According to the embodiment of the invention, the plurality of independently operated light emitting sources are adopted, and part of the light emitting sources are selectively turned on according to the shape and the size of the battery assembly or the local area to be tested of the battery assembly, so that illumination only covers the battery assembly or the local area to be tested of the battery assembly, the testing accuracy and the testing efficiency of the battery assembly are improved, and the energy consumption can be reduced.
An embodiment of the present invention is described below with reference to fig. 1.

The light source assembly 3 comprises a plurality of independently operated light emitting sources, and the light emitting sources are steady-state light sources; the plurality of luminous sources are arranged on the upper surface of the frame 1 and mutually spliced to form a luminous plane facing the placing table 2. The light source assembly 3 is adapted to switch on at least part of the light source depending on the irradiation area of the battery assembly 7.
According to the battery assembly testing device provided by the embodiment of the invention, the plurality of independently operated light emitting sources are adopted, and the corresponding light emitting sources can be selectively turned on according to the irradiation area of the battery assembly 7, namely the shape and the size of the battery assembly 7 and the local area of the battery assembly 7 to be tested, so that illumination only covers the irradiation area of the battery assembly 7, the testing accuracy and the utilization rate of the light emitting sources are improved, the testing efficiency is improved, and the energy consumption and the use cost are also reduced.
It is contemplated that some of the cell assemblies 7 may have significant shading characteristics, such as cadmium telluride thin film assemblies. Such battery packs require a long irradiation of a constant light source to achieve their performance. In order to improve the testing accuracy of the battery assembly 7 with obvious bright and dark characteristics, the luminous source is a steady-state light source, and the relatively real working environment of the battery assembly 7 can be simulated.
In addition, set up lighter battery pack 7 and place the platform 2 in the upper end, conveniently place battery pack 7, be convenient for operate, set up heavier light source module 3 and frame 1 in the lower extreme, reduced the focus of complete machine, do benefit to the stability that improves battery pack testing arrangement.
The battery assembly testing device provided by the embodiment of the invention can test various battery assemblies 7 with different shapes and sizes, and effectively improves the application range of the battery assembly testing device. In addition, the embodiment of the invention can also perform targeted test on the local area of the battery assembly 7. For example, the corresponding part of the light source is turned on, so that the illumination only covers a local area of the battery assembly 7, and part of the special test requirements are met. The number of the luminous sources is small, and the heating value is small, so that the problem of large-range temperature rise can be avoided.
Specifically, the chassis 1 is used to support the placement stage 2 and the light source assembly 3. The placement stage 2 is made of a transparent material with high transmittance to reduce its irradiation influence on the light source irradiating the battery assembly 7. For example, the placement stage 2 may be made of tempered glass. In order to effectively fix a plurality of light-emitting sources of the light source assembly 3, a mounting groove is formed in the upper surface of the frame 1 to form a bearing platform for the light-emitting sources, and the light-emitting sources are horizontally arranged in the mounting groove. Light emitted from the light source is vertically and upwardly irradiated on the battery assembly 7 through the placement table 2.
Specifically, in some special application scenarios, the battery assembly 7 is shaped differently, forming a shaped battery assembly, such as a strip, a sector, a triangle, a torus, a hexagon, a rectangular ring, etc. The embodiment of the invention can select the corresponding part of the luminous sources to be started according to the specific shape and the size of the battery assembly 7, so that the luminous sources only irradiate the surface of the battery assembly 7 and cannot irradiate other areas.
In one embodiment, the light emitted by the light source is directed toward the bottom surface of the placement stage 2. The placement table 2 is provided with a plurality of detection areas, and the detection areas uniformly and uniformly correspond to the shapes and the sizes of the luminous sources. The placing table 2 is provided with a plurality of detection areas, the shape and the size of the battery assembly 7 can be obtained according to the positions and the number of the detection areas covered by the battery assembly 7, then the battery assembly can be tested by only starting the luminous source corresponding to the covered detection areas, the utilization rate of the luminous source is high, and the energy consumption is low. Other light-emitting sources do not need to be turned on, and the battery assembly 7 is prevented from being affected by the other light-emitting sources, so that the testing accuracy of the battery assembly 7 is improved.
For example, the light source assembly 3 includes 36 independently operated light emitting sources, and 36 detection areas of the same shape and size are correspondingly provided. When the battery assembly 7 is placed on the placement table 2, only 16 detection areas are covered, and only 16 corresponding light-emitting sources are required to be turned on during detection. To facilitate batch testing, the same type of battery assembly 7 may be tested by selecting a fixed location of the test area.
In one embodiment, the light source assembly 3 includes a plurality of surface light sources 301 and a plurality of line light sources 302. The plurality of surface light sources 301 are spliced with each other by the plurality of line light sources 302 to form a light emitting plane. The surface light source 301 and the line light source 302 are both steady-state light sources. The surface light source 301 can be adapted to the planar battery plate of the battery assembly 7. The plurality of surface light sources 301 can be quickly spliced into a light emitting plane with a larger area, and the irradiation is uniform. The line light source 302 may fill the gap between the surface light sources 301 to form a complete light emitting plane. The corresponding surface light source 301 and the line light source 302 are turned on, respectively, according to the shape and size of the battery assembly 7, thereby realizing that the illumination of the light source assembly 3 covers only the battery assembly 7. Compared with the traditional transient pulse light source, the surface light source 301 and the linear light source 302 adopted by the invention are steady-state light sources, can simulate the relatively real working environment of the battery assembly 7, are suitable for the battery assembly 7 with obvious bright and dark characteristics, can obviously reduce test errors and improve test accuracy.
Since the general battery assembly 7 is generally formed by mutually connecting a plurality of rectangular battery pieces in series, gaps are left between the plurality of battery pieces. The above-mentioned shaped battery assembly is also generally formed by mutually serially splicing a plurality of rectangular battery plates. To facilitate testing of the power generation performance of each of the battery cells of the battery assembly 7, in one embodiment, the surface light source 301 has a rectangular shape corresponding to the battery cells, and the line light source 302 has a linear shape corresponding to the gaps between the battery cells. Each surface light source 301 irradiates a battery piece correspondingly, and the linear light source 302 irradiates gaps between the battery pieces, so that the testing efficiency and accuracy of the battery assembly testing device can be further improved. The battery pieces can be arranged in a one-to-one correspondence with the detection areas.

