Description

Technical Field

[0001] This application relates to the field of lead-acid battery technology, and in particular to a lead-acid battery pack voltage detection device. Background Technology

[0002] Besides lithium batteries, lead-acid batteries are also a very important type of rechargeable battery. A lead-acid battery is a battery in which the electrodes are mainly made of lead and its oxides, and the electrolyte is sulfuric acid solution. In the discharged state, the main component of the positive electrode is lead dioxide and the main component of the negative electrode is lead. In the charged state, the main components of the positive and negative electrodes are lead sulfate.

[0003] Existing patent publication number CN221746246U describes a battery voltage detection auxiliary device, relating to the field of battery testing equipment. It includes a base, an operating platform, and two clamping components. The operating platform is fixedly connected to the top of the base via several buffer components, and the two clamping components are fixedly connected to the top of the operating platform. After placing the battery on the mounting bracket using the clamping components, the pressing block can be released. At this point, the first spring, having lost the pressing force applied by the pressing block, will cause the sliding block to slide within the slide rail. Simultaneously, the battery returns to the compression auxiliary fixing mechanism, applying a compressive force to the auxiliary fixing mechanism, thereby squeezing the auxiliary fixing mechanism to both sides and clamping and positioning the battery. This device solves the problem of inaccurate clamping plate position caused by manufacturing and assembly errors of gears and racks, and reduces the impact on battery positioning accuracy. However, the aforementioned patent still has certain drawbacks. While it uses the spring's rebound force to position the battery, which provides a certain clamping force, this force is unstable, reducing the quality of the detection. Therefore, we propose a lead-acid battery pack voltage detection device to solve the above problems. Utility Model Content
