The invention discloses an electric vehicle central control system and method based on GPRS communication, and belong to the technical field of electric vehicle central control. The system and the method are used for overcoming the defect of function singleness of existing electric vehicles. The system comprise an RS485 bus communication circuit, a power supply circuit and a GPRS communication circuit. The power supply circuit is electrically connected with the RS485 bus communication circuit and the GPRS communication circuit respectively and is used for supplying power to the system; and theRS485 bus communication circuit and the GPRS communication circuit are in bidirectional electric connection. Interconnection among all parts in the electric vehicle is achieved through the RS485 buscircuit, and data of the electric vehicle are uploaded to a software platform with a data analyzing and processing function through the GPRS communication circuit. The GPRS communication circuit receives an instruction of the software platform and issues the instruction to the central control system, and the central control system issues the instruction to all parts of the electric vehicle throughthe RS485 bus communication circuit. A more intelligent and more convenient man-machine interaction mode is provided, and the electric vehicle can be checked and controlled from the far end.
