If the driver adjusts a desired temperature at the IHKA controls, the IHKA
calculates a corresponding
nominal temperature and compares it to the actual output temperature of the
electrical heating.
When the coolant temperature is low, for example after driving off, or in
all-electric driving, the electric
changeover valve is activated by the Body Domain Controller (BDC). The

As in previous BMW hybrid vehicles, an electrically powered air conditioning
compressor is used in
the G20 PHEV. Because the A/C compressor has an electric motor, it is possible
to operate the air
conditioning independently of the combustion engine. Thus the customer can enjoy
the cooling ef
