Problems solved by technology

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 circuit often appear to be sintered. In an emergency or after the charging is completed, it cannot be disconnected. The condition of the main circuit, which will damage the battery of the electric vehicle and present a dangerous

Abstract

The invention relates to a rapid charging method of a charging pile. The rapid charging method comprises the following steps of: reading card swiping information, displaying the card swiping information through a man-machine interface unit, and simultaneously reminding a user of selecting a corresponding charging mode; transmitting data to a main control module for treatment after the charging mode selection is completed, reading the card swiping information and balance information in card by the main control module, and judging the correctness of the information; transmitting the information to a direct current load contactor by the main control module if the card swiping information is correct and balance is enough; carrying charging self-inspection by the direct current load contactor, and charging an electric vehicle by the charging pile if a self-inspection result is normal; and automatically clearing and deducting corresponding amount from an integrated circuit (IC) card by the main control module according to charging amount or charging quantity after charging is completed, and printing a corresponding bill if a user requires the bill. By the rapid charging method, the safety and the stability of the working state of the charging pile are ensured, the charging time of the electric vehicle is shortened, and meanwhile, an electric vehicle storage battery is protected from being damaged through a charging protection unit

Description

technical field [0001] The invention relates to a charging pile, in particular to a fast charging method for the 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 ...
