Guys I've been recharging my Energi's battery while driving, in a typical 20 min drive to work and back home I am able to add 20%, the other day I drove 34 miles from NJ to NY and my charge level was 36% and when I arrived I had 76%.
This is what I am doing. Don't let the EV battery drain below 20%, put it on ev later mode. Now the trick is time your regen braking, by switching it out of ev later mode and putting it auto mode, then when you are going to accelerate tap it twice to bring it back to evlater mode getting about 48 mpg by driving this way. When I get the batter to be in the 90% then I only drive electric until it drops to 20% and I start the cycle again.
When you brake or coast in evlater mode the energy that is captured only goes to the allotted hybrid mode storage of the battery.
By switching it to EV Auto or EV all that energy goes back to charge the long range or EV section of the battery, thus fooling the software and the care self charges while you coast and break.
So to recap start 2 taps (Evlater engaged) when about to break or coast 1 tap for Auto mode, then 2 taps to evlater. Try it.
I live in an apartment building and there is no charging stations, unless I go to the dealer or my brothers house, so this comes in very handy.
