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 Ldect- 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 isshown as below.

Then the electronic lock is disconnected,

and the L-dect + and L-dect- are changed to

SI disconnected;
