在充电领域，为了提高充电功率和提升充电效率，一般使用电荷泵作为快充的充电芯片。电荷泵可以把电压进行降低电压处理，将电压值降至原电压值的一半，而将电流提升至原电流的两倍，这样就可以达到更大功率的充电。进一步的，如果电池中两个电芯中的一个电芯的头部与另一个电芯的尾部连接，就可以在充电时进一步的提升充电电压，进而在充电电流一定的情况下得到更高的充电功率。
现有技术中的充电方式由于充电模式十分固定，导致充电过程易出现充电故障导致充电终端电池损坏，或者充电效率低下进而导致用户使用体验低下的问题。
针对目前由于充电模式十分固定，导致充电过程易出现充电故障导致充电终端电池损坏，或者充电效率低下进而导致用户使用体验低下的情况。本申请实施例提供了一种充电控制方法、控制器、充电终端及可读存储介质，充电终端通过获取充电器的输出能力参数和充电终端的电池输入能力参数，并将获取到的充电器的输出能力参数和充电终端的电池输入能力参数进行比较，得到充电时的第一充电功率，由于充电终端拥有多种充电芯片工作模式以及充电终端的电池同样拥有多种电池连接模式，通过将多种充电芯片工作模式和多种电池连接模式一对一地组合可以得出若干充电模式组合，并获取若干充电模式组合的第二充电功率，通 过将第一充电功率和第二充电功率进行比较进而对上述若干充电模式组合进行筛选，这样即可防止出现因为充电终端请求的输入功率大于充电器的输出功率导致充电效率低下，或者充电器的输出功率大于充电终端电池能够承受的最大输入功率进而对电池造成不必要的损耗。筛选出来的充电模式组合作为候选充电模式组合进行充电效率的计算得出不同候选充电模式组合的第一充电效率，并对不同的第一充电效率进行比较，进而筛选出充电效率最高的候选模式组合作为目标充电模式组合进行充电处理，这样即可在保证了充电的安全性的同时进行最高效的充电，大大提高了充电终端的整体充电效果进而提高用户的使用体验。
下面结合附图，对本申请实施例进行阐述。
如图1所示，图1是本申请一个实施例提供的用于执行充电控制方法的系统架构平台的示意图。

在图1所示的系统架构平台100中，处理器110可以用于调用存储器120中储存的控制程序，从而实现充电控制方法。
如图2所示，图2是本申请一个实施例提供的充电控制方法的流程图，本申请实施例的充电控制方法应用于充电终端，本充电控制方法包括但不限于有步骤S200、步骤S210、步骤S220、步骤S230和步骤S240。

步骤S230，对第一充电功率和第二充电功率进行比较，从多种充电模式组合中筛选出若干候选充电模式组合；
步骤S240，获取候选充电模式组合的第一充电效率，并根据第一充电效率从若干候选充电模式组合中确定目标充电模式组合，采用目标充电模式组合进行充电处理。
在本实施例中，充电终端在充电准备阶段会获取充电器的输出能力参数和充电终端的电池输入能力参数，将充电器的输出能力参数和充电终端的电池输入能力参数进行比较，得到第一充电功率，由于充电终端拥有多种充电芯片工作模式以及充电终端的电池同样拥有多种电池连接模式，通过将多种充电芯片工作模式和多种电池连接模式一对一地组合可以得出若干充电模式组合，并获取若干充电模式组合的第二充电功率，通过将第一充电功率和第二充 电功率进行比较进而对上述若干充电模式组合进行筛选，这样即可防止出现因为充电终端请求的输入功率大于充电器的输出功率导致充电效率低下，进而降低充电的速度和影响用户的使用体验，或者充电器的输出功率大于充电终端电池能够承受的最大输入功率进而对电池造成不必要的损耗。筛选出来的充电模式组合作为候选充电模式组合进行充电效率的计算得出不同候选充电模式组合的第一充电效率，并对不同的第一充电效率进行比较，进而筛选出充电效率最高的候选模式组合作为目标充电模式组合进行充电处理，这样即可在保证了充电的安全性的同时进行最高效的充电，大大提高了充电终端的整体充电效果进而提高用户的使用体验。
