Abstract

The invention relates to an electric vehicle direct-current interface circuit simulator which comprises a vehicle input socket, a load positive pole binding post, a load negative pole binding post, a control communication bus interface, a vehicle controller interface, a variable resistor, a loop resistor, a plurality of detection units and a plurality of disconnecting switches. Each detection unit comprises a detection switch and standard collection interfaces arranged at the two ends of the detection switch respectively. All the elements are connected based on the detection units and the disconnecting switches. According to the simulator framework based on the detector units, interoperability detection between electric vehicle direct-current charging piles is achieved, detection comprehensiveness is improved, and the electric vehicle accident rate is lowered.

Description

technical field [0001] The invention relates to the technical field of electric vehicle control and detection, in particular to an electric vehicle DC vehicle interface circuit simulator. Background technique [0002] With the continuous popularization of new energy electric vehicles, electric vehicle charging piles, which are the basic supporting facilities for new energy electric vehicles, are also becoming more and more popular. In the process of using electric vehicle charging piles to charge electric vehicles, the interconnection between the charging interface of the electric vehicle and the charging pile is particularly important, and the charging interface of the electric vehicle serves as a "bridge" between the electric vehicle and the DC charging pile , its working stability and the consistency of operation between electric vehicles and DC charging piles are the key. According to incomplete statistics, among the numerous electric vehicle accidents, 90% occurred dur...
