技术领域
本发明实施例涉及电子领域，尤其涉及一种电子设备及其充电方法。
背景技术
随着电子产品功能的多元化，及其外观的小型化，穿戴式电子产品越来越受到消费者青睐。目前，市场上的穿戴式电子设备主要有手环和手表。为获得好的用户体验，穿戴式电子设备通常都具有轻、薄的特点，电池容量往往被限制的非常小，用户在使用过程中需要对产品进行频繁充电。
现有技术中的充电方式包括两种，第一种充电方式为有线式充电。例如通过通用串行总线(英文全称：Universal Serial Bus，英文简称：USB)连接进行充电。第二种充电方式为无线式充电。例如，电磁感应式充电或者磁场共振充电。这种充电方式下，充电器内需要设有产生磁场的线圈，以及相关控制电路，而电子产品内需要设有电力转换装置以及高频滤波电路等，导致产品设计更加复杂，也增加了产品成本。
最重要的一点，穿戴式电子设备是一种移动设备，而以上两种充电方式要求电子设备连接充电器或者置于充电器附近才可以进行充电，不能在移动过程中进行充电，严重影响了用户的使用体验。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的实施例提供一种电子设备及其充电方法，电子设备包括光伏发电单元，用于通过所包含的光伏材料产生的电能为电子设备的电池充电，从而实现在移动过程中为电子设备充电的目的。电子设备可以是各种移动设备，包括各种穿戴式电子设备，例如便携式的紧急照明灯、智能手环手表等。
传统的电子设备与充电器有线连接的充电方式，以及电子设备靠近充电器通过无线连接进行充电的方式，由于充电过程中电子设备可以活动的范围十分有限，在本发明的实施例中，将以上传统的充电方式称为固定式充电方式，将通过光伏材料为电子设备进行充电的方式称为移动式充电方式。根据电子设备的应用场景，电子设备可以仅以移动式充电方式进行充电，也可以与固定式充电方式相结合，作为电子设备主要的或者辅助性充电方式。
实施例一
本发明的实施例一提供一种电子设备的充电方法，通过对电子设备满足一定条件的运动状态在一定时间内所出现的次数进行计数，并根据计数结果设定对光伏材料的发电参数进行调整的时间间隔，参照图1所示，具体包括以下步骤：
101、检测电子设备的运动次数。
其中，运动次数为电子设备满足预设条件的运动状态在第一预设时长内累计出现的次数。
可选的，电子设备可以周期性检测运动次数，且第一预设时长的长度小于检测周期。例如，检测周期可以设为1分钟，第一预设时长可以设为25秒。则在每个检测周期的0时间点到第25秒的时间段内，电子设备确定当前检测周期的运动次数。
或者，可选的，在电子设备没有对运动次数进行检测时，当满足预设条件的运动状态第一次出现时，电子设备触发对运动次数的检测，即开始对运动次数进行计数。在第一预设时长之后，电子设备将运动次数归零，并停止计数。直到满足预设条件的运动状态再次出现时，则再次触发对运动次数的检测。这种检测方式可以应用于电子设备频繁运动的情况，从而尽可能实时获取电子设备的运动次数，利于及时地调整对光伏材料的发电参数进行调整的时间间隔。
具体的，电子设备可以通过运动传感器对电子设备的运动次数进行检测。以运动传感器具体为重力传感器的应用场景为例，第一预设时长可以设为25秒，满足预设条件的运动状态可以为重力加速度大于设定值的运动状态。例如，设定值具体为1个重力加速度时，电子设备对25秒内运动加速度大于1个重力加速度的运动状态进行累计，以累计结果作为运动次数。
当然，还可以采用其它类型的运动传感器对电子设备的运动次数进行检测，例如陀螺仪、磁力计等。以陀螺仪作为运动传感器的情况为例，满足预设条件的运动状态可以为电子设备旋转角速度大于设定值的运动状态。预设条件可以根据运动传感器的具体种类进行设定。
102、根据运动次数设定时间周期。
其中，时间周期为对光伏材料的开路电压进行采样的时间周期。
