技术领域
本申请涉及电致变色技术领域，例如涉及一种电致变色器件的调控方法及电子设备。
背景技术
电致变色器件是一种能够响应于外界电位差的施加，而改变其自身的光学性能的装置，其光学性能的变化主要由电致变色器件内的电致变色材料的离子嵌入或脱出而导致。
相关技术中的电致变色器件通常是在着色态和去色态之间进行光学性能切换。例如，在应用时，可以将电致变色器件复合于窗户中，形成电致变色窗户。当有外界强光时，用户可以将窗户的光学状态切换至着色态，从而在一定程度上削弱光线强度，提高人体舒适度；当外界环境光强较弱时，用户可以将窗户的光学状态切换至去色态，以增加入射的光强比例，提高室内的亮度。
但是在相关技术中，针对电致变色器件透过率的切换过程，通常只有两至三挡可调，即包括着色态挡和去色态挡，或者包括着色态挡、去色态挡和中间态挡，相应的调节方式单一，一般均是通过使用对应的电压直接对电致变色器件进行电压施加以调节至对应的透过率。随着透过率变化程度的增加，透过率调节的速度较慢，从而不能适应不同场景下的应用需求，大大降低了用户的使用体验。

具体实施方式
下面结合附图和实施例对本申请进行说明。此处所描述的具体实施例仅仅用于解释本申请。为了便于描述，附图中仅示出了与本申请相关的部分。
在讨论示例性实施例之前应当提到的是，一些示例性实施例被描述成作为流程图描绘的处理或方法。虽然流程图将多个步骤描述成顺序的处理，但是其中的许多步骤可以被并行地、并发地或者同时实施。此外，多个步骤的顺序可以被重新安排。当其操作完成时所述处理可以被终止，但是还可以具有未包括在附图中的附加步骤。所述处理可以对应于方法、函数、规程、子例程、子程序等等。
本申请实施例提供的电致变色器件的调控方法，可以由电子设备中设置的处理器来执行。该电子设备可以是电致变色器件自身，也可以是集成了电致变色器件的设备，还可以是结构上独立于电致变色器件，设置为控制电致变色器件的设备。为了便于解释，以下实施例中以电子设备为电致变色器件自身为例 进行说明。以下实施例中的电子设备也可以以其他类型的电子设备来执行。
图1为本申请一实施例提供的一种电致变色器件的调控方法的流程图。本实施例可适用于根据用户需求对电致变色器件的透过率进行多级调控的情况，该方法可以由电致变色器件中设置的处理器来执行。如图1所示，包括如下步骤：
S11、接收电致变色器件的透过率调节信号，透过率调节信号中携带针对电致变色器件的透过率的目标挡位值。
可以将电致变色器件的透过率按照变化顺序设置为多个挡位，当电致变色器件处于一个挡位时，即可以保持对应的透过率。针对该多个挡位，可以根据电致变色器件的类型进行设置。每种电致变色器件均包括一个自身的稳定态，即电致变色器件上的开路电压(Open Circuit Voltage，OCV)为0伏时对应的状态，在稳定态的基础上透过率升高则进入去色态，透过率降低则进入着色态。当稳定态对应透过率最低的着色态或者透过率最高的去色态，即电致变色器件只具备着色态或者去色态中的一种时，该多个挡位可以设置为稳定态挡位和至少一个着色态挡位，或者为稳定态挡位和至少一个去色态挡位。当稳定态位于着色态和去色态的中间位置时，该多个挡位可以设置为至少一个着色态挡位、稳定态挡位和至少一个去色态挡位，例如，着色态挡位和去色态挡位均设置为多个，以提供更多可能的透过率变化，从而提高用户的使用体验。针对不同类型的电致变色器件，均可以适用本申请实施例所提供的电致变色器件的调控方法。
