Referring to fig. 1, fig. 1 shows a schematic diagram of an electrochromic module 100 according to some embodiments of the present disclosure, in which the electrochromic module 100 includes an electrochromic device 110, a first power supply component 120, a second power supply component 130, and a control component 140. The electrochromic device 110 is provided with an electrochromic material therein, and voltages in different directions are applied to the electrochromic device 110 to change the color of the electrochromic device 110, for example, in some embodiments, a voltage in a first direction 150 is applied to the electrochromic device 110 to color the electrochromic device 110, and a voltage in a second direction 160 opposite to the first direction 150 is applied to the electrochromic device 110 to discolor the electrochromic device 110. The first power supply assembly 120 and the second power supply assembly 130 are both used for applying a voltage to the electrochromic device 110, wherein the first power supply assembly 120 is used for applying a voltage in a first direction 150 to the electrochromic device 110, and the second power supply assembly 130 is used for applying a voltage in a second direction 160 to the electrochromic device 110. The control component 140 is used for controlling the first power supply component 120 and the second power supply component 130, so that one of the first power supply component 120 and the second power supply component 130 applies a voltage to the electrochromic device 110. That is, only one of the first power supply assembly 120 and the second power supply assembly 130 applies a voltage to the electrochromic device 110 at the same time under the control of the control assembly 140, and that is, only one of the first direction 150 and the second direction 160 is applied to the electrochromic device 110 at the same time.

In the electrochromic module 100, the first power supply module 120 and the second power supply module 130 are controlled to apply the voltage in the first direction 150 or the second direction 160 to the electrochromic device 110, that is, the output end of one set of power supply modules only needs to apply the voltage in one direction to the electrochromic device 110, and compared with the case that the output end of one set of power supply modules can apply the voltages in two opposite directions to the electrochromic device 110, the circuit design is simpler, and the complexity of the circuit can be greatly reduced. In addition, if the output terminals of one set of power supply components are capable of applying two voltages in opposite directions to the electrochromic device 110, when the line corresponding to the voltage in one direction of the power supply components is damaged, the line corresponding to the voltage in the other direction is usually damaged at the same time, so that the maintenance cost is increased, and the difficulty of maintenance is further increased due to the complicated circuit design. And the two groups of power supply assemblies are controlled to apply voltages in the first direction 150 or the second direction 160 to the electrochromic device 110 respectively, so that the two groups of power supply assemblies are not influenced mutually, the maintenance of the electrochromic module 100 is facilitated, and the safety and the service life of the electrochromic module 100 are improved.

It should be noted that, in the present application, the description of coloring the electrochromic device 110 may be understood as coloring or discoloring the electrochromic device 110, thereby changing the light transmittance of the electrochromic device 110 and further changing the light adjusting function of the electrochromic device 110. For example, in some embodiments, when the electrochromic device 110 is applied to the electrochromic window 200, when the electrochromic device 110 is colored, the intensity of the ambient light emitted from the outdoor to the indoor through the electrochromic window 200 is reduced, and when the electrochromic device 110 is discolored, the intensity of the ambient light emitted from the outdoor to the indoor through the electrochromic window 200 is increased, thereby implementing the function of adjusting the indoor light intensity. Also, in the present application, it is described that the electrochromic device 110 is colored, either the transparent electrochromic device 110 or the electrochromic device 110 having a lighter color is changed to a darker color, and the electrochromic device 110 is discolored, either the electrochromic device 110 having a color is discolored to be transparent or the electrochromic device 110 having a darker color is discolored to be a lighter color.

Further, in some embodiments, the control module 140 includes a photosensitive sensor 141 and a control chip 142, the photosensitive sensor 141 can detect the intensity of the ambient light and convert the intensity information of the ambient light into an electrical signal to be transmitted to the control chip 142, and the control chip 142 controls one of the first power supply module 120 and the second power supply module 130 to apply a voltage to the electrochromic device 110 according to the intensity information of the ambient light.

