I have just bought my first hybrid. It's a 2017 Fusion Hybrid Titanium and I have had it for about 1 week.  I have driven it on the highway, and around town.  It seems like no matter what I do, the battery charge indicator only peaks at 50% full.  I have driven about 100 miles so far probably 50/50 highway and city.  I'm averaging 43 MPG which is great.  It seems to charge well when I stop and coast.  


My Questions:

Since I just bought the car (used - it was a rental car before).  


1) Should I make sure it will fully charge the battery?  How do I fully charge it?


2) Should I expect the gauge to hover around 40%-50% at all times?



Thanks for the help. I'm a hybrid newbie!

On average, that is what it will do. It is designed to operate this way. The car has lots of software controlling the battery management to achieve long battery life and maximize fuel efficiency. In my experience, the only time I notice the battery achieving full charge (as indicated by the dashboard graphic) is when descending a long grade or decelerating on the interstate exit ramp.  


Focus your efforts on smooth gentle acceleration and gentle braking (not the battery SOC). You are already off to a very good start with your 43 MPG.

The HVB is also used for regenerative braking so if it's full it can't do that. 50% is average. It will go significantly above and below that at times. It's mostly automatically controlled and you can't change it much. You can sometimes milk some more EV distance with a light foot but that's not necessary. Drive normally, a steady foot on the pedal yields the best results. Getting on and off the pedal yields the worst. Look at lights as far ahead as you can and coast up to them, traffic permitting. Many may pass you but don't worry about it and relax. You're getting 40mpg and they're getting 20. Your blood pressure will be lower and you'll live longer.

That dash gauge is just an approximation of the battery charge.


Not to worry, when you drive it down a long mountain road, it will fill up.

Agree with all that's been said.  I've had the HVB to really, REALLY low charge as well as topped off.  It all depends on things going on with the car.  If you use cruise control on a trip and encounter a good downhill area, keep cruise engaged and let the cars attempt to maintain speed kick in regen braking.  That'll put some charge back in the HVB.


You're pretty much in line with mileage ... just keep plugging away!
