REVO-E Heat pump 4 Function and functional schematics
4.4.9 Waste Energy Mode
Requirements:
– Clamp 15 active (ignition)
– Vehicle hybrid system active
– The HVAC's power needs are enabled by the signal
"D_AuxiliaryPowerEnabled"
– “D_CabAcWasteEnergyReq” signal is requested by
the BEA body
– Environmental temperature >5°C
In Waste Energy Mode, the air-conditioning system
attempts to dissipate additional energy from the drive
battery.
This is achieved by running back the efficiency of the air-
conditioning system, e.g. by reducing the speed of the
axial fans.
The reduction in power must occur without any noticeable
change to the conditions in the passenger cabin. This
mode is only used to support the power management
system.
The maximum condenser capacity can in turn be limited
by the "D_ElAcMaxPowerAllowed" signal.