在电致变色器件的使用过程中，用户可以根据对电致变色器件透过率的需求通过一种操作来触发生成透过率调节信号。示例性的，如在电致变色器件的外部设置与多个挡位对应的按钮，当用户按下一个按钮时，即可产生一透过率调节信号，且该透过率调节信号中即携带了与该按钮对应的目标挡位值，此时电致变色器件的处理器即可接收该透过率调节信号。电致变色器件也可以自发的根据周围的环境生成透过率调节信号。示例性的，电致变色器件可以按照一定的周期采集环境亮度，并根据环境亮度对应所需的透过率自动的产生一透过率调节信号，其中也包括了与所需的透过率对应的目标挡位值，产生的透过率调节信号可以直接发送至处理器进行处理。关于透过率调节信号的产生方式，本实施例中不作限制，也不限于上述的示例。
S12、获取电致变色器件的当前挡位值。
当前挡位值可以根据电致变色器件上的当前开路电压来获知。在电致变色 器件的正常使用范围内，对应不同的开路电压，电致变色器件可以保持在不同的透过率，即开路电压与透过率之间存在一一对应关系，当检测到电致变色器件上的当前开路电压后，即可根据该对应关系查找到对应的当前透过率，从而根据对透过率设置的挡位确定对应的当前挡位值。
S13、根据目标挡位值、当前挡位值以及电致变色器件自身的稳定态挡位值确定目标调压方式，以根据目标调压方式对电致变色器件的透过率进行调节。
可以通过使用所需电压对电致变色器件进行施加来实现透过率的调节，则确定目标调压方式的过程可以包括确定用于施加的电压值以及施加电压的截止条件等等。其中，施加电压为正时表示对电致变色器件进行正向充电，施加电压为负时表示对电致变色器件进行反向放电，需要进行充电或是放电可以根据电致变色器件中所使用的电致变色材料的性质以及调节的方向来确定。在确定了电致变色器件的目标挡位值和当前挡位值之后，可以根据目标挡位值、当前挡位值和稳定态挡位值之间的关系对透过率调节的过程进行分类，并根据分类结果确定所需的目标调压方式。示例性的，针对上述电致变色器件只具备着色态或者去色态的情况，透过率调节的过程可以包括：目标挡位值与当前挡位值相同、目标挡位值与稳定态挡位值相同、目标挡位值与当前挡位值位于稳定态挡位值的同侧且目标挡位值更靠近稳定态挡位值以及目标挡位值与当前挡位值位于稳定态挡位值的同侧且目标挡位值更远离稳定态挡位值等，针对上述稳定态位于着色态和去色态的中间位置的情况时，透过率调节的过程还可以包括目标挡位值与当前挡位值位于稳定态挡位值的异侧等。
不同的透过率调节过程对调压方式的要求不尽相同，示例性的，当目标挡位值与当前挡位值的差距较小时，可以直接通过目标挡位值对应的目标施加电压值对电致变色器件进行电压施加，以避免过调节，使得终点调节准确，当目标挡位值与当前挡位值的差距较大时，可以通过相对目标挡位值更远离当前挡位值所对应的施加电压值对电致变色器件进行电压施加，以提高调节的效率。在调节的过程中，还可以实时监测电致变色器件的挡位变化，并及时调整用于充电的电压值，以达到更好的效果。同时，对应不同的透过率调节过程，可以采用相同或不同的截止条件，其中的截止条件可以包括：电致变色器件的电流小于预设电流、充电时长达到预设时长或充电电量达到预设电量中的一种或至少两种的组合。在确定了目标调压方式之后，即可根据目标调压方式将电致变色器件的透过率调节至与目标挡位值对应的透过率状态，从而实现用户的需求。
本申请实施例所提供的技术方案，首先接收电致变色器件的透过率调节信号，并从中获取针对电致变色器件的透过率的目标挡位值，并获取电致变色器件当前正处于的当前挡位值，再根据目标挡位值、当前挡位值以及电致变色器 件自身具有的稳定态挡位值确定所需的目标调压方式，即可根据目标调压方式将电致变色器件的透过率调节至所需的状态。通过对电致变色器件透过率的不同程度调节过程选取对应的不同调节方式，实现了对电致变色器件的多级调控，从而使得所采用的调节方式更加适合对应场景的应用需求，使得调控过程更加快速准确，大大提高了用户的使用体验。
