Therefore, both vehicle manufacturers and battery manufacturers need to conduct comprehensive battery testing to truly understand and utilize batteries effectively.

[0003] When testing a battery, it is necessary to connect the positive and negative terminals and collect various parameters of the battery to understand its characteristics. The test is needed to understand important parameters such as battery capacity, internal resistance, voltage characteristics, rate characteristics, temperature characteristics, cycle life, and energy density.

[0004] However, existing technologies have some problems: existing battery testing devices are not convenient for clamping and removing batteries during use, making the battery testing process cumbersome and inconvenient. Therefore, we propose a simulated battery testing device with adjustable current and voltage. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a simulated battery testing device with adjustable current and voltage, which realizes the pushing, clamping and linkage retraction operation of the battery through a servo electric cylinder, thereby improving the convenience and stability of battery installation during testing.

The reset spring 7 is set to facilitate the resetting of the moving plate 5 when the servo cylinder 9 retracts, so that the battery can be removed under the action of the lifting block 11.

[0034] In this embodiment, preferably, the interior of the housing 2 is provided with an adjustable electronic load, which includes two fixed brackets 19 fixedly installed inside the housing 2.

[0039] The specific operation process of this utility model is as follows:

[0040] In use, the battery is placed between the two guide rods 3 and the arc-shaped long plate 18. Due to the action of the lifting block 11, one end of the battery is raised. At this time, parameters are set via the touch screen 23, and the servo cylinder 9 is activated. When the servo cylinder 9 is running, it pushes the push plate 8, enabling the push plate 8 to move. As the push plate 8 moves, the vertical rod 12 at the bottom pushes the connecting rod 10 and the lifting block 11, causing the lifting block 11 to disengage from pushing out the battery. At this time, the battery, relying on its own gravity, falls completely into the guide rods 3 and the arc-shaped long plate 18. Inside plate 18, servo cylinder 9 moves continuously, pushing plate 8 to collide with moving plate 5, causing moving plate 5 to move, so that moving plate 5 and positioning plate 4 can stably clamp the battery and maintain good contact between electrode plate 6 and the positive and negative terminals of the battery. Then, power is transmitted to adjustable electronic load through the plug cable connected to plug interface 27. The adjustable electronic load realizes constant current test voltage of battery, and displays the battery capacity, internal resistance, voltage characteristics, rate characteristics, temperature characteristics, cycle life and energy density collected by the test on touch screen 23.

[0041] After the test is completed, the servo cylinder 9 is retracted by controlling the touch screen 23, so that the pushing plate 8 stops pushing the moving plate 5, causing the battery to be released from the clamping of the positioning plate 4 and the moving plate 5. The moving plate 5 is reset and moved under the action of the reset spring 7. When the pushing plate 8 moves backward, the linkage rod 10 and the lifting block 11 move together. At this time, the lifting block 11 moves upward under the action of the limit rod 17 and the adjustment groove 16, lifting the battery to facilitate the removal of the battery and the continuous testing of the next battery.
