2017 platinum battery use question

[nuspi32]

I have a 2017 energi I noticed when I drive it and its in ev later mode I still see the battery percentage going down even when I do not have it in ev now or ev auto mode

I use it a lot in ev later mode.  is the battery still being used when in this mode is this normal.

Of course the battery is being used.  Another name for EV Later is Hybrid mode.  There is only one high voltage battery in the car.  When you select EV Later the car saves 95% of the current battery SOC.  If you make multiple stops at each start it saves 95% which means the SOC is going down.

When you put it in EV Later, assuming it is not at 100% charge, it keeps the current charge as it's "set point".  From there, it will go up by as much as 2% and down by as much as 5%.  Depending on the load on the car, it might or might not run the ICE as long as it is within that 7% range.  When it gets low, it will run the ICE to charge back up to your set point.  It is basically acting as a hybrid with your current set point as the middle of the range.  This is the same behavior as a Fusion Hybrid all the time, and your Energi when it is out of range on the EV portion of the battery.

 

If you are above 95% when you switch to EV Later, it will put 95% as your set point, to leave a little room for regenerative braking.
