The production line for AC (Alternating Current) Charging Piles is mainly divided into assembly areas, testing areas, aging areas, and sealing inspection and packaging areas, with each stage controlled independently. Automated carts are responsible for transportation to ensure production efficiency and product quality. The structure of AC charging piles is relatively simple, relying on onboard chargers to convert energy, resulting in a smooth production process.

The production line for DC (Direct Current) Charging Piles is more complex, including the precision assembly of core components such as power units, control units, metering units, and charging interfaces. The production line uses modular assembly and automated testing, with intelligent systems for monitoring to ensure the stability and safety of the charging piles. DC charging piles, with their built-in high-power charging modules, require more rigorous assembly and testing processes to meet the needs for high performance and fast charging capabilities.

Direct Current (DC) Charging Piles and Alternating Current (AC) Charging Piles differ in structure and assembly testing process flow, and the design of the automated production line will also be adjusted according to the type of charging pile. Here is the relevant information derived from the search results:
