具体的，电致变色组件2的尺寸可以根据需求设置，例如，电致变色组 件2的尺寸可以与移动终端上的音量按键/电源按键的尺寸相同，还可以是采用电致变色材料制备成整个中框结构，同时作为电致变色组件。此外，电致变色组件2还可以设置成预定形状，例如，圆形、三角形、多边形，其他异型或特殊图形，例如，闪电形状，用于表征移动终端的充电状态。
可选地，为了便于用户看到电致变色组件2发出的光，可以将电致变色组件2嵌设于所述壳体的中框。例例如，所述壳体的中框设有开孔，所述电致变色组件2嵌设于所述中框的开孔内。
具体的，电致变色组件2可以是采用电致变色材料制成的发光片，电致变色组件2能够将电能直接转换为光能，即通过对电致变色组件2施加电压，使电场激发发光材料从而发光。
例例如，当移动终端未充电(例如，移动终端与充电底座3之间接触不良)时，无线充电模组1不能接收充电底座3发射的能量信号(例如，电信号)，从而电致变色组件2没有电场作用而不会发光，从而可以提示用户移动终端未处于充电状态；
当移动终端在充电时，无线充电模组1接收充电底座3发射的至少部分能量信号(例如，电信号)，并将所述电信号传输至电致变色组件2，这样电致变色组件2受该能量信号的电场作用而发光，可以提示用户移动终端处于充电状态。
特别的，所述电致变色组件2的发光颜色为至少一种颜色，例如，白色光，彩色光等。其中，彩色光可以通过蓝光与荧光剂转换实现。电致变色组件2的发光亮度范围为：30cd/m 2～200cd/m 2，电致变色组件2的消耗功率低，功率范围为：10mw/cm 2～20mw/cm 2。
具体的，电致变色组件2所发出光的颜色与无线充电模组1传输的能量信号的强度有关。经过无线充电模组1传输至电致变色组件2的能量信号的强度(例如，电信号的电压幅值)不同时，电致变色组件2可以显示不同的颜色。
例如，移动终端与充电底座的位置匹配达到预设条件，且移动终端可以最大功率充电时，电压幅值最高，电致变色组件2可以产生绿色的光，用于指示移动终端当前处于满足预设条件的充电状态；
当移动终端与充电底座的位置匹配未达到预设条件时，此时移动终端的充电功率小于该最大功率，则电致变色组件2可以产生黄色的光，以提醒用户调整位置，从而可以通过电致变色组件2发出不同颜色的光，提示用户移动终端当前的充电状态。
