Lifting type charging device, charging pile and lifting type charging device motion control method

Abstract

The invention relates to a lifting type charging device, a charging pile and a lifting type charging device motion control method. During charging, a power source drives a charging frame to drive a charging positive electrode, a charging negative electrode and a charging grounding electrode to descend through a lifting mechanism, and the power source is a servo motor or comprises the servo motor. When the charging grounding electrode is in contact communication with the corresponding electrode on the electric vehicle before the charging positive electrode and the charging negative electrode, the servo motor decelerates to reduce the falling speed of the charging frame until the charging frame falls to a charging position. When the charging frame is located at the charging position, the charging positive electrode, the charging negative electrode and the charging grounding electrode on the charging frame are all in contact communication with corresponding electrodes on the electric vehicle to achieve normal charging. Impact force generated when the subsequent charging positive electrode and charging negative electrode make contact with corresponding electrodes on the electric vehicle is effectively reduced, extra impact abrasion is reduced, and the service life of the charging positive electrode and the charging negative electrode is prolonged.

Description

technical field [0001] The invention belongs to the technical field of charging devices, and in particular relates to a lifting charging device, a charging pile and a motion control method for the lifting charging device. Background technique [0002] With the development of society, more and more electric vehicles are used, users' demand for driving range is getting longer and longer, the battery capacity of electric vehicles is increasing, and the demand for high-power commercial vehicles is increasing. At present, high-power commercial vehicles generally adopt the top charging method. The on-board electrodes on the vehicle are docked with the charging electrodes on the charging pile to realize charging. The common structure is the scissor type disclosed in the Chinese utility model patent with the authorized announcement number CN209159430U. Charging bow. When in use, the top of the charging bow is installed on the charging pile. When charging is required, the servo motor...
