Control system and control method of electric automobile charging gun electronic lock

Abstract

The invention provides a control system and a control method of an electric automobile charging gun electronic lock. The control system of the electric automobile charging gun electronic lock comprises an isolation driving module, a logical negation locking module, an unlocking switch module, a power switch module and a feedback recovery module, wherein the isolation driving module receives a control signal, isolates the control signal, and then outputs the control signal to the logical negation locking module and the unlocking switch module, low electrical level is output when the control signal is at the low electrical level, high electrical level is output when the control signal is at the high electrical level, a main circuit in the logical negation locking module is switched on so asto lock the electronic lock when the control signal is at the low electrical level, the main circuit in the logical negation locking module is switched on so as to unlock the electronic lock when thecontrol signal is at the high electrical level, the power source switch module provides power sources to follow-up modules, and the feedback recovery module isolates the state of the electronic lock,feeds the state of the electronic lock back to a control chip, and enables a control end to respond and turn off a power switch, thereby saving power consumption. The control system for the electric automobile charging gun electronic lock prevents temperature environment and life of effective use of the product from depending on an aluminum electrolytic capacitor, enlarges the scope of the temperature range of the effective use, and prolongs the effective use life.

Description

Technical field [0001] The present invention relates to the technical field of charging and swapping electric vehicles, in particular to a control system and control method for an electronic lock of an electric vehicle charging gun. Background technique [0002] Traditional electronic lock control circuits mostly use a combination of aluminum electrolytic capacitors and relays, which are extremely dependent on the performance of electrolytic capacitors in electrical performance, and are easily affected by high and low temperatures; after finalization, the pulse width of charging guns of different manufacturers and models cannot be adjusted , The versatility is not high; the structure is large in size, and the mixed installation of multiple paste plug-ins is not conducive to the automatic production of products. However, it is difficult for circuits driven by MOS to simultaneously meet the requirements of the electronic lock drive voltage and the instantaneous large drive current,...
