The charging pile system is a core facility that provides energy supply to electric vehicles, consisting of charging equipment, distribution systems, billing units, and management platforms. The integration of charging piles with energy storage systems is an efficient and flexible energy solution. By coordinating with energy storage batteries (such as lithium or sodium batteries), the charging pile system can achieve peak shaving, dynamic capacity expansion, and emergency power supply. This solution is suitable for areas with weak power grids, photovoltaic-storage-charging integrated stations, and V2G (Vehicle-to-Grid) scenarios, promoting the development of sustainable transportation energy.
