Electric vehicle safety charging station with high charging gun utilization rate and low manufacturing cost

Abstract

The invention belongs to the technical field of electric vehicles and particularly relates to an electric vehicle safety charging station with the high charging gun utilization rate and low manufacturing cost. The charging station is composed of two or more charging circuits corresponding to mechanical storage device hangers in number. Each charging circuit is composed of a charging gun and a charging cable. The charging circuits are connected with a power distribution cabinet. A mechanical storage device comprises a high overhead rail and a tension spring balancer, wherein two or more sliding hanging wheels are installed on the high overhead rail, the sliding hanging wheel on the side close to the charging guns is connected with the tension spring balancer. The tension spring balancer is connected with the charging guns or the charging cables connected with the charging guns. The sliding hanging wheel on the side close to a power distribution cabinet is connected with the charging cables. According to the charging station, the charging gun using efficiency is greatly improved, the manufacturing cost of the charging station is greatly decreased, and the maintenance cost is greatly decreased; the charging guns and the charging cables will not touch the ground all the time, and the safety can be improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a charging station for electric vehicles. Background technique [0002] At present, the main form of external charging devices for electric vehicles is the way of configuring a charging pile in a parking space. There are two problems in this way. 1. The utilization rate of the charging gun is low. When a car is fully charged but does not leave, the charging at this time The gun is already free, but if you want to use this charging gun to charge a car in an adjacent parking space or a car farther away, theoretically as long as the charging cable is long enough, but in actual use, the charging cable is too long if it is not safely stored Under the circumstances, there are potential safety hazards, so the charging cable cannot be set too long at present, the parking space covered by the charging gun of a charging pile is limited, and the utilization rate of the...

[0002] At present, the main form of external charging devices for electric vehicles is the way of configuring a charging pile in a parking space. There are two problems in this way. 1. The utilization rate of the charging gun is low. When a car is fully charged but does not leave, the charging at this time The gun is already free, but if you want to use this charging gun to charge a car in an adjacent parking space or a car farther away, theoretically as long as the charging cable is long enough, but in actual use, the charging cable is too long if it is not safely stored There are potential safety hazards, so the charging cable cannot be set too long at present, the parking space covered by the charging gun of a charging pile is limited, and the utilization rate of the charging gun is not high

2. As far as the length of the current charging cable is set, when charging the electric vehicle or putting the charging gun back on the charging pile, the charging cable is often mopped to the ground, which is easy to wear the cable sheath and cause safety hazards

[0003] There have been technical solutions to try to solve the problem of safe storage, such as: the published CN104505674A "high-position retractor for charging cables", this technical solution has selected high-position charging cables in terms of safety, and solved the potential safety hazard of cable mopping the floor , but the storage device adopts a relatively complex mechatronic control system, the length of the storage cable is limited, the advantages of convenience of use, manufacturing economy, and the utilization rate of the charging gun are not significant
