The function of battery charge is to provide current to the external circuit for use by the device. In order to evaluate battery performance, predict battery life, optimize battery use, and improve safety, it is necessary to test the battery's charge retention ability. During the test, the battery is connected to a charging device to fully charge the battery to a specified voltage level, and then the battery is discharged to the target voltage under predetermined load conditions.

[0021] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is further described below in conjunction with the drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a battery charge retention capacity detection device, including a detection box 1, two fixed plates 2 are fixedly installed on the bottom of the inner wall of the detection box 1, two springs 3 are fixedly installed on one side of the outer walls of the two fixed plates 2, two telescopic rods 4 are fixedly installed on one side of the outer walls of the two fixed plates 2, and the outer walls of the four telescopic rods 4 are connected with the insides of the four springs 3, two springs 3 form a group, and limiting plates 5 are fixedly installed on one side of the outer walls of the two groups of springs 3, and one side of the outer walls of the two limiting plates 5 is fixedly connected to the opposite side of the outer walls of the four telescopic rods 4, two strip grooves 6 are provided at the bottom of the inner wall of the detection box 1, two sliding blocks 7 are movably embedded in the inner walls of the two strip grooves 6, and the tops of the four sliding blocks 7 are fixedly connected to the bottoms of the two limiting plates 5, and a battery body 8 is placed on the top of the inner wall of the detection box 1.

[0024] The effect achieved by the entire embodiment 1 is that the four springs 3 and the four telescopic rods 4 are squeezed simultaneously by the two limit plates 5. Since the four telescopic rods 4 are all inside the four springs 3, the linearity of the movement of the four springs 3 is improved, and the four sliding blocks 7 installed at the bottom of the two limit plates 5 are all movably embedded in the two strip grooves 6, thereby improving the stability of the movement of the two limit plates 5. Then, the charged battery is placed inside the detection box 1, and the two limit plates 5 are loosened. Under the action of the four springs 3 and the four telescopic rods 4, the two limit plates 5 limit the battery inside the detection box 1. Finally, the battery is connected to a detection device with a load condition determined in advance, and the battery is discharged to a target voltage. The battery charge retention capacity is evaluated by recording relevant data such as the battery voltage, current and time. During the entire detection process, the battery will not be hit by foreign objects, which will cause the connection between the battery and the detection device to become loose, thereby improving the accuracy of the battery charge retention capacity detection, thereby improving the use effect of the battery charge retention capacity detection device.

[0025] Embodiment 2, as Figure 2-Figure 4 As shown, a horizontal plate 9 is fixedly installed on one side of the inner wall of the detection box 1, a forward and reverse motor 10 is fixedly installed on the top of the horizontal plate 9, a threaded rod 11 is fixedly installed on one side of the outer wall of the forward and reverse motor 10, a horizontal rod 12 is fixedly installed between the inner walls of the detection box 1, a movable plate 13 is threadedly connected to the outer wall of the threaded rod 11, and the inner wall of the movable plate 13 is movably sleeved on the outer wall of the horizontal rod 12, a fan 14 is fixedly installed on one side of the outer wall of the movable plate 13, a plurality of heat dissipation holes 15 are opened on the back of the detection box 1, a dustproof net 16 is fixedly installed on the back of the detection box 1, and a single door 17 is arranged on one side of the outer wall of the detection box 1.

[0026] The effect achieved by the entire embodiment 2 is that when the detection device detects the battery with a limit, the forward and reverse motors 10 are started to drive the threaded rod 11 to rotate inside the detection box 1. Because the movable plate 13 threadedly connected to the threaded rod 11 is also movably mounted on the cross bar 12, the movable plate 13 can stably move back and forth on the threaded rod 11 and the cross bar 12, causing the fan 14 to move back and forth, thereby increasing the area for heat dissipation of the battery, ensuring that when the battery is detected, abnormal heating of the battery is prevented, thereby improving the service life of the battery. Secondly, a plurality of heat dissipation holes 15 are opened on the back of the detection box 1, and a dustproof net 16 is installed outside the heat dissipation holes 15. While ventilating, dust is prevented from entering the interior through the heat dissipation holes 15 or being adsorbed on the fan 14, which will affect the heat dissipation effect, thereby further improving the effect of battery detection.

[0027] Working principle: First, under the action of two bar-shaped grooves 6 and four sliding blocks 7, two limit plates 5 are stably moved to both sides respectively, and four springs 3 and four telescopic rods 4 are squeezed, and then the charged battery is placed on the bottom of the inner wall of the detection box 1 and between the two limit plates 5, and the two limit plates 5 are loosened. Under the action of four springs 3 and four telescopic rods 4, the battery can be limited in the detection box 1, and batteries of different sizes can be limited. Secondly, the detection device prepared in advance is connected to the limited battery, and the charge retention capacity of the battery is tested by recording the changes in relevant data such as the battery voltage, current and time. Secondly, when testing the battery, start the forward and reverse motor 10 to drive the movable plate 13 to move back and forth on the threaded rod 11 and the cross bar 12, so that the fan 14 moves back and forth in the test box 1, and the battery is cooled in multiple directions to effectively prevent the battery from abnormally heating up during operation. In general, when the detection device is used to detect the battery charge retention capacity, there will be no foreign matter colliding with it to cause the connection between the battery and the detection device to become loose, and the battery in the working state is always cooled, which ensures the service life of the battery, thereby improving the accuracy of the detection device in detecting the battery charge retention capacity.

Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields.