需要说明的是，上述充电效率的计算公式为一条关于充电电流、电池电压和电池温度的函数，即Effect＝F(fcc,voltage,temp)，其中Effect是充电效率，FCC是充电电流，voltage是电池电压，temp是电池温度。
如图3所示，图3是本申请另一个实施例提供的充电控制方法的流程图，本申请实施例的充电控制方法，包括但不限于有步骤S300和步骤S310。
步骤S300，获取充电器支持的充电协议和充电器的输出偏差；
步骤S310，当充电协议支持恒流充电模式并且输出偏差小于预设输出偏差，获取充电器的输出能力参数
在本实施例中，由于本申请提供的充电控制方法需要充电器的充电协议能够支持恒流充电模式，因此需要获取充电器支持的充电协议，并判断充电器支持的充电协议是否支持恒流充电模式。同样为确保充电过程中，对于充电功率的精确控制，充电器的输出误差不能大于预设的输出误差，因此，只有当充电器的充电协议支持恒流充电模式同时充电器的输出误差小于预设的输出误差，才会对充电器的输出能力参数进行获取。
需要说明的是，支持恒流充电模式的充电协议包括但不限于PD协议和PPS协议。
另外，需要说明的是，上述的输出偏差为充电终端请求的充电电流和充电器的输出电流之间的偏差。
如图4所示，图4是本申请另一个实施例提供的充电控制方法的流程图，本申请实施例的充电控制方法，包括但不限于有步骤S400、步骤S410和步骤S420。
步骤S400，获取充电器支持的充电协议，并根据充电协议查询得到充电器的输出能力参数；
步骤S410，获取充电终端的电池规格；
步骤S420，获取当前电池温度和当前系统温度，并根据当前电池温度和当前系统温度从电池规格中查询得到电池输入能力参数。
在本实施例中，通过获取充电器支持的充电协议并根据充电协议可以得到充电器的输出能力参数，通过获取充电终端的电池规格，当前电池温度和当前系统温度可以得到电池输入能力参数，直接通过获取充电协议以及电池规格、电池温度和系统温度即可得到充电器的输出能力参数和电池输入能力参数，减少了充电终端的数据处理压力，提升充电终端的整体处理速度，进而能够更加及时地作出相应的调整，提升充电终端的充电效果。
需要说明的是，上述电池规格包括电池温度、系统温度和电池输入能力参数的对应关系，基于获取到的当前电池温度和当前系统温度，并根据电池规格中的电池温度、系统温度和电池输入能力参数的对应关系查询得到当前情况下的电池输入能力参数。
如图5所示，图5是本申请另一个实施例提供的充电控制方法的流程图，本申请实施例的充电控制方法，包括但不限于有步骤S500和步骤S510。
步骤S500，当充电器的最大输出功率大于电池的最大输入功率。
步骤S510，将电池的最大输入功率作为第一充电功率。
在本实施例中，充电器的输出能力参数包括充电器的最大输出功率，电池输入能力参数包括电池的最大输入功率；对充电器的输出能力参数和电池输入能力参数进行比较，得到第一充电功率，即对充电器的最大输出功率和电池的最大输入功率进行比较，得到第一充电功率。当充电器的最大输出功率大于电池的最大输入功率，将电池的所述最大输入功率作为第一充电功率，这样即可确保输入电池的充电功率始终处于电池的承受范围之内，避免对电池造成不必要的损耗，提升电池的使用寿命进而提升用户使用体验。
如图6所示，图6是本申请另一个实施例提供的充电控制方法的流程图，本申请实施例的充电控制方法，包括但不限于有步骤S600和步骤S610。
步骤S600，当充电器的最大输出功率小于电池的最大输入功率。
步骤S610，将充电器的最大输出功率作为第一充电功率。
在本实施例中，充电器的输出能力参数包括充电器的最大输出功率，电池输入能力参数包括电池的最大输入功率；对充电器的输出能力参数和电池输入能力参数进行比较，得到第一充电功率，即对充电器的最大输出功率和电池的最大输入功率进行比较，得到第一充电功率。当充电器的最大输出功率小于电池的最大输入功率，将充电器的最大输出功率作为第一充电功率。这样即可确保能最大化地使用充电器，避免出现充电器一直以较低的输出功率进行充电进而降低充电的速度，进而影响用户的使用体验。
