Abstract
Description
Technical Field
[0001] This application mainly relates to the technical field of battery temperature measurement, and particularly relates to a battery temperature measurement device. Background Art
[0002] During the battery preparation process, the temperature monitoring and control of the battery are very important. Since the temperature measurement process is usually in a relatively enclosed dark box, related technologies often set temperature detection points in the dark box. When the battery to be measured is transmitted to the temperature detection point, the test program is started and the current temperature of the battery to be measured is read. However, since the time of the battery to be measured at the temperature detection point is short, the stability of the temperature change of the battery to be measured over a long time is lacking. In addition, the ambient temperature inside the dark box cannot be well monitored, resulting in inaccurate and unstable temperature measurement results. Utility Model Content
[0003] The purpose of this application is to provide a battery temperature measurement device that can improve the accuracy and stability of the temperature measurement results of the battery to be measured and the ambient temperature in a convenient and effective manner.
[0004] To achieve the above object, in a first aspect, this application provides a battery temperature measurement device, which is characterized in that it includes a cavity, and the interior of the cavity is provided with a battery to be measured, a first sensor, and a second sensor; the first sensor is spaced from the battery to be measured by a first distance; the second sensor is spaced from the battery to be measured by a second distance, where the first distance is the same as the second distance.
[0005] In some embodiments, the battery to be measured is a perovskite tandem battery or a perovskite single-junction battery.
[0006] In some embodiments, a temperature measurement platform is further provided inside the cavity, and the upper surface of the temperature measurement platform contacts the battery to be measured.
[0007] In some embodiments, a light source is further provided inside the cavity, and the light source is arranged above the temperature measurement platform.
[0008] In some embodiments, the temperature range inside the cavity is 20°C - 30°C.
[0009] In some embodiments, the humidity range inside the cavity is 25% - 35%.
[0010] In some embodiments, the first sensor is an infrared temperature sensor, and / or the second sensor is an infrared temperature sensor.
[0011] In some embodiments, the first sensor and the second sensor are respectively arranged on both sides of the battery to be measured, and the first sensor and the second sensor are on the same straight line.
[0012] In some embodiments, the detected temperature T1 of the first sensor and the detected temperature T2 of the second sensor satisfy the following formula: 2(T1 - T2) / (T1 + T2) ≤ 1%.
[0013] Compared with the prior art, the present application has the following advantages:
[0014] The present application provides a battery temperature measurement device. The surface temperature of the battery to be measured is simultaneously detected by a first sensor arranged at a first distance interval and a second sensor arranged at a second distance interval. Since the first distance is the same as the second distance, the relative temperature at the same distance can be monitored to judge the temperature change stability of the battery to be measured. Both the first sensor and the second sensor are fixed inside the cavity, and the environmental temperature inside the cavity can be accurately detected, thereby ensuring the accuracy and stability of the temperature measurement result in a convenient and effective manner. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] The accompanying drawings are provided to provide a further understanding of the present application, and they are incorporated into and constitute a part of this application. The accompanying drawings illustrate embodiments of the present application and, together with this specification, serve to explain the principles of the present application. In the accompanying drawings:
[0016] Figure 1 is a schematic diagram of a battery temperature measurement device provided by an exemplary embodiment of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the accompanying drawings required for the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings in the following description are only some examples or embodiments of the present application. For those of ordinary skill in the art, without creative efforts, the present application can also be applied to other similar scenarios based on these drawings. Unless obvious from the language context or otherwise stated, the same reference numerals in the drawings represent the same structure or operation.
[0018] As shown in the present application and the claims, unless the context clearly indicates an exception, words such as "a", "an", "one" and / or "the" are not specifically singular and may also include plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of the clearly identified steps and elements, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.
[0019] In the description of this application, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this application and simplifying the description. Without contrary statements, these orientation words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of this application; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.
[0020] For convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper...", etc. can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to cover different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding explanations for the spatial relative descriptions used here are made.
[0021] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional statements, the above words have no special meanings. Therefore, it should not be construed as a limitation on the protection scope of this application. In addition, although the terms used in this application are selected from well-known and commonly used terms, some of the terms mentioned in the specification of this application may be selected by the applicant according to his or her judgment, and their detailed meanings are described in the relevant parts of the description herein. In addition, it is required to understand this application not only through the actual terms used, but also through the meanings implied by each term.
[0022] It should be understood that when a component is referred to as "on another component", "connected to another component", "coupled to another component", or "in contact with another component", it can be directly on, connected to, or coupled to, or in contact with the other component, or there can be an intervening component. In contrast, when a component is referred to as "directly on another component", "directly connected to", "directly coupled to", or "directly in contact with" another component, there is no intervening component. Similarly, when a first component is referred to as "electrically in contact with" or "electrically coupled to" a second component, there is an electrical path allowing current flow between the first component and the second component. The electrical path can include capacitors, coupled inductors, and / or other components allowing current flow, even without direct contact between the conductive components.
