Table 5- 2 List of output parameters
State Byte Charging state
The state is output at this output largely according to IEC 61851-1.
• 0: Charging outlet blocked
(no state according to IEC 61851-1)
• 1: State A
(state according to IEC 61851-1)
• 2: State B
(state according to IEC 61851-1)
• 3: State C
(state according to IEC 61851-1)
• 4: State D
(state according to IEC 61851-1)
• 5: State E
(state according to IEC 61851-1, but is also displayed in case of CP error; the voltage
at the CP output remains at +12 V, PWM is disabled in this case)
• 6: State F
(state according to IEC 61851-1)
Max. CP voltage value (in Volt)
ContactorContr Bool Load contactor state (module DQ state) (True = contactor on; False = contactor off)
This output can be used for additional evaluations of the load contactor state in the TIA
application (e.g. counting switching cycles for maintenance purposes).
LockControl Bool Locking (True = yes), Unlocking (False = no)
This output can be used for additional evaluations of the locking state in the TIA application
(e.g. for external control of locking the charging cable connector).
VentilationReq Bool Ventilation required (True = yes, False = no)
This output signals that ventilation must be connected (State D according to IEC 61851-1).
PWM_State Bool PWM enabled (True = on, False = off)
This output indicates whether PWM is switched on or off. PWM is disabled in case of CP
voltage errors, locking feedback errors or ventilation feedback errors. This signals to the
vehicle that charging is not possible under these circumstances.
MaxCableCurr Real Maximum detected current carrying capacity of the cable in ampere based on PP evalua-
PWM_MaxCurr Real Charging current [in ampere] signaled to the vehicle using PWM
(minimum of the three values "FC input MaxCurr", "Current carrying capacity of the cable"
and the parameter "Maximum charging current")
