Vehicle charging system

Abstract

The invention provides a vehicle charging system. The vehicle charging system includes a charging pile and at least one vehicle locking device. The vehicle locking device is arranged in a parking space which is suitable for a vehicle to park and charge and used for locking the vehicle to the corresponding parking space. The charging pile include a first control device and at least one charging gun, and each charging gun includes an idle state and an use state; the first control device is used for sending a locking command to the vehicle locking device of a corresponding charging vehicle when any one charging gun is converted from the idle state to the use state and sending an unlocking command to the vehicle locking device of the corresponding charging vehicle when any one charging gun isconverted from the use state to the idle state. According to the provided vehicle charging system, the vehicle locking device is used for locking the charging vehicle when the charging gun is in the use state.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging piles, in particular to a vehicle charging system that actively protects charging piles and charging vehicles during charging. Background technique [0002] At present, the number of people who choose to travel with green and environmentally friendly electric vehicles continues to increase. The number of electric vehicles on the market is increasing year by year, and the demand for supporting charging piles for charging electric vehicles is also increasing year by year. [0003] During the charging process of electric vehicles, if the connection between the charging gun and the charging vehicle is suddenly disconnected, the instantaneous current generated in the charging circuit may cause electrical damage to the charging gun, charging pile or charging vehicle. [0004] Aiming at this problem, a solution generally adopted in the prior art is to set a protection circuit in the cha...

Problems solved by technology

[0006] However, due to the limited locking space provided by the connection end of the charging gun, such locking devices are generally small in size and strength, and the locking force that can be provided is limited.

Under the action of a large external force, even if the above protective measures are taken, the connection between the charging gun and the charging vehicle may be disconnected, and even cause mechanical damage to the locking device, increasing the maintenance cost of the charging gun and even the charging vehicle

Especially when the vehicle moves undesirably during the charging process, the existing solution cannot resist the external force generated by the movement of the vehicle at all, thus causing the lock to fail