电子设备包括光伏发电单元，用于通过所包含的光伏材料产生的电能为电子设备的电池充电。光伏材料的输出功率为输出电压和输出电流的乘积，在一定光照强度下，通过调整输出电压，可以对光伏材料的输出功率进行调整。根 据光伏材料的伏安特性，当输出电压在一定区间内不断增大时，输出功率增大，当输出电压超出该区间时，输出功率骤降，因此在光照强度一定的情况下，光伏材料的输出功率有最大值。
本发明的实施例以光伏材料的发电参数为光伏材料的工作点的情况为例进行说明。光伏材料的工作点指光伏材料的输出电流和输出电压，调整光伏材料的工作点，即根据当前的光照强度设定光伏材料的输出电流和输出电压，以使光伏材料的输出功率尽可能接近最大值。通常情况下，在光伏材料正常工作时，输出电流保持稳定，因此调整光伏材料的工作点，主要是指设定输出电压。需要说明的是，设定的输出电压，其具体取值可以与重设前的输出电压相同，这取决于光伏材料所收到的光照强度的是否变化，或者变化的幅度。当光照强度变化幅度较小时，设定的输出电压通常与设定之前的值相等或者接近。
为便于描述，本发明的实施例中将输出功率最大时光伏材料的工作点称为最佳工作点，即最佳工作点为工作点的理想值。由于电子设备移动性的特点，电子设备所处的环境不断变化，会使得光伏材料的工作点偏离最佳工作点，因此需要经常对光伏材料的工作点进行调整，以使得工作点尽可能接近最佳工作点。
对光伏材料的工作点进行调整，可以提高光伏材料的输出功率，然而，在对光伏材料的工作点进行调整的过程中，需要采样光伏材料的开路电压，采样过程会降低光伏材料的输出功率，因此频繁地调整工作点并不利于提高光伏材料的输出功率。
本发明的实施例中，根据运动次数设定时间周期，目的在于根据运动次数对时间周期进行调整，以使得光伏材料的工作点尽可能长时间地保持在接近最佳工作点的水平，并尽可能减少因为调整工作点而造成输出功率下降的情况。
可选的，设定时间周期的具体方式可以为，当电子设备的运动次数属于预设次数区间时，将时间周期设定为第一时间周期，当运动次数不属于预设次数区间时，将时间周期设定为第二时间周期。其中，第二时间周期大于第一时间周期。
例如，第一预设时长为25秒，预设次数区间为6到8的闭区间，第一时 间周期为15秒，第二时间周期为30秒。如果电子设备在25秒内的运动次数属于6到8的闭区间时，则将时间周期设定为15秒。当电子设备在25秒内的运动次数小于6次时，说明电子设备没有频繁运动，因此其所处的环境并没有太大变化，环境光照强度没有改变或者改变较小，因此时间周期可以设得较长，具体为30秒。当电子设备在25秒内的运动次数大于8次时，说明电子设备频繁运动，此时即使调整工作点，由于电子设备频繁运动，工作点会很快偏移最佳工作点，为免因为频繁调整工作点而造成输出功率下降，时间周期可以设得较长，具体为30秒。
当然，可以将运动次数的取值划分成更多区间，并针对不同区间设定不同的时间周期，此处不再赘述。
103、按照时间周期对光伏材料的开路电压进行采样，并根据开路电压设定光伏材料的发电参数。
调整工作点的过程具体包括，对光伏材料的开路电压进行采样，根据开路电压设定光伏材料的输出电压。按照步骤102中所设定的时间周期，对光伏材料的开路电压进行采样。例如，时间周期设为15秒，则每隔15秒对光伏材料的开路电压采样一次。通常，输出电压为开路电压与预设系数之积，其中预设系数在0到1之间，例如预设系数设为0.8。在对光伏材料的开路电压进行采样时，光伏材料不能实现光电转换，因此根据电子设备的运动次数的不同，设定不同的时间周期，并按照设定的时间周期对光伏材料的发电参数进行调整，避免在不必要的情况下进行开路电压采样，影响光伏材料的输出功率。
当然，可以循环执行步骤101-步骤103，根据运动次数对时间周期进行动态调整，按照更新后的时间周期调整工作点。通过对时间周期进行动态调整，可以按照电子设备的运动次数进行工作点调整，以使得工作点尽可能长时间保持在接近最佳工作点的水平，并避免对工作点进行不必要的调整，造成的输出功率下降的情况。
104、根据电子设备的充电接口与充电设备的连接状态切换充电方式。
电子设备可以仅以移动式充电方式进行充电，也可以与固定式充电方式相结合，作为电子设备主要的或者辅助的充电方式。其中，移动式充电方式是指 通过光伏发电单元对电子设备进行充电。固定式充电方式是指通过充电设备对电子设备进行充电。
