Electric vehicle charging fault intelligent diagnosis system and method

Abstract

The invention discloses an electric vehicle charging fault intelligent diagnosis system and a method. The diagnosis system comprises an information acquisition module, a fault judgment module and a fault processing module, wherein the information acquisition module is used for acquiring fault codes, on-off state information and operation state information of a power battery, a charging pile and power supply equipment, and sending the fault codes and the information to the fault judgment module; the fault judgment module is used for determining the fault position and level according to the information sent by the information acquisition module; and the fault processing module is used for giving a warning or cutting off a power supply circuit according to the judgment result of the fault judgment module. By analyzing the integrated safety action mechanism among the power battery, the charging pile and the power supply equipment and performing corresponding safety decision and control execution according to the fault influence type, diagnosis of the charging fault of the electric vehicle can be quickly realized, the fault point can be found out, and the charging safety of the electricvehicle is effectively improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an intelligent diagnosis system and method for charging faults of electric vehicles. Background technique [0002] As one of the main development directions of new energy vehicles, electric vehicles are getting more and more attention. As the number of electric vehicles continues to increase, the issue of charging reliability and safety has become the focus of domestic and foreign scholars and industrial circles. Under the current situation of different types of charging facilities and different natures of service providers in my country, how to realize the interconnection of basic charging facilities for electric vehicles and ensure integrated charging safety warning is one of the current problems that need to be solved urgently. [0003] In order to ensure the safe driving of electric vehicles, prevent major personal injuries and property losses caused by power batte...