Specifically, in some embodiments, the electrochromic device 110 colors when the first power supply assembly 120 applies a voltage in the first direction 150 to the electrochromic device 110, and the electrochromic device 110 fades when the second power supply assembly 130 applies a voltage in the second direction 160 to the electrochromic device 110. And, when the electrochromic device 110 is used on an electrochromic window, the photosensor 141 is disposed indoors for detecting the light intensity of the indoor environment. The control component 140 is provided with a light intensity threshold, when the light intensity of the ambient light detected by the photosensor 141 is greater than the light intensity threshold, it can be understood that the light intensity of the indoor environment is stronger at this time, the control component 140 controls the first power supply component 120 to apply a voltage in the first direction 150 to the electrochromic device 110, so that the electrochromic device 110 is colored, and further the light intensity of the outdoor ambient light emitted into the indoor space from the outdoor space through the electrochromic device 110 is reduced, so that the indoor light intensity is controlled to a certain degree, and discomfort of a human body caused by the overlarge indoor light intensity is avoided. In addition, when the light intensity of the ambient light is less than the light intensity threshold, it can be understood that the light intensity of the indoor environment is weak at this time, the control component 140 controls the second power supply component 130 to apply a voltage in the second direction 160 to the electrochromic device 110, so that the electrochromic device 110 fades, and further, the light intensity of the outdoor ambient light emitted from the outdoor to the indoor through the electrochromic device 110 is enhanced, thereby preventing the visual effect from being influenced by too small indoor light intensity.

Of course, when different electrochromic materials are used in the electrochromic device 110, the electrochromic device 110 can also have different color-changing effects for different directional voltages. For example, in other embodiments, the electrochromic device 110 fades when the first power supply assembly 120 applies a voltage in the first direction 150 to the electrochromic device 110, and the electrochromic device 110 colors when the second power supply assembly 130 applies a voltage in the second direction 160 to the electrochromic device 110. At this time, when the light intensity of the ambient light detected by the photosensor 141 is greater than the light intensity threshold, the control component 140 controls the second power supply component 130 to apply the voltage in the second direction 160 to the electrochromic device 110, and when the ambient light detected by the photosensor 141 is less than the light intensity threshold, the control component 140 controls the first power supply component 120 to apply the voltage in the first direction 150 to the electrochromic device 110, so as to control the light intensity of the indoor environment within a certain range, and prevent the indoor light intensity from being too large or too small.

It is understood that in the present application, the power supply assembly applies a voltage to the electrochromic device 110 through two output terminals, and the two output terminals are respectively a positive electrode and a negative electrode, the voltage in the first direction 150 is understood that the positive electrode of the power supply assembly points to the negative electrode in the same direction as the first direction 150, and the voltage in the second direction 160 is understood that the positive electrode of the power supply assembly points to the negative electrode in the same direction as the second direction 160.

In addition, in other embodiments, when the electrochromic device 110 is applied to an electrochromic window, the photosensitive sensor 141 may also be disposed outdoors for detecting the intensity of the outdoor ambient light, and the control chip 142 controls the color change of the electrochromic device 110 according to the intensity of the outdoor ambient light. More specifically, in some embodiments, when the indoor light intensity is mainly from the indoor light source and the outdoor light source only provides auxiliary lighting for the indoor light source, the photosensitive sensor 141 may be disposed indoors to control the color change of the electrochromic device 110 according to the light intensity of the indoor environment, and when the indoor light intensity is mainly from the outdoor ambient light, the photosensitive sensor 141 may be disposed outdoors to control the color change of the electrochromic device 110 according to the light intensity of the outdoor ambient light. Moreover, it can be understood that the light intensity threshold set by the photosensitive sensor 141 is not limited, and can be specifically set according to the indoor lighting requirement and the personal requirement of the user, when the light intensity of the indoor environment is required to be greater, the light intensity threshold can be relatively increased, and when the light intensity of the indoor environment is required to be smaller, the light intensity threshold can be relatively decreased.

Of course, in some embodiments, the voltage may also be applied to the electrochromic device 110 by manually controlling the first power supply assembly 120 or the second power supply assembly 130 to meet more requirements of different users. Specifically, in some embodiments, the control assembly 140 further includes a first switching element 143, a second switching element 144, and a third switching element 145, and the switching elements each have a closed state and an open state. The third switch 145 is disposed between the photosensitive sensor 141 and the circuit of the control chip 142, when the third switch 145 is in a closed state, the photosensitive sensor 141 is connected to the control chip 142, the control chip 142 controls the first power supply module 120 and the second power supply module 130 according to the intensity of the ambient light detected by the photosensitive sensor 141, and when the third switch 145 is in an open state, the electrical connection between the photosensitive sensor 141 and the control chip 142 is disconnected. Moreover, when the electrical connection between the photosensitive sensor 141 and the control chip 142 is disconnected, if the first switch element 143 is in a closed state, the first power supply component 120 applies a voltage in the first direction 150 to the electrochromic device 110, and if the second switch element 144 is in a closed state, the second power supply component 130 applies a voltage in the second direction 160 to the electrochromic device 110.

