cegarbage Posted March 22, 2015 at 06:12 AM Report Share Posted March 22, 2015 at 06:12 AM (edited) I live up a hill. When I leave my house, I have to drive 100% of the time downhill. If I leave my home with an 80% charge, by the time I'm on the freeway it's normally up to 85% from all the downhill braking I do. So, I'm curious if I leave my home at a 100% charge, is there a spot to capture all that energy, or am I better served by only charging my car up to 95%?

larryh Posted March 22, 2015 at 09:29 AM Report Share Posted March 22, 2015 at 09:29 AM The car will not allow regen if the actual SOC of the HVB exceeds 98.5%. The car does not show the actual SOC of the HVB. What you see on the MFT screen is displayed SOC. When the displayed SOC is 100%, the actual SOC is between 96% and 100%.

murphy Posted March 22, 2015 at 10:58 AM Report Share Posted March 22, 2015 at 10:58 AM If the HVB is full the engine will be used to provide the back pressure. It will operate like an air compressor. No fuel will be used. Since you had to expend energy to climb the hill you might want to leave room in the HVB to recover some of it on the way down.

It will operate like an air compressor. No fuel will be used. Since you had to expend energy to climb the hill you might want to leave room in the HVB to recover some of it on the way down. Quick note: It'll only do the above if you're driving downhill in L, or it may do this if you have Hill Assist enabled (the button on your shifter) while in D. If you stay in D without hill assist, the friction brakes are used instead. If the battery is full, there is no place for additional regenerated energy to go, so either the ICE will spin up to burn off the additional kinetic energy, or the friction brakes will engage.

cegarbage Posted March 22, 2015 at 05:11 PM Author Report Share Posted March 22, 2015 at 05:11 PM Is there anyway to set the car to only charge the car to 96%? Quote Link to comment Share on other sites More sharing options...
larryh Posted March 22, 2015 at 05:30 PM Report Share Posted March 22, 2015 at 05:30 PM (edited) No, unfortunately there is no easy way to tell the car to charge to only 96%. You have to stop charging manually before it reaches 100%. Edited March 22, 2015 at 05:31 PM by larryh Hybridbear 1 Quote Link to comment Share on other sites More sharing options...
rbort Posted March 23, 2015 at 03:15 AM Report Share Posted March 23, 2015 at 03:15 AM You can have the car text you when it reaches 90 or 95% charge whatever you like but then you need to respond to the text by going to the car and unplugging it before it goes any higher on the charge level than you want it to. -=>Raja.

cegarbage Posted March 24, 2015 at 11:37 PM Author Report Share Posted March 24, 2015 at 11:37 PM Another newbie question...In regards to my original post about capturing energy..If the plug portion is exhausted (or I forget to plug in), will regular hybrid mode capture energy and store it in the same manner as the plug in portion. I was pleasantly surprised to go 30 miles today in EV with 71MPG. I do live at the 1800 level and drop down to sealevel in the first 6 miles of the 30 mile ride. When the car is in plug in mode, I can flip over to EV later and see energy recaptured as the percentage goes up. However, in EV only mode the EV later is not active so I can't see how energy is recaptured. Quote Link to comment Share on other sites More sharing options...

lonzo71 Posted March 25, 2015 at 06:33 PM Report Share Posted March 25, 2015 at 06:33 PM From my understanding, when you hit 0% and it turns into hybrid mode, it wont charge the plug in portion, it will only charge the hybrid side. Quote Link to comment Share on other sites More sharing options...

If you are driving on flat ground, this is true. The ICE itself will not bring the car back out of hybrid mode. However, if you travel downhill to the point where you're regenerating constantly (using hill assist, coasting, driving in L), the car actually will continue to regenerate past the hybrid level and start putting miles back on the battery. You will then have access to EV Later again, EV now, etc. Hybridbear 1 Quote Link to comment Share on other sites More sharing options...

