[0027] Reference Figure 1 、 Figure 2 and Figure 3 The battery functional test tray of the first embodiment of the present invention includes: a support frame 2, a fixed plate 3, a sliding plate 4, and a detection device 8. The support frame is used to place the battery 1; the fixed plate 3 is fixedly set on the support frame 2; the sliding plate 4 is slidably set on the support frame 2, and the sliding plate 4 can slide relative to the support frame 2 along a first direction. The sliding plate 4 and the fixed plate 3 are spaced apart along the first direction to clamp the battery 1. When the battery 1 is installed on the battery 1 testing equipment, in order to adapt to the size of the battery 1, the sliding plate 4 is slid forward so that the sliding plate 4 is away from the fixed plate 3, thereby increasing the distance between the sliding plate 4 and the fixed plate 3. Then, the battery 1 is placed between the fixed plate 3 and the sliding plate 4, and then the battery 1 is clamped between the fixed plate 3 and the sliding plate 4 by moving the sliding plate 4, and the sliding plate 4 is fixed in the clamping position, so that batteries 1 of different sizes can be clamped by the battery 1 testing equipment.

[0028] The detection device 8 is set on the support frame 2. The detection device 8 is provided with a first interface 81, a second interface 82, a third interface 83 and a fourth interface 84. The first interface 81 and the second interface 82 are connected to the positive electrode of the battery 1, and the third interface 83 and the fourth interface 84 are connected to the negative electrode of the battery 1. The first interface 81 and the third interface 83 are used to measure the current of the battery 1, and the second interface 82 and the fourth interface 84 are used to collect the voltage of the battery 1. When testing different items of the battery 1, the connection method of the positive and negative electrodes of the battery 1 is different. Among them, when testing the current, power or charge and discharge of the battery 1, a larger current is required. At this time, the connection method formed requires that the battery 1 has current passing after the first interface 81 and the third interface 83 are connected. When testing the voltage performance of the battery 1, only the voltage needs to pass, that is, after the second interface 82 and the third interface 83 are connected, the voltage of the battery 1 can pass. The first interface 81, the second interface 82, the third interface 83 and the fourth interface 84 are connected to the positive and negative poles of the battery 1 in different ways, so that when the current or voltage of the battery 1 is detected, it is only necessary to connect to the first interface 81, the second interface 82, the third interface 83 and the fourth interface 84, without directly connecting to the positive and negative poles of the battery 1, thereby avoiding wear of the positive and negative poles of the battery 1.

[0029] Wear of the connection ports of the battery cell 11 may bring many kinds of hazards. Reduced charging efficiency: Worn ports may cause poor contact, which hinders the current transmission process and thus reduces the charging efficiency. Unstable charging: Wear may also cause intermittent charging, or even failure to charge, causing inconvenience to the user. Damage to the health of battery 1: Frequent charging problems may increase the burden on the inside of battery 1, causing the performance of battery 1 to deteriorate and shorten the service life of battery 1. Increased safety risks: Worn ports may be more likely to cause safety hazards such as short circuits, posing a threat to the safety of the device and users. In summary, the wear of the connection ports of the battery cell 11 will not only affect the normal use of the device, but may also cause damage to the performance of battery 1, data transmission, and user safety. Even during the detection of battery 1, the measurement results may be inaccurate due to wear.

[0030] According to some embodiments of the present invention, a first slide rail 5 is further included. The first slide rail 5 is arranged on the support frame 2 along a first direction, and the sliding plate 4 is slidably arranged on the first slide rail 5. In order to limit the sliding direction of the sliding plate 4, namely the first direction, the spacing between the sliding plate 4 and the fixed plate 3 can be adjusted more conveniently. At the same time, the provision of the slide rail can also better control the sliding direction of the sliding plate 4 and the installation direction of the sliding plate 4. It can further ensure that the side of the sliding plate 4 facing the fixed plate 3 remains perpendicular to the sliding direction of the sliding plate 4, thereby achieving a better fit with the surface of the battery 1 when clamping the battery 1.

[0031] According to some embodiments of the present invention, the battery 1 is further clamped by a first clamping plate 71 and a second clamping plate 72. The first clamping plate 71 and the second clamping plate 72 are disposed on the fixed plate 3 and / or the sliding plate 4. The first clamping plate 71 and the second clamping plate 72 are spaced apart in the second direction to clamp the battery 1. The first clamping plate 71 and the second clamping plate 72 are further disposed on the fixed plate 3. When the battery 1 is placed on the battery 1 device, the first clamping plate 71 and the second clamping plate 72 are first moved away from each other in the second direction, thereby increasing the spacing between the first clamping plate 71 and the second clamping plate 72. After the battery 1 is placed between the first clamping plate 71 and the second clamping plate 72, the first clamping plate 71 and the second clamping plate 72 are moved so that the first clamping plate 71 and the second clamping plate 72 are brought closer together to clamp the battery 1, thereby clamping and securing the battery 1. Specifically, after the first clamping plate 71 and the second clamping plate 72 clamp the battery 1 in the second direction, the sliding plate 4 is moved and cooperates with the fixed plate 3 to clamp the battery 1 in the first direction. Furthermore, the first defense line is arranged perpendicular to the second direction, so that the battery 1 is clamped more firmly.

