ICEheaterStop optional module enables full electric heating of cabin in most weather & temperature conditions. Gasoline engine will start only if it is cold, consumption of fuel for heating will be reduced by 70% (average).
Explanation: There are three different channels (triggers) that can cause ICE to start: heating of cabin (that we reduce with ICEheatStop), preheating of oil/engine in winter to avoid demolishing engine by rapid full power demand while frozen, and finally – traction power demand.
ICEheatStop blocks usage of ICE for cabin heating, ICE Ecu still may preheat ICE oil without any load (and without electricity production) for 30 sec – 2 min (depends on external temperature). Fuel consumption for that preheating is very low – much lower than when engine is additionally loaded with power generator to speed up ICE->cabin heating.
