Charging pile module solution
Communication is installed in the electric vehicle charging pile, grid connection and communication, to provide electric car charger ac power supply device, have measurement billing function at the same time, the dc charging pile is installed outside the electric car, grid connection and communication, to provide electric vehicle power battery low power dc power supply device, dc charging pile with functions of charger, It can monitor and control the state of the charged battery, and the DC charging pile can measure the charged electricity.
CAN bus is used for data interaction between the controller of electric vehicle charger and the concentrator, and wired Internet or wireless GPRS network is used for data interaction between the concentrator and the server platform. For the sake of security, the data of electricity charging and amount are encrypted securely.
The main function of the battery management system (BMS) is to monitor the working state of the battery (battery voltage, current and temperature), predict the battery capacity (SOC) and the corresponding remaining mileage of the power battery, and manage the battery to avoid over-discharge, over-charge, over-heat and serious voltage imbalance between individual batteries. Maximize battery storage capacity and cycle life.
