控制模块220以外，还可以包括：监测模块230。
其中，监测模块230，设置为：对终端电池的电压进行监测。
监测模块230监测对象包括当前供电电池与当前待充电电池，对于这两者的监测没有严格时序限制，在实际应用中，可以在选择出当前待充电电池与当前供电电池的时候，监测模块230就对当前待充电电池和当前供电电池的电压分别进行监测。
本发明实施例中的控制模块220，还设置为：当监测模块230监测到当前供电电池的电压满足第一预设切换条件时，断开满足第一预设条件的每个当前供电电池与***供电接口之间的电连接，并从当前待充电电池中重新选择供电电池为终端供电。
当前供电电池的电压满足第一预设切换条件，表示当前供电电池不再适合为终端供电，对于当前供电电池不再适合供电的情况，监测模块230可以通知控制模块220可以从当前待充电电池中重新选择供电电池为终端供电。
可选地，在本发明实施例中，第一预设切换条件可以包括：当前供电电池的电压值小于或等于第一预设阈值，该第一预设阈值表示当前供电电池处于低电量状态。如果当前待充电电池的电压值也满足第一预设切换条件，则说明当前待充电电池也不适合供电，这时候，控制模块220还可以从当前既不是待充电电池，又不是供电电池的那些电池中选择供电电池，或者可以采用外部供电电源继续为终端供电，直至当前待充电电池的电量高于第一预设阈值的时候再切换成由当前待充电电池供电。
本发明实施例中的控制模块220，还设置为：当监测模块230监测到当前待充电电池的电压满足第二预设切换条件时，将满足第二预设切换条件的每个当前待充电电池切换为当前供电电池，并从当前未进行充电的N-M个电池中重新选择待充电电池。
可选地，在本发明实施例中，第二预设切换条件可以包括：当前待充电电池的电压值大于或等于第二预设阈值，该第二预设阈值表示当前待充电电池充电完成。虽然第二预设阈值表示充电完成，但是这并不意味着终端的电量为100％，因为第二预设阈值可以是由开发人员在设置开发终端设置的，也可以是由用户自定义设置的，例如开发人员或者用户人为地设置电池电量 大于96％就表征充电完成，虽然电池此时还可以继续充电，但是在本发明实施例中，当当前待充电电池的电量大于96％的时候就可以将其切换为当前供电电池，并从当前充电未完成的电池中重新选择待充电电池。在实际应用中，控制模块220选择的范围可以是当前供电电池，也可以是既不是当前待充电电池也不是当前供电电池的那些电池。
本发明实施例中提供的终端充电控制装置20可以部署在终端上，其中，选择模块210和控制模块220的功能可以通过计算机程序实现，将对应的计算机程序存储在终端的内存当中，并由终端的控制器从内存当中读取对应的程序代码来实现对应的功能，而监测模块230的功能则可以由硬件电路来实现，这里给出一种示例：设置比较电路作为监测模块230，比较电路的参考电压可以是第一预设阈值或者第二预设阈值，当一个比较电路需要监测供电电池的电压时，可以选择第一预设阈值设置参考电压，而如果要监测当前待充电电池的电压，则可以将对应比较电路的参考电压设置为第二预设阈值。平常的时候，比较器输出低电平，当其监测到电压值满足第一预设切换条件或者是第二预设切换条件时，其可以输出高电平给控制器，控制器根据接收到的比较电路的输出确定对应的处理策略。
本发明实施例提供的终端充电控制装置，通过对同一时刻的当前待充电电池与当前供电电池进行区分，保证对一块电池进行充电的时候该电池不需要同时为终端供电，因此，有效地避免了对当前待充电电池进行充电的噪声或者杂波通过供电引入终端***的问题，提高了终端***的可靠性与稳定性，保证了终端的安全，提高了用户体验。
另外，本发明实施例提供的终端充电控制装置，通过对当前供电电池的电压进行监测，如果发现当前供电电池的电压值满足第一预设切换条件时，可以重新选择当前供电电池，在当前供电电池电量不足，无法继续供电的时候，能够通过切换其他电池作为供电电池保证终端***继续运行。另一方面，本发明实施例提供的终端充电控制装置，还通过对当前待充电电池的电压值进行监测，在发现当前待充电电池充电完成之后立即切换到位其他电池进行充电，避免浪费充电时间，提高充电效率。
本发明实施例还提供一种终端，如图5所示，为本发明实施例提供的一种终端的结构示意图。本发明实施例提供的终端上设置有多块配置有充电功能的电池40，电池40具有与外部供电电源连接的充电支路41和与***供电接口连接从而实现供电的供电支路42。在充电支路41与供电支路42上分别设置有两个第一开关单元411和421。第一开关单元411和第一开关单元421分别用于控制充电支路41和供电支路42的通断。
