The invention discloses an electric vehicle intelligent charging station, which includes a charger and a charging terminal. The charger includes an AC power distribution module, a rectification module, a switch matrix and a power controller. The AC power distribution module supplies power to the charger. Each charger includes several rectification modules, several rectification modules are divided into several groups of power units, several groups of power units are connected to several DC output circuits through switch matrix control, and each DC output circuit is connected to a corresponding charging terminal, the switch According to the control instructions of the power controller, the matrix switches each group of power units in several DC output circuits. The invention can realize the reasonable allocation of the power distribution capacity of the power grid, and guarantee the orderly power supply of residential quarters and charging stations.
Description
technical field [0001] The invention relates to electric power engineering technology, in particular to a charging system for an electric vehicle charging station. Background technique [0002] With the rapid development of electric vehicles, the number of people using electric vehicles is increasing year by year, and the charging demand of users is very urgent. Increasing the construction of charging facilities can alleviate the tight charging demand. At present, the conventional electric vehicle smart charging station has a single charging strategy, which cannot meet the charging needs in different situations, and is likely to cause overload, which will seriously affect the load and voltage of the distribution network, and even affect the daily life of residents. Electricity and industrial production electricity. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a charging system for an electric vehicle intellig...
