Circuit principle

One – way self – resetting electronic lock Two – way holding electronic lock
Free state Unlock state of charging gun and charging socket is:

the state between L-dect + and L-dect- is SI off;

Unlock state of charging gun and charging socket is:

the state between L-dect + and L-dect- is SI off;

Locked state After charging gun connected with charging socket,

the electronic lock wire Lock + and Lock- continuous

power 12 ± 1V,

electronic lock locked, and the state between L-dect +

and L-dect- changed to SI closed;

After charging gun connected with charging socket,

the electronic lock wire Lock + and Lock- continuous

power 12 ± 1V pulse voltage, that is, Lock + pass 12V

voltage,

lock- pass 0V voltage, the power time is shown as below.

Then electronic locked, L- Dect + and L-dect- are

transformed

from SI to closed state;

Unlock state If charge is terminated or the charging request is stopped,

the electronic lock wire will interrupted between Lock +

and Lock-, the electronic lock is disconnected, and

the L-dect + and L-dect- are changed to SI disconnected;

If charge is terminated or the charging request is

stopped, electronic lock wire between the lock + and

Lock- pass reverse pulse voltage, that is,

lock- pass 0V voltage,

Lock + pass -12V voltage, the power

time is shown as below.

Then the electronic lock is disconnected,

and the L-dect + and L-dect- are changed to SI disconnected;