此外，在本申请的另一实施例中，充电器的输出能力参数包括充电器的最大输出功率，电池输入能力参数包括电池的最大输入功率；对充电器的输出能力参数和电池输入能力参数进行比较，得到第一充电功率，即对充电器的最大输出功率和电池的最大输入功率进行比较，得到第一充电功率。当充电器的最大输出功率等于电池的最大输入功率，将充电器的最大输出功率或电池的最大输入功率作为第一充电功率。这样即可确保能最大化地使用充电器，避免出现充电器一直以较低的输出功率进行充电进而降低充电的速度，进而影响用户的使用体验，同时，可确保输入电池的充电功率始终处于电池的承受范围之内，避免对电池造成不必要的损耗，提升电池的使用寿命进而提升用户使用体验。
如图7所示，图7是本申请另一个实施例提供的充电控制方法的流程图，本申请实施例的充电控制方法，包括但不限于有步骤S700、步骤S710、步骤S720和步骤S730。
步骤S700，获取第一充电功率和第二充电功率，并对第一充电功率和第二充电功率进行比较；
步骤S710，判断第二充电功率是否小于第一充电功率，若是，则执行步骤S720，否则执行步骤S730；
步骤S720，选为候选充电模式组合；
步骤S730，执行移除。
在本实施例中，第一充电功率的获取可参考如图5或图6示出的获取步骤，而第二充电功率的获取则是通过遍历充电终端的充电芯片工作模式和电池连接模式之后，将多种充电芯片工作模式和多种电池连接模式一对一组合得出多种充电模式组合，对上述多种充电模式组 合进行功率计算得出。对第一充电功率和第二充电功率进行比较并判断第二充电功率是否小于第一充电功率，若第二充电功率小于第一充电功率，则将对应的充电模式组合选为候选充电模式组合；若第二充电功率大于第一充电功率，则将对应的充电模式组合移除。
需要说明的是，在本实施例中第一充电功率代表着最大允许充电功率，当充电模式组合的第二充电功率大于第一充电功率，则说明该充电模式组合无法被完全利用，导致充电效果欠佳，影响用户使用体验，同时存在对电池造成不必要损耗的隐患。当充电模式组合的第二功率小于第一充电功率，则说明该充电模式组合能够被完全利用，进而提升充电效果和用户的使用体验。
如图8所示，图8是本申请另一个实施例提供的充电控制方法的流程图，本申请实施例的充电控制方法，包括但不限于有步骤S800、步骤S810和步骤S820。
步骤S800，获取候选充电模式组合的当前充电效率。
步骤S810，比较第一充电效率和当前充电效率，得到充电效率比较结果。
步骤S820，根据充电效率比较结果调整目标充电模式组合。
在本实施例中，因为在充电过程中，随着各项充电相关的参数发生变化，候选充电模式组合的充电效率同样也会随着发生变化，因而在充电过程中需要不断对候选充电模式组合进行计算，不断重新获取候选充电模式组合的当前充电效率，同时将当前充电效率和第一充电效率进行比较，得到充电效率比较结果，根据充电效率比较结果调整目标充电模式组合。这样才能确保目标充电模式组合的充电效率始终为最高的，提高充电终端的充电效果，提升用户使用体验。
需要说明的是，在本实施中，上述当前充电效率和第一充电效率的计算公均为一条关于充电电流、电池电压和电池温度的函数，即Effect＝F(fcc,voltage,temp)，其中Effect是充电效率，FCC是充电电流，voltage是电池电压，temp是电池温度。
如图9所示，图9是本申请另一个实施例提供的充电控制方法的流程图，本申请实施例的充电控制方法，包括但不限于有步骤S900和步骤S910。
步骤S900，第一充电效率与当前充电效率之间的差值小于预设效率调整差值。
步骤S910，保持选用第一充电效率对应的候选充电模式组合作为目标充电模式组合。
