1、 Overview of electric vehicle charging stations

1. Development history and current situation of electric vehicle charging piles

In the era of the new economy, China's industrial development has been rapid, but it has brought a lot of pressure and damage to the ecological environment. With the development of China's economy and culture, strengthening environmental protection awareness and advocating energy conservation and low-carbon are inevitable trends in China's social development. Therefore, electric vehicles have emerged and gradually been promoted. Currently, electric vehicles play a crucial role in the entire automobile market in China. In the early stages of promoting and applying electric vehicles, some supporting facilities were not perfect, which greatly hindered and restricted the popularization and development of electric vehicles. With the establishment of environmental protection and sustainable development strategies, this issue has received attention and attention from relevant departments. A large amount of funds have been invested in enriching and improving the supporting facilities of electric vehicles, and certain achievements and experience have been achieved, including charging stations, charging piles, etc.

2. Methods for charging electric vehicles

The main methods of charging electric vehicles are AC charging and DC charging. DC charging is not only used for large buses, but also in many parking lots. It has both AC and DC charging stations, and DC charging stations are more suitable for fast charging of large vehicles compared to AC.

(1) Exchange charging. The use of 220V and 380V AC charging power sources has promoted the development of multifunctional on-board filtering circuits, three-phase rectifier bridges, and other charging facilities for electric vehicles. It can charge the secondary battery of electric vehicles in real time and effectively, with short time consumption and high power, and is widely used in small electric vehicles.

(2) DC charging. Using the power source on the surface of the land to charge the secondary battery (accumulator) of electric vehicles. Unlike AC charging methods, DC charging does not require secondary batteries and has a faster charging time. It is widely used in large electric vehicles and fast charging of electric vehicles.

2、 Two feasible modes of charging pile construction

1. Connection method

For the convenience of car charging, a corresponding number of AC charging piles can be built in the parking lot of electric vehicles. The 220V and 380V AC voltages used are commonly found in the automotive industry today and are relatively easy to obtain, so two forms of AC voltage can be used. Both household electric vehicles and small electric vehicles can be used, and the major feature is that electric vehicles can be charged at any time during leisure time, making it convenient to use.

2. Construction of DC charging stations

Unlike AC charging stations, DC charging stations are more suitable for charging large electric vehicles. Establishing DC charging stations in large electric vehicle parking lots can enable rapid charging of large electric vehicles. Due to the high power of DC charging stations, it is easy to cause damage to the power grid of electric vehicles, so regular maintenance and upkeep of the power grid are necessary.

3、 Ankerui Charging Station Operation and Management Platform

1. System architecture

The Acrelcloud charging station charging operation cloud platform system of Ankerui continuously collects and monitors data from charging station sites and various charging stations connected to the system through Internet of Things technology. At the same time, it provides early warnings for various faults such as over temperature protection of charging stations, input and output overvoltage and undervoltage of charging stations, insulation detection faults, etc; Then the user scans the QR code through the WeChat mini program, makes payment, and the system initiates a charging request to control the charging station corresponding to the QR code to complete the charging process of the electric vehicle.

The charging pile can be equipped with WIFI module or GPRS module to access the Internet. It can be directly connected to the cloud with encryption technology and secret key distribution technology based on TCP/IP data interaction protocol. The cloud platform includes all the functions of charging fees and charging station operation, as follows:

Resource Management: Charging Station Archive Management, Charging Station Archive Management, User Archive Management, Charging Station Operation Monitoring, Charging Station Abnormal Monitoring.

Settlement: Charging price strategy management, prepayment management, billing management, revenue and financial related statements

User Management: User Registration, User Login, User Account Management, Message Management

Charging services: searching for charging facilities, viewing charging facilities, map addressing, online self-service payment for charging, charging settlement, navigation, etc

WeChat Mini Program: Scan code for charging, bill payment and other functions

Data services: data collection, SMS reminders, data storage and parsing

Transformer monitoring: Monitor the load of charging station transformers, and each charging station is equipped with an ARCM300T wireless meter. When overloaded, the system automatically schedules and manages the charging stations. That is, when the load exceeds 50%, the system will limit the power of newly added charging stations to 50%. When the transformer load exceeds 80%, the system will not allow new charging stations to start charging until the load drops.
