[0002] Solid-state batteries have improved safety due to their structural advantages, thereby increasing their adaptability to a wide range of usage scenarios and expanding the scope of application of batteries.

[0003] The patent with the patent announcement number CN217768496U relates to the technical field of battery performance testing devices, including: a frame, a sealing assembly, a positive electrode, a positive electrode pressure sensor, a negative electrode and a negative electrode pressure sensor. The sealing assembly is provided with positive and negative electrode connection holes at both ends. Before testing, the solid-state battery to be tested needs to be placed in the sealing assembly, and the solid-state battery to be tested is located between the positive electrode and the negative electrode. The positive and negative electrode pressure sensors are in indirect or direct contact with the positive and negative electrodes. After the assembly is completed, the data measured by the positive electrode pressure sensor and the negative electrode pressure sensor are initial values. During the charging and discharging process of the solid-state battery to be tested, the positive electrode pressure sensor can detect the stress changes of the positive electrode material of the solid-state battery to be tested, and the negative electrode pressure sensor can detect the stress changes of the negative electrode material of the solid-state battery to be tested. By detecting the stress changes of the positive electrode material and the negative electrode material of the solid-state battery during charging and discharging, it is beneficial to improve the safety of the solid-state battery.

[0004] The above patent is beneficial to improving the safety of solid-state batteries by detecting the stress changes of the positive and negative electrode materials during charging and discharging of solid-state batteries. However, when the battery is charged and tested, the battery may shift so that the plug cannot be accurately inserted into the battery charging port. The shift may cause the position of the battery in the test equipment to change, thereby affecting the measurement accuracy. Summary of the invention

[0007] According to the above technical solution, a No. 1 spring is provided between the push plate and the clamping plate. The No. 1 spring is provided to avoid damaging the battery when clamping the battery. The clamping plate will move toward the push plate to accumulate force for the No. 1 spring.

The plug is then taken out and replaced with a plug that matches the model. The plug can be quickly replaced, which can effectively improve the speed at which the staff replaces the plug, and can effectively improve the work efficiency of the staff.

[0009] According to the above technical solution, a No. 4 spring is provided between the clamping plate and the square plate.

The fixed block is fixedly installed on the side of the cover plate close to the sliding groove. The movement of the telescopic rod will pull the slide plate to slide downward, and the sliding of the slide plate will lose contact with the fixed block, then the limit of the cover plate will be released, and the cover plate will be driven by the No. 1 torsion spring to rotate to seal the placement frame. When the cover plate rotates, it will drive the fire extinguishing device to move, so as to avoid the battery spontaneous combustion caused by the aging of the battery itself during the charging test, which will affect the outside. At this time, the cover plate can effectively prevent the spread of fire.

[0014] The present invention provides a solid-state battery performance testing device, which has the following beneficial effects: (1) In the present invention, the extension of the electric push rod will push the push plate to move in the direction of the placement table, and the movement of the push plate will push the clamping plate to move in the direction of the placement table, so that the clamping plate will fix the battery to prevent the battery from shifting during the battery charging test, which may cause the power plug to be unable to be properly inserted into the battery. The shift may cause the position of the battery in the test equipment to change, thereby affecting the measurement accuracy. The sliding of the sliding rod will push the rotating rod to rotate, and the rotation of the rotating rod will push the sliding plate to slide. The sliding of the sliding plate will drive the push rod to move in the direction of the battery to align the battery, thereby preventing the battery charging port from being aligned with the power cord during the battery charging test, which may cause the power plug to be unable to be properly inserted into the battery.

[0015] (2) In the invention, the No. 2 hydraulic rod will push the square plate to move, and the movement of the square plate will drive the power cord plug to move. The plug is inserted into the battery to charge the battery, which can effectively ensure that the battery is detected only after it is fixed, avoiding the battery from shifting when the plug is inserted into the battery, resulting in the power plug not being able to be properly inserted into the battery. When the plug does not match the battery model to be charged, the rotating pin is rotated to release the limit on the clamping plate, and the sliding clamping plate releases the clamping of the plug. The plug is then taken out and replaced with a plug that matches the model. The plug can be quickly replaced, which can effectively improve the speed at which the staff can replace the plug, and can effectively improve the work efficiency of the staff.

[0016] (3) In the present invention, the movement of the telescopic rod will pull the slide plate to slide downward. The slide plate will lose contact with the fixed block, and the limit of the cover plate will be released. The cover plate will be driven by the No. 1 torsion spring to rotate and seal the placement frame. When the cover plate rotates, it will drive the fire extinguishing device to move, so as to avoid the battery self-ignition caused by the aging of the battery itself during the charging test, which will affect the outside. At this time, the cover plate can effectively block the spread of fire, and the fire extinguishing device will release carbon dioxide to extinguish the fire when it detects high temperature. When the fixed key slides, the pin will contact the inner wall of the sliding groove, limiting the fixed key, so as to avoid the staff taking it out when the battery is tested, so that the battery is not fully tested. At the same time, it also avoids the case where the battery is opened before the fire is completely extinguished when the battery catches fire, which promotes the spread of fire.