图2为本申请另一实施例提供的一种电致变色器件的调控方法的流程图。本实施例的技术方案在上述技术方案的基础上进行说明，可选的，可以首先根据透过率的切换方向对透过率调节的过程进行分类，再根据分类结果进行目标调压方式的确定。在本实施例中，根据目标挡位值、当前挡位值以及电致变色器件自身的稳定态挡位值确定目标调压方式，包括：根据目标挡位值、当前挡位值以及稳定态挡位值确定电致变色器件的透过率的切换方向；若切换方向为异向，则确定目标调压方式为第一调压方式，第一调压方式包括：采用目标挡位值对应的目标施加电压值对电致变色器件进行电压施加，直至满足第一预设截止条件。相应的，如图2所示，可以包括如下步骤：
S21、接收电致变色器件的透过率调节信号，透过率调节信号中携带针对电致变色器件的透过率的目标挡位值。
S22、获取电致变色器件的当前挡位值。
S23、根据目标挡位值、当前挡位值以及稳定态挡位值确定电致变色器件的透过率的切换方向。
若目标挡位值与当前挡位值位于稳定态挡位值的同侧，则确定透过率的切换方向为同向，若目标挡位值与当前挡位值位于稳定态挡位值的异侧，则确定透过率的切换方向为异向。如上述实施例，若电致变色器件只具有着色态或者去色态中的一种时，则透过率只存在同向切换的情况，若电致变色器件的稳定态位于着色态和去色态的中间位置时，则透过率可以同向切换也可以异向切换。但不论电致变色器件的类型，均可以在调节过程中首先根据目标挡位值、当前挡位值和稳定态挡位值确定得到透过率的切换方向，以提高方法的通用性。
S24、若切换方向为异向，则确定目标调压方式为第一调压方式，第一调压方式包括：采用目标挡位值对应的目标施加电压值对电致变色器件进行电压施加，直至满足第一预设截止条件。
若透过率的切换方向为异向，则可以直接通过目标挡位值对应的目标施加电压值对电致变色器件进行电压施加，从而使得终点调节准确，不容易发生过调节。其中，第一预设截止条件可以是满足电致变色器件的电流小于第一预设 电流、充电时长达到第一预设时长或者充电电量达到第一预设电量中的一种或至少两种的组合。
可选的，在采用目标挡位值对应的目标施加电压值对电致变色器件进行电压施加，直至满足第一预设截止条件之前，第一调压方式还包括：确定目标挡位值与当前挡位值之间的第一差值；将第一差值与第一预设挡位差进行比较；若第一差值大于第一预设挡位差，则采用目标挡位值对应的最大施加电压值对电致变色器件进行电压施加，并实时监测第一差值，直至实时监测到的第一差值变化至小于或等于第一预设挡位差时，进入采用目标施加电压值对电致变色器件进行电压施加，直至满足第一预设截止条件的步骤。
若透过率的切换方向为异向，则可以首先判断目标挡位值与当前挡位值的差距是否较大，即将第一差值与第一预设挡位差进行比较。若第一差值小于或等于第一预设挡位差，则说明差距较小，此时采用目标施加电压值对电致变色器件进行电压施加，即可很快的将电致变色器件调节至与目标挡位值对应的透过率状态，而且终点调节准确，不容易发生过调节。若第一差值大于第一预设挡位差，则说明差距较大，此时若采用目标施加电压值对电致变色器件进行电压施加，则调节速度较慢，针对尺寸较大的电致变色器件，使得用户体验变差，因此在这种情况下，可以采用与目标挡位值对应的最大施加电压值对电致变色器件进行充电，以加快透过率调节的速度。其中，最大施加电压值为与目标挡位值同向的最远离稳定态挡位值的挡位所对应的施加电压值。同时，由于采用最大施加电压值进行充电很容易过调节，因此，可以在施加电压的过程中，实时监测第一差值的变化，当第一差值变化至小于或等于第一预设挡位差时，即可进入采用目标施加电压值进行充电，直至满足第一预设截止条件的步骤，从而在提高调节效率的基础上，也保证了调节的准确率。
