Application of Industrial Panel PC in Charging Piles of Electric Vehicle Charging Station

With the widespread application of industrial panel PC technology in the electric vehicle industry, electric vehicles have been close to or even better than traditional fuel vehicles in terms of performance and economy, and have been rapidly promoted and applied globally in recent years. Being clean, environmentally friendly and energy-saving, the electric vehicle has become a hot spot and inevitable trend in the development of the world's automobile industry. The charging system supported by the industrial panel PC provides energy supply for the operation of electric vehicles. It is an important basic support system for electric vehicles and an important link in the commercialization and industrialization of electric vehicles.

1. System requirements for industrial panel PCs for charging piles of electric vehicle charging stations

Most of the electric vehicle charging stations are set up beside outdoor roads, and the environment characteristics of high temperature, dust and humidity need to be considered, and the environment adaptability is strong. Electric vehicle charging stations generally have a large number of outlets and are scattered, and maintenance costs are high. Therefore, industrial panel PCs are required to have a high mean time for operation with no failures. It provides outdoor visual interface for outdoor users and operators, with wide viewing angle characteristics. With FLASH or CF card storage media, you can install the operating system and store advertising content. It can realize the operation of the car owner's free team charging terminal, which requires a high-brightness touch display monitor.

2. System requirements for charging piles of electric vehicle charging stations

The general intelligent electric vehicle system will include electric vehicle charging piles, concentrators, battery management system (BMS), and charging management service platform. Among them, the terminal controller of the electric vehicle charging pile can be completed by the corresponding industrial all-in-one pc. The user can swipe the card for user authentication, balance query, billing query and other functions, and it can also provide a voice output interface to achieve voice interaction. The user can select 4 charging modes according to the instructions of the touch screen: including charging on time, charging according to power, automatic charging, charging according to mileage, etc.

The main function of the battery management system (BMS) is to monitor the working status of the battery (the voltage, current and temperature of the battery), predict the battery capacity (SOC) of the power battery and the corresponding remaining mileage, and perform lithium battery management to avoid excessive discharging, overcharging, overheating and serious voltage imbalances between single cells can make full use of the storage capacity and cycle life of lithium batteries.

The charging service management platform has three main functions: charging management, charging operation, and comprehensive inquiry. Charging management conducts centralized management of the basic data involved in the system, such as electric vehicle information, lithium battery information, user card information, and charging pile information; charging operation mainly performs charging management for user charging; comprehensive query refers to management and operation comprehensive analysis and query of data.
