stevedebi Posted April 30, 2015 Report Share Posted April 30, 2015 Jack may be smiling but Ford's EV+ programmers are laughing - possibly rolling on the floor laughing - as they read these posts! They put a bunch of "Easter Eggs" in the software just to keep us guessing! Endless possibilities:Turn ON going by any Dealer location (but only if you haven't visited one in 30 days!)Turn ON going by Henry Ford's birthplace (but only on his birthday)Refuse to turn ON if the microphone picked up a naughty word during the driveAdjust activity based on phases of the moon, etc, etcWe bought a GPS some years ago that "magically" started predicting where we are going by putting up messages like "3 Minutes to Dump" or "9 Minutes to Southern States" (gas station) or even "250 Minutes to Home". All without entering any "destination"! Then I have a co-worker who was in a rental car when it said "Turn Left". But the turn wasn't really visible so they missed it and went around the block. GPS says "Turn Left" but again they missed it. Third time around it comes out with "I SAID Turn Left!" Programmers get bored to.My all time favorite was about 12 years ago, when Microsoft Excel had a secret key sequence that caused the entire screen to be replaced with a fully animated version of the Star Trek screen, with onrushing stars and everything, where the programmers then scrolled up the screen like credits in a movie. No wonder the darn program file was huge... Quote Link to comment Share on other sites More sharing options...
Smiling Jack Posted April 30, 2015 Report Share Posted April 30, 2015 (edited) Jack,At some point you are going to have to spill the beans! I was hopinmg to attract a few more guesses. I will post the answer on Saturday. In the mean time, here is a clue: The failure to turn on EV+ at a frequent destination has something to do with distance.

kostby Posted April 30, 2015 Report Share Posted April 30, 2015 (edited) OK, I'll take a stab. Is it because Ford is tracking the time and location, and attempting EV+ only at final destinations?You mean, uh, the cemetery? ;) Edited April 30, 2015 by kostby Quote Link to comment Share on other sites More sharing options...
markd Posted April 30, 2015 Report Share Posted April 30, 2015 That would be my guess too, stevedebi, mine always goes in EV+ about two miles from my house. Quote Link to comment Share on other sites More sharing options...
stevedebi Posted April 30, 2015 Report Share Posted April 30, 2015 That would be my guess too, stevedebi, mine always goes in EV+ about two miles from my house.Two miles! Mine is only about 1/4 mile from home. Quote Link to comment Share on other sites More sharing options...
plus 3 golfer Posted May 1, 2015 Report Share Posted May 1, 2015 That would be my guess too, stevedebi, mine always goes in EV+ about two miles from my house.Is 2 miles a straight line shot to the EV+ destination? Down hill / uphill? Elevation change? What is the SOC at the start of EV+ and the SOC at the EV+ destination (or battery symbol % if SOC not known)? Assume one can get 5 miles kWh at a slower speed. Then, the energy required to go 2 miles = (2 miles) / (5 miles / kWh) = 0.4 kWh on level ground. SOCMax. = 0.69*1.4 kWh = 0.96 kWh. SOCMin. = 0.33 * 1.4 kWh = 0.45 kWh. So, the usable energy from the HVB is around 0.5 kWh. I wonder if the algorithm keeps track of continuous distance in EV mode when approaching an EV+ location such that the EV+ range might be incrementally changed based on such distance and the direction of approach. This would make sense to do especially in the Energi. Quote Link to comment Share on other sites More sharing options...
markd Posted May 1, 2015 Report Share Posted May 1, 2015 It has a couple of turns and I never get above 25mph, it might not be related. The ice usually runs in the mornings when I go out for a mile or so. Maybe the fact that it's getting warmer or it is broken in, 7500 miles, but I'm getting a solid 50mpg plus now. A four mile trip to the store averages about 70 mpg! Quote Link to comment Share on other sites More sharing options...
plus 3 golfer Posted May 1, 2015 Report Share Posted May 1, 2015 I think speed has a lot to do with it as at 25 mph one likely will get over 5 miles per kWh and it a lot easier to stay in EV/EV+ mode and even go up moderate grades in EV.

fbov Posted May 1, 2015 Report Share Posted May 1, 2015 Remember, EV+ is just an increase in ICE threshold. Speed has nothing to do with it if you keep the throttle below the ICE threshold. The 1/3 mile max distance feels about right, too. I'd love to have it a mile out, but it's never happened. And to Jack's tease, you have to leave the EV+ regions for it to work when you return. I get into EV+ returning from a 4 mile trip, but not a 1 miler to the pharmacy I forgot to hit on my way home. (Where can I get some memory; I seem to have misplaced mine...) Have fun,Frank Smiling Jack 1 Quote Link to comment Share on other sites More sharing options...

Have fun,Frank Frank has arrived at the correct answer. And he has also explained the behavior! My office is less than one half mile from my home.

hybridbear Posted May 4, 2015 Report Share Posted May 4, 2015 I see similar EV+ behavior. My office is 1.3 miles from home. I don't drive to work often but I did enough this winter than it shows EV+ for work and home. But usually driving from work to home won't show EV+, only if taking a longer drive and driving near work and then near home will I see EV+ twice.

shinytop Posted May 23, 2015 Report Share Posted May 23, 2015 I retired three weeks ago and today went back to the office for the first time since. I was surprised that it still went into EV+ mode. Quote Link to comment Share on other sites More sharing options...
