Internal structure of energy storage vehicle charging pile

An EV charger or charging pile is a unit intended for supplying electric energy to an electric vehicle that requires charging in order to increase its stored energy. They act as intermediaries between the power grid and an electric vehicle (EV), controlling the current and voltage supply to ensure that charging is done efficiently and safely.

A charging pile comprises several components which are crucial for its operational functionality and security features: Power Supply Module – Converts and stabilizes the energy from the grid. Charge Controller – Smartly operates the voltage, current, and communication functions between the vehicle and the charging pile.

The effectiveness of PV energy sources is also substantially grown because an abundant charging network encourages the application of clean energy in place for fossil fuels, contributing to lower carbon emissions around the world. The installation of a private charging pile is economically beneficial to EV owners.

Although “charging pile” and “charging station” are occasionally used interchangeably, they describe different ideas. A charging pile is the basic component of an electric power infrastructure that allows electricity to flow to the vehicle.

Information display screen Some charging piles are equipped with information display screens, which can display information such as voltage, current, real-time power, temperature, charging time, etc. Some can also display the working status of each phase of the three-phase charging pile.

From the external structure, the charging pile is clearly divided into components such as the pile body, cable, and charging gun head. At first glance, it seems that the charging pile performs the charging work, but for the AC charging pile, the real charging process is completed by the on-board charger (OBC) built into the car.
