  1. 1. Should Preconditioning Energy be Included in MPGe?



Recommended Posts

My own opinion, but I don't think it should be included.  Yeah, I understand that you are using grid energy directly for the car to prep it and yeah, remote starting any gas car puts a dent in its fuel economy, but I just think the premise is different.  You're sourcing the energy directly from the grid and not using any 'stored fuel' in the vehicle, which is why I think it shouldn't be included.  It's kind of like continually topping off the car for heating and cooling needs.

It's the usage of a 'go time' or even remote starting the car while it's plugged in.  Both will use power from the wall instead of draining the battery or starting the ICE (in certain circumstances).

 

(I don't know what you know yet, so I'll cover the bases):

 

A Go Time is basically a scheduled run of the climate system in the car to set it to a temperature of your choosing for a departure time of your choosing.  This will not start the ICE and will use energy solely from the wall to bring your cabin temperature up if it's cold, or down if it's hot.  120v preconditioning is NOT effective in temperature extremes.  Larryh lives in MN and he tested 120v go times in ~10 degrees F weather and it pretty much did nothing to bring the temperature up.  240V is far more effective.  A Go Time may start warming or cooling your car up to an hour before you actually leave, depending on what the current ambient temperature is.

 

Remote Starting your car will accomplish the same thing, however, instead of having a variable window of a few minutes to an hour, it only has 15 minutes to bring your car to a set temperature.  If ambient temperature is too low, it will use both the wall outlet, stored battery energy, and in extreme cold or hot, will actually run the ICE to allow the climate system to consume the most energy and to get your cabin temperature from wherever it is to your set temperature.

 

Hope that answers your question. :)
