Application Field
Multi-energy complementary applicationsSafer 
Multi-energy complementary application scenarios, such as large-scale charging stations or swap stations. "Optical storage and charging" or "storage and charging" integrated charging stations use clean energy to supply power, store electricity after photovoltaic power generation, photovoltaic, energy storage and charging facilities A microgrid is formed , which intelligently interacts with the public grid according to demand. The use of energy storage systems can also alleviate the impact of charging piles on the regional power grid during high-current charging. Adopt common DC bus scheme, photovoltaic, energy storage, charging pile, DCDC load, etc., to reduce ACDC conversion links. Electric vehicle energy storage V2G can be charged and discharged, realizing the bidirectional interaction between electric vehicles and grid energy. Storage and charge inspection, using to discharge new energy vehicles or battery packs, verify battery capacity, and calculate the degree of battery capacity degradation.
