For the side of electric car, side of the CP signal transmitting units connection by electric car.
It is described for electric car interface and being designed with by electric car interface all there is three-phase alternating current electrical interface, N line interfaces, PE lines to connect
Mouth, CC signaling interfaces and CP signaling interfaces.Three-phase alternating current electric lead L1, L2 and L3, N lines and PE are correspondingly provided with inside control box
Line.Wherein CC signals are transmitted by PE lines, connect CP detecting signal units for the CP signals that electric car is sent, the CP received by electric car
Signal is sent to by CP signal transmitting units by electric car.
In three-phase alternating current electric lead L1, L2 and L3, respectively there are one hand over flow control switch, the friendship flow control switch not closed
When, the charging current that powered vehicle provides can not be transferred to by electric car side.Charge-discharge connecting device is mostly charging gun and puts
Electric rifle before charging gun pipette tips are to be established connection by electric car, can carry electric current if control box in pipette tips so that
Operating personnel have the danger of electric shock.Provided with control box and after handing over flow control switch, the control box can control charging
The break-make of electric current interrupts charging current, avoids operating personnel's electric shock when operating personnel operate.
CP detecting signal units are the amplitudes for detecting CP signals.Charging prepare different phase, CP signals
Amplitude is different, and the setting of CP detecting signal units can obtain current preparation state according to the amplitude of CP signals, with
Judge that connection hands over flow control switch whether suitable at this time.
The signal transmitted on CP signal wires is PWM wave signal, and electric vehicle is realized by detecting the state of PWM wave signal
Charging starts, charges and terminate and adjust charging current by adjusting the duty ratio of PWM wave signal.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
