I live in KY, but here’s a suggestion.
The consensus from many posts in several threads is that you will get a much better driving experience with regards to efficiency, economy, power, and comfort if you do not let the battery deplete to 2 bars/0EV range. This is especially true at high speeds and on steep hills, however on speeds under 60 and flat or rolling hills, I have found that you don’t need to. Try it both ways (same travel direction and area) and you see.
With sufficient charge, the algorithm is more able to select and switch among its several power flows to achieve better power and economy usually without having to rev as high and summon what some call the “angry bees”. This is especially true on longer or steeper inclines.
I understand the desire to use all the SOC on a trip for economy’s sake as I share that too. What I do is use a little EV SOC locally to get on the highway and then switch to HV so as to have plenty of charge available. I mostly keep that level and never get a loss of power or the angry bees that way. Then when I am in EV range of my destination, I switch to EV and try to end with 3 or 4 bars. It’s like the best of both worlds or having your cake and getting to eat it too.
Let us know what you try and how it works.
