Abstract

The invention discloses a charging device, which is applied to a charging system adopting a photovoltaic module and a power grid for combined power supply and comprises a photovoltaic charging module, a direct current charging module, a control module and a power distribution module. Charging energy of the charging device comes from a photovoltaic module and a power grid, and charging currents provided by the photovoltaic module and the power grid for to-be-charged equipment are controllable, so that the charging currents provided by the photovoltaic module and the power grid for the to-be-charged equipment are reasonably regulated and controlled according to the charging current requirement of the to-be-charged equipment, therefore, the required electric energy is provided for the to-be-charged equipment, the total charging current fluctuation of the to-be-charged equipment is small, and the charging reliability is high. The invention further discloses a charging method and system which have the same beneficial effects as the charging device.

Description

technical field [0001] The invention relates to the field of electric vehicle charging, in particular to a charging device, method and system. Background technique [0002] Charging stations for electric vehicles are usually powered by the grid. The charging principle is: convert the alternating current output from the grid into direct current, and use the converted direct current to charge the electric vehicle. However, under the single grid power supply mode, the charging station needs to pay a higher electricity fee to the grid supplier, resulting in higher operating costs for the charging station. [0003] With the development of photovoltaic systems, most charging stations begin to use the combination of photovoltaic modules and grids for power supply. The charging principle is: convert the alternating current output from the grid into direct current, and combine the converted direct current with the direct current output from photovoltaic modules to charge electric veh...
