Application fields
The 15KW/20KW Bidirectional ACDC Module “Photovoltaic storage charging” or “household lithium battery charging” complementary applications
1. Multi-energy complementary application scenarios, such as large charging stations or battery swapping stations, "photovoltaic storage and charging" or "storage and charging" integrated charging stations use clean energy to supply power, and store electric energy after photovoltaic power generation. Photovoltaics, energy storage and charging facilities form a microgrid, which intelligently interacts with the public grid as needed to achieve two different operating modes: grid-connected and off-grid. The use of energy storage systems can also alleviate the impact on the regional power grid when charging piles are charged with high current; it can cut peaks and fill valleys, earning the difference in electricity bills. Use a universal DC bus power supply solution, photovoltaics, energy storage, charging piles, DCDC loads, etc. to reduce ACDC conversion links, reduce investment costs, and improve system efficiency.
2. Electric vehicle energy storage V2G is a rechargeable and dischargeable bidirectional DC charging pile. Realize the two-way energy interaction and exchange between electric vehicle energy and the power grid under controlled conditions; enable electric vehicles to charge cheaply and provide low peak power. , discharge during peak hours, and car owners earn the difference in electricity bills; improve load flexibility, reduce distribution network investment, and consume clean energy; promote the development of the electric vehicle industry and reduce the area occupied by public charging facilities.
3. Storage, charging and inspection, use the discharge of new energy vehicles or battery packs to measure battery capacity and calculate the degree of battery capacity attenuation.