It did not automatically change back to EV Auto or EV Now, but it allowed me to do so. We had 3 or 4 miles of range showing once I switched back to EV Auto. I expected it to change itself so that's why I went so long with it showing the full 2D hybrid battery icon before deciding to press the button and see what happens.

cegarbage Posted March 27, 2015 at 12:04 AM Author Report Share Posted March 27, 2015 at 12:04 AM I am not seeing a MFT display in my 2015 Fusion, or any display that shows this. Can you point me to right side/left side, and possibly a photo? I only see the EV regenerated data when I turn off the car on the left side. I'd love to see in real time.

cegarbage Posted April 4, 2015 at 02:33 AM Author Report Share Posted April 4, 2015 at 02:33 AM Since I start driving downhill, it was suggested here to only charge my car up to 95%. I started observing the leaf icon on the touchscreen. The battery percentage on the leaf icon on the touch is always the same as the number that shows when I toggle the EV button and view the percentage remaining on the left dash..unless it's greater than 95%. It appears when the car is fully charged, the leaf icon on the touchscreen will say 100%. However, on the left side of the dash it never goes above 95%.Anyone know why?

Hybridbear Posted April 4, 2015 at 01:08 PM Report Share Posted April 4, 2015 at 01:08 PM The car won't let you go into EV Later until you discharge a certain percent. We noticed this on our road trip when we wanted to switch to EV Later almost immediately after starting the car since we only had to drive 1 block from the hotel to the freeway. Unfortunately the car wouldn't allow this and wasted electricity on the freeway. On subsequent days I solved this by taking the city route for a mile or so and then getting on the freeway and switching to EV Later.

That 5% is the hybrid part of the battery, i believe and that is why in the car, it'll say 95% even though its fully charged and the MFM, ect will say its 100% Quote Link to comment Share on other sites More sharing options...

So any charge level above 95% will be drained down before the car will start the engine and switch to hybrid mode operation (EV later selected). The hybrid part of the battery is actually about 7%, from 21.5% charge level of the main battery down to 14.5%, but can be used at any time by selecting EV later at any charge level. -=>Raja.

cegarbage Posted April 12, 2015 at 01:36 AM Author Report Share Posted April 12, 2015 at 01:36 AM Since I drive downhill and have the ability to regenerate 5% by driving, I decided to set an alert to notify me when the car is 90% full. I did it a few times, but each time I walked out to my car, it was already 100% full. Today, I dropped the alert down to 80%. I immediately walked out to my car and it was 91% charged. Is this normal? Quote Link to comment Share on other sites More sharing options...
rbort Posted April 12, 2015 at 02:46 AM Report Share Posted April 12, 2015 at 02:46 AM I'm not sure, there seems to be some delay in the notification. I haven't checked mine lately to see how quickly it lets me know when it reaches the threshold you set. -=>Raja. Quote Link to comment Share on other sites More sharing options...
murphy Posted April 12, 2015 at 10:33 AM Report Share Posted April 12, 2015 at 10:33 AM In my experience the text message alert system is very flaky. I've received an alert that charging has started and never received the charging complete alert. I've received the charging complete alert three times in a row. I've received the charging complete alert as much as 4 hours late. The car has to notify the website. If it has a weak cell signal that can be delayed. The web site then has to process the alert and create a text message and send it. My garage has steel doors and is covered with stucco. Stucco is installed on a wire mesh. The only way for the cell signal to get into my garage is through the windows. Hybridbear 1 Quote Link to comment Share on other sites More sharing options...
cegarbage Posted April 12, 2015 at 03:09 PM Author Report Share Posted April 12, 2015 at 03:09 PM From what I have seen, when I initially plug in with a depleted battery, it will give me a time notification in the @5.5 hour range. Normally, the ETC time to complete on the app will shorten by about 20 minutes or so over the course of the charge. What I am noticing is it's normally finishing an hour earlier. Based on that, I don't believe it's a weak signal notification at the end of a charge causing the issue. One day when I'm home I'm going to setup 10% increment notifications and see if I can figure out how it's getting so far off. Quote Link to comment Share on other sites More sharing options...

I havent, and thats what I was saying, is when you switch modes, the car will not say 100%, even though it is fully charged. Its about wording...