在本实施例中，因为在充电过程中，随着各项充电相关的参数发生变化，候选充电模式组合的充电效率同样也会随着发生变化，因而在充电过程中需要不断对候选充电模式组合进行计算，不断重新获取候选充电模式组合的当前充电效率，同时将当前充电效率和第一充电效率进行比较，得到充电效率比较结果，根据充电效率比较结果调整目标充电模式组合。
当第一充电效率与当前充电效率之间的差值小于预设效率调整差值，为避免乒乓效应的出现，所以保持选用第一充电效率对应的候选充电模式组合作为目标充电模式组合，这样才能确保目标充电模式组合的充电效率始终为最高的，提高充电终端的充电效果，提升用户使用体验。
需要说明的是，在本实施中，上述当前充电效率和第一充电效率的计算公均为一条关于充电电流、电池电压和电池温度的函数，即Effect＝F(fcc,voltage,temp)，其中Effect是充电效率，FCC是充电电流，voltage是电池电压，temp是电池温度。
如图10所示，图10是本申请另一个实施例提供的充电控制方法的流程图，本申请实施例的充电控制方法，包括但不限于有步骤S1000和步骤S1010。
步骤S1000，第一充电效率小于当前充电效率且与当前充电效率的差值大于预设效率调整差值。
步骤S1010，选用当前充电效率对应的候选充电模式组合作为目标充电模式组合。
在本实施例中，因为在充电过程中，随着各项充电相关的参数发生变化，候选充电模式组合的充电效率同样也会随着发生变化，因而在充电过程中需要不断对候选充电模式组合进行计算，不断重新获取候选充电模式组合的当前充电效率，同时将当前充电效率和第一充电效率进行比较，得到充电效率比较结果，根据充电效率比较结果调整目标充电模式组合。
当第一充电效率小于当前充电效率且与当前充电效率的差值大于预设效率调整差值，选用当前充电效率对应的候选充电模式组合作为目标充电模式组合，只有当第一充电效率小于当前充电效率才有调整选用当前充电效率对应的候选充电模式组合作为目标充电模式组合的必要性，并且为了防止出现乒乓效应，则需要第一充电效率与当前充电效率的差值大于预设阈值调整差值。这样才能确保目标充电模式组合的充电效率始终为最高的，提高充电终端的充电效果，提升用户使用体验。
需要说明的是，在本实施中，上述当前充电效率和第一充电效率的计算公均为一条关于充电电流、电池电压和电池温度的函数，即Effect＝F(fcc,voltage,temp)，其中Effect是充电效率，FCC是充电电流，voltage是电池电压，temp是电池温度。
如图11所示，图11是本申请另一个实施例提供的充电控制方法的流程图，本申请实施例的充电控制方法，包括但不限于有步骤S1100至步骤S1130。
步骤S1100，获取充电终端的新的电池输入能力参数；
步骤S1110，根据新的电池输入能力参数得到第三充电功率；
步骤S1120，比较第一充电功率和第三充电功率，得到充电功率比较结果；
步骤S1130，根据充电功率比较结果调整目标充电模式组合。
在本实施例中，因为在充电过程中电池电压达到一定程度之后允许的最大电流可能会下降，温度过高或者过低允许的最大电流也会需要限制，这时电池输入能力参数也会发生变化，因此需要获取充电终端新的电池输入能力参数，参考图4、图5和图6提供的实施例，根据新的电池输入能力参数得到第三充电功率，将第三充电功率和第一充电功率进行比较，得到充电功率比较结果，同时根据该比较结果调整目标充电模式组合。在充电过程中不断获取新的电池输入能力参数进而得到新的充电功率，再根据充电功率比较结果来调整目标充电模式组合，可以使得充电终端始终以合理安全的模式进行充电，提高充电终端的充电效果进而提升用户使用体验。
