Encrypted charging system and method for electric vehicle shared charging pile

Abstract

The invention discloses an encrypted charging system for shared charging piles of electric vehicles, including a two-dimensional code, a charging mode selection interface, a charging consumption calculation module, a charging timing module, a charging current detection module, a power-on control module, a charging locking mechanism and a central control The system, the charging method includes the following steps: insert the charging head into the charging socket of the electric vehicle; authorize the charging pile to obtain the user identity, and select any charging method in the charging mode of the charging mode selection interface, and put the charging head Locking; charge the electric vehicle with power on the charging head, record the charging time and monitor the current of the charging head in real time; control the unlocking of the charging head and disconnect the power supply of the charging head, and the next user will share the charging head; this scheme is effective Prevent others from unplugging the charging gun head to steal electricity to charge their own electric vehicles during the charging process, and automatically unlock the charging gun head and cut off the power to the charging gun head after the electric vehicle is fully charged.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an encrypted charging system and method for shared charging piles of electric vehicles.
