1. Shell: The shell of the charging pile is usually made of waterproof, dustproof and anti-corrosion materials to protect the internal electrical components from the external environment.

2. Charging interface: There are different types of charging interfaces on the charging pile, such as the international standard Type 2 interface, the Chinese national standard GB/T interface, etc., which are used to connect with the charging plug of the electric vehicle.

3. Control module: The control module of the charging pile is one of the core components, which is responsible for monitoring the charging state of the electric vehicle, controlling the output power of the charging pile and protecting the safety of the electric vehicle during the charging process.

4. Power module: The power module is the component that provides the electrical energy required for the work of the charging pile, and it can convert the alternating current of the mains power into direct current suitable for charging the electric vehicle.

5. Communication module: The charging pile is usually equipped with a communication module, which is used for data interaction and remote control with the charging management system, the user's mobile phone, etc., to achieve remote monitoring and management functions.

6. Safety protection device: In order to ensure the safety of the charging process, the charging pile is also equipped with a variety of safety protection devices, such as over-current protection, over-temperature protection, leakage protection, etc., to prevent safety accidents between the electric vehicle and the charging pile.

In general, the components of the charging pile include the shell, charging interface, control module, power module, communication module and security protection device. These components work together to provide a safe and efficient charging service for electric vehicles.
