The input voltage of the ground DC charging pile adopts the three-phase and five-wire system, that is, the three-phase AC power supply system contains five lines, which are three phase lines (three phases A, B and C), a neutral line (N line) and a ground line (PE line) respectively.

The input voltage of portable DC charging pile adopts single-phase three-wire system, which means that there are three lines in the single-phase AC power supply system, which are phase line (fire line), neutral line (zero line) and ground line (protection ground line).

Product overview of DC charging pile Basic Functions Fast Charging DC charging piles can provide high charging power, allowing electric vehicles to be fully charged in a short amount of time. Intelligent Control Equipped with intelligent charging control functions, these chargers can automatically adjust charging parameters based on the battery’s status, ensuring battery safety and extending its lifespan. Additionally, charging…

DC charging piles are essential equipment that provides fast charging services for electric vehicles. Their working principle involves several key stages. Below, we will outline the working principle of DC charging piles through five aspects: power supply, rectification, control system, charging process, and safety protection.

At present, the charging methods of electric vehicles are mainly divided into DC charging and AC charging. The advantages of AC on-board charging are that it saves the cost of charging pile, is more flexible and convenient, but has low charging power, and increases the weight and design complexity of the body. Dc charging can output more power current, so as to achieve super fast charging.

This paper will introduce the main components of DC charging pile, including shell or exterior structure, charging module, control module, billing communication unit, charging gun and other components.
