Abstract

The invention discloses a photovoltaic charge station, comprising a photovoltaic component array used for converting solar energy to electric energy, a current-converging lightning protection box connected to the photovoltaic component array and used for converging the currents from the photovoltaic component array and performing lightning protection, a grid-connected inverter connected to the current-converging lightning protection box and used for performing current conversion, an energy storage battery used for storing the electric energy, an energy manager connected to the grid-connected inverter and the energy storage battery and used for being connected with a mains supply power grid so as to transmit the electric energy in different directions according to the different states of the electric energy and an electrical load connected to the grid-connected inverter. The photovoltaic charge station disclosed by the invention only comprises one set of current conversion system; the control system of the photovoltaic charge station is simple and convenient to implement; and the photovoltaic charge station is reasonable in design, capable of meeting the needs of different charge devices and decreasing manufacturing cost, capable of operating no matter whether the mains supply power grid exists, strong in adaptability, and convenient in market promotion.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic utilization, in particular to a photovoltaic charging station. Background technique [0002] A large amount of traditional non-renewable energy is consumed, energy problems are becoming more and more prominent, and the rapid increase in the number of cars makes the environment worsen. In view of the above problems, photovoltaic power generation and electric vehicles have become the two main directions for people to realize energy conservation and environmental protection, but there are few examples of combining the two. Generally speaking, the off-grid system is simple in design and low in cost, but its photovoltaic utilization rate is low, and a large number of batteries need to be configured for electric energy storage. At the same time, due to the uncertainty of the energy consumption of the charging system, the off-grid system has defects; and Most control systems of grid-connected syste...