[0023] Reference Figure 1 , exemplary embodiments of the present application provide a battery temperature measurement device. The device includes a cavity 1. Inside the cavity 1, there are a battery under test 10, a first sensor 11, and a second sensor 12. The first sensor 11 is spaced from the battery under test 10 by a first distance, and the second sensor 12 is spaced from the battery under test 10 by a second distance, where the first distance is the same as the second distance.
[0024] In some embodiments, the first sensor 11 and the second sensor 12 are respectively disposed on both sides of the battery under test 10, and the first sensor 11 and the second sensor 12 are located on the same straight line.
[0025] For example, continuing to refer to Figure 1 , taking the battery under test 10 as point O, the OX direction represents forward along the battery under test 10, the OY direction represents rightward along the battery under test 10, and the OZ direction represents upward along the battery under test 10. The first distance can be 10 cm, and the first sensor 11 is disposed at the first distance in the front left of the battery under test 10. The second distance can also be 10 cm, and the second sensor is disposed at the second distance in the front right of the battery under test 10.
[0026] Inside the cavity 1, the first sensor 11 and the second sensor 12 can simultaneously detect the surface temperature of the battery under test 10. Since the first distance is the same as the second distance, the relative temperature at the same distance can be monitored to judge the temperature change stability of the battery under test 10. The first sensor 11 and the second sensor 12 can also accurately detect the ambient temperature inside the cavity, thereby ensuring the accuracy and stability of the temperature measurement result in a convenient and effective manner.
[0027] In some embodiments, the first sensor 11 is an infrared temperature sensor, and / or the second sensor 12 is an infrared temperature sensor. The infrared temperature sensor can ensure the accuracy and stability of the temperature measurement result without contacting the battery under test 10.
[0028] The first sensor 11 emits infrared light at a first distance in the front left of the battery 10 to be measured. That is to say, the first sensor 11 detects the temperature at a first distance from the battery 10 to be measured without contact. The second sensor 12 emits infrared light at a second distance in the front right of the battery 10 to be measured. That is to say, the second sensor 11 detects the temperature at a second distance from the battery 10 to be measured without contact. Thus, the temperatures at equivalent distances on both sides of the battery 10 to be measured are detected. On the one hand, by detecting the temperatures at two distance points, the temperature inside the cavity 10 can be determined very accurately and its temperature change can be detected in real time. On the other hand, by comparing the temperatures at equivalent distances on both sides of the battery 10 to be measured, the temperature of the battery 10 to be measured can be accurately known. In particular, the stability of the temperature change of the battery 10 to be measured can be determined, so as to more precisely grasp the preparation process of the battery 10 to be measured.
[0029] In some embodiments, the battery 10 to be measured can be a perovskite tandem cell or a perovskite single-junction cell.
[0030] Continue to refer to Figure 1 , in some embodiments, a temperature measurement platform 13 is further provided inside the cavity 1, and the upper surface of the temperature measurement platform 13 contacts the battery 10 to be measured. A light source 14 is further provided inside the cavity 1, and the light source 14 is arranged above the temperature measurement platform 13.
[0031] The temperature measurement platform 13 itself can realize heating or cooling. Since the upper surface of the temperature measurement platform 13 contacts the battery 10 to be measured, the temperature of the battery 10 to be measured can be increased or decreased.
[0032] In some embodiments, the temperature range inside the cavity 1 is 20°C - 30°C. The humidity range inside the cavity 1 is 25% - 35%. The temperature control and / or humidity control can be realized by circulating air, or can also be realized by other means such as a humidifier and a dehumidifier, and there is no limitation thereto.
[0033] In some embodiments, the detected temperature T1 of the first sensor 11 and the detected temperature T2 of the second sensor 12 satisfy the following formula: 2(T1 - T2) / (T1 + T2) ≤ 1%.
[0034] When 2(T1 - T2) / (T1 + T2) is less than or equal to 1%, it indicates that the temperature change of the battery to be measured is stable. At the same time, the detected temperature T1 of the first sensor 11 and the detected temperature T2 of the second sensor 12 also both represent the ambient temperature at the same distance. Therefore, it can be ensured that the temperature inside the cavity 1 is relatively consistent as a whole and the change range is small, and the accuracy and stability of the temperature measurement result can be ensured.
[0035] In summary, the above battery temperature measurement device simultaneously detects the surface temperature of the battery 10 to be measured through the first sensor 11 and the second sensor 12. Since the first distance is the same as the second distance, it is possible to monitor the relative temperature at the same distance to judge the temperature change stability of the battery 10 to be measured. Both the first sensor 11 and the second sensor 12 are fixed inside the cavity, and can accurately detect the ambient temperature inside the cavity 1, thereby ensuring the accuracy and stability of the temperature measurement result in a convenient and effective manner.