在一种具体的应用场景中，电子设备包括充电电路，用于为电子设备的电池充电。充电电路包括切换开关，在同一时间点切换开关只与光伏发电单元和充电接口其中之一导通，其中充电接口用于连接充电设备(充电器)，从而通过充电设备对电子设备充电。
当确定电子设备的充电接口与充电设备断开时，将切换开关与光伏发电单元导通，此时充电接口与电子设备的充电电路断开，光伏发电单元与电子设备的充电电路导通，在一定光照条件下，通过光伏发电单元对电子设备进行充电。
当确定电子设备的充电接口与充电设备连接时，将切换开关与充电接口导通，此时光伏发电单元与电子设备的充电电路断开，充电接口与电子设备的充电电路导通，从而通过充电设备对电子设备进行充电。
以智能手环为例，智能手环包括光伏材料，用于通过移动式充电方式进行充电，另外，电子设备还可以通过充电接口连接充电设备进行充电。其中充电接口可以是USB接口，充电设备包括充电器或者其它支持USB输出的设备，如个人电脑等。那么当智能手环的USB接口未连接充电设备时，通过移动式充电方式，执行步骤101-103所描述的步骤，利用光伏材料对智能手环进行充电。当智能手环的USB接口与充电设备连接时，从移动式充电方式切换至固定式充电方式，利用充电设备提供的电能对智能手环进行充电。当智能手环的USB接口与充电设备的连接断开时，在切换回移动式充电方式。
在电子设备支持移动式充电方式和固定式充电方式的应用场景中，通过光伏发电单元进行充电，可以减少通过固定式充电方式进行充电的次数，改善用户的使用体验。
本发明的实施例所提供的电子设备的充电方法，通过检测电子设备的运动次数，根据运动次数设定时间周期，按照时间周期对光伏材料的开路电压进行采样，并根据开路电压设定光伏材料的发电参数，以使得工作点尽可能长时间保持在接近最佳工作点的水平，并避免对工作点进行不必要的调整，造成的输出功率下降的情况。

控制单元203，用于根据运动检测单元202检测得到的运动次数设定时间周期，时间周期为对光伏材料的开路电压进行采样的时间周期。
控制单元203，还用于控制光伏发电单元201按照时间周期对光伏材料的开路电压进行采样，并根据开路电压设定光伏材料的发电参数。
可选的，控制单元203，具体用于当运动次数属于预设次数区间时，将时间周期设定为第一时间周期。当运动次数不属于预设次数区间时，将时间周期设定为第二时间周期，第二时间周期大于第一时间周期。
可选的，电子设备还包括切换单元204，
切换单元204，用于当确定电子设备的充电接口205与充电设备断开时，通过光伏发电单元对电子设备进行充电。当确定电子设备的充电接口205与充电设备连接时，通过充电设备对电子设备进行充电。图2所示为光伏发电单元201通过切换单元204与电池206连接的情况。当电子设备20不包括切换单元204时，光伏发电单元201直接与电池206连接。

实施例二
结合本实施例一，本发明的实施例二提供一种电子设备的充电方法，参照 图4所示，包括以下步骤：
401、检测光伏材料所受到的光照强度。
电子设备包括光伏发电单元以及光敏传感器，其中光伏发电单元用于通过所包含的光伏材料产生的电能为电子设备的电池充电，光敏传感器用于检测光伏材料所受到的光照强度。
可选的，光敏传感器可以是环境光传感器(英文全称：Ambient Light Sensor，英文简称：ALS)、光敏电阻以及光敏二极管等。
以ALS为例，ALS检测光照强度时本身会消耗电能，通过对ALS检测光照强度的方式进行调整，可以减少ALS的耗电。
具体的，ALS检测光照强度的方式包括持续检测和周期性检测。当检测得到的光照强度大于第一预设阈值时，持续检测光伏材料所受到的光照强度。当检测得到的光照强度不大于第一预设阈值时，ALS停止持续检测，开始周期性检测光伏材料所受到的光照强度。
检测光伏材料所受到的光照强度，用于根据光照强度对光伏材料的发电参数进行调整。本发明的实施例以光伏材料的发电参数为光伏材料的工作点的情况为例，对第一预设阈值的取值进行说明。