Therefore, when the color of the electrochromic device 110 needs to be manually controlled, the third switching element 145 can be turned off, and one of the first switching element 143 and the second switching element 144 can be manually controlled to be in a closed state, so that the color of the electrochromic device 110 can be manually controlled. Of course, at this time, it is required to ensure that only one of the first switch element 143 and the second switch element 144 is in the closed state and the other is in the switched state, that is, the states of the first switch element 143 and the second switch element 144 should be opposite to each other at the same time, so as to avoid the mutual interference between the first power supply assembly 120 and the second power supply assembly 130.

Further, in some embodiments, the first power supply assembly 120 includes a first solar panel 121 and a first power storage device 122, and the second power supply assembly 130 includes a second solar panel 131 and a second power storage device 132. The first solar cell panel 121 and the second solar cell panel 131 are both disposed in an area where there is a sufficient amount of outdoor illumination, and are configured to convert solar energy into electrical energy. The first power storage device 122 is used for storing the electric energy converted by the first solar cell panel 121 and applying a voltage in a first direction 150 to the electrochromic device 110, and the second power storage device 132 is used for storing the electric energy converted by the second solar cell panel 131 and applying a voltage in a second direction 160 to the electrochromic device 110. The solar cell panel is used as a power supply of the power supply assembly, renewable energy sources can be fully utilized, and the working cost of the electrochromic device 110 is saved. In addition, it can be understood that the electric energy converted by the solar cell panel is limited, and when a set of power supply assemblies is conventionally used to apply voltages in different directions to the electrochromic device 110, the power supply assemblies continuously work and are prone to being incapable of operating normally due to insufficient electric energy, which affects the performance of the electrochromic module 100. The electrochromic module 100 of the present application applies voltages in two directions to the electrochromic device 110 by using two sets of power supply assemblies, and when one set of power supply assembly applies a voltage to the electrochromic device 110, the other set of power supply assembly does not supply power, so that the two sets of power supply assemblies alternately apply a voltage to the electrochromic device 110, and the situation that the normal operation of the electrochromic module 100 is affected due to insufficient electric energy converted by the solar cell panel can be better avoided.

Further, in some embodiments, the first power supply assembly 120 further includes a first backup power source 125, and the first backup power source 125 is electrically connected to the first power storage device 122 for assisting the first power storage device 122 to apply a voltage in the first direction 150 to the electrochromic device 110. For example, in a weather where sunlight is not sufficiently irradiated, such as a cloudy day or a rainy day, the electric power converted by the first solar panel 121 is insufficient, and the voltage applied to the electrochromic device 110 by the first power storage device 122 is likely to be insufficient, and here, the normal operation of the first power storage device 122 can be ensured by charging the first power storage device 122 with the first backup power supply 125. Similarly, in some embodiments, the second power supply assembly 130 further includes a second backup power source 135, which is used to assist the second power storage device 132 to apply the voltage in the second direction 160 to the electrochromic device 110, so as to prevent the performance of the electrochromic module 100 from being affected by the insufficient voltage of the second power storage device 132.

Referring to fig. 1 and 2, fig. 2 is a schematic diagram of an electrochromic device 110 in some embodiments of the present disclosure, where the electrochromic device 110 includes a first substrate 111, a first conductive layer 112, an ion storage layer 113, an ion transport layer 114, an electrochromic layer 115, a second conductive layer 116, and a second substrate 117, which are sequentially arranged along a first direction 150. The first substrate 111 and the second substrate 117 may be plastic or glass, and are used for carrying and protecting a layer structure sandwiched between the first substrate 111 and the second substrate 117. The first conductive layer 112 and the second conductive layer 116 are electrically connected to the first power storage device 122 and the second power storage device 132, and the first power storage device 122 and the second power storage device 132 apply a voltage to the layer structure interposed between the first conductive layer 112 and the second conductive layer 116 through the first conductive layer 112 and the second conductive layer 116. The ion storage layer 113 is used to store ions (not shown) capable of discoloring the electrochromic layer 115, and an electrochromic material is disposed in the electrochromic layer 115, and when ions are injected into the electrochromic layer 115 from the ion storage layer 113 or extracted from the electrochromic layer 115 and enter the ion storage layer 113, the electrochromic layer 115 is discolored. The ion transport layer 114 is used for exchanging ions between the electrochromic layer 115 and the ion storage layer 113.

