Please refer to Figure 9, which discloses a flow chart of a control method of an electrochromic device in an embodiment of the present application. The control method may include the following steps:

Step S0901: after the color changing operation of the electrochromic device is completed using the preset control parameters, a first open circuit voltage of the electrochromic device is obtained.

It should be noted that the terms "first", "second", etc. herein and hereinafter are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of the features.

For an electrochromic device, a color-changing material is disposed inside the device, and the color-changing material can form a specific color, such as a colored (colored) state or a faded state, under a specific control voltage. In one embodiment, the faded state can be a transparent state.

In order to better control the electrochromic device, corresponding control parameters can be set according to the performance of the electrochromic device, so that the electrochromic device can be better controlled by utilizing this control parameter, so that the electrochromic device can be converted between the colored state and the faded state to complete the color changing operation (coloring operation and fading operation).

The corresponding control parameters may be referred to as preset control parameters. The preset control parameters may be stored in a corresponding electronic device such as a storage device (memory, memory card, etc.), and when the electronic device runs a specific program, the preset control parameters may be executed to perform a color changing operation such as a coloring operation and a fading operation on the electrochromic device.

For example, the coloring control parameters in the preset control parameters can be used to control the electrochromic device, and the coloring operation can be completed. For example, the fading control parameters in the preset control parameters can be used to control the electrochromic device, and the fading operation can be completed. For example, the power-replenishing parameters in the preset control parameters can be used to control the electrochromic device, and the power-replenishing operation can be completed (restore the electrochromic device between the coloring state and the fading state to the coloring state or the fading state).

For a standard electrochromic device, the coloring control parameters in the preset control parameters can be used for control, and the coloring operation can be completed, so that the standard electrochromic device is in a coloring state.

Similarly, for a standard electrochromic device, the fading control parameters in the preset control parameters can also be used for control, and the fading operation can be completed, so that the standard electrochromic device is in a faded state.

During the long-term use of the electrochromic device, the electrolyte in the color-changing material inside the electrochromic device will change its characteristics, causing the electrolyte's conduction speed to change, and thus causing the electrochromic device's color-changing ability to change. As a result, the preset control parameters cannot adapt to the color-changing requirements of the electrochromic device after the color-changing ability has changed. For example, using the coloring control parameters to color the electrochromic device, the coloring is darker than that of the standard electrochromic device. For example, using the fading control parameters to fade the electrochromic device, the fading is less thorough than that of the standard electrochromic device. Therefore, it is necessary to reset the preset control parameters to adapt to the color-changing requirements of the electrochromic device after the color-changing ability has changed.

It can be understood that within a reasonable open circuit voltage range, the open circuit voltage of the electrochromic device is positively correlated with the degree of discoloration. That is, during the coloring operation, the larger the coloring open circuit voltage of the electrochromic device, the better the coloring effect. That is, during the fading operation, the larger the fading open circuit voltage of the electrochromic device, the better the fading effect. In other words, the degree of discoloration of the electrochromic device can be judged according to the open circuit voltage.

In one embodiment, the color change degree of the electrochromic device can be determined according to the first open circuit voltage when the electrochromic device completes the color change operation under the control of the coloring control parameter or the fading control parameter.

In one embodiment, the preset control parameters may also include a first closed-circuit voltage of the electrochromic device when the color changing operation is completed. For example, the coloring closed-circuit voltage of the electrochromic device when the coloring operation is completed. For example, the fading closed-circuit voltage of the electrochromic device when the fading operation is completed. In some embodiments, the coloring closed-circuit voltage may be equal to the fading closed-circuit voltage. In some embodiments, the coloring closed-circuit voltage may be unequal to the fading closed-circuit voltage according to the performance requirements of the electrochromic device.

It can be understood that within a reasonable open circuit voltage range, the open circuit voltage of the electrochromic device is positively correlated with the degree of discoloration. That is, during the coloring process, the greater the open circuit voltage of the electrochromic device, the better the coloring effect. That is, during the fading process, the greater the open circuit voltage of the electrochromic device, the better the fading effect. In other words, the degree of discoloration of the electrochromic device can be judged based on the open circuit voltage.

Of course, in order to observe or detect the color change effect of the electrochromic device to a greater extent, the first open circuit voltage when the coloring operation is completed under the control of the coloring control parameter can be preferably used to judge the color change degree of the electrochromic device. Then, a new preset control parameter can be determined according to the first open circuit voltage.

Step S0902: if the first open circuit voltage is less than the second open circuit voltage, the sum of the difference between the second open circuit voltage and the first open circuit voltage plus the first closed circuit voltage is used to replace the first closed circuit voltage in the preset control parameters to update the preset control parameters.

