Via the CP signal (Control Pilot), the device specifies the permissible charging current value
to the vehicle which is coded as a PWM signal. The vehicle indicates the current vehicle sta-
tus via the voltage value Va. The assignment of the permissible charging current value to
the pulse width of the PWM signal and the assignment of the voltage value to the vehicle
states is defined in IEC 61581-1 (see table
