Abstract

The invention discloses an electric vehicle DC charging interface connection state detector. The detector comprises a test socket used for connecting with a to-be-detected charging gun, a test plug used for connecting with a to-be-detected vehicle DC charging socket, and a test board used for testing a connection state of each pin of the to-be-detected charging gun and the to-be-detected vehicle DC charging socket. The detector is advantaged in that charging interface connection state detection is carried out on the condition that the charging gun and the electric vehicle DC charging socket are in a perfect state without damage, whether connection abnormality occurs is determined, fault causes are made to be clear when connection abnormality occurs, safety and reliability of electric vehicle charging are effectively guaranteed, and popularization and application of electric vehicles are facilitated.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an electric vehicle DC charging interface connection state detector. Background technique [0002] A few days ago, the National Development and Reform Commission, the National Energy Administration, the Ministry of Industry and Information Technology and other departments jointly issued the "Guidelines for the Development of Electric Vehicle Charging Infrastructure (2015-2020)" and the "Guiding Opinions on Accelerating the Construction of Electric Vehicle Charging Infrastructure" issued by relevant departments. The goal of my country's charging infrastructure development is to build 12,000 centralized charging and swapping stations and 4.8 million decentralized charging piles by 2020 to meet the charging needs of 5 million electric vehicles nationwide. The General Administration of Quality Supervision, Inspection and Quarantine, the National Standards Committee, ...