The second open circuit voltage is configured as the open circuit voltage of the standard electrochromic device after the color change operation is performed. For example, the second open circuit voltage is configured as the open circuit voltage of the standard electrochromic device after the color change operation is performed using preset control parameters. Of course, the second open circuit voltage can also be adjusted without limitation.

When the first open circuit voltage is less than and/or equal to the second open circuit voltage, it can be considered that the performance of the electrochromic device has changed and cannot be disqualified as a standard electrochromic device.

For example, in the coloring operation, the coloring open circuit voltage is less than and/or equal to the first sub-open circuit voltage. For example, in the fading operation, the fading open circuit voltage is less than and/or equal to the second sub-open circuit voltage. The first sub-open circuit voltage is configured as the open circuit voltage of the standard electrochromic device after the coloring operation, and the second sub-open circuit voltage is configured as the open circuit voltage of the standard electrochromic device after the fading operation. This indicates that the electrolyte in the color-changing material inside the electrochromic device will change its characteristics, causing the conduction speed of the electrolyte to change, thereby changing the color-changing ability of the electrochromic device. As a result, the current preset control parameters cannot adapt to the color-changing requirements of the electrochromic device after the color-changing ability has changed.

It can be understood that when the first open-circuit voltage is less than and/or the second open-circuit voltage, it indicates that the electrochromic device does not meet the requirements of a standard electrochromic device, which means that the performance of the electrochromic device has changed, making it impossible for the electrochromic device to achieve a color change operation using preset control parameters, or that it can achieve a color change operation but fails to meet the requirements for the corresponding color change degree.

Therefore, it is necessary to adjust and update the preset control parameters in order to better control the color-changing operation of the electrochromic device.

The specific adjustment measure may be to change the closed circuit voltage when the electrochromic device completes the color change operation, for example, to increase the closed circuit voltage.

In one embodiment, the difference between the second open circuit voltage and the first open circuit voltage can be used as the basis for each adjustment. For example, the difference is added to the closed circuit voltage to update the closed circuit voltage. For example, a multiple value of the difference is added to the closed circuit voltage to update the closed circuit voltage.

In one embodiment, please refer to FIG. 10, which discloses a flow chart of a control method for an electrochromic device in another embodiment of the present application. In the control method, steps S0901 and S0902 may be repeated until the first open circuit voltage is greater than the second open circuit voltage, and the updating of the preset control parameters is stopped. The control method can update the preset control parameters so as to better control the color change operation of the electrochromic device, thereby improving the reliability of the electrochromic device.

In one embodiment, please refer to FIG. 11 , which discloses a flow chart of a control method for an electrochromic device in another embodiment of the present application. After step S0902 , the control method further includes:

Step S1101: using the updated preset control parameters to perform a color change operation on the electrochromic device.

In this embodiment, the electrochromic device uses preset control parameters or updated preset control parameters to perform color change operations. When the parameter calibration conditions are met, the preset control parameters are updated. The parameter calibration condition may be that the first open circuit voltage in step S0902 is less than the second open circuit voltage. Of course, another parameter calibration condition may be set before the first open circuit voltage in step S0902 is less than the second open circuit voltage. For example, the parameter calibration condition may be the number of cycles of the electrochromic device. For example, the parameter calibration bar may be a control instruction for receiving manual calibration. Of course, the parameter calibration condition may also be other, which will not be described in detail.

It is understandable that step S0901 can be further performed after step S1101. Of course, step S1101 and step S0901 can be performed simultaneously. In step S0901, after the color changing operation of the electrochromic device is completed using the updated preset control parameters, the first open circuit voltage of the electrochromic device can be obtained. In this way, the preset control parameters can be adjusted and updated anytime and anywhere, so that the reliability of the electrochromic device can be improved.

In one embodiment, the preset control parameters may further include a control time. That is, the preset control parameters may include a control time and a first closed-circuit voltage. The electrochromic device may be applied with the first closed-circuit voltage within the control time to complete the color changing operation.

The control time may include a coloring control time and a fading control time. In some embodiments, the coloring control time may be equal to the fading control time. In some embodiments, the coloring control time may be different from the fading control time according to the performance requirements of the electrochromic device.

The first closed-circuit voltage may include a coloring closed-circuit voltage and a fading closed-circuit voltage. In some embodiments, the coloring closed-circuit voltage may be equal to the fading closed-circuit voltage. In some embodiments, the coloring closed-circuit voltage may be different from the fading closed-circuit voltage according to the performance requirements of the electrochromic device.

For example, when the coloring closed-circuit voltage is equal to the fading closed-circuit voltage, and the coloring control time is equal to the fading control time, a first closed-circuit voltage may be applied to the electrochromic device within the control time to perform a coloring or fading operation.

