What constitutes the smart charging pile system?

　　 The development of electric vehicles is an important direction of the national new energy strategy . Technological development of electric vehicle charging station 、 Layout and construction is an important part of the development of electric vehicles . With years of experience in power system 、 Understanding and accumulation of power electronics technology and battery energy storage technology ,V2G Electric vehicle charging station electrical system solution technology and energy storage technology . This scheme can not only provide electric vehicle battery charging and replacement , It can also be extended to distributed energy storage power stations 、 to open up 、 Interaction 、 Intelligent charge and discharge management , Make the charging station with the function of energy storage power station an important part of smart grid .

　　 Part of the
　　 The electrical system of the charging station includes the power supply system 、 Charging equipment and monitoring system .
The electrical system mainly provides power for the charging equipment , It mainly consists of primary equipment （ Including switches 、 transformer 、 Lines, etc ） And secondary equipment （ Including testing 、 Protect 、 Control device, etc ） form , Specially equipped with active filter , Eliminate harmonics , Stabilize the power grid .
　　 Charging equipment is the core part of the electrical system of the whole charging station , It is generally divided into DC charging device and AC charging device （ pile ）、 DC charging device , That is, off board charger , Realize the function of fast battery charging , Can be divided into big 、 in 、 Small 、 Company product model .
　　 AC charging device ( pile ) Provide battery slow charging function , Company product model X-AR.
Adopt off board charger V2G Imported high frequency technology IGBT The rectifier and inverter module can not only safely and quickly charge the power battery , The energy of the power battery can also be fed back to the power grid through the communication between the controller and the background system , Complete the two-way energy exchange between the grid and the battery .X-DR Type a adopts off board charger with high speed CAN Bus .
