Ok, not to burst anyones bubble, but are we all talking apples to apples. If I start in EV now, then switch to EV later, then switch back, I think it counts the EV portion of the hybrid miles and adds them to your EV now miles in the trip report. So you could accumulate quite a few EV miles in the trip report screen. When I think of how many miles can you drive on a battery charge, I assume you are starting in EV now and leaving there till it switches to EV Auto, which is when the blue battery display goes to 0. You can still rack up a few more miles on the hybrid portion of the battery, but I don't count those. My rules, not sure if everyone else is playing by them or not??
So how do you max out on my rules.
1. The slower you go the farther you go. Highway speeds really reduces the miles.
2. Don't use the brakes, coast as much as possible. Heavy traffic is bad for the miles. I drive pretty empty roads and it helps.
3. Regen with low gear rather than the brakes if at all possible.
4. Roll through stop signs, keep moving even if slow.
5. Don't use any accesory power, no heat or ac, keep window open to keep battery as cool as possible
6. Accelerate slow, 2 bars max and less if possible. Acceleration and braking reduce miles.
7. MY theory, but using low down hills max's regen current and I believe helps equalize the battery for max capacity. I have no real proof, other than my miles jumped by 5 and I don't know why, except I started using low. The air temp got a little warmer too, might have been it.
8. Also very biggy, if you can't coast, then regen as much as possible. I count that extra charge under MY Rules and they get you more miles.
Obviously you have to have the optimum conditions to do this and a battery that can deliver 5.5KW or so.
BTW, my 2017 delivers 5.5KW on a charge, and I get about 28 EV now miles regulary. The car tells me I can get 28-31 miles depending on the day. I usually get 1-2 miles less than what it says. I drive 24 miles one way to work. The best day I had 22% HVB left when I coasted into the parking lot. The math say I should have gotten 31 miles that day.
Rbort says he has gotten 37 miles on one charge, if he is playing by MY Rules. He might have been down hill in elevation, which will increase the miles. I have to climb a big hill when I drive to my other plant, and I use almost triple the KW going up as going back home down, it is only about 3 miles away from my house.
