Abstract

The invention provides a charging control system for an electric automobile. The charging control system comprises a power battery, a charging and discharging socket, a bidirectional DC / AC (direct current / alternating current) module, a charging and discharging control module and a controller module, wherein the charging and discharging socket is connected with an external power supply; the first direct current end of the bidirectional DC / AC module is connected with the other end of a drive control switch, and the second direct current end of the bidirectional DC / AC module is connected with the other end of the power battery; one end of the charging and discharging control module is connected with the alternating current end of the bidirectional DC / AC module, and the other end of the charging and discharging control module is connected with the charging and discharging socket; the charging and discharging control module comprises a three-phase charging branch circuit and a signal phase charging branch circuit, so that three-phase charging and discharging or single phase charging and discharging can be respectively realized; the controller module is connected with the charging and discharging control module, and is used for determining the rating of the external power supply, when the rating of the external power supply is three-phase, the controller module is used for controlling the startup of the three-phase charging branch circuit, and when the rating of the external power supply is single-phase, the controller module is used for controlling the startup of the single-phase charging branch circuit. The invention also provides the electric automobile.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle charging control system and an electric vehicle with the charging control system. Background technique [0002] With the development of the automobile industry, environmentally friendly and energy-saving electric vehicles are playing the role of replacing fuel vehicles. However, the popularity of electric vehicles still faces some problems. Among them, high mileage and fast charging technology have become a part of the promotion of electric vehicles. Big problems, especially safe and reliable on-board fast charging devices, have gradually become the main concern of the industry. [0003] At present, most electric vehicles use large-capacity batteries. Although the battery life of electric vehicles can be improved, the same large-capacity batteries also bring about the problem of long charging time. Although professional DC charging stations can quic...
