What is the principle of the light storage charging system?
The photovoltaic energy storage and charging system has always been a popular combination in the field of new energy, and its emergence is achieved through energy storage and optimized configuration to achieve a basic balance between local energy production and energy load. Capable of independent operation and self use of surplus energy storage, it can alleviate the impact of charging pile electricity consumption on the power grid. In terms of energy consumption, the photovoltaic charging system adopts an energy storage system to charge the power battery, and uses peak and valley electricity prices to improve energy conversion efficiency and reduce electricity costs. In addition, the battery energy storage system is used to absorb low power and support fast charging loads during peak hours. At the same time, the photovoltaic power generation system serves as a supplement, effectively reducing the peak load of the charging station on the power grid, improving the operational efficiency of the system, and providing auxiliary service functions for the power grid.
Under limited land resources, a solar energy storage and charging system charging station will be constructed, using rooftop photovoltaics and rooftop photovoltaics in parking lots. Multiple photovoltaic modules are connected to the photovoltaic DC combiner box and connected to the grid through photovoltaic inverters. The off grid photovoltaic power generation system effectively solves the problem of energy star conversion during the generation, discharge, power supply, and transmission of solar photovoltaic modules, ensuring the reliability, efficiency, and safety of the entire photovoltaic storage and charging system, and enabling stable operation of the power station.
The energy storage system is equipped with a battery room and an equipment room. The electrical grounding system is composed of individual energy-saving batteries as small units, forming battery modules and battery packs. The capacity is configured according to the actual needs on site; The energy storage converter (PCS), AC distribution cabinet, DC distribution cabinet, fire protection system, and dynamic ring monitoring cabinet are placed in the equipment warehouse. The energy storage system is connected to the AC bus system to improve energy efficiency and balance the production and supply of the power system.
The charging station of the light storage charging system interacts with users through scanning codes for charging, and the system includes temporary energy monitoring and measurement. The intelligent controller of the charging station has the functions of measuring, controlling, and protecting the charging station, such as detecting the operating status, fault status, and linkage control during the charging and discharging process; The communication output is equipped with an intelligent AC electricity meter for AC charging measurement, which has complete communication functions. 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. The transmission shaft has complete protection functions for input and output overvoltage, undervoltage, short circuit, overcurrent, leakage, grounding detection, overheating, etc., with a protection level of IP54.
Today, under the dual crisis of energy and ecology, the "dual carbon" goal has formed a high consensus worldwide, bringing unprecedented development opportunities for new energy sources including photovoltaics. It is necessary to understand the photovoltaic storage and charging system. The dual carbon strategy implemented by it will inject new vitality into various industries, constantly change the competitive landscape of the industry, and also stimulate the rise of emerging industries such as new energy, photovoltaics, and energy storage.
