Charging bow type electric car charging system

Abstract

A charging bow type electric car charging system comprises a station part and a vehicle-mounting part; the station part comprises a rectifying cabinet, a charging frame, a charging bow, and an interface monitoring module; the charging frame is connected with the charging bow through a charging bow walking mechanism; a rectifying module, a power distribution module, and a charging monitoring moduleare arranged in the rectifying cabinet; the interface monitoring module comprises a first single chip, and the first single chip is connected with the charging bow control module through a first communication converting module, and the charging bow control module controls the charging bow walking mechanism; the first single chip is further connected with a wireless communication module; the vehicle-mounting part comprises a second single chip, a second communication converting module and a vehicle-mounted wireless module; the vehicle-mounted wireless module is in wireless communication with the wireless communication module. The invention provides a safe and intelligent charging bow type electric car charging system, and matches with a declined charging bow; thus the charging system savescost and is convenient to use.

Description

technical field [0001] The invention belongs to the field of DC charging systems for electric vehicles, in particular to a charging bow type electric vehicle charging system. Background technique [0002] With the popularity of new energy electric vehicles, the market's demand for large-capacity batteries and high-current fast charging is becoming more and more urgent. However, the current charging equipment is limited by the charging interface, and the maximum output DC current of a single charging gun is below 250A. If the current is higher, the traditional charging gun charging method will no longer be suitable. If it is forced to output a large current, it will inevitably cause the cable to be too thick, making charging too labor-intensive. Therefore, for electric buses with relatively fixed operating lines, the automatic charging system using the charging bow as the interface has been widely recognized. However, the existing charging bow charging system has a simple s...