ALS检测光照强度时本身会消耗电能，同时，对光伏材料的工作点进行调整可以提高光伏材料的输出功率。将工作点调整之后光伏材料输出功率提高的部分，与ALS持续检测光照强度时所消耗电能的差值，作为功率收益。当光照强度较小时，功率收益较小，甚至为负值。当光照强度较大时，功率收益为正。可选的，第一预设阈值的取值可以设为功率收益为0时所对应的光照强度。
402、当检测得到的光照强度在第二预设时长内始终大于第一预设阈值，且检测得到的光照强度在第二预设时长内的最大变化量超过第二预设阈值时，对光伏材料的开路电压进行采样，并根据开路电压设定光伏材料的发电参数。
当光照强度大于第一预设阈值时，可以得到正的功率收益。在功率收益为正的前提下，若光照强度变化量较小，则无需调整工作点，以避免因为调整工 作点而造成输出功率下降的情况，因此只需在光照强度变化量超过第二预设阈值时才对工作点进行调整。其中，光照强度的变化量是指在第二预设时长内的最大变化量。
结合步骤401，当光照强度大于第一预设阈值时，ALS持续检测光伏材料所受到的光照强度，如果光照强度在第二预设时长内始终大于第一预设阈值，且在第二预设时长内的最大变化量超过第二预设阈值时，则对光伏材料的工作点进行调整。例如，第一阈值具体为1000勒克斯，第二预设阈值为500勒克斯，第二预设时长为15秒。则在15秒内，如果光照强度保持在1000勒克斯以上，并且最大变化量超过500勒克斯，此时对光伏材料的工作点进行调整，即根据当前的光照强度设定光伏材料的输出电流和输出电压。
对光伏材料的工作点进行调整的过程中需要对光伏材料的开路电压进行采样，采样过程中光伏材料不能实现光电转换，根据实际的光照情况的变化确定是否对光伏材料的发电参数进行调整，避免在不必要的情况下进行开路电压采样，影响光伏材料的输出功率。
通过循环执行步骤401-步骤402，对光伏材料的工作点进行动态调整，以使得工作点尽可能长时间保持在接近最佳工作点的水平。同时，当光照强度小于第一预设阈值时则无需对工作点进行调整，避免了对工作点进行不必要的调整，造成输出功率下降的情况。
403、根据电子设备的充电接口与充电设备的连接状态切换充电方式。
电子设备可以仅以移动式充电方式进行充电，也可以与固定式充电方式相结合，作为电子设备主要的或者辅助的充电方式。其中，移动式充电方式是指通过光伏发电单元对电子设备进行充电。固定式充电方式是指通过充电设备对电子设备进行充电。
在一种具体的应用场景中，电子设备包括充电电路，用于为电子设备的电池充电。充电电路包括切换开关，在同一时间点切换开关只与光伏发电单元和充电接口其中之一导通，其中充电接口用于连接充电设备(充电器)，从而通过充电设备对电子设备充电。
当确定电子设备的充电接口与充电设备断开时，将切换开关与光伏发 电单元导通，此时充电接口与电子设备的充电电路断开，光伏发电单元与电子设备的充电电路导通，在适宜的光照条件下，通过光伏发电单元对电子设备进行充电。
当确定电子设备的充电接口与充电设备连接时，将切换开关与充电接口导通，此时光伏发电单元与电子设备的充电电路断开，充电接口与电子设备的充电电路导通，从而通过充电设备对电子设备进行充电。
在电子设备支持移动式充电方式和固定式充电方式的应用场景中，通过光伏发电单元进行充电，可以减少通过固定式充电方式进行充电的次数，改善用户的使用体验。
本发明的实施例所提供的电子设备的充电方法，通过检测光伏材料所受到的光照强度，当检测得到的光照强度在第二预设时长内始终大于第一预设阈值，且在第二预设时长内的最大变化量超过第二预设阈值时，对光伏材料的开路电压进行采样，并根据开路电压设定光伏材料的发电参数，以使得工作点尽可能长时间保持在接近最佳工作点的水平，并避免对工作点进行不必要的调整，造成的输出功率下降的情况。

可选的，控制单元503，具体用于当光敏检测单元502检测得到的光照强度大于第一预设阈值时，控制光敏检测单元502持续检测光伏材料所受到的光 照强度。当光敏检测单元502检测得到的光照强度不大于第一预设阈值时，控制光敏检测单元502周期性检测光伏材料所受到的光照强度。
