1、 Introduction
With the rapid development of the new energy industry, battery sorting machines, as important equipment in the battery production process, have attracted much attention in terms of their technical principles, application cases, and market trends. This article will analyze the technical principles of battery sorting machines and explore their market development trends through practical application cases.

2、 Technical principle of battery sorting machine
The principle of battery sorting machine technology is mainly based on the combination of mechanical, electronic technology and intelligent control technology. The workflow can be roughly divided into the following steps:
1. Reception and transmission: The battery sorting machine sends the mixed batteries into the sorting area through a conveyor belt or conveying device. The conveying device can be adjusted according to the size and shape of the battery to ensure smooth entry into the sorting machine.
2. Battery type detection: The sorting machine is equipped with high-precision sensors and detection devices to identify the type of battery. Common detection methods include using characteristics such as battery volume, weight, and voltage to make judgments. Sensors emit signals and receive signals from batteries, and use these signals to make judgments and resolutions.
3. Discrimination and sorting: Based on the detection results, the sorting machine classifies batteries into different categories, usually including recyclable batteries and non recyclable batteries. Common types of recyclable batteries include nickel cadmium batteries, nickel hydrogen batteries, and lithium-ion batteries. Non recyclable batteries generally refer to batteries containing heavy metals or other harmful substances, such as lead-acid batteries.
4. Storage and processing: The sorted batteries are divided into different storage areas or processing devices according to their types. Recyclable batteries can be reused or further processed, while non recyclable batteries require specialized treatment to prevent pollution to the environment.

3、 Application Cases
Taking lithium battery sorting machines as an example, they have been widely used in the production process of electric vehicle battery packs, street lamp battery packs, automotive battery modules, balance car battery packs, and scooter battery packs. The lithium battery sorting machine sets the internal resistance and voltage values of the battery through computer software. When the battery passes through the testing area, the equipment will automatically test the internal resistance and voltage of the battery, and send the battery to the corresponding gear according to the set values. This efficient and accurate sorting method ensures the quality and stability of the battery, providing strong guarantees for the safety and reliability of the product.

4、 Market Trend Analysis
1. Market size continues to grow: With the rapid development of the new energy industry, the market demand for battery sorting machines is constantly increasing. It is expected that the global battery sorting machine market will continue to expand in the coming years.
