Embodiment Construction

[0049] refer to figure 1As shown in the figure, the substation adopts a 10kV three-winding transformer, of which the high-voltage side is connected to the 10kV power grid to supply power for local loads; the low-voltage side of 0.4kV is connected to an electric vehicle intelligent charging station, which directly serves the electric vehicle charging equipment, and at the same time realizes electricity supply for residential areas. Among them, the electric vehicle intelligent charging station includes several chargers, and each charger is connected to 6 charging terminals. The charger adopts an outdoor design, the power units are centrally arranged inside the charger, the charging terminal is arranged at one end of the parking space, and the charging terminal adopts a single-gun design. , configure the man-machine interface and charging gun. In addition, there is also a charging monitoring system. One 20A power supply is introduced as a charging monitoring power supply. Each su...

Abstract

The invention discloses an electric vehicle smart charging station, which includes a charger and a charging terminal. The charger includes an AC power distribution module, a rectifier module, a switch matrix and a power controller. The AC power distribution module supplies power to the charger. Each charger contains several rectifier modules. The several rectifier modules are divided into several groups of power units. The several groups of power units are connected to several DC output circuits through switch matrix control. Each DC output circuit is connected to a charging terminal. The switch The matrix switches each group of power units in several DC output loops according to the control instructions of the power controller. The invention can realize reasonable distribution of power distribution capacity of the power grid and ensure orderly power supply to residential areas and charging stations.

Description

Technical field [0001] The invention relates to electric power engineering technology, and in particular to an electric vehicle DC 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 users' charging needs are very urgent. However, during the planning and design of the original distribution substation, electric vehicle charging facilities were not included in the design capacity of the distribution substation. The existing distribution capacity of the distribution substation cannot meet the rapidly growing charging demand for electric vehicle charging facilities. In addition, it is currently difficult to acquire land for the construction of charging facilities. In order to comprehensively consider regional power distribution capacity and charging needs, the construction of electric vehicle charging stations based on the integration of distribution, distrib...
