All voltages are measured after the stabilization phase, tolerance ±1 V.
a)
The generator of the ESVE can use a stable direct voltage or a ±12 V square wave signal during this phase.
b)
The measured voltage is a function of the R3 value.
c)
Plug Present signal PP0 and PP1
The technology module determines for every charging outlet the current carrying capacity of
the connected charging cable via the Plug Present interface (also referred to as the
Proximity interface). Please also note the adjustable parameters
