I think there is a lot of overlap with the cars. Sure, there are differences. But some times the points overlap depending on what you're trying to explain.
Though I'm *completely* missing your point on why EV+ makes more sense in the Energi... The Energi would be much more likely than the Hybrid to be making it home without starting the ICE... If you're still in EV mode then EV+ isn't going to do anything at all...
Sure there's a reason to only charge the Energi to 50%(or 40% if that seems to be best charge holding battery longevity number). I park my car Friday afternoon and don't need it again until Tuesday morning. It would be best if I could just have it in a "storage charge" mode and charged to 40%, then when my Go Time comes up Tuesday morning it finishes charging up to 100%.
I think you're confusing some terms...
-"Value charging" is what you could set up to have it delay charging at all and I don't know of anything that would delay it more than a day.
-"Go Times" are what you'd set up to make sure your car is charged and or temp controlled(attempted) by a specific time(but it won't delay anything)
-"EV Later" is only used while you are actually driving and it will just put the car into hybrid mode at whatever set point the battery is currently at. I.e. you want to keep the EV battery held at 95%.
I'm aware of the terminology. When I set up Go Times I checked out value charging; as I recall it was part of the process, or maybe I just did them together to see if there were cheaper rates.
The Go time will consider the departure time and ensure the HVB is fully charged when you are ready to go, and I believe it will begin early regardless of value settings. You mentioned it might be best if the Energi waited until it had to for charging the HVB in order to be ready at departure. It does exactly that with the Go times. That is why I brought it up.
In my opinion, EV+ doesn't make much sense for the Hybrid. If you run the battery all the way down, it will have to charge up immediately when you start, causing you to run the ICE while charging at first run. My Escape Hybrid tended to do that (that tech required the engine to run at each start up), and it is pretty much the worst for MPG. It would be better if there were more charge available when starting - at least you could get a start and logically kick in the engine once you got going. In addition, unlike the Energi where the grid will charge the HVB, the battery will be in a lower SOC overnight. I think it was easier for Ford to just put in a lot of the same software, and that is why EV+ is in the hybrid.
Along those lines, they could have customized EV Later so that it used the higher capacity HVB - but they didn't; it works the same as the Hybrid, and I would bet that the computer algorithms are just about identical once you hit the EV Later swtich.
There. Despite what I said, we just spend time discussing Energi topics on the hybrid forum - not many will be interested here.
