Why build an integrated electric vehicle charging station with "light storage charging"?
Photovoltaic+energy storage+charging station is a green charging mode that realizes the coordinated support of new energy, energy storage, and intelligent charging. It adopts the operation strategy of "green charging, using light to support the station", which not only realizes the spontaneous self use of photovoltaic power generation and surplus electricity storage to meet the charging needs of electric vehicles, but also utilizes peak and valley electricity prices to improve energy conversion efficiency and reduce energy costs. Light storage charging, with its clean, green, and sustainable approach, improves the energy utilization structure, achieves efficient utilization and reliable power supply of new energy, and helps achieve clean electricity and green travel.
Photovoltaic system: Construct an integrated photovoltaic storage and charging power station under limited land resources, use nearby roofs and parking lot canopies to lay solar photovoltaic panels, and generate green electricity as a supplement to the charging power of new energy vehicles, maximizing the use of clean energy and achieving energy conservation and emission reduction.
Energy storage system: The energy storage system has a battery compartment and an equipment compartment. The battery system is composed of battery modules and clusters based on the minimum unit of a single energy-saving cell, and the battery capacity is configured according to the actual needs on site; Storage inverters (PCS), AC distribution cabinets, DC distribution cabinets, fire protection systems, and EMS&dynamic environmental monitoring cabinets are placed in the equipment compartment. The energy storage system is connected to the AC BUS system to improve energy utilization efficiency, optimize the configuration of electrical energy to achieve a basic balance between local energy and energy load, and flexibly interact with the public power grid according to operational needs and operate relatively independently, alleviating the impact of charging pile electricity on the power grid and solving the problem of power grid expansion in urban rapid charging infrastructure construction.
Charging station: The charging station interacts with users through scanning codes for charging, and the charging station system includes intelligent monitoring and intelligent metering. The intelligent controller of the charging station has the function of measuring and controlling the non protection of the charging station; Communication output configuration: AC intelligent energy meter is used for AC charging measurement, with complete communication function. The measurement information can be uploaded to the charging intelligent controller and network operation platform through RS485. In addition, the charging power can be adjusted, and the input and output overvoltage protection, short circuit protection, overcurrent protection, leakage protection, grounding detection, overheating and other protection functions are complete, with an IP54 protection level.
