Abstract

The invention relates to a direct-current charging pile, which comprises a charging power supply, an intelligent control module, a direct-current charger, a master control module and a direct-current load contactor, wherein the intelligent control module comprises a central control unit, a charging unit, a card-swiping unit, an energy dispatching unit, a man-machine interface unit, a low-voltage auxiliary unit, a charging protection unit and at least two charging ports; the charging unit, the card-swiping unit, the energy dispatching unit, the man-machine interface unit and the charging protection unit are in interactive connection with the central control unit; an input end of the low-voltage auxiliary unit is connected with an output end of the central control unit; the output end of the low-voltage auxiliary unit is connected with the input end of the charging port I; the output end of the charging protection unit is connected with the input end of the charging port II; the output ends of the charging port I, the charging port II and the central control unit are respectively connected with the input end of the direct-current charger through communication units; and the output end of the direct-current charger is in interactive connection with the master control module.

Description

technical field [0001] The invention relates to a charging pile, in particular to a DC charging pile. Background technique [0002] The vigorous development and use of electric vehicles will become a future trend, and an important reason hindering its promotion and application is the construction of charging piles. Another reason is the charging time of electric vehicles. There are two types of charging piles, one is AC charging piles and the other is DC charging piles. The AC charging pile outputs 220V AC to charge the battery through the on-board charger. The DC charging pile can output DC400V high current to charge the battery directly. The charging time of DC charging piles is much shorter than that of AC charging piles. Therefore, DC charging piles are welcomed by many customers. Due to the high voltage and high current output of the DC charging pile currently used, the device that controls the main circuit consumes a lot, and the control contacts of the main circu...