可选地，图6为本发明实施例提供的另一种终端的结构示意图。在图5所示终端的结构基础上，本发明实施例提供的终端除了包括多个电池40以外，还包括：控制器51和***供电接口522。
其中，***供电接口522与供电电源连接，设置为：为控制器51、显示屏(未示出)、音频输入输出单元(未示出)或者通信单元(未示出)等供电。
可选地，图7为本发明实施例提供的又一种终端的结构示意图。为了便于终端对各个器件的供电进行宏观管理，终端可以设置为包括***供电接口522的电源管理单元52。电源管理单元52，设置为：在控制器51的控制下接收电能并且提供操作各元件和组件所需的适当的电力。
为了便于说明，在这里将各个电池40以40A、40B、40C……的方式进行编号，本领域技术人员应当明白的是，A、B、C等仅为了区分不同的电池，并不能代表电池本身的构成或者结构的区别。控制器51从电池40A、40B、40C……中选择当前满足充电条件的电池作为当前待充电电池，选择当前待充电电池的时候，控制器51可以根据充电条件进行，充电条件由终端开发人员或者是用户预先设置完成，例如：设置选择当前电量最低的M个电池为当前待充电电池，在实际应用中，M可以为大于0的整数。可选地，充电条件也可以是电量低于预设阈值的电池。在上述两种充电条件的情况下，选择机制是不同的，第一种是预先设置选择个数，则最终选择出的当前待充电电池的个数是一定的；而第二种是预先设置了成为当前待充电电池的条件，选择出来的当前待充电电池的个数不定。
可选地，在本发明实施例中，控制器51还会从N个电池40A、40B、40C……中选择出其中电压值大于第一预设阈值的电池作为当前供电电池， 第一预设阈值是能够为终端供电的最低电压，也就是说，第一预设阈值表示该当前供电电池处于低电量状态。假定控制器51选择出的当前供电电池的数目为K，则K为大于或等于0的整数。
在实际应用中，由于控制器51的工作离不开电源支持，因此在控制器51选择出当前供电电池之前就提供电源供终端***开始运行，为此，可以在终端内部设置一个临时电池，如可更换的纽扣电池等。临时电池平时不使用，仅在监测终端需要充电，到终端确定出供电电池的期间内为终端***供电。或者采用相关技术中的方式，让外部供电电源短暂的为终端***供电。可选地，在这种方式中，终端还包括一条外部供电支路，该外部供电支路用于连接***供电接口522与外部供电电源，外部供电支路上设置有对应的第二开关单元，第二开关单元设置为：控制该外部供电支路的通断。在默认状态下，第二开关单元处于闭合状态的，除非控制器52进行了断开控制。另外，本发明实施例描述的***处于运行状态并不是指开机状态，是指终端***控制某些进程的状态，但是此时呈现给用户的界面可能依然是关机状态。
可选地，在本发明实施例中，控制器51将第一预设阈值作为选择因素选择出来的当前供电电池的数目例如为K个，K为大于或等于0的整数；在选择K个电池作为当前的供电电池之前，本发明实施例中的控制器51，还设置为：控制外部供电电源与***供电接口连通为该终端供电。
在本发明实施例的一个应用场景中，当K大于0的时候，表征出当前可以直接由终端配置有充电功能的电池来为终端供电，保证***运行。这时控制器51可以控制选择出的当前供电电池的供电支路上开关单元闭合，再此之后断开第二开关单元。
在本发明实施例的另一个应用场景中，如果终端所有电池的电压值都低于第一预设阈值，则控制器51无法选择出当前供电电池为终端***供电，即K等于0，在这种情况下，在当前待充电电池充电电量超过第一预设阈值之前依旧可以采用外部供电电源，控制器51在此期间不会关断第二开关单元。
可选地，图8为本发明实施例提供的再一种终端的结构示意图。在本发明上述实施例的结构基础上，终端除了包括控制器51、多个电池(40A、40B、 40C……)、包括***供电接口522的电源管理单元52以外，还可以包括：电压监测单元53，该电压监测单元53监测对象包括当前供电电池与当前待充电电池，对于这两者的监测没有严格时序限制，在实际应用中，可以在选择出当前待充电电池与供电电池的时候，电压监测单元53就对当前待充电电池和当前供电电池的电压分别进行监测。
本发明实施例中的控制器51，还设置为：当电压监测单元53检测到当前供电电池的电压满足第一预设切换条件时，断开满足第一预设条件的每个当前供电电池与***供电接口之间的电连接，并从当前待充电电池中重新选择供电电池为终端供电；在实际应用中，控制器51通过控制对应的第一开关单元断开当前供电电池的供电支路，并从当前待充电电池中重新选择供电电池，导通重新选择出的供电电池的供电支路，并断开重新选择的供电电池的充电支路；该第一预设阈值表示所述当前供电电池处于低电量状态。
