The overall system consists of four parts: electric vehicle charging pile, concentrator, battery management system (BMS), and charging management service platform.
The control circuit of the electric vehicle charging pile (plug) is mainly completed by the embedded ARM processor. Users can swipe their cards to perform user authentication, balance query, billing query and other functions. It can also provide a voice output interface to achieve voice interaction.
Users can choose 4 charging modes according to the instructions on the LCD screen: including charging by time, charging by power, automatic full charge, charging by mileage, etc.
The electric vehicle charger controller and the concentrator use the CAN bus for data exchange, and the concentrator and the server platform use the wired Internet or wireless GPRS network for data exchange. For safety reasons, the electricity billing and amount data are securely encrypted.
The main functions of the battery management system (BMS) are to monitor the working status of the battery (battery voltage, current and temperature), predict the battery capacity (SOC) of the power battery and the corresponding remaining mileage, and manage the battery to avoid over-discharge, over-charge, overheating and serious voltage imbalance between single cells, so as to maximize the use of battery storage capacity and cycle life.-1057096.jpg "新能源 (15).jpg")