It should be noted that, in some embodiments, the first power supply assembly 120 outputs a voltage through two output terminals of the first power storage device 122, the two output terminals of the first power storage device 122 are a first positive electrode 123 and a second negative electrode 134, respectively, and when the first power storage device 122 applies a voltage in the first direction 150 to the electrochromic device 110, the first positive electrode 123 is electrically connected to the first conductive layer 112, and the first negative electrode 124 is electrically connected to the second conductive layer 116. Similarly, the two output terminals of the second power storage device 132 are a second positive electrode 133 and a second negative electrode 134, respectively, and the second positive electrode 133 is electrically connected to the second conductive layer 116, and the second negative electrode 134 is electrically connected to the first conductive layer 112.

Specifically, in some embodiments, the color-changing material in the electrochromic layer 115 may be an inorganic electrochromic material such as tungsten trioxide or nickel oxide, or may be an organic electrochromic material such as polythiophene compound and its derivative, viologen compound, tetrathiafulvalene, or metal phthalocyanine compound. The ions stored in the ion storage layer 113 may be hydrogen ions, lithium ions, sodium ions, potassium ions, or the like. The material of the ion transport layer 114 may be a liquid dielectric, a gel electrolyte, or a solid dielectric. The material of the first conductive layer 112 and the second conductive layer 116 may be a material having excellent conductive performance, such as a metal or an organic polymer conductive material.

Also, in some embodiments, when the electrochromic material in the electrochromic layer 115 is a cathode electrochromic material, if ions stored in the ion storage layer 113 are injected into the electrochromic layer 115 through the ion transport layer 114, the electrochromic layer 115 is colored, and if ions are extracted from the electrochromic layer 115 and enter the ion storage layer 113 through the ion transport layer 114, the electrochromic layer 115 is discolored. For example, in some embodiments, the electrochromic material in electrochromic layer 115 is a cathodic electrochromic material, tungsten trioxide, and the ions are lithium ions. At this time, when the first power storage device 122 applies a voltage in the first direction 150 to the electrochromic device 110, ions in the ion storage layer 113 are injected into the electrochromic layer 115 by the voltage to color the electrochromic layer 115. And when the second power storage device 132 applies a voltage in the second direction 160 to the electrochromic device 110, ions are extracted from the electrochromic layer 115 and enter the ion storage layer 113, discoloring the electrochromic layer 115.

Of course, the ions can also have different effects on the color of the electrochromic layer 115 when the electrochromic material in the electrochromic layer 115 is changed. For example, in some embodiments, the electrochromic material in electrochromic layer 115 is an anodic electrochromic material such as nickel oxide, and the ions are lithium ions. At this time, when the second power storage device 132 applies a voltage in the second direction 160 to the electrochromic device 110, ions are extracted from the electrochromic layer 115 and enter the ion storage layer 113, causing the electrochromic layer 115 to be colored, and when the first power storage device 122 applies a voltage in the first direction 150 to the electrochromic device 110, ions are injected from the ion storage layer 113 into the electrochromic layer 115, causing the electrochromic layer 115 to be colored. It is understood that, at this time, when the intensity of the ambient light detected by the photosensor 141 is greater than the light intensity threshold, the control chip 142 controls the second electric storage device 132 to apply the voltage in the second direction 160 to the electrochromic device 110; and when the intensity of the ambient light detected by the photosensor 141 is less than the light intensity threshold, the control chip 142 controls the first power storage device 122 to apply a voltage in the first direction 150 to the electrochromic device 110.

Further, referring to fig. 1 and 3, in some embodiments, the electrochromic module 100 may be applied to an electrochromic window 200, and the color of the electrochromic window 200 is changed by changing the color of the electrochromic device 110, so that the electrochromic window 200 has an effect of adjusting the indoor ambient light intensity. Specifically, the electrochromic window 200 may include a first glass 210 and a second glass 220, the electrochromic device 110 is sandwiched between the first glass 210 and the second glass 220, and the first glass 210 and the second glass 220 protect the electrochromic device 110. It can be understood that, in this case, the output terminals of the first power supply module 120 and the second power supply module 130 need to extend into the space between the first glass 210 and the second glass 220 through the leads, so as to apply a voltage to the electrochromic layer 115.
