Abstract

The invention provides an electric vehicle universal charging interface and belongs to the field of electric vehicle charging. The electric vehicle universal charging interface comprises a male connector and a female connector; the female connector is provided with a main connection, an auxiliary connection I and an auxiliary connection II; the male connector is provided with a main plug, an auxiliary plug I and an auxiliary plug II; the main plug is provided with a channel in which a pyramid block is slidably arranged; the pyramid block is provided with a threaded hole; a screw is rotationally arranged in the channel of the main connection; the screw is in threaded connection with the pyramid block; one inner wall of the main connection is provided with a slide groove I in which a clamp block I is slidably arranged, and the other inner wall of the main connection is provided with a slide groove II in which a clamp block II is slidably arranged; the main connection is also provided with a push mechanism that may drive the clamp block I and the clamp block II to hold against the pyramid block. The electric vehicle universal charging interface allows a charger to be more stably connected with a charging pile, so that effectiveness of charging is guaranteed.

Description

technical field [0001] The invention belongs to the field of electric vehicle charging, and relates to a charging interface, in particular to a universal charging interface for electric vehicles. Background technique [0002] At present, a lot of work has been carried out in the demonstration application of electric vehicles in China, and some results have been achieved. However, there is a lack of systematic research on the overall design of the charging system. Compatibility and matching problems between modules have a significant impact on the stability of the charging system and the quality of harmonic power. The charging system is composed of a charger, and the charger is usually composed of charging modules such as a three-phase rectifier and a converter. [0003] There are various specifications and models of charging guns in existing charging stations or charging piles. Electric vehicles need to enter designated charging stations or charging piles to charge the corr...
