Electric vehicle charging gun head electronic lock control method, device and electronic lock device

Abstract

The invention relates to an electric automobile charging gun head electronic lock control method and device and an electronic lock device. When a system power source is powered off or a vehicle control unit has no active out related to electronic lock unfastening, a control module outputs an electronic lock unfastening control signal. Therefore, when the system power source is powered off or the vehicle control unit has no active out related to electronic lock unfastening, an electronic lock can still be controlled, the electronic lock can be controlled to be unfastened no matter an electric automobile is completely charged or not at the moment, it is guaranteed that the electric automobile is disconnected from a power grid, a charging gun head can be smoothly pulled out of the electric automobile, a user can continuously use the electric automobile, and user experience is improved.

Description

technical field [0001] The invention relates to an electronic lock control method and device for a charging gun head of an electric vehicle and an electronic lock device. Background technique [0002] In the environment of low-carbon environmental protection and green travel, more and more families choose electric vehicles as a means of transportation, and the safety and reliability of electric vehicle charging have become the primary considerations of users. At present, the vast majority of electric vehicles are charged by connecting the charging gun to the grid. The safe and reliable operation of the charging gun is particularly important for the electric vehicle charging system. Therefore, the new national standard proposes to control the electronic lock and temperature of the charging gun head to ensure the safety of the charging system. by running. [0003] Such as figure 1 As shown, the electronic lock has two signal input terminals LOCKA and LOCKB, wherein LOCKA is ...