The surface light source 301 and the linear light source 302 are both LED modularized light sources, so that the energy consumption is low, the service life is long, the use cost is low, and the popularization is facilitated.
In one embodiment, each surface light source 301 is provided with a first switch, and each line light source 302 is provided with a second switch. The first switch may be used to control the on and off of each surface light source 301, and the second switch may be used to control the on and off of each line light source 302, so as to control the on and off of a portion of the surface light source 301 and the line light source 302 according to the shape and size of the battery assembly 7 to be tested, respectively, so that only the irradiation area required by the battery assembly 7 is irradiated.
It should be noted that, the first switch and the second switch may be manually controlled by a person, and an operator correspondingly and manually controls the first switch and the second switch according to the positions and the number of the detection areas covered by the battery assembly 7, and turns on the corresponding surface light source 301 and the line light source 302, so as to reduce the use cost.
In one embodiment, the battery assembly testing device further includes a controller (not shown in the figure), and the plurality of light emitting sources are respectively electrically connected to the controller, and the controller is adapted to correspondingly turn on the light sources according to the number and positions of the coverage detection areas of the battery assembly 7. The controller can be used for realizing automatic control of the luminous source, reducing errors caused by manual operation and further improving the testing accuracy and the testing efficiency of the battery assembly 7.
Further, the battery pack testing device further comprises a battery pack sensing unit, and the battery pack sensing unit is electrically connected with the controller. The battery assembly sensing unit is used for detecting the number and the positions of the coverage detection areas of the battery assembly 7, sending the detection results to the controller in an electric signal mode, and controlling the corresponding luminous sources to be started according to the number and the positions of the coverage detection areas of the battery assembly 7 detected by the battery assembly sensing unit, so that the operation is convenient.
The battery assembly sensing unit comprises a plurality of pressure-sensitive sensors, and each detection area is provided with at least one pressure-sensitive sensor and corresponding position coordinates. When the battery pack 7 is placed on the placement table 2, the covered detection areas are pressed, the pressure-sensitive sensor detects signals corresponding to the detection areas covered by the battery pack 7, and then the pressed signals and the position coordinates are sent to the controller, and the controller obtains the number and the positions of the covered detection areas of the battery pack 7.
In one embodiment, the battery assembly testing device further comprises a lifting mechanism 4, wherein the lifting mechanism 4 is arranged between the placing table 2 and the frame 1 and is used for driving the placing table 2 to lift so as to adjust the interval between the placing table 2 and the frame 1, and the lifting mechanism 4 is electrically connected with the controller. The placing table 2 is driven to move up and down relative to the frame 1 by the lifting mechanism 4, and irradiance of the light-emitting source to the battery assembly 7 to be tested can be adjusted, so that power generation performance of the battery assembly 7 under different irradiance can be simulated and tested.
It should be noted that, the embodiment of the present invention does not limit the specific structure of the lifting mechanism 4, as long as the lifting mechanism 4 can drive the placement table 2 to move up and down relative to the frame 1. For example, as shown in fig. 1, the lifting mechanism 4 may employ a scissor-type four-bar mechanism. The lower ends of the two groups of four-bar mechanisms are respectively fixedly arranged on two sides of the frame 1, and the upper ends of the two groups of four-bar mechanisms are fixedly connected with two sides of the placing table 2. The state of the two groups of four-bar mechanisms is synchronously changed, so that the height of the placing table 2 in the vertical direction is adjusted, the structure is simple, the use is convenient, and the irradiation effect of the light-emitting source is not influenced.
The fixing of the lifting mechanism 4 to the placement table 2 and the frame 1 may be detachable or may be fastened. The fastening type fixing manner is more stable than the detachable fixing manner, and thus, in the embodiment of the present invention, the fastening type fixing manner is adopted, for example, the lifting mechanism 4 is integrally connected with the placement table 2 and the frame 1 by welding.
In other embodiments, the lifting mechanism 4 may be a mast, a sleeve, or other conventional lifting mechanism.
In one embodiment, the placement stage 2 is provided with a plurality of irradiance detectors, each of which is electrically connected to a controller and adapted to feed back irradiance received by the battery assembly 7.