示例性的，电致变色器件的透过率具有21个挡位，其中挡位11为稳定态挡位，挡位1-10为着色态挡位，挡位12-21为去色态挡位。若目标挡位值为19，对应的目标施加电压值为0.8伏，对应的最大施加电压值为1.0伏，当前挡位值为6，第一预设挡位差为5，则透过率的切换方向为异向，且第一差值为13大于第一预设挡位差5，首先采用最大施加电压值1.0伏对电致变色器件进行电压施加，并实时监测电致变色器件上的当前开路电压，从而确定对应的当前挡位值，以实时判断第一差值是否小于或等于第一预设挡位差5，当第一差值小于或等于第一预设挡位差5时，改用目标施加电压值0.8伏对电致变色器件进行电压施加，直至电致变色器件的电流小于第一预设电流则停止充电。
另一方面，若透过率的切换方向为同向，则可以采用任意可行的方式对电致变色器件的透过率进行调节，在本实施例中不作限制。当目标挡位值为稳定 态挡位值时，可以直接将电致变色器件短路，直至短路时长达到预设短路时长，稳定态挡位可以直接通过对电致变色器件的正负极短路来实现，使得调节过程更加快速简便。
本申请实施例所提供的技术方案，通过确定电致变色器件的透过率的切换方向，并在确定切换方向为异向时采用目标施加电压值对电致变色器件进行电压施加，在目标挡位值与当前挡位值的差距较大时，采用最大施加电压值对电致变色器件进行电压施加，并实时监测电致变色器件上的当前开路电压，在目标挡位值与当前挡位值的差距变化至较小时，继续采用目标施加电压值对电致变色器件进行电压施加，在保证了终点调节准确的基础上，还可以提高调节的效率，从而更快的实现用户的需求。
图3为本申请再一实施例提供的一种电致变色器件的调控方法的流程图。本实施例的技术方案在上述技术方案的基础上进行说明，可选的，在本实施例中，根据目标挡位值、当前挡位值以及电致变色器件自身的稳定态挡位值确定目标调压方式，包括：根据目标挡位值、当前挡位值以及稳定态挡位值确定电致变色器件的透过率的切换方向；若切换方向为同向，则分别确定目标挡位值与稳定态挡位值之间的第二差值以及当前挡位值与稳定态挡位值之间的第三差值，将第二差值与第三差值进行比较，并根据比较结果确定目标调压方式。相应的，如图3所示，可以包括如下步骤：
S31、接收电致变色器件的透过率调节信号，透过率调节信号中携带针对电致变色器件的透过率的目标挡位值。
S32、获取电致变色器件的当前挡位值。
S33、根据目标挡位值、当前挡位值以及稳定态挡位值确定电致变色器件的透过率的切换方向。
S34、若切换方向为同向，则分别确定目标挡位值与稳定态挡位值之间的第二差值以及当前挡位值与稳定态挡位值之间的第三差值，将第二差值与第三差值进行比较，并根据比较结果确定目标调压方式。
若透过率的切换方向为同向，则可以判断目标挡位值相比于当前挡位值是否更加靠近稳定态挡位值，即可以通过比较第二差值和第三差值来实现，再根据比较结果确定更适合的目标调压方式。示例性的，若目标挡位值更加靠近稳定态挡位值，则可以采用与目标施加电压值反向的任意电压值对电致变色器件进行电压施加，来提高调节的速度；若目标挡位值更加远离稳定态挡位值，则可以采用比目标施加电压值更大的任意电压值对电致变色器件进行电压施加， 来提高调节的速度等等。
将第二差值与第三差值进行比较，并根据比较结果确定目标调压方式，包括：若第二差值小于第三差值，则确定目标调压方式为第二调压方式，第二调压方式包括：将电致变色器件短路，直至电致变色器件的当前开路电压在目标挡位值对应的目标施加电压值与稳定态挡位值对应的稳定态电压值之间的范围内，并继续采用目标施加电压值对电致变色器件进行电压施加，直至满足第二预设截止条件。
若第二差值小于第三差值，则确定目标挡位值更加靠近稳定态挡位值，则此时可以通过将电致变色器件短路的方式快速方便的对透过率向靠近稳定态挡位值的方向进行调节。相比较而言，采用与目标施加电压值反向的电压值进行充电，更容易在短时间将透过率调节至异向的挡位中(即若目标挡位值对应着色态挡位，则更容易调节至去色态挡位)，从而增加了控制难度，也增加了对过调节的结果进行再调节所需的时间。相对的，通过短路的方式更容易控制，也降低了过调节的程度。但是由于短路的方式也可能存在一定程度的过调节，因此，在通过短路的方式使电致变色器件上的当前开路电压到达目标施加电压值之后，还可以继续采用目标施加电压值对电致变色器件进行回充，直至满足第二预设截止条件，从而在提高调节效率的基础上，也保证了调节的准确率。其中，第二预设截止条件可以是满足电致变色器件的电流小于第二预设电流、充电时长达到第二预设时长或者充电电量达到第二预设电量中的一种或至少两种的组合，并且可以与第一预设截止条件相同。
