Control system and control method for electronic lock of charging system

Abstract

The invention provides a control system and a control method for an electronic lock of a charging system. The control system comprises an electronic lock locking circuit, wherein the electronic lock locking circuit comprises energy storage capacitors, a first locking relay, a second locking relay, the electronic lock, anti-blocking diodes and an auxiliary source taken as a power source; an input positive end of the auxiliary source is connected with a normally open end of the first locking relay after being connected in series with at least one anti-blocking diode, and a positive power supply network is formed; at least one energy storage capacitor is connected in series between a cathode of a diode group consisting of the at least one anti-blocking diode and a ground end of the auxiliary source to constitute an energy storage network, and the cathode and a normally open end of the second locking relay are connected together to constitute a negative power supply network; normally closed ends of the first locking relay and the second locking relay and the ground end of the auxiliary source are connected to constitute an earthing network; contact output ends of first locking relay and the second locking relay are connected with a positive end and a negative end of the electronic lock respectively, and unlocking positive and negative input networks are formed.

Description

technical field [0001] The invention relates to a charging system locking device, in particular to a charging system electronic lock control system and a control method. Background technique [0002] The rapid development of new energy electric vehicles has once again ignited a new trend in the development of the power electronics industry, and a new energy revolution is coming quietly. As the link between nuclear power generation, photovoltaic power generation, wind power generation and electric vehicles, charging piles run through the ecological chain of the entire new energy ecosystem, guiding the vigorous development of the new energy industry and laying a solid foundation for the development of the new energy industry. Base. However, the issue of charging safety has always been the focus of the entire charging industry. Therefore, the relevant requirements of the national standard GB / T 20234.1-2015 clearly stipulate that the charging system must have a locking function...

AI Technical Summary

Problems solved by technology

At present, there are situations where the old station is rebuilt or the new national standard is cut in, causing the charging system to be incompatible with level and pulse electronic locks, resulting in the phenomenon that the electronic lock cannot be locked during charging or the electronic lock cannot be unlocked in time after charging.

If the type of electronic lock is not clear, if a level signal is applied to the pulse electronic lock for a long time, magnetic saturation will occur, causing the PCB to burn or even catch fire, posing a considerable safety hazard
