Alternating current charging pile control system

Abstract

The invention discloses an alternating current charging pile control system. The alternating current charging pile control system comprises a main controller, a communication managing module, a billing module and an automatic protection module. The communication managing module comprises a DGUS screen, a loudspeaker, a printer, a charging state indicator and an output socket. The billing module comprises a managing host, an IC card reader-writer, an IC card, an antenna and a multifunctional power meter. The automatic protection module comprises a one-way electric leakage protector, an anti-thunder, a safety relay, an alternating current contactor and a sudden stop switch. According to the alternating current charging pile control system, user account information is stored into the main controller and monitored and updated in real time, a user can pull up a cable at any time in the charging process, charging is automatically quitted, and flexibility is improved; three-level redundancy is designed, accurate coefficients of fault detecting and fault protecting are increased, and misfunction and no-action caused by device aging, the weather and the like are avoided; a networking billing unit and a stand-alone billing unit are arranged, information such as the user account balance can be temporarily stored under the situation of networking failures or power grid failures, and the billing accuracy and safety are guaranteed.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to an AC charging pile control system. Background technique [0002] The function of the AC charging pile is similar to the fuel dispenser in the gas station. It can be fixed on the ground and installed in public buildings (such as public buildings, shopping malls and public parking lots, etc.), residential parking lots or charging stations. It is mainly used to provide vehicle-mounted The electric vehicle of the charger is used, the input end of the AC charging pile is directly connected with the AC power grid, and the output end is equipped with a charging plug for charging the electric vehicle. On the human-computer interaction interface provided by the charging pile, corresponding operations such as charging method, charging time and cost data printing can be performed, and the display screen of the charging pile can display data such as charging amount, cost and charging...

AI Technical Summary

Problems solved by technology

[0003] At present, the popular AC charging piles on the market are all equipped with card-swiping interfaces, which support common card-swiping methods such as RFID cards and IC cards, and can be configured with printers to provide ticket printing functions. Trouble, storing consumption data in the IC card, there is a hidden danger of the IC card being cracked, and the existing charging pile is not equipped with a backup system. When the equipment is aging or the weather is bad, the AC charging pile will malfunction or not operate.