[0032] According to some embodiments of the present invention, a second slide rail 6 is further included. The second slide rail 6 is arranged on the fixed plate 3 and arranged along the second direction. The first clamping plate 71 and the second clamping plate 72 are slidably arranged on the second slide rail 6. The second slide rail 6 is arranged on the fixed plate 3 to limit the sliding direction of the first clamping plate 71 and the second clamping plate 72, so that the adjustment of the spacing between the first clamping plate 71 and the second clamping plate 72 is more convenient. At the same time, after the second slide rail 6 is arranged, the sliding direction of the first clamping plate 71 and the second clamping plate 72 and the setting direction of the two can be better controlled. It can further make the two surfaces of the first clamping plate 71 and the second clamping plate 72 that are close to each other remain perpendicular to the second direction, so that when clamping the battery 1, they can better fit the surface of the battery 1.

[0033] According to some embodiments of the present invention, the detection device 8 also includes a positive power line 85 and a negative power line 86, the positive power line 85 connects the first interface 81 and the positive pole of the battery 1, and the negative power line 86 connects the third interface 83 and the negative pole of the battery 1 to collect the current of the battery 1. When charging and discharging the battery 1 and measuring the power, the measuring instrument can be connected to the first interface 81 and the third interface 83 to achieve the measurement of the battery 1. Such measurement requires a large current to pass through the circuit, so the positive power line 85 and the negative power line 86 are set for the current to pass through. Specifically, the conductors with a larger rated current are used as the positive power line 85 and the negative power line 86.

[0034] According to some embodiments of the present invention, the detection device 8 further includes a positive voltage line 87 and a negative voltage line 88, wherein the positive voltage line 87 connects the first interface 81 and the positive electrode of the battery 1, and the negative voltage line 88 connects the third interface 83 and the negative electrode of the battery 1, so as to collect the voltage of the battery 1. When measuring the voltage of the battery 1, a measuring instrument can be connected to the second interface 82 and the fourth interface 84 to achieve measurement of the battery 1. Such measurement only requires the voltage to pass through the circuit, so when setting the positive voltage line 87 and the negative voltage line 88 as conductors, only thinner conductors are required.

[0035] According to some embodiments of the present invention, the detection device 8 also includes an internal pressure measuring component to measure the air pressure inside the battery 1. Specifically, the internal pressure measuring component includes an internal pressure gauge 91, an internal pressure pipe and an internal pressure connection interface 92. The internal pressure pipe connects the interior of the battery 1 with the internal pressure gauge 91, so that the internal pressure gauge 91 measures the air pressure inside the battery 1. The internal pressure gauge 91 is electrically connected to the internal pressure connection interface 92. The internal pressure pipe connects the interior of the battery 1 and the internal pressure gauge 91, so that the internal pressure gauge 91 can measure the voltage inside the battery 1. At this time, the voltmeter can either transmit the air pressure value inside the battery 1 through an electrical signal or directly display the value through an instrument. When the internal pressure gauge 91 transmits the air pressure value inside the battery 1 through an electrical signal, an internal pressure connection interface 92 is set. The plug end of the internal pressure connection interface 92 is connected to the internal pressure gauge 91, and the interface end of the internal pressure connection interface 92 is connected to other instruments.

[0036] According to some embodiments of the present invention, the battery 1 includes a battery cell 11 and a clamping plate 12, the battery cell 11 is arranged between the clamping plate 12, and the detection device 8 also includes an external pressure measurement component to measure the pressure between the battery cell 11 and the clamping plate 12, the external pressure measurement component includes a pressure sensor 93 and an external pressure connection interface 94, the pressure sensor 93 is arranged between the battery cell 11 and the clamping plate 12, and the pressure sensor 93 and the external pressure connection interface 94 are electrically connected. When measuring the battery 1, the battery cell 11 in the battery 1 will expand due to changes in the air pressure inside the battery cell 11, thereby causing an extrusion force to appear between the clamping plate 12 that clamps the battery cell 11 and the battery cell 11. Therefore, by arranging the pressure sensor 93 between the battery cell 11 and the clamping plate 12, the extrusion force formed between the battery cell 11 and the clamping plate 12 due to the expansion of the battery cell 11 is detected. After the pressure sensor 93 measures the pressure between the battery cell 11 and the clamping plate 12, the pressure value between the battery cell 11 and the clamping plate 12 can be transmitted via an electrical signal or directly displayed on an instrument. When the pressure sensor 93 transmits the pressure value between the battery cell 11 and the clamping plate 12 via an electrical signal, an external pressure connection interface 94 is provided. The plug end of the external pressure connection interface 94 is connected to the pressure sensor 93, while the interface end of the external pressure connection interface 94 is connected to other instruments.

[0037] According to some embodiments of the present invention, the detection device 8 further includes a temperature sensor 89 . The temperature sensor 89 is attached to the battery 1 to measure the temperature of the battery 1 .
