5.7 Activation mode
Figure 5-7 Typical curve of signal CP in activation mode
If the connected vehicle switches from status B1 (9 V DC) to status B2 (9 V PWM) and the
vehicle does not enter status C or D within 30 seconds, the charging controller simulates the
disconnection of the vehicle from the charging station.
The CP signal is set to -12 V DC for 3 seconds. It then switches back to the PWM signal.
After transition from status A1 or B1 to status B2, this process is performed not more than
once.
Activation mode is performed again
– If the vehicle is disconnected from the charging controller and then reconnected again
or
– If the charging process was interrupted by the charging station (e.g., for reasons of load
management).
