#1, What is fast on the ICE? Mine always ran at 1500 rpms to warm up any time it starts. Its pegged to this rpm can cannot run any faster.
#2, Yes I'm talking about driving in the city with heat.
#3, If your engine starts, and you turn on the heat, the car uses the electric heater as well as the ice to warm up the coolant, together. Its ALWAYS like this until the coolant goes above 130 to 135F depending on OAT, then the ICE heat only is used. Its not trying to use excess power, its trying to make demanded heat as fast as possible.
#4 If you start the car and go down a hill regardless summer or winter, the ice will start if you use L or hill decent. If you hold the car back with the brake, the car is smart enough to cut off regen and not start the ICE.
Just remember, " During THAT time, the heat should only be helping to use some waste charge ", its not, its using electric heat to HELP the ICE warm the coolant as quick as possible. Using "waste charge" is never part of the equation, there is no such thing. If the battery is charged enough, the ice stops charging it which means gets better gas mileage.
