Hi Bob. Doesn't sound that unusual really.
I posted extensively during my first winter, and gave various tips and experiences. Look a few posts down the following thread, see if it ties up with your experience:-
A longer search will reveal more of my 'experiences' which might be informative. With practice and using the tips I discuss, you should find 70 miles range in it. Maybe.
I suspect you might be suffering from a 5 to 10% battery degradation by now. Remember these are the 'first gen' NEC LMO cells, the same that the largest fraction of Leaf owners generally say they lose the first bar (15%) at 25~35k in the US. So if you were to add that back in, then it looks about right.
Renault, at least to their credit, state 56 miles in their brochure for the Fluence range in winter conditions. I think that's a little pessimistic for a new battery, but certainly not far out.
Multiple short runs in a day gives terrible range because you end up repetitively heating the car which sucks vast amounts of electrical energy. You need to aim charge at least every other time that you stop!
I restate my very best tip for heating in the car, as I have done many times - set the vents to footwell only and set the fan to a single blade. You want the slowest fan speed because what you push into the car will, somewhere, push warm air out. This turns out to be the biggest loss. On the Fluence, the footwell setting gives just enough flow to the screen and side windows to stop you misting up. Set 19C to stave off the cold, or up to 22C on taste, and leave that setting so it runs at a low but constant setting. The eco cuts the heating on and off and this seems to suck juice very badly. This setting will save your battery energy, I promise!
Also block the gap around the column adjust with some thin foam, or any other padding you can find. Yep, that IS
a cold draught coming from there. Hadn't noticed? You will now!!.....
