NOTE. a, b The accuracy of the resistors RC’ and R4’ is ±3%.
A.2.2.2 Confirm if the discharging connection device has been fully
connected.
The power supply control unit of the discharging vehicle places the CP at +12V
or outputs a 100% PWM duty cycle. Simulate the power supply mode in GB/T
18487.
If the discharging vehicle is fault free and the power supply interface is fully
connected, switch from the +12V state to the PWM connection state. Power
supply control device sends out PWM signal. The power supply control device
determines whether the discharge connection device is fully connected by
measuring the voltage value of the detection point 1 or the detection point 4.
A.2.2.3 Power supply equipment is ready.
The power supply control device determines whether the charging vehicle is
ready by measuring the voltage value of the detection point 1. When the peak
voltage of the detection point 1 is the voltage value corresponding to the state
3 in Figure A.3, the discharge vehicle starts to discharge.
A.2.2.4 Terminate discharging process.
In addition to the passive termination of the discharge process caused by the
failure of the vehicle or the connection device, the discharging vehicle shall
have the setting or operation measures for artificially terminating the discharge
process.
The state transition of the V2V control guiding circuit is shown in Figure A.3.
