A kind of AC and DC dual-purpose self-service charging system

Abstract

The invention discloses an AC and DC dual-purpose self-service charging system. A linear motor is also provided in the inner cavity of the box, and a slide rail is fixedly installed on the bottom surface of the inner cavity of the box, and a slide block is installed on the slide rail, and the slide block can slide along the length direction of the slide rail, and the slide block One end face of the slider is fixedly connected with the telescopic rod of the linear motor, and the other end face of the slider corresponds to the push-type spring switch on the left side of the inner cavity of the box. The take-up roller is installed, the gear is also fixedly installed on the rotating shaft, and two charging plug mounting seats are fixedly installed on the right side of the box body, and charging plugs are all installed on the two charging plug mounting seats. The beneficial effect of the invention is that the self-charging function can be realized.

Description

technical field [0001] The invention relates to the technical field of AC and DC charging, in particular to an AC and DC dual-purpose self-service charging system. Background technique [0002] With the concept of green life and low-carbon travel becoming more and more popular, green and energy-saving new energy vehicles have gradually entered people's lives. At this stage, electric vehicles in the field of new energy have been widely used. In order to ensure the smooth travel of people, it is necessary to provide corresponding charging systems for electric vehicles. The existing charging systems can be divided into DC charging mode, AC charging mode and AC-DC dual-purpose charging mode. The charging system undertakes the tasks of supplementing electric energy for electric vehicles, controlling the charging process and protecting abnormal charging. [0003] Most of the current charging systems are AC charging systems, while DC charging systems are rare, and AC and DC charg...

AI Technical Summary

Problems solved by technology

However, there are still problems in the safety performance of the existing AC and DC self-service charging systems;

[0005] First of all, the existing AC-DC dual-purpose self-service charging system is also exposed to the outside of the charging line when it is not in use. Even if the charging line is built into some systems, it is easy to be pulled out, and there is a big safety hazard;

[0006] Secondly, the existing AC and DC dual-purpose self-service charging system will still be powered on when not in use, which not only has the risk of leakage, but also accelerates the aging of the internal electronic components of the charging system after being powered on for a long time, thereby affecting its use. life
