In some embodiments, electrochromic membrane 200 includes a first electrochromic membrane 210 and a second electrochromic membrane 220. The first electrochromic film 210 is used for indicating the power of the battery assembly 110, and can display different colors or color changes according to the power of the battery assembly 110. The second electrochromic film 220 is used for indicating the operating state of the battery assembly 110, and can display different colors or color variation trends according to the operating state of the battery assembly 110.

When the battery assembly 110 is in a charging state, the color of the second electrochromic film 220 changes in a unidirectional manner from light to dark, for example, the color changes from transparent colorless to gray black to black in a unidirectional manner gradually, so as to indicate that the electric quantity of the battery assembly is gradually increased; when the battery assembly 110 is in a discharging state, the color of the second electrochromic film 220 changes in a unidirectional manner from dark to light, for example, the color changes gradually from black, gray, transparent, colorless, to indicate that the electric quantity of the battery assembly is gradually decreasing; second electrochromic membrane 220 maintains a fixed color when battery assembly 110 is not operating.

In addition, the operating state of the battery assembly 110 can also be indicated by displaying different colors through the electrochromic film. In some examples, an electrochromic membrane in a first color, e.g., colored (dark), indicates that the battery assembly 110 is in a charged state; when the electrochromic film is in a second color, such as decolored (light), it indicates that the battery assembly 110 is in a discharged state; when the electrochromic film is a third color, e.g., colorless (transparent), it indicates that the battery assembly 110 is in an inoperative state.