示例性的，电致变色器件的透过率具有21个挡位，其中挡位11为稳定态挡位，挡位1-10为着色态挡位，挡位12-21为去色态挡位。若目标挡位值为14，对应的目标充电电压值为0.3伏，当前挡位值为18，则第二差值为3，第三差值为7，确定目标挡位值更加靠近稳定态挡位值，首先对电致变色器件进行短路，并实时监测电致变色器件上的当前开路电压，以实时判断当前开路电压是否到达目标施加电压值，当到达时，改用0.3伏对电致变色器件进行电压施加，直至电致变色器件的电流小于第二预设电流则停止充电。
或者，将第二差值与第三差值进行比较，并根据比较结果确定目标调压方式，包括：若第二差值大于第三差值，则确定目标调压方式为第三调压方式，第三调压方式包括：采用目标挡位值对应的目标施加电压值对电致变色器件进行电压施加，直至满足第三预设截止条件。
若第二差值大于第三差值，则确定目标挡位值更加远离稳定态挡位值，则此时可以直接通过目标挡位值对应的目标施加电压值对电致变色器件进行电压施加，从而使得终点调节准确，不容易发生过调节。其中，第三预设截止条件 可以是满足电致变色器件的电流小于第三预设电流、充电时长达到第三预设时长或者充电电量达到第三预设电量中的一种或至少两种的组合，并且可以与第一预设截止条件或第二预设截止条件相同。
可选的，在采用目标挡位值对应的目标施加电压值对电致变色器件进行电压施加，直至满足第三预设截止条件之前，第三调压方式还包括：确定目标挡位值与当前挡位值之间的第四差值；将第四差值与第二预设挡位差进行比较；若第四差值大于第二预设挡位差，则采用目标挡位值对应的最大施加电压值对电致变色器件进行电压施加，并实时监测第四差值，直至实时监测到的第四差值变化至小于或等于第二预设挡位差时，进入采用目标施加电压值对电致变色器件进行电压施加，直至满足第三预设截止条件的步骤。
若确定目标挡位值更加远离稳定态挡位值，则可以首先判断目标挡位值和当前挡位值的差距是否较大，即将第四差值与第二预设挡位差进行比较，其中，第二预设挡位差可以与第一预设挡位差相同。若第四差值小于或等于第二预设挡位差，则说明差距较小，此时采用目标施加电压值对电致变色器件进行电压施加，即可很快的将电致变色器件调节至与目标挡位值对应的透过率状态，而且终点调节准确，不容易发生过调节。若第四差值大于第二预设挡位差，则说明差距较大，此时若采用目标施加电压值对电致变色器件进行电压施加，则充电速度较慢，针对尺寸较大的电致变色器件，使得用户体验变差，因此在这种情况下，可以采用与目标挡位值对应的最大施加电压值对电致变色器件进行电压施加，以加快透过率调节的速度。其中，最大施加电压值为与目标挡位值同向的最远离稳定态挡位值的挡位所对应的施加电压值。同时，由于采用最大施加电压值进行电压施加很容易过调节，因此，可以在施加电压的过程中，实时监测第四差值的变化，当第四差值变化至小于或等于第二预设挡位差时，即可进入采用目标施加电压值进行电压施加，直至满足第三预设截止条件的步骤，从而在提高调节效率的基础上，也保证了调节的准确率。
