Intelligent alternating current charging pile and charging method of electric automobile

Abstract

The invention discloses an intelligent alternating current charging pile and a charging method of an electric automobile. The charging pile comprises a central control module, a GPS (Global Positioning System) positioning signal receiving and dispatching module, a human-computer interaction module, a metering module, an electric module and a communication module, wherein the GPS positioning signal receiving and dispatching module, the human-computer interaction module, the metering module, the electric module and the communication module are connected with the central control module through signal lines; the input end of the metering module is further connected with a protection module; an alternating current input by a power grid goes through the protection module and the metering module in sequence to reach the electric module; the electric module comprises a power supply switching unit, a battery detection unit, a current sensing unit, an abutting joint sensing unit and a charging connector. According to the charging pile and the charging method disclosed by the invention, through real-time interaction of a plurality of modules, great convenience for charging the electric automobile is brought for a user, and a convenient access for the management of the charging pile is provided for a charging pile operating agency, so that the utilization rate of the charging pile is improved, the manageability of the charging pile is enhanced, and the management, using and maintenance costs are reduced.

Description

technical field [0001] The invention relates to an electric vehicle intelligent AC charging pile and a charging method thereof, belonging to the technical field of electric power. Background technique [0002] Electric vehicles refer to vehicles powered by vehicle-mounted power supplies and motor-driven wheels that meet the requirements of road traffic and safety regulations. Compared with gasoline engine vehicles, electric vehicles have less impact on the environment and can replace the use of non-renewable energy gasoline. Therefore, the prospect of electric vehicles is widely optimistic, and it also meets the requirements of new energy strategies. [0003] The electric vehicle charging pile is a power supply device that is fixedly installed outside the electric vehicle and connected to the power grid to provide power for the on-board charger of the electric vehicle. Traditional charging piles include: pile body, electrical module, protection module and metering module. ...

AI Technical Summary

Problems solved by technology

Each module has a single function and is independent. At most, some charging status information is output to the charging pile display system or the system of the power management department. There is less information interaction with the user, and it is impossible to actively provide the user with charging status information. Battery status Information, charging pile location information, whether the charging pile is free, charging start and end information, fee and settlement success information, etc.

[0004] In addition, when the charging quantity cannot meet the growing number of electric vehicles, the user may find a charging pile with great difficulty but finds that someone is already charging, and the user can only wait endlessly in place or find another charging pile. , and it is impossible to predict whether it will be possible to find