当前供电电池的电压满足第一预设切换条件，表示当前供电电池不再适合为终端供电，对于当前供电电池不再适合供电的情况，控制器51还可以从当前待充电电池中重新选择供电电池为终端供电。
可选地，在本发明实施例中，第一预设切换条件可以包括：当前供电电池的电压值小于或等于第一预设阈值，该第一预设阈值表示当前供电电池处于低电量状态。如果当前待充电电池的电压值也满足第一预设切换条件，则说明当前待充电电池也不适合供电，这时候，控制器51还可以从当前既不是待充电电池，又不是供电电池的那些电池中选择供电电池，或者可以采用外部供电电源继续为终端供电，直至当前待充电电池的电量高于第一预设阈值的时候再切换成由当前待充电电池供电。
本发明实施例中的控制器51，还设置为：当电压监测单元53监测到当前待充电电池的电压满足第二预设切换条件时，将满足第二预设切换条件的每个当前待充电电池切换为当前供电电池，并从当前未进行充电的N-M个电池中重新选择待充电电池；在实际应用中，控制器51通过控制对应的第一开关单元断开当前待充电电池的充电支路，导通当前待充电电池的供电支路；并从当前未进行充电的N-M个电池中重新选择待充电电池，并控制导通重新选择出的待充电电池的充电支路，断开重新选择的待充电电池的供电 支路；该第二预设阈值表示所述当前待充电电池充电完成。
可选地，在本发明实施例中，第二预设切换条件可以包括：当前待充电电池的电压值大于或等于第二预设阈值，该第二预设阈值表示当前待充电电池充电完成。虽然第二预设阈值表示充电完成，但是这并不意味着终端的电量为100％，因为第二预设阈值可以是由开发人员在设置开发终端设置的，也可以是由用户自定义设置的，例如开发人员或者用户人为地设置电池电量大于96％就表征充电完成，虽然电池此时还可以继续充电，但是在本发明实施例中，当当前待充电电池的电量大于96％的时候就可以将其切换为当前供电电池，并从当前充电未完成的电池中重新选择待充电电池。在实际应用中，控制器51选择的范围可以是当前供电电池，也可以是既不是当前待充电电池也不是当前供电电池的那些电池。
可选地，本发明实施例提供还一种电压监测单元53的实现方式：设置比较电路作为电压监测单元53，比较电路的参考电压可以是第一预设阈值或者第二预设阈值，当一个比较电路需要监测供电电池的电压时，可以选择第一预设阈值设置参考电压，而如果要监测当前待充电电池的电压，则可以将对应比较电路的参考电压设置为第二预设阈值。平常的时候，比较器输出低电平，当其监测到电池的电压值满足第一预设切换条件或者是第二预设切换条件时，其可以输出高电平给控制器51，控制器51根据接收到的比较电路的输出确定对应的处理策略。
本发明实施例提供的终端，通过设置多个电池，在需要充电的时候，由控制器选择当前待充电电池和供电电池，实现了电池充电与供电两个过程的分离，避免了通过供电将充电的噪声或者杂波引入***的问题，保证了***的稳定性与可靠性，另外，本发明实施例中终端中还设置了电压监测单元对当前待充电电池与供电电池的电压进行实时监测，当发现供电电池电量不足或者是待充电电池充电完成时可以进行切换，达到了保证***对充电过程完整控制以及保证不浪费充电时间的效果。
在本发明上述实施例提供的终端的结构基础上，本发明实施例以终端为智能手机为例，对智能手机中设置的两块电池的充电情况进行说明，请参考 图9和图10，图9为本实施例提供的智能手机的充电控制电路的结构示意图，图10为图9所示智能手机的一种充电过程的流程图。
本发明实施例中的电源适配器70不属于智能手机，其仅仅是智能手机充电时所用到的一个配件而已。对于电源适配器70的型号，本发明实施例并没有特别的限定，可以采用相关技术中通用的电源适配器即可，当然本发明实施例并不排出其他类型的电源适配器，而且随着技术的发展，未来通用电源适配器可能也与相关技术中市面上生产销售的各种电源适配器不同，但本领域技术人员应当明白的是，这些电源适配器也应当涵盖在本实施例的范围内。
本发明实施例中的充电芯片81可以采用带充电路径管理的集成电路(Integrated circuit，简称为：IC)，其包括一个直接可以和电源管理单元86中***供电接口861连接的供电输出(OUT)接口811和一个用于和电池充电支路相连的充电输出(OUT)接口812，带充电路径管理的充电芯片81可以保证智能手机电池处于馈电状态时，其与外部供电电源连接之后，智能手机***可以启动。
电池组82包括两块电池，分别是第一电池821和第二电池822，这里的第一电池821与第二电池822分别包括电池充电接口与电池供电接口。