示例性，电致变色器件的透过率具有21个挡位，其中挡位11为稳定态挡位，挡位1-10为着色态挡位，挡位12-21为去色态挡位。若目标挡位值为4，对应的目标施加电压值为-0.7伏，对应的最大施加电压值为-1.0伏，当前挡位值为10，第二预设挡位差为5，则第二差值为7，第三差值为1，确定目标挡位值更加远离稳定态挡位值，且第四差值为7大于第二预设挡位差5，首先采用最大施加电压值-1.0伏对电致变色器件进行电压施加，并实时监测电致变色器件上的当前开路电压，从而确定对应的当前挡位值，以实时判断第四差值是否小于或等于第二预设挡位差为5，当第四差值小于或等于第二预设挡位差为5时，改用目标施加电压值-0.7伏对电致变色器件进行电压施加，直至电致变色器件的电流小于第三预设电流则停止充电。
另一方面，若透过率的切换方向为异向，则可以采用包括上述实施例中的调控方法等任意可行的方式对电致变色器件的透过率进行调节，在本实施例中不作限制。当目标挡位值为稳定态挡位值时，可以直接将电致变色器件短路，直至短路时长达到预设短路时长，稳定态挡位可以直接通过对电致变色器件的正负极短路来实现，使得调节过程更加快速简便。当第二差值与第三差值相同，即目标挡位值与当前挡位值相同时，则保持电致变色器件当前的透过率，不对其进行调节。
本申请实施例所提供的技术方案，通过确定电致变色器件的透过率的切换方向，并在确定切换方向为同向时，比较判断目标挡位值是否更加靠近稳定态挡位值，并根据比较结果确定相应的目标调压方式，在目标挡位值更加靠近稳定态挡位值时，通过短路的方式对透过率进行调节，并在当前开路电压到达目标施加电压值之后，继续采用目标施加电压值进行回充，在目标挡位值更加远离稳定态挡位值时，采用最大施加电压值对电致变色器件进行电压施加，并在目标挡位值与当前挡位值的差距变化至较小时，继续采用目标施加电压值进行电压施加，均实现了在保证了终点调节准确的基础上，还提高了调节的效率，从而更快的实现用户的需求。
图4为本申请又一实施例提供的一种电致变色器件的调控方法的流程图。本实施例的技术方案在上述技术方案的基础上进行说明，可选的，在完成了对电致变色器件的透过率调节过程之后，还可以采取措施对当前所处于的透过率进行保持，从而避免因透过率的变化降低用户的使用体验。本实施例中，在根据目标挡位值、当前挡位值以及电致变色器件自身的稳定态挡位值确定目标调压方式，以根据目标调压方式对电致变色器件的透过率进行调节之后，还包括：实时监测当前挡位值，并确定当前挡位值相对目标挡位值的偏移值，若偏移值大于第三预设挡位差，则采用目标挡位值对应的目标施加电压值对电致变色器件进行电压施加，直至满足第四预设截止条件。相应的，如图4所示，可以包括如下步骤：
S41、接收电致变色器件的透过率调节信号，透过率调节信号中携带针对电致变色器件的透过率的目标挡位值。
S42、获取电致变色器件的当前挡位值。
S43、根据目标挡位值、当前挡位值以及电致变色器件自身的稳定态挡位值确定目标调压方式，以根据目标调压方式对电致变色器件的透过率进行调节。
S44、实时监测当前挡位值，并确定当前挡位值相对目标挡位值的偏移值， 若偏移值大于第三预设挡位差，则采用目标挡位值对应的目标施加电压值对电致变色器件进行电压施加，直至满足第四预设截止条件。
在电致变色器件透过率调节的过程结束后，如果直接撤掉外部电源，则电致变色器件的透过率会慢慢朝向稳定态挡位变化。因此，当目标挡位值与稳定态挡位值不同时，则需要在透过率的调节过程结束后，进入透过率的保持过程。首先实时监控当前挡位值，可以通过实时监控电致变色器件上的当前开路电压来确定，然后实时确定当前挡位值相对目标挡位值的偏移值，若偏移值大于第三预设挡位值，则认定当前挡位值的偏移较大，需要对电致变色器件的透过率重新调节，此时即可直接采用目标挡位值对应的目标施加电压值对电致变色器件进行电压施加，直至满足第四预设截止条件。其中，第四预设截止条件可以是满足电致变色器件的电流小于第四预设电流、充电时长达到第四预设时长或者充电电量达到第四预设电量中的一种或至少两种的组合，第三预设挡位值可以根据挡位间透过率的变化程度进行设置，以保证透过率不会出现较大的变化。
