The invention discloses a photovoltaic charging system which includes a solar cell module, a storage battery module, a first DC (direct current) / DC circuit, a first DC / AC (alternating current) circuit, a second DC / AC circuit and a second DC / DC circuit, wherein the first DC / DC circuit is used for utilizing a DC output by the solar cell module to charge the storage battery module, the first DC / AC circuit is used for converting a DC into an AC and transmitting the AC to AC electric equipment and / or a grid, the second DC / AC circuit is used for converting a DC output by the storage battery module into an AC and transmitting the AC to the AC electric equipment and / or the grid, and the second DC / DC circuit is used for converting a DC output by the storage battery module in a DC mode and transmitting the DC to DC electric equipment. The invention further discloses a charging station. The photovoltaic charging system and the charging station utilize solar energy and secondary batteries, not only provide a convenient charging mode for the DC electric equipment, but also fully utilize stored energy of the secondary batteries.
Description
technical field [0001] The invention relates to a photovoltaic charging system and a charging station, in particular to a photovoltaic charging system and a charging station for cascade utilization of power batteries. Background technique [0002] The national "Twelfth Five-Year Plan" takes new energy pure electric vehicles as the development direction, and the development of new energy vehicles shows a good momentum. With the rapid development of electric vehicles, charging stations matching electric vehicles are becoming a new industry. my country's power resources are in short supply, so it is necessary to find a new solution to the charging of electric vehicles. [0003] Due to the shortage of power resources, the cascade utilization of power batteries will also be an important link to improve the comprehensive utilization of energy. According to the relevant regulations of the country, after the actual capacity of the electric vehicle power storage battery declines to ...
