With the booming of new energy vehicles, the construction of charging piles is increasingly booming, and the capacity of the power grid is limited. At the same time, the policy direction of carbon peak and carbon neutrality provides an opportunity for the development of integrated optical storage and charging stations. The photovoltaic storage and charging station use photovoltaic power generation to store electric energy through energy storage batteries. Photovoltaic, energy storage and charging facilities form a micro-grid, which intelligently interacts with the public power grid according to the demand. It can eﬀectively achieve peak clipping and valley leveling, not only alleviating the impact of charging piles on the regional power grid when charging with large current, but also providing green energy for electric vehicles and eﬀectively improving the operating eﬃciency of the system. Aiming at the market of optical storage and charging, our company specially introduced special charging pile for optical storage and charging, which can directly charge DC electricity of photovoltaic into electric vehicles or energy storage batteries, or directly charge DC electricity of energy storage batteries into electric vehicles, eliminating the transfer of inverter, improving the overall eﬃciency and reducing the cost of the charging station.
