"Optical storage and charging" has always been a popular combination in the new energy industry. The integrated solution of optical storage and charging realizes the basic balance between local energy production and energy load through energy storage and optimal configuration.
It can operate independently, "self use and residual power storage", which alleviates the impact of charging pile power consumption on the power grid; In terms of energy consumption, the energy storage system is used to charge the power battery, and the peak valley electricity price is used to improve the energy conversion efficiency and reduce the electricity cost; The battery energy storage system is used to absorb the low ebb electricity and support the fast charging load in the peak period; At the same time, the photovoltaic power generation system is used to supplement, effectively reduce the grid load in the peak period of the charging station, improve the system operation efficiency, and provide auxiliary services for the grid.
PV system
Under the limited land resources, the integrated power station of optical storage and charging will be built, and the nearby roof photovoltaic and parking lot canopy photovoltaic will be used. Several photovoltaic modules are connected to the photovoltaic DC combiner box, connected to the power grid through the photovoltaic inverter, and the off grid photovoltaic power generation system and off grid photovoltaic power generation system effectively solve the problems of power generation, discharge, power supply and energy conversion in the transmission process of solar photovoltaic modules, ensure the reliability, efficiency and safety of the power generation of the entire system, and enable the power generation of the power station to operate stably.
Energy storage system
The energy storage system has a battery compartment and an equipment compartment. The battery system uses a single cell as the minimum unit to form battery modules and battery clusters. The battery capacity is configured according to the actual needs of the site; Energy storage converter (PCS), AC power distribution cabinet, DC power distribution cabinet, fire protection system and EMS&dynamic ring monitoring cabinet are placed in the equipment warehouse. The energy storage system is connected to the AC BUS system to improve the energy utilization efficiency and balance the production and supply of the power system.
Charging pile
The charging pile interacts with the user through code scanning charging. The charging pile system includes intelligent monitoring and intelligent metering. The intelligent controller of the charging pile has measurement, control and protection functions for the charging pile, such as operation state detection, fault state detection and linkage control of the charging and discharging process; The AC output is configured with AC intelligent electric energy meter for AC charging metering. It has perfect communication function and can upload metering information to the charging intelligent controller and network operation platform through RS485. In addition, the charging power is adjustable, and the input and output overvoltage and undervoltage protection, short circuit protection, overcurrent protection, leakage protection, grounding detection, over temperature and other protection functions are complete, with IP54 protection level.
