Zusammenfassung:According to the light storage and charging efficient charging system for the electric automobile in the weak light environment, a steel structure shed is built in a parking lot, photovoltaic power generation systems are built on the top of the steel structure shed and on the roof of a building nearby, and generated power is preferentially supplied to the electric automobile for use through an electric automobile charging pile; the residual electric quantity can be stored in an energy storage system built by using an ex-service battery of the electric vehicle, when photovoltaic power is insufficient, the energy storage system serves as an adjusting power supply to supply power to the electric vehicle, and if the power still has a gap, the power is obtained from a power grid to supply power to the electric vehicle. And green travel is realized. The energy storage system can charge in the valley period and discharge in the peak period to realize peak-valley arbitrage, and can also form an adjustable resource to
