[Application Fields]
Applications of "PV energy storage and charging" or "energy storage and charging" in complementary multiple energy scenarios:
In scenarios such as large-scale charging stations or battery swapping stations, integrated "photovoltaic energy storage and charging" or "energy storage and charging" stations utilize clean energy sources. The generated solar energy is stored in the energy storage system, forming a microgrid that integrates photovoltaics, energy storage, and charging facilities. This microgrid can intelligently interact with the grid according to demand, enabling both grid-connected and off-grid operation modes. The use of energy storage systems can also mitigate the impact on the regional power grid during high-current charging of electric vehicles. Additionally, it can help with peak shaving and valley filling, taking advantage of price differences in electricity tariffs.
By adopting a shared DC bus power supply scheme, including photovoltaics, energy storage, charging stations, DC/DC loads, etc., the number of AC/DC conversion stages is reduced, resulting in lower investment costs and improved system efficiency.
Vehicle-to-Grid (V2G) technology, which utilizes bidirectional DC charging stations, allows electric vehicles to not only charge but also discharge, enabling controlled two-way interaction and energy exchange between electric vehicles and the grid. This enables electric vehicle owners to charge their vehicles with cheaper or off-peak electricity and discharge during peak hours to earn the price difference. V2G also enhances load flexibility, reduces distribution network investments, facilitates the integration of clean energy sources, and promotes the development of the electric vehicle industry while reducing the footprint of public charging facilities.
