The types of DC charging piles mainly include split type and integrated type. The integrated DC charging pile integrates all components in a cabinet, with a compact design, suitable for fixed installation scenarios. The split DC charging pile consists of a rectifier cabinet and a DC charging pile, which are connected by cables and have higher flexibility and scalability. It is suitable for places where multiple charging guns are required.
Internal structure
The internal structure of the DC charging pile includes the following main parts:
External shell body: protects internal electronic components and ensures safe use. It is usually durable and waterproof and dustproof.
Charging gun: responsible for transmitting electrical energy to the battery of the electric vehicle. It is designed with 9 holes and has safety functions such as overcurrent protection and short circuit protection.
Main control system: monitors and controls the entire charging process, obtains charging status, fault diagnosis and remote control information.
Charging module: efficiently converts AC power into DC power, which directly affects the charging speed and efficiency.
Power supply part: includes power switch, power manager and fuse to ensure the operation quality and safety of the charging pile.
