A control system and control method for electric vehicle charging gun electronic lock

Abstract

The present invention provides a control system and control method for an electronic lock of an electric vehicle charging gun, including: isolating a drive module, receiving a control signal, and outputting to a logic non-locking module and an unlocking switch module after isolation, when the control signal is low output low level when the control signal is high level; logic non-locking module, when the control signal is low level, the internal main circuit of the logic non-locking module is turned on, so that the electronic lock is locked ; Unlock switch module, when the control signal is high level, the internal main circuit of the logic non-lock module is turned on, so that the electronic lock is unlocked; the power switch module provides power for subsequent modules; the feedback recovery module isolates the state of the electronic lock Feedback to the control chip, so that the control terminal responds to turn off the power switch to save power consumption. The invention avoids the dependence of the effective use temperature environment and service life of the product on the aluminum electrolytic capacitor, and expands the effective use temperature environment range and service life.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging and swapping, in particular to a control system and control method for an electronic lock of a charging gun of an electric vehicle. Background technique [0002] The traditional electronic lock control circuit mostly uses a combination of aluminum electrolytic capacitors and relays, which is extremely dependent on the performance of electrolytic capacitors in terms of electrical performance, and is 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; in the structural process, the volume is large, and the mixed installation of multiple plug-ins is not conducive to the automatic production of the product. However, it is difficult to meet the requirements of the electronic lock driving voltage and the instantaneous large driving current with the circ...
