I have a newer Rav4 Hybrid for work - I wonder if you might give some tips, if it's even applicable. The Rav goes in and out of EV mode even at 100kph (on slight declines) and uses battery to propel itself. It appears to try very hard to maintain the battery directly in the middle of the gauge (whatever percent that equates to).
When driving around town, I can very easily keep it below the throttle position where it will stay fully in EV mode, until the battery is depleted. At 80kph on level ground, it's right at the edge of wanting to stay in EV, and could probably be convinced to stay in one or the other.
Any thoughts about managing when the engine runs? Better to let it drive as much as possible in EV mode, then let the engine run for long periods and bring the battery back up? Or, better to keep the battery bar right around the middle, with more frequent dips in and out of EV?
