Abstract

The invention discloses an alternating current and direct current combined charging control system for an electric vehicle, and belongs to the technical field of control over charging of the electric vehicle. The alternating current and direct current combined charging control system for the electric vehicle comprises an alternating current and direct current combined charging interface recognition module, an alternating current and direct current combined charging handshaking module, a charging mode selection and parameter configuration module, a human-computer interaction module, a charging settlement module and a charging exception handling module. It is guaranteed that the electric vehicle is reliably and flexibly connected into a power grid to be charged, the charging flexibility is improved through the alternating current and direct current combined charging, the using efficiency of a charging stall is improved, the construction land area of a charging station is reduced, and therefore the land is saved, and foundation construction cost is lowered. The invention further provides a charging process control method suitable for alternating current and direct current combined charging equipment. The charging operation of the electric vehicle is managed in a humanized mode, the power distribution network efficiency is improved, and the utilization rate of charging equipment is improved.

Description

Technical field [0001] The invention belongs to the technical field of electric vehicle charging equipment control, and particularly relates to an electric vehicle AC-DC combined charging control system and control method. Background technique [0002] The invention relates to a charging process control method of an AC / DC combined charging device for an electric vehicle. The charging device can provide both AC and DC charging services at the same time to ensure the reliable and flexible access of the electric vehicle to the power grid. The use of AC and DC combined charging can increase the flexibility of charging, increase the efficiency of charging parking spaces, and reduce the land construction area of ​​charging stations, thereby saving land and reducing infrastructure costs. The AC-DC combined charging of electric vehicles is an important part of improving the user's charging experience and provides a platform for reasonable optimization of charging equipment according to t...
