Self-adaptive charge control system for electric vehicles on basis of SDP (SECC (supply equipment communication controller) discovery protocol) and V2GTP-EXI (vehicle to grid communication transport protocol-efficient XML interchange) and control method of control system

Abstract

The invention relates to a self-adaptive charge control system for electric vehicles on the basis of an SDP (SECC (supply equipment communication controller) discovery protocol) and a V2GTP-EXI (vehicle to grid communication transport protocol-efficient XML interchange) and a control method of the charge control system. The self-adaptive charge control system comprises an energy supply equipment communication controller SECC, and the SECC comprises a main controlling CPU (central processing unit), a power source module, a sampling module, a man-machine module, an in / out module, a guidance control module, and a PLC (programmable logic controller) module. The main controlling CPU is used for scheduling a charge system of an electric vehicle, processing and controlling data. The power source module is used for supplying power source for the SECC. The sampling module is used for collecting voltage and current information and uploading the same to the main controlling CPU. The man-machine module is used for interface displaying and keyboard inputting. The in / out module is used for collecting switching value and state value, uploading the same to the main controlling CPU, and executing control commands of the main controlling CPU. The guidance control module is used for monitoring state of a guidance control wire and uploading the state to the main controlling CPU. The PLC control module is used for converting network communication data between the main CPU and an EVCC (electric vehicle communication controller) into carrier data. By information interaction between the EVCC and the SECC of a plug-in electric vehicle, interaction V2G (vehicle to grid) between the electric vehicle and the power grid is realized, and self-adaptive charging of the electric vehicle is completed.

Description

technical field [0001] The invention relates to electric vehicle charging and swapping technology, in particular to an electric vehicle adaptive charging control system based on SDP and V2GTP-EXI and a control method thereof. Background technique [0002] With the depletion of global oil resources, the cost of using oil-derived fuels continues to rise. At the same time, in order to improve efficiency and reduce air pollution, the automotive industry has introduced new types of vehicles that use electricity delivered to the grid by various power stations as necessary These new models, called electric vehicles, use the energy to power vehicles instead of relying on internal combustion engines. Electric vehicles will become a major segment of the automotive market, gradually replacing conventional vehicles powered by internal combustion engines. [0003] In the face of high international oil price fluctuations and increasingly severe pressure on energy conservation and emissio...

Problems solved by technology

[0008] At present, domestic AC and DC charging facilities rarely have the function of electric vehicle interaction, and some DC charging facilities only have CAN interface for future communication and interaction, and have not yet used the carrier on the guidance control and the charging control function based on SDP and EXI technology
