Hope this helps. Alot more to it but this is a good start. Any more questions please ask. :)
And finally in short, whatever you do DON'T leave the car in Auto mode every day, drive it until the battery is dead no matter what and let it switch to EV later by itself. That's the wrong thing to do. You need to actively manage the battery usage.
I have the use mode that Stolenmoment describes for his daily commute. How he manages the car on longer trips on weekends makes sense, and seems to agree with what you prescribe, Raja. I get what you are saying now and for when that applies. To me, different length trips require different techniques depending on what you value most.
I have several driving modes that I routinely do. One is short 7 mile round trip commute to work. I definitely won't pass up free electric charging at work, so I will look for a shady spot to charge and keep the windows open a crack so the interior temp doesn't get too high. I get charging at night for the battery temp, but that is on my nickel and why drive up my electric bill if I can get it for free? "You know, if its free its for me." Is the battery that sensitive to hot summer charging? BTW, I am getting 5.5 KW out of the battery right now in EV now mode. My goal for this mode is free "fuel" and don't burn gas, so far it has been easy to achieve. I can charge every other day if I don't need the extra "juice" for errands after work.
Second mode is I drive around 50 miles which is a Mall trip or trip to the doctor's office. Gloucester is an island, so the saying is "you go ova da bridge". This is a mix of highway and around town. I will be using gas, so do the auto EV and EV later thing to use the battery on the around town part. I plan to use all the battery on the trip to minimize the amount of gas I use. Again, I don't burn gas if I don't have to. I will charge at home at night for this type of trip, which is usually on weekends.
Lastly is long highway trips, from 150-500 miles. Again, use auto EV and EV later to use battery around town and burn the gas on the highway.
I do question if just using auto EV mode and letting the battery get used up really uses more fuel?? I can see the battery getting drained faster on the highway resulting in fewer miles from the battery, but using the engine on the highway uses more gas than around town, so is there really a difference? I might try it on my 50 mile Mall runs and see what the car says.
Finally, I have a new driving mode that will last several months. I am on a new temporary work project that is in a different location. It is 24 miles from my house. I get free electricity there as well. So, I have been driving it starting with a full charge in EV now mode and making it with very little battery left. I charge at work to do the 24 miles home and charge at night at my house to do the 24 miles in the AM. So far, I have achieved no gas usage, which is great and my goal. Hopefully by the winter when I need heat it will be over and I will be back to my 7 mile round trip mode.
I tend to use EV now so the gas engine doesn't kick on if I go up a steep hill. By now I can see I would have to floor the pedal to make it kick on in EV auto mode, which I never do (well maybe once when I pulled out in front of someone) so it really doesn't matter too much. I just feel "greener" in EV now mode.