本申请实施例所提供的技术方案，通过在完成了对电致变色器件的透过率调节过程之后，增加透过率的保持过程，保证了电致变色器件的透过率可以较为稳定的维持在用户所需的状态，提高了用户的使用体验。
图5为本申请还一实施例提供的一种电致变色器件的调控方法的流程图。本实施例的技术方案在上述技术方案的基础上进行说明，可选的，可以通过预存数据表单的方式便于电致变色器件更好的确定与目标挡位值对应所需提供的目标施加电压值。本实施例中，在根据目标挡位值、当前挡位值以及电致变色器件自身的稳定态挡位值确定目标调压方式之前，还包括：在电致变色器件内预存数据表单，数据表单包括预设挡位值与预设施加电压值之间的对应关系；相应的，根据目标挡位值、当前挡位值以及电致变色器件自身的稳定态挡位值确定目标调压方式，还包括：根据目标挡位值在数据表单中确定对应的目标施加电压值。在电致变色器件内预存数据表单，包括：在电致变色器件内预存多个数据表单，多个数据表单分别对应不同的环境温度和/或电致变色器件的老化程度；相应的，在根据目标挡位值、当前挡位值以及电致变色器件自身的稳定态挡位值确定目标调压方式之前，还包括：获取环境温度和/或电致变色器件的老化程度；根据获取的环境温度和/或电致变色器件的老化程度选择对应的目标数据表单。相应的，如图5所示，可以包括如下步骤：
S51、在电致变色器件内预存多个数据表单，多个数据表单分别对应不同的环境温度和/或电致变色器件的老化程度，数据表单包括预设挡位值与预设施加电压值之间的对应关系。
数据表单中可以包括预设挡位值与预设施加电压值之间的对应关系，从而在获取了目标挡位值之后，即可根据该对应关系确定与目标挡位值对应的目标施加电压值，然后即可根据目标调压方式以目标施加电压值为目标更直观的对电致变色器件的透过率进行调节。针对不同的环境温度和/或不同的电致变色器件的老化程度，将电致变色器件的透过率调节至目标挡位值所需的目标施加电压值可能不同，因此需要设置不同的数据表单以提供不同的对应关系，从而更好的确定多个挡位的透过率所需的目标施加电压值。通常随着温度升高，同一挡位对应的目标施加电压值将会减小，随着电致变色器件的老化程度增加，同一挡位对应的目标施加电压值将会增大。
S52、接收电致变色器件的透过率调节信号，透过率调节信号中携带针对电致变色器件的透过率的目标挡位值。
S53、获取电致变色器件的当前挡位值。
S54、获取环境温度和/或电致变色器件的老化程度。
环境温度可以通过配置的温度传感器等进行获取。针对电致变色器件的老化程度，可以对电致变色器件进行自检，在常温弱光的环境下记录初始峰值电流以及容量等参数，并在一段时间后再测一次，然后进行对比，则可以将参数值的变化比作为电致变色器件的老化程度，如果变化比小于预设值(可以是50％)，则可以选择对应的数据表单，如果变化比大于预设值，则可以认定电致变色器件已损坏，此时还可以将损坏情况向用户反馈，以提示更换玻璃。
S55、根据环境温度和/或电致变色器件的老化程度选择对应的目标数据表单。
还可以在电致变色器件中预存环境温度值和/或老化程度值与数据表单之间的对应关系，从而在获取了环境温度和/或电致变色器件的老化程度之后，即可选择对应的目标数据表单，以便于准确的确定所需的目标施加电压值。
S56、根据目标挡位值、当前挡位值以及电致变色器件自身的稳定态挡位值确定目标调压方式，并根据目标数据表单确定目标调压方式中所需的目标施加电压值，以根据目标调压方式对电致变色器件的透过率进行调节。
本申请实施例所提供的技术方案，通过在电致变色器件中预存数据表单，为电致变色器件确定与目标挡位值对应所需提供的目标施加电压值提供了方便，还可以根据环境温度和/或电致变色器件的老化程度预存不同的数据表单，以提供更加适合对应场景的目标施加电压，从而使得调控的过程更加准确，提高用户的使用体验。
