The concept of the charging post is like the data line of our mobile phone. Charging piles can be divided into AC charging piles and DC charging piles. Before purchasing new energy charging piles, we should have an overall concept of charging pile energy and know its classification and composition. DC charging pile is mainly composed of four parts: charging pile, concentrator, battery management system (BMS), and charging management service platform. below New energy vehicle maintenance Xiao Bian will introduce each component of the DC charging pile to you in detail. Let's have a look!

1. Charging post

There are multiple styles and models of charging posts, which are different in power supply mode and appearance. AC charging pile is applicable to public parking lots such as airports, docks, stations, shopping malls or public parking on streets. It has wall mounted, simple and other shapes, which is convenient for layout and scene design, and can provide AC power for electric vehicles with on-board chargers.

The DC charging pile is large, generally in the structure of a split charger, which is placed in the electrical room, and the DC charging terminal is placed on the charging parking space. DC charging pile is applicable to charging station, power exchange station, vehicle charging, bus station parking lot, etc.

2. Concentrator

Electric vehicle charging pile The control circuit of is operated through the embedded ARM processor. The electric vehicle owner can swipe the card by himself. The balance query, billing query and other functions can be carried out through user identification. It can provide voice output interface and achieve voice interaction. The user can select four charging modes according to the indication of the LCD screen: charging on time, charging according to the quantity of electricity, automatic charging, charging according to the mileage, etc.

3. Battery management system (BMS)

The main function of the battery management system (BMS) is to monitor the working state of the battery (voltage, current and temperature of the battery), predict the battery capacity (SOC) of the power battery and the corresponding remaining mileage, manage the battery to avoid over discharge, over charge, overheating and serious voltage imbalance between individual batteries, and utilize the battery storage capacity and cycle life.

4. DC charging pile management service platform

The charging management service platform can provide charging management, charging operation and comprehensive query services. Charging management conducts centralized management on the basic data involved in the system, including user card information, electric vehicle information, charging pile information, battery information, etc. Charging operation can calculate fees through user charging, and collect the amount in the deduction card through the platform. The customer information and transaction information will be treated confidentially.

The composition of the DC charging post is introduced above, hoping to be helpful to everyone.
