Abstract

The invention discloses a system and method for communication of an electric automobile and power supply equipment. According to the system and method, communication protocols are additionally arranged on an automobile control device of the electric automobile and a charging control device of the power supply equipment, and thus the automobile control device communicates with the charging control device through a signal line CP. Therefore, according to the system and method, a standard plug connector interface and the number of core wires of an existing electric automobile and existing power supply equipment do not need to be changed, hardware does not need to be added, the effect can be achieved only by updating software, the achieving cost is low, and transformation of the existing electric automobile and the existing power supply equipment is convenient. According to the system and method, interactive communication can be achieved between the electric automobile and the power supply equipment, and thus monitoring of the current, voltage, temperature and charged state of charging of the electric automobile by the power supply equipment is achieved, so that the charging safety is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a system and method for communicating between an electric vehicle and a power supply device. Background technique [0002] With the increasing awareness of environmental protection and energy saving, electric vehicles are gradually favored because they are powered by on-board power supplies, which can solve the problems of fuel vehicle exhaust emissions polluting the environment and high energy consumption. Electric vehicles are the future direction of the development of the automobile industry, and the charging facilities that match the rapid development of electric vehicles are the basis for the energy supply and application of electric vehicles. At present, in the standard of the charging interface (GB / T 20234.2-2015), there is no specific method for the interface communication between the power supply equipment and the electric vehicle, but only a simple jud...