控制单元83是本发明实施例中智能手机的核心，控制单元83包括第一开关SW1、第二开关SW2、第三开关SW3、第四开关SW4、第五开关SW5以及微控制器MCU(Microcontroller Unit)831。每个开关都受到微控制器831的控制，其中由于智能手机在关机状态下进行充电时，微控制器831的运行需要外部供电电源的支持，因此第五开关SW5默认处于闭合状态。控制单元83上每个开关还可以通过智能手机***上的通用输入/输出(General Purpose Input Output，简称为：GPIO)控制。
电压监测电路84，设置为：监测第一电池821和第二电池822的电压，并肩监测结果返回给微控制器831。
另外，智能手机还包括防倒灌电路85，防倒灌电路85，设置为：防止两块电池之间的电流倒灌，导致***异常。这里的防倒灌电路可以使用二极管、MOS管或者防电流倒灌芯片等实现。
由于第五开关SW5是默认闭合的，因此，当智能手机中充电芯片81通过电源适配器70与外部供电电源连接之后，外部电源能够通过充电芯片81的供电输出接口811输出到智能手机电源管理单元86中的***供电接口，为智能手机的***供电，保证微控制器831启动。
下面结合图10所示的流程图对智能手机的充电过程进行说明：
S901、微控制器831获取电压监测电路85的监测结果。
电压监测电路84可以实时将监测结果传输给微控制器831，以供微控制器831能够针对智能手机充电过程中的各种情况及时做出对应的控制动作。
S902、微控制器831根据监测结果判断第一电池821或第二电池822的电压值是否大于开机电压。
S902中微控制器831的判断过程实质上是确定出两个电池中是否存在电压值还足够为智能手机供电的电压值；如果判断结果为是，则执行S903，如果判断结果为否，则继续采用外部供电电源为智能手机供电。
S903、微控制器831判断第一电池821的电压值是否高于第二电池822的电压值。
该步骤的判断将决定到底由第一电池供电还是由第二电池供电；如果判断结果为是，则执行S904，如果判断结果为否，则执行S905。
S904、微控制器831控制闭合第三开关SW3和第二开关SW2，然后断开第一开关SW1、第四开关SW4和第五开关SW5。
S905、微控制器831控制闭合第一开关SW1、第四开关SW4，然后断开第三开关SW3和第二开关SW2和第五开关SW5。
举例来说，若假定第一电池821的电压低于第二电池822的电压，则第一电池821会作为当前待充电电池，然后由第二电池822作为当前供电电池。图11为图9所示智能手机的另一种充电过程的流程图，下面结合图11继续对充电过程中的监测过程进行说明。
S1001、微控制器判断当前供电电池的电压值是否小于开机电压。
微控制器的判断依据来源于电压监测电路的实时监测结果。如果判断结果为是，则执行S1002，如果判断结果为否，则执行S1003。
S1002、微控制器判断当前待充电电池的电压值是否小于开机电压。
如果判断结果为是，则说明当前待充电电池的不足以为智能手机供电，执行S1004，如果判断结果为否，则执行S1005。
S1003、微控制器判断当前待充电电池是否充电完成。
如果判断结果为是，则执行S1006。
S1004、微控制器控制闭合第五开关，断开当前供电电池的供电支路；随后继续执行S1002。
S1005、微控制器控制导通当前待充电电池的供电支路，断开其充电支路，并断开供电电池的供电支路，导通其充电支路，随后继续执行S1001。
S1006、微控制器判断当前供电电池是否充电完成。
如果判断结果为是，则执行S1007，如果判断结果为否，则执行S1005。
S1007、停止充电。
如果智能手机在不插电源的情况下开机，此时***默认SW3和SW4是导通的，这样做是为了保证***在不插充电器的任何状态下两个电池的放电都为通路，保证***可以正常启动。***在启动过程中微控制器831需要判断第一电池821和822是否都小于开机电压，如果判断结果为是，则停止启动，并通过显示单元或者告警单元并提示用户充电。智能手机的***在初始状态下默认SW1和SW5导通，因此如果第一电池或第二电池能够供电，则需要断开SW5。***运行过程中，两个电池可以同时供电，因为有倒灌电路85的存在，两节电池之间并不会存在干扰，电压高的输出电流大，电压低的输出电流小。
另外，在***运行过程中，需要每隔设定时间检测或者实时监测第一电池821和第二电池822的电压，如果都到达关机电压门限，则控制***关机。如果没有到达关机电压门限，***正常工作。
本发明实施例提供的智能手机，通过设置两个电池，在需要充电的时候，由微控制器选择当前待充电电池和供电电池，实现了电池充电与供电两个过程的分离，避免了通过供电将充电的噪声或者杂波引入***的问题，保证了***的稳定性与可靠性。
