I'm afraid you're missing the point of Charge and Save. When the battery is empty (or when you press Save), the car will use the ICE to charge the battery, running in what is in effect Charge mode. Once the range has increased by a mile or so, it will drop back to EV till the range drops to the previous level. So the car will use Charge mode intermittently whatever you do once it stops using pure EV. Pressing CHRG will make the ICE run in Charge mode continuously, so increasing your range until you turn it off or it reaches its limit. In fact, it is ever so slightly more economical to run it in Charge for longer periods and use EV for longer, but that is in tests in Australia where they can maintain a steady load for long periods.
So using Charge mode strategically is little different to leaving it to its own devices on a long journey, as long as you arrive at you destination with an empty battery. When running in Parallel mode above 40mph, the ICE is powering the wheels directly, and is more efficient than in Series mode where the ICE powers the generator to power the electric motors, which has more losses. So using CHRG on faster roads (where the car runs in Parallel mode) to charge the battery so that you can use EV around town (where the car would run in Series mode) makes sense for MPG, as long as you arrive at your next charge point with an empty battery.
I'm a new Outlander owner as well. I am wondering the same thing about how to use the Charge button, and if it is worth it at all. You seem to have given the most succinct answer that I have read so far.
Tell me if I am interpreting it right.... Let's say you are going on a 40 mile trip each way. You start out with a full wall charge. At the beginning and end of this mostlyhighway journey, you will be doing some local stop-and-go driving (4-5 miles on either side). Highway speed will be between 50 and 65 MPH. You will not be able to charge at your destination, but you will when you get home. If I understand you correctly, it is best to press the charge button for the time you are traveling 50 mph or better on the first leg of the trip to keep/restore the battery to maximum charge (80%), then on the way home use the Charge button until you are within 20 miles of home, then try to run the battery down to near zero by the time you get home?
Would this be a proper use for best mpge?