The light source emits light while generating heat, and the battery assembly 7 with obvious bright and dark characteristics such as a cadmium telluride thin film assembly requires long-time constant illumination, so that the light source needs to be subjected to heat dissipation treatment.

For example, the light source adopts an LED modularized light source, the spectrum of the light source is close to that of solar rays, and the light source can be directly used for simulating the solar rays. When the battery assembly 7 needs to simulate the light of the incandescent lamp, a corresponding filter is needed to be selected at this time to filter part of the light of the LED modularized light source, so that the light irradiating the battery assembly 7 is similar to the spectrum of the incandescent lamp, thereby simulating the light of the incandescent lamp.
In addition, it should be noted that the embodiment of the present invention is mainly used in the testing stage of the battery assembly 7, and the appearance and the power generation requirements of the user on the battery assembly 7 can be simulated through the optical filter, so as to detect the influence of the requirements on the battery assembly 7. For example, some customers need to cover a blue or red film on the battery assembly 7, and the blue or red film can be simulated by the filter, so that the power generation performance of the battery assembly 7 after the blue or red film is covered is tested, and the result is fed back to the user in the testing stage, and the user can select the color with less influence on the power generation performance to be covered according to the test result.
Further, the filter is detachably covered on the upper surfaces of the plurality of light emitting sources.

According to the embodiment of the invention, the corresponding filter can be selected to be replaced according to the test requirement of the battery assembly 7 so as to filter the light rays of the light emitting source, and different illumination environments can be simulated only by replacing the filter, so that the light emitting source is not required to be replaced, and the use is convenient. It should be noted that, the embodiments of the present invention are not limited to the filter, and the filter may be made of filter glass.