For example, when the coloring closed-circuit voltage and the fading closed-circuit voltage are not equal, and/or the coloring control time and the fading control time are not equal, the coloring closed-circuit voltage can be applied to the electrochromic device during the coloring control time to perform a coloring operation, and the fading closed-circuit voltage can be applied to the electrochromic device during the fading control time to perform a fading operation.

Correspondingly, in step S0902, the coloring open circuit voltage of the electrochromic device is obtained during the coloring operation, and the coloring open circuit voltage is compared with a second open circuit voltage, for example, the first sub-open circuit voltage, and then the difference between the first sub-open circuit voltage and the coloring open circuit voltage is added to the coloring closed circuit voltage to replace the coloring closed circuit voltage in the preset control parameters. The first sub-open circuit voltage is configured as the open circuit voltage of the standard electrochromic device after the coloring operation.

Correspondingly, in step S0902, the faded open circuit voltage of the electrochromic device is obtained during the fading operation, and the faded open circuit voltage is compared with a second open circuit voltage, such as a second sub-open circuit voltage, and then the difference between the second sub-open circuit voltage and the faded open circuit voltage is added to the faded closed circuit voltage to replace the faded closed circuit voltage in the preset control parameters, and the second sub-open circuit voltage is configured as the open circuit voltage of the standard electrochromic device after the fading operation.

In one embodiment, a comparison test is conducted on a standard electrochromic device and an electrochromic device to be adjusted, and the test is shown in the following table:

It can be seen that for both the electrochromic device to be adjusted and the standard electrochromic device, the coloring operation is performed according to steps S0901 and S0902 using the same preset control parameters (first closed-circuit voltage 0.8V, control time 15s), and the fading operation can also be performed.

The open circuit voltage of the standard electrochromic device (ie, the second open circuit voltage) is 0.5V, and the open circuit voltage of the electrochromic device to be adjusted (ie, the first open circuit voltage) is 0.47V.

Then, the adjusted first closed-circuit voltage=the second open-circuit voltage-the first open-circuit voltage+the first closed-circuit voltage=0.5-0.47+0.8=0.83V.

That is, the adjusted preset control parameters may be the first closed-circuit voltage 0.83V and the control time 15S.

After the preset control parameters of the electrochromic device to be adjusted, the steps shown in any one of FIG. 9 , FIG. 10 and FIG. 11 may be repeated to complete the control of the electrochromic device.

In one embodiment, the preset control parameter may further include a control current. That is, the preset control parameter may include a control current and a first closed-circuit voltage. The electrochromic device may be applied with a control current until the closed-circuit voltage of the electrochromic device is the first closed-circuit voltage, completing the color changing operation. That is, when the closed-circuit voltage of the electrochromic device is the first closed-circuit voltage, the application of the control current is stopped.

The control current may include a coloring control current and a fading control current. In some embodiments, the coloring control current may be equal to the fading control current. In some embodiments, the coloring control current may be different from the fading control current according to the performance requirements of the electrochromic device.

For example, when the coloring closed-circuit voltage and the fading closed-circuit voltage are equal, and the coloring control current and the fading control current are equal, a control current can be applied to the electrochromic device until the closed-circuit voltage of the electrochromic device is the first closed-circuit voltage to complete the coloring or fading operation.

For example, when the coloring closed circuit voltage and the fading closed circuit voltage are not equal, and/or the coloring control current and the fading control current are not equal, the coloring control current is applied to the electrochromic device until the closed circuit voltage of the electrochromic device is the coloring closed circuit voltage to complete the coloring operation. The fading control current is applied to the electrochromic device until the closed circuit voltage of the electrochromic device is the fading closed circuit voltage to complete the fading operation.

Correspondingly, in step S0902, the coloring open circuit voltage of the electrochromic device is obtained during the coloring operation, and the coloring open circuit voltage is compared with a second open circuit voltage, for example, the first sub-open circuit voltage, and then the difference between the first sub-open circuit voltage and the coloring open circuit voltage is added to the coloring closed circuit voltage to replace the coloring closed circuit voltage in the preset control parameters. The first sub-open circuit voltage is configured as the open circuit voltage of the standard electrochromic device after the coloring operation.

Correspondingly, in step S0902, the faded open circuit voltage of the electrochromic device is obtained during the fading operation, and the faded open circuit voltage is compared with a second open circuit voltage, such as a second sub-open circuit voltage, and then the difference between the second sub-open circuit voltage and the faded open circuit voltage is added to the faded closed circuit voltage to replace the faded closed circuit voltage in the preset control parameters, and the second sub-open circuit voltage is configured as the open circuit voltage of the standard electrochromic device after the fading operation.

In one embodiment, a comparison test is conducted on a standard electrochromic device and an electrochromic device to be adjusted, and the test is shown in the following table:

It can be seen that for both the electrochromic device to be adjusted and the standard electrochromic device, the same preset control parameters (first closed-circuit voltage 0.6V, control current 200mA) are used in steps S0901 and S0902 to perform coloring operations, and fading operations can also be performed.