在本实施例中，第一充电功率大于新获取的第三充电功率，对应地需要对目标充电模式组合进行调整，包括：获取充电终端的每种充电模式组合的新的第二充电功率，其中，每种充电模式组合包括一种电池模式和一种输入模式；对第三充电功率和新的第二充电功率进行比较，从多种充电模式组合中筛选出若干候选充电模式组合；获取候选充电模式组合的第二充电效率，并根据第二充电效率从若干候选充电模式组合中确定目标充电模式组合，采用目标充电模式组合进行充电处理。通过将多种充电芯片工作模式和多种电池连接模式一对一地组合可以得出若干充电模式组合，并获取若干充电模式组合的第二充电功率，通过将第三充电功率和新的第二充电功率进行比较进而对上述若干充电模式组合进行筛选，这样即可防止出现因为充电终端请求的输入功率大于充电器的输出功率导致充电效率低下，进而降低充电 的速度和影响用户的使用体验，或者充电器的输出功率大于充电终端电池能够承受的最大输入功率进而对电池造成不必要的损耗。筛选出来的充电模式组合作为候选充电模式组合进行充电效率的计算得出不同候选充电模式组合的第二充电效率，并对不同的第二充电效率进行比较，进而筛选出充电效率最高的候选模式组合作为目标充电模式组合进行充电处理，这样即可在保证了充电的安全性的同时进行最高效的充电，大大提高了充电终端的整体充电效果进而提高用户的使用体验。
需要说明的是，上述充电效率的计算公式为一条关于充电电流、电池电压和电池温度的函数，即Effect＝F(fcc,voltage,temp)，其中Effect是充电效率，FCC是充电电流，voltage是电池电压，temp是电池温度。

如图13所示，图13是本申请一个实施例提供的充电控制方法的整体流程图，本申请实施例的充电控制方法，包括但不限于有步骤S1300至步骤S1370。

步骤S1360，切换目标充电模式组合
步骤S1370，判断充电功率是否需要调整，若是，则执行步骤S1330,否则循环执行步骤S1370。
在本实施例中，插入充电器，开始充电过程，之后检查充电器的能力，为了便于各种充电芯片工作模式都可以切换，需要充电器支持恒流充电模式才可以。检测恒流充电模式的方法是充电器要支持PD协议或PPS充电协议，并且请求的电流与实际输出的电流偏差在允许范围内。充电器满足条件则执行下一步，否则退出。之后获取最大允许充电功率，这个需要充电器的输出能力参数和电池输入能力参数共同决定。充电器的输出能力参数可以直接通过充电协议获取，电池输入能力参数需要根据电池规格以及当前的电池温度和系统温度共同决定，这里能够得到当前允许进入电池的最大电流值。之后根据充电终端的硬件设计方案，遍历充电终端支持的各种充电模式组合，得到满足当前最大允许充电功率需求的所有候选充电 模式组合。有些充电模式组合可能充电效率高，但是达不到这么高的充电功率，那么就会被移除。之后计算所有满足当前最大允许充电功率的候选充电模式组合的充电效率，充电效率根据公式Effect＝F(fcc,voltage,temp)计算得到，公式也可以简化为只与当前的充电电流相关。选择效率最高的候选充电模式组合作为目标充电模式组合进行充电处理。在充电过程中比较当前选用的目标充电模式组合与当前充电效率最高的候选充电模式组合是否相同，是否需要切换目标充电模式组合，如果不同则需要切换目标充电模式组合；如果相同则执行下一步。需要说明的是，为了避免乒乓效应，可以要求当前选用的目标充电模式组合与当前充电效率最高的候选充电模式组合之间的效率差异大于预设效率调整差值才执行切换目标充电模式组合。最后需要当前最大允许充电功率是否需要调整，电池根据电池规格，充电电压达到一定程度之后允许的最大电流可能会下降，温度过高或者过低允许的最大电流也会需要限制。如果当前最大允许充电功率没有变化，则继续循环当前步骤不断进行判断，否则查找新的最大允许充电功率情况下满足条件的候选充电模式组合并重新选择新的目标充电模式组合。
需要说明的是，上述充电效率的计算公式为一条关于充电电流、电池电压和电池温度的函数，即Effect＝F(fcc,voltage,temp)，其中Effect是充电效率，FCC是充电电流，voltage是电池电压，temp是电池温度，同样地，公式也可以简化为只与当前的充电电流相关。
