Embodiment

[0021] An intelligent charging method for a DC charging pile according to this embodiment includes the following steps,

[0022] (1) The initial state of the DC charging pile: the wiring of the charging pile is correct, when the monitoring host is started, the power indicator light is on, the touch screen displays the welcome interface, and the welcome interface displays query and charging options; click Query to enter the query interface, you can After the user swipes the card, query the account information and balance information in the user card, and display it on the touch screen.

[0023] (2) Select the charging option and enter the charging option interface; the charging option interface prompts to swipe the card in the charging pile card swiping area; if you swipe the card in the card swiping area, enter the charging mode selection interface, and the charging pile reads user information and account balance information; It also has an exit button. If you choose the exit ...

Abstract

The invention discloses an intelligent charging method of a direct current (DC) charging pile. The intelligent charging method comprises monitoring an initial state of the DC charging pile, selecting one from charging modes, displaying a charging process and determining card information and balance information. In the event of overvoltage / undervoltage, overcurrent / undercurrent, insulation faults, communication faults, card reader faults, charging gun connection faults, surge faults and other abnormal conditions during the charging process of the DC charging pile, the DC charging pile stops charging immediately and issues an abnormal signal. The intelligent charging method of the DC charging pile according to the present invention has a variety of protection functions to avoid overvoltage / undervoltage and short circuit of DC output, over-temperature and the like, and is capable of realizing the intelligent charging of the DC charging pile and ensuring the safety and stability of the working state of the DC charging pile. Compared with ordinary DC charging piles for electric vehicles, the DC charging pile has the advantages of providing the multiple charging modes, shortening the charging time and protecting storage batteries of the electric vehicles.

Description

technical field [0001] The invention relates to a charging method for an electric vehicle, in particular to an intelligent charging method for a DC charging pile. Background technique [0002] As a future development trend of electric vehicles, an important reason hindering their promotion and application is the construction of charging piles. Another important reason is the charging time of electric vehicles. There are two existing charging methods, one is an AC charging method, and the other is a DC charging method. The DC charging method can output DC400-600V high current to directly charge the car battery. Compared with the AC charging method, the DC charging method can shorten the charging time. Therefore, the DC charging method is welcomed by customers. Due to the high-voltage and high-current charging process output by the DC charging pile, the currently used charging piles often have the sintering of the main circuit control contacts. In an emergency or after the c...
