Shown in reference picture 4, the circuit in charging equipment use state in the utility model embodiment is illustrated in the figure
Annexation, when user needs to be charged, control element judges whether the state of charging gun is plug in rifle first, by filling
The voltage change signal of electricity condition detecting element judged, as shown in figure 4, when user does not plug in rifle, due to the first detection electricity
R1 and the second detection resistance R2 electric resistance partial pressures are hindered, the voltage U1 of test point 1 is 6V, due to the first detection resistance after user plugs in rifle
R1, the second detection resistance R2 and charging vehicle resistance connection in series-parallel partial pressure, the voltage of test point 1 are changed into 4V, and control element is according to the electricity
The variable signal of pressure judges that charging gun plugs in rifle;
And charging vehicle is to judge whether charging gun inserts charging inlet by detecting test point U2 voltage change, when
Charging gun inserts charging inlet, and the plug state detection resistance 101 of charging gun can be linked into the charging gun detection of the charging vehicle
In circuit, now the charging gun detection circuit of the charging vehicle is by the detection resistance R5 of plug state detection resistance 101 and the 3rd
Partial pressure;When in not slotting gun state, only the 3rd detection resistance R5 partial pressures in the charging detecting circuit of charging vehicle, Jin Erke
To meet that charging vehicle by detecting test point U2 magnitude of voltage, judges whether charging gun inserts, when delay switch 101 disconnects
When, interior only the 3rd detection resistance R5 partial pressures, and then now charging vehicle judges charging gun of charging detecting circuit of charging vehicle
Charging inlet is not inserted into, when delay switch closes again, charging gun detection circuit becomes as by plug state detection resistance again
101 and the 3rd detection resistance R5 partial pressure;With this among charging process in the event of suddenly power-off cause charging interrupt when, when with
When family triggering charging instruction is charged again, delay switch closes after disconnecting preset time automatically, now charging vehicle meeting
Think to have completed once plug gun state, and then can not manually carry out plugging rifle manually and can be charged again;Side
Just it is quick.
