Residential-community electric automobile charging system

Abstract

The invention discloses a residential-community electric automobile charging system. The system comprises a charging statistics module, a first power module, a second power module, a charging determination module, a charging time setting module, a charging display module, a first communication module, a second communication module and a controller. A charging pile is provided with the charging determination module so as to determine whether an electric automobile begins to be charged according to an acquired charging quantity, charging time, first power, a maximum power limiting value, second power and the like. The electric automobile satisfying a charging condition can be charged at an electricity price valley value period so that charging cost is saved. A large scale of the electric automobiles in a residential community can be charged in order after accessing a power grid so that negative effects on safe and economic operation of an electric power system are avoided. The charging time setting module is set so that a user sets automobile use time according to a need and a condition that the automobile is not fully charged when the user wants to go out is avoided. The charging display module is set so that the user can conveniently and visually acquire charging information of the electric automobile.

Description

Technical field: [0001] The invention belongs to the technical field of electric vehicle charging control, and in particular relates to a residential area electric vehicle charging system. Background technique: [0002] Under the background of the global energy crisis and environmental crisis, the national government is actively promoting the application and development of new energy vehicles, and the use of electric energy to replace traditional petroleum fuels can reduce greenhouse gas emissions and dependence on petroleum. Major automobile companies have already begun the industrialization process of EV (Electric Vehicle). As a green transportation tool with broad development prospects, electric vehicles will be popularized very rapidly in the future, and the future market prospects will be extremely huge. [0003] At present, electric vehicles in residential areas usually enter the parking lot, find a parking space with a charging device to park, and then charge by inse...

AI Technical Summary

Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that the electric vehicle charging time in the residential area in the prior art belongs to the peak period of electricity price, the charging cost is high, and the disorderly charging after the large-scale electric vehicle is connected to the power grid will cause serious damage to the power system. Safety and economic operation bring serious negative impacts, so a charging system for electric vehicles in residential quarters is proposed
