The power supply system mainly supplies power for charging equipment, which is mainly composed of primary equipment (including switches, transformers, lines, etc.). ) and secondary equipment (including detection, protection and control devices, etc. ). It is specially equipped with active filtering devices to eliminate harmonics and stabilize the power grid.
Automobile charging system is the core part of the electrical system of the whole charging station. Generally divided into DC charging device and AC charging device (pile). DC charging device, that is, off-board charger, realizes the function of fast charging of batteries, which can be divided into three types according to power output: large, medium and small. The company's product model is X-DR, and the AC charging device (pile) provides the function of battery slow charging. The company's product model is X-AR.
X-DR off-board charger adopts V2G technology. The imported high-frequency IGBT rectifier inverter module can not only charge the power battery safely and quickly, but also feed back the energy of the power battery to the power grid through the communication between the controller and the background system, thus completing the two-way energy exchange between the power grid and the battery. X-DR off-board charger adopts high-speed CAN bus to ensure fast and reliable communication connection. Specific schematic diagram and physical diagram are as follows:
