Description

Technical Field

[0001] This utility model relates to the field of battery performance testing technology, specifically to a cylindrical battery testing assembly. Background Technology

[0002] Cylindrical batteries are based on the working principle of lithium-ion batteries, which involves charging and discharging through the repeated insertion and extraction of lithium ions between the positive and negative electrodes. Cylindrical batteries are widely used in consumer electronics and new energy fields due to their high energy density, high safety, and mature manufacturing process. During the production process, to ensure lifespan and safety, cylindrical batteries undergo internal resistance and current testing, as internal resistance is a key factor affecting battery performance. Lower internal resistance results in less heat generation under load, leading to higher efficiency and performance. Measuring current and resistance reveals the battery's health status. To enable efficient testing, an online cylindrical battery testing component was designed to continuously monitor battery performance under various operating conditions, ensuring its reliability.

[0015] It is worth noting that the voltage and current needles 7 on the needle holder 8 are arranged opposite each other, and the voltage...

[0016] The battery to be tested is placed between the current needles 7.

[0017] In addition, a travel limit block is also provided on the inner side of the slider 2.

[0018] The working principle of this specific implementation is as follows: Initially, the lifting assembly is in a raised position under the push of the cylinder. The moving block is pushed to both sides by the rolling bearings of the lifting assembly. The moving block is connected to the transmission block, the transmission block is connected to the slider, and the slider is connected to the fixed seat. When the cylindrical battery to be tested is transported to the center position of the voltage and current needles, the lifting assembly returns to its original position, and the spring guide rod pushes the fixed seat forward to complete the battery internal resistance test.

The assembly is rationally designed, including a lifting component, slider, travel limit block, fixed seat, moving seat, and spring stop, with each part working together to ensure testing accuracy and stability. The spring guide rod pushes the fixed seat forward, ensuring accurate contact between the voltage and current probes and the battery for internal resistance testing, guaranteeing reliable test results. The travel limit block prevents excessive component movement, protecting the equipment and battery from damage. This assembly is suitable for batteries of different sizes and shapes, especially cylindrical batteries. By adjusting the positions of the moving and transfer blocks, it can adapt to the testing needs of various batteries. The modular design makes each component easy to disassemble and replace, facilitating daily maintenance and troubleshooting. The cylinder-driven lifting assembly reduces energy consumption and improves testing efficiency.