The open circuit voltage of the standard electrochromic device (ie, the second open circuit voltage) is 0.5V, and the open circuit voltage of the electrochromic device to be adjusted (ie, the first open circuit voltage) is 0.48V.

Then, the adjusted first closed-circuit voltage=the second open-circuit voltage-the first open-circuit voltage+the first closed-circuit voltage=0.5-0.48+0.6=0.62V.

That is, the adjusted preset control parameters may be the first closed-circuit voltage 0.83V and the control current 200mA.

After the preset control parameters of the electrochromic device to be adjusted, the steps shown in any one of FIG. 9 , FIG. 10 and FIG. 11 may be repeated to complete the control of the electrochromic device.

In one embodiment, please refer to FIG. 12 , which discloses a flow chart of an electrochromic device control method in another embodiment of the present application. Before step S0901 , the control method further includes:

Step S1201: Detecting the temperature of the electrochromic device.

In order to better update the preset control parameters according to the first open circuit voltage, it is necessary to exclude the influence of other factors on the first open circuit voltage as much as possible. Here, the electrochromic device is similar to a capacitor. The amount of charge determines the first open circuit voltage of the electrochromic device, and then determines the degree of discoloration of the electrochromic device. The mass transfer efficiency of the electrolyte in the color-changing material layer inside the electrochromic device will increase due to excessive temperature and excessive control voltage, and the efficiency of charge transfer will be improved accordingly, which will make the electrolyte reaction speed in the color-changing material layer faster. On the contrary, the reaction speed is slowed down. As a result, the electrochromic device has different response times (ie, control times) at different temperatures and different control voltages.

Therefore, in the process of updating the preset control parameters, it is necessary to weaken the interference caused by temperature as much as possible. Here, the preset temperature range can select the temperature range that has the lowest impact on the electrolyte mass transfer efficiency in the electrochromic device. For example, the preset temperature range can be 20-45°C. Specifically, it can be one of 20°C, 25°C, 30°C, 35°C, 40°C and 45°C. Of course, it can also be adjusted as needed.

It can be understood that when the temperature of the electrochromic device is within the preset temperature range, the preset control parameter update process can be started. Therefore, when the preset temperature range is ensured to be consistent each time, the influence of temperature on the update of the preset control parameters can be appropriately reduced to improve accuracy. Therefore, the preset temperature range can also be other temperatures, as long as it is ensured that the temperature of the electrochromic device is within the same preset temperature range in each preset control parameter update process.

Step S1202: If the temperature is within the preset temperature range, the electrochromic device is subjected to a color changing operation using preset control parameters.

In this embodiment, step S0901 may be performed after step S1202. In one embodiment, step S1201 may be performed after step S1101. In one embodiment, step S1201 may be performed after step S0902.

In one embodiment, please refer to FIG. 13 , which discloses a flow chart of an electrochromic device control method in another embodiment of the present application. Before step S0902 , the method further includes:

Step S1301: using the first open circuit voltage to update the open circuit voltage evaluation parameter.

In the process of updating the preset control parameters, the determination of the first open circuit voltage is involved. However, due to the interference of various factors such as the surrounding environment of the electrochromic device and its own structural materials, the first open circuit voltage obtained once cannot accurately express the color change degree of the electrochromic device in some scenarios.

Therefore, the concept of open circuit voltage evaluation parameters is introduced to weaken the influence of the single measurement of the first open circuit voltage and improve the accuracy of the preset control parameter update process. The corresponding open circuit voltage evaluation parameters can be obtained according to each open circuit voltage, so as to better evaluate the color change degree of the current electrochromic device.

In one embodiment, the first open circuit voltage may be directly used as a new open circuit voltage evaluation parameter.

In one embodiment, the average value of the first open circuit voltages obtained continuously for the most recent multiple times can be used as a new open circuit voltage evaluation parameter. The average value of multiple first open circuit voltages can reduce the influence of other factors on a single first open circuit voltage, and can improve the accuracy of determining the new preset control parameter. Of course, it can also be processed in the form of weighted average. Other methods can also be used, which are not limited here.

The corresponding step S0902 may be: if the updated open circuit voltage evaluation parameter is less than the second open circuit voltage, the first closed circuit voltage in the preset control parameter is replaced by the sum of the difference between the second open circuit voltage and the updated open circuit voltage evaluation parameter and the first closed circuit voltage.

When the open circuit voltage evaluation parameter is less than the second open circuit voltage, it indicates that the electrochromic device cannot be controlled by the preset control parameters to complete the coloring and/or fading operation. This indicates that the color changing ability of the electrochromic device has changed. It also indicates that the preset control strategy needs to be updated.
